PART A: BACKGROUND
1. Country
Profile
ituated in Northeastern Africa, Sudan covers a land area of
about 2.5 million square kilometers, the largest land area on the African
continent. Of this area, 34% is classified as desert, 20% as shrub/ semi desert,
38% as woodland/forest, 7% as agricultural and 1% as swamp/wetland. The land
use is characterized as arable land (5%), permanent crops (0%), permanent
pastures (46%), forests and woodland (19%) and other (30%) according to 1993
estimates. Sudan lies between 15 00 N, 30 00 E geographic coordinates.
It shares its extensive borders with nine neighbors: Central African Republic,
Chad, Congo, Egypt, Eritrea, Ethiopia, Kenya, Libya and Uganda. It possesses a
stretch of coastal land bordering the Red Sea. The Sudan is one of the least
developed countries (LDCs) in the world.
The population
was estimated at about 30.3 million in 1999, with an average annual growth rate
of 2.63 per cent (1993-1998).
Population density varies widely across the country with 67% rural and
33% urban with a total average population density of over 12 persons per km2
though it may exceed 50 persons per square kilometer on arable land. Over
80% of the total population is considered rural sedentary, and is divided into
approximately 130 tribal and sub-tribal groups, and speaks 100 languages. The
urban population has increased by 75% since 1975 and is set to increase nearly
50% again by 2015. Large areas are virtually unpopulated while the Land close
to the Nile is relatively densely populated. Khartoum, the capital, with
current population of nearly six million including some two million internally
displaced people, is by far the largest urban settlement, followed by Port
Sudan.
Sudan is
endowed with extensive resources for economic development. The primary natural
resources of Sudan are water. There are four main water resources in Sudan:
rain fall, the Nile river, ground water, and the Red Sea. The Nile River is the country major source
for irrigated agriculture and is generally considered as one of the major
topographical features of Sudan along with its headstreams, the Blue Nile and
the White Nile, and the tributaries of these rivers. The Nile River and its
tributaries are the most prominent surface water sources. The White Nile originates
in equatorial Africa and the Blue Nile originates in Ethiopian Highlands. The
two rivers unite at Khartoum to form the River Nile which flows northward
through Egypt to the Mediterranean Sea. Together, these rivers annually
discharge about 51 billion cubic meters of water. The largest ground water
reservoirs in Sudan are contained between main aquifers: The Nuba and the Umm
Rawaba aquifers which contain good drinking water quality. The Red Sea is the
Sudan’s sole marine seashore, and it is the main source for minerals, fish, and
salt. It provides an excellent environment for fish farming. Presently marine
and coastal pollution close to Port Sudan (Sudan’s main port), industries,
shipping, reclamation, and urban construction are the main factors contributing
to the degradation of marine biology.
One of the main
physical resources is its fertile agricultural land. Large areas of cultivable
land are situated in the region between the Blue Nile and the Atbara and
between the Blue Nile and the White Nile. Arable land, at some 81 million ha.,
makes up to 32% of the total land area, but it is estimated that only 21% of
arable land (17 million ha.) is actually cultivated, this area having more than
doubled over the past 10 years. A further 25% of land area is woodland or
forest while 20% is semi-desert or scrub and 1% is swampy wetlands. The
remainder, 22%, is pure desert. In the North, many areas that would otherwise
be cultivated land are home to approximately 100 million head of various
species of livestock, mainly cattle, sheep and goats.
Sudan has extensive forestry resources with different
varieties. The forests and woodland of Sudan ranks the 3rd in Africa
and the 15th in the world. The forestry resources in terms of round
wood are fairly high and almost 67% are in Southern Sudan.
Sudan characterized with a large geographical expanse spanning
various climatic zones and ecological conditions. Its terrain is generally
flat, featureless plain; mountains in east and west. Its climate range from tropical
in the south to arid (desert) in the north. Rainfall varies tremendously with
many desert areas of the arid northern region frequently experiencing total
absence of rain for yeas at a time, while in the southern tropics annual
rainfall can be over 1,500 mm. Khartoum, at 390 meter above sea level, has an
average rainfall of 200 mm pr year while the central savannah belt of the
country has between 440 and 800 mm annually. The rainy season occurs between
the months of April and October and decreases in duration in the northern
latitudes. Rainfall reliability also decreases relative to latitude. Mean daily
maximum temperatures exceed 40o C in the northern half and in the
high thirties in the rest of the country except for the highlands along the
southern border. Desertification, according to the National Drought and
Desertification Control Unit, affects around 50% of Sudan’s total land area due
to overgrazing, over-cultivation, inappropriate land use methods and
deforestation. The Sudan is traversed by 9,000 km. Of the Nile and its
tributaries which provide the main source of water for the whole country, while
the tributaries which provide the main source of water for the whole country.
2. Socio-economic Perspective
Sudan is
considered to be one of the poorest countries in the world. Its poor economic
performance that has led to poor infrastructure, the civil war in the south and
recently in the east together with years of
drought that covered large parts of the country have exacerbated the poverty
situation in the country despite its considerable wealth of human and natural
resources.
Over the past
few decades, Sudan was buffeted by civil war, chronic political instability,
adverse weather conditions, high inflation, a drop in remittances from abroad,
and counterproductive economic policies. The private sector's main areas of
activity are agriculture and trade. Agricultural production is identified as a
critical area in the government of Sudan’s (GOS) developmental objectives,
which is currently suffering from expanding desertification in the North where
roughly half the population lives. Sluggish economic performance over the past
decade, attributable largely to declining annual rainfall, has kept per capita
income at low levels. All these factors in addition to recurrent droughts,
chronic food security problems, and regional instability have contributed to
population displacement and an ongoing refugees crisis.
The Sudanese
economy suffers from internal and external imbalances. In the eighties, budget
deficits grew at an annual rate of 70%, while the long -term public debt as a
percentage of GNP grew from 29% in 1975 to 97% in 1986. The government’s
National Economic Salvation Program (NESP) was enacted in 1990 to combat
economic decline and incorporated currency devaluation and price/trade
liberation.
Agriculture continues to dominate the
economy accounting for 40 per cent of GDP, over 20 per cent of
exports (is the dominant source of
export earnings in the form of cotton, livestock, and oil seeds) and employing about 75% of the labour force and provides raw materials to about 70 per cent of
manufacturing industries. Dependency on agriculture, and as a result on
rainfall, for many parts of the sector exposes the economy. This is even more dramatic when one
considers the low level of industrial inputs to the agricultural sector.
The 750 kilometer-long Sudanese coastal
zone along the Red Sea contributes to the national economy through
import/export, seasonal farming, fishing, and livestock grazing. The area is
relatively poor in biological productivity and suffers from serious water
shortages during dry seasons. Between now and the turn of the century, the
population of the coastal city of Port Sudan is projected to grow at a rate of
twice the national average.
The structure of the industrial sector mainly consists of
agro-industries. The main industries in
the country process agricultural raw materials. This is done at relatively low technological level, which does
not allow industries to be competitive either locally or internationally. The
performance of the manufacturing sector is dependent on the supply of inputs
from the agricultural sector. At the heart of the industrial strategy for the
future development of the industry in the Sudan lies the development of agro-industries
and their linkages with agriculture. The industrial sector has a considerable
potential for contribution to employment, productivity, trade and overall
economic growth and development.
3. Environmental Problems
in Sudan
Environmental problems occur at the level of relations between
people and their environment, that is, their non-living (soil, water, air) and
living (plants, animals) surroundings.
People intervene in their environment, and are affected by the resulting
changes because the environment is crucial to their survival.
Sudan has been
confronted with many drastic changes since mid seventies. The era of the
seventies and eighties were calamitous as they were accompanied by the
appearance of many distressful phenomena. Since that time the country
experienced serious environmental degradation due to natural disasters such as
succession of drought and desertification in the western part, flood and man
-made disasters such as illicit tree cutting to supply fuel wood and to practice
mechanized rain-fed agriculture and among all of these the civil strife which
is considered one of the most devastating humanitarian crisis of the present
time. IN addition to these problems, Sudan suffers from many other
environmental problems such as loss of wild life and biodiversity, air
pollution particularly in urban cities as a result of industrial activities and
traffic conjunction, and deficiency in energy sources. However, based on
considerable working experience, author of this paper believe that the
magnitude and impact of these problems do not qualify them to be considered as
the major environmental problems. Therefore, The major problems are:
Displacement, agricultural failure and land impoverishment, desertification,
soil erosion, inadequate supplies of potable water and impact of environmental
degradation on women. The main natural hazard is the dust storms.
Sudan is party
to many International agreements on Environment such as Climate Change,
Desertification, Biodiversity, Endangered Species, and Montreal Protocol.
4. Energy
The energy resources in Sudan are biomass (67.2 percent),
petroleum (16.6 percent) and electricity (mostly hydro-electricity 2.2
percent). The national electric power
system is generated from thermal stations (52.4 percent) and from the three
hydroelectric generating plants (47.6 percent) of Rosseirs and Sennar) on the
Blue Nile, and Khashm El Girba on the Atbara river. Total available capacity drops frequently during the dry season. Thermal stations are also facing serious
maintenance and rehabilitation problems.
