Abstract

This is one of 280 summaries describing key outputs from the projects run by DFID's 10-year Renewable Natural Resources Research Strategy (RNRRS) programmes.

Summary for Project title: R7888: Promotion of rainwater harvesting systems in Tanzania - Phase 1.

New approaches to rainwater harvesting (RWH) are improving life in Tanzania's semi-arid areas. Previously, lack of awareness by planners and farmers meant RWH was not used much. A holistic system integrates interventions ranging from in situ RWH (soil and water conservation), to supplementary irrigation using water harvested from macro-catchments. The basic principle is to start by preventing runoff and promoting infiltration of the rain falling directly on the field. Another approach combines RWH with road and railway drainage infrastructure to contain flash floods while at the same time increasing water availability for agriculture and livestock. In Tanzania, use is widespread in the districts originally targeted by the project and spreading. In Rwanda, projects have been launched in several areas.
