The Eighth Comprehensive Evaluation of the GEF (OPS8) will provides a comprehensive evaluation of GEF's interventions across various environmental domains. This report will assess the effectiveness, efficiency, and relevance of GEF's strategies, including result-based management, country engagement, private sector involvement, agency cooperation, support for innovative approaches, and considerations for gender, inclusion, and fragility. By triangulating inputs from diverse sources of evidence, the final report offers a robust evaluation framework that informs future GEF programming and policy decisions.
