Land Degradation

This volume is dedicated to land degradation which is caused by multiple forces-extreme weather conditions and anthropogenic activities that pollute or degrade the quality of soils and land utility-negatively affects food production, livelihoods, and the provision of other ecosystem goods and services. Land degradation can also lead to climate change and affect human health.

This edited book covers all aspects of forest deforestation and degradation in detail and their link to land degradation. Poor natural resource management is often a contributory factor in the depletion of resources particularly like degradation of land which hinders the goals to achieve land degradation neutrality (LDN). Sustainable Development Goal (SDG) target 15.3 states: “By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought, and floods, and strive to achieve a land degradation-neutral world.” To achieve the set goals a comprehensive multidirectional approach is required involving policymakers, field functionaries, researchers, and above all educators. The book compiles the field experiences and wisdom of some of the best researchers and authors working in the field of land degradations for quite a long time.

This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm.

This book discusses land degradation in India using statistical tools such as Principal Component Analysis (PCA) and Regression Analysis (RA), and uses statistical analyses and graphical representations of the causal relationship between land degradation and land productivity to determine linkages with deforestation, climate change and agricultural productivity. While most studies of land degradation in India focus on economic outcomes and physical processes at macro and micro levels, this study addresses land degradation at the meso-level to fill in this gap and provide up-to-date information on often overlooked factors associated with land degradation issues using the latest available data.

Land deterioration, drought, desertification, and water resources shrinkage threaten natural resources, negatively impacting environmental, economic, and political stability. The increasing occurrence of climate change (extremes) impacts land degradation processes, soil erosion by water and wind, and salinization. The researchers have invested several years of scientific research in natural resources deterioration, including soil degradation and erosion, land degradation, desertification, and climate changes, which are interesting enough. However, the link between science and policymaking appears to be less active as serious actions do not take fast. The eighteen chapters of this book focus more on topics related to natural resources deterioration, such as land degradation, desertification, drought, climate change, and analysis of numerous case studies.
