The characteristics of water regimes in the seasonably arid tropics are discussed and the contrast in drought environments between cool-dry areas and warm-hot-dry areas is emphasized. In order to improve crop productivity in drought-prone areas it is suggested that more detailed agroclimatological analyses are required and further understanding of the factors controlling crop phenology is needed. Closer matching of crop phenology to climatic events appears to offer the best scope for improving and stabilizing crop yields. However, the importance of adopting a systems approach in crop adaptation to drought is emphasized. Where water is the major limiting factor for the entire production system of a region, improving the drought resistance of a particular crop should not be considered in isolation.
