Résumé
Amazonia became a target area for Payment for Ecosystem Services (PES) initiatives in deforestation. We analysed the implementation of a PES scheme in Acre (Brazil) by taking into account land use heterogeneity in an agricultural frontier. Justified by the modernisation of deforestation control policies, the programme promotes agricultural intensification through fire-free practices. In this way, the PES tends to focus on long-established settlements, where farmers are wealthier and the landscape is dominated by pasture. Agricultural intensification may be adapted to foster reforestation. In order to curb deforestation a specific policy is needed for targeting remote areas where initial stages of deforestation usually take place. By promoting only land sparing, PES programmes in Amazonia may lose sight of their socio-economic and environmental objectives due to limited spatial targeting.
