Available in PDF, EPUB and Kindle. Book excerpt: A multi-country research initiative to understand poverty from the eyes of the poor, the Voices of the Poor project was undertaken to inform the World Bank's activities and the upcoming World Development Report 2000/01. The research findings are being published in three books: "Can Anyone Hear Us?" gathers the voices of over 40,000 poor women and men in 50 countries from the World Bank's participatory poverty assessments (Deepa Narayan, Raj Patel, Kai Schafft, Anne Rademacher, and Sarah Koch-Schulte, authors). "Crying Out for Change" pulls together new field work conducted in 1999 in 23 countries (Deepa Narayan, Robert Chambers, Meera Shah, and Patti Petesch, authors). "From Many Lands" offers regional patterns and country case-studies (Deepa Narayan and Patti Petesch, editors). Voices of the Poor marks the first time such an exercise has been undertaken in so many developing countries and transition economies around the world. It provides a unique and detailed picture of the life of the poor and explains the constraints poor people face to escape from poverty in a way that more traditional survey techniques do not capture well. Each of the three volumes demonstrates the importance of voice and power in poor people's definition of poverty. Voices of the Poor concludes that we need to expand our conventional views of poverty which focus on income expenditure, education, and health to include measures of voice and empowerment.

Available in PDF, EPUB and Kindle. Book excerpt: Deforestation is occurring at an alarming rate in many parts of the world, causing destruction of natural habitat and fragmentation of what remains. Nowhere is this problem more pressing than in the Amazon rainforest, which is rapidly vanishing in the face of enormous pressure from humans to exploit it. This book presents the results of the longest-running and most comprehensive study of forest fragmentation ever undertaken, the Biological Dynamics of Forest Fragments Project (BDFFP) in central Amazonia, the only experimental study of tropical forest fragmentation in which baseline data are available before isolation from continuous forest took place.A joint project of Brazil’s National Institute for Research in Amazonia and the U.S. Smithsonian Institution, the BDFFP has investigated the many effects that habitat fragmentation has on plants, invertebrates, and vertebrates. The book provides an overview of the BDFFP, reports on its case studies, looks at forest ecology and tree genetics, and considers what issues are involved in establishing conservation and management guidelines.

Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.

This book was released on 2000-01-01 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryophytes are of great importance in their ecosystems and for human well-being. They stabilize soil crust through colonization of bare grounds and rocks; they are essential in nutrient recycling, biomass production, and carbon fixing; they control water through an effective retention mechanism; and they have economic value as peat for fuel, horticulture, oil absorption, and as sources of a wide variety of chemical compounds. Bryophytes have long been used for medicinal purposes and provide a food source for reindeer, geese, ducks, sheep, musk-ox, lemmings, and other rodents. Threats include deforestation, cultivation of forests, reclamation of land, urbanization, roads, dam-building, mining, drainage of wetlands and over-grazing. This plan reviews the situation worldwide and proposes a variety of initiatives. It is aimed at those who work with and care about nature conservation, including governmental and non-governmental organizations as well as politicians and the general interested public.
