Land clearing rates in Queensland tripled since 2010. Martin Taylor

Queensland land clearing is undermining Australia’s environmental progress

Land clearing in Queensland has tripled in the past five years.
Cassava feeds 800 million people - keeping it disease-free is a must.

World hunger: what the Ebola virus can teach us about saving crops

Rapid genetic disease screening will be the key to saving East Africa’s crops - just as it was during West Africa’s ebola crisis.

Rising extreme weather warns of ecosystem collapse: study

Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.

CSIRO cuts: climate science really does need to shift its focus towards adaptation

Cuts to CSIRO climate jobs will see a reduction in effort on monitoring and measuring climate change, and an increase in efforts to do something about it. That’s the most politically-sensible option.
The world’s driest areas are tipped to get even drier, with potentially worrying implications for soil productivity.

If the world’s soils keep drying out that’s bad news for microbes (and people)

The world’s ‘drylands’ – already home to 38% of the world’s people – are set to dry out even more. And that could harm the soil microbes that keep soils healthy and help crops to grow.
Loving our monsters? We’ll learn more by researching sharks than by kiling them. ScreenWest/AAP

Relax, shark numbers aren’t booming, but more research can make us safer

The best way to guard against shark attacks is to study them, not kill them. Because while the alleged “shark boom” almost certainly not real, the more we know about sharks, the better.
The cover that trees provide transforms cities into much more hospitable places, especially in hot weather. AAP/Joe Castro

In a heatwave, the leafy suburbs are even more advantaged
