Book Description
This review presents summary information on 45 river and great lake basins of the world, which support inland fisheries. The information presented is drawn from published information in peer-reviewed journals as well as grey literature. Each basin summary is presented in a common format, covering the description of the fishery, estimates of catch and numbers of people engaged in the fishery, important biodiversity features and threats to the fishery. An analysis of the replacement costs of inland fish of the basin is also presented. This is expressed in terms of the water, land and greenhouse gas footprint that would arise if the inland fish that are currently produced had to be replaced with other forms of food (such as aquaculture fish, livestock or field crops).

Book Description
Rural people and communities continue to play important social, economic and environmental roles at a time in which societies are rapidly urbanizing, and the identities of local places are increasingly subsumed by flows of people, information and economic activity across global spaces. However, while the organization of rural life has been fundamentally transformed by institutional and social changes that have occurred since the mid-twentieth century, rural people and communities have proved resilient in the face of these transformations. This book examines the causes and consequences of major social and economic changes affecting rural communities and populations during the first decades of the twenty-first century, and explores policies developed to ameliorate problems or enhance opportunities. Primarily focused on the U.S. context, while also providing international comparative discussion, the book is organized into five sections each of which explores both socio-demographic and political economic aspects of rural transformation. It features an accessible and up-to-date blend of theory and empirical analysis, with each chapter's discussion grounded in real-life situations through the use of empirical case-study materials. Rural People and Communities in the 21st Century is intended for advanced undergraduate and graduate courses in rural sociology, community sociology, rural and/or population geography, community development, and population studies.

Book Description
After decades of regulation and investment to reduce point source water pollution, OECD countries still face water quality challenges (e.g. eutrophication) from diffuse agricultural and urban sources of pollution, that is disperse pollution from surface runoff, soil filtration and atmospheric deposition. The relative lack of progress reflects the complexities of controlling multiple pollutants from multiple sources, their high spatial and temporal variability, associated transactions costs, and limited political acceptability of regulatory measures. This report outlines the water quality challenges facing OECD countries today, presents a range of policy instruments and innovative case studies of diffuse pollution control, and concludes with an integrated policy framework to tackle diffuse water pollution. An optimal approach will likely entail a mix of policy interventions reflecting the basic OECD principles of water quality management – pollution prevention, treatment at source, the polluter pays and beneficiary pays principles, equity, and policy coherence.
