Restoration Opportunities Assessment Methodology (ROAM) will help countries understand how much of their land offers restoration opportunities, map where those opportunities are and determine which degraded landscapes offer the most value to society. Global analysis has found more than two billion hectares of land across the planet that could benefit from restoration. What do these opportunities look like at the necessary, landscape level? Where should countries, organizations, and individuals interested in restoration begin?ROAM, produced by IUCN and others, notably WRI, also offers a tangible first step for countries interested in committing to the global ‘Bonn Challenge’ goal to restore 150 million hectares of degraded and deforested lands by 2020. With several countries already having made pledges totaling 20 million hectares, the Bonn Challenge represents the largest restoration movement the world has ever had.
