Book Description
This publication contains background documents and papers presented at a workshop on integrated irrigation aquaculture (IIA), held in Mali in November 2003, as well as the findings of FAO expert missions on IIA in the West Africa region. The rationale for IIA development lies in its potential to increase productivity of scarce freshwater resources and to reduce pressure on natural resources, issues of particular important in the drought-prone countries of West Africa.

Book Description
The African Water Resource Database (AWRD) is a set of data and custom-designed tools, combined in a geographic information system (GIS) analytical framework, aimed at facilitating responsible inland aquatic resource management with a focus on inland fisheries and aquaculture. It thus provides a valuable instrument to promote food security. The AWRD data archive includes an extensive collection of datasets covering the African continent, including: surface waterbodies, watersheds, aquatic species, rivers, political boundaries, population density, soils, satellite imagery and many other physiographic and climatological data. This technical paper is the first of two publications about the AWRD, and it gives a general overview addressed both to administrators and managers, as well as for professionals in technical fields. The second part of this technical paper is available separately (ISBN 9789251056479).

Book Description
Recommendations made include the need: for a background study and consultation on the normative framework for fish trade and food security; for the preparation of technical guidelines on the Code of Conduct for Responsible Fisheries (CCRF), fish trade and food security; and better training to improve capacity of policy makers and technical personnel on international issues dealing with fish trade and food security.

Book Description
The importance of fisheries is not lost in the global policy arena. What is often overlooked in the general discourse, however, is the significant difference between small-and large-scale fisheries. Major rethinking about all aspects of small-scale fisheries is required, including their contribution to catches, employment, livelihood, food security and conservation. This book is a collection of essays about the diverse, complex and dynamic contexts that characterize small-scale fisheries around the world. The essays highlight the strengths, capacity, motivation and contributions associated with this fishing sector. They remind us that solutions and opportunities for the viability and sustainability of small-scale fisheries can be found, once the issues are understood from a holistic perspective and possible options, including inventive governance arrangements, are fully explored. The authors are scientists and practitioners who work in small-scale fisheries in various parts of the world, many of whom participated at the first World Small-Scale Fisheries Congress (WSFC), held in Bangkok in October 2010, and are members of the global research network for the future of small-scale fisheries, Too Big To Ignore. The editor, Ratana Chuenpagdee, the initiator of the WSFC, is Canada Research Chair in Natural Resource Sustainability and Community Development at Memorial University of Newfoundland, Canada.

Book Description
'An interesting book catering perhaps for a more specific audience. It does however provide a somewhat new view of the problems of the field of biological invasions and is worth the effort.' - Ann Sundqvist, M2 Best Books 'Once again, Charles Perrings and colleagues have broken new ground by applying economic and ecological analysis to the very real problem of biological invasions. This is path-breaking work in what promises to be a new sub-discipline within environmental economics.' - David Pearce, University College London, UK Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries. The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.

Book Description
"(Reprint. First published in 1998) The present study is an update of an earlier assessment of warm-water fish farming potential in Africa, by Kapetsky (1994). The objective of this study was to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa. The study was based on previous estimates for Africa by the above author, and on estimates of potential for warm-water and temperate-water fish farming in Latin America by Kapetsky and Nath (1997). However, a number of refinements have been made. The most important refinement was that new data allowed a sevenfold increase in resolution over that used in the previous Africa study, and a twofold increase over that of Latin America (i.e. to 3 arc minutes, equivalent to 5 km x 5 km grids at the equator), making the present results more usable in order to assess fish farming potential at the national level. A geographical information system (GIS) was used to evaluate each grid cell on the basis of several land-quality factors important for fish-farm development and operation regardless of the fish species used. Protected areas, large inland water bodies and major cities were identified as constraint areas, and were excluded from any fish farming development altogether. Small-scale fish farming potential was assessed on the basis of four factors: water requirement from ponds due to evaporation and seepage, soil and terrain suitability for pond construction based on a variety of soil attributes and slopes, availability of livestock wastes and agricultural by-products as feed inputs based on manure and crop potential, and farm-gate sales as a function of population density. For commercial farming, an urban market potential criterion was added based on population size of urban centres and travel time proximity. Both small-scale and commercial models were developed by weighting the above factors using a multi-criteria decision-making procedure. A bioenergetics model was incorporated into the GIS to predict, for the first time, fish yields across Africa. A gridded water temperature data set was used as input to a bioenergetics model to predict number of crops per year for the following three species: Nile tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and Common carp (Cyprinus carpio). Similar analytical approaches to those by Kapetsky and Nath (1997) were followed in the yield estimation. However, different specifications were used for small-scale and commercial farming scenarios in order to reflect the types of culture practices found in Africa. Moreover, the fish growth simulation model, documented in Kapetsky and Nath (1997), was refined to enable consideration of feed quality and high fish biomass in ponds. The small-scale and commercial models derived from the land-quality evaluation were combined with the yield potential of each grid cell for each of the three fish species to show the coincidence of each land-quality suitability class with a range of yield potentials. Finally, the land quality-fish yield potential combinations were put together to show where the fish farming potential coincided for the three fish species."
