The bed of fluvial ecosystems plays a major role in global biogeochemical cycles. All fluvial sediments migrate and although responses of aquatic organisms to such movements have been recorded there is no theoretical framework on how the frequency of sediment movement affects streambed ecology and biogeochemistry. We here developed a theoretical framework describing how the moving‐resting frequencies of fine‐grained sediments constrain streambed communities across spatial scales. Specifically, we suggest that the most drastic impact on benthic and hyporheic communities will exist when ecological and biogeochemical processes are at the same temporal scale as the sediment moving‐resting frequency. Moreover, we propose that the simultaneous occurrence of streambed patches differing in morphodynamics should be considered as an important driver of metacommunity dynamics. We surmise that the frequency of patch transition will add new dimensions to the understanding of biogeochemical cycling and metacommunities from micro‐habitat to segment scales. This theoretical framework is important for fluvial ecosystems with frequent sediment movement, yet it could be applied to any other dynamic habitat.

Farmer‐led irrigation development (FLID) is a process where individual farmers play a driving role in configuring agricultural technology practices, crop‐specific market linkages, land and water governance arrangements, and informal and formal value chain actor networks. Multilateral donors are increasingly funding FLID as a development strategy in sub‐Saharan Africa to expand irrigation coverage, recognizing co‐benefits such as enhanced climate resilience, improved household food insecurity, and alleviated rural poverty. This review suggests that FLID can be understood as a farmer response to the shortcomings of neoliberal structural adjustment and cost recovery policies. Simultaneously, multilateral donor‐funded FLID projects advance Integrated Water Resource Management (IWRM) policy tools, exposing a policy paradox. Following multilateral and bilateral donor investments in FLID over 30 years, the review establishes how farmers initiated their own irrigation investments and the subsequent “scale‐up” of FLID by multilateral finance institutions. The stances of multilateral donors (e.g., World Bank) and multilateral entities (e.g., FAO) toward water governance for FLID present a contradictory picture. The review demonstrates how multilateral donors have transformed FLID into distinct agribusiness project models through Water‐Energy‐Food nexus and climate frameworks, with attention to farmers' collective action strategies. However, collective action as an avenue for the expansion of FLID does not automatically guarantee a socially inclusive and environmentally sustainable process across project models. Future research should focus on examining socioeconomic impacts on farmers participating in a project intervention, as well as farmers and irrigated value chain actors in proximal areas, to work toward effective and equitable water governance for FLID.

The legacy of the sub‐continent has led to a complex geopolitical rivalry in the Brahmaputra River Basin, shared by China, India, Bhutan, and Bangladesh. Each riparian state has a varying interest and development agenda, hindering the identification of common interests for water cooperation. This article presents the intertwining of regional geopolitics with the basin hydropolitics, restraining positive interaction, thus, leading to a status quo in the BRB. While maintaining a purposeful status quo seems to be a prudent move by the riparians, the local communities continue to suffer due to the impasse.

Flint, Michigan reignited the public discourse surrounding lead contamination in drinking water with Newark, New Jersey recently experiencing its own lead-in-water crisis. Following Flint's experience, the Environmental Protection Agency proposed changes to the Lead and Copper Rule (LCR), but these changes may not produce better detection of contamination. LCR testing requirements were evaluated for their ability to predict or identify problems from the recent (2015-2019) Newark lead exceedance data. LCR compliance and water quality data were obtained from the New Jersey Department of Environmental Protection (NJDEP) website. Between 2002 and 2015, Newark sampled on a reduced sampling plan (50 samples once every 3 years), as required, for lead and copper. These samples were divided between Newark's two water sources with uneven sampling distribution across the city, further limiting the potential to identify a risk of lead in drinking water. Results suggest a more rigorous testing requirement may have identified the problem sooner. Limitations related to the LCR that prevented Newark water suppliers from earlier detection of lead risk will continue under the revised LCR. This article is categorized under:Engineering Water > Water, Health, and SanitationScience of Water > Water Quality.

