The Second Performance Review of the Green Climate Fund covers the GCF-1 period and seeks to inform, among other things, the next update to the strategic plan (USP-2), currently being discussed for the GCF-2 period (2024–2027). The scope of the SPR includes (1) evaluating the GCF’s progress in delivering on its mandate as set out in the GI and its strategic and operational priorities and actions as outlined in the USP, and (2) the performance of the GCF in promoting a paradigm shift towards low...
The Deciding Factor: Analyzing the Number and Modality of Decisions Made by the Board of the Green Climate Fund
January 2023
This paper analyses the nature and quantity of decisions made by the Board of the GCF during 2020 and 2021. The paper aims to illustrate the mechanics of the decision-making of the Board that will aid assessment of the effectiveness and efficiency of the GCF’s governance.
Evaluability assessment of the Green Climate Fund funding proposals
December 2022
This paper continues IEU’s effort to assess the tools and frameworks within funding proposals that enable robust monitoring and measurement of results during project implementation. The series began in 2019 with “Becoming bigger, better, smarter: A summary of the evaluability of Green Climate Fund proposals”. This paper presents the progress in the ability of projects to deliver a cost-effective impact on climate adaptation and mitigation during the GCF-1 period.
Systematic review: Behavioural science interventions within the development and environmental fields in developing countries
December 2022
This paper presents a systematic review on behavioural science interventions in the human development and environmental/climate fields in developing countries. The review synthesizes evidence on five specific behavioural interventions – feedback, reminders, salience (communication), salience (experience design), and goal setting – and how these influence development and environmental/climate outcomes. It aims to facilitate the use of evidence in informing policy and practice decisions within...
Evidence gap map: Behavioural science interventions within the development and environmental fields in developing countries
December 2022
The evidence gap map (EGM) presents a report and online resource depicting the landscape of studies on the effectiveness of behavioural science interventions. It finds the most commonly evaluated interventions are reminders and feedback. Most studies are from the WASH, financial, energy/extractives, and agricultural sector. Studies report adaptation outcomes more frequently than on mitigation, especially regarding knowledge, uptake and use.
Evidence gap map: Interventions for women's empowerment in developing countries
December 2022
This evidence gap map plots studies on the effectiveness of interventions for women’s empowerment in developing countries. The evidence gap map shows most evidence is from Sub-Saharan Africa and South Asia, especially on economic interventions and capacity-building interventions. It serves as a useful visual resource to understand the areas where research on the effectiveness of interventions for women’s empowerment is concentrated and where it is lacking.
Systematic review: Effectiveness of life skills training interventions for the empowerment of women in developing countries
December 2022
The systematic review evaluates the ability of life skills interventions to promote the empowerment of women of all ages. Overall, life skills positively affect a range of self, social and economic empowerment outcomes. Small but significant positive changes were detected for a range of outcome areas including leadership, attitudes to gender issues, sexual and reproductive health and rights, employment and life skills themselves.
