Download or read book Tropical Resources written by Jose I. Furtado and published by Routledge. This book was released on 2019-09-18 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1990 Tropical Resources presents in-depth coverage of the extremely diverse tropical environments, the resources to be found within the region and their production, and ecological management. The book discusses economic geography and ways of utilizing available resources, including those of tropical forests, wildlife, tidal wetlands and the sea. The book also include chapters on the development and land use of protected areas, the ecological aspects of pasture resources; and the impacts of economic development and population damage. In addition, studies are offered on tropical soils, including their distribution properties and management and the ecological processes at work in tropical forests. For geographers, economists and policymakers, the book provides a wealth of information on tropical resources and their potential development.
Book Synopsis A Strategic Reassessment of Fish Farming Potential in Africa by : José Aguilar-Manjarrez

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."

Download or read book The Attempt to Stay written by Valerie Hänsch and published by Berghahn Books. This book was released on 2024-08-01 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of the Merowe Dam along the Nile in northern Sudan flooded local villages and forced thousands of inhabitants to flee to higher ground. Despite the radical social and environmental transformations and an uncertain future, the Manasir have tried to continue their peasant way of life and resisted relocating to state-run resettlement schemes. Rather than focusing on migration and resettlement, the author follows the people’s attempts to preserve their homeland and have meaningful lives along the emerging reservoir. The book grapples with the fundamental question of how to re-establish life in a world that is falling apart.

Download or read book Agricultural Compendium written by Euroconsult (Organization) and published by . This book was released on 1989-04 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like its predecessors, this third revised edition of the Agricultural Compendium is packed with a wealth of statistical and general information about almost every aspect of agriculture in the tropics and subtropics. "Anyone in tropical rural development, whether in a technical capacity or as an economist/planner making use of technical results, would both save themselves time and increase their understanding and efficiency through possession of this compendium. It is not only a reference volume but potentially a major contribution to mutual understanding and therefore communication between different disciplines." commented Soil Survey and Land Evaluation after the publication of an earlier edition. Numerous sections (e.g. Chapter 7, Part B - Fisheries) and even complete chapters (e.g. Chapter 3, Geodosy; Chapter 10, Sociology) have been rewritten for the present edition. A number of new sections have also been added (e.g. in Chapter 3, a section on remote sensing techniques). Furthermore, in view of the now common use of scientific pocket calculators and personal computers, a number of graphs have been replaced by the original formulae.
