Book Synopsis Climate Change and Africa by : Pak Sum Low
Download or read book Climate Change and Africa written by Pak Sum Low and published by Cambridge University Press. This book was released on 2006-11-02 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the twenty-first century, no environmental issue is of such truly global magnitude as the issue of climate change. The poorer, developing countries are the least equipped to adapt to the potential effects of climate change, although most of them have played an insignificant role in causing it. African countries are amongst the poorest of the developing countries. This book presents the issues of most relevance to Africa, such as past and present climate, desertification, biomass burning and its implications for atmospheric chemistry and climate, energy generation, sea-level rise, ENSO-induced drought and flood, adaptation, disaster risk reduction, the UNFCCC and Kyoto Protocol (especially the Clean Development Mechanism), capacity-building, and sustainable development. It provides a comprehensive and up-to-date review of these and many other issues, with chapters by the leading experts from a range of disciplines. Climate Change and Africa will prove to be an invaluable reference for all researchers and policy makers with an interest in climate change and Africa.

Download or read book Global Environmental Change and Land Use written by Han Haarman and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction between environmental change and human activities is com plex, requiring the concepts and tools of a number of disciplines for its effective analysis. Land-use and land-cover change has only recently become a topic susceptible to scientific research, as these concepts and tools have been devel oped and made available. Rooted in a broad community concemed with global change, systematic research has begun into land-use systems at different scales and interactions, and their links with global cyc1es of water, nitrogen and carbon are being explored. Partly based on research initiated by the Dutch National Research Programme on Global Air PolIution and Climate Change (NRP), this book touches upon various land-use and land-cover issues in relation to global environmental change. In addition to the biogeochemical cyc1es, land as a car rier for functions of economic activities, food and fibre production and energy production via biomass are discussed. Crucial in studying land use is human behaviour and man-environment interaction at different scales. Land-use and land-cover change is an important contrlbutor of greenhouse gasses as these activities directly interfere with the carbon, nitrogen and water cyc1es. These cyc1es are connected through numerous feedback loops. The interface of land-use and c1imate is essentially determined by the interaction of man and the environment. Man uses land primarily to produce food; a relatively small area is needed for urban development.

Book Synopsis Sustainable land management and its effects on water security and poverty: Evidence from a watershed intervention program in Ethiopia by : Kato, Edward
Download or read book Sustainable land management and its effects on water security and poverty: Evidence from a watershed intervention program in Ethiopia written by Kato, Edward and published by Intl Food Policy Res Inst. This book was released on 2019-03-05 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the impacts of sustainable land management (SLM) on water security and poverty based on an evaluation of a watershed level SLM program promoted in Amhara regional state of Ethiopia. A household survey was conducted in two WLRC watersheds with SLM programming as well as complementary support and two adjacent watersheds without such programming. Our findings show that the SLM program significantly increased plot-level adoption of SLM practices, particularly of soil bunds and stone terraces. We also find that SLM contributes to water security for both crop and livestock production. Households in SLM-supported learning watersheds have more access to groundwater for irrigation and have higher crop yields for maize, mango and millet; have experienced improving water availability for livestock production in the past five years; and have higher income from livestock products than households in control watersheds. The positive impacts of SLM and complementary interventions on livestock income is attributed to the improved water security conditions in the learning watersheds, access to better animal forage planted along the SLM constructed structures, and animal vaccination and artificial insemination services that were part of the broader set of interventions. These findings further show that although SLM impacts were limited, the potential to improve welfare of smallholders across several livelihoods is enhanced when SLM is combined with other multifaceted complimentary interventions.

Book Synopsis Potential Impacts of Climate Change on Tropical Forest Ecosystems by : Adam Markham
Download or read book Potential Impacts of Climate Change on Tropical Forest Ecosystems written by Adam Markham and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change represents one of the most alarming long-term threats to ecosystems the world over. This new collection of papers provides, for the first time, an overview of the potentially serious impact that climate change may have on tropical forests. The authors, a multi-disciplinary group of leading experts in climatology, forestry, ecology and conservation biology, present a state-of-knowledge snapshot of how tropical forests are likely to react to the changes being wrought on our planet's atmosphere and climate. Tropical forests represent extraordinary harbours for biological diversity, and yet as deforestation and degradation continue apace, they are under greater pressure from human impacts than ever before. Climate change adds yet another threat to these valuable ecosystems, and this volume demonstrates just how significant a problem this may really be. The authors identify certain types of forest, including tropical montane cloud forest that may be particularly vulnerable. They also show the strong likelihood of global warming aggravating problems in already fragmented forest areas.

Book Synopsis Estimation of Evapotranspiration Rates in Irrigated Lands of the Fergana Valley using Stable Isotopes by : Gulomjon Umirzakov
Download or read book Estimation of Evapotranspiration Rates in Irrigated Lands of the Fergana Valley using Stable Isotopes written by Gulomjon Umirzakov and published by Cuvillier Verlag. This book was released on 2016-03-30 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in Uzbekistan critically depends on water resources availability, therefore crop production, especially of cotton and winter wheat, is restricted mainly to irrigated areas. As a result of water shortage under climate change, land degradation issues in the region worsened and water use efficiency has considerably decreased over the decades. Hence, it is essential to investigate water balance parameters in irrigated lands. Environmental isotopes have been widely applied in hydrological investigations, particularly estimation of evapotranspiration rate, one of the main components of the water balance in irrigated lands. This study aims to estimate evapotranspiration rates in cotton fields by applying water stable isotopes (2H and 18O). The study is based on the field experiments conducted during the vegetation periods 2010 and 2011 in the Fergana Region of Uzbekistan. Soil for isotope analysis were sampled in a sandy field, sandy loam #1 field (rich with gypsum) and sandy loam #2 field (without gypsum). The soil water from the samples was extracted by the cryogenic extraction method. δ2H and δ18O ratios of extracted water were determined using the laser spectroscopy method. Evapotranspiration rates were estimated with the isotope mass balance model. Besides evapotranspiration estimation, this study examines the variability and characteristics of stable isotope signatures of different water sources in the study region and analyzes water extraction processes from different soil types and temporal changes of isotope signatures through the depth in irrigated cotton fields.
