Book Synopsis Managing Basin Interdependencies in a Heterogeneous, Highly Utilized and Data Scarce River Basin in Semi-Arid Africa by : Jeremiah Kipkulei Kiptala
Download or read book Managing Basin Interdependencies in a Heterogeneous, Highly Utilized and Data Scarce River Basin in Semi-Arid Africa written by Jeremiah Kipkulei Kiptala and published by CRC Press. This book was released on 2020-04-30 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.
Book Synopsis Integrated Basin Modeling by : G. W. Kite
Download or read book Integrated Basin Modeling written by G. W. Kite and published by IWMI. This book was released on 2000 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: River basins are complex areas, combining the natural processes of precipitation, evapotranspiration, surface water and groundwater runoff with man-made features such as dams and reservoirs, diversions and irrigation schemes, and industrial and urban water uses. Computer models may be constructed to represent these natural and man-made processes. Such models are used to help understand processes that are difficult to measure (such as evaporation) and to study the effects of changes in land cover, water management or climate on the natural and man-made processes.
Book Synopsis Productivity and Performance of Irrigated Wheat Farms Across Canal Commands in the Lower Indus Basin by : Intizar Hussain
Download or read book Productivity and Performance of Irrigated Wheat Farms Across Canal Commands in the Lower Indus Basin written by Intizar Hussain and published by IWMI. This book was released on 2000 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the enormous differences in agricultural productivity that exist across farms and regions in Pakistan, where, for example, recent farm-level data from Sindh, indicates that irrigated wheat output per hectare varies from 0.5 to 5.4 tons across farms. Looks at the central goal of agricultural policy in the country, viz. improving and sustaining productivity, narrowing the existing productivity gaps, and enhancing resource use efficiencies to meet food requirements of a rapidly growing population.
Book Synopsis More Crop Per Drop by : Meredith Giordano
Download or read book More Crop Per Drop written by Meredith Giordano and published by IWA Publishing. This book was released on 2007-01-01 with total page 289 pages. 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.

Book Synopsis Urban-wastewater Reuse for Crop Production in the Water-short Guanajuato River Basin, Mexico by : Christopher Anand Scott
Download or read book Urban-wastewater Reuse for Crop Production in the Water-short Guanajuato River Basin, Mexico written by Christopher Anand Scott and published by IWMI. This book was released on 2000 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide. It also evaluates several alternative water-management scenarios through application of the Interactive River Aquifer Simulation (IRAS) model, developed by Cornell University and Resource Planning Associates.
Book Synopsis Farmer-based Financing of Operations in the Niger Valley Irrigation Schemes by : Charles L. Abernethy
Download or read book Farmer-based Financing of Operations in the Niger Valley Irrigation Schemes written by Charles L. Abernethy and published by IWMI. This book was released on 2000 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report deals with some experiences of a set of irrigation systems situated in the Republic of Niger, along both banks of the Niger River. All these systems draw water from the river through low-lift, electrically powered pumping stations, which have been installed by the Government of Niger over the past 30 years. Irrigation of this kind is not a tradition in Niger. The introduction of this technology caused considerable changes in the way of life of local communities.

Book Synopsis Using Datasets from the Internet for Hydrological Modeling by : Martin Lacroix
Download or read book Using Datasets from the Internet for Hydrological Modeling written by Martin Lacroix and published by IWMI. This book was released on 2000 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public domain datasets are freely available on the Internet are easy to obtain, and often more up-to-date than those from local sources. This simplifies the modeling process and increases the ability to model basins anywhere in the world, from anywhere with Internet access. Although not all types of data are available, and some conversions may be needed, the information provided does allow for quick and easy simulations of basins. The Semi-Distributed Land-Use Runoff Process (SLURP) hydrological model has been designed to take advantage of such data sources. The application described in this report uses public domain data for topography, land use, seasonal variation in leaf area index (for transpiration) and climate data- all without calibration of parameters.
