Book Description
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.

Book Description
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 Description
Agricultural water management is a vital practice in ensuring reduction, and environmental protection. After decades of successfully expanding irrigation and improving productivity, farmers and managers face an emerging crisis in the form of poorly performing irrigation schemes, slow modernization, declining investment, constrained water availability, and environmental degradation. More and better investments in agricultural water are needed. In response, the World Bank, in conjunction with many partner agencies, has compiled a selection of good experiences that can guide practitioners in the design of quality investments in agricultural water. The messages of 'Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management' center around the key challenges to agricultural water management, specifically: - Building policies and incentives - Designing institutional reforms - Investing in irrigation systems improvement and modernization - Investing in groundwater irrigation - Investing in drainage and water quality management - Investing in water management in rainfed agriculture - Investing in agricultural water management in multipurpose operations - Coping with extreme climatic conditions - Assessing the social, economic, and environmental impacts of agricultural water investments 'Shaping the Future of Water for Agriculture' is an important resource for those interested and engaged in development with a focus on agricultural water.

Book Description
This book presents the first comprehensive assessment of water resources in Pakistan including surface water resources and groundwater resources. It gives a detailed overview of issues and challenges related to water which have not been adequately addressed e.g. water resource vulnerability to climate change, groundwater depletion and contamination, and water governance etc. It includes a collection and compilation of unpublished and scattered data from the archives and repositories of various national institutions and organization. Given the literature dearth, this book will not only be a comprehensive assessment of water resources in Pakistan but can also can as outstanding textbook on water resource management in Pakistan. It will attract a great range of readership including water specialists, researchers, undergraduate and post graduate students and policy makers from Pakistan as well as from overseas.

Book Description
This working paper presents the results of a comprehensive groundwater survey of Pakistan, designed to understand the dynamics of groundwater use, operation and maintenance patterns, socio-economics of groundwater irrigation, land use pattern, crops, yields, and groundwater irrigation practices. For this survey, Pakistan was divided into 83 nodal intervals, with each node covering an area of 100 km*100 km; and one village from center of each grid was selected as sample. From each sample village, 15 tubewell owners were randomly selected as respondents. In total, 1200 private tubewell owners were interviewed for this study. The distance between two sample villages was kept more than 40 kilometers. This was done to avoid influences of one-village activities on the other.

Book Description
This publication examines issues of water sector reform and performance from the perspectives of institutional economics and political economic studies. The authors develop an alternative quantitative assessment methodology based on the principle of 'institutional ecology', as well as data collected from 127 water experts from 43 countries and regions around the world using a cross-country review of recent water sector reforms within an institutional transaction cost framework.

Book Description
Evidence from Pakistan's Punjab indicates that monopoly power in the market for groundwater (irrigation water extracted using private tubewells) results in a substantial resource misallocation. But despite this substantial misallocation of groundwater, a welfare analysis shows that monopoly pricing of groundwater has limited effects on equity and efficiency. Policies aimed at eliminating monopoly pricing would do little to help the poorest farmers.
