Abstract: "A "forest-hydrology-poverty nexus" hypothesis asserts that deforestation in poor upland areas simultaneously threatens biodiversity and increases the incidence of flooding, sedimentation, and other damaging hydrological processes. Nelson and Chomitz use rough heuristics to assess the applicability of this hypothesis to Central America. They do so by using a simple rule of thumb to identify watersheds at greater risk of hydrologically significant land use change: these are watersheds where there is a relatively large interface between agriculture and forest, and where this interface is on a steep slope. The authors compare the location of these watersheds with spatial maps of poverty and forests (for Guatemala and Honduras) and with maps of population and forests (for Central America at large). The analysis is performed for watersheds defined at different scales. The authors find plausible evidence for a forest-biodiversity-poverty connection in Guatemala, and to a lesser extent in Honduras. In the rest of Central America, there are relatively few areas where forest meets agriculture on steep slopes--either the forest or the slopes are lacking. And the ratio of these forest/agriculture/hillside interfaces to watershed area declines markedly as larger-scale watersheds are considered. This directs attention to relatively small watersheds for further investigation of the "nexus." This paper--a product of the Infrastructure and Environment Team, Development Research Group--is part of a larger effort in the group to understand the economics of conservation"--World Bank web site.

Forests are intrinsically linked to water – forested watersheds provide 75 percent of our accessible freshwater resources (Millennium Ecosystem Assessment, 2005) – and both forest and water resources are relevant to the achievement of all 17 Sustainable Development Goals. Despite the important interlinkages, the forest-water nexus is often unaccounted for in policy and planning. For example, three quarters of forests are not managed for soil and water conservation, which poses a fundamental challenge to achieving sustainable and resilient communities and ecosystems. It is paramount to employ an integrated approach to forest and water resources in management and policy that takes into account the complexity and contextual nature of forest-water relationships. To achieve this, we must improve our understanding of forest-water relationships within local contexts and at different scales, as well as our ability to design, implement, and learn from landscape approaches that both rely on these forest-water relationships, and impact them. In this context, FAO’s Forest and Water Programme has developed a module-based capacity development facilitation guide for project and community stakeholders involved in forest, water and natural resource management to ensure we apply our knowledge to better manage forests and trees for their multiple benefits, including water quantity, quality and the associated socio-economic benefits that people within and outside forests so heavily depend on.

Reduction of poverty is a tremendous and persistent challenge for the global community. Given that the livelihood of millions is at stake, there is an urgent need to reconsider the causes of and the remedies for poverty. Poverty and its reduction are closely linked to the natural-resources base. The quality and bounty of the local environment certainly affect living conditions of the poor and their poverty is often seen as a contributing factor to the degraded condition of the local environment. Teasing apart the direction of causality in this resource–poverty nexus is a serious empirical challenge. This book contributes to an improved understanding of the economic dimensions of environmental and natural-resource management and poverty alleviation. The ten chapters of the book offer an overview of the current knowledge concerning the relation between poverty, environment and natural-resource use. Three sides of the debate receive particular attention. First, the relation between resource use and poverty is discussed from a theoretical point of view. Second, it is questioned whether payments for environmental services or considering values of resources can be an effective tool for stimulating both sustainable resource use and poverty alleviation. Third, alternative strategies to break the land degradation–poverty cycle are discussed.

This book studies land use change in tropical landscapes, with particular emphasis on the economic processes that influence rates of land degradation and forest clearing. Multidisciplinary contributions draw lessons from data collected between 1992 and 2004 in the Manupali watershed in southern Philippines. Through this detailed case study, the book documents forces leading to land use changes, in particular the potential impacts of institutional evolution and policy reforms, and highlights interrelationships among biological, economic, and social phenomena. This book will be of interest to those studying natural resource economics, soil and water conservation, land use, and agricultural development. The book has 12 chapters and a subject index.

In 2005, The Millennium Ecosystem Assessment (MA) provided the first global assessment of the world's ecosystems and ecosystem services. It concluded that recent trends in ecosystem change threatened human wellbeing due to declining ecosystem services. This bleak prophecy has galvanized conservation organizations, ecologists, and economists to work toward rigorous valuations of ecosystem services at a spatial scale and with a resolution that can inform public policy. The editors have assembled the world's leading scientists in the fields of conservation, policy analysis, and resource economics to provide the most intensive and best technical analyses of ecosystem services to date. A key idea that guides the science is that the modelling and valuation approaches being developed should use data that are readily available around the world. In addition, the book documents a toolbox of ecosystem service mapping, modeling, and valuation models that both The Nature Conservancy and the World Wide Fund for Nature (WWF) are beginning to apply around the world as they transform conservation from a biodiversity only to a people and ecosystem services agenda. The book addresses land, freshwater, and marine systems at a variety of spatial scales and includes discussion of how to treat both climate change and cultural values when examining tradeoffs among ecosystem services.

The World Bank's research is intended to address critical issues and problems facing member governments in developing and transition economies. How can the governments of the poorest countries generate enough revenue to provide the education and health services essential to reducing poverty and promoting growth and development? How can poor countries attract investors to build the infrastructure their economies need? How can they develop systems to bring clean water to the 2 billion people without it today? How can they train teachers and bring to class the 115 million children who have not yet received any education? And how can rich countries be persuaded to lower market barriers, helping to reverse the decline in export prices for poor countries that has left them earning less from trade today than in the 1970s? These are the types of questions that are addressed in this edition of 'The World Bank Research Program: Abstracts from Current Studies'. This volume reports on research projects initiated, under way, or completed from July 2003 through June 2004. It covers 151 research projects on several broad development related issues, including agriculture, health, education, environment, infrastructure, investment climate, and more. The abstract for each project describes the questions addressed, the analytic methods used, the findings to date, and policy implications.

Water is newsworthy: there is, or will be, a world water crisis. Aggravated by climate change, we are approaching the limits of human exploitation of freshwater resources, notably in growing essential food. The complexities and uncertainties associated with improving our management of fresh water take the potential remedies out of the hands of simple, local, hard engineering and into much larger units – the basin, the ecosystem and the global context, and also require longer term perspectives. The Third Edition follows the same structure as its predecessors, presenting the historical and scientific backgrounds to land-water interactions and establishing the links with development processes and policies. Throughout, its two major messages are that our new philosophy should be one of ‘humans in the ecosystem’ and that the guidance from science, being uncertain and contested, must be operationalized in a participatory system of governance based on participation. Following a review of progress towards these elements in the developed world, the international case studies update the situation in the developing world following the Millennium Development Goals, our new emphasis on poverty and on global food supplies. This book covers the multitude of scientific research findings, development of ‘tools’ and spatial/temporal scale challenges which have emerged in the last decade. Tensions are highlighted in the current and future role of large dams, country studies are retained (and considerably updated) and development contexts are explored in greater depth as a dividing line in capacity to cope with land and water stress. "Technical issues" have been expanded to cover major droughts, environmental flows and the restoration of rivers and wetlands. A separate chapter picks up these themes under terms of their relationship with uncertainty and the widespread perception that a new ethos of adaptive management is needed in the water sector. For students of geography, environmental science, hydrology, and development studies this innovative edition provides a reasoned, academic basis of evidence for sustainable, adaptive management of rivers and related large-scale ecosystems using more than 600 new sources. It will also prove invaluable for lecturers and practitioners.
