Sokoto state (Sustainability) Rain water harvesting

The Sokoto basin is part of north-western Nigeria; an area characterised by semi-arid condition largely due to high rainfall variability leading to frequent drought occurrence and water scarcity in the region. Rainwater harvesting can serve as an effective coping strategy in addressing the water deficit experienced by the people during the long dry season. This paper aimed to assess the rainwater harvest potential of Sokoto basin using variable landscape approach to improve water resource management. Simulations were run for 6 sequential rainfall years (2000-2005) to determine the distribution of rainfall input into output of runoff, actual evapotranspiration and groundwater outflow. The runoff and some groundwater outflow are considered as potential components for harvest and storage to be used after rainy season. The high potential areas for harvest were identified and classified using GIS and remote sensing techniques. The paper recommends a unified rational approach to water resources planning and development and suggests that small household water reservoirs and community earth dams should be built to capture excess runoff from rooftops and high runoff contributing landscapes for use during the dry season.
