Attempts to describe the water situation in India at a national level are often misleading due to the tremendous diversity in the water situation across the country. This Report analyzes the spatial variation of water supply and demand across river basins in India. The study identifies basins that are water-scarce because of inadequate water availability to meet the effective demand. It also identifies issues that are important for estimating the future water demand and for the formation of policy for future water-resources development and management.

Book excerpt: This report describes the development of the near real-time drought monitoring and reporting system for the region, which currently includes Afghanistan, Pakistan and western parts of India. The system is based on drought-related indices derived from high-resolution remote-sensing data (MODIS). The unique feature of the study is the development of regression relationships between drought-related indices obtained from MODIS and AVHRR data, which have different pixel-resolution and optical characteristics. The goal is to make the system available, via Internet, to all stakeholders in the region.

This book was released on 2005 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reports on a form of multi-criteria analysis that provides a formal approach for evaluating the suitability of a wetland for specific agricultural uses, and ensures that explicit consideration is given to the possible consequences of such utilization. The method is based on a hybrid of ideas taken from concepts and methodologies related to: environmental flow assessments, land suitability classification and the hazard evaluation procedures used in the design of dams. The approach, which elaborates the idea of working wetlands, is generic, though the examples presented are for case studies from southern Africa.

This book was released on 2005 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the dissolution of the former Soviet Union and the collapse of existing trade arrangements, the newly independent states of Central Asia were left with the task of developing their own independent market economies. The region has undergone tremendous economic and social changes including significant agricultural reform mainly targeted at privatizing large collective farms that were established during the Soviet era. These reforms include the establishment of smaller private and cooperative farms in order to improve the efficiency and equity of existing production systems. Within Uzbekistan, this move to privatize farms has, in the majority of cases, led to declining productivity and net incomes. However, there have been instances where privatized farms and smaller collectives have been able to capitalize on these changes and perform at levels exceeding the norm. This Report identifies the key attributes of these successful farms that have been termed ''bright'' spots.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone’s health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil Examines the challenges and possibilities towards the various phytoremediation candidates Includes the latest research and ongoing progress in phytoremediation

Book excerpt: The books provides a timely analysis in support of a paradigm shift in the field of wastewater management, from ‘treatment for disposal’ to ‘treatment for reuse’ by offering a variety of value propositions for water, nutrient and energy recovery which can support cost savings, cost recovery, and profits, in a sector that traditionally relies on public funding. The book provides new insights into the economics of wastewater use, applicable to developed and developing countries striving to transform wastewater from an unpleasant liability to a valuable asset and recasting urbanization from a daunting challenge into a resource recovery opportunity. “It requires business thinking to transform septage and sewage into valuable products. A must read for water scholars, policy makers, practitioners, and entrepreneurs". Guy Hutton, Senior Economist, Water and Sanitation Program, Water Global Practice, World Bank “This book provides compelling evidence and real solutions for the new ‘resource from waste’ approach that is transforming sanitation, boosting livelihoods, and strengthening urban resilience”. Christopher Scott, Professor and Distinguished Scholar, University of Arizona “This book shows how innovative business thinking and partnerships around resource recovery and reuse fit well within an inclusive green economy and climate change adaptation and mitigation strategies”. Akiça Bahri, Coordinator of the African Water Facility, Tunisia, and award-winning researcher

Book excerpt: Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development. Published with IWMI.
