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.

Book excerpt: This book offers the first multidisciplinary overview of water resources issues and management in the Aral Sea Basin, covering both the Amu Darya and Syr Darya River Basins. The two main rivers of Amu Darya and Syr Darya and their tributaries comprise the Aral Sea Basin area and are the lifeline for about 70 million inhabitants in Central Asia. Written by regional and international experts, this book critically examines the current state, trends and future of water resources management and development in this major part of the Central Asia region. It brings together insights on the history of water management in the region, surface and groundwater assessment, issues of transboundary water management and environmental degradation and restoration, and an overview of the importance of water for the key economic sectors and overall socio-economic development of Central Asian countries, as well as of hydro politics in the region. The book also focusses on the future of water sector development in the Basin, including a review of local and international actors, as well as an analysis of the current status and progress towards the Sustainable Development Goals by Basin countries. The book will be essential reading for those interested in sea basin management, environmental policy in Central Asia and water resource management more widely. It will also act as a reference source for decision-makers in state agencies, as well as a background source of information for NGOs.

Download or read book Transport in the Atmosphere Vegetation Soil Continuum written by Arnold F. Moene and published by Cambridge University Press. This book was released on 2014-01-31 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, soil science, atmospheric science, hydrology, plant science and agriculture have been studied largely as separate subjects. These systems are clearly interlinked, however, and in recent years a great deal of interdisciplinary research has been undertaken to better understand the interactions. This textbook was developed from a course that the authors have been teaching for many years on atmosphere-vegetation-soil interactions at one of the leading international research institutes in environmental science and agriculture. The book describes the atmosphere-vegetation-soil continuum from the perspective of several interrelated disciplines, integrated into one textbook. The text is interspersed with many student exercises and problems, with solutions included. It will be ideal for intermediate to advanced students in meteorology, hydrology, soil science, environmental sciences and biology who are studying the atmosphere-vegetation-soil continuum, as well as researchers and professionals interested in the observation and modelling of atmosphere-vegetation-soil interactions.

This book was released on 2014-12 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: EIR RELEASES ROAD-MAP TO THE NEW WORLD ECONOMIC ORDER: THE NEW SILK ROAD BECOMES THE WORLD LAND-BRIDGE EIR's comprehensive study of the progress of the Eurasian Land-Bridge project which Lyndon and Helga LaRouche have championed for over 20 years, has finally been completed. The official release date is Dec. 1. The 374-page report, entitled The New Silk Road Becomes the World Land-Bridge, '' is nothing less than a conceptual, and often physical, road-map'' to a New World Economic Order. This path is currently being charted by the nations of the BRICS (Brazil, Russia, India, China, and South Africa), who are leading a dynamic of global optimism toward real economic development, complete with new credit institutions and major high-technology projects for uplifting all mankind. After an introduction by Helga Zepp-LaRouche, the report lays out the "Metrics of Progress," based on the economic scientific principles developed by renowned physical economist Lyndon LaRouche. It then proceeds region by region, beginning with China and Russia, to present the stunning progress, and plans, which have been made toward the Eurasian Land-Bridge design that the Chinese government laid out in 1996, and other nations have begun to rally behind in recent years. The report, complete with many full-color maps of its featured development corridors, is available in paperback for $50 and hard cover bound for $75.

Download or read book Combating Desertification in Asia Africa and the Middle East written by G. Ali Heshmati and published by Springer Science & Business Media. This book was released on 2013-07-01 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the ‘how’ of desertification control as opposed to an analysis of the ‘why’ and fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands. There are numerous illustrations to show the successful techniques. This compilation demonstrates that desertification and land degradation can be controlled and reversed with existing techniques in such widely varying environments as the Sahel of Africa to Sri Lanka and the Philippines in SE Asia, from mountains in Lesotho to low lands on desert margins in Mongolia. Proven approaches include technical interventions, changes in governance and to the legislative framework and policy reform. The book fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands.
