Water allocations for canal commands are not uniform throughout Pakistan. They vary from 2.5 to 15 cusec (ft3/sec) per 1,000 acres (i.e. 0.18 – 1.1 litre/sec/hectare) for different canal commands. This variability in water allowance (WA) has resulted in low water productivity (kg of yield per m3 of water use), an indicator used to assess efficient water use, especially in command areas having higher water allocations. In this study, satellite imagery was used to estimate crop water use and corresponding water productivity for each canal command area of the Indus Basin Irriga-tion System. Three years were selected for the study and two representative canal commands (Lower Chenab and Muzaffargarh Canal) were selected for detailed analysis and ground truthing. Spatially distributed maps of land use, crop water use, groundwater use and quality, soil and water salinity, and crop yields at a pixel resolution of 250 m (6.25 ha) were prepared and then verified by field surveys. GIS maps of canal water availability/supply were also prepared to account for the volume of water supplied through irrigation. This spatial database was used to evaluate and create maps of water productivity in the different canal commands.

Climate Change and Plants: Biodiversity, Growth and Interactions Evidence is raised daily of the varying climate and its impression on both plants and animals. Climatic changes influence all agriculture factors, which can potentially adversely affect their productivity. Plant activities are intimately associated with climate and concentration of atmospheric carbon dioxide. Climate Change and Plants: Biodiversity, Growth and Interactions examines how plant growth characters influence and is influenced by climate change both in past and present scenarios. This book covers cutting-edge research of key determinants of plant growth in response to atmospheric CO2 enhancement and global warming. Features Discourses numerous areas of sustainable development goals projected by the UN as part of the 2030 agenda Highlights appropriate approaches for maintaining better plant growth under changing climatic conditions Presents diversity of techniques used across plant science Is designed to cater to the needs of researchers, technologists, policymakers and undergraduate and postgraduate students studying sustainable crop production and protection Addresses plant responses to atmospheric CO2 increases

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.

The Indus and Ganges River Basin, being the most populous in the world, is under extreme pressure to sustain food security. Production resources including water are being exploited to various levels from underdevelopment to heavy overexploitation. This report provides a bird’s eye view of the basin and focuses on the nexus between agricultural production and water consumption, making it possible to pinpoint the areas with high/low water productivity and identify the factors behind this, which helps to promote informed decision making in light of environmental sustainability.

This book provides an overview of facts, theories and methods from hydrology, geology, geophysics, law, ethics, economics, ecology, engineering, sociology, diplomacy and many other disciplines with relevance for concepts and practice of water resources management. It provides comprehensive, but also critical reading material for all communities involved in the ongoing water discourses and debates. The book refers to case studies in the form of boxes, sections, or as entire chapters. They illustrate success stories, but also lessons to be remembered, to avoid repeating the same mistakes. Based on consolidated state-of-the-art knowledge, it has been conceived and written to attract a multidisciplinary audience. The aim of this handbook is to facilitate understanding between the participants of the international water discourse and multi-level decision making processes. Knowing more about water, but also about concepts, methods and aspirations of different professional, disciplinary communities and stakeholders professionalizes the debate and enhances the decision making.

This working paper takes stock of Pakistan's water resource availability, delineating water supply system and its sources including precipitation and river flows, and the impact of increasing climatic variability on the water supply system. In particular, the paper focuses on the current water usage and requirements in the agricultural sector, and how changing climatic conditions will affect the consumption patterns. With inflows expected to become more variable in the coming years, the severity of climatic extremities will become more pronounced, driving up water demands in addition to the demand increase from a rising population and urbanization. Over extraction of groundwater resources is also disturbing the water calculus and pushing the country towards a critical demand-supply gap.

This book focusses on hydrological modeling, water management, and water governance. It covers the applications of remote sensing and GIS tools and techniques for land use and land cover classifications, estimation of precipitation, evaluation of morphological changes, and monitoring of soil moisture variability. Moreover, remote sensing and GIS techniques have been applied for crop mapping to assess cropping patterns, computation of reference crop evapotranspiration, and crop coefficient. Hydrological modeling studies have been carried out to address various issues in the water sector. MODFLOW model was successfully applied for groundwater modeling and groundwater recharge estimation. Runoff modeling has been carried out to simulate the snowmelt runoff together with the rainfall and sub-surface flow contributions for snow-fed basins. A study has been included, which predicts the impact of the land use and land cover on stream flow. Various problems in the water sector have been addressed employing hydrological models such as SWAT, ArcSWAT, and VIC. An experimental study has been presented wherein the laboratory performance of rainfall simulator has been evaluated. Hydrological modeling studies involving modifications in the curve number methodology for simulation of floods and sediment load have also been presented. This book is useful for academicians, water practitioners, scientists, water managers, environmentalists, and administrators, NGOs, researchers, and students who are involved in water management with the focus on hydrological modeling, water management, and water governance.
