3 Jatropha: Experience of Agro-Forestry & Wasteland Development Foundation, Nashik, India Started by Vinayakrao Patil, a local farmer Commercial plantation for 17 years from 1986 to 2003 – 1986: 8 acres – At its peak in 1995: >20,000 acres (>8,000 ha) – At the close in 2003: Nil (as farmers were frustrated and gradually shifted to other crops) Number of farmers > 2,500 Elite Curcas varieties from world over Visits by persons from: – World Bank Mission on Forestry, Hohenheim University, Swiss Development Corporation, Governments of India and Maharashtra (local state Govt.), several NGOs

4 Jatropha: Learnings of Agro-Forestry & Wasteland Development Foundation, Nashik, India Spacing of 3m X 3m is necessary for block plantation. Shorter spacing (2X2 or 3X2) is definitely unsuitable For single row, hedge plantation, 2mX2m is fine Fertilizer application is necessary: “If there is no input, there will be no output” is universally true Pruning is necessary for optimum yield Sunlight is necessary for higher yield (the old rule) With irrigation, the vegetative growth is high but the yield increase is not proportionate The seed yield stabilizes from the 7 th year onwards

7 The average yield, even after seven years, was <500 kg / acre per year of sun-dried seeds i.e. Less then 1.25 M.T. / ha per year Consequently, after 17 years, it was decided to drop the project The experience of other old projects is not different (e.g. Bharatiya Agro Industries Foundation, started by Mahatma Gandhi) Therefore, it is time now to take a pause, It is time for introspection …

8 Jatropha: Issues When one walks on a jatropha field, every plant looks different: Yield (uniformity) – Branching – Days to first flowering, – Number of flushes in a year – Female to male flower ratio – No. of seeds per fruit – Seed weight Oil content Oil quality Clear need to develop high yielding varieties and Seed multiplication / propagation
9
9 Jatropha: Issues Toxicity The varieties propagated are toxic It is fine to put a few M.T. of toxic cake in the soil as fertilizer But can we put millions of M.T. of toxic waste year after year? What impact will it have on underground water? On the soil? Host to diseases (E.g. Cassava mosaic virus) A jatropha plantation can cause havoc to the neighboring plantations e.g. cassava
10
10 Jatropha: Conclusion and proposed actions Conclusion The current plantations are not sustainable unless high yielding varieties are introduced and their seed multiplication stabilized If we continue with them, we risk creating many sick units We cannot make farmers commit their lands for 50 years to uneconomic varieties It will be a major disservice to jatropha Hence we should consider a temporary ban on further plantation for the time being
11
11 Jatropha: Conclusion and proposed actions Next steps Invite seed industry expertise for varietal improvement and seed multiplication Public-Private partnership may be considered in – Breeding – Marker development – Seeds production / Propagation Global communication necessary IFAD can play a major role in defining research objectives and fund research together with industry

13 Background: Emerging Realities in Agriculture… In short to medium term, crude oil price are likely to stay at around $ 100 / barrel or may even reach higher levels This will directly impact food prices on account of: Rise in demand for land use for biofuels crops and Higher cost of agricultural inputs (fertilizers, labour, pesticides as well as transport of goods to and from farm-gate) Countries having food surplus will divert some of their land for biofuels crops (e.g. U.S.A., Brazil) Population growth and rapid urbanization in the developing world will put further pressure on land available for food production
14
14 Background: Emerging Realities in Agriculture… Land hitherto considered unsuitable for agriculture will have to be brought under cultivation Stress tolerant crops which can survive under severe agro-climatic conditions will have to be developed Land productivity will have to substantially increase from its present level Crops efficient in converting solar energy into stored energy (solid or liquid) will have to developed / adapted New bio-fuel crops, hitherto not cultivated commercially viz. jatropha will unknown will
