Humans evolved to be the water-saving ape

A new study reveals that humans use 30% to 50% less water per day than chimpanzees and gorillas. This finding suggests an ancient shift in the human body's ability to conserve water, enabling early humans to venture farther from streams in search of food.

Predicting urban water needs

A Stanford University study uses Zillow and census data to identify residential water use patterns and trends in different community groupings. The research found that income levels do not always correlate with water usage, and that changing community development can impact water consumption patterns.

Cassava may benefit from atmospheric change more than other crops

A recent study found that cassava can maintain its nutritional quality and photosynthetic efficiency even under elevated carbon dioxide levels. The crop showed significant yield increases of 22-39% in various varieties, making it a promising option for smallholder farmers in sub-Saharan Africa.

In a warming world, Cape Town's 'Day Zero' drought won't be an anomaly

Researchers warn that extreme events like the 'Day Zero' drought could become common by the end of the century due to climate change. The study used high-resolution simulations to conclude that human-caused climate change made the drought five to six times more likely, and such events could impact regions with similar climates.

Study finds that water efficiency achievable throughout US without decree

A recent study published in Environmental Research Letters suggests that targeted efforts to increase water efficiency can save enough water annually to fill Lake Mead. The research found that some regions and industries have the greatest potential for water savings, with improved water productivity in corn, cotton, and alfalfa contrib...

Study identifies first step to beating water scarcity

A new US study reveals that improving water productivity in certain regions and industries can help conserve water. By setting realistic benchmarks, the research found that areas with high water stress have the most potential for water savings, with around half of those gains coming from agriculture and manufacturing sectors.

A watershed moment for US water quality

A new federal rule leaves millions of miles of unconnected US streams and acres of wetlands unprotected, potentially undermining decades of taxpayer investment in improving water quality. The move risks higher floods, loss of biodiversity, and threats to drinking water and recreational fishing.

Less water could sustain more Californians if we make every drop count

California cities can rely on six key strategies to provide for growing populations: conserving water through behavioral changes, reusing non-potable water for irrigation, recycling water for drinking, capturing stormwater runoff, and desalinating seawater. These measures can help reduce costs while increasing the state's water supply.

Earth Day alert to save our frogs

A new study warns of amphibian conservation shortfalls due to climate change, highlighting the need for intelligent manipulation and management of water resources. Researchers found that extending temporary pool availability, restoring natural drying patterns, and releasing environmental flows can improve breeding outcomes.

Planning for future water security in China

A new study found that China's water use has decelerated since the 1980s due to the adoption of efficient irrigation techniques and industrial water recycling technologies. However, uncertainties remain due to land institution transitions, urbanization, and potential increased water use in intensive farming and industrial sectors.

Smart irrigation model predicts rainfall to conserve water

A predictive model combining plant physiology, soil conditions, and weather forecasts helps make informed decisions about irrigation, conserving up to 40% of water used. The research also aims to identify the best method for each crop and determine the costs and benefits of switching to an automated system.

Wagers winter plants make to survive

Ecologists at the University of Arizona identified a tradeoff between water use and reproduction that allows winter desert plants to survive. The study found that plants conserving water and growing slowly, or spending water by tracking rainfall, are best balanced along this tradeoff.

Integrated pathways for meeting climate targets and ensuring access to safe water

The study developed three water sector development scenarios to compare costs and impacts of achieving SDG6 goals and meeting climate targets. The analysis shows that combining clean water and climate policies can increase implementation costs, but these increases are relatively small compared to the cost for implementing each policy o...
