This work exposes how water flow links nature and society through water's many parallel functions as the "blood stream" of both the natural environment and the embedded human environment - and the resulting conflicts that arise. The authors argue that a sustainable future depends fundamentally on our ability to manage these trade-offs. They advocate an ecological approach to land/water/environmental problems and argue for viewing precipitation as the gross water resource.; Distinguishing between terrestrial aquatic ecosystems, they show how an ecological approach can be expressed in water-related trade-offs, incorporating criteria for long-term resilience. Based on per capita needs for an acceptable nutritional diet, the authors analyse the amounts of water needed for global food production by 2050 and identify potential sources. Drawing on small-scale experiences in Africa and Asia, they also cover the vulnerability of the semi-arid tropics, disentangling it into green and blue water scarcity components.

Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.

State of the World 2006 provides a special focus on China and India and their impact on the world as major consumers of resources and polluters of local and global ecosystems. The report explains the critical need for both countries to "leapfrog" the technologies, policies, and even the cultures that now prevail in many western countries for the sake of global sustainability—and reports on some of the strategies that China and India are starting to implement. Besides the focus on China and India, State of the World 2006 looks at actions corporations can take to be more socially responsible; examines the potential socioeconomic, health, and environmental implications of nanoscale technologies; assesses the impacts of large-scale development of biofuels on agriculture and the environment; describes mercury sources, industrial uses, and health hazards worldwide; and provides an overview of the need to safeguard freshwater ecosystems, with examples of proven approaches in cities, villages, and farming regions around the world.

The rapidly changing nature of animal production systems, especially increasing intensification and globalization, is playing out in complex ways around the world. Over the last century, livestock keeping evolved from a means of harnessing marginal resources to produce items for local consumption to a key component of global food chains. Livestock in a Changing Landscape offers a comprehensive examination of these important and far-reaching trends. The books are an outgrowth of a collaborative effort involving international nongovernmental organizations including the United Nations Food and Agriculture Organization (UN FAO), the International Livestock Research Institute (ILRI), the Swiss College of Agriculture (SHL), the French Agricultural Research Centre for International Development (CIRAD), and the Scientific Committee for Problems of the Environment (SCOPE). Volume 1 examines the forces shaping change in livestock production and management; the resulting impacts on landscapes, land use, and social systems; and potential policy and management responses. Volume 2 explores needs and draws experience from region-specific contexts and detailed case studies. The case studies describe how drivers and consequences of change play out in specific geographical areas, and how public and private responses are shaped and implemented. Together, the volumes present new, sustainable approaches to the challenges created by fundamental shifts in livestock management and production, and represent an essential resource for policy makers, industry managers, and academics involved with this issue.

Transboundary Water Governance in Southern Africa

This collection of Southern African case studies contributes to the burgeoning literature on transboundary water governance, particularly as it applies to areas of the Global South/developing countries. Specifically, the collection interrogates the idea of the 'boundary.' Transboundary management is most commonly conceived of as the management of surface and groundwater shared by two or more sovereign countries. This conceptualization is codified in international law, devised in the first instance as bilateral agreements concerning specific uses of (primarily surface) water, often along specific stretches of river. Through time, these practices have been upscaled to generalized principles expressed as rules, norms, and procedures for the management of all 'international rivers.' While the world's countries seem to be moving steadily toward an accepted framework for transboundary water resources management, it should be noted that the de facto use of much of the world's shared freshwater resources remains outside this mostly ideal-typical framework. Indeed, in contrast to the rationally constructed framework for the management of water in all its forms and across all uses, de facto management â?? at whatever social scale â?? reflects water's changing role and place within the history of uneven global development.

This collection of papers represents the outcomes of the International Symposium held in Delft, The Netherlands, on June 13-15, 2007, at the occasion of the 50th anniversary of the UNESCO-IHE Institute for Water Education. The papers discuss how to contribute to the sustainability of effective international development and water management with a digest of lessons learned on local knowledge and capacity development. Authors expose recent research, strategies and policy positions. Water for a Changing World starts with an introduction and overview of the water resources and the water supply and sanitation sectors in developing countries and worldwide. Topics of these reviews are water security, environmental integrity, the newest earth system science technologies, integrated urban water management, and the global-local nexus of water governance. The second part presents positions on catalyzing and disseminating knowledge and capacity development in response to the current challenges and opportunities. It consists of a variety of papers on theory and analysis of capacity development, methods and case studies, and policy positions. The authors represent a diverse and representative group of prominent actors, practitioners and academics within the water, sanitation and development sectors.
