Updating the rigorous evidence base on food security interventions in humanitarian settings

In 2022, 3ie published an Evidence Gap Map (EGM) of impact evaluations and systematic reviews of emergency food security interventions. Since then, the need for our easily accessible evidence repository has grown. Ongoing conflict, climate-induced disasters, and food insecurity have persisted and worsened.

El Niño’s grip on the Indo-Pacific: declining agricultural productivity and wider socio-economic consequences

As we approach mid-2025, it may be easy to forget last year’s record global weather anomalies associated with global warming and the recent El Niño event. This cyclical phenomenon occurs in the Pacific Ocean and significantly affects weather patterns, affecting millions of people living along the eastern and western Pacific coasts, as well as in countries across the Indian Ocean. El Niño and other climate drivers also cause more frequent extreme weather events such as droughts and floods.

Call for evidence on the effects of engaging the private sector in sustainable development

At a time when international development budgets are under pressure, involving the private sector in accelerating progress towards the UN's Sustainable Development Goals has become more pressing than ever. Rather than replacing public funding, private sector engagement serves as a strategic lever—especially in sectors where private investments can enhance sustainability and scalability. 

Evidence on climate, biodiversity and livelihoods highly concentrated thematically and geographically

Climate change alters or destroys ecosystems on land, oceans and coasts, leading species to extinction, forcing animals to migrate for survival and resulting in the emergence of non-native invasive species. This biodiversity loss can, in turn, exacerbate the climate crisis with greater carbon emissions from land-use change and deforestation.

Final update to living food systems E&GM: New studies address gender-transformative interventions and food loss outcomes

In our eighth and final scheduled update to 3ie’s living food systems evidence and gap map (E&GM), we add 307 new impact evaluations and eight new systematic reviews, bringing the total number of studies in the map to 3,218.

Recent and fast-growing evidence on sustainable energy interventions, but gaps remain

Progress towards achieving Sustainable Development Goal (SDG) 7 – to ensure universal access to energy and clean cooking, the adoption of renewables and an increase in energy efficiency – has been mixed. While electricity access has improved in select countries, clean cooking remains a prevalent issue for one in three people globally.

3ie's living Food Systems Evidence and Gap Map: Now expanded with social assistance and social insurance interventions

Our latest update of the living food systems evidence and gap map (E&GM) focuses on the addition of multiple new social assistance and social insurance intervention categories that we added to the map for the first time.

Assessing the effectiveness of food security and nutrition interventions on gender transformative outcomes

In 2023, 735 million individuals worldwide experienced hunger, and 258 million people across 58 countries and territories faced acute food insecurity at crisis or worse levels. With 60% of them comprising women, the gender gap in food insecurity continues to widen.

3ie's living Food Systems Evidence and Gap Map: Slow progress on evidence gaps, but little high-quality synthesis

In our most recent update to our living Evidence and Gap Map (E&GM) on Food Systems, we see the continuation of several trends: more evaluations of national and transnational programs; fewer evaluations of supplementation and fortification interventions; a shift toward quasi-experimental research; and a dearth of high-quality systematic reviews.

What works to reverse democratic backsliding? It’s complicated

Many countries have faced democratic backsliding or autocratization, especially in the past 30 years. With a staggering 72 percent of the world population living in autocracies (according to the V-Dem 2023 report), we need more evidence to better understand what works to support democracy and freedom in backsliding contexts to reverse this trend. To support this effort towards evidence-informed decision-making in democracy programming, 3ie has gathered existing findings in an evidence gap map and rapid evidence assessment (REA), with support from the UK government's Foreign, Commonwealth and Development Office (FCDO).
