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 Estimating Productivity of Water at Different Spatial Scales Using Simulation Modeling by : Peter Droogers
Download or read book Estimating Productivity of Water at Different Spatial Scales Using Simulation Modeling written by Peter Droogers and published by IWMI. This book was released on 2001 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: A clear understanding of the current water balance is required to explore options for water saving measures. However, measurement of all the terms in the water balance is infeasible in terms of spatial and temporal scale, but hydrological simulation models can fill the gap between measured and required data. For a basin in Western Turkey, simulation modeling at three different scales, field, irrigation scheme and basin scale, was performed to obtain all terms of the water balance. These water balance numbers were used to calculate the Productivity of Water at the three spatial levels distinguished to assess the performance of the systems.

Book Synopsis The Indus Basin of Pakistan by : Winston H. Yu
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.
Book Synopsis Predicting Water Availability in Irrigation Tank Cascade Systems by : C. J. Jayatilaka
Download or read book Predicting Water Availability in Irrigation Tank Cascade Systems written by C. J. Jayatilaka and published by IWMI. This book was released on 2001 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Better water management in irrigation tank cascade systems is vital in achieving higher productive use of available water. To develop and implement management practices aimed at improving effective use of water, studies leading to the development of models that can predict available tank water in irrigation tank cascade systems are invaluable. This report presents a simple water balance model, Cascade, developed to predict tank water availability in the Thirappane tank cascade system in Anuradhapura, Sri Lanka. The report includes calibration of the model and its application to predict tank water availability for rice crops over a 10-year period.
Book Synopsis Alternate Wet/dry Irrigation in Rice Cultivation by : Wim van der Hoek
Download or read book Alternate Wet/dry Irrigation in Rice Cultivation written by Wim van der Hoek and published by IWMI. This book was released on 2001 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: More irrigated land is devoted to rice than to any other crop. A method to save water in irrigated rice cultivation is the intermittent drying of the rice fields, known as alternate wet/dry irrigation (AWDI). This report reviews previous studies in AWDI, with a focus on mosquito vector control, water saving, and rice yields. Examples are provided from a number of countries.
Book Synopsis Valuing Water in Irrigated Agriculture and Reservoir Fisheries by : Mary E. Renwick
Download or read book Valuing Water in Irrigated Agriculture and Reservoir Fisheries written by Mary E. Renwick and published by IWMI. This book was released on 2001 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although irrigation projects often provide water for more than crop irrigation, water allocation and management decisions often do not account for nonirrigation uses of water. Failure to account for the multiple uses of irrigation water may result in inefficient and inequitable water allocation decisions. Decision-makers often lack information on the relative economic contributions of water in irrigation and nonirrigation uses. This report addresses this problem. It examines the relative economic contributions of irrigated agriculture and reservoir fisheries in the Kirindi Oya irrigation system, located in Southeastern Sri Lanka. The results of the analysis indicate the importance of both irrigated paddy production and reservoir fisheries to the local economy. They also demonstrate significant potential financial and economic gains to irrigated agriculture from improvements in water management practices. Since these water uses are interdependent, policy makers must consider how changes in water management practices may affect reservoir levels and water quality and the fisheries that depend on them.
Book Synopsis Small Irrigation Tanks as a Source of Malaria Mosquito Vectors by : Felix P. Amerasinghe
Download or read book Small Irrigation Tanks as a Source of Malaria Mosquito Vectors written by Felix P. Amerasinghe and published by IWMI. This book was released on 2001 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thousands of small irrigation reservoirs (tanks) exist in rice ecosystems in malarious regions of south Asia. The potential of these tanks to generate malaria-transmitting mosquitoes has not been adequately evaluated. Through a study of nine small irrigation tanks in north-central Sri Lanka, this report provides an assessment of the capacity of tanks to generate malaria and nuisance mosquitoes, factors that contribute to mosquito generation, and measures that could ameliorate the problem.
Book Synopsis Improving agricultural productivity for poverty alleviation through integrated service provision with public-private sector partnerships: Examples and issues by : Hussain, Intizar
Download or read book Improving agricultural productivity for poverty alleviation through integrated service provision with public-private sector partnerships: Examples and issues written by Hussain, Intizar and published by IWMI. This book was released on 2004 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enduring low agricultural productivity is one of the major causes of rural poverty in South Asia. Based on a review of recent empirical studies, this paper focuses on three key questions: (1) why is agricultural productivity low in the region?; (2) what are the key constraints and opportunities for enhancing agricultural productivity; and (3) what are the effective mechanisms to improve access to key productivity enhancing technologies, factors and services. Two major points raised in the paper are: (a) improved management of land and water is important for increasing productivity, but equally important is farmer access to non land and water-related inputs and services, which through their complementary relationships with water, increase the productivity and value of water. Even if most of the constraints related to land and water are removed through improved management, the resulting gains in productivity may not be sufficient-in the presence of constraints related to other factors and services-to have any significant impacts on poverty. Therefore, in order to generate any major increases in productivity, improved access for farmers to non land and water-related factors and services is also important; (b) access to these factors and services can be improved by providing them in an integrated manner with public-private sector partnerships. Based on examples of various models, initiatives and practices from Pakistan, India, Sri Lanka, China, Sub-Saharan Africa and other countries, the study suggests a framework for integrated services provision in the agriculture sector, and raises key research issues and questions to be explored.
Book Synopsis Wells and Welfare in the Ganga Basin by : Tushaar Shah
Download or read book Wells and Welfare in the Ganga Basin written by Tushaar Shah and published by IWMI. This book was released on 2001 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report analyzes the history of groundwater development in the eastern Uttar Pradesh region over the 1950-1990 period. Its main conclusion is that the story of groundwater-based livelihood creation in the Ganga basin is one of failed public initiatives and successful adaptive responses by private agents. However, tube-well-induced agrarian dynamism in eastern Uttar Pradesh and north Bihar in recent years can spread to the entire basin if public policy makers learn correct lessons from the experience of these two subregions.
Book Synopsis Hydronomic Zones for Developing Basin Water Conservation Strategies by : D. J. Molden
Download or read book Hydronomic Zones for Developing Basin Water Conservation Strategies written by D. J. Molden and published by IWMI. This book was released on 2001 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, the concept and procedures of hydronomic (hydro water + nomus management) zones are introduced. A set of six hydronomic zones are developed and defined based on key differences between reaches or areas of river basins. These are the: Water Source Zone, Natural Recapture Zone, Regulated Recapture Zone, Stagnation Zone, Final Use Zone, and Environmentally Sensitive Zone. The zones are defined based on similar hydrological, geological and topographical conditions and the fate of water outflow from the zone. In addition, two conditions are defined which influence how water is managed: whether or not there is appreciable salinity or pollution loading; and whether or not groundwater that can be used for utilization or storage is present. Generic strategies for irrigation for four water management areas, the Natural Recapture, Regulated Recapture, Final Use, and Stagnation Zones, are presented. The Water Source Zone and Environmentally Sensitive Zone are discussed in terms of their overall significance in basin water use and management.
