Peatlands in Indonesia are of global significance for biodiversity conservation and climate regulation, as well as of national and local significance for water management and livelihood support. Despite their importance, in tropics these ecosystems remain among the least investigated and monitored and are increasingly threatened by anthropogenic activities. To support the ongoing formulation, refinement and implementation of peatland restoration and conservation activities in Indonesia, we developed a methodology based on land cover and land productivity analysis, which will help prioritize interventions in Sumatra, Kalimantan and Papua. Results showed that of the analysed peatland area, approximately 45.5% should be conserved, 28.7% should be restored and 16.2% should be subjected to sustainable agricultural practices. Furthermore, the analysis showed that only 15.6% of the peatlands in need of conservation measures are currently protected, resulting in a necessary expansion of protected areas of about 84%. This study is intended as a tool for policy makers to guide future action, emphasising that conservation and restoration efforts in Indonesian peatlands should be increased, and providing spatial guidance for their implementation.
