The Inter Relationship Between Irrigation Drainage And The Environment In The Aral Sea Basin

The irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

This encyclopedia is the most comprehensive and up-to-date source of reference for sustainability in business and management. It covers both traditional and emerging concepts and terms and is fully international in its scope. More than 700 contributions of internationally renowned experts provide a definitive access to the knowledge in the area of sustainable and responsible management. All actors in the field will find reliable and up to date definitions and explanations of the key terms and concepts of management in this reference work. The Encyclopedia of Sustainable Management represents all aspects of management and business conduct. It takes sustainability as a management concept that gives due credit to the complexity and diverging constraints in which businesses and corporations act today, and it emphasizes and focuses approaches that help ensure that today's management decisions and actions will be the basis for tomorrow's prosperity.

Water and Environment addresses imbalances between availability and demand, degradation of surface and ground waters, inter-sectorial, inter-regional and international competition in water management. With contributions from internationally distinguished experts at the first Inter-Regional Conference on Environment-Water: Innovative Issues in Irrig

As demand for fresh water rises, together with population, water scarcity already features on the national security agenda of many countries. In this book, Dinardevelops a theory to explain solutions to property rights conflicts over shared rivers. Through systematic analysis of available treaty texts, corresponding side-payment and cost-sharing patterns are gleaned. Geographic and economic variables are used to explain recurring property rights outcomes. Rather than focusing on a specific river or particular geographic region, the book analyzes numerous rivers, dictated by the large number of treaty observations, and is able to test several hypotheses, devising general conclusions about the manner in which states resolve their water disputes. Policy implications are thereby also gained. While the book simultaneously considers conflict and cooperation along international rivers, it is the focus on negotiated agreements, and their embodied side-payment and cost-sharing regimes, that justifies the use of particular independent variables.

Radionuclides produced by past nuclear weapon test explosions comprise the largest source of anthropogenic radioactivity released into the earth's atmosphere to date. This volume presents data and models about the fate of the released radionuclides and their possible effects on human health. It is divided into the following three parts: - Source Term Studies; - Dose Reconstruction; - Ecological and Health Effects, and comprises both Western and formerly secret Soviet research studies, illuminates past and current research.

This volume focuses on the human exposures and medical effects studies in the SemipaiatinskJ Altai region of Siberia that were a consequence of the radioactive fallout from nuclear test explosions that took place at the Semipalatinsk Test Site of the former Soviet Union. It contains a detailed account of a NATO Advanced Research Workshop (ARW) devoted to the subject, and a selection of the papers presented. The title of the ARW was "Long-term Consequences of Nuclear Tests for the Environment and Population Health (SemipaiatinskJAltai Case Studies)". The estimated exposures to large numbers of people in the Altai lie in an important dose rate and dose domain. Hence the research reported herein provides new and unique information on the effects of radiation on humans. Also emphasized at the ARW were studies involving fallout from the Pacific Island tests of the U. S. A . . There have been over 2300 nuclear weapon test explosions to date. More than 500 took place in the atmosphere and outer space; the remainder were underground. The atmospheric tests comprise the largest source of anthropogenic radioactivity released into the earth's atmosphere to date. The vast majority, in number and yield, were carried out by the former Soviet Union (FSU) and the United States. Each superpower maintained two primary test sites, one continental primarily for small yield tests, and the other more remote for larger yield tests. For the U. S. A.
