The degradation rate of Mediterranean steppes, especially in North Africa is 1% per year, and this considered a high rate of degradation. This study conducted in 2014 in the south slope of Al-Jabal Al-Akhdar, northeast Libya to quantify the vegetation recovery rate and assess selected Vegetation Indices (VIs) for mapping rangelands degradation status using remote […]
Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices […]
Trend of vegetation in typology scale has remained uncertain especially in arid ecosystems. Therefore, we aimed to asses two vegetation indices including as the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). Trends and their rates of indices in vegetation types were analyzed by the Mann–Kendall test and Theil–Sen trend estimator. To this […]
