Background Across the globe, gender disparities still exist with regard to equitable access to resources, participation in decision‐making processes, and gender and sexual‐based violence. This is particularly true in fragile and conflict‐affected settings, where women and girls are affected by both fragility and conflict in unique ways. While women have been acknowledged as key actors in peace processes and post‐conflict reconstruction (e.g., through the United Nations Security Council Resolution 1325 and the Women, Peace and Security Agenda) evidence on the effectiveness of gender‐specific and gender‐transformative interventions to improve women's empowerment in fragile and conflict‐affected states and situations (FCAS) remains understudied. Objectives The purpose of this review was to synthesize the body of evidence around gender‐specific and gender‐transformative interventions aimed at improving women's empowerment in fragile and conflict‐affected settings with high levels of gender inequality. We also aimed to identify barriers and facilitators that could affect the effectiveness of these interventions and to provide implications for policy, practice and research designs within the field of transitional aid. Methods We searched for and screened over 100,000 experimental and quasi‐experimental studies focused on FCAS at the individual and community levels. We used standard methodological procedures outlined by the Campbell Collaboration for the data collection and analysis, including quantitative and qualitative analyses, and completed the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology to assess the certainty around each body of evidence. Results We identified 104 impact evaluations (75% randomised controlled trials) assessing the effects of 14 different types of interventions in FCAS. About 28% of included studies were assessed as having a high risk of bias (45% among quasi‐experimental designs). Interventions supporting women's empowerment and gender equality in FCAS produced positive effects on the outcomes related to the primary focus of the intervention. There are no significant negative effects of any included interventions. However, we observe smaller effects on behavioural outcomes further along the causal chain of empowerment. Qualitative syntheses indicated that gender norms and practices are potential barriers to intervention effectiveness, while working with local powers and institutions can facilitate the uptake and legitimacy of interventions. Conclusions We observe gaps of rigorous evidence in certain regions (notably MENA and Latin America) and in interventions specifically targeting women as actors of peacebuilding. Gender norms and practices are important elements to consider in programme design and implementation to maximise potential benefits: focusing on empowerment only might not be enough in the absence of targeting the restrictive gender norms and practices that may undermine intervention effectiveness. Lastly, programme designers and im...

This review builds on 3ie's (international initiative for impact evaluation) evidence gap map (EGM) of the impact evaluation and systematic review (SR) evidence base of interventions aiming to promote peaceful and inclusive societies in fragile contexts. The EGM identified a cluster of studies evaluating gender equality‐focused behaviour change communication programmes and raised interest in investigating the evidence base for understanding the role of women more broadly as agents of change in developing peaceful and inclusive societies. Building on the cluster of evidence identified in the EGM, our review will increase generalisability of findings from single studies and focus on interventions across a broad range of geographical locations, settings and populations, types of implementations and outcomes. We will also address (when possible) the identified gaps in literature regarding metaanalysis in conflict‐affected contexts. As such, we propose the following objectives: (1) The primary objective of this review is to identify, assess and synthesise evidence on the effect of gender specific and gender transformative interventions within the context of the four pillars of United Nations Security Council Resolution (UNSCR) 1325 on women's empowerment and gender equality in Fragile and Conflict Affected States/Situations (FCAS). The SR will facilitate the use of evidence in informing policy and practice decisions within the field of transition aid, particularly as it relates to gender focused programming. (2) Our second objective is to assess how these interventions contribute to inclusive and sustainable peace in conflict affected situations. We will compare the effectiveness of these different types of interventions through the lenses of their ecological level, types of impact on women's empowerment, local context of gender inequality and conflict. To achieve these objectives we aim to answer the following questions: (1) What are the impacts of gender transformative and specific interventions on women's empowerment and gender equality in FCAS? (2) What are the effects of these interventions on sustainable peace? (3) To what extent do effects vary by population group, ecological level and types of interventions? (4) What are contextual barriers to and facilitators of intervention effectiveness?

The International Initiative for Impact Evaluation (3ie) promotes evidence-informed equitable, inclusive and sustainable development. We support the generation and effective use of high-quality evidence to inform decision-making and improve the lives of people living in poverty in low-and middle-income countries. We provide guidance and support to produce, synthesise and quality assure evidence of what works, for whom, how, why and at what cost. 3ie systematic reviews3ie systematic reviews appraise and synthesise the available high-quality evidence on the effectiveness of social and economic development interventions in low-and middleincome countries. These reviews follow scientifically recognised review methods, and are peer-reviewed and quality assured according to internationally accepted standards. 3ie is providing leadership in demonstrating rigorous and innovative review methodologies, such as using theory-based approaches suited to inform policy and programming in the dynamic contexts and challenges of low-and middle-income countries.

BackgroundWomen’s empowerment interventions represent a key opportunity to improve nutrition-related outcomes. Still, cross-contextual evidence on the factors that cause poorer nutrition outcomes for women and girls and how women’s empowerment can improve nutrition outcomes is scant.The objective was to rapidly synthesise the available evidence regarding the impacts of interventions that attempt to empower women and/or girls to access, participate in and take control of components of the food system. MethodologyWe considered outcomes related to food security; food affordability and availability; dietary quality and adequacy; anthropometrics; iron, zinc, vitamin A, and iodine status; and measures of wellbeing. We also sought to understand factors affecting implementation and sustainability, including equity. We conducted a rapid evidence assessment, based on the systematic literature search of key academic databases and grey literature sources performed for the regular maintenance of the living Food System and Nutrition Evidence Gap Map. Impact evaluations and systematic reviews of impact evaluations that considered the women’s empowerment interventions in food systems and food security and nutrition outcomes were eligible for inclusion. We conducted an additional search for supplementary, contextual, qualitative data related to included studies. ConclusionOverall, women’s empowerment interventions improve nutrition-related outcomes, with the largest effects on food security and food affordability and availability. Diet quality and adequacy, anthropometrics, and well-being effects were smaller. Due to the limited number of included studies for anthropometric and well-being outcomes, these effects are inconclusive. Insights from the qualitative evidence suggest that women’s empowerment interventions best influenced nutritional outcomes when addressing characteristics of gender-transformative approaches, such as considering gender and social norms. Policy-makers should consider improving women’s social capital so they can better control and decide how to feed their families. Qualitative evidence suggests that multi-component interventions seem to be more sustainable than single-focus interventions, in particular combining a livelihoods component with behavioural change communication. Researchers should consider issues with inconsistent data and reporting, particularly relating to seasonal changes, social norms and time taken between rounds of data collection. Future studies on gender-transformative approaches should carefully considering contextual norms and avoiding stereotyping women into pre-decided roles which may perpetuate social norms.
