Data centres and democratic decline could lead to more water conflict in the future

To protect our planet’s waters, we need to better understand these new economic and technological factors that underlie disputes over water.

Why safe water is still lacking in the Marajó Archipelago, one of the world’s most water‑abundant regions

Brazil holds 12% of the world’s freshwater reserves and yet growing water insecurity reveals some of the country’s deepest sanitation inequalities, which are particularly relevant to Marajó, its largest coastal island.

From invasive species tracking to water security – what’s lost with federal funding cuts at US Climate Adaptation Science Centers

The people who manage America’s aquifers, wetlands, shorelines and recreation areas rely on federal science as they face new and rising risks in a changing climate.

Governments, universities and non‑profits must work together to safeguard Canada’s lakes and rivers

With federal departments facing budget cuts, protecting the Prairies’ waters will require a nimbler, collaborative model.

Coastal wetlands can’t keep pace with sea‑level rise, and infrastructure is leaving them nowhere to go

A coastal scientist explains why marshes, mangroves and other wetlands can’t keep up with the effects of climate change, and how human infrastructure is making it harder for them to survive.

Water woes in southern Alberta could spell disaster for aquatic ecosystems, and the people who rely on them

Declining precipitation, climate change and governance failures will drive water flow scarcity in 2024 with serious implications across Western Canada.

Ripple effect: How public attitudes can shift governments toward sustainable, and resilient, water systems

The results of a new study are clear: resilient water governance systems are effective and enjoy strong public support. The time is now to build resilience into our global water systems.

What Arizona and other drought‑ridden states can learn from Israel’s pioneering water strategy

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.
Following historic drought in 2021, reservoir levels dropped down in the Hoover Dam on the Colorado River, which gets its waters from the melting snowpack from the Rocky Mountains of Colorado and Wyoming. (pxhere.com)

Scientists dig deep and find a way to accurately predict snowmelt after droughts

Unprecedented droughts leave the subsurface drier than usual, affecting water supply in subsequent years.

If more houses had water butts, it could help with drought, flooding and water pollution

Extreme weather is set to dominate our future – can collecting rainwater reduce the threat posed by both drought and flooding?
