Cost–benefit analysis (CBA) of forestry instruments compares their economic, social, and environmental costs and benefits to guide policy choice. Key instruments: regulatory (protected areas, logging bans), market-based (timber concessions, PES, carbon credits), incentive-based (subsidies, tax breaks), and participatory/community approaches (co-management, tenure reforms). For each instrument, identify direct costs (implementation, enforcement, transaction, opportunity) and benefits (timber/NTFPs, carbon sequestration, watershed services, biodiversity, livelihoods, avoided damages). Value using market prices, avoided-cost, production-function, ecosystem-service valuation, or stated-preference methods; apply social cost of carbon where relevant. Discount future flows, run sensitivity and scenario analysis, and model uptake and leakage. Evaluate distributional impacts and governance risks (corruption, tenure conflict). Decision metrics: NPV, BCR, IRR, plus multi-criteria analysis for non-monetary values. Recommend instruments with positive net social returns, feasible governance, and equitable benefit-sharing, and include monitoring and adaptive management.
