One of the objectives of ICRISAT  is to develop farming systems that will help in crease and stabilize agricultural production through better use of natural and human resources in these as on ally dry semi- arid tropics (SAT). Resource management  plans are in complete without consideration of trees. There are lands where mixes of crops, trees, and grasses are ideal. We must optimize their production and maximize returns to the farmer  without detriment to the environment. Unlessa system is attractive to are source-poor farmer, it may not be adopted. In appropriate agricultural and forestry production systems and population growth (animal and human) out stripping production lead to land degradation. The proble miss evere in the tropics, where the pressure of population is high, ecosystems fragile, and exploitation of forest coverruth less. The consequence is that wood supplies are dwindling. An FAO study on "Agriculture Towards 2000" estimates that even if crop yield on lands already cultivated were to increase by 72%, an other 200 million ha. will have to be cleared in the world in the next 15 years for meeting food needs. Most of the prime lands are already cropped. In the Indian SAT,  78- 80 % of the area is under cultivation as against the mean of 40% for the whole country. With the technology now available or in the pipeline, India may be able to meet its food needs. But there may not been ough fuel wood available to cook  it. That rural people rely on trees for fuel, housing, implements, fodder, and a host of other purposes is in disputable. This need is unalterable, and will grow to be come more expensive to India both monetarily and ecologically. Some estimates show that India will consume 200 million cubicmeters of wood for fuel alone in 1985. The Fuel wood Committee of the Government of India estimated in 1982 that atleast 3 million ha will have to be planted each year under quick- yielding fuel wood trees, up to 2000 AD
