Humans are causing massive changes in the location of water around the world, NASA says

A 14-year NASA mission has confirmed that a massive redistribution of freshwater is occurring across Earth, with middle-latitude belts drying and the tropics and higher latitudes gaining water supplies.

The results, which are probably a combination of the effects of climate change, vast human withdrawals of groundwater and simple natural changes, could have profound consequences if they continue, pointing to a situation in which some highly populous regions could struggle to find enough water in the future. ...

The world's poorest countries are making progress toward the United Nations' sustainable energy goals, but not as quickly as development agencies had hoped, according to a new report from the UN, the World Health Organization and three other international agencies.

Of the 1 billion people who lack access to electricity, mostly in sub-Saharan Africa and South Asia, only about a third will get it by 2030, they found, and more than 2 billion will still be cooking with unhealthy, polluting fuels. ...

More than 5 billion people could suffer water shortages by 2050 due to climate change, increased demand and polluted supplies, according to a UN report on the state of the world’s water.

The comprehensive annual study warns of conflict and civilisational threats unless actions are taken to reduce the stress on rivers, lakes, aquifers, wetlands and reservoirs. ... Read more about Water shortages could affect 5bn people by 2050, UN report warns

The Water-Energy Challenge Water and energy are interlinked. Significant amounts of water are needed in almost all energy generation processes, from generating hydropower, to cooling and other purposes in thermal power plants, to extracting and processing fuels. Conversely, the water sector needs energy to extract, treat and transport water. Both energy and water are used in the production of crops, including those used to generate energy through biofuels.

A solar-powered water harvesting device, constructed with a metal organic framework. Unlike other types of water capture devices, this design is able to work under low-humidity conditions. (Hyunho Kim, Evelyn Wang)

A new kind of water-capturing device could be a game-changer for some of the world'€s driest places. It can pull water vapor out of the air at humidity as low as 20 percent €- conditions that may be seen in the Sahara desert during its hottest months €- and it can operate entirely off-grid, just using the ambient power of the sun. ...

Demand for the metal used in electric car batteries has surged. But extraction could threaten the fragile ecosystem of the world’s largest salt flat.

Demand for lithium – which is used in pharmaceuticals, fertilisers, and smartphone and electric car batteries – has surged in the past year, ahead of an anticipated boom in electric cars, and is projected to outstrip supply by 20 ...
