The report utilizes system dynamics modelling and financial analysis to evaluate restoration options for the Katingan peatlands and Belitung mangroves in Indonesia. It finds that sustainable management of these ecosystems provides high societal value across all simulated climate scenarios and offers a cost-effective method for climate change mitigation and community support. However, the report emphasizes that for land rehabilitation to be economically viable and lasting, local communities require additional income sources, such as tourism, to prevent a shift toward environmentally damaging activities like mining and plantations.

The report evaluates the economic viability of restoring peatlands in Central Kalimantan and mangroves in Belitung, Indonesia. It argues that land rehabilitation is most effective when implemented as a package of interventions—such as combining canal blocking, land-use monitoring, and fire suppression for peatlands, or pairing mangrove planting with ecotourism—rather than as isolated measures. For peatlands, the highest societal net benefit (USD 4.136 billion by 2100) is achieved through a combined approach, primarily driven by avoided carbon emissions and fire damages. For mangroves, rehabilitation is deemed economically viable only when linked to additional revenue streams like ecotourism, which provides sustainable livelihoods and prevents land conversion for tin mining. The analysis emphasizes that local community income is critical for long-term success, as without alternative revenue (e.g., carbon payments or tourism), communities may return to environmentally damaging activities.
