The Symposium 6-9 February 1987 in New Delhi, India, brought together climatologists and agronomists, experts in irrigation and water-use efficiency, agricultural economists, and development planners from 21 countries to discuss how climatological information can be used to help reduce fluctuations in agricultural output. They presented the results of their research and discussed how to apply scientific understanding to the practical problems faced by farmers. The overriding concern was: how can scientists help farmers exploit favorable agroclimatic patterns and adapt to or protect against unfavorable climatic trends?
