IMPACTS OF Prosopis spp. ON ENVIRONMENT AND LIVELIHOODS IN EAST AFRICA: EVIDENCE FROM ETHIOPIA AND KENYA

Abstract: Most invasive alien species reengineer the host ecosystem by altering its structure and functioning so that some new ecosystem services are added and, at the same time, some existing ecosystem services are lost. Prosopis, a woody invasive tree, was intentionally introduced in dry lands of east Africa for its environmental and economic benefits. However, some 40 years later, it escaped from plantations and has invaded significant. This study investigates impacts of Prosopis on the r...

DETERMINANTS OF ADOPTION OF SOIL AND WATER CONSERVATION MEASURES AND PARTICIPATION OF FARMERS IN WATERSHED DEVELOPMENT IN WEST HARARGHE ZONE: THE CASE OF HABRO DISTRICT

Abstract: Land degradation is one of the basic problems facing farmers in the Ethiopian highlands and this limits their ability to increase agricultural production and reduce poverty and food insecurity. Even though various soil and water conservation programs and a number of soil and water conservation were introduced to combat land degradation through the ministry of agriculture, on-and-off farm use of these practices remains below expectations in many degraded areas of the highlands of Et...
