This book was released on 2017 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Waterlogging and salinisation are major impediments to the sustainability of irrigated agriculture and livelihoods of farming families across the Indus Basin of Pakistan. About 6.3 million ha in Pakistan are affected by different levels and types of salinity. Nearly half of this area is under irrigated agriculture. The drive for higher cropping intensities coupled with the lack of adequate surface water supplies has caused farmers to use poor-quality groundwater as a supplemental source of irrigation. The large scale exploitation of poor quality groundwater has increased the risks of soil salinisation and sodicity. About 4.5 million ha are already affected by secondary salinisation of which about half are located in irrigated areas. Another 1 million ha is affected by water logging (Qureshi et al., 2008). In Punjab, about 20% of the land suffers from salinity and another 20 to 30% has high groundwater levels, due to over application of surface water. Soil salinity problems are particularly serious in Sindh province where some 70 to 80% of the soil is classified as moderately or severely saline (Smedema, 2000). The southern districts of Lower Sindh, Thatta and Badin are particularly vulnerable to salinity due to waterlogging and seawater intrusion in coastal agricultural areas. A holistic approach that incorporates the social, environmental, technical and economic aspects of salinity management is needed in Pakistan. Such an approach offers better prospects for identifying and exploring adaptation measures and building resilience for communities affected by salinity. This SRA has established the need for a holistic approach to salinity and water management, and has laid the basis for developing a shared understanding of the risks and opportunities for farming and coastal communities in salinity affected areas of the Indus Basin of Pakistan. Central to this is an understanding of the spatial and temporal dimensions of salinity in the landscape."--Website.

