Stemming the water crisis in the western US will require cities and rural areas to work together to make water use on farms – the largest source of demand – more efficient.

Indonesia has a nature-based solution for when solar power isn’t being generated: its enormous potential for off-river pumped hydro energy storage.
Lake Powell’s water level has been falling amid a two-decade drought. The white ‘bathtub ring’ on the canyon walls marks the decline.

Climate change is affecting hydropower in different ways across the country.
The white ‘bathtub ring’ around Lake Mead, shown on Jan. 11, 2022, is roughly 160 feet high and reflects falling water levels.

The Colorado River provides water and electricity to 40 million people in the western US, but falling water levels threaten both of those resources.
Dalat, a region in the central highlands of Vietnam, is known for its fertile land and the fruits and vegetables that grow there. As a consequence, interest in the Department of Agriculture at the Dalat Vocational Training College is high.

Data analysis suggests local activity will intensify the effects of global warming - so adapting means rethinking national development strategies
The U.S. has thousands of lakes and reservoirs that could be paired for pumped hydro storage without the need for rivers.

A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.
A study points to one way to speed up adoption of innovations in clean energy technology – more flexibility among state regulators.
Maine’s Penobscot River flows freely where the Veazie Dam once stood. Dam removals have reopened the river to 12 native fish species.

Thousands of dams across the US are aging and overdue for maintenance. Taking them down can revive rivers, restore fish runs and create new opportunities for tourism and outdoor activities.

The Nile Treaties prevent upstream countries from using the waters of the Nile without the consent of those downstream. This results in an Egyptian bias.
The Ganges delta spans India and Bangladesh and is home to more than 100m people.

Sea levels are rising, while deltas are being starved of sediment by upstream dams.
Renewable energy being installed at a community in the Northern Territory. Researchers have predicted Australia’s emissions are set to fall, but warn the renewables deployment rate must continue.

Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
These photovoltaics panels provide this village with energy now, but they could become obsolete when the main grid arrives.
