Download or read book Water Requirements for Irrigation and the Environment written by Marinus G. Bos and published by Springer Science & Business Media. This book was released on 2008-11-23 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.

Download or read book Plant Abiotic Stress Tolerance written by Mirza Hasanuzzaman and published by Springer. This book was released on 2019-04-04 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, “system biology” and “omics approaches” in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.

Download or read book Living Architecture Living Cities written by Christopher Day and published by Routledge. This book was released on 2019-11-08 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: It’s widely accepted that our environment is in crisis. Less widely recognized is that three quarters of environmental damage is due to cities – the places where most of us live. As this powerful new book elucidates, global sustainability is therefore directly dependent on urban design. In Living Architecture, Living Cities Christopher Day and Julie Gwilliam move beyond the current emphasis on technological change. They argue that eco-technology allows us to continue broadly as before and only defers the impending disaster. In reality, most negative environmental impacts are due to how we live and the things we buy. Such personal choices often result from dissatisfaction with our surroundings. As perceived environment has a direct effect on attitudes and motivations, improving this can achieve more sustainable lifestyles more effectively than drastic building change – with its notorious performance-gap limitations. As it’s in places that our inner feelings and material reality interact, perceived environment is place-based. Ultimately, however, as the root cause of unsustainability is attitude, real change requires moving from the current focus on buildings and technology to an emphasis on the non-material. Featuring over 400 high quality illustrations, this is essential reading for anyone who believes in the value and power of good design. Christopher Day’s philosophy will continue to inspire students with an interest in sustainable architecture, urban planning and related fields.

This book was released on 2019-10-01 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: As sessile organisms, plants have to cope with a multitude of natural and anthropogenic forms of stress in their environment. Due to their longevity, this is of particular significance for trees. As a consequence, trees develop an orchestra of resilience and resistance mechanisms to biotic and abiotic stresses in order to support their growth and development in a constantly changing atmospheric and pedospheric environment. The objective of this Special Issue of Forests is to summarize state-of-art knowledge and report the current progress on the processes that determine the resilience and resistance of trees from different zonobiomes as well as all forms of biotic and abiotic stress from the molecular to the whole tree level.

Download or read book The Inter Relationship Between Irrigation Drainage and the Environment in the Aral Sea Basin written by M.G. Bos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Irrigation Water Pricing written by François Molle and published by CABI. This book was released on 2007-01-01 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much hope has been vested in pricing as a means of helping to regulate and rationalize water management, notably in the irrigation sector. The pricing of water has often been applied universally, using general and ideological policies, and not considering regional environmental and economic differences. Almost 15 years after the emphasis laid at the Dublin and Rio conferences on treating water as an economic good, a comprehensive review of how such policies have helped manage water resources an irrigation use is necessary. The case-studies presented here offer a reassessment of current policies by evaluating their objectives and constraints and often demonstrating their failure by not considering the regional context. They will therefore contribute to avoiding costly and misplaced reforms and help design water policies that are based on a deeper understanding of the factors which eventually dictate their effectiveness.