Book Synopsis Improvement of Plant Production in the Era of Climate Change by : Shah Fahad
Download or read book Improvement of Plant Production in the Era of Climate Change written by Shah Fahad and published by CRC Press. This book was released on 2022-07-20 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current trends in population growth suggest that global food production is unlikely to meet future demands under projected climate change scenarios unless the pace of plant improvement is accelerated. Plant production is facing many challenges due to changing environmental conditions and the growing demand for new plant-derived materials. These challenges come at a time when plant science is making significant progress in understanding the basic processes of plant growth and development. Major abiotic stresses like drought, heat, cold and salinity often cause a range of morphological, physiological, biochemical, and molecular changes affecting plant growth, development, and productivity; so sustainable food production poses a serious challenge to much of the world, particularly in emerging countries. This underscores the urgent need to find better ways to translate new advances in plant science into concrete successes in agricultural production. In order to overcome the negative effects of abiotic stress and to maintain food security in the face of these challenges, new, improved, and resilient plant varieties, contemporary breeding techniques, and a deep understanding of the mechanisms for offsetting harmful climate change are undoubtedly necessary. In this context, Improvement of Plant Production in the Era of Climate Change is a guide to the most advanced techniques that help in understanding plant response to abiotic stress, leading to new horizons and the strategy for the current translation studies application to overall solution to create a powerful production and crop improvement in such an adverse environment. FEATURES Provides a state-of-the-art description of the physiological, biochemical, and molecular-level understanding of abiotic stress in plants Courses taught in universities from basics to advanced level in field of plant physiology, molecular genetics, and bioinformatics will use this book Focuses on climatic extremes and their management for plant protection and production, which is great threat to future generation and food security Understanding of new techniques pointed out in this book will open the possibility of genetic engineering in crop plants with the concomitant improved stress tolerance Addressing factors that are threatening future food production and providing potential solutions to these factors Written by a diverse group of internationally famed scholars, this book adds new horizons in the field of abiotic stress tolerance
Book Synopsis Routledge Handbook of Environment and Society in Asia by : Paul G. Harris
Download or read book Routledge Handbook of Environment and Society in Asia written by Paul G. Harris and published by Routledge. This book was released on 2014-09-19 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowhere is the connection between society and the environment more evident and potentially more harmful for the future of the world than in Asia. In recent decades, rapid development of Asian countries with very large populations has led to an unprecedented increase in environmental problems such as air and water pollution, solid and hazardous wastes, deforestation, depletion of natural resources and extinction of native species. This handbook provides a comprehensive survey of the cultural, social and policy contexts of environmental change across East Asia. The team of international experts critically examine a wide range of environmental problems related to energy, climate change, air, land, water, fisheries, forests and wildlife. The editors conclude that, with nearly half of the human population of the planet, and several rapidly growing economies, most notably China, Asian societies will determine much of the future of human impacts on the regional and global environments. As climate change-related threats to society increase, the book strongly argues for increased environmental consciousness and action in Asian societies. This handbook is a very valuable companion for students, scholars, policy makers and researchers working on environmental issues in Asia.
Book Synopsis Management of Soil Problems by : Khan Towhid Osman
Download or read book Management of Soil Problems written by Khan Towhid Osman and published by Springer. This book was released on 2018-05-03 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are neither good nor bad, but some have inherent or acquired characteristics that may or may not suit our intended use. Unsuitable characteristics are considered to be soil problems, soil constraints or soil limitations. Only twelve percent of global land is right for agricultural production without much limitation. Some soils have severe limitations for crop production. These soils are so called ‘problem soils’. Many of them do not have enough fertility to be productive; some are arid and saline; some are very sandy and dry; and some are wet and waterlogged for most of the growing season. The global demand for food, wood, fuel, fiber, medicine and other plant products for the 7.2 billion current world population has created such an immense pressure on global soil resources that even the most fertile soils are losing their productive capacity. We are being compelled to bring more and more unsuitable or marginally suitable soils under cultivation. Unless innovative and integrated soil, crop and environmental management practices are adopted for their improvement and sustainable use, further degradation is inevitable. This book, Management of Soil Problems, identifies the problems and discusses management options in a smooth and reader-friendly style. It will be useful for students and professionals of soil science, agriculture, forestry, geography and environmental sciences.
Book Synopsis Strategies for the Management of Conjunctive Use of Surface Water and Groundwater Resources in Semi-arid Areas by : Asad Sarwar Qureshi
Download or read book Strategies for the Management of Conjunctive Use of Surface Water and Groundwater Resources in Semi-arid Areas written by Asad Sarwar Qureshi and published by IWMI. This book was released on 2004 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to inadequate rainfall, groundwater has acquired a vital role in the development of Pakistan's agricultural economy. However, a lack of awareness concerning the use of groundwater, either by itself or combined with canal water, has added large amounts of salt to the soil. As a result, large tracts of irrigated lands are already salinized, while many others are under threat. This report presents the results of a modeling study carried out to evaluate the long-term effects of a different quality of irrigation water on root zone salinity. The simulations were performed for the Rechna Doab (sub basin of the Indus Basin) in Pakistan, by using 15 years of actual rainfall and climatic data.

Download or read book The Indus Basin of Pakistan written by Winston H. Yu and published by World Bank Publications. This book was released on 2013 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

This book was released on 2024-08-29 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change not only involves rising temperatures but it can also alter the hydro-meteorological parameters of a region and the corresponding changes emerging in the various biotic or abiotic environmental features. One of the results of climate change has been the impact on the sediment yield and its transport. These changes have implications for various other environmental components, particularly soils, water bodies, water quality, land productivity, sedimentation processes, glacier dynamics, and risk management strategies to name a few. This volume provides an overview of the fundamental processes and impacts of climate change on river basin management and examines issues related to soil erosion, sedimentation, and contaminants, as well as rainfall-runoff modeling and flood mitigation strategies. It also includes coverage of climate change fundamentals as well as chapters on related global treaties and policies.

Book Synopsis Integrated Groundwater Management by : Anthony J Jakeman
Download or read book Integrated Groundwater Management written by Anthony J Jakeman and published by Springer. This book was released on 2016-08-05 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.
