US sewage treatment plants likely don’t get rid of all the disease-causing protozoa, and monitoring discharged wastewater for it is difficult.
The good news is degraded soil can regain some of its lost heat protection. We can help ‘re-insulate’ the ground with practical farming methods.
Years of industrial expansion have boosted water demand, with no new sources coming online since 2016. Desalination and reclaiming sewage wastewater are among the current options.
There are ways to reduce emissions without sacrificing yield. A new study shows how, and looks at a technique billed as ‘climate-friendly’ that makes emissions worse.
Science can only change the world when societies decide to give it the means to do so.
Thousands of hectares of communal land set aside for smallholder farmers’ use in South Africa are lying fallow because of collapsed government irrigation systems.
The Southern Plains states get a severe drought about once a decade, but long-lasting droughts lately have been leaving farms, rangeland and water sources with too little time to recover.
Desalination of seawater and sewage treatment plants leave behind water that contains high concentrations of salt, metals and other contaminants. What if that water could be separated from the rest?
By boosting beneficial microbes, researchers hope to increase crop resilience while reducing the use of synthetic nitrogen fertilisers.
Africa’s drylands need support, but it shouldn’t overlook systems that people rely on.
Iran’s sprawling cities and irrigated agriculture, along with tight market controls, have left the country vulnerable to drought. There are steps that would help.
Africa is heavily dependent on agriculture. At this year’s COP30 conference, the continent needs to secure more funding to adapt land to climate disasters.
Consumer choices about what to eat and how much of it can affect how much water farmers need to use.
A new study is the first to define a safe operating space for the rivers of the Bangladesh delta.
A research team at Simon Fraser University has developed an AI-powered robot that can autonomously water plants and monitor plant health.
Ancient practices hold important lessons for farmers facing drying lands, but they were often more complex than modern societies realize. Glacier loss adds to the challenge today.
Small-scale irrigation schemes in southern Africa can produce more food, support more jobs and be more profitable for the local community.
The NT government has given billions of litres of water from the Roper River to irrigators. When will Australia start managing our rivers for the future?
Four urgent things need to be done in 2025 for Nigeria to feed its citizens better and ensure their food security.
