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.","ai_generated":true,"unit":"iisd-003453#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"A combined package of peatland interventions—blocking canals, revegetating, monitoring land use, and improving fire suppression—yields the highest cumulative net benefit for society, totaling USD 4.136 million by 2100.
