The State of the World's Land and Water Resources for Food and Agriculture is FAO's first flagship publication on the global status of land and water resources. It is an 'advocacy' report, to be published every three to five years, and targeted at senior level decision makers in agriculture as well as in other sectors. SOLAW is aimed at sensitizing its target audience on the status of land resources at global and regional levels and FAO's viewpoint on appropriate recommendations for policy formulation. SOLAW focuses on these key dimensions of analysis: (i) quantity, quality of land and water resources, (ii) the rate of use and sustainable management of these resources in the context of relevant socio-economic driving factors and concerns, including food security and poverty, and climate change. This is the first time that a global, baseline status report on land and water resources has been made. It is based on several global spatial databases (e.g. land suitability for agriculture, land use and management, land and water degradation and depletion) for which FAO is the world-recognized data source. Topical and emerging issues on land and water are dealt with in an integrated rather than sectoral manner. The implications of the status and trends are used to advocate remedial interventions which are tailored to major farming systems within different geographic regions.

Human-induced salinisation is a major threat to the world's land and water resources. Inadequate development of irrigation projects, inefficient irrigation, lack of proper drainage, and environmental mismanagement such as the clearing of native vegetation, are responsible for the loss of millions of hectares of agricultural and grazing land, as well as the misuse of scarce water resources. The first part of this book analyses the problem in the context of the world's population, its climate and its land and water resources. It reviews irrigation methods and crop water requirements, the processes of salinisation, and its management. The second part describes irrigated land, dryland and water-resource salinity problems in 11 countries, which contain approximately 70 per cent of the world's irrigated land. In each case study, background data, environmental conditions and past management practices are given to provide an understanding of why salinity occurs in particular places, and of the management methods employed against it.

This book focuses on the application of geospatial technologies to study the land use land cover (LULC) dynamics, agricultural water management, water resources assessment and modeling, and studies on natural disasters. LULC dynamics is one of the major research themes for studying global environmental change using remote sensing data. The section on LULC dynamics covers the multi-variate criteria for land use and land cover classification and change assessment in the mountainous regions. Further, LULC change detection of the Tons river basin and LULC dynamics at decadal frequency are studied to derive adaptation and mitigation strategies. Landscape-level forest disturbance modeling, together with conservation implications, is also included. The watershed management approach is necessary for comprehensive management of land and water resources of any region, where studies on multi-criteria analysis for rainwater harvesting planning and its impact on land use land cover transformations in rain-fed areas using geospatial technologies are presented in this book. The book will be useful for academics, water practitioners, scientists, water managers, environmentalists, and administrators, NGOs, researchers, and students who are actively involved in the application of geospatial technologies in LULC studies, agricultural water management and hydrological modelling and natural disasters for addressing the challenges being posed by climate change while addressing issues of food and water securities

Africa is endowed with rich land and water resources, which significantly contribute to the development of many economies on the continent. However, land degradation and water pollution remain major challenges facing many African countries. Harnessing Land and Water Resources for Improved Food Security and Ecosystem Services in Africa examines challenges facing land and water resources management in Africa and explores possible measures to improve food security and reduce poverty on the continent. The book is a compilation of research papers, written by eminent researchers and scientists from renowned Universities and reputable organisations in Ghana, Ethiopia, USA, South Africa, Nigeria, the Netherlands and Indonesia. Its main objective is to draw attention to the impact of human activities on land and water resources and the need for the sustainable management of Africa's ecosystem services to improve livelihoods. The individual chapters present relevant case studies on the effects of water and land management practices including urban waste water uses, land grabbing and climate change issues, so as to draw lessons from best practices that can be adopted to mitigate their efforts on food security and the well-being of the African population. The monograph concludes with recommendations on the appropriate strategies for managing wastelands to meet Africa's green energy needs.

