1. jatropha in gambia
December 12, 2007 THE PROMOTION OF GROWING JATROPHA IS GOING WELL Posted by jatrophagambia under 1, Help needed, Press No Comments Over the last weeks so much has happened that I don’t know where to start. The exhibition was a big success, there ware so many positive reactions that even our own ambassadors were kind of surprised about it, but also again convinced that they are putting all this energy in a good future for their country. At the exhibition we received an invitation for the 9-days Trade Fair. The EU had a table for the Jatropha project reserved, normal this would costs D 15,000, to be able to promote the growing of Jatropha in Gambia. We were so happy about this. The fair was an even bigger success. The Vice-President stopped at the Jatropha table for more then 10 minutes and this is special knowing that the other stands only had 1 minute of her time. She asked so many questions to Mr. Seedy Jarju (tel: +220.9701062) and Mr. Musa Samura (Tel: + 220.9980795 or 7331307) and she was so interested in the information that she even decided to come back after seeing some of the other stands. Radio and television interviewed our Seedy and Musa and they also promised to follow it up. At first all people are a bit reluctant. They all know the plant and they are all so surprised learning about the benefits and the possibilities it can give for the country. NGO’s are interested to support, schools are told to fence their school ground with Tabanane. Many people took seeds home for their own garden etc, etc. Mr. Seesy couldn’t stop talking and telling me how happy he was with all the positive feedback. I will post the letter with the report after the GREC exhibition and the Report after the fair here. But also we would like to thank Pierre again for bringing the information to us. Without him this would not all have happened. Thank you Pierre!! The next step is now to have the Jatropha initiative registered as a Charity organisation so they are able to receive sponsoring for the costs for copies, travel expenses, oil press production and the devellopment of cooking stoves etc.

2. JATROPHA IN AFRICA
Jatropha curcus is unusual among tree crops.
Perhaps its most unusual feature is its modular construction. The dry fruits and seeds will remain on the tree for some time, before falling to the ground, especially under dry conditions. Benefits include but are not limited to:
Oil as raw material: Oil has a very high Saponification value and is being extensively used for making soap in some countries. Also, the oil is used as an illuminant as it burns without emitting smoke.
Medicinal plant: The latex of Jatropha curcas (VanaErand or RatanJyot) contains an alkaloid known as "jatrophine" which is believed to have anti-cancerous properties.
Raw material for dye: The bark of Jatropha curcas (VanaErand or RatanJyot) yields a dark blue dye which is used for colouring cloth, fishing nets and lines.
Soil enrichment: Jatropha curcas (VanaErand or RatanJyot) oil cake is rich in nitrogen, phosphorous and potassium and can be used as organic manure.
Feed: Jatropha leaves are used as food for the tusser silkworm.
In addition to these benefits, scientists at Perdue University in the U.S. and elsewhere are working in the extraction of usable pharmaceutical derivatives from Jatropha Curcas while others are attempting to grow non-toxic plants (Mexico).
Preliminary research indicates Jatropha may display certain Anti-Tumor properties, Anti Malarial properties and research is advancing related to HIV/AIDÒs and immune system response enhancement. There are other levels of use that can be exploited. Direct fermentation of seed cake and pulp delivers an organic fertilizer that has a high potential for export to developed countries.
It is in the field of Bio Diesel fuel, however, that Jatropha's properties are the most exciting. At same power output, Jatropha curcas oil specific consumption and efficiencies are higher than those of diesel fuel. Tests conducted show that out of these various vegetable oils including copra, palm, groundnut, cottonseed, rapeseed, soya and sunflower - the lowest exhaust gas emissions were obtained with copra and Jatropha Curcas crude oil.
Over 50% of Africa's land has the
right climate for growing Jatropha
HOW MUCH LAND IN AFRICA IS SUITABLE FOR GROWING JATROPHA?
In a survey conducted by Dr. Guy Midgley, Chief Specialist Scientist of the Kirstenbosch Research Center of of the South African National Biodiversity Institute (Cape Town) over 1,080 million hectares land Africa could be termed prime growing regions for Jatropha Curcas on the African continent. A further 580 million hectares could be used making a total of 1,660 million hectares suitable for the growing of Jatropha Curcas.
