This book was released on 1998 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: "(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."

This book was released on 2006 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Socio Ecological Dimensions of Infectious Diseases in Southeast Asia written by Serge Morand and published by Springer. This book was released on 2015-07-07 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book pursues a multidisciplinary approach in order to evaluate the socio-ecological dimensions of infectious diseases in Southeast Asia. It includes 18 chapters written by respected researchers in the fields of history, sociology, ecology, epidemiology, veterinary sciences, medicine and the environmental sciences on six major topics: (1) Infectious diseases and societies, (2) Health, infectious diseases and socio-ecosystems; (3) Global changes, land use changes and vector-borne diseases; (4) Monitoring and data acquisition; (5) Managing health risks; and (6) Developing strategies. The book offers a valuable guide for students and researchers in the fields of development and environmental studies, animal and human health (veterinarians, physicians), ecology and conservation biology, especially those with a focus on Southeast Asia.

Download or read book Anthropology Art and Aesthetics written by Jeremy Coote and published by Oxford University Press. This book was released on 1992 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anthropology of art is a fast-developing area of intellectual debate and academic study. This beautifully illustrated volume is a unique survey of the current state of anthropological thinking on art and aesthetics. The distinguished contributors draw on contemporary anthropological theory and on classic anthropological topics such as myth and ritual to deepen our understanding of particular aesthetic traditions in their socio-cultural and historical contexts. Many of the essays present new findings based on recent field research in Australia, New Guinea, Indonesia, and Mexico; while others draw on classical anthropological accounts of the Trobriand Islanders of Melanesia and the Nuer of the Southern Sudan to form new arguments and conclusions. The introductory overview of the history of the anthropology of art, by Sir Raymond Firth, makes this volume especially useful for those interested in learning what anthropology has to contribute to our understanding of art and aesthetics in general.
