In recent years scholars have advanced our understanding of the biophysical, socioeconomic, and geopolitical impacts of dams and hydropower infrastructure around the globe. Databases and maps have emerged that allow global comparisons between countries and river basins. However, reliable and freely available data do not exist for many regions. As a result, data limitations and quality issues persist, which limit the quality of analyses based on these datasets. This is particularly true in regions where hydropower infrastructure development is proceeding most rapidly, including South Asia's Third Pole region. We identify and describe serious quantitative and qualitative data dilemmas of existing databases. We divide these into location, size, type, and status. At the most basic level, these dilemmas mean that incorrect location and, more importantly, massive underrepresentation of existing and future projects generates incorrect conclusions. That underrepresentation results largely from uncritically equating absence of data with absence of infrastructure. We also argue that project function should be more reliably recorded (for both dams and hydropower projects), that project status should be clear (many existing projects are still passed off as future), and that smaller projects should be systematically recorded (their cumulative importance is often underestimated). These four dilemmas all have important implications for analyses based on existing datasets. The World Index of Hydropower, Dams, and Reservoirs (WIHDR) described here represents a major advance on all four points. For the first time, 652 existing hydropower plants (277 large and 375 small), 162 under construction, and 720 planned hydropower plants have been georeferenced and systematically recorded for the Indus‐Ganga‐Brahmaputra region.

Legal geography seeks to understand the complex interactions between people, law, and space. It exists as an interdisciplinary endeavor, incorporating intellectual threads from critical legal studies, political geography, sociology, and related work. The purpose of this focus article is to introduce legal geography to water scholars as practical means to study law and space to human–water relationships (i.e., hydrosocial relations). We start by tracing a history of legal geography's development as a field and highlight important works in legal geography past and present. We then focus on ways legal geography has been utilized to explore four broad topics within the scope of human water: rights to water, water governance, water as imagined and represented, and value of water. We conclude that legal geography frameworks applied to water research may be useful for furthering the understanding of many of the issues important to WIRES Water readers.

Though safe drinking water for all is a global public health goal, disparities in access persist worldwide. We present a critical review of primary‐data based environmental justice (EJ) studies on drinking water. We examine their findings in relation to the broader EJ and drinking water literatures. Using pre‐specified protocols to screen 2423 records, we identified 33 studies for inclusion. We organized our results using the following questions: (1) what sampling and data collection methods are used; (2) how is (un)just access to water defined and measured; (3) what forms of environmental injustice are discussed; (4) how are affected communities resisting or coping; and (5) what, if any, mechanisms of redress are advocated? We find that while many studies analyze the causes and persistence of environmental injustices, most primary‐data studies on drinking water are cross‐sectional in design. Many such studies are motivated by health impacts but few measure drinking water exposures or associated health outcomes. We find that, while distinct types of injustice exist, multiple types are either co‐produced or exacerbate one another. Recognitional injustice is emerging as an undergirding injustice upon which others (distributional or procedural) can take hold. Tensions remain regarding the role of the state; redress for inequitable water access is often presumed to be the state's responsibility, but many EJ scholars argue that the state itself perpetuates inequitable conditions. The accountability for redress under different forms of water governance remains an important area for future research.

Reducing uncertainty in quantifying basin‐scale water‐budget components is one of the most vexing problems for water‐resource managers. Although a vast literature addresses methods and scales of component estimates, uncertainty associated with these estimates is often lacking. Here we review sources of uncertainty and compile reported uncertainty estimates for measurement and estimation methods for six water‐budget components: precipitation, streamflow, evapotranspiration, subsurface discharge, infiltration, and recharge. Quantifying the uncertainty in each water‐budget component data is required before total water‐budget uncertainty can be determined.

