2. 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

Limburger maakt biodiesel

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.

BIO-DIESEL IN THE GAMBIA

Pierre, a dedicated man commited to reducing poverty in the Gambia has embarked on a new project with fellow colleagues to help people make a living. The belgium organisation recently launched a website to present their new efforts for The Gambia. They Buy Jatropha curcas (Tabanani in Wolof, Baganaa in Mandinka, Kiidi in Fula)is a widespread plant in Gambia as in most tropical countries; it is often used as a live fence, and its leaves are used to treat certain skin ailments. The hedgerows protect agricultural soils against erosion, and it is inedible to animals. The oil from the seeds can be used to make soap, and also as fuel for diesel engines. Jatropha is a tree, growing in the Gambia bush. The seeds contain oil that can be used as fuel: about 1/3 of the weight of the seeds is oil ! Jatropha is a tree, growing in the Gambia bush.
