文摘

In this paper we first analyzed land use/land cover dynamics by the use of ArcGIS for over four decades (1973–2015) in the study area. Based on the results of LULC dynamics as an input, we estimated ecosystem service values (ESV) for different land cover types with the use of global ecosystem service value data sets established. We generally found that forest land decreased and other land uses increased at the expense of forest land. Ecosystem service value also decreased in response to forest land use change. As a result the overall ecosystem services of the study area progressively decreased over the study period indicating the loss of important ecosystem services such as erosion control, genetic resources and water supply. This calls for an appropriate policy formulation such as payment for ecosystem services to conserve the existing resource and restore landscapes with forests. We believe that such studies are very vital in countries like Ethiopia where ground data collection is expensive and difficult to obtain data for previous years.
