A primary goal of many remote sensing projects is to characterize the type, size and condition of vegetation present within a region. By combining data from two or more spectral bands we obtain what is commonly known as a vegetation index (VI), which enhances the vegetation signal, while minimizing solar irradiance and soil background effects. This study addresses the computation of Normalized ...

the degradation rate of mediterranean steppes, especially in north africa is 1% per year, and this considered as high a rate of degradation. this study conducted in 2014 in the south slope of the 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 sensing technology. thro...

Drought was a severe recurring phenomenon in Iraq over the past two decades due to climate change despite fact that has been one of most water-rich countries Middle East past. The Iraqi Kurdistan Region (IKR) is located north Iraq, which also suffered from extreme drought. In this study, drought severity status Sulaimaniyah Province, four provinces IKR, investigated for years 1998 2017. Thus, L...
