Mindful of the negative impacts associated with coastal ecosystems degradation, the government of Indonesia has embarked on a blue economy strategy encompassing a range of initiatives, including tackling mangrove degradation and depletion. Recently, the government of Indonesia has set an ambitious target for mangrove restoration of 600,000 hectares by 2025. How this target can be reached and the implications of the actions to be taken are subject to national debate. The objective of this report is to inform sustainable mangrove management policies in Indonesia through quantification of the values and spatial variations of the net benefits of mangrove conservation and restoration. The report compares the costs and benefits of mangrove restoration and conservation using a nation-wide spatial cost-benefit analysis (CBA). The analysis is spatially explicit, meaning that variation in costs and benefits by location are assessed, helping to identify cost-effective locations for large-scale mangrove restoration and conservation. The results of this assessment should help the government, the private sector, and other stakeholders across Indonesia better understand the costs and benefits of mangrove management decisions.CC BY 3.0 IGOMANGROVE RESTORATION; OPPORTUNITY COST; SPATIAL DISTRIBUTION; COASTAL PROTECTION; MANGROVE MANAGEMENT; ECOSYSTEM SERVICE; NET PRESENT VALUE; NEGATIVE NET PRESENT VALUE; LAND USE; RESTORATION ACTIVITIES; BLUE ECONOMY; SUSTAINABLE USE OF MARINE; NATURE-BASED SOLUTIONS; SMALL ISLAND DEVELOPING STATES; GLOBAL CLIMATE CHANGE MITIGATION; MARINE AND COASTAL MANAGEMENT; DISTRIBUTION OF INVESTMENT; DISCOUNT RATE; HECTARE PER YEAR; OWNERSHIP SHARE TYPE; COST-BENEFIT ANALYSIS; MEDIUM-TERM DEVELOPMENT; ECONOMIC VALUATION; RATE OF DEGRADATION; FISHERIES; GHG EMISSIONS; COASTAL ECOSYSTEM; CLIMATE REGULATION; SUSTAINABLE MANAGEMENTReportWorld Bank10.1596/37605
