Appendix to STAP’s paper, “Achieving enduring outcomes from GEF investment”: a short literature review
This appendix reviews literature on sustainability and durability in project outcomes, coupled with scaling of impact and sustainability of projects in the face of future change. About 100 sources were reviewed, including mostly peer-reviewed literature but also assessments of project portfolios by a range of development funders and foundations. This appendix summarizes key findings from this literature outside the GEF family of reports from STAP and the IEO. The main text draws selectively on this appendix, and also links it to findings framed by GEF publications.
