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...
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.
IntroductionBoth the World Health Organization and the Lancet Series on Adolescent nutrition recommend that governments adopt fiscal policies to combat diet-related non-communicable diseases (NCDs). However, rigorous, systematic evidence regarding the effects of these interventions is lacking.MethodsWe synthesize the available evidence regarding the impacts of taxes and subsidies that directly affect consumer prices on availability and accessibility of foods and beverages, purchasing behavior, diet quality, health and well-being outcomes as well as considerations for implementation, sustainability and equity.ResultsOur initial search returned 2,113 de-duplicated studies, and ultimately 24 impact evaluations and two systematic reviews met final eligibility criteria and represented unique evaluations. Our meta-analysis of these studies suggests that taxes may decrease purchases of taxed beverages (SMD = −0.14 [95% CI: −0.29 to −0.07], n = 15). Results should be interpreted cautiously due to considerable heterogeneity (Q(14) = 335.19, p = 0.01, τ^2=0.03, I2 = 95.82%).DiscussionThe evidence base is too limited to draw conclusions about the effects of taxes on beverages and calorie-dense foods on purchases, or on the effects of subsidies on purchasing or diet quality. Overall, the evidence base is inconclusive on whether fiscal policies can meaningfully influence the availability and accessibility of foods and beverages, diet quality, and health outcomes. Policymakers implementing fiscal policies should consider information campaigns on health benefits and health risks associated with certain food and beverage consumption. For taxes, exposure to health information may amplify signaling effects of taxes and reduce avoidance behaviors, such as cross-border shopping. Future evaluations should diversify data sources to better understand impacts on diet and health outcomes.
