Available in PDF, EPUB and Kindle. Book excerpt: Globally, most food is produced using soil moisture that comes from precipitation (i.e., "green" water). Moreover, most of the water that reaches plants in irrigated systems also stems from precipitation. Despite this, irrigation (or "blue") water has typically been the focus for policy analysis, largely because it is possible for humans to manipulate blue water. This paper analyzes alternative water futures using a combined green and blue water accounting framework embedded within the water simulation components of IFPRI's International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). Future scenarios recently developed for the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD) and other studies are assessed with respect to this adjusted green/blue water accounting framework. The results reveal that accounting explicitly for green water resources broadens the scope of options for decision-makers who are seeking to improve agricultural production in the face of rising food and energy prices, a degrading water and land resource base, and increasing demands. This analysis highlight the importance of green/blue water accounting and presents a wider range of agricultural science and technology policy options for increasing global crop productivity across a span of potential futures.

Available in PDF, EPUB and Kindle. Book excerpt: In Iran, climate change combined with low adaptation capacity has an unparalleled impact on eco-systems as well as human livelihoods. The Roodasht region, in the lower part of the Zayandeh Rud basin in Central Iran, is severely affected by water scarcity, desertification and land degradation. This book describes the effects this has on the environment and society, analyzes the degree of vulnerability and suggests possible ways to improve land and water management. This book provides comprehensive and interdisciplinary insights into the environmental and social situation in the region, as well as possible solutions to deal with the current challenges. Written by German and Iranian scientists, NGO staff and government officials and bridging the gap between research and practical implementation, the book not only enhances our understanding of climate change and desertification, but also raises public awareness and promotes knowledge transfer between disciplines.

This book was released on 2009-02-05 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for an in-depth Policy and Institutional Studies to be done as part of the Upstream-Downstream Research project.

Available in PDF, EPUB and Kindle. Book excerpt: This paper analyzes the effects of climate change on hydrology and water resources in the Limpopo River Basin of Southern Africa, using a semidistributed hydrological model and the Water Simulation Module of the International Model for Policy Analysis of Agricultural Commodities and Trade (IMPACT). The analysis focuses on the effects of climate change on hydrology and irrigation in parts of the four riparian countries within the basin: Botswana, Mozambique, South Africa, and Zimbabwe. Results show that water resources of the Limpopo River Basin are already stressed under today's climate conditions. Projected water management and infrastructure changes are expected to improve the situation by 2030 if current climate conditions continue into the future. However, under the four climate change scenarios studied here, water supply situations are expected to worsen considerably by 2030. Assessing hydrological impacts of climate change is crucial given that expansion of irrigated areas has been postulated as a key adaptation strategy for Sub-Saharan Africa. Such expansion will need to take into account future changes in water availability in African river basins.

Download or read book The Economics of Water Management in Southern Africa written by Glenn-Marie Lange and published by Edward Elgar Publishing. This book was released on 2007-01-01 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a valuable new tool for water management water resource accounting which significantly advances the economic analysis of water. Water resource accounts integrate detailed information about water supply and use with national income accounts to show the economic use of water, costs and tariffs paid, and the economic value of water for different economic uses. Based on the UN s handbook for environmental accounting, this book describes the implementation and policy application of water accounts in three African countries Botswana, Namibia and South Africa and discusses how they have been used by water managers. The book compares water use across the three countries, explaining the differences in water resources and water policy. In addition to the comprehensive outline of physical and monetary water accounts for each country, the authors provide an extensive discussion of water valuation as well as addressing a number of issues of regional importance, including water accounting for an international river basin and the impact of trade on each country s water use. By demonstrating the usefulness of water resource accounts, this book makes a major contribution to the literature on water economics and management, sustainable development, and to the development of environmental accounting in general. The Economics of Water Management in Southern Africa will appeal to a wide readership including: environmental and development economists NGOs concerned with sustainable development environmental advocacy groups professionals (economists and environmentalists) working in Africa on water and sustainable development issues water professionals national accounts experts and statisticians.

This book was released on 2020-10-26 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Niger River Basin is a transboundary basin covering nine riparian countries to the Niger River that are increasingly putting pressure on the available water resources as their populations expand. Yet, the nine countries are also among the poorest in the world and adequate exploitation of the water of the basin could be part of a broader strategy for poverty reduction in these countries. Major challenges to that end are the lacking water infrastructure and growing vulnerability to extreme weather hazards as the climate changes. In that context, a better understanding of the state of water resources in the basin is a crucial departure point for any measures towards the sustainable use of water. The Water Accounting Plus (WA+) system designed by IHE Delft with its partners FAO and IWMI has been applied to gain full insights into the state of the water resources in the basin.
