A new WWF report has revealed how and why our planet has lost an area the size of California to deforestation in just over a decade.

Mapping Together helps people use Collect Earth mapathons to monitor tree-based restoration. Collect Earth enables users to create precise data that can show where trees are growing outside the forest across farms, pasture, and urban areas and how the landscape has changed over time.

A new report from WRI India found that the Sidhi district could economically and ecologically benefit from landscape restoration. When implemented at scale in Sidhi, restoring land could conserve biodiversity, improve water recharge, sequester carbon, enhance rural livelihoods and spur rural development.

This new WRI report estimates that legal and illegal mining in the Amazon now cover more than 20% of Indigenous lands – over 450,000 square kilometers. It also finds that Indigenous lands with mining experienced higher incidences of tree cover loss than on those without – at least three times greater in Bolivia, Ecuador and Peru.

The global Living Planet Index continues to decline. It shows an average 68% decrease in population sizes of mammals, birds, amphibians, reptiles and fish between 1970 and 2016. A 94% decline in the LPI for the tropical sub regions of the Americas is the largest fall observed in any part of the world.
