Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerat

Soil degradation causes a shrinking of arable land resources, and the persistence of starvation and malnutrition. The depletion is compounded by the increasing populations of developing tropical nations, and the conversion of agricultural land to other uses. As a result, per capita grain harvesting and irrigated land is in steady decline all over the world. The decrease in horticultural resources and productivity has inspired Soil Quality and Agricultural Sustainability, which is based primarily on papers presented at the 1996 conference on soil degradation, sponsored by Ohio State University, the USAID and the International Agricultural Research Centers. The book addresses itself to six concerns: basic concepts and global issues, nutrient and water inputs, soil quality management in Asia, in Africa, and in the Tropical Americas, and future priorities. The Editor's goal is a new paradigm in soil quality research: a multidisciplinary approach. He proposes that an erosion management program include soil scientists, hydrologists, climatologists, sedimentologists, geographers, agronomists, agricultural engineers, land use planners, economists, anthropologists and social scientists. Lal advocates an optimistic, forward-thinking brand of soil science that concentrates on conservation and fertility. The 26 chapters explore what Lal considers to be the priorities: agricultural sustainability, soil quality, food security, quality restoration, long-term management, and the failure to adopt new technology. In sum, they paint a comprehensive portrait of the current state, and future prospects, for worldwide agronomic viability.

'Action is needed to fight poverty by sustaining the environment and the use of natural resources. Land Quality, Agricultural Productivity, and Food Security explores a range of factors driving food security. The book offers an assessment to link quality of the available land resources with productivity of land and the ability to ensure food security. It offers a mixture of broad-scale assessments across the globe, with detailed case studies, deepening our understanding of economics and decision-making mechanisms. It is recommended to researchers, as well as actors in the private and public domain, who are keen to improve their understanding of the appropriate actions that ensure food security in the decade to come.' - Floor Brouwer, Agricultural Economics Research Institute (LEI), The Hague, The Netherlands Land quality and land degradation affect agricultural productivity and food security, but quantifying these relationships has been difficult. Data are extremely limited and outcomes are sensitive to the choices that farmers make. The contributors to this book - including soil scientists, geographers, and economists - analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: * the extent to which differences in land quality generate differences in agricultural productivity across countries * how farmers' responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and * whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.

Feeding the increasing global population, which is projected to reach ~10 billion by 2050, there has been increasing demands for more improved/sustainable agricultural management practices that can be followed by farmers to improve productivity without jeopardizing the environment and ecosystem. Indeed, about 95% of our food directly or indirectly comes from soil. It is a precious resource, and sustainable soil management is a critical socio–economic and environmental issue. Maintaining the environmental sustainability while the world is facing resource degradation, increasing climate change and population explosion is the current challenge of every food production sectors. Thus, there is an urgent need to evolve a holistic approach such as conservation agriculture to sustain higher crop productivity in the country without deteriorating soil health. Conservation Agriculture (CA), is a sustainable approach to manage agro–ecosystems in order to improve productivity, increase farm profitabilty and food security and also enhance the resource base and environment. Worldwide, it has been reported various benefits and prospects in adopting CA technologies in different agro-climatic conditions. Yet, CA in arid and semi-arid regions of India and parts of south Asia raises uncertainities due to its extreme climates, large scale residue burning, soil erosion and other constraints such as low water holding capacity, high potential evapotranspiration, etc . Thus, the proposed book has 30 chapters addressing all issues relevant to conservation agriculture/no-till farming system. The book also gives further strengthening existing knowledge in relation to soil physical, chemical and biological processes and health within close proximity of CA as well as machinery requirements. Moreover, the information on carbon (C) sequestration, C credits, greenhouse gas (GHG) emission, mitigation of climate change effects and socio-economic view on CA under diverse ecologies namely rainfed, irrigated and hill eco-region is also deliberated. For large scale adoption of CA practices in South Asian region especially in India and other countries need dissemination of best-bet CA technologies for dominant soil types/cropping systems through participatory mode, strong linkages and institutional mechanism and public-private-policy support. We hope this book gives a comprehensive and clear picture about conservation agriculture/no-till farming and its associated problem, challenges, prospects and benefits. This book shall be highly useful reference material to researchers, scientists, students, farmers and land managers for efficient and sustainable management of natural resources.

Soil-The Basis of All Terrestrial LifeAncient civilizations and cultures-Mayan, Aztec, Mesopotamian, Indus, and Yangtze-were built on good soils, surviving only as long as soils had the capacity to support them. In the twenty-first century, productive soil is still the engine of economic development and essential to human well-being. The quality of

Sustainable management of soils is an important global issue of the 21st century. Feeding roughly 8 billion people with an environmentally sustainable production system is a major challenge, especially considering the fact that 10% of the world’s population at risk of hunger and 25% at risk of malnutrition. Accordingly, the 68th United Nations (UN) general assembly declared 2016 the “International Year of Pulses” to raise awareness and to celebrate the role of pulses in human nutrition and welfare. Likewise, the assembly declared the year 2015 as the “International Year of Soils” to promote awareness of the role of “healthy soils for a healthy life” and the International Union of Soil Science (IUSS) has declared 2015-2024 as the International Decade of Soils. Including legumes in cropping systems is an important toward advancing soil sustainability, food and nutritional security without compromising soil quality or its production potential. Several textbooks and edited volumes are currently available on general soil fertility or on legumes but‚ to date‚ none have been dedicated to the study of “Legumes for Soil Health and Sustainable Management”. This is important aspect, as the soil, the epidermis of the Earth (geoderma)‚ is the major component of the terrestrial biosphere. This book explores the impacts of legumes on soil health and sustainability, structure and functioning of agro-ecosystems, agronomic productivity and food security, BNF, microbial transformation of soil N and P, plant-growth-promoting rhizobacteria, biofertilizers, etc. With the advent of fertilizers, legumes have been sidelined since World War II, which has produced serious consequences for soils and the environment alike. Therefore, legume-based rational cropping/soil management practices must support environmentally and economically sustainable agroecosystems based on (sequential) rotation and intercropping considerations to restore soil health and sustainability. All chapters are amply illustrated with appropriately placed data, tables, figures, and photographs, and supported with extensive and cutting-edge references. The editors have provided a roadmap for the sustainable development of legumes for food and nutritional security and soil sustainability in agricultural systems, offering a unique resource for teachers, researchers, and policymakers, as well as undergraduate and graduate students of soil science, agronomy, ecology, and the environmental sciences.

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.
