Zimbabwe, home to more than 14 million people, is currently facing a severe economic crisis. Under President Robert Mugabe’s land distribution reforms, in the year 2000 all white-owned commercial farms were forcibly seized for redistribution to landless native Zimbabweans.

Many of the world’s protected areas may not be located in the areas that need them the most, according to a recently published study in the journal PLoS ONE. The study examined the effectiveness of Peru’s existing protected area system in holistically preserving the biodiversity in this megadiverse country, finding it inadequately protecting many of the country’s species.

In a study published recently in PLOS ONE, researchers examined Peru’s network of protected areas. They found that many of these don’t exist in the areas most important for preserving the country’s biodiversity and addressing its threats, and suggest alternatives to make the system more effective.

For 10 million years the Indonesian island of Sulawesi has been disconnected from other landforms, almost inviting evolution to color outside the lines.
