India’s new manual for water supply will replicate past failures

Achieving continuous supply requires both a realistic assessment of the situation and a realistic plan to meet the goal. The Government of India’s new initiatives have neither.

Solving water challenges is complex – learn how law, health, climate and Indigenous rights all intersect in developing solutions

A webinar hosted by The Conversation brings together experts in law, health, policy and Indigenous affairs to explain some of the most pressing problems related to water in the US.
Fires are increasing in high mountain areas that rarely burned in the past. John McColgan, Bureau of Land Management, Alaska Fire Service

Fire danger in the high mountains is intensifying: That’s bad news for humans, treacherous for the environment

Fires here can affect meltwater timing and water quality, worsen erosion that triggers mudslides, and much more, as two scientists explain.
Hundreds of freshwater basins across the world, including the dried-up Santa Olalla permanent freshwater lagoon, in Spain’s Doñana National Park, are the most likely to experience social and ecological impacts due to freshwater use. (Donana Biological Station/CSIC)

Ripple effect: As global freshwater basins dry up, the threat to ecosystems and communities grows

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.
Stalagmites grow from the cave floor up as water drips down. Gayatri Kathayat

1,000-year-old stalagmites from a cave in India show the monsoon isn’t so reliable – their rings reveal a history of long, deadly droughts

As water dripped in a remote cave, it left behind evidence of every monsoon season for a millennium. Scientists say it holds a warning for a country about to become the most populous on Earth.

Grim 2022 drought outlook for Western US offers warnings for the future as climate change brings a hotter, thirstier atmosphere

La Niña is only part of the problem. The long-term driver of increasing drought – even in areas getting more rainfall overall – is the rapidly warming climate.

Satellites over the Amazon capture the choking of the ‘house of God’ by the Belo Monte Dam – they can help find solutions, too

When Indigenous peoples lose their river flow to dams, satellite programs like Landsat – which is celebrating its 50th anniversary – can help them fight for their resources.

US climate risks are rising – a scientist looks at the dangers her children will have to adapt to, from wildfires to water scarcity

The author’s 9-year-old son will likely face about four times as many extreme events in his lifetime as older adults today. An international report explains the impacts already being felt.

IPCC report: Half the world is facing water scarcity, floods and dirty water — large investments are needed for effective solutions

Water is central to adapting to climate change, but very few of the strategies put in place to respond to water hazards or ensure its availability have been evaluated.
