A ‘thinned’ landscape, which provides far from ideal habitat for many species.
Legal vegetation 'thinning' is contributing to high rates of land clearing, potentially causing problems for threatened species and ecosystems.
By the end of the 1990s, the idea of encroaching deserts had become difficult to defend.
Africa's great green wall suffers from a major mismatch between ambition and effort. But that's not to say it should be ditched altogether.
Extreme weather could trigger ecosystem collapse, including mass tree deaths.

Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.
The urban landscape is complex and ever-changing in cities such as Perth, but digital aerial photography can now monitor even the smallest changes.
Constant, complex changes in cities and mine sites are hard to monitor. Drawing on digital aerial photography, it's now possible to track land-use and vegetation changes in areas as small as 10-20cm.
Do animals mind how densely vegetated their habitat is? Numbers of birds, reptiles and mammals have been recorded in sites…
The Diprotodon optatum, a marsupial mega-herbivore sometimes known as the Giant Wombat or the Rhinoceros Wombat, grew to three metres in length and two metres in height. Its closest surviving relatives are the wombat and the koala.
The first Australians hunted giant kangaroos, rhinoceros-sized marsupials, huge goannas and other megafauna to extinction shortly after arriving in the country more than 40,000 years ago, new research…