'Blue Revolution upturns some environmental applecarts - not for the hell of it, but so we can manage our environment better.' Fred Pearce, New Scientist This updated and revised edition of The Blue Revolution provides further evidence of the need to integrate land management decision-making into the process of integrated water resources management. It presents the key issues involved in finding the balance between the competing demands for land and water: for food and other forms of economic production, for sustaining livelihoods, and for conservation, amenity, recreation and the requirements of the environment. It also advocates the means and methodologies for addressing them. A new chapter, 'Policies, Power and Perversity,' describes the perverse outcomes that can result from present, often myth-based, land and water policies which do not consider these land and water interactions. New research and case studies involving ILWRM concepts are presented for the Panama Canal catchments and in relation to afforestation proposals for the UK Midlands.

This book presents an analysis of land and water resources in Siberia, initially characterizing the landscapes, their ecosystems, crucial processes, human impacts on soil and water quality, and the status quo of available research. Further chapters deal with modern monitoring and management methods that can lead to a significant knowledge shift and initiate sustainable soil and water resources use. These include soil hydrological laboratory measurement methods; process-based field evaluation methods for land and water quality; remote sensing and GIS technology-based landscape monitoring methods; process and ecosystem modeling approaches; methods of resource and process evaluation and functional soil mapping; and tools for controlling agricultural land use systems. More than 15 of these concrete monitoring and management tools can immediately be incorporated into research and practice. Maintaining the functions of great landscapes for future generations will be the reward for these efforts.

The degradation of land and water resources as a result of agricultural activity has had an enormous impact on human societies and economies. It is predicted that, by 2025, most developing countries will face physical or economic water scarcity, compounded by land degradation. In order to alleviate this problem, an advanced understanding of the state of our water resources and the relationships between land use, water management and social systems is needed. Conserving Land, Protecting Water includes an overview of global patterns of land and water degradation and discusses new insights drawn from successful case studies on reversing soil and water degradation and their impact on food and environmental security.

“An important story not just about [Texas’s] water history, but also about its social, economic, and political identity” (Western Historical Quarterly). As a changing climate threatens the whole country with deeper droughts and more furious floods that put ever more people and property at risk, Texas has become a bellwether state for water debates. Will there be enough water for everyone? Is there the will to take the steps necessary to defend ourselves against the sea? Is it in the nature of Americans to adapt to nature in flux? The most comprehensive—and comprehensible—book on contemporary water issues, A Thirsty Land delves deep into the challenges faced not just by Texas but also by the nation, as we struggle to find a way to balance the changing forces of nature with our own ever-expanding needs. Part history, part science, part adventure story, and part travelogue, this book puts a human face on the struggle to master that most precious and capricious of resources, water. Seamus McGraw goes to the taproots, talking to farmers, ranchers, businesspeople, and citizen activists, as well as to politicians and government employees. Their stories provide chilling evidence that Texas—and indeed the nation—is not ready for the next devastating drought, the next catastrophic flood. Ultimately, however, A Thirsty Land delivers hope. This deep dive into one of the most vexing challenges facing Texas and the nation offers glimpses of the way forward in the untapped opportunities that water also presents. “A hard look at a hard problem: finding sufficient water to live in a place without much of it. . . . McGraw’s fine book serves as a useful guide. Observers of Western waterways will want to have this on their shelves alongside the likes of Marc Reisner and Charles Bowden.” —Kirkus Reviews “In stark prose that often gleams like a bone pile bleached in the sun, McGraw travels back and forth across Texas to give a free-ranging but deadeye view of the crisis on the horizon.” —Texas Monthly “It’s hard to write about the slow creep of environmental crises like drought without resorting to shock tactics or getting lost in the weeds . . . [McGraw] draws out the conflicts in compelling ways by drilling into the plight of individual water users. Even if you feel no connection to Texas, these stories are relevant to every part of the country.” —Outside “Interviewing both scientific experts and everyday water users, [McGraw] clearly delineates the competing interests, describes political and geological reality, and makes a compelling argument for statewide water policy that utilizes modern technology and fairly weighs parochial needs against the good of the whole.” —Arizona Daily Star, Southwest Books of the Year
