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.
