Land Degradation In India

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. Districts in the study were selected by land degradation intensity, forming an index of the severity of land degradation in the area, with a focus on gullied lands, soil salinity/alkalinity and open and dense scrubs as indicators. Though the study areas are in India, researchers, policy makers and students around the world will be able to learn from these inputs regarding land degradation to address various challenges associated with sustainable land management and agricultural productivity.

In the Indian context; contributed papers presented at the 22nd Conference of the Institute of Indian Geographers, and International Geographical Union Commission Meeting on Land Degradation and Desertification, held at the Dept. of Geography, Visva-Bharati University, on January 9-11, 2001.

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. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.

This volume provides a comprehensive analysis of the macro- and micro-level issues associated with agrarian distress. It analyses structural, institutional, and policy changes, highlighting the failure of public support system in agriculture. The crisis manifests itself in the form of deceleration in growth and distress of farmers. The case studies from Maharashtra, Andhra Pradesh, Karnataka, Kerala, and Punjab bring out the diversity of conditions prevalent in the states.

This book offers an overview of recent literature on land degradation and its interrelationship with socio-economic development processes in the developing world. It provides an in-depth analysis of land degradation as a physical process, with an emphasis on the local and regional scales. The volume contains a detailed case-study of ravine formation processes in the Chambal valley, a unique but least studied part of the world. Using multi-scale and multi-disciplinary approaches, and combining spatial socio-economic data with remote sensing data, this book provides an in-depth analysis of the causes and implications of land degradation.
