Immigration isn’t the only hot-button issue along the US-Mexico border. There’s also a growing water shortage that’s affecting farmers, businesses and cities on both sides.
Local water conservation measures could buffer the potential negative impacts of climate change in eastern Africa and boost food production.
New research reveals the environmental impact of keeping tropical fish as household pets – but there are ways to reduce it.
Arizona is considering a multibillion-dollar desalination project to address its urgent water needs. Three water experts call for a go-slow approach and point to Israel as a role model.
In a preprint study, researchers estimate training the model behind ChatGPT would have required somewhere between 210,000 and 700,000 litres of water.
Southwest states have bought time with an agreement between California, Arizona and Nevada to cut Colorado River water use by about 14%. Now comes the hard part.
Two decades of drought have reduced the river’s flow by one-third compared to historical averages. The Biden administration is considering mandatory cuts to some states’ water allocations.
Even after January’s storms, California faces a water-scarce future. An economist and an engineer propose a way to test higher water prices as a conservation strategy without hurting low-income users.
As we set conservation goals for the next decade, we need to evaluate what worked and what didn’t in our efforts to meet the 2020 biodiversity conservation targets.
While we know how global changes in freshwater pose risks to humans and ecosystems, we know less about how people and ecosystems will respond to these global freshwater challenges.
As droughts intensify, how can we increase crop production in a sustainable way? This is a multidimensional scientific and societal challenge to ensure future food security.
Nearly 97% of the world’s water is in the oceans, but desalination is no magic bullet for water-stressed coastal cities.
Rationing water at home will benefit moisture-starved ecosystems.
