Abstract: The 1980s have witnessed substantial increases in food production. \nThis has raised expectations that improved systems of \nfarming will be rapidly adopted by small farmers in developing \ncountries. The agroecological environment of such farms is \nfragile and the farmers are resource-poor. Therefore, strategies \nrecommended for increasing food production must be ecologically \nsound and should result in sustainable agriculture. \nSystem modeling can greatly expedite the search for improved \ndevelopment strategies. Recent advances in crop modeling \nhave made it possible to simulate yields and growth of several \ncrops under varied soil and weather conditions with different \nmanagement practices. This bulletin describes the framework \nof CERES (Crop Estimation Through Resource and Environment \nSynthesis) models developed by the International Benchmark \nSites Network for Agrotechnology Transfer ( IBSNAT) \nand The International Crops Research Institute for the Semi- \nAr i d Tropics ( ICRISAT) . Recent wor k on the simulation of \nnitrogen transformation in soils at the International Fertilizer \nDevelopment Center ( IFDC) is discussed. A section on risk \nanalyzes the cost-benefit implications of various inputs for \nincreased crop production. RESCAP—a resource capture \nmodel developed at ICRISAT Center is presented. \nThis publication is a cogent source book on the current status \nof development of CERES and RESCAP models, their data \nneeds, outputs, and applications.
