Download or read book Terrestrial Ecoregions of Africa and Madagascar written by and published by . This book was released on 2004 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a global effort to identify those areas where conservation measures are needed most urgently, World Wildlife Fund has assembled teams of scientists to conduct ecological assessments of all five continents. Terrestrial Ecoregions of Africa and Madagascar is the latest contribution, presenting in a single volume the first comprehensive assessment of biodiversity patterns, threats to biodiversity, and resulting conservation priorities across the African continent and its islands. Looking at biodiversity and threats in terms of biological units rather than political units, the book offers a comprehensive examination of African biodiversity across all biomes and multiple taxonomic groups. In addition to the seven main chapters, the book includes twenty essays by regional experts that provide more depth on key issues, as well as nine detailed appendixes that present summary data used in the analyses, specific analytical methodologies, and a thorough text description for each of Africa's 119 terrestrial ecoregions. Terrestrial Ecoregions of Africa and Madagascar provides a blueprint for conservation action and represents an unparalleled guide for investments and activities of conservation agencies and donor organizations.

Download or read book Building Resilience to Climate Change written by Angela Andrade Pérez and published by IUCN. This book was released on 2010 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: With climate change now a certainty, the question is how much change there will be and what can be done about it. One of the answers is through adaptation. Many of the lessons that are being learned in adaptation are from success stories from the field. This publication contains eleven case studies covering different ecosystems and regions around the world. Its aim is to summarize some current applications of the Ecosystem-Based Adaptation concept and its tools used around the world, and also draw lessons from experiences in conservation adaptation.

Download or read book Toward Climate Resilient Development in Nigeria written by Raffaello Cervigni and published by World Bank Publications. This book was released on 2013-08-05 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: If not addressed in time, climate change is expected to exacerbate Nigeria’s current vulnerability to weather swings and limit its ability to achieve and sustain the objectives of Vision 20:2020 [as defined in http://www.npc.gov.ng /home/doc.aspx?mCatID=68253]. The likely impacts include: • A long-term reduction in crop yields of 20–30 percent • Declining productivity of livestock, with adverse consequences on livelihoods • Increase in food imports (up to 40 percent for rice long term) • Worsening prospects for food security, particularly in the north and the southwest • A long-term decline in GDP of up to 4.5 percent The impacts may be worse if the economy diversifies away from agriculture more slowly than Vision 20:2020 anticipates, or if there is too little irrigation to counter the effects of rising temperatures on rain-fed yields. Equally important, investment decisions made on the basis of historical climate may be wrong: projects ignoring climate change might be either under- or over-designed, with losses (in terms of excess capital costs or foregone revenues) of 20–40 percent of initial capital in the case of irrigation or hydropower. Fortunately, there is a range of technological and management options that make sense, both to better handle current climate variability and to build resilience against a harsher climate: • By 2020 sustainable land management practices applied to 1 million hectares can offset most of the expected shorter-term yield decline; gradual extension of these practices to 50 percent of cropland, possibly combined with extra irrigation, can also counter-balance longer-term climate change impacts. • Climate-smart planning and design of irrigation and hydropower can more than halve the risks and related costs of making the wrong investment decision. The Federal Government could consider 10 short-term priority responses to build resilience to both current climate variability and future change through actions to improve climate governance across sectors, research and extension in agriculture, hydro-meteorological systems; integration of climate factors into the design of irrigation and hydropower projects, and mainstreaming climate concerns into priority programs, such as the Agriculture Transformation Agenda.
Download or read book Economic Valuation of Water Resources in Agriculture written by R. Kerry Turner and published by Food & Agriculture Org.. This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to produce a review on water resource valuation issues and techniques specifically for the appraisal and negotiation of raw (as opposed to bulk or retail) water resource allocation for agricultural development projects. The review considers raw water in naturally occurring watercourses, lakes, wetlands, soil and aquifers, taking an ecosystem function perspective at a catchment scale, and takes account of the demands from irrigated and rainfed agriculture. It is hoped that the review will have particular application to developing countries where agreed methods for reconciling competing uses are often absent, but nevertheless takes account of valuation approaches that have been made in post industrial economies.
Download or read book Collaboration Across Boundaries for Social Ecological Systems Science written by Stephen G. Perz and published by Springer. This book was released on 2019-03-30 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collaboration across boundaries is widely recognized as a vital requisite for the advancement of innovative science to address problems such as environmental degradation and global change. This book takes collaboration across boundaries seriously by focusing on the many challenges and practices involved in team science when spanning disciplinary, organizational, national and other divides. The authors draw on a shared framework for managing the challenges of collaboration across boundaries as applied to the science of understanding complex social-ecological systems. Teams working across boundaries on diverse social-ecological systems in countries around the world report their challenges and share their practices, outcomes and lessons learned. From these diverse experiences arise many commonalities and also some important differences. These provide the basis for a set of recommendations to any collaborators intending to use science as a tool to better understand social-ecological systems and to improve their management and governance.
Download or read book Wetlands agriculture and poverty reduction written by McCartney, Matthew and published by IWMI. This book was released on 2010 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.

The observations and measurements of environmental change help gauge the extent of progress made by African countries towards reaching the United Nation's Millennium Development Goals. More importantly, this book contributes to the knowledge and understanding that are essential for adaptation and remediation, and should be of immense value to all those who want to know more about Africa and who care about the future of this continent.
Download or read book The Future of Large Dams written by Thayer Ted Scudder and published by Earthscan. This book was released on 2012 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viewed by some as symbols of progress and by others as inherently flawed, large dams remain one of the most contentious development issues on Earth. Building on the work of the now defunct World Commission on Dams, Thayer Scudder wades into the debate with unprecedented authority.Employing the Commission's Seven Strategic priorities, Scudder charts the 'middle way' forward by examining the impacts of large dams on ecosystems, societies and political economies. He also analyses the structure of the decision-making process for water resource development and tackles the highly contentious issue of dam-induced resettlement, illuminated by a statistical analysis of 50 cases.
Download or read book Wetland Ecosystems written by William J. Mitsch and published by John Wiley & Sons. This book was released on 2009-04-13 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.
Download or read book Riparian Landscapes written by George Patrick Malanson and published by Cambridge University Press. This book was released on 1993-05-27 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The specific spatial pattern of riparian vegetation is seen as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. Riparian structures are controlled by the spatial dynamics of channels, flooding and soil moisture. These dynamics are part of integrated cascades of water, sediment, nutrients and carbon, to which animal and plant species respond in ways that illuminate community structure and competition. The role of the riparian zone in controlling species distribution and abundance is discussed. Intelligent management of these valuable ecological resources is highlighted. The potential for linking hydrological, geomorphological and ecological simulation models is also explored. This book will be of interest to graduate and professional research workers in environmental science, ecology and physical geography.
