Abstract Over the past two decades, scholars have invoked E. P. Thompson's and James Scott's concept of a “moral economy” to explain how people mobilize notions of justice to make claims to water. We draw together 20 years of literature to assess the state‐of‐the‐art present in research on moral economies for water. We trace the historical foundations of the moral economies concept and its relevance to water; define the three basic components of a moral economy for water—(1) shared understandings of justice, (2) normative economic practices, (3) social pressure mechanisms—and provide examples of how they manifest globally. We then discuss how moral economies for water can cycle through four basic states—balanced struggle, intensified reaction, mass revolt, and collapse and dissolution—at different scales. We also explore the implications of the moral economies framework for key areas of current research on water: water sharing, water commons, water markets, and biocultural outcomes, and discuss the ways in which the moral economies framework dovetails with recent advances in water research, especially the economics of water and development. We argue that the moral economies framework is a powerful explanatory tool for understanding the relationships between ideas of water justice, economic behaviors, and mechanisms of social enforcement that complements other methodological approaches and theoretical perspectives. We envision moral economies for water as a field that can facilitate a range of norm‐based analyses of economic behavior and water justice, including across scales—from local to global—and in broad, integrative, multiscalar, and cross‐disciplinary ways.

Ice-binding site of surface-bound type III antifreeze protein partially decoupled from water
Combined SFG/MD analysis together with spectral calculations revealed that type III antifreeze proteins adsorbed at the air–water interface maintains a native state and adopts an orientation that leads to a partial decoupling of its ice-binding site from water.

Abstract Centralized water infrastructure has, over the last century, brought safe and reliable drinking water to much of the world. But climate change, combined with aging and underfunded infrastructure, is increasingly testing the limits of—and reversing gains made by—this approach. To address these growing strains and gaps, we must assess and advance alternatives to centralized water provision and sanitation. The water literature is rife with examples of systems that are neither centralized nor networked, yet meet water needs of local communities in important ways, including: informal and hybrid water systems, decentralized water provision, community‐based water management, small drinking water systems, point‐of‐use treatment, small‐scale water vendors, and packaged water. Our work builds on these literatures by proposing a convergence approach that can integrate and explore the benefits and challenges of modular, adaptive, and decentralized (“MAD”) water provision and sanitation, often foregrounding important advances in engineering technology. We further provide frameworks to evaluate justice, economic feasibility, governance, human health, and environmental sustainability as key parameters of MAD water system performance.

Abstract Water is an essential and often limiting resource that pervades all aspects of animal ecology. Yet, water economics are grossly understudied relative to foraging and predation, leaving ecologists ill‐equipped to predict how the intensifying disruption of hydrological regimes worldwide will impact communities. For savanna herbivores, reliance on surface water can increase exposure to predators and competitors, and thus strategies that reduce the need to drink are advantageous. Yet, the extent to which increasing dietary water intake while decreasing water loss enables animals to forego drinking remains unknown.We studied water budgets of sympatric African savanna antelopes that differ in size, bushbuck (Tragelaphus sylvaticus, ~35 kg) and kudu (T. strepsiceros, ~140 kg). We hypothesized that both species compensate for seasonally declining water availability by increasing consumption of moisture‐rich plants and reducing faecal water loss, and that these adjustments are sufficient for small‐bodied—but not large‐bodied—herbivores to avoid spending more time near permanent water sources as the dry season advances. We tested our predictions using temporally explicit data on antelope movements, diets, plant traits and drinking behaviour in Gorongosa National Park, Mozambique.Water content declined between the early and late dry seasons in roughly half of plant taxa consumed by antelope. Although both species reduced faecal water loss and shifted their diets towards relatively moisture‐rich plants as the dry season progressed, dietary water intake still declined. Contrary to expectation, kudu reduced selection for surface water in the late dry season without adjusting total time spent drinking, whereas bushbuck increased selection for surface water.We developed a generalizable approach for parsing the importance of dietary and surface water for large herbivores. Our results underscore that variation in surface‐water dependence is a key organizing force in herbivore communities, that simple allometric predictions about the behavioural and ecological consequences of this variation are unreliable. Understanding wildlife water economics is a research frontier that will be essential for predicting changes in species distribution and community composition as temperatures rise and droughts intensify.more » « less

Abstract Informed by decades of literature, water interventions increasingly deploy “gender‐sensitive” or even “gender transformative” approaches that seek to redress the disproportionate harms women face from water insecurity. These efforts recognize the role of gendered social norms and unequal power relations but often focus narrowly on the differences and dynamics between cisgender (cis) men and women. This approach renders less visible the ways that living with water insecurity can differentially affect all individuals through the dynamics of gender, sexuality, and linked intersecting identities. Here, we first share a conceptual toolkit that explains gender as fluid, negotiated, and diverse beyond the cis‐binary. Using this as a starting point, we then review what is known and can be theorized from current literature, identifying limited observations from water‐insecure communities to identify examples of contexts where gendered mechanisms (such as social norms) differentiate experiences of water insecurity, such as elevating risks of social stigma, physical harm, or psychological distress. We then apply this approach to consider expanded ways to include transgender, non‐binary, and gender and sexual diversity to deepen, nuance and expand key thematics and approaches for water insecurity research. Reconceptualizing gender in these ways widens theoretical possibilities, changes how we collect data, and imagines new possibilities for effective and just water interventions.

Abstract Energy transitions are reshaping hydrosocial relations. How they will be reshaped, however, depends on location and water's material relationship to other resources and industrial activities embedded within energy transitions. To highlight this, we focus on three different resources—coal, natural gas, and lithium—to signal how the water–energy nexus will be reworked in a transition away from fossil fuels. We examine the water–coal nexus as an example of a resource relationship that is transitioningout, or that is being moved away from in the green energy transition. Natural gas represents the “bridge fuel” usedthroughthe transition. Lithium illustrates a resourceinsidethe green transition, as it is a fundamental material for green technologiesinthe transition to a low‐carbon future. Coal, natural gas, and lithium each have their own material impacts to water resources that stem from their industrial lifecycle and different implications for communities shaped by coal, natural gas, and lithium activities. To explore this, we review each of these resources' connection to water, their legal and regulatory dimensions, and their impact on communities and water justice. We argue that the energy transition is also a hydrosocial transition that will create uneven water‐related benefits and burdens. To maximize sustainability and equity, efforts to decarbonize energy systems must examine the localized, place‐based hydrosocial relations that differentially affect communities.
