Book Description
Groundwater use has increased across Pakistan, nowhere more than in the large canal-irrigated areas of the Indus basin irrigation system (IBIS). These mega-irrigation systems use surface water and groundwater, often in equal measure. The two water sources are the same source and should be managed as such. Groundwater supplied by seepage from the surface system is pumped up to complement surface water supplies. The delivery of surface water supplies determines how much groundwater is used and how much recharge will happen. In most cases, such conjunctive management will not 'cost' extra water to make significant gains in yields and support drought resilience. This case study discusses Pakistan's contrasting experiences with conjunctive use in the Punjab and Sindh provinces and attempts to move toward conjunctive management.

Book Description
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 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 It includes a collection and compilation of unpublished and scattered data from the archives and repositories of various national institutions and organization.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
Pakistan is highly dependent on irrigated agriculture for employment, income generation and food security—around 90 percent of all food production relies on either surface or groundwater irrigation. The growing dependence of agriculture but also industries and the drinking water sector on groundwater has led to the overexploitation of groundwater resources and, in some areas, to the deterioration of groundwater quality. Fiscal incentives for solarization of irrigation/drinking water pumps are likely to further increase water withdrawals and make water governance more complex. To understand the perspectives of groundwater users, a qualitative study was conducted in the alluvial groundwater systems of Punjab as well as the hard rock systems of Balochistan. Interviews with key informants at federal, provincial, and district level were also conducted to capture insights from additional decisionmakers affecting groundwater management and governance. The study identified a series of challenges around groundwater management and use, including overexploitation of groundwater resources, worsening groundwater quality raising serious health challenges, lack of communities’ participation in decision making, particularly women, non-availability of actionable data, weak enforcement of laws and regulations relating to groundwater governance, and partisan decision-making driven by political influentials and local bureaucracies. Solarization of irrigation pumps without proper regulatory and monitoring framework is expected to exacerbate groundwater extraction and accelerate water stress. The study strongly suggests an urgent need for not only integrated water management at all levels with equitable distribution of water resources but also to engage local communities and other stakeholders, including women in water conservancy awareness campaigns, groundwater quality monitoring, and decision-making. Moreover, the management and governance of water, particularly groundwater, must be insulated from political and partisan decision making. It is equally important to look at the quality of groundwater from a wider prism, considering health and water supply, sanitation and hygiene to address the increase in water borne diseases.

Book Description
The water policy issues are well- documented in a large set of reports and studies, completed over time showing that the policy prescription and its implementation has been weak in the past as this book reveals. The key reforms initiated were lost due to a lack of government’s will and commitment and more so by pervasive political economy of water. Given this background, each chapter in the book follows a balanced approach in seeking and evaluating alternate solutions to water management issues, especially improvements in water governance and tackling new challenges emerging from the climate change in the short and long term. This approach underpins the importance of moving from the culture of piloting projects to actual implementation on an impact-oriented scale. The book would also highlight that most of the water solutions lie outside the water sector such as agriculture, population, economy, etc. Post COVID-19 policies are exploring new food-health nexus that calls for nature based solutions for our future agriculture growth. The book would show case pioneer work underway in Pakistan on how new policy discourse can reduce water use in agriculture without investing in expensive water technology and infrastructure, thus saving enough water for other competing purposes.

Book Description
These notes present the impressions gathered by a team of Indian and Pakistani economists on contemporary issues in irrigation management in these two countries. The authors suggest that the two countries can learn important lessons by comparing notes on several issues: [a] what would work best in ensuring equitable access to irrigation - physical rehabilitation being tried out in Pakistan Punjab with the help of the army under the military rule offers interesting possibilities in terms of scale and impact as does the Andhra Pradesh model of irrigation reform, [b] the experience in both countries so far defies the uncritically accepted premise that under farmer-management, irrigation systems will be more equitable, [c] why farmers in Pakistan Punjab have to use 16-20 horsepower (hp) diesel engines to pump groundwater from 25-40 feet while north Indian farmers have been doing the same with 5 hp engines--if it is because of compulsion of habit, appropriate policies can save Pakistan substantial diesel fuel per year, [d] India needs to ask why diesel engines in Lahore cost only 40-50 percent of the retail price they command in Lucknow or Ludhiana--we suggest allowing free imports of Chinese pumps will do away with the need for pump subsidies that keep diesel engines over-priced in India, [e] both Pakistan and India need to pay serious attention to promoting simple pump modifications that can increase fuel efficiency of their pumps by 40-70 percent, [f] India and Pakistan need to compare notes on their rich experience of electricity pricing policies to achieve viability of electricity supply to farmers and to achieve important goals of groundwater management and policy.

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.
