The perennial presence of plastic waste in the Indus River and its tributaries is a recent addition to the already extensive list of threats to water quality, ecological health, and environmental sustainability in Pakistan. While there is some information available, although insufficient, both on surface water resources as well as …
The perennial presence of plastic waste in the Indus River and its tributaries is a recent addition to the already extensive list of threats to water quality, ecological health, and environmental sustainability in Pakistan. While there is some information available, although insufficient, both on surface water resources as well as …
Groundwater is arguably the most poorly understood water resource in Pakistan a country in which matters of water resources are hotly debated on a regular basis. Groundwater has the potential to be the most reliable water resource for Pakistan, providing a buffer against the unpredictability of climate change and the …
Competition over limited water resources is one of the main concerns for the coming decades. Although water issues alone have not been the sole trigger for warfare in the past, tensions over freshwater management and use represent one of the main concerns in political relations between riparian states and may …
Hydropower is a valuable renewable energy resource in India, which can help in climate change mitigation and meet the increasing energy demands. However, the crucial role of climate change on hydropower production in India remains unexplored. Here using the observations and model simulations, we show that seven large hydropower projects …
The 1960 Indus Waters Treaty dividing the rivers of the Indus system between India and Pakistan has continued to function through two wars and numerous political tensions. Nevertheless, given mounting pressures on the Indus’ waters due to population growth, climate change and mismanagement, many call for abandonment or renegotiation of …
This paper presents future climate and runoff projections for the South Asia region under the RCP8.5 scenario with climate change informed by 42 CMIP5 GCMs. Runoff is projected for 0.5° grids using hydrological models with future climate inputs obtained by empirically scaling the historical climate series.

Surface irrigation is a common pool resource characterized by asymmetric appropriation opportunities across upstream and downstream water users. Large canal systems are also predominantly managed by the state. This paper studies water allocation under an irrigation bureaucracy subject to corruption and rent-seeking. Data on the landholdings and political influence of …
This report provides comprehensive information about the glacial lakes of five major river basins of the Hindu Kush Himalaya (HKH) — Amu Darya, Indus, Ganges, Brahmaputra, and Irrawaddy, including Mansarovar Interior Basin — representing the year 2005, which helps to fill the data gap of glacial lakes information in the …
Concern has been growing in recent years regarding the potential impact of climate change on Pakistan’s already stressed water resources. Rising temperatures, increasing saltwater intrusion in coastal areas, a growing threat of glacier lake outburst floods, more intense rainfall, and changes in monsoon and winter rainfall patterns are just some …
The objective of this study is to analyze heterogeneous perceptions of the relative importance of riverine ecosystem services to inform policy decisions. To improve allocation of scarce resources across competing uses, it is crucial to understand the values placed on various water uses. Based on electronic surveys conducted across three …
A likely consequence of global warming will be the redistribution of Earth’s rain belts, affecting water availability for many of Earth’s inhabitants. We consider three ways in which planetary warming might influence the global distribution of precipitation. The first possibility is that rainfall in the tropics will increase and that …
The nature and timing of rice domestication and the development of rice cultivation in South Asia is much debated. In northern South Asia there is presently a significant gap (c.4200 years) between earliest evidence for the exploitation of wild rice (Lahuradewa c.6000 BCE) and earliest dated evidence for the utilisation …
Groundwater abstraction from the transboundary Indo-Gangetic Basin comprises 25% of global groundwater withdrawals, sustaining agricultural productivity in Pakistan, India, Nepal and Bangladesh. Recent interpretations of satellite gravity data indicate that current abstraction is unsustainable, yet these large-scale interpretations lack the spatio-temporal resolution required to govern groundwater effectively. Here we report …
Freshwater scarcity is increasingly perceived as a global systemic risk. Previous global water scarcity assessments, measuring water scarcity annually, have underestimated experienced water scarcity by failing to capture the seasonal fluctuations in water consumption and availability. We assess blue water scarcity globally at a high spatial resolution on a monthly …
Runoff from snowmelt is regarded as a vital water source for people and ecosystems throughout the Northern Hemisphere (NH). Numerous studies point to the threat global warming poses to the timing and magnitude of snow accumulation and melt. But analyses focused on snow supply do not show where changes to …
Groundwater is an increasingly important water supply source globally. Understanding the amount of groundwater used versus the volume available is crucial to evaluate future water availability. We present a groundwater stress assessment to quantify the relationship between groundwater use and availability in the world's 37 largest aquifer systems. We quantify …
Estimation of extremely high rainfall (point or areal) is one of the major components of design storm derivation. The estimation of Probable Maximum Precipitation (PMP) involves selection of heavy rainstorms and its maximization for the moisture content during the rainstorm period. These heavy rainstorms are nothing but the widespread heavy …
Many irrigation systems are special cases of common-pool resources (CPRs) in which some users have preferential access to the resource, which in theory aggravates collective action challenges such as the under-provision of necessary infrastructure as a result of unequal appropriation of water resources. We present experimental evidence based on an …
Conventional energy resources are fast depleting and therefore alternative resources are required to sustain the fast progress and development of any nation. This situation is more pertinent to India where fast growing population and developmental activities are posing major challenges to the government as the country has limited resources of …
Global agricultural production is heavily sustained by irrigation, but irrigation system efficiencies are often surprisingly low. However, our knowledge of irrigation efficiencies is mostly confined to rough indicative estimates for countries or regions that do not account for spatio-temporal heterogeneity due to climate and other biophysical dependencies. To allow for …
