The document discusses the challenges of designing successful REDD+ projects that both reduce deforestation and involve local communities. It shares lessons learned from the Mpingo Conservation and Development Initiative (MCDI) in Tanzania. The three key lessons are: 1) assess the specific drivers of deforestation to design effective interventions; 2) understand carbon market requirements to satisfy validation schemes; and 3) balance community engagement with contractual uncertainties in early project design phases. REDD+ brings business aspects like carbon markets to conservation, requiring demonstration of overall emission reductions beyond single forest patches.
