Notes de l'éditeur
- Missing the PNG (the whole NG Island is about 16Mha of peatlands)-
- About half of the world's tropical peatlands occur in Southeast (SE) Asia, where they serve as a major carbon (C) sink. Nearly 80% of natural peatlands in this region have been deforested and drained, with the majority under plantations and agriculture. This conversion increases peat oxidation which contributes to rapid C loss to the atmosphere as greenhouse gas emissions and increases their vulnerability to fires which generate regional smoke haze that has severe impacts on human health Carbon gains and losses from pristine and degraded peatlands. Thickness of arrows indicates relative magnitude of flux in pristine versus degraded peatlands. OM = organic matter; C = Carbon
- Indonesia has the ambitious vision to restore more than 2 Mha of degraded peatlands. Our study identified 341 peatland restoration sites in Indonesia between 1992 and 2019 (Figure 1). Projects are still short terms so still tentative. Average cost is about 500$ ha-1 yr-1.
- Out of the 341 recorded actions, 217 sites reported success and an analysis of a 95 site subsamples showed the most important drivers for success.
- CIFOR organized a series of online workshops between September and December 2020, to explore and identify criteria and indicators for tropical peatland restoration through a consultative process involving practitioners, government agencies, researchers and community members. From this process it emerged that effective criteria and indicators for peatland restoration should capture aspects relating to rewetting drained peatlands, reducing fire risks, revegetating landscapes, reinforcing local governance structures, and revitalizing local communities’ socio-economic conditions (five Rs).
- The identified criteria and indicators cover four aspects of peatland restoration – biophysical, social, economic and governance – to capture the range of topics and issues that impact peatlands. These criteria and indicators are now ready for field testing, and when these have been successfully validated, can be adapted and adopted by relevant agencies for future restoration monitoring.
