Agricultural trade and its impacts across population groups
The nexus of water, agriculture, and trade has global implications on multiple Sustainable Development Goals (SDGs), especially for the most vulnerable populations. The study by Weiyi Gu and colleagues finds striking trade-induced asymmetric water impacts across population groups. It thereby underscores that international agricultural trade eases water scarcity yet exacerbates inequity, disproportionately favouring more affluent populations. The authors urge future water and trade policies to strive for a better balance across multiple critical SDGs to achieve sustainable development for all.
Water can be a tool for peace and prosperity. But water can also create tensions if usage is unfairly shared. World Water Day 2024 focused on the importance of working together to make water a catalyst for a more peaceful society.
Access to clean water is a fundamental human right, yet over two billion worldwide lack this essential resource close to their homes. This scarcity fuels conflict and hampers development globally. Despite the situation’s gravity, I am steadfast in my belief that these challenges can be overcome.
Water commons are water resources collectively managed and utilized by communities as common property to support their food security, traditions, and livelihoods. Water commons are under increasing pressure of acquisition, privatization, and grabbing. This Comment analytically defines the water commons, examines their vulnerability to grabbing, and discusses the associated water justice and environmental implications.
The use of widely available groundwater and remote sensing data allows the identification of depth to groundwater thresholds to maintain water-dependent vegetation health.
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.
A membrane inspired by the arsenic–protein interactions in biological systems allows the efficient removal of various arsenic species from contaminated water.
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.
Electricity trade between Ethiopia, Sudan and Egypt is proposed as a mechanism for alleviating Nile water disputes. Simulations show potential benefits, including reduced water deficits, lowered emissions and increased financial returns.
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.
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.
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
This paper explores legal processes for penalty setting in water theft cases in transboundary water systems and develops ideas to identify differences and potentially drive consistency between jurisdictions.
