Water harvesting systems for smallholder producers, tips for selection and design

Harvesting rainwater increases the water available for drinking, domestic and agricultural use. In East and West Africa and South-East Asia, water can be harvested on 40-70 per cent of agricultural land, resulting in large increases in crop production in Uganda, Burundi, the United Republic of Tanzania, and India.  

This brief raises awareness about water harvesting systems and describes the design of water harvesting interventions. It aims to inform stakeholders on the assessment of water demand, water available for harvesting, and the selection of suitable water harvesting systems.
