Abstract

Assessing and monitoring forest cover change researches are useful in providing information necessary to ‎support policies and decisions to conserve, protect ‎and manage the forest on a sustainable basis. This research ‎deals with ‎assessing the past and a recent change in EL-Rawashda Forest using multi-temporal Landsat ‎images for the years 1988, 1998, 2007 and ‎‎2018 and field verification data. In addition to that linear ‎Regression Trend (Slope) analysis that simulates the spatial trends of vegetation cover has been calculated ‎from NDVI results to reflect the changes. The ‎results showed that there was a significant change in EL-‎Rawashda Forest cover over the past 30 years. ‎Moreover, the study found that the increment of ‎agricultural activities inside EL-Rawashda Forest through the toungya agroforestry system was one of the ‎main causes of forest trees clearance. Furthermore, the results of the Slope analysis revealed that change ‎in the forest cover was accounted ‎for 56% of the total area, with almost 3.11% rate of deterioration. ‎These results emphasized that the forest cover change has impacts ‎ on the climate change and forest ‎ecosystem. Therefore, the study results were useful in providing necessary inputs to refine ‎policies and ‎decisions for management and improvement of forests in the area.‎
