This report is an independent, end-of-phase evaluation of the Africa Adaptation Acceleration Program (AAAP) conducted by Boston Consulting Group. The report seeks to assess AAAP’s performance against its stated objectives, the extent of its impact, its value-for-money and key lessons learned across activities between 2021 and 2025. Activities outside the AAAP, such as our global advocacy and research programmes, fall outside the scope of this review.
