Green gold ... for local development in the Sahel areas of Senegal

Jatropha, a shrub with red flowers and dark green foliage, grows in semi-arid zones (some Sahel countries, Egypt, Madagascar, Central and South America, India, Cambodia, Laos, etc.). Its berries and sap are toxic: jatropha is inedible for humans or animals. Until recently, almost no one therefore cared much about it. But in the last 20 years, agronomists have identified a highly desirable property: when heated, its oil closely resembles diesel! Some already call it green gold ... even though its potential capacities remain mediocre: you need 8 kilos of fruit to produce 1.5 liter of biodiesel.

Nevertheless, the shrubs are robust and produce fruits for 50 years. This crop is therefore worth developing, provided that its contribution can be evaluated accurately - in terms of gain in productivity and income for the peasants who decide to cultivate it.
In Senegal, in the Louga, Kaffrine and Tambacounda regions, this is the plan of Société d'Approvisionnement, de Production, de Commercialisation et de Conseil Agricole des Ententes des Groupements Associés du Sénégal (SAPCA-EGAS), a farm and services coop.

Jatropha also has another property of tremendous value in the parts of Senegal affected by global warming: its roots prevent soil erosion and retain water. But there is no question here of encouraging the farmers to cultivate jatropha without being sure of its profitability and its benefits for the local population.
SAPCA-EGAS therefore decided to limit this cultivation initially to a pilot project, on 200 hectares. 200 families will be concerned. They will be closely monitored by the cooperative's technicians. For three years, they will in fact have to learn to control the whole plant production chain, to extract the oil from the seeds, and to test its use. Jatropha oil should in fact be able to fuel the motors of mills, boreholes, power generators, etc. And SAPCA-EGAS also intends to check that this crop will earn additional income for the family farms in the project, while letting them continue to grow market garden crops.

The Veolia Environnement Foundation is committed to accompany this project for two years, to support the rural development of the regions concerned and the self-sufficiency of the pioneering farmers.
