Download or read book The Earth Remains Forever written by Rob Jackson and published by University of Texas Press. This book was released on 2010-07-05 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Writing especially for people who've tuned out the environmental debate, Rob Jackson persuasively argues that we're at a crucial turning point in environmental history, where choices we make now will determine the quality of life into the unforeseeable future. Laying out the scientific facts in plain language and with flashes of humor, he shows how the escalation of population growth and resource consumption in the twentieth century caused problems from ozone depletion to global warming, habitat destruction, and biodiversity loss. At the same time, however, he highlights ongoing solutions to these problems and ways in which we can create a sustainable future for subsequent generations and all life on earth. His urgent message is not that we've already failed, but that we can succeed.
Download or read book The economics of biological invasions written by Charles Perrings, Silvana Dalmazzone, Mark Herbert Williamson and published by Edward Elgar Publishing. This book was released on 2000-08-25 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

Download or read book Limnology Climatology and Paleoclimatology of the East African Lakes written by Thomas C Johnson and published by Routledge. This book was released on 2019-08-13 with total page 679 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Download or read book Structural Adjustment and Socio economic Change in Sub Saharan Africa written by Peter Gibbon and published by Nordic Africa Institute. This book was released on 1996 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarises the results of work at the Nordiska Afrikainstitutet/Nordic Africa Institute (NAI) on the impact of structural adjustment implementation on the economies, states and societies of sub-Saharan Africa. It consists of two essays and an appendix listing research projects which have been/are being carried out under the auspices of NAI. The first essay raises a series of conceptual and methodological questions in the context of a presentation of some of the main empirical results obtained from extended field work carried out during the course of 1992 and 1993 in Kenya, Tanzania and Zimbabwe. The second essay presents the three main themes - private trading networks and structures, the changing political economy of land, and popular forms of social provisioning - that constitute the core of the second phase of NAI's structural adjustment research and, in so doing, provides a review of aspects of the adjustment literature. This report is, therefore, an attempt both at stock-taking and agenda-building as part of a wider quest for deepening our understanding of the structures and processes of socio-economic change associated with the crisis and adjustment years in contemporary Africa

This book was released on 1993 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven country case studies of fish marketing and distribution patterns are presented in this collection. Country studies of Burundi, Lesotho, Malawi, Tanzania, Uganda, Zambia, and Zimbabwe were prepared in accordance with a recommendation of the Technical Consultation on Aquaculture and Human Nutrition (Maseru, Lesotho, 5-8 June 1989). The selected countries represent a considerable range of circumstances in terms of such dimensions as territorial extent, access to marine or freshwater resources, domestic production capcities, and traditions of fisheries and fish consumption. An introductory overview chapter provides a summary account based on the format used for each of the case presentations, and sets out general recommendations for further development action on a region-wide basis.
