implementing a sustainable “ food and fuel ” system in jatropha plantation management
DESCRIPTION
Presented as part of the seminar: South at the Steering Wheel - Improving sustainability in land investment for bioenergy in sub-Saharan Africa 29th May 2012, 08:00 - 17:30 Naturvårdsverket (Swedish EPA), Stockholm, Sweden Speaker: Professor Thomson Sinkala, Thomro farms (Zambia) and Univ. of Zambia In his development of Jatropha based bioenergy, Professor Thomson Sinkala mentions the following issues as best solved in a system, where the different parts contribute to a commercial and sustainable whole in an integrated fashion rather than posing as individual risks for the investor: Pest and Weed management Pollination Improvement Plant Fertilizer Field fencing Livestock and poultry feed (for the dry season) In a similar way to Per Strömberg, at the same seminar, Thomson Sinkala argues that managing each challenge in a creative and adaptive way could mean profit both environmentally as well as commercially.TRANSCRIPT

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
Harvesting Labour, loss of seeds

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.
