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.

Book Synopsis Agricultural Drainage Water Management in Arid and Semi-arid Areas by : Kenneth K. Tanji
Download or read book Agricultural Drainage Water Management in Arid and Semi-arid Areas written by Kenneth K. Tanji and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2002 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication contains guidelines to sustain irrigated agriculture and protect water resources from the negative impacts of agricultural drainage water disposal. Using case studies from Central Asia, Egypt, India, Pakistan and the US, this study highlights four broad groups of drainage water management options and provides information to enable assessment of their impact and contribution towards development goals and to facilitate the preparation of drainage water management plans and designs. The options are: water conservation, drainage water re-use, drainage water disposal and drainage water treatment. The full texts of the case studies can be found on the attached CD-ROM.

Book Synopsis Water Productivity in Agriculture by : J. W. Kijne
Download or read book Water Productivity in Agriculture written by J. W. Kijne and published by CABI. This book was released on 2003 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: *First title in a major new series *Addresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental security *Draws from scientists having a multitude of disciplines to approach this important problem In a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.
Book Synopsis Allocative inefficiency and farm-level constraints in irrigated agriculture in Pakistan by : Sanval Nasim
Download or read book Allocative inefficiency and farm-level constraints in irrigated agriculture in Pakistan written by Sanval Nasim and published by Intl Food Policy Res Inst. This book was released on with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we estimate the allocative inefficiency of groundwater in Pakistani agriculture and compare it across a set of farm-level constraints, using a panel dataset of rural households. The farm-level constraints include tenure, farm size, access to surface water and location on a watercourse. We use a stochastic approach, based on a system of equations to estimate both the technical efficiency of farms and the allocative efficiency of groundwater use. The allocation of surface irrigation water in Pakistan is fixed per unit of land, so its allocative inefficiency cannot be estimate. Therefore, we will treat surface water as a fixed factor and focus mainly on groundwater. The analysis sheds light on the utilization of irrigation water across a set of farm-specific characteristics. It also provides a basis for a psssible redesign of water policy. The results in this paper constitute the empirical basis for policy work that we will focus on in our future work.
Book Synopsis Soil Quality and Agricultural Sustainability by : R. Lal
Download or read book Soil Quality and Agricultural Sustainability written by R. Lal and published by CRC Press. This book was released on 1998-11-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation causes a shrinking of arable land resources, and the persistence of starvation and malnutrition. The depletion is compounded by the increasing populations of developing tropical nations, and the conversion of agricultural land to other uses. As a result, per capita grain harvesting and irrigated land is in steady decline all over the world. The decrease in horticultural resources and productivity has inspired Soil Quality and Agricultural Sustainability, which is based primarily on papers presented at the 1996 conference on soil degradation, sponsored by Ohio State University, the USAID and the International Agricultural Research Centers. The book addresses itself to six concerns: basic concepts and global issues, nutrient and water inputs, soil quality management in Asia, in Africa, and in the Tropical Americas, and future priorities. The Editor's goal is a new paradigm in soil quality research: a multidisciplinary approach. He proposes that an erosion management program include soil scientists, hydrologists, climatologists, sedimentologists, geographers, agronomists, agricultural engineers, land use planners, economists, anthropologists and social scientists. Lal advocates an optimistic, forward-thinking brand of soil science that concentrates on conservation and fertility. The 26 chapters explore what Lal considers to be the priorities: agricultural sustainability, soil quality, food security, quality restoration, long-term management, and the failure to adopt new technology. In sum, they paint a comprehensive portrait of the current state, and future prospects, for worldwide agronomic viability.
Book Synopsis Optimal groundwater management in Pakistan’s Indus Water Basin by : Nasim Sanval
Download or read book Optimal groundwater management in Pakistan’s Indus Water Basin written by Nasim Sanval and published by Intl Food Policy Res Inst. This book was released on 2016-01-15 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report we examine the management of groundwater in Pakistan’s Indus Basin through a model of groundwater extraction with hydrologic, economic, and tenure constraints. We develop a groundwater extraction model for the Indus Basin and simulate the effect of common property management (the status quo in the Indus Basin) and optimal management on groundwater extractions, water table height, groundwater quality, and annual net benefits from irrigated agriculture. The analysis provides a framework to develop and discuss policies that could lead to the optimal management of groundwater.