Severe shortages, unreliable services, and frequent interruption of
electricity, which have been a hindrance to the continuity, and efficiency of
the manufacturing sector characterize power supply.
Energy use is characterized by a high reliance on traditional
fuels. Of the estimated total energy consumption of 6.7 million TOE in 1992,
the overwhelming majority continues to consist of firewood, charcoal, and other
forms of biomass. Commercial energy consumption is satisfied by imported oil
and a small percentage of electricity. Because of the high reliance on
traditional fuels, its consumption is about six times higher than commercial
energy consumption. Total installed electric generation capacity is 450 MW, of
which half are oil-fired thermal plants-hydro power accounts for the rest.
Public access to electricity is very limited, only 8% of the total population
has access to the electricity, resulting in per capita consumption of about 45
kWh per year. Sectorally, transport, industrial and residential consumers
remain the largest consumers of electricity.
Sudan is an energy-rich country relative to its solar and oil
resources. Annual average solar insulation is very high throughout the country,
ranging from 436 W/m2 in the south to 640 W/m2 in the north. However, this
potential remains largely untapped. In addition, Sudan possesses large oil
bearing areas in the northwest, along the Red Sea, and in Unity-Tallyho in
southwestern region. Total confirmed oil reserves were estimated to be about 2
billion barrels in May 1987, of which 5000 million were considered to be
recoverable.
5. Desertification
Desertification is the conversion of productive rangeland or
cropland into desert like land. It is usually caused by a combination of
overgrazing, soil erosion, prolonged drought and climate change.
Desertification is one of the most serious environmental problems affecting
more than 60% of the country. It manifests itself in declining land
productivity, food shortages, shifting sand dunes, shortage in fuel wood and
deterioration in environmental quality. Moderate desertification causes a 10% -
25% drop in agricultural productivity; where as severe desertification can
result in a loss of 50% or more.
Desertification in Sudan is largely attributable to the state
of poverty and underdevelopment that resulting in imbalanced human activities
and uncontrolled utilization of natural resources. These factors in combination
with the characteristics of the physical environment such as natural disasters,
shortages of rainfall and drought had eventually leaded to desertification. In
the years 1984/1985 and 1989/1990 combined effects of drought and
desertification led to severe food shortages and famine, which resulted in a large
scale movements and change in the social structure and economic
activities.
In various parts of Sudan, population pressure and in
particular among rural population contribute to environmental degradation,
putting heavy strains on natural resources and often depleting them faster than
they can be regenerated. Sudan’s primary concerns center around the
over-exploitation of its forests and marginal agricultural lands. Most of the
northern areas of Kordofan and Darfur have experienced a systematic expansion
of decertified areas around villages as a result of clearance of marginal lands
for agriculture and the use of firewood in household energy consumption. These
unfavorable conditions combined with frequent droughts led to widespread land
degradation and a decline in agricultural yields. This is particularly
important in view of Sudan’s heavy dependence on fuel wood for domestic energy
needs.
In many areas of Sudan cutting of trees is a wide spread
activity practice by both women and men. Women unintentionally play an active
role in accelerating the magnitude of desertification through their domestic
tasks such as use of forest resources for cooking and house construction. Men
especially the elite practice cutting of trees as an economic activity to generate
income through large-scale rain-fed agriculture and commercial charcoal
production.
Forests are being decimated in the north by the expansion of
mechanized farming and increasing demand for fuel wood. At current rates of
consumption versus regeneration and aforestation, all forest areas in northern
Sudan will be denuded by the year 2003.
There is a disturbing degree of correspondence between the
areas at risk of desertification and deficient in fuel wood and those areas
having inadequate land resources to feed their populations.”
Sudan falls within the zone where the risks of desertification
are great. A total area of 65 million hectares, lying between latitude 12o
– 18o N, extending across the country from east to west has been
decertified until 1976.
Poverty is both a cause as well as a consequence of
environmental degradation and resource depletion. The increasing
desertification, manifested by land degradation, erosion, and depletion. The
productivity has led to movement of people to other parts of the rural areas.
This desertification is caused by a range of factors including the
inappropriate land use methods, over-cultivation, over-grazing, and
deforestation. In addition, during the 1990s and early 1990s Sudan witnessed
many droughts that led to severe food shortages in the marginal areas where
vulnerable farmers rely entirely in subsistence production. This exacerbated
the poverty situation. The droughts of 1984 and 19990 resulted in massive
population movement either to peri-urban areas, putting pressure on the weak
service systems, or to other better-off parts of the rural areas, generation
ethnic conflicts.
Since the successive drought that hit Sudan in the late sixties
and early seventies and due to fluctuations in rainfall thereafter, many
adverse impacts occur. This lead to immigration of population of arid and
semi-arid areas to big cities and urban areas and the shift in economic
activity and therefore resulted in overexploitation of natural resources and
the various environmental problems associated with it. One of the most
important environmental problems is desertification and excessive dust storms
which lead to land deterioration due to degradation of physical, chemical and
biological characteristics of soil, increased soil erosion due to wind which
affected many agricultural schemes and reduced soil fertility in addition to
air pollution affecting human and animal health.
In 19990, Ali and Bayoumi conducted a study using remote
sensing techniques and GIS for assessment and mapping of desertification. The
study indicated that the boundary of desert in 1982 shifted about 200 km south
of the desert boundary estimated by Harrison and Jackson in 1985. The study
showed that the desert area in Western Sudan has increased from 205000 square
kilometers in 1958 to 340000 square kilometers in 1982, and shifting southwards
took place at a rate of 8 kilometers per annum.
North Darfur and West Darfur are located between lat. 13o – 14o
N. they are lying in the ecological zone of semi-desert characteristics. The
annual rainfall ranging between 100-300 mm. Those states are lying within the
affected zone by drought and desertification in Sudan, which identified between
lat 10-18o N. The areas are at risk to drought and vulnerable to
desertification if one year of drought happened. Moreover the above-mentioned
states are affected by sand encroachment.
The soil texture is sandy and sandy loam.
The GOS realized the magnitude of the desertification problem
and is trying to promote sustainable management of forests and natural
resources. Sudan has fully ratified the International Convention to Combat
Desertification in 1995. Prior to that, the country has prepared the 5-year
program to combat desertification. Recently,
UNDP has secured funds for the government to prepare the National Action Plan
(NAP) to cope with the provisions of the convention.
Despite the considerable natural resources endowment,
particularly minerals, water, fertile land and the newly discovered oil
reserves, Sudan is one of the poorest countries in the world. Mass poverty still prevails both in rural
and urban Sudan.
Information on the number of people living below the poverty
line is scarce. However, more than one source has estimated the percentage of
people living below the poverty line in Sudan to be in Excess of 90%. A study
conducted in 1994 charted the growth of impoverishment from the late 1960. From
52% in 1968, the figure grew marginally to 54% in 1978 and then leapt to 78% in
1986 and up to 91% in 1997.
According to study on poverty, half of the population of the
Sudan lives below the sufficiency level and one sixth live below the
subsistence level. About 39.5 percent of urban and 86.5 percent of rural
populations are poor (figures excluding Southern States).
Data form the Ministry of Manpower, suggests that in Northern
Sudan urban poverty was at 84.6% and rural poverty at 94.3% with an overall
averages of 90.2%. There are major regional disparities between North and South
but also within the North while other major vulnerable groups such as the
displaced and women cut across geographic differences. The most affected groups
are people in remote areas, women and children. Among the six regions covered,
Darfur ranked bottom in terms of poverty with 95.4%, followed by Kordofan
(94.2%) and Northern (93.2%). The
Southern States and those of Darfur and Kordofan are the worst off according to
an array of indicators.
The average per capita income declined from over US$ 800
equivalent in the 1960s to below US$ 300 in the late 1990s. In purchasing power
parity terms, however, the most affected areas those in remote rural areas, the
urban poor and the internally displace persons (IDPs).
As the population is set to double every 17 years, poverty is
spreading. Hard hit are the 45 per cent
under 14.
There are many causes of poverty in Sudan, which include the
civil war in the South of the country, an interplay of disasters, drought and
floods which were prevalent during the 1980s and early 1990s, high level of inflation
and removal of subsidies and price controls on essentials such as electricity,
fuel, consumer goods and government services and diverting scarce financial and
human resources away from development. The root causes of poverty are complex
and have to be seen from a historical, socio-cultural, socio-economic, and
geo-political perspective. However they could be summarized in major three
dimensions, which are closely interrelated: conflict, economic and
environmental constraints, and weak democratic governance.
The cost in human terms is powerfully illustrated by the
displacement and refugee phenomena, collapse of the rural economy and the
destruction of social services. Estimates put the current number of internally
displaced persons at about 4.4 million, most of them women and children.
