This study examines fingerponds in the Lake Victoria wetlands in Uganda. It discusses the importance of organic manure applications in enhancing nutrient levels, phytoplankton, and periphyton productivities and ultimately fish production. The study demonstrates that organic manures enhance algal development and fish production, emphasizing that close monitoring and control are needed. It explores the enhancement of fish yields using animal manure, fermented green manure, and artificial substrates for periphyton development, covers the good management practices required to regulate pond inputs and conditions, and discusses the role of fingerponds in ameliorating food security for resource-poor communities.

The UN Millennium Summit in 2000 pledged to achieve a set of Millennium Development Goals to be achieved by 2015. They include halving by 2015 the number of undernourished people in the world, which currently stand at 850 million people. This book explores ways and means of achieving the Millennium Development Goal in respect of Food Security. With contributions from world experts.

As with the original, Forest Hydrology: An Introduction to Water and Forests, Second Edition is a uniquely comprehensive volume that introduces water resources while also exploring the forest-water relation. This new edition ads a chapter on forests and flooding, another on forest and stream habitat, sections on snow vaporization processes and GIS methods in hydrology research, and a new appendix on forest interception measurements. Employing examples and case studies, it provides tools and background to help natural resource managers, including those without hydrology and forestry backgrounds, play an active role in land-use planning

With increasing trade between nations and continents, water is more and more often used to produce goods that are exported. Can international trade be a tool to enhance global water use efficiency, or is it a means of shifting the environment burden to a distant location? The water footprint of nations is a consumer-based indicator of water use which reveals the impacts of local consumption on global water resources and the dependency of any country on external water resources.

A unified discussion of groundwater and its economic importance, this book explores cost/benefit analysis and approaches for the different aspects of use, protection, and remediation. It examines the development of the legal basis for use and access rights, then addresses drinking water, irrigation, and efficient waste disposal. The author considers micro- and macro-economic factors, cost benefit tools, sustainability, and policy evaluation, ease of policy implementation, and societal acceptance. He synthesizes key points into practical steps for future application, describing ways to evaluate the economics of ground water use in the context of the larger ecosystem and its sustainability.
