Aeolian Desertification

This book summarizes contemporary research on land degradation, desertification, and how such issues relate to socioeconomic growth in developing countries. With a focus on local and regional levels, the book offers an in-depth analysis of aeolian action as a physical process, causes of land degradation, and desertification. The causes and effects of land degradation were investigated by utilizing multiscale and multidisciplinary methodologies, merging spatial socioeconomic data with remote sensing data, and using multiple levels and disciplinary approaches. The book also describes how to combine GIS with cutting-edge technologies such as remote sensing, geostatistics, scanning electron microscopy (SEM) and energy-dispersive X-ray (EDAX) analysis, and analytical hierarchy approaches, among others. Included is a thorough case study of the unusual but understudied semi-arid Anantapur district in Andhra Pradesh, South India. This book encourages the participation of all socioeconomic groups in decision-making and assists authorities and planners in developing suitable plans for the sustainable agricultural growth of an area. The book is an invaluable resource to comprehend and resolve issues about sustainable environmental planning and management.

Assesses the impact of land degradation and desertification in semi-arid regions Enables the long-term assessment of land cover changes using geospatial approaches Analyzes the effect of sand grain shape involved in the rate of aeolian sand migration
