At present, production of Jatropha oil is expensive, thus making biodiesel more costly compared to fossil diesel.

Major sources of costs To reduce costs, innovative Jatropha plantation management methods are required.

COST CENTRE SOURCES OF COSTS

Weeding Chemicals, poor yields, loss of crop, labour

Pollination Poor yields

Pests/disease management Chemicals, loss of crop, poor yields, labour

Fertilization Fertilisers, poor yields, labour

Tephrosia Vogelii

Tephrosia can be used with garden vegetables, fruits and field crops, to control termites, ants, beetles, aphids, red spider mites, cutworms, various bugs and weevils, stalk borers, flies, etc.

Fertilizer Supply

1.0 tonne of dry seed of Jatropha per ha removes 14.3–34.3 kg of N, 0.7–7.0 kg of P, and 14.3–31.6 kg of K

This makes Jatropha products significantly competitive 22

OBSERVATIONS

23

24

We can see that in trying to address Jatropha management issues to make its products competitive, we consequently end up with outputs such as: • Bioethanol / biodiesel;

• Food (Mealie meal, meat, milk, cooking oil, honey, etc);

• More money earned from Jatropha management products

than from Jatropha products themselves;

• Money made way before starting to reap from Jatropha.

Other than adding Jatropha to the familiar food crops, and processing of biofuels, the trade of keeping goats, chickens and bees is well known.

CONCLUSIONS

25

The above win-win example shows that biofuels and agricultural industries can be developed to be supportive of each other.

For biofuels to expand, Governments need to put in place conducive policies and strategies that promote local uptakes / participation in biofuels industry.

Drought resistant feedstocks/varieties should be promoted/developed to minimize water demand and widen the scope of participation in the biofuels industry.

The global biofuels market is enormous, and projected demand will not be met for a long time to come.

The Biofuels Journey has Begun!!