On the map of Africa the dark areas represent prime Jatropha growing regions in Africa. These areas, comprising over 1,080 million hectares, or 10.8 million square kilometers, are ideal because the average annual rainfall exceeds 800 mm, and the minimum temperature of the coldest month is greater than 2 degrees centigrade.
The light green areas of the map are areas with average annual rainfall in excess of 300 mm, with the minimum temperature of the coldest month greater than 2 degrees centigrade. These areas, comprising over 580 million hectares, or 5.8 million square kilometers, are also viable regions for growing Jatropha.
HOW MUCH REVENUE PER HECTARE CAN JATROPHA GENERATE PER YEAR?
Over 50% of Africa's land has the
right climate for growing Jatropha
Referring to the table, the yield per hectare per year is up to 8.0 tons of Jatropha seed, which contain over 30% oil. At $320 (US$) per ton, this will translate into sales of Jatropha crude oil of $768 per hectare per year. Of potentially equal or greater value is the yield from Jatropha seeds of glycerin. Up to 7% of Jatropha seeds are made up of glycerin, which sells for up to $2,000 per ton. This translates into glycerin sales of up to $1,120 per year per hectare, or total sales of up to $1,888 per year per hectare.
Imagine, if only 3% of the land in Africa that is considered viable land to grow Jatropha was actually planted with Jatropha, with a yield of 8 tons per hectare per year and an oil content of 30% some 119 Million tons of Jatropha crude oil would be produced per year. The glycerin content at 7% of the 119 M tons would produce an additional 8.366 M tons. Glycerin is indeed a valuable by product.
In terms of annual revenues, if only 3% of the potential Jatropha growing regions in Africa were planted with Jatropha, based on a Jatropha crude oil price of $320 per ton and with glycerin selling at $2000 per ton a total sales value of $55 billion per year would be generated. Processing the crude oil into Bio Diesel would on average in Africa add a further 15% to the sales value. This sales value excludes other byproducts of Jatropha. Most African countries are oil dependent and foreign exchange expenditure would be reduced.
Jatropha farming could be an incredible contribution to economic development in Africa. Feasibility however is problematic due to the difficulty sourcing suitable financing. The two main reasons for failures to source funding are:
1) Land in many countries in Africa is not owned but leased. This effectively eliminates land being used as collateral by funders.
2) Start up agriculture projects are generally among the most difficult projects for which to obtain funding.
Moreover, financial models show that an assured supply of feed stock is required from a central area to ensure a viable project. Only when this is assured can out growers be considered to supplement the main supply chain. Projects where only marginal land is to be used will be very border line and unlikely to financially succeed. Good yields on marginal land are highly unlikely to be obtained.

3. JATROPHA PLANTATION
JATROPHA PLANTATION
Jatropha may be the answer
FOR FUTURE FUEL
INTRODUCTION
Jatropha curcus is a drought-resistant perennial, growing well in marginal/poor soil. It is easy to establish, grows relatively quickly and lives, producing seeds for 50 years.
Jatropha the wonder plant produces seeds with an oil content of 37%. The oil can be combusted as fuel without being refined. It burns with clear smoke-free flame, tested successfully as fuel for simple diesel engine. The by-products are press cake a good organic fertilizer, oil contains also insecticide.
It is found to be growing in many parts of the country, rugged in nature and can survive with minimum inputs and easy to propagate.
Medically it is used for diseases like cancer, piles, snakebite, paralysis, dropsy etc.
Jatropha grows wild in many areas of India and even thrives on infertile soil. A good crop can be obtained with little effort. Depending on soil quality and rainfall, oil can be extracted from the jatropha nuts after two to five years. The annual nut yield ranges from 0.5 to 12 tons. The kernels consist of oil to about 60 percent; this can be transformed into biodiesel fuel through esterification.
Family: Euphorbiaceae Synonyms: Curcas purgans Medic. Vernacular/common names: English- physic nut, purging nut; Hindi - Ratanjyot Jangli erandi; Malayalam – Katamanak; Tamil – Kattamanakku; Telugu – Pepalam; Kannada – Kadaharalu; Gujarathi – Jepal; Sanskrit – Kanana randa.
