The world is facing an imminent water crisis, with demand expected to outstrip the supply of fresh water by 40% by the end of this decade, experts have said on the eve of a crucial UN water summit.

Australia may be the world’s leader in mammal extinction, with accelerating threats to native biodiversity in a changing climate – but successful conservation efforts may provide a glimmer of hope

The Australian government plans to make an area about the size of Germany in the Southern Ocean a marine zone, strengthening protections around Macquarie Island for millions of penguins and seals.

For the first time in history, Australia has blocked the creation of a coal mine under environmental laws.

Early modelling suggests the world’s climate could shift to an El Niño pattern towards the end of 2023, which is likely to increase the global average temperature

A new report by the United Nations Environment Programme warns that investment in nature-based solutions must double by 2025 if the world is to limit global warming to 1.5°C, as well as halting biodiversity loss and progressively increasing land degradation.

Cities are warming twice as fast as the global average. The Nature for Cool Cities Challenge seeks to enhance the number of nature-based cooling solutions within built-up city surface area

Vultures get a bad reputation for their carrion-scavenging ways, but their dietary habits prevent the release of greenhouse gases

Rising electricity costs are reducing the payback periods for the cost of solar panels and their installation to be fully recouped by savings on electricity bills

Throwing a lamb chop on the barbie is about as Australian as it gets, but many are seeking out alternative sources of protein amid growing concerns over food security, animal welfare and the environment.

Cawthron Institute has partnered with Westpac NZ Government Innovation Fund, Port Nelson and forestry company OneFortyOne to launch a seagrass restoration project that aims to fight climate change and improve ecosystem health.

A project to restore and protect the Maroochy River catchment as a solution to climate change has received a major grant. The Blue Heart project received $2 million from the Federal Government’s Blue Carbon Ecosystem Restoration Grants. The project aims to transition the Maroochy floodplain from its former uses as cane farms and other rural activities back to natural estuarine systems.

Oxford start-up Deep Planet is leveraging AI and satellite imagery data to help wine growers and producers adapt to climate change.

Addressing the twin challenges of carbon emissions and biodiversity loss requires political will and leadership. Ambitious commitments must be made

Thousands of kilometers of shoreline would qualify as cost-effective candidates for mangrove forest and coral reef restoration, thanks to their ability to reduce flooding, new research shows.

Advantageously, these super functional seedling pots solve the inherent problems with plastic pots: excess watering, nutrient runoff and transplanting needs.

The dam at Mt Keith is a leading global example of “mineral carbonation”, a chemical reaction triggered when the mine’s magnesium-rich wastes interact with air, leading to carbon dioxide being sucked out of the atmosphere and locked away in secure mineral crystals.

Australia has some 16 Pacific Island neighbours — some with a landmass a millionth our size — who unanimously declare climate change the “single greatest threat” to the region.
