Groundbreaking studies now part of 3ie's Food Systems and Nutrition Evidence Gap Map

In June 2022, a high-level expert group from the European Commission called for independent and up-to-date reports on the scientific evidence about food systems transformation. We certainly agree this work is essential – that’s why we’ve been producing such reports since 2020 as part of 3ie’s living Food Systems and Nutrition Evidence Gap Map (EGM). In our latest update, we add groundbreaking studies to the map, including one on sugar-sweetened beverage taxes.

Evidence Dialogues: Building connections between researchers and policymakers to eliminate hunger

Sustainable Development Goal 2 – eliminating hunger – is breathtaking in both its simplicity and its scope. We all know how to avoid hunger in our own lives, but on a global scale, the task brings together a dizzying array of potential policies: agricultural support, cash transfers, school lunches, or taxes on sugary sodas, to name just a handful.

Mapping evidence gaps in interventions improving food security in humanitarian settings

Natural and human-induced catastrophic events are pushing humanity to the brink. The compounding and cascading effects of armed conflicts, irreversible climate change, and the global outbreak of COVID-19 are devastating economies and driving more households into poverty. Today, nearly 193 million people are living in a food crisis (2022 Global Report on Food Crises) while 49 million are experiencing alarming levels of hunger (Hunger Hotspots report June 2022).

Reconciling theory and practice: An adapted community engagement framework for child immunization

In our newly-released systematic review on routine child immunization, we developed a community engagement typology to bridge this gap between theory and practice. We came across three ways communities had been engaged: engagement in the design of the intervention, engagement in the implementation of the intervention, or engagement embedded as a component in the intervention.

Mapping evidence to strengthen impact on resilience and food security

As per current estimates, almost 765 million people are affected by food insecurity worldwide. Chronic vulnerability, hunger, and water insecurity have been compounded by climate change, humanitarian crises, and COVID-induced shocks and pressures. USAID, through the Bureau for Resilience and Food Security (RFS), works through dedicated centers to improve program impacts on these critical issues and accelerate the progress on building resilient communities and countries.

Evidence Dialogues: How community engagement interventions can increase routine immunization

Although the COVID-19 pandemic drew plenty of attention to the need for one specific vaccine, the disruptions it caused also exacerbated existing challenges in ensuring all the world's children receive their shots.

Using mixed methods to strengthen process and impact evaluation

As necessary as conventional quantitative methods might be, the importance of adopting a mixed-methods approach in order to understand and answer complex development questions cannot be overemphasized. This blog is the second of a two-part series by 3ie Senior Research Fellow Michael Bamberger in which he offers detailed guidance on how to design, implement and utilize mixed-methods evaluations.

Three ways theories of change are helping evaluate a complex initiative to improve waste pickers’ lives

Urban waste pickers face several intertwined challenges such as low incomes, limited education, poor health, social marginalization, and domestic violence. In Bengaluru, India, 3ie is currently evaluating an initiative called Saamuhika Shakti, which adopts an innovative ‘Collective Impact’ approach to improving the lives of informal waste pickers. The initiative, just like the problems it looks to address, is complex.

Importance of mixed-methods approaches in development research and evaluation

As necessary as conventional quantitative methods might be, the importance of adopting a mixed-methods approach in order to understand and answer complex development questions cannot be overemphasized. In the first blog of this two-part series, 3ie Senior Research Fellow Michael Bamberger explains how an integrated mixed-methods approach goes much beyond incorporating just a few tools from both the quantitative and qualitative traditions and why that is more effective for addressing real-world problems.

In the fast-growing field of food systems impact evaluations, a shift toward evaluating consumer behaviour

As we've noted before on this blog, the world faces a critical need to revamp its food systems to provide healthy diets for a growing global population within the planetary boundaries. Making these changes means policymakers need to know what interventions work, for whom, and at what cost – and the state of knowledge about that question is changing rapidly.