People have few possibilities of employment and many lack basic
necessities such as water, food, clothing and shelter. The unemployment rate
increased from 11.14 percent in 1993 to about 16.6 per cent in 1996. The value
of salaries has over recent years declined rapidly despite periodic adjustments
by the GOS. In 1995, the minimum pay of the civil service represented only 36
percent of its value in 1990, which is a loss of 64 percent of the value of the
wage. In 1995, the real salaries of the senior civil service were only 28
percent of their value in 1990, and the middle scale salaries lost about 60
percent of their 1990 value. The
situation is much worse in the rural areas especially in the Southern States
which are still under the role of war and civil conflict.
Poverty alleviation is not easy, given the low capacity of the
country's productive sectors at a time when Overseas Development Assistance has
declined to the point of being almost non-existent. Basic social services are
in serious decline. Agricultural productivity in Sudan is relatively low and
utilization of the installed capacity in the manufacturing sector is extremely
low for many plants. Investments in the
replacement and renewal of plants were neglected over the years and both
machinery and infrastructure have become old and obsolete. The government has therefore, adopted
measures to accelerate growth by stimulating the private sector and encouraging
local and foreign investments in the productive sectors of the economy.
Employment opportunities are very limited, so the small-scale
informal productive sector could be considered as a potential sector for
absorbing the growing labor force. The entrepreneurship needs to be developed
for establishment of micro and small informal enterprises for creation of
employment especially in the rural areas.
Inter-tribal conflicts are certainly not new phenomena in Sudan
as traditionally; local conflicts arose over utilization and ownership rights
of resources, such as water, grazing areas or cultivation lands. This brings us
to another aspect of the conflict: social differences.
The competition over natural resource among herders themselves
and herders and farmers has increasingly been recognized as a root cause of
violent conflict in the Sudan. It is estimated that resource based conflicts
are inflicting higher human and material losses, year, than the main
North-South itself.
An estimated 20 to 35 percent of all households worldwide are
headed by women. Such households may be headed by unmarried women or married
women, often with children as a result of the absence of husbands for economic
or political reasons.
In Sudan, a high percentage of households are headed by women
most of them are migrants and displaced who were affected by succession of
drought in western Sudan, but most importantly the war in the southern part of
the country.
Concerning the relationship between women and environment,
women represent an important link in the chain between development and the
environment. In the first place, women are instrumental in many activities that
both utilize or affect the environment, such as agriculture, animal husbandry,
handicraft production, food preservation and preparation, and water and fuel
collection. Secondly, due to the nature of women’s relationship to the
environment that tends to be at a basic and subsistence level, they are much
more adversely affected than men by changes in the balance of nature when they
occur.
The increased population growth in rural areas, intensive
cultivation and excessive land use have depleted the land fertility. This has
resulted in women farmers of Kordofan and Darfur working harder to farm larger
areas for the same production as in the past. They travel long distances to
scattered fields in order to find sufficient land. Thus, their workload has
been intensified as a result of land degradation.
In addition, in Sudan as well as in many developing countries,
women are the poorest of the poor. In Sudan, there are multiple roles that are
socially assigned to women in family and hence in their environment, Sudanese
women have traditionally been home-maker. This includes bearing and raising
children, carrying water for daily needs, collecting fuel for cooking. In
addition, women provide economic benefits directly to the family in many areas
through their own labor. Women are very active in food production including
cultivation and harvesting, and raising domestic animals.
Women, especially in rural societies, most often shoulder the
burden of fetching water and firewood for their families which constitute
double burden of work on them in addition to domestic responsibilities.
The traditional method of cooking causes health hazards because
of the smoke that comes up from the stoves, so this adds another burden on
women to find energy supplies or limit the food to be cooked for the family.
The most interesting fact is that in many cases it is hard to
explain if women unintentionally contribute to environmental degradation or
women are victims of environmental degradation. For instance, in Northern
Kordofan province, the first areas to be felled by the women (who take the
responsibility of collecting fuel wood for cooking) are at perimeter of the
town, and these are gradually extended. The average distance to the wooded
areas increased almost eight times in ten years. During the 1960s, women used
to make five to eight trips per day from the village to the wood-lot carrying
the wood on their heads, but between 1970 and 1978 only two to three trips a
day could be completed.
All of these problems and conflicts directly affect the well
being of the Sudanese especially in rural areas. The family responsibilities of
Sudanese women have greatly increased. Rates of malnutrition, infant and
maternal mortality and morbidity among the Sudanese, and in Southern families
overall are far above national averages. Food security and all basic services
are drastically weakened by the conflict. Women head about one in two
households in Southern Sudan.
Hence, the development of women industrial entrepreneurship is
a must to further the move towards rehabilitation and sustainability. This will
help women to increase and manage their incomes, promote food security and
develop childcare and maternal status; and hence, develop the well being of the
whole family.
UNIDO’s Cleaner Production and
Environmental Management Branch (SES/PEM) has established research linkages
promoting the conservation and use of under-utilized and neglected crops as
input to industry.
The plant “Jatropha Curcas” which is also
known as “Physic nut’ is from the family Euphorbiacae and traditionally the
plant is used as a wind-protector for farms and agricultural schemes in most
African Sub-Saharan rural areas. It can grow in arid and semi-arid soils that
are relatively poor, as far as fertility is concerned. This important character
makes the plant very useful in combating desertification (soil erosion control)
and it is also known to retain large amounts of water in its roots, branches
and stem for relatively long periods of draught. It naturally grows in most of
Sub-Saharan countries and easily adapting to tropical areas. The plant seed is
containing a high percentage of oil, 45-48% wet basis. It is not an edible oil
for either human or animal consumption, and therefore it could be used as a
good source of industrial raw material to substitute vegetable oils in
manufacturing industries such as soap making and paint industry.
The main aim
of the project is to support the establishment of a self sustaining project
model with an institutional base for reducing global warming, combating
desertification in the Sub-Saharan zone, enriching crop diversification in
rural agricultural areas in Africa and protecting the environment so as to
obtain a maximum benefit from a naturally growing plant to serve the welfare of
the community. This is through the development of the plant Jatropha which is
evaluated as a potential source of surge to the industrial vegetable oil usages
and also as a source of farming fuel. Institutional and human resource capacity
building will be emphasized through technical and applied multi-disciplinary
research.
In this
respect the programme/project is subdivided into two phases: pilot projects
phase and industrial large-scale phase. The pilot projects phase is containing
three major stages; agricultural activity that starts with establishing
farming schemes by cooperative groups in villages, namely with existing
community NGOs, industrial processing will be in a form of small oil
extraction unit to supply samples for testing the market vectors in different
industrial sub-sectors. It could be used as substitute to edible oils in soap,
detergents, cosmetics, leather, and textile and paint industry depending on the
degree of quality. Part of this oil will be used as a diesel fuel substitute in
the remote areas for water pumping, electricity generation, machine lubrication
and general agricultural purposes and in-farm utilization in the villages. The
residues of Jatropha plant in the form of cake will be used as natural
fertilizers and soil nitrogen fixers.
This will
provide employment to rural communities, stimulate the creation of small and
medium scale industries/enterprises and entrepreneurs, consolidate the effort
towards combating desertification, reducing carbon dioxide emissions and hence
reduction of global warming, enriching women development issues, reinforcing
poverty alleviation efforts and enhancing the standards of living.
The project
will receive GEF funding under “targeted research” for renewable energy, global
warming, land degradation, linkages through networking of research to
appropriate industries. The project is subdivided into two phases and the
present document is covering the activities of the first phase. At least
research institutions in six Africa sub-Saharan countries will be involved
(Kenya, Uganda, Sudan, Chad, Mali, Niger). Several international workshops and
seminars will be conducted during the course of implementation of the project.
2.1. Development Objective
The development
objective of the Project is to improve the socio-economic status of poor population in rural areas through the development of the Jatropha System
in the Sudan. The Jatropha system is an integrated approach with multi-purpose
objectives of environment protection, income generation, women promotion, jobs
creation, food security, and poverty alleviation that will lead therefore to
improving the socio-economic welfare of the rural population in the country.
2.1. Immediate

4. TARGET
BENEFICIARIES
The ultimate
objective of the Programme is to improve the socio-economic status of Sudanese
population through the development and promotion of the Jatropha System. To
that end, the primary target beneficiaries of the project will consist of:
§
Individual men and women who will be involved
in the project;
§
Women at the
areas of concern and families headed by those women;
§
Existing and potential entrepreneurs at the rural
areas of concern.
§
Public and
private sector support institutions including research, training and technical
support institutions providing services for entrepreneurs. Special emphasis will be placed on those
entities responsible for promoting the creation and
development of small-scale industrial enterprises; and
§
Relevant
national and regional government ministries responsible
for agricultural, industrial and rural development especially the Ministry of
Agriculture and Forests, Ministry of Higher Education, the Ministry of Science
and Technology, etc.
