Integrating Soil and Crop Models for Agroclimatological Analysis

In spite of the rapid advances made In the past 2 decades. world food production will barely manage to keep up with population and demand from now until the year 2000. The exceptionally stable climatic period witnessed by the world over the past 40 years is highly unlikely to continue (Cusack. 1983). Climatic Instability will Increase the vulnerability of the already marginal areas currently under cultivation In the semiarid regions of Asia and Africa. Integration of information from soils. crops. and the environment is crucial to evolve carefully managed systems of cultivation that make the most emcient use of natural resources