Distribution and habitat
It is still uncertain where the centre of origin is, but it is believed to be Mexico and Central America. It has been introduced to Africa and Asia and is now culti-vated world-wide. This highly drought-resistant spe-cies is adapted to arid and semi-arid conditions. The current distribution shows that introduction has been most successful in the drier regions of the tropics with annual rainfall of 300-1000 mm. It occurs mainly at lower altitudes (0-500 m) in areas with average an-nual temperatures well above 20°C but can grow at higher altitudes and tolerates slight frost. It grows on well-drained soils with good aeration and is well adapted to marginal soils with low nutrient content.
Botanical Features
It is a small tree or shrub with smooth gray bark, which exudes a whitish colored, watery, latex when cut. Normally, it grows between three and five meters in height, but can attain a height of up to eight or ten meters under favourable conditions.
Leaves
It has large green to pale-green leaves, alternate to sub-opposite, three-to five-lobed with a spiral phyllotaxis.
Flowers
The petiole length ranges between 6-23 mm. The inflorescence is formed in the leaf axil. Flowers are formed terminally, individually, with female flowers usually slightly larger and occurs in the hot seasons. In conditions where continuous growth occurs, an unbalance of pistillate or staminate flower production results in a higher number of female flowers.
Fruits
Fruits are produced in winter when the shrub is leafless, or it may produce several crops during the year if soil moisture is good and temperatures are sufficiently high. Each inflorescence yields a bunch of approximately 10 or more ovoid fruits. A three, bi-valved cocci is formed after the seeds mature and the fleshy exocarp dries.
Seeds
The seeds become mature when the capsule changes from green to yellow, after two to four months from
Flowering and fruiting habit
The trees are deciduous, shedding the leaves in the dry season. Flowering occurs during the wet season and two flowering peaks are often seen. In permanently hu-mid regions, flowering occurs throughout the year. The seeds mature about three months after flowering. Early growth is fast and with good rainfall conditions nursery plants may bear fruits after the first rainy season, direct sown plants after the second rainy season. The flowers are pollinated by insects especially honey bees.
2.Ecological Requirements
Jatropha curcas grows almost anywhere – even on gravelly, sandy and saline soils. It can thrive on the poorest stony soil. It can grow even in the crevices of rocks. The leaves shed during the winter months form mulch around the base of the plant. The organic matter from shed leaves enhance earth-worm activity in the soil around the root-zone of the plants, which improves the fertility of the soil.
Regarding climate, Jatropha curcas is found in the tropics and subtropics and likes heat, although it does well even in lower temperatures and can withstand a light frost. Its water requirement is extremely low and it can stand long periods of drought by shedding most of its leaves to reduce transpiration loss. Jatropha is also suitable for preventing soil erosion and shifting of sand dunes.
Biophysical limits
Altitude: 0-500 m, Mean annual temperature: 20-28 deg. C, Mean annual rainfall: 300-1000 mm or more.
Soil type: Grows on well-drained soils with good aeration and is well adapted to marginal soils with low nutrient content. On heavy soils, root formation is reduced. Jatropha is a highly adaptable species, but its strength as a crop comes from its ability to grow on very poor and dry sites

4. mijn kontakt in gambia
midden oktober vroeg een nederlandse vrouw beppie smits of ik een link op mijn website wilde zetten.wat ik deed! daarna vroeg ik haar of ze iets afwist van jatropha in gambia.ik gaf haar wat links vroeg of ze deze wilde lezen en daarna kontakt met me opnemen.ze deed dit en nog meer ze ging op zoek naar zaden perste deze uit
probeerde de olie en het vlammetje brandde letterlijk en figuurlijk.ze ging ook takjes van de boom "stekken" met als resultaat dat ze nu al een flink aantal planten heeft van zo een 50 cm groot.goed om uit te planten in juni.
maar ze deed nog meer ze vroeg meer info en ging opzoek op het internet met als gevolg dat ze momenteel heel gambia aan het bekeren is tot het aanplanten van jatropha!