The secondary beneficiaries include:
§
The rural
population in the Sudan especially in the target areas;
§
Small-scale industrial enterprises in the
informal sector and particularly in rural areas; and
§
Private and public sector organizations and
community associations in the selected areas such as women groups, etc.
§
Public and private sector institutions providing technical,
financial and advisory services for entrepreneurs.
5. INSTITUTIONAL FRAMEWORK
The Project is expected
to help in building-up the local capacity for the development and promotion of
small-scale industrial enterprises in rural areas parallel to agricultural
activity. This will assist in the
development of activities aimed at helping the target beneficiaries to raise
their abilities, enhance their incomes, improve their welfare and, therefore,
alleviate poverty in a sustainable matter.
The institutional framework for the Project,
hence, envisages several public and private sector institutions to be involved
with the development of small-scale industries in Sudan and with capacity
building and skills development. To that end, it is essential that all
institutions interact with each other and evolve cohesive plans for the benefit
of the industrial sector and the economy.
For the implementation of this Project, the institutional framework
would include the following main
counterparts:
§
Academic
institutions e.g. University of Khartoum, Zalingi, Nihud, etc.
§
Research
institutions e.g. Industrial Research and Consultancy Centre
(IRCC), the National Centre for Research.
§
Relevant
government ministries e.g. Ministry of Agriculture and Forests, Ministry of
Science and Technology, etc.
§
Public and private
sector organizations e.g. Small Scale Industries and
Craftsmen Union; Management Development Centre;
§
NGOs e.g. Intermediate Technology Development Group (ITDG), Community Development
Association, etc.
§
Other
institutions would be involved for co-ordination purposes. These include the
GEF Focal Points at the UNDP and at the Ministry of International Cooperation;
and the Coordination Offices of the concerned States.
The possibility of utilizing the former UNDP Area Development
Schemes (ADS) would be examined, as it constitutes a well-established
institutional frame which already exists in those areas.
An agreement will be
signed by the GEF, the Government of the Sudan and UNIDO on the financing and
implementation of the Project. The
locations where such an intervention shall be undertaken are proposed
thereunder. The project will be executed by
UNIDO using national and international experts. In consultation with the
national authorities a focal point will be selected to liase with UNIDO. Consultations will also be held in the field
with multi-and bilateral agencies and relevant organization of the UN system
and NGOs, as appropriate. The project will also secure the widest possible participation
of other interested parties in the country, such as local donor agencies as
well as other relevant organizations.
The implementation of the project will be
carried out essentially by local experts in Sudan with the technical support of
a team of UNIDO Headquarters’ staff and internationally and locally recruited
experts. The Project team will therefore, require a national counterpart team
of qualified experts drawn from the relevant government ministries, support
institutions and the private sector.
Overall co-ordination of project activities in the field will
take place through a Steering Committee (SC) at the federal level. The SC will
provide technical advice and co-ordination at all phases of the project
implementation. The Steering Committee will consist of a selected number of
representatives of the main public and private sector organizations concerned.
The contracting of local experts and
procurement of equipment and sub-contractual services will be handled locally
in accordance with UNIDO rules and regulations through an authorization from
UNIDO Headquarters to the local UNDP and UNIDO Offices. Small items of office
equipment and supplies will, however, be handled locally through an
authorization from UNIDO Headquarters to the local UNDP and UNIDO Offices.
At UNIDO Headquarters, the implementation of the project would include
a multi-disciplinary team composed of the SES Branch, Private Sector
Development Branch, the Arab Countries Bureau, other relevant Technical
Branches, as may be required.
The main output of the Project will be improved socio-economic
status of the Sudanese especially in the selected areas. More specifically, the
outputs will consist of the following:
Ø
Minimization of
the adverse environmental impact, through promotion of Jatropha plantation;
Ø
Creation of job
opportunities for both women and men in rural areas;
Ø
Generation of
income for poor women in particular, and their families in general, hence
contributing to poverty alleviation in the selected regions;
Ø
Production of
many useful products from Jatropha oil e.g. soap, insecticide, etc.;
Ø
Enhancing the
skills of a number of men and women industrial entrepreneurs i.e. human
resources development;
Ø
Provision of
technical support for entrepreneurs including introduction and utilization of appropriate
technologies, marketing, etc.
Ø
Development and
promotion of small-scale industries
Ø
Food security;
Ø
The project may
generate foreign exchange from sales of Jatropha seeds, oil and oil
products to neighboring countries;
Ø
Increased
number of women encouraged to participate
in the project and improve their ability to manage their own small-scale
industries; and
Ø
Strengthening
of technical support institutions.
8. SUSTAINABILITY
Involvement of community in all aspects of
the project will enhance its sustainability through developing a sense of
ownership. All the produced products from the Jatropha plant will be sold by
the entrepreneurs themselves and all the outcome will return to them. This
would create an incentive and motivation for the rural population.
The Project would focus on the development and promotion of
small-scale industrial enterprises, enhancing the quality of their products as
well as of specific skills through pilot demonstrations and group training
activities, to upgrade skills at the enterprise level. This would, therefore,
largely contribute to sustainability of the project through development of a
core of skilled entrepreneurs.
At the institutional level the Project would, among others
things, provide for strengthening of the national technical support, academic
and research institutions.
PART C: APPROACH
AND FINDINGS
Based on the duties indicated in the Job Description (copy
attached as Annex I), the National expert undertook a survey to:
Ü
Learn about the
Jatropha curcas in Sudan
Ü
Collect
information on national research institutions that are involved in Jatropha
plant and/or similar plant development activities
Ü
Identify
potential counterpart institutions that could be involved in different phases
of project implementation. These include relevant universities, research
institutions and NGOs.
Ü
Contact the
Universities of Western Sudan (El Nuhud/Kordofan and Zalingy/Darfur) and
collect information on research projects for combating desertification and
possible inclusion of Jatropha plant.
The methodology used towards achieving the above, included
literature review, preliminary survey and consultations. Potential counterparts
were identified by the expert. Individual meetings were conducted, thereafter,
in order to inform the concerned national authorities about the project. Views
were exchange with various institutions on the project implementation. Copies
of technical papers and summary of research activities were gathered by the
expert.
Two group meetings were organized by the National Expert
(copies of the minutes of the meetings are included in the Annexes); the first
one was to introduce the concept of the project to the concerned national
authorities identified by the expert; and the later was to get their feedback.
The meetings were well-attended by a number of experts from various
institutions.
Some seeds (about 2 kg) were sent from UNIDO Headquarters for
preliminary research work. These seeds were distributed to some potential
counterparts for testing. For example, the Industrial Research and Consultancy
Centre (IRCC) conducted laboratory tests for extracting oil and analyzing its
physical and chemical properties. The
Desert Research Department at the National Centre for Research carried out some
research on planting the Jatropha at El Rawakeeb Research Station. The
Medicinal and Aromatic Plants Research Institute tested the toxicity of the oil
extracted from the seeds.
The directors of the University of Al Nuhud and University of
Zalinji were contacted and they expressed their interest and willingness to act
as counterparts during the project implementation. They expressed their
readiness to include research on development of Jatropha plant as part of their
research activities.
Copies
of technical papers and research documents, pertaining to relevant past
experience in the country, were collected from relevant institutions and their
summary was prepared.
The findings will be presented in the following chapters of
this report.
I. THE PLANT
1. THE JATROPHA PLANT IN
SUDAN
Hamza, 1990 in “Trees and Shrubs of Sudan” mentioned that the
Jatropha is known to be in Sudan in five different specie:
Found in Northern Sudan, Khor Ashat, Khor Gwob, and in the dry
savanna zone of the Red Sea Hills.
Introduced as a hedge plant in Kordofan,
White Nile, Bahr El Ghazal and Bahr El Jebel States.
Found in central Sudan
Found in Northern and Central Sudan.
Found in Northern Sudan between Suakin and
Kassala (Jebel Iskeneib).
However, according to Brown and Massey (1929), other species in
addition to those five exist in Sudan. These are:
Found in Equatoria State
Found in Bahr El Ghazal State ( Jur : Jur
Ghattas, Niamniam-land)
Found in Northern and Central Sudan.
Found in Red Sea State (Suakin ), Kordofan
State ( Katul Gumbara).
Found between Suakin & Kassala (J.
Iskeneib).
Found in Bahr El Jebel State (Madi)
Found in Bahr El Ghazal State ( Jur)

Arabic names: Habat
Almolouk, Khirwi Engilizi
Common names: Over 30
common names (e.g. Barbados-nut, FIKI, Physic nut). Exotic to 72 countries all
over the tropics
Habitat and Distribution:
The plant is Native of Latin America (8 countries). Some
information specified that it is originally from Brazil. Others are suspecting
that its center of origin is Mexico and Central America. The species was
probably distributed by Portuguese seafarers via the Cape Verde Islands and
former Portuguese Guinea (now Guinea Bissau) to other countries in Africa and
Asia. The species is almost pan tropical now, widely planted as a medicinal
plant. It is listed, e.g., as a weed in Brazil, Fiji, Honduras, India, Jamaica,
Panama, Puerto Rico, and Salvador (Holm et al, 1979). The plant is naturalized
and widely distributed throughout the tropics and southern United States.
