Analysis of Land Use Land Cover Change Dynamics by Using GIS and Remote Sensing Techniques: A Case Study of Sensawuha-Gumara Water Shade, Ethiopia

Semegn Gelaye Berie

Rapid increases in population, continuing search for a farm land has induced pressure on natural resource. Sensawuha- Gumara watershed is known for its wealth of resources that offer multiple uses and services. The aim of this research is to analysis land use land cover change in the area that contributes for improved natural resource management and conservation programs. With the help of Geographical Information System and Remote Sensing land use land cover change was estimated for three study periods from Landsat satellite image of each year. It was considered that land use and land cover dynamics of Sensawuha-Gumara watershed for the past 31 years revealed that in 1988 more than 21% of the land was covered by cultivation land, forest coverage of the watershed ranges from 14% to 7% in 1988 and 2019 respectively. In 2019 classification year Sensawuha-Gumara watershed covers 46.27%, 22.18%, 7.33%, 14.02% and 10.20% of agriculture, bare land, shrub land grassland and forest land respectively. In order to make there is no responsible organization that is in charge of forest management in the area of densely populated. In order to improve land use management, the relevant natural resource management and planning of an area is essential.
