Runoff water harvesting from external catchment
This measure consists of non-graded, hand dug ditches that collect and retain runoff water from roads and/or built-up areas outside the target catchment in which agriculture is performed. These ditches hence provide an extra source of water that could be used for irrigation, on top of the water that is available in the catchment itself. Water is lead from the road to the ditch through a hand dug diversion channel. Besides serving as a source of irrigation water, this measure increases soil moisture and recharges the ground water level. The ditches are accompanied by a soil bund to reduce erosion.
