Land use and land cover change detection in adea woreda, east shoa zone at oromia regional state

Abstract

This study examine the land use and land cover dynamics in Adea woreda from 1986 to 2016 by using Geographic Information System and Remote sensing technology to detect and analyze the changes that takes place over those 30 years. To this end, the research generate and analyze spatial distribution and pattern of land use land cover on the study area, analyze land use land cover change occurred in 1986, 1996 and 2016 and produce land use land cover map. In order to achieve these, both quantitative and qualitative approaches were utilized and use both primary and secondary source of data. 16 elders, experts and managers were selected by using non-probability sampling techniques. Landsat image of 1986, 1996 and ETM of 2016 was employed using ERDAS IMAGINE 2010 and Arc GIS through Maximum Likelihood of Supervised Classification to generate land use and land cover maps. For the accuracy of classified Land Use/Land Cover maps, a confusion matrix was used to derive overall accuracy. Post classification method was employed to identify gains and losses between different Land Use Land Cover classes. The satellite image results show that Agriculture land and Built up area shows decreasing and increasing trend within the study period respectively. Therefore, it is recommended that Adea district administration, community and all concerned body should create awareness about family planning, which is major cause of problem.
