Community Based Area Closure in Abagerima Watershed.This photo shows tree, grass, shrubs and bush vegetation. (Bekalu Bitew)
The area closure technology has been applied in community-based watershed development in Abagerima since 2012.
The area was closed from livestock free grazing, allowing grasses, bushes and trees to recover, thereby conserving soil and water, improving soil moisture, and preventing on- and off-site erosion.
Area closures serve as buffer zone by preventing siltation, acting as meteorological regulator, enhancing the water cycle, and improving the productivity of the land.
Generally, area closures can enhance the livelihoods of the community in social. economic, political. environmental and cultural aspects.
The major activity at the beginning is to create community awareness about the technology. After that, construction of trenches, planting of trees (e.g. grevillea rubusta) and some maintenance is needed.
Area closures have many benefits, like economical, reducing conflicts, etc., and most land users know these benefits and thus accept the technology.
