In this chapter, we synthesize what these diverse experiences tell us about the capability of REDD+ to deliver on its goals, including the role of subnational initiatives and how they integrate with national REDD+ through their choice of (i) scale and (ii) MRV systems. Our research on these initiatives also gives us insights into the challenges of (i) financing interventions, (ii) clarifying tenure, and (iii) designing social safeguards. In particular, our rich data on household livelihoods and village conditions allow us to identify common patterns as well as heterogeneity that must be taken into account in the design of social safeguards. For each of these five issues, we first note some of the key insights from the literature and then summarize what we have learned from the case studies. We close with a section assessing whether REDD+ still has the potential to be the path-breaking solution to deforestation that generated so much hope and enthusiasm seven years ago.