Range
Africa, Bahamas, Bolivia, Brazil, Burkina Faso, Colombia,
Dominican Republic, El Salvador, Gabon, Gambia, Ghana, Guatemala, Haiti, Hawaii
Volcanoes National Park, India, Indonesia, Ivory Coast, Java, Malaya, Malaysia,
Mauritius, Mexico, Natal, Nigeria, Panama, Philippines, Samoa, Sudan, Tonga,
Trinidad, Venezuela.
The current distribution of Jatropha curcas shows that its
introduction has been most successful in dry regions of the tropics. As a
succulent that sheds its leaves during the dry season, J. curcas is best
adapted to arid and semi-arid conditions. It is very tolerant and thrives under
a wide range of climatic and edaphic conditions ranging from Tropical Very Dry
to Moist through Subtropical Thorn to Wet Forest Life Zone. Physic nut is
reported to tolerate annual precipitation of 4.8 to 23.8 dm (mean of 60 cases
=14.31). Jatropha curcas is highly adaptable species, and its strength as a
crop comes from its ability to grow on poor, dry sites. The plant is very
drought tolerant and can withstand slight frost. It could tolerate up to 4.8
months of complete drought. The plant is not sensitive to day length.
Altitude: The
plant could grow at high places up to 1000 m above sea level.
Mean annual rainfall: Jatropha is a tropical plant and its water requirements range
between 250-1000 mm.
Mean annual temperature: 20-28 oC or more.
Soil type:
The Jatropha plant is characterized by its ability to survive
in poor, stony soils that makes the plant usefulness for erosion control. It
grows on well-drained soils with good aeration and is well adapted to marginal
soils with low nutrient. On heavy soils, root formation is reduced.
Plant Description:
J. curcas is a
shrub or small tree well-known in tropical South America for its medicinal
properties and as an oilseed. It has been distributed to most tropical and
subtropical parts of the world. It could be a suitable crop for poor peasants
on marginal agricultural land since it requires few inputs. It is also
resistant to drought and not palatable to grazing animals.
Jatropha curcas
is a tender perennial, monoecious shrub or small
tree. The plant life is
about 50 years. It could grow up to 6 m high with
spreading branches. It grows readily in swamp or shade and is quick
growing. This shrub or small tree has large 3- to 5-parted alternate leaves. It
has small, off-white flowers and its greenish-yellow apple-sized fruits contain
three large black seeds. It has a pale brown
bark, peeling; slash exudes copious watery latex, soapy to tough but soon
becoming brittle and brownish when dry; branches glabrous, ascending, stout.
Leaves alternate, palmate, petiolate, stipules minutes; petiole
2-20 cm long, blade 3-5 lobed, 12.5 – 18 x 11-16 cm, lobe acute or shortly
acuminate at the apex, margins entire or undulating, leaf base deeply
cordatemglabrous or pubesdent only on the veins below, basal veins 7-9,
prominent, venation reticulate.
Inflorescent a cyne formed terminally on branches and complex,
possessing main and co-florescences with paracladia. The plant is monoecious
and flowers are unisexual; occasionally hermaphroditic flowers occur; 10
staemns arranged in 2 distinct whorls of 5 each in a single column in the
androecium and in close proximity to each other. In the gynaecium, the 3
slender styles are connate to about 2/3 of their length, dilating to a massive
bifurcate stigma. Female flowers with sepals up to 18 mm long, persisting ovary
3- locular, ellipsoid, 1.5-2 mm in diameter, style bifid.
Fruit is an ellipsoid capsule 2.503 cm long, 2-3 cm in
diameter, yellow, turning black. Seeds
black, 2 per cell, ellipsoid, triangle-convex, 1.5-2 x 1-1.1 cm.
Jatropha is an
impressive looking small tree cultivated as an ornamental throughout Africa.
Seeds and leaves have a strong purgative action and should not be used
internally as they are poisonous if taken internally. The plant cannot be used for food or fodder. The seeds are toxic.
They are used externally for skin parasites, venereal disease, herpes, and as a
dressing for wounds. The seeds contain a high percentage of oil that has
numerous uses such as candles, soap and bio-diesel production.
Hamza (1990) described the Jatropha curcas plant as a shrubs or
small trees up to 7 m high. Bark papery, peeling. Branches thick with viscid
sap, sometimes becoming red and gummy, yellow. Leaves 5- lobed or entire, ovate
rounded, about 8.5 cm long and broad, glabrous; petioles about 11 cm long.
Flowers yellow-green; stamens 8, inner connate; disk deeply 5- lobed. Fruit
scarcely lobed, ellipsoid capsules about 2.5 cm long, black; seeds 3. Flowers
April; and fruits May.
Action
Anodyne, antidote, cicatrizant, dentifrice, diuretic, emetic,
emollient, hemostat, lactogogue, laxative, narcotic, pesticide, purgative,
raticide, rubefacient, styptic, vermifuge.
J. curcas can be grown from seeds or cuttings (0.4-1 m long).
It grows readily and plants begin bearing at 4-5 months. Cuttings strike root
so easily that the plant can be used as an energy-producing living fence post.
The plant harvesting depends on the end use. For medicinal
purposes, the seeds are harvested as needed. For energy purposes, seeds might
be harvested all at once, the active medicinal compounds might be extracted
from the seed, before, or after the oil, leaving the oil cake for biomass or
manure. The plant productivity is about 6-8 tons per hectare.
Propagation,
Reproduction and Management:
The species is easily propagated by direct seeding,
pre-cultivation of seeding, transplanting of spontaneous wild plants and direct
planting of cuttings. Seed should be collected when capsules split open. Use of
fresh seeds improves germination. Intervals of presoaking and drying, or
partial removal of the rtesta are more successful than presoaking alone. With
good moisture conditions, germination takes 10 days. The seed shell splits, the
radicula emerges and 4 small peripheral roots are formed soon after development
of the first leaves. The cotyledons wither and fall off. Further growth is
sympodial.
Pollination is by insects. The rare hermaphroditic flowers can
be self-pollinating. After pollination the trilocular ellipsoid fruit is
formed, the exocarp remains fleshy until the seeds are mature. Fruit
development needs 90 days from flowering until seeds mature. Fruits ripen 4
months after flowering. In permanently humid equatorial regions, flowering
occurs throughout the year. Shrubs begin to produce at 4-5 months and reach
full productivity at about 3 years. The female flowers are 4-5 times more
numerous than the male ones.
Seedlings are susceptible to competition from weeds during
their early development. Therefore, weed control, either mechanical or with
herbicides, is required during the establishment phase. Satisfactory planting
widths are 2x2 m, 2.5x2.5 m and 3x3 m. This is equivalent to crop densities of
2500, 1600 and 1111 plants/ha, respectively. Under good rainfall conditions,
nursery plants bear fruit after the first rainy season, while directly seeded
plants bear for the first time after the second rainy season. With vegetative
propagation, the first seed yield higher. At least 2-3 tons of seeds/ha can be
achieved in semi-arid areas.
Live fences can be established quickly by planting cuttings
directly in the field. Pruning as a hedge is a frequent practice. Jatropha
curcas has a productive life of 40-50
years without necessitating replanting or tending.
Seeds are oily and do not store for long. Seeds older than 15
months show viability below 50%. High levels of viability and low levels of
germination shortly after harvest indicate innate (primary) dormancy.
seed yields approach 6-8 MT/ha with ca 37% oil. It is estimated
that such yields could produce the equivalent of 2,100-2,800 liters fuel
oil/ha. In Madagascar, for example, they have ca 10.000 ha of purging nut, each
producing ca 24 hl oil/ha for a potential production of 240,000 hl.
the following are affecting Jatropha curcas: Clitocybe tabescens
(roots rot), clletotrichum gloeosporiocides (leaf spot), and Phakopsora
jatrophicola (rust).
Some pests and diseases have been observed on J. curcas in
Senegal. In Zimbabwe, powdery mildew damages leaves and flowers, alternaria
causes premature leaf fall, and golden flea beetles eat young leaves and
shoots. In other countries pests and diseases do not cause sever problems
although millipedes can cause total loss of young seedlings. Jatropha curcas is
a host for cassava viruses.
Spodoptera litura (Fab.) Boursin (Lepidoptera: Noctuidae) is
reported as a pest of Jatropha curcas Linn. In India, Spodoptera Litura was
identified as a pest of Jatropha curcas.
Seed content
The seeds contain large amount of oil. In Brazil, chemical and
analysis of the seeds revealed a high protein content (26.75%) with a large
proportion of essential amino acids and high lipid content (57.90%).
