Given that total rangelands (a) can have different levels of management and grazing intensity and hence biodiversity richness, we use the Very Low Human Influence (VLHI) map based on Riggio et al.127 (b) to filter out grazing land that can be considered closer to a pristine state. Combined with pasture, the remaining available grazing land (c) constitutes the total grazing land that is considered for AR (d) in our framework. Available rangeland is further categorized into 4 biodiversity groups (e), based on the Low Human Influence (LHI) map based on Riggio et al.127 (f). The Griscom et al.19 restoration potential map (GRS, (g)) and Atlas of Forest and Landscape Restoration Opportunities126 (ATL, (h)) are further used to guide the spatial pattern of AR, given an annual AR target for each world region. Allocation of the AR target across the gridcells is performed using the iterative process presented in the “Methods” section. The resulting AR pattern by 2100 for the target set in this study is presented in (i).
