A growing body of evidence indicates that agricultural development programs can potentially improve production diversity and diet quality of poor rural households; however, less is known about which aspects of program design are effective in diverse contexts and feasible to implement at scale. We address this issue through an evaluation of the Agriculture, Gender, and Nutrition Linkages (ANGeL) project. ANGeL is a randomized controlled trial testing what combination of trainings focused on agricultural production, nutrition behavior change communication, and gender sensitization were most effective in improving production diversity and diet quality among rural farm households in Bangladesh. We find that trainings focused on agriculture improved production diversity in terms of greater production of fruits and vegetables grown on the homestead, eggs, dairy, and fish; adding trainings on nutrition and gender did not significantly change these impacts. Trainings focused on both agriculture and nutrition showed the largest impacts on diet quality, with evidence indicating that households in this arm also significantly increased consumption out of homestead production for fruits and vegetables, eggs, dairy, and fish. Findings indicate that agricultural training that promotes production of diverse, high-value, nutrient-rich foods can increase production diversity, and this can improve diet quality, but diet quality impacts are larger when agricultural training is combined with nutrition training. Relative to treatments combining agriculture and nutrition training, we find no significant impact of adding the gender sensitization on our measures of production diversity or diet quality.

The relationships between agricultural diversity, dietary diversity, and gender norms are complex and multi-dimensional. To better understand these links, and how to most effectively promote nutrition- and gender-sensitive agriculture in Bangladesh, the International Food Policy Research Institute (IFPRI) designed the Agriculture, Nutrition, and Gender Linkages (ANGeL) pilot project, implemented by the Ministry of Agriculture, Government of the People’s Republic of Bangladesh. ANGeL aimed to identify actions and investments in agriculture that will help increase farm household income, improve nutrition, and empower women. Using rigorous research, namely, a randomized controlled trial design, IFPRI assessed impacts of the ANGeL project interventions on various outcomes. Over the 17-month implementation period, with no inputs provided to participating farm households besides knowledge from trainings, ANGeL generated useful lessons on strengthening the agriculture-nutrition-gender nexus in the country. Both men and women benefited from agricultural trainings, yet women learned more from the same trainings. Crop diversity increased substantially in homestead gardens, mainly due to ANGeL’s emphasis on homestead food production from nutritious crops. Farmers also adopted improved production practices. We consistently found that women were more likely to apply knowledge gained from agricultural production trainings to adopt various types of improved agriculture production practices, such as pest disease and control, seed production and care, and use of quality fertilizer. Similarly, improvements in nutrition knowledge were far greater for women and when trainings were combined. These improvements in knowledge had impacts on nutrition outcomes, with increases in household diet quality and child dietary diversity over the project period. The strongest improvements in empowerment came when agriculture, nutrition, and gender sensitization trainings were combined. ANGeL’s household approach empowered women and men in unique ways: while women became more empowered in asset ownership and income decisions, men became more empowered in production and income decisions in select interventions. Attitudes related to gender of both women and men also improved, with more women recognizing that they make important contributions to their communities. ANGeL is the first ministry-led initiative that uses a rigorous impact evaluation to develop an evidence base to design and implement a national program. The ANGeL project is a significant step towards filling critical knowledge and action gaps in the country on promoting nutrition-and gender-sensitive agriculture.

A growing number of governments, donor agencies, and development organizations are committed to supporting nutrition-sensitive agriculture (NSA) to achieve their development goals. Although consensus exists on pathways through which agriculture may influence nutrition-related outcomes, empirical evidence on agriculture’s contribution to nutrition and how it can be enhanced is still weak. This paper reviews recent empirical evidence (since 2014), including findings from impact evaluations of a variety of NSA programs using experimental designs as well as observational studies that document linkages between agriculture, women’s empowerment, and nutrition. It summarizes existing knowledge regarding not only impacts but also pathways, mechanisms, and contextual factors that affect where and how agriculture may improve nutrition outcomes. The paper concludes with reflections on implications for agricultural programs, policies, and investments, and highlights future research priorities.

Nutrition-sensitive agricultural diversification continues to receive interest among developing country stakeholders as a viable option for achieving dual goals of poverty reduction and food/nutrition security improvements. Assessing the effectiveness of this strategy is also essential in countries like Tajikistan. We attempt to enrich the evidence base in this regard. We assess the linkages between household-level agricultural diversification and dietary diversity (both household- and individual-levels) using unique panel samples of households and individual women of reproductive ages in the Khatlon province. Using difference-in-difference propensity-score methods and panel fixed-effects instrumental variable regressions, we show that higher agricultural diversification together with greater overall production per worker and land at the household level leads to higher dietary diversity, particularly in areas with poor food market access. Typology analyses and crop-specific analyses suggest that vegetables, fruits, legumes/nuts/seeds, dairy products and eggs are particularly important commodities for which a farmer’s own production contributes to dietary diversity improvement. Furthermore, decomposition exercises within the subsistence farming framework suggest that nutritional returns and costs of agricultural diversification vary across households, and expected nutritional returns may be partly driving the adoption of agricultural diversification. In other words, households’ decisions to diversify agriculture may be partly driven by potential nutritional benefits associated with enhanced direct on-farm access to diverse food items rather than farm income growth alone. Our findings underscore the importance of supporting household farm diversification in Tajikistan to support improved nutrition intake, especially among those living in remote areas. In a low-income setting with limited local employment opportunities that is vulnerable to a wide range of external shocks, this will likely continue to be one of the most straightforward and realistic paths to improving household’s nutrition resilience.

We use a randomized controlled trial in rural Bangladesh to compare two models of delivering nutrition content jointly to husbands and wives: deploying female nutrition workers versus mostly male agriculture extension workers. Both approaches increased nutrition knowledge of men and women, household and individual diet quality, and women’s empowerment. Intervention effects on agriculture and nutrition knowledge, agricultural production diversity, dietary diversity, women’s empowerment, and gender parity do not significantly differ between models where nutrition workers versus agriculture extension workers provide the training. The exception is in an attitudes score, where results indicate same-sex agents may affect scores differently than opposite-sex agents. Our results suggest opposite-sex agents may not necessarily be less effective in providing training. In South Asia, where agricultural extension systems and the pipeline to those systems are male-dominated, training men to deliver nutrition messages may offer a temporary solution to the shortage of female extension workers and offer opportunities to scale promote nutrition-sensitive agriculture.
