62 What is Desertification? Major Impact, Objective of WDCDD 2022, and what causes of a Drought and How Can We Quantify It?

World Day to Combat Desertification and Drought Quiz

What is Desertification? Desertification refers to the deterioration of land in arid, semi-arid, and dry sub-humid environments. It is mostly caused by human activity and climate variables. Desertification is not synonymous with the growth of existing deserts. Dryland ecosystems occupy more than one-third of the world’s land area and are especially vulnerable to overexploitation and … Read more

59 What is Hyperspectral Remote Sensing and its important Applications

Hyperspectral Remote Sensing Image

Introduction: Hyperspectral Remote Sensing Researchers and scientists utilize hyperspectral remote sensing, (also known as imaging spectroscopy), to identify terrestrial vegetation, minerals, and land use/land cover mapping. Remote sensing involves the examination of features observed in several regions of the electromagnetic spectrum (Remote Sensing Using the Thermal Infrared Spectrum Range). Hyperspectral remote sensing will boost remote … Read more