Oil content
In Pakistan, the fixed oil ( 41.5%) from J. curcas seeds was
analyzed for its fatty acid composition and physicochemical properties. The oil
consisted of palmitic acid (14.16%), stearic acid (7.68%), oleic acid (46.72%)
and linoleic acid (30.31%). The physicochemical constants were: refractive
index at 30o , 1.4675; iodine value, 102; saponification value,
196.72; flash point, 227o C; and calorific value, 8990 kcal/kg.
In India, oil contents was analyzed and found to be rich in
oleic and linoleic acids.
Toxicity
Laboratory test showed that some toxic
materials exist in the plant oil. It was found that the toxicity of Jatropha
oil is higher than that of the castor oil. There are about 25 scientific papers
on the toxicity of Jatropha and its comparison with castor oil.
All parts of the physic nut are poisonous. Bark, fruits, leaf,
root, and wood are all reported to contain HCN. Seeds contains the dangerous
toxalbumin curcin, rending them potential fatally toxic. The seeds taste sweet
but their oil is violently purgative when eaten. The poisoning is irritant,
with acute abdominal pain and nausea about ½ hour following ingestion. Diarrhea
and nausea continue but are not usually serious. Depression and collapse may
occur, especially in children. Two seeds are strong purgative. Four to five
seed are said to have caused death, but the roasted seed is said to be nearly
innocuous.
the toxicity of J. curcas
seeds from Sudan (originally from Mexico) investigated in rats and mice. The
seeds of J. curcas have been reported to be toxic to mice, sheep and goats.
There was no toxicological effect but there was evidence of the presence of a
factor unpalatable to rats and mice which restricted food intake.
In University of Khartoum: Feeding J. curcas seed at 0.5% of
the basic diet to 9 male chicks (7 days old) for 2 weeks caused no deaths.
Nothing has been reported on the toxicity of the plants and its
impact on the farmers. Researchers stated that the seeds are toxic to rats and
sheep. In Italy , proteins extracted from seed of J. curcas were toxic
to mice. The crude protein and other protein fractions from both seeds
inhibited protein synthesis by a reticulocyte lysate.
Research is being conducted in Germany and Indonesia to reduce
the plant toxicity
J. curcas is traditionally used for medicine, pesticides,
cosmetics , industrial oils, and hedges.
Medicinal Uses
The plant is used as a medicine in treatment of more than 32
cases in different parts of the world.
Used to
Treat: anasarca, ascites, burns,
carbuncles, caries, cataplasm, circumcision, collapse, convulsions, cough,
dentition, depurative, diarrhea, dropsy, dysentery, eczema, empacho,
erysipelas, fever, gonorrhea, guinea worms, hernia, incontinence, itch,
jaundice, neuralgia, parturition, piles, pleurisy, pneumonia, rash, rheumatism,
roundworms, sore, sprains, stomach ache, syphilis, tetanus, thrush, toothache,
tumor, wounds, yaws, yellow fever .
Use: used for
enema, homicide, pesticide, raticide, medicine, mouthwash, poison.
In Suriname's traditional medicine, the leaves of physic nut
are used against stomachache diagnosed in children: boiled leaves for conditions
of the gums and throat; tea of the leaves for stoppage of urine, constipation,
and backache.
In Southern Sudan, the seed as well as the fruits is used as a
contraceptive.
Seeds were formerly exported from the Cape Verde Islands to
Portugal and the ‘curcas’, or purging oil, from them is a drastic purgative.
They resemble groundnuts in flavors, and 15-2 seeds will cause gripping,
purging and vomiting for 30 minutes. It is reported from Gabon that 1-2 roasted
seeds are sufficient to act as a purgative; larger doses may be dangerous. The
seeds have been substituted for castor oil and are sometimes called ‘larger
castor oil’. The oil is widely used for skin diseases and to soothe pain such
as that caused by rheumatism; it is an ingredient in the oily extract, known in
Hausa as ‘Kufi’, which is a rubifacient for rheumatism and for parasitic skin
conditions. The oil is used to stimulate hair growth. The seeds are also used
in the treatment of syphilis.
Juice or latex is
applied directly to wounds and cuts as a styptic and astringent to clean teeth, gums and to treat sores on the tongue
and in the mouth. Branches are used as a chewing stick in Nigeria. Latex has
antibiotic properties against Candida albicans, Escherichia coli, Klebsiella
pneumoniae, Staphylococcus aureus and Streptococcus pyogens. It also has
coagulating effects on blood plasma. A methanol extract of physic nut leaves
afforded moderate protection for cultural human lymphoblastoid cells against
the cytopathic effects of the human immunodeficiency virus.
Preparations of
the plant, including seeds, leaves and bark, fresh or as a decoction, are used
in traditional medicine and for veterinary purposes. A leaf infusion is used as
a diuretic, for bathing, to treat coughs and as an enema in treating convulsions
and fits. Leaves are also used to treat jaundice, fevers, rheumatic pains,
guinea worms sores and poor development of the fetus in pregnant women. The
leaves produce a sap that has haemostatic properties; it is used to dress
wounds. In Ghana the ashes from the burnt leaves are applied by rectal
injection for haemorrhoids. The root bark is used to relieve the spasms of
infantile tetanus and is used for sores, dysentery and jaundice. The juice of
the flowers has numerous medicinal qualities.
Food
The young leaves may be safely eaten, steamed or stewed” They
are favored for cooking with goat meat, said to counteract the peculiar smell.
Though purgative, the nuts are sometimes roasted and dangerously eaten. In
Guinea, ashes from the roots and branches are used as cooking salt. In other
areas. ashes of the burned root are used as a salt substitute. Young leaves may
be safely eaten when steamed or stewed. Cooked nuts are eaten in certain
regions of Mexico.
Renewable Energy Source
Jatropha oil is an environmentally safe, cost-effective
renewable source of non-conventional energy and a promising substitute for
diesel, kerosene and other fuels. Physic nut oil was used in engines in Segou,
Mali, during World War II. The oil burns without smoke and has been employed
for street lighting near Rio de Janeiro.
Fruit hulls and seed shells can be used as a fuel. Direct seeds
dipped into palm oil are used as torches, which will keep alight even in a
strong wind. The wood was used as fuel, though of poor quality, in Cape Verde.
In France the oil of J. curcas of Brazilian origin performed
well in diesel engines. the oil was used as a mixed fuel for diesel/gasoline
engines, in Pakistan,.
The clear oil expressed from the seed has been used for
illumination and lubricating, and more recently has been suggested for
energetic purposes, one ton of nuts yielding 70 kg refined petroleum, 40 kg
“gasoil leger” (light fuel oil), 40 kg regulator fuel oil, 34 kg dry
tar/pitch/rosin, 270 kg coke-like char, and 200 kg ammoniacal water, natural
gas, creosote, etc. In Malagasy, the following characteristics were reported on
Jatropha curcas:
Crop Production 6-8 MT/ha
Fuel Production 2,100-2,800/ha
Energetic equivalent 19,800-26,400 Kw/ha
In Mali; the oil obtained from the nuts of the physic nut bush
(Jatropha curcas) was used as a fuel in diesel engines.
In China, the characteristics of J. curcas (Sabu dum) oil were
enumerated and compared with those of diesel oil. Engine performance with J.
curcas oil was very good and there were no disadvantages to its use in place of
diesel oil.
In Thailand, the use of
J. curcas seed oil as a diesel substitute is known to have several
advantages for developing countries. The plant is easily grown in a wide
variety of soil types, including those in arid zones. The oil, even when
extracted by primitive processes without the use of modern expeller and without
any refining, can be used to replace diesel fluid in unmodified diesel engines.
In Burkina Faso, the potential of oil from seeds of J. curcas
as a diesel fuel substitute to promote
agricultural development in Burkina Faso was investigated. Trans-esterification
using ethyl alcohol has been applied to reduce oil viscosity and fuel
properties of the raw oil and esterified product 8 have been compared with
other seed oil and diesel fuels. Successful short-term experiments to determine
diesel engine performance showed that Jatropha oil ethyl ester produced 81% of
the max. power, 86% of the max. torgue and 115% of the specific fuel consumption
rate of diesel fuel No. 2. No distinction could be made between the superiority
of either Jatropha or rapeseed as alternate fuels.
In Japan, reported the application of plant oil Jatropha curcas
as a fuel for farm diesel engines. Performance (50 h- continuous) and starting
tests were conducted using transesterified curcas oil, No. 2 diesel fuel, and
their blends in 2 small precombustion chamber type diesel engines. 80 % blended
oil operated smoothly and was able to run for more than 50 hours continuously.
It produced superior thermal efficiency and fuel consumption equivalent to No.
2 diesel. There was a slight reduction in black smoke concentration when
operating on transesterified curcas oil and its blended oils. The same amount
of carbon deposit was observed in the cylinder head and pre-combustion chamber
as with diesel fuel. It was reported that the plant could be regarded as a
useful renewable fuel.
Poison
Curcas oil contains a toxin, curcasin. The albumen of the
kernel is a poison, toxalbumen cursin, most abundant in the embryo. Another
poison, a crton resin, occurs in the seeds and causes redness and pustular
eruptions of the skin. The plant is listed as fish poison. The bark is used in
some countries as a fish poison. Aqueous extracts of J. curcas leaves were
effective in controlling Sclerotium spp, an Azolla Fungal pathogen.