dit alles terwijl ze de drijvende kracht is van een generatoren bedrijf tesamen met haar man milko berben.beppie's websites zijn

bio diesel in gambia
Pierre Vanderbeuken uit Nieuwerkerken maakt biobrandstof in Gambia. Limburger produceert biobrandstof in Gambia NIEUWERKERKEN - Pierre Vanderbeuken, een postbode uit Nieuwerkerken, spoort landbouwers in Gambia aan om op een ecologisch verantwoorde en duurzame manier brandstof te produceren. De olie van de Jatropha Curcasplant wordt al langer gebruikt voor tal van medicinale toepassingen, maar heeft pas recent een tweede leven gekregen als brandstof voor dieselmotoren. Vanderbeuken reist al ruim tien jaar tot vier keer per jaar naar Gambia. Zijn liefde voor het land en de bekommernis om de situatie van zijn inwoners is in de loop der jaren uitgegroeid tot een uit de hand gelopen passie. In het verleden verscheepte de Nieuwerkerkenaar al honderden trapnaaimachines en onlangs nog een röntgenapparaat naar het West- Afrikaanse land met goed anderhalf miljoen inwoners. ,,De plannen om in België koolzaad als alternatief voor fossiele brandstof te gebruiken, hebben me op het idee gebracht om in Gambia een gelijkaardig initiatief op te starten. De Jatrophaplant groeit in bijna heel Afrika in het wild en wordt vaak gebruikt als haag. Ook worden de vruchten gebruikt voor de Marseillezeep. Maar de noot van de plant bevat ongeveer 33 procent olie. En die kan zonder aanpassingen gebruikt worden als brandstof om dieselmotoren aan te drijven of elektriciteit op te wekken. Op die manier kan een halt toegeroepen worden aan de boomkap in Gambia'', zegt Vanderbeuken. Weinig onderhoud Het grote voordeel van de Jatrophaplant is dat ze amper onderhoud nodig heeft. Eén perceel van een hectare is jaarlijks goed voor vierduizend liter olie. Van één enkele aanplanting kan je vijftig jaar lang oogsten en iedere plant heeft jaarlijks niet meer dan één glas water nodig. ,,In India rijden op dit moment al diesellocomotieven op de Jatropha-olie en zelfs in de woestijn in Egypte wordt op dit moment geëxperimenteerd met de aanplanting van de boompjes. In Gambia ontbreekt het de landbouwers voorlopig aan de knowhow om zelf met plantages te beginnen. Maar ik onderhoud goede contacten met de overheid en probeer zoveel mogelijk Gambianen van het voordeel van de Jatrophaplanten te overtuigen. Wel blijft het opletten dat niet teveel goede landbouwgrond verloren gaat voor de olieplanten'', meent Vanderbeuken. Een introductie van de Afrikaanse planten in ons land dicht de Nieuwerkerkenaar weinig kansen toe. ,,De plant verdraagt absoluut geen koude temperaturen. En kweken in een serre is ook al geen optie omdat de stookkosten hoger zouden zijn dan de opbrengst'', zegt hij. Vanderbeuken heeft alvast wel Toon Hermans, de Hasseltse schepen voor Ontwikkelingssamenwerking (Groen!), kunnen overtuigen om een Jatrophaproject op te starten in de Marokkaanse zusterstad van Hasselt

Maar ik onderhoud goede contacten met de overheid en probeer zoveel mogelijk Gambianen van het voordeel van de Jatrophaplanten te overtuigen. Wel blijft het opletten dat niet teveel goede landbouwgrond verloren gaat voor de olieplanten'', meent Vanderbeuken. Een introductie van de Afrikaanse planten in ons land dicht de Nieuwerkerkenaar weinig kansen toe. ,,De plant verdraagt absoluut geen koude temperaturen. En kweken in een serre is ook al geen optie omdat de stookkosten hoger zouden zijn dan de opbrengst'', zegt hij. Vanderbeuken heeft alvast wel Toon Hermans, de Hasseltse schepen voor Ontwikkelingssamenwerking (Groen!), kunnen overtuigen om een Jatrophaproject op te starten in de Marokkaanse zusterstad van Hasselt|2007-04-08 09:49:20 | Reageer |
