Download or read book Salinity and Water Stress written by M. Ashraf and published by Springer Science & Business Media. This book was released on 2008-12-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income. Presenting recent research findings on salt stress, water stress and stress-adapted plants, this book offers insights into new strategies for increasing the efficiency of crops under stressful environments. The strategies are based on conventional breeding and advanced molecular techniques used by plant physiologists, and are discussed using specific case studies to illustrate their potential. The book emphasizes the effects of environmental factors on specific stages of plant development, and discusses the role of plant growth regulators, nutrients, osmoprotectants and antioxidants in counteracting their adverse affects. Synthesising updated information on mechansisms of stress tolerance at cell, tissue and whole-plant level, this book provides a useful reference text for post graduate students and researchers involved in the fields of stress physiology and plant physiology in general, with additional readership amongst researchers in horticulture, agronomy, crop science, conservation, environmental management and ecological restoration.

Book excerpt: This open access book is an outcome of the collaboration between the Soil and Water Management & Crop Nutrition Section, Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, Department of Nuclear Sciences and Applications, International Atomic Energy Agency (IAEA), Vienna, Austria, and Dr. Shabbir A Shahid, Senior Salinity Management Expert, Freelancer based in United Arab Emirates.The objective of this book is to develop protocols for salinity and sodicity assessment and develop mitigation and adaptation measures to use saline and sodic soils sustainably. The focus is on important issues related to salinity and sodicity and to describe these in an easy and user friendly way. The information has been compiled from the latest published literature and from the authors’ publications specific to the subject matter. The book consists of six chapters. Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Download or read book Plant Salt Tolerance written by Sergey Shabala and published by Humana Press. This book was released on 2012-08-16 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil salinity is destroying several hectares of arable land every minute. Because remedial land management cannot completely solve the problem, salt tolerant crops or plant species able to remove excessive salt from the soil could contribute significantly to managing the salinity problem. The key to engineering crops for salt tolerance lies in a thorough understanding of the physiological mechanisms underlying the adaptive responses of plants to salinity. Plant Salt Tolerance: Methods and Protocols describes recent advances and techniques employed by researchers to understand the molecular and ionic basis of salinity tolerance and to investigate the mechanisms of salt stress perception and signalling in plants. With chapters written by leading international scientists, this book covers nearly 30 different methods, such as microelectrode and molecular methods, imaging techniques, as well as various biochemical assays. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Plant Salt Tolerance: Methods and Protocols serves as an essential read for every student or researcher tackling various aspects of the salinity problem.

Available in PDF, EPUB and Kindle. Book excerpt: The struggling states of Bihar and Mithila serve as extreme examples of India‘s problems. Development here has been thwarted by a hereditary landed aristocracy supported by religion, casteism, custom, social stratification, tradition, and patterns of behaviour that can be traced back millennia. In turn, all these have been masterfully manipulated by co-opted politicians, who have turned politics into a veritable art form as this volume comprehensively demonstrates.

This book was released on 2015-07-31 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 2009, more than 40,000 people died prematurely in Sindh, Pakistan because of an illness associated with an environmental health risk. This means that almost one of every five deaths that occurred that year was caused by environmental factors. Loss of natural resources and impacts from natural disasters also represent development challenges. Increased salinity and waterlogging result in loss of agricultural crops. In addition, hydro-meteorological hazards recurrently affect Sindh, as illustrated by the devastating effects of the 2010 and 2011 floods. For Sindh's population, these problems mean pain and suffering, and reduced opportunities for economic advancement. The costs of all these phenomena are equivalent to 10% of Sindh's Gross Domestic Product. Climate change may exacerbate these challenges. Sindh's environmental and climate change problems call for urgent responses. A number of feasible interventions could be carried out to address the categories of environmental degradation that have the highest impacts on Sindh's population. Many of those interventions have positive benefit-cost ratios, meaning that every rupee invested in them would result in health and social benefits worth more than one rupee. Addressing these challenges also calls for targeted institutional strengthening and policy improvements, particularly after the 18th Constitutional Amendment devolved environmental management responsibilities to provincial governments. The underlying goal of this book is to facilitate and stimulate sharing of information on these phenomena, and to provide an interdisciplinary framework for bringing about improved environmental conditions in Sindh. It includes a methodology that enables the identification of environmental and climate change priority problems; the analysis of interventions to address such problems; the establishment of a social learning mechanism to continuously improve Sindh's responses and build resilience in the face of climate variability and change; and opportunities for the potential involvement of different stakeholder groups to decisively tackle climate change and deteriorating environmental conditions.
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.