The seed oil, extracts of J. curcas seeds and phorbol esters
from the oil have been used to control various pests, often with successful
results. In Gabon, the seeds, ground and mixed with palm oil, are used to kill
rats. The oil has purgative properties, but seeds are poisonous; even remains
from pressed seeds can be fatal.
This poison also makes the plant an effective insecticide. Mexicans
grow the shrub as host for the lac insect. In India, pounded leaves are applied
near horses’ eyes to repel flies.
The plant is used as an anti-snail and as a moluscicide. It has
strong molluscicidal activity. In Sudan, the plant was used for Bilharzias
control. In Philippines, studies on the control of snail vectors of
fascioliasis; molluscicidal activity of some indigenous plants were conducted.
Out of 150 indigenous plants only seven, including the J. curcas, possessed
strong molluscicidal activity. It was used in India for the mosquito larvae.
Research on the anti-bacterial effect of Jatropha curcas was
conducted in Sudan.
In India, the latex was strongly inhibitory to watermelon
mosaic virus, which makes the plant a good anti-virus .
Further possibilities for utilizing the plant:
q
Tanning of
dyestuff: Leaf juice stains red and marks linen an
indelible black. The 37% tannin found in bark is said to yield a dark blue dye;
latex also contains 10% tannin and can be used as marking ink. Ashes from the
roots and branches are used in the dyeing industry, and pounded seeds in tannin
in Ghana.
q
Lipids: The seeds yield up to 31-37% of valuable
oil. It is used to prepare varnish after calcination with iron oxides. Hardened physic nut oil could
be a satisfactory substitute for tallow or hardened rice bran oil. In Europe it
is used in wool spinning and textile manufacture.
q
Soap: Due to its lipid content, the oil has been
used for soap making. Along with burnt plantain ashes, oil is used in making
hard homemade soap.
q
Wax: The bark contains a wax composed of a
mixture of ‘melissyl alcohol’ and its melissimic acid ester.
q
Erosion
control: Jatropha could
be used as a windbreak, anti-erosion barrier. in Cape Verde, J. curcas was
recently planted in arid areas for soil-erosion control.
q
Boundary or
barrier or support: Widely
cultivated in the tropics as a living fence in fields and settlements. Jatropha
curcas is not browsed by cattle; it can grow without protection and can be used
as a hedge to protect fields. Physic nut bushes are grown in Mali to make
hedges to protect fields from erosion and damage by animals.
q
Nitrogen Fixing
and Soil improver: Press cake
cannot be used in animal feed because of its toxic properties, but it is
valuable as organic manure due to nitrogen content similar to that of seed cake
from castor bean and chicken manure. The nitrogen content ranges from 3.2 to
3.8% depending on the source. Tender branches and leaves are used as a green
manure for coconut trees. All plant parts can be used as a green manure.
q
Intercropping: Integration of J. curcas into existing
cropping systems would improve the soil fertility. In Madagascar, the plant is
used as a support for vanilla.
q
Lightening: The oil has been used for illumination,
and candles making. Nuts can be strung on grass and burned like candlenuts.
3. JATROPHA CURCAS L. IN
SUDAN
The result of the survey and the two meetings as well as
individual meetings conducted by the national expert had given a fair insight
into the history of this plant. It is worthwhile giving hereunder the major
findings of the above- mentioned survey:
q
It was found
that research in Jatropha as an anti-desertification plant was not conducted by
any institution in Sudan. However, the Jatropha plant was known to be one of
the indigenous plants in Sudan that exists before the fifties. It grows
naturally and therefore exists as a wild plant. It was also introduced as a
hedge plant to many areas in Sudan such as Khartoum, Kassala, White Nile, Upper
White Nile, Bahr El Ghazal and Bahr El Jebel, Equatoria and Kordofan States.
q
It was listed in the (Trees and Shrubs of the
Sudan) and in (Flowering Plants of the Sudan) books. It was stated that 9
different species of the Jatropha exist in different areas of Sudan.
q
There is a
sample of the plant at the Medicinal and Aromatic Plants Research Institute,
National Centre for Research.
q
The idea of
utilizing Jatropha was initiated and introduced to Sudan in the early nineties
by institutions in India and Pakistan
q
The plant was
used as a hedge by the Horticulture Administration at the Ministry of
Agriculture and Forests.
q
A project was
carried out in Bara area at Kordofan State to introduce the Jatropha curcas.
However, the project was stopped due to some problems.
q
There is
information on the use of the plant as an insecticide.
q
The plant is
known as a member of the family of toxic plants
q
Information on
plant oil characteristics and methods of oil extraction is available at the
Industrial Research and Consultancy Centre (IRCC). Information on the
applications and uses of the oil is also available.
q
Some research
studies were conducted on the plant in Sudan e.g. there are two postgraduate
students (Ph.D. and M.Sc.) carried out research on Jatropha.
q
The use of
Jatropha curcas as an insecticide was investigated by a researcher at the
Medicinal and Aromatic Plants Research Institute. Another research was
conducted earlier on utilizing Jatropha curcas as a moulscicidal against
Bilharzias snails in Kassala area at Eastern Sudan.
q
It was stated
in the Database of the Documentation and Information Centre at the National
Centre of Research that Jatropha plant was traditionally used as a
contraceptive in Southern Sudan. An institution in UK conducted research in
1969 on toxicity of plant seeds that were brought from Southern Sudan. The
seeds were also examined as a traditional medicine
q
In 1984, the
Tropical Development Research Institute in UK investigated the toxicity of J.
curcas seeds from Sudan (originally from Mexico) to rats and mice. The seeds of
J. curcas have been reported to be toxic to mice, sheep and goats. There was no
toxicological effect but there was evidence of the presence of a factor
unpalatable to rats and mice which restricted food intake. At the University of
Khartoum : Feeding J. curcas seed at 0.5% of the basic diet to 9 male chicks (7
days old) for 2 weeks caused no deaths.
q
In 1990, a
student called Samia Al Badawi conducted her M.Sc. research on Jatropha.
q
Another student
called Howida conducted a research on the use of the plant as a pesticide.
q
A Sudanese
researcher was reported to carry out some research on the Jatropha plant in the
sixties.
q
In 1996, Mr.
Hafiz El Obied, a researcher at the Department of Desert Research, Environment
and Natural Resources Research Institute conducted a research to investigate
the plant tolerance to drought compared to other plants in Al Rawakeeb Research
Station near Omdurman. The seeds of the Jatropha curcas were brought from Mali.
It was observed that the plant showed superior growth and survival as compared
to other plants in the area. The germination of the plant took place in about
4-6 days while it was stated in the literature that the germination period is
ten days. The experiment was not sustainable due to a severe problem in the
pump at that time and due to lack of follow-up.
q
There are many
past experiences in Sudan carried out to combat desertification and to minimize
soil erosion and at the same utilizing the economic value of the plant. Similar
plant development activities were experienced by the development of such plants
as Prosopis (misquite), Lucinia and Hohoba (Jojoba).
q
The most
affected areas by desertification are those, which are lying between latitude
10-18 North. In this belt the extent of desertification is ranging from very
severe to severe with some vulnerable areas at risk of desertification in
addition to the Northern State. These include North Darfur, West Darfur, North
Kordofan and West Kordofan States. The soil texture in these areas is dominated
by sandy soil. It is therefore, recommended to plant the Jatropha at the margin
between decertified areas and areas at risk of desertification. This would
protect the later from wind and soil erosion and therefore, minimize
desertification impact.
q
The community
in Western Sudan would like to observe the benefits and return of the project.
The economic output from various industrial activities e.g. from oil
extraction, soap manufacturing and use of the oil as lubricant would convince
the community to join the project.
q
Similar project
was executed by GTZ in Mali.
q
The Jatropha curcas has
many applications in traditional medicine such as its use as anti-snail against
Bilharzias larvae. Currently, research is being taken by Japanese on the use of
Jatropha curcas in HIV/AIDS. Preliminary investigations showed good results but
it is not yet published. The seeds of the plant were reported to have an
antibacterial effect. There is information indicating that the leaves could be
used against Malaria. The oil was also used in some areas as a laxative for
treatment of constipation.
q
There are many researches
on the use of the plant oil as substitute to diesel and lubricant oil.
Currently the Volkswagen Co. is conducting research on the use of the plant in
its cars. Rockfiller Co. is doing research on the plant as a renewable energy
source.

JATROPHA CURCAS L. (Family Euphorbiaceae),
a poisonous plant which is widely grown in the Southern Region of the Sudan. It
was investigated for molluiscicidal activity against the snail BULINUS
TRANCATUSCS; and was found to exhibit low toxicity. Phytochemical screening
tests were conducted; alkaloids, saponins and sterols and/or triterpenes were
detected in the different morphological parts of the plant, whilst tannins were
found in the leaves and seeds only. The plant was found to be devoid of
glycosides ( Cyanogenic), Anthraquine or Cardenolide). Isolation of pure alkaloid from the seed was
not successful but a number of other compounds were isolated using two
different methods of extractions: Acetone-alcohol extract yield four compounds.
