Abstract
Mining and quarrying are extractive enterprises and involve the complete destruction of the habitat of an area where they take place. However, rehabilitation offers a method of restoring habitat and ecosystem function to areas degraded by extractive industries. This paper therefore examines quarry rehabilitation planning practice in purposefully selected quarry site in Addis Ababa in a locality named ‘worku-Sefer’, Akaki Kality sub city. The study employed systematic random sampling method to select households and woody species for this paper. Furthermore, primary and secondary data were collected by the use of interview, site reconnaissance survey and questionnaires. Satellite images were utilized to quantitatively measure and observe the trends & patterns of land use and land cover of the study area. The findings of the paper have been presented in maps, tables, graphs and figures. Percentages were used to show the situation in the site. The findings of the paper revealed that the current quarry rehabilitation practice is very low, i.e., 2.4%. The miss management during quarry operation have created problems related to landscape degradation, changed the pattern of natural water flow and pollution of soil, water, air etc. The overburden materials that need to be kept protected at the site have all been taken away making the rehabilitation efforts very cumbersome and not cost efficient. In addition to these the site is endowed with indigenous and exotic woody species. However, the diversity and abundance of the woody species is affected by the quarry activity since they are found in few areas of the study site. Therefore, the recommendations forwarded in this thesis are assumed to change the situation in practice and made the site more sustainable for the coming generation.
