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
One of the cornerstones of life's wonders is the vast array of species filling the planet. From plants to animals to humans, there is no shortage of beings to provide 'spice of life' variety is said to be. Periodically, scientists announce the discovery of a 'new' form of life, so it seems as if Earth is capable of producing new species just to keep us on our toes. At times, the immense breadth of living things can even feel overwhelming, as one pauses to ponder how numerically insignificant humans are when compared to the insect population. Given the biological diversity of the planet, it is incumbent upon humans to safeguard the natural beauty of the environment. To that end, conservation takes on special importance, necessitating the balancing of industrial expansion with preserving the flora and fauna surrounding us. This book is an important tool in understanding and researching the many different life forms spanning the globe. Collected here is a substantial and carefully selected listing of relevant literature on biological diversity and its conservation. Following this bibliography are author, title, and subject indexes to allow for further access to this information. The sheer bulk of the works about biological diversity can be so intimidating that a book such as this one becomes useful in sorting through the resources about the importance of life's variety.

Book Description
By affecting evapotranspiration and influencing how water is routed and stored in a basin, forests, wetlands and floodplains play a crucial role in the hydrological cycle. Although they are widely attributed a major role in regulating flows (i.e., both attenuating floods and maintaining flow during dry periods), these services are rarely factored into the planning and management of water resources. One reason for the failure to include them is lack of understanding. Very often the extent to which natural regulating functions really occur is unclear. Against this background, this report describes a simple, pragmatic approach for quantifying the flow regulating functions of natural ecosystems. The method has been applied at 14 locations in the Zambezi River Basin.

Book Description
Tilapia Culture, Second Edition, covers the vital issues of farmed tilapia in the world, including their biology, environmental requirements, semi-intensive culture, intensive culture systems, nutrition and feeding, reproduction, seed production and larval rearing, stress and disease, harvesting, economics, trade, marketing, the role of tilapia culture in rural development and poverty eradication, and technological innovations in, and the environmental impacts of, tilapia culture. In addition, the book highlights and presents the experiences of leading countries in tilapia culture, thus making it ideal for tilapia farmers and researchers who seek the most relevant research and information. The new second edition not only brings the most updated information within each chapter, but also delivers new content on tilapia transfers, introductions and their impacts, the use of probiotics and other additives in tilapia culture, tilapia trade, including marketing, and sustainability approaches and practices, such as management practices, ecosystem approaches to tilapia culture, and value chain analyses of tilapia farming. - Presents the biology of tilapia, including taxonomy, body shapes, geographical distribution, introductions and transfers, gut morphology, and feeding habits - Covers semi-intensive tilapia culture in earthen ponds, tanks, raceways, cages, recirculating systems, and aquaponics - Provides the latest information on brood stock management, production of monosex tilapia, seed production, and larval rearing under different culture systems - Highlights the most common infectious and non-infectious diseases affecting farmed tilapia, with a full description of disease symptoms and treatment measures - Provides an in-depth exploration of tilapia economics, trade and marketing

Book Description
This report is the result of a joint project of the Southern African Development Community (SADC), the World Bank, the International Bank for Reconstruction and Development, Swedish International Development Agency (Sida) and the World Conservation Union (Regional Office for Southern Africa) which investigated the threats to precious water resources in southern Africa, and to the environment that sustains them. The full colour, glossy report was intended as a SADC contribution to the United Nations summit on Sustainable Development in Johannesburg in 2002, and to the New Partnership for Africa's Development. The report provides a framework for the sustainable management of water resources, and presents solutions for long-term protection and appropriate utilisation of water in the counties of the region ? the DRC, Angola, Tanzania, Zambia, Malawi, Zimbabwe, Mozambique, Namibia, Botswana, Swaziland, Lesotho and South Africa. Some key messages that pervade the report are: firstly that the effective and sustainable utilisation and management of water resources are essential prerequisites for sustaining all forms of life and livelihoods, and for fostering overall socio-economic development and poverty reduction in the region; and that moreover, sustainable water resources management must be balanced between the short-term needs of the people and their human development, and the protection of the natural resource base and environment.
