Farming without irrigation

Picture copyright ANDERSON et al.

Rainfed agriculture refers to farming that relies solely on rainfall for crop growth, versus irrigated agriculture that use extra water. Rainfed agriculture accounts for 60-95% of farmlands in developed countries in Africa, Asia and Latin America. Agronomists Anderson et al. review recent research on rainfed agriculture and suggest that conservation agriculture should improve soil water content and, in turn, crop yields.