Wastewater‐based surveillance can be used as an early warning system to identify COVID‐19 outbreaks because the viral load can be observed in sewage before it is clinically verified. Wastewater surveillance of SARS‐CoV‐2 can trace the transmission dynamics of infection in communities when using the scale of a wastewater diversion and treatment system. Using this early detection method can help protect human health and mitigate socio‐economic losses. It can help quantify the epidemiological data of a given population in real‐time and circumvent the need for other epidemiological indicators. There are challenges in using this technique in areas with underdeveloped sewerage infrastructure. It is especially the case in developing nations where uniform protocols for viral detection are lacking, and wastewater is heterogeneous because of environmental and operational conditions. This article explains the need for and importance of wastewater‐based surveillance for SARS‐CoV‐2. It lays out the most recent methodological approaches for detecting SARS‐CoV‐2 in municipal wastewater and outlines the main challenges associated with wastewater‐based epidemiology (WBE). The article includes a case study of surveillance work across India to demonstrate how a developing nation manages research and locational challenges. The socio‐economic, ethical, and policy dimensions of WBE for SARS‐CoV‐2 are also discussed.

In this article, we introduce the “dwelling paradox” to explore how the state actively produces water insecurity for people experiencing homelessness in the Global North. We explain that the dwelling paradox is (1) produced by a modernist ideology of public service delivery that privileges water provision through private infrastructural connections in the home; (2) is reproduced by the welfare‐warfare state, which has increasingly weaponized public water facilities and criminalized body functions in public space; and (3) is actively contested by some houseless communities, who challenge hegemonic ideals of the “home”—and its water infrastructure—as a private, atomized space. In advancing a relational and spatial understanding of water insecurity, we use the dwelling paradox to illustrate how unhoused people are caught in a space of institutional entrapment that is forged by state power and amplified by anti‐homeless legislation. Such spaces of entrapment make it extremely difficult for unhoused people to achieve a safe, healthy, and thriving life—the basis of the human rights to water and sanitation.

This review explores the implications of climate change for the functioning of plant species as biogeomorphic engineers of temperate river systems, including the potential for an increasing role of invasive alien plant species (IAPS). First, we introduce engineer plants as important controls, along with flowing water and transported sediments, on the morphodynamics of river systems and the likelihood that climate change may affect the contributions of species within their native habitats. We then examine through the prism of the fluvial biogeomorphic succession model how climate change may accelerate the establishment of IAPS, the possible consequences for the performance and/or persistence of native engineer plant species, and thus the potential pathways of influence for IAPS on river morphodynamics. Finally, we present examples of the impacts of invasions by specific plant species along particular river systems and consider their potential biogeomorphic impact against a backdrop of climate change. Loss, replacement, or displacement of native plant species in the river corridor by IAPS can potentially alter biogeomorphic phenomena by directly increasing or decreasing erosion and/or sedimentation and the associated development of fluvial landforms. In the shorter term, increased climate disturbance may provide more establishment opportunities for opportunistic IAPS. In the longer term, under heavy establishment, IAPS may alter the coupled assembly of plant communities, fluvial landforms and ecosystem development, potentially resulting in river landscape metamorphosis and significantly changed habitat conditions.

Mine pit lakes are formed when open‐cut pits flood with water, and these lakes occur by the thousands on every inhabited continent. The remediation and closure of pit lakes is a pressing issue for sustainable development and provision of freshwater ecosystem services. While pit lakes can be spectacular examples of recreation and renewal, pit lakes may be better known for their poor water qualities and risks to communities and the environment. Often the public wants to simply “fill the pits in” to restore a terrestrial landscape, but this is not always possible. Therefore, planning for remediation and future uses is likely to provide the best outcome. Poor water quality is not necessarily a barrier to future use, although it may limit the number of uses. Short‐term future uses tend to require commercial viability, active infrastructure investment, and maintenance, and should transition to complementary long‐term uses that promote biodiversity. Long‐term future uses require relatively less ongoing maintenance beyond the initial investment and adhere to the principles that pit lakes should be safe, sustainable, and non‐polluting in perpetuity. Pit lakes will eventually develop “ecosystem values,” and the time to do so depends on the nature of the intervention and the values ascribed by the community. Where possible, closing pit lakes as sustainable ecosystems is the most realistic goal that permits a variety of future uses that is likely to see pit lakes valued by future generations.