Ac/Et-I (18 H34 03), Ac/Et-11 (C30 H54 05). Ac/Et-111 (C18 H36 02) and Ac/Et-IV
(C18 H35 OH); Chloroform extract of defatted seed yielded; SO2-A) C16 H32 02),
SC2-B C24 H41 04) and SC3 SC2-B afforded an alcohol identified as diacetone
alcohol (C 6 H 12 02). However, exact structures remain to be settled.
the Jatropha System is
a multi-purpose approach that covers the following aspects in an
integrated project:
F
desertification
Control
by planting Jatropha as a hedge it helps
to minimize desertification through erosion control. The wide leaves of the
plant protects against wind while the lateral roots protects against water
erosion.
F
Rural
development
The Jatropha system involves the use of
village technology which is available and accessable and which does not require
big investment.
F
Income
generation
through development of small-scale
industrial enterprises such as utilizing the plant oil as raw material for soap
making which even does not require heating
unlike animal oil.
F
Women promotion
Through income-generating activities, the
Jatropha system helps to raise living standards of women. Additional source of
income could be created by planting Jatropha as a hedge
F
Food security
Planting Jatropha around farms and
agricultural fields protects food crops from invading animals and erosion. The
press cake could also be used as a high nitrogen content long-lasting natural
fertilizer.
F
Renewable
energy
The Jatropha oil could be used a diesel
substitute in water pumps, electric generators, etc.. The oil could also be
used for lightening by manufacturing a simple lamp which does not produce smoke
nor smell unlike the diesel lamb.
F
Medicinal Use
The plant is traditionally used for the
treatment of stomachache and rheumatism. Furthermore, the plant oil contains a
poison which could be extracted and utilized for medicinal uses e.g.
insecticide, against moulliscicide.
F
Reduce burden
on women
The Jatropha system would help in reducing
burden on women in rural areas. Normally women walk for long distance to
collect firewood. By making use of the plant oil in a simple cooker which could
be manufactured locally. Minimize handwork by using of equipment utilizing oil
as a substitute to diesel.

7. PROPOSED LOCATIONS FOR
PROJECT INTERVENTION
The main objective of the Project is to utilize the plant in
minimizing adverse environmental conditions e.g. sand storms and soil erosion.
The most affected areas by desertification are those, which are lying between
latitude 10-18 North. In this belt the extent of desertification is ranging
from very severe to severe with some vulnerable areas at risk of desertification
in addition to the Northern State. These include North Darfur, West Darfur,
North Kordofan and West Kordofan States. The Northern State is a desert area
frequently experiencing total absence of rain for yeas at a time. The situation
in North Darfur and North Kordofan States is relatively similar to that of the
Northern State. Putting into consideration the water requirements for the
plant, it is recommended that Jatropha would be planted in the margin between
decertified areas and areas at risk of desertification. This would protect the
later from wind and soil erosion and therefore, minimize desertification
impact. Therefore, West Darfur and West Kordofan States would be the best
location for that purpose.
Furthermore, it is proposed to plant Jatropha along the Nile in
the Northern State. This would have a dual impact; protecting the farms located
around the Nile from wind erosion and sand storms, and, at the same time,
utilizing the oil extracted from the plant as substitute for diesel to run the
water pumps.
It is also envisaged to plant Jatropha as a hedge to protect
farms and agricultural schemes from soil erosion and animals’ invasion. Other
proposed locations are around water sources e.g. wells, haffirs, fola, etc.
Why Western Sudan?
The most affected areas by desertification are those, which are
lying between latitude 10-18 North. In this belt the extent of desertification
is ranging from very severe to severe with some vulnerable areas at risk of
desertification in addition to the Northern State. These include North Darfur,
West Darfur, North Kordofan and West Kordofan States. The soil texture in these
areas is dominated by sandy soil. It is therefore, recommended to plant the
Jatropha at the margin between decertified areas and areas at risk of
desertification. This would protect the later from wind and soil erosion and
therefore, minimize desertification impact.
Western Sudan includes Northern Kordofan, Southern Kordofan,
and Western Kordofan States in addition to Northern Darfur, Southern Darfur and
Western Darfur States. Its latitudes
extend from 9.5o N and 19.0o N. Their western extremity
is at longitude 21.75o E and in the east is in longitude 32.0o
E. The area is about 876900 km2 (34%
of the area of the Sudan). More than 60% of the population are rural, settle in
small villages scattered all over the area. The main occupations are
agriculture and grazing. Nomads made about 24 % of the total population of
Western Sudan. The ecological zones in Western Sudan are classified according to
the rainfall characteristics into: desert, semi-desert and low rainfall savanna
woodland.
Western Sudan is
currently facing a severe drought and large quantities of food relief are being
air lifted to avoid a catastrophic human disaster. Agricultural productivity is
extremely low. The reduced production of dura, sesame, millet and dominance of
less palatable grasses, as well as the extinction of wildlife, are all strong
indicators of the seriousness of the problem. The Western Sudan is of
considerable importance to the Sudan’s economy. It is ecologically vulnerable
and has been exposed to recent desertification with very serious biological,
social and financial losses. For these and other reasons, it is envisaged to
focus on Western Sudan as the major proposed location for intervention.
II. SIMILAR PLANT
DEVELOPMENT ACTIVITIES
§
The Jojoba
Plant
The most similar plant development activity was carried out by
developing of the Jojoba Plant. The plant was initially utilized as an
alternative to oil in 1973 after the oil crisis resulted from the oil pan. It
was growing as a wild plant in Arizona desert in USA. Samples of the plant were
analyzed in Riverside University in California State. Thereafter, the plant was
introduced in Sudan in 1977 in Arkaweet and Bara. The project was funded by
UNDP and was implemented in collaboration with the Horticulture Administration
at the Ministry of Agriculture and University of California. It was later
planted in the areas of Sag Al Niam, Wadi Al Rawakeeb, Dongola and Kassala. The
project was implemented from 1977 to 1981. The results were highly praising in
Arkaweet and Bara. The plant flowered in 2-3 years as compared to 7 years in
the States. In Bara area the size of the seeds was double its normal size. In
1986, the project was expanded to become a regional project covering 10 other
countries from West Africa and Gulf region. The plant now exists in Arkaweet
area in Eastern Sudan. The trees are 34 years old. The trees were not irrigated
since 1986 and are still surviving drought. One thousand trees could be planted
per feddan. The productivity was 0.5 ton per feddan though was not irrigated.
This shows that the plant is an anti-desertification plant. In addition, the
plant has a considerable economic return as one ton of seeds is worth about US$
5000 and one ton of oil is about US$ 9000. The oil content is 50% of seeds
weight. The oil could be extracted by simple traditional methods. The oil has many applications in industry such
as lubricant oil in automobiles (cars), raw material in candles, cosmetics,
soap and aromatics. The cake could be utilized as animal fodder as it contains
30 5 protein. However it contains some toxic materials that should be treated
normally by simple fermentation and drying prior to its use.
The tree age is between
100-150 years and could reach up to 3 m height. The project failed due to
mismanagement and lack of coordination and cooperation among counterparts. It
should be managed by an organization not by farmers as it is a big project and
the return is after 3 years. The kilo of Jojoba seeds is worth about US$ 4.5.
There is an agreement between Sudan and the Association of the Farmers and
Manufacturers of Jojoba in the US, it could buy the seeds but in a bulk not
less than 15 tons. . There is a need of
a UN Agency to work closely with a scientific institution to took over and
supervise the project.
Further information on this plant is presented in the Annexes.
§
There are many past experiences in Sudan carried
out to combat desertification and to minimize soil erosion and at the same
utilizing the economic value of the plant. Similar plant development activities
were experienced by the development of such plants as Prosopis chilensis
(Mesquite), Acacia
mellifera (kitir) and Lucinia.
§
Other successful experiences were carried out by
the Forest National Corporation, SOS-
Sahel, Sudanese Social Forestry Society, etc.
§
Other similar
plant utilization experience was executed by the Industrial Research and
Consultancy Centre (IRCC) in utilizing the fruits of the traditional Laloab
tree (Balanites aegyptica) in industrial uses. The work included extraction of
the oil, analysis of oil characteristics, cake analysis, etc.
§
Experience with
other plants development include utilization of the Azadirachta indica (Neem
tree).
§
Experience in
oil extraction, medicinal and other applications of plant and plant oil are
revealed in chapter of potential counterpart institutions.

1.1.
Medicinal and Aromatic Plants Research Institute (MAPRI)
Background
Sudan had witnessed the fusion of various cultures along with
the local indigenous cultures. With unique history and vast variety of climate,
terrain, fauna, and flora, the people of Sudan have developed their own unique
