A membrane inspired by the arsenic–protein interactions in biological systems allows the efficient removal of various arsenic species from contaminated water.
Arsenic water contamination may affect spring water as well as water reservoirs around the world and requires the development of efficient and sustainable remediation technologies. A bioinspired porous membrane allows obtaining filtrated water with an As concentration below the recommendation from the World Health Organization.
An innovative approach for a portable water bottle utilizes walking-induced electrostatic charges to achieve highly efficient in-situ disinfection, providing a practical solution for ensuring clean water in decentralized environments.
The development of direct in situ disinfection methods in bottles is of vital importance for providing safe drinking water, especially in rural and disaster-stricken areas. Harvesting the electrostatic charges induced by walking can stimulate electroporation disinfection and provide readily available portable water for point-of-use applications.
The use of widely available groundwater and remote sensing data allows the identification of depth to groundwater thresholds to maintain water-dependent vegetation health.
This study demonstrates the evaluation of groundwater-dependent vegetation responses to changes in the depth to groundwater based on satellite-derived normalized difference vegetation index, a simple and practical approach that supports water and conservation management.
This work reveals that international agricultural trade eases water scarcity yet exacerbates inequity, disproportionately favouring more affluent populations, thus emphasizing the necessity for pro-poor policies for inclusive sustainable development.
Solar power desalination is a promising technology for clean water production in off-grid locations. Now a time-variant version of this technology overcomes the solar power intermittency that such desalination plants suffer from, hence reducing the need for costly batteries
An absence of precipitation combined with drying of the ground through evaporation can deplete fresh water crucial for societies and ecosystems. However, new research highlights a more remote driver of drought.
Research on the ecological impacts of drought has predominantly focused on the scarcity of water supply, often overlooking divergent ecosystem water demands across vegetation types, regions, and time. These diverse ecosystem water demands need to be incorporated into an effective ecological drought monitoring and assessment framework.
This Review highlights the strengths and limitations of deep learning approaches relative to traditional approaches, emphasizing their potential as a currently underutilized yet promising avenue for advancing our understanding of water-quality sciences.
Coagulation plays a crucial role in ensuring the safety of drinking water by removing natural organic matter. A comprehensive investigation of existing coagulation theories at the molecular functional group scale highlights the importance of the properties of natural organic matter on coagulation efficiency and provides valuable insights for predicting and achieving the efficient removal of pollutants by coagulation.
Coastal megacities, such as Shanghai and New York City, exhibit marked disparities in flood evacuation patterns for elderly residents. Risk-informed, strategic storm flood evacuation planning can significantly improve the overall performance of evacuee transfer for large coastal cities.
Irrigation has helped facilitate large gains in crop yields but comes at an increasing cost to water resources, complicating climate change adaptation.
Half of irrigation expansion in the twenty-first century has taken place in water-stressed areas, offering a mixed picture for simultaneously achieving future food security, water sustainability and climate resilience in global agriculture.
Exceptional streamflow and soil moisture conditions now occur on a substantial share of global land area and are much more frequent than in pre-industrial times. This marks a notable transgression of the new planetary boundary for freshwater change.
Rivers carry large quantities of carbon and form an important link between terrestrial, marine and atmospheric biogeochemical cycles, yet our observations of river carbon are severely limited. Here we provide a blueprint to build a global River Observation System that would improve our ability to observe and predict changes in this crucial piece of the global carbon cycle.
