It’s time for a global landscape restoration revolution
The solution to the very visible global problems of deforestation, desertification and food scarcity may be hiding in plain sight: the transformative ability to restore degraded land to productive use.
This is a resource opportunity of unprecedented magnitude. Two billion hectares— an area twice the size of Europe — of degraded land are ripe for landscape restoration. The expected rise in world population to 9 billion by 2050, and the need for a 70 percent increase in food production from 2006 levels, makes the need for a solution particularly urgent. This challenge will be even more difficult in the face of a changing climate.
Restoring these degraded lands would also be a huge blessing to millions of small farmers who depend on agriculture for their livelihoods — and it offers the additional benefit of mitigating climate change while helping farmers adapt to it. Restoring 150 million hectares would yield $84 billion in annualized net present value and would sequester approximately 1 gigaton of carbon dioxide equivalent annually.
What is required now is the political momentum to do so.
