Desertification and land degradation are complex phenomena, and we need to understand their causes, consequences, and means to mitigate and combat their impact. Therefore, this book aims to explain the concept and characteristics of drylands, desert and desertification, land degradation, wastelands, and the concept of ecosystem services. It also discusses various types of processes of land degradations, their characteristics, physics and indicators along with mapping, monitoring and assessment of methods involved. Concept of Ocean Biological Deserts is discussed along with international and regional efforts towards combating land degradation and desertification.
Key Features:
- Provides all the aspect of desertification and land degradation at one place
- Includes comprehensive methods to monitor different desertification/land degradation processes
- Comprehensive overview of the mapping, monitoring and modelling techniques
- Role of space borne data in identifying, monitoring and combating desertification is evaluated and reported with real case studies
- Explains the concept of ocean biological deserts, their characteristics and mapping
About the Author: Prof Ajai started his career in 1978 at Space Applications Centre of Indian Space Research Organization (ISRO) and served it for 42 years in various capacities including Group Director, Project Director, Program coordinator, Professor and Emeritus Scientist. At ISRO, he has developed and operationalized techniques, based on space data and geospatial technology, for inventory, monitoring and combating desertification and land degradation, as well as for watershed development and sustainable land management. He has led the national team which carried out the first ever land degradation and desertification status mapping of India. Prof Ajai is a Fellow of National Academy of Sciences, and recipient of several prestigious awards, including Bhaskara Award, William Dixon West Award, GEO-LDN Prize, and National Geomatics Award for Excellence.
Dr Rimjhim Bhatnagar joined Space Applications centre, Indian Space Research Organization (ISRO) in 2004, where she has been pioneering work on the various aspects of land degradation and desertification, including regional and national level mapping, monitoring as well as development of models for desertification vulnerability assessment using space data and geospatial technology. She is a recipient of the prestigious Young Scientist award by the Indian Science Congress Association. Being passionate towards sustainable development, her research work focuses on developing cutting edge models and techniques in both terrestrial and marine ecosystems.
