Resumo

Ecological restoration has received increasing attention as international agreements have set ambitious goals tc mitigate environmental change and reshape degraded landscapes. However, current restoration activities sometimes remain modest in their success. In particular, tropical forest restoration has had mixed outcomes wilt variable cost-efficiency. Here, we address the need for taking into account the spatial context of restoration tc inform policy initiatives that aim to improve the ecological and economic effectiveness of restoration. We ac{''} cessed the spatial distribution of relevant characteristics for ecological restoration in an emblematic heavily degraded tropical region: Sao Paulo state, Brazil. We compared statewide patterns in soil erosion risk, distance tc remnant habitat, and agricultural land use, to their characteristics in land voluntarily offered for active re storation. Based on this comparison, active restoration is likely to take place through small, low-priced parcels of land, usually in the context of substantial soil erosion risk and exacerbated deforestation. Restoration ecology predicts the need for expensive actions to assist a limited recovery process in such highly degraded conditions This general pattern also suggests the necessity for long-term commitment among a broad set of social actors combined to mitigation of degradation in adjacent remnants and agricultural lands. Active restoration may be complemented by spontaneous regeneration in areas with less adverse conditions. Policy makers therefore neec to consider the complementarity of lands voluntarily offered for restoration, and land made available for re storation through other mechanisms. Our findings, likely applicable to other densely populated tropical regions suggest that land-use policies need to address drivers of restoration success at a fine-scale to enable effective strategies. We suggest this can be achieved by spatial analyses that incorporate biophysical features that de termine restoration opportunities and the likelihood of success. (AU)
