Injecting Biodiversity into City Spaces

By Nathalie Butt

Cities planning to adapt to climate change should take biodiversity along for the ride.

More than half of the world’s people live in cities, and this will reach two-thirds by 2050. Most cities are situated on coasts or rivers, and currently more than 400 cities across the world are directly threatened by sea level rise, putting more than 400 million people at risk.

The Third Dimension of Conservation

The ocean realm is fundamentally a three-dimensional space. Conservation planning in such conditions is more efficient when features and threats can be stratified with depth. Credit: Thomas Vignaud

Oceans are inherently three-dimensional spaces, so effective and efficient conservation planning in oceans should take this third dimension – depth – into account.

Human Burials Can Save Threatened Species

By Matthew Holden

As declines in biodiversity accelerate we need to examine innovative ways to save threatened species. Conservation burials may be one solution, and the potential is enormous.

Revolving Private Land to Conserve Nature

By Mat Hardy, Sarah Bekessy, James Fitzsimons & Ascelin Gordon

Buying, protecting and reselling private land can be an effective way to conserve nature, but relies upon selecting the right properties.

The acquisition of private land with significant conservation value can be a powerful way to protect important species and ecosystems. But acquisition can be expensive, particularly in areas where land values are high. An alternative to buying land and creating a conservation reserve is to enter into permanent agreements with private landholders (e.g. conservation covenants) that restrict both current and future landowners from conducting activities that would harm their land’s ecological value.

South Australia Doubles Down on Solar Energy

By Ian Lowe

A South Australian election promise to install solar panels and batteries in 50,000 homes has placed the Prime Minister in an awkward position.

The calling of a state election in South Australia put electricity prices in the spotlight. The 100 MW Tesla battery has proved a great success, not just evening out power supply for South Australia but helping out Victoria when a Latrobe Valley brown-coal generator shut down on a hot afternoon.

Planning for an Expanding Ice-Free Antarctica

By Jasmine Lee

Climate change will increase the amount of ice-free land in Antarctica by 25% this century.

Mention Antarctica and nature, and most people think killer whales, seals and penguins. But there is so much more when it comes to biodiversity on this frozen continent. Often overlooked is a large suite of native species only found on the land. This terrestrial biodiversity consists of microbes, moss, lichen, two native plants and a large array of invertebrates including tardigrades, springtails, nematodes and mites. Some of these species occur nowhere else in the world and have developed a range of amazing adaptations to survive.

Orangutans (and Science) Are in Trouble

By Kerrie Wilson

Robust science is telling us orangutan populations are in serious decline but the Indonesian government is disputing the finding.

Recently we published the first ever population trend analysis of the Bornean orangutan, showing that the species has declined at a rate of 25% over the past 10 years. This rate of decline was sufficient for the IUCN to elevate the conservation status of this species to Critically Endangered last year.
