Landscape restoration: Is it working?
A recent study by scientists at University College London (UCL) and the University of Edinburgh has raised concerns about the Bonn Challenge, questioning the impact the implementation of its goals are likely to have on climate change.
Their paper was recently published in Nature, and suggests that current plans by countries pledging areas for planting trees as part of the Challenge might not meet the goal fo the Intergovernmental Panel on Climate Change (IPCC) to limit global warming to 1.5 degrees Celsius..
The researchers wanted to “look at the big picture,” says Simon Lewis, lead author of the paper and professor of global-change science at UCL. “It makes sense on a local level to have the land required to produce all sorts of social, economic and environmental benefits,” he says. “But when you zoom out and look at the aggregate effect of all those decisions, then we don’t get to the place where we want to get to.”
