As surface water diminishes in the Western US, people are drilling deeper wells – and tapping into older groundwater that can take thousands of years to replenish naturally.
African farmers need homegrown solutions to improve food security.
Barriers to independent national decision making in farming need to be challenged if agricultural sustainability is to be developed.

The US has one of the highest groundwater use rates in the world. When wells run dry, households may opt to conserve water, find new sources or sell and move.
New research finds water markets in the southern Murray-Darling produce benefits of around $117 million per year.
First Nations people have almost no say in how water is used in Australia. The Productivity Commission’s latest report does little to address that.

An invisible crisis is brewing in US farm country as the overpumped Ogallala-High Plains Aquifer drains. The key drivers are federal farm subsidies and the tax code.

Marking farms more water-efficient pushes up prices twice as much as buying water back.
Knee-jerk responses to water insecurity won’t fix the basin. The harder and longer path is delivering real water reform, including transparent water planning enshrined in law.

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.
Waters from the Herbert River, which runs toward one of northern Australia’s richest agricultural districts, could be redirected under a Bradfield scheme.
The ‘New Bradfield’ scheme seeks to revive a nation-building ethos supposedly stifled by bureaucratic inertia. But there are good reasons the scheme never became a reality.
The Delta’s rich array of wildlife makes it a popular tourist destination.
It’s imperative that we understand what creates and sustains the delta for the future management of the system.
The push to ‘drought-proof’ Australia is dangerous nonsense.

Yes, Australia naturally cycles through dry and wet periods. But that doesn’t mean we can simply build more dams and trust they’ll be filled.
Innovation in digital technology is accelerating – it has massive untapped potential for tackling the climate crisis.
Let’s say we took a lot of water from the coast and piped it to a dry inland area. How might that affect the soil in both places?
The Australian landscape is very old and the soils in inland areas can be very fragile.
After years of delay, the New Zealand government is pushing ahead on a national plan to clean up the nation’s lakes, rivers and wetlands.
A proposed plan to clean up New Zealand’s waterways draws clear limits on the expansion of dairy farming and irrigation, as well as on the use of nitrogen fertiliser in some key areas.
Harvesting wheat in the Peruvian Andes.
Peruvian glaciers have shrunk by 25% since 1987, causing water shortages in rural villages. But ancient technology could help manage this precious resource.
There’s broad support from communities and farmers for proper water audits.
How can Australia’s new Inspector General be expected to inspect waterways without a firm grasp of how much water in in them?

Good news – underground aquifers could be a reliable source of drinking water in sub-Saharan Africa even as the climate warms.
