Introduction Methods Findings Conclusion

Summary

• >90% of studies do not enable us to measure policy impact on forest cover

• Several regions are understudied• Strong supportive evidence of PES’ positive impact on

forest cover• Other policy types have ambiguous outcomes• Little study of agriculture and social programs’ impacts

on forest cover

18

Introduction Methods Findings Conclusion

Research Agenda

• Need to develop systematic studies looking at the interactions of policies within well-defined sub-regions.

• Investigations should more carefully examine the impacts of agriculture & social programs