Pollution with trace elements is considered a global problem due to their persistence, nondegradability, and toxicity to living organisms. Aquatic ecosystems are often the final sinks for trace elements, but these pollutants are quickly diluted and difficult to detect and, therefore, comprehensive monitoring of pollution is needed to implement appropriate control measures and prevent irreversible damage to these habitats. Bioindication is one of the recommended methods as it provides information not only on the pollution level but also on the bioavailability of elements and their biological impact. The paper is a synthetic review of the knowledge about the use of macrophytes as passive bioindicators (accumulator taxa) of trace element pollution in aquatic ecosystems. Various aspects of bioindication using accumulator aquatic plants are discussed: the criteria defined for the organisms used in biogeochemical bioindication, advantages of plants as accumulative bioindicators, general trends in the uptake, and accumulation of pollutants by macrophytes (including differences between life forms, organs, and seasons). The use of various groups of macrophytes in accumulative bioindication is described in detail with an emphasis on the relationship between element levels in plant tissues and their habitat as well as performance in the detection of pollution gradients. Knowledge gaps and limitations in the field of bioindication using accumulative macrophytes are indicated and the future perspective is outlined.

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.

Salt pollution is a threat to freshwater ecosystems. Anthropogenic salt inputs increase lake and stream salinity, and consequently change aquatic ecosystem structure and function. Elevated salt concentrations impact species directly not only through osmoregulatory stress, but also through community‐level feedbacks that change the flow of energy and materials through food webs. Here, we discuss the implications of road salt pollution on freshwater rivers and lakes and how “one size fits all” ecotoxicity thresholds may not adequately protect aquatic organisms.

Contemporary management practices have artificially confined (strangled) river systems in Aotearoa New Zealand to support intensified land use in riparian areas. These practices work against nature, diminishing the functionality and biodiversity values of living rivers, and associated socio‐cultural relations with rivers. River confinement can accentuate flood risk by promoting development in vulnerable locations and limiting the flexibility to adapt to changing climate, prospectively accentuating future disasters. To date, uptake of space‐to‐move management interventions that seek to address such shortcomings is yet to happen in Aotearoa New Zealand. This is despite the fact that such practices directly align with Māori (indigenous) conceptualizations of rivers as indivisible, living entities. Treaty of Waitangi obligations that assert Māori rights alongside colonial rights of a settler society provide an additional driver for uptake of space‐to‐move initiatives. This article outlines a biophysical prioritization framework to support the development and roll out of space‐to‐move interventions in ways that work with the character, behavior, condition, and evolutionary trajectory (recovery potential) of each river system in Aotearoa.

Ecosystem metabolism is a vital measurement for understanding the dynamics of aquatic environments. China has a range of aquatic resources and in the past two decades, there has been an increasing interest in ecosystem metabolism research. However, no studies have evaluated overall variation and environmental patterns which affect metabolism in China's vast range of aquatic systems. For this paper, we searched for articles with metabolism data for China's major rivers and coastal zones from 2000 to 2020. We identified 127 studies documenting ecosystem metabolism functions including primary production (PP), community respiration (CR) and net ecosystem production (NEP). Using path analysis, we documented relationships across a range of environmental parameters. Light availability affected riverine and coastal PP (<0.1–10.7 gC m−2 day−1), while riverine PP was also linked to precipitation, photosynthesis‐related biomass, and land‐use variables. Riverine and coastal CR ranged from 0.01 to 24.3 gC m−2 day−1 and was affected strongly by nutrient concentrations. Average NEP ranged from 2.9 to 9.2 gC m−2 day−1, suggesting the potential of some of the evaluated ecosystems to be CO2 sinks. Within this review, the large spatiotemporal range allows for a wide‐ranging understanding of the variation of metabolic processes which contribute to CO2 dynamics and the role of aquatic ecosystems in regional climate change. Additionally, by evaluating aquatic ecosystem metabolism across such a diverse range of environmental conditions this work provides a scientific basis for future assessments of ecological risks under the complex conditions of climate change.

Rapid urbanization, aging infrastructure, and climate change impacts have put a strain on existing stormwater drainage systems. One commonly acknowledged solution to relieve such stress is Green Stormwater Infrastructure (GSI). Interest in GSI technology has been growing. However, the level of implementation in many areas around the world lags behind the interest level. This study aims to critically review the body of literature from the last decade to determine the main barriers to wide adoption and the offered solutions to overcome them. Based on a review of 92 peer‐reviewed journal articles published between 2012 and 2022, we classify barriers and solutions into six categories: socio‐cultural, financial, institutional and governance, legislative and regulatory, technical, and biophysical. Based on observations and conclusions from the reviewed articles, we recommend the following pillars and considerations for more GSI adoption: increasing awareness and outreach programs; enhancing knowledge and data co‐production and dissemination; acknowledging interdependency and context‐specificity of many of the challenges and solutions; prioritizing integrated and participatory watershed planning; overcoming institutional path‐dependencies; prioritizing innovative solutions; giving specific consideration to maintenance protocols; considering the role of public entities; and actively engaging with communities.
