Strengthening democracy and freedom in backsliding contexts: mapping and synthesizing the evidence

In recent years, international observers such as the V-Dem Institute have highlighted an alarming crisis of democracy with a decline in competitive elections, political participation and public accountability. For the first time in two decades, the Institute’s 2023 Democracy Report found more closed autocracies than liberal democracies in the world.

15 years of 3ie: "We need an effectiveness culture," panelists say

Opening the expert panel which convened last week in Washington to mark 3ie's 15th birthday, Inter-American Development Bank President Ilan Goldfajn made a pitch that would be echoed throughout the morning.

Innovative study to measure gender norm foundations and change in rural Bangladesh

Gender norms or shared beliefs about what women and men ought to do in a particular social context determine how they interact with each other. A critical shift away from regressive gender norms is imperative to make progress toward gender equality. But these norms are considered particularly resistant to change and are often the reason behind limited impacts of development programs on gender equality and women’s empowerment.

New resilience Evidence Gap Map shows some key evidence, many gaps

Interventions that aim to improve resilience, either for households or communities, have become increasingly common in recent years. Yet there are big knowledge gaps regarding what works, as shown on 3ie's new evidence gap map on building resilient societies.

Mapping the evidence to understand what works for addressing root causes and drivers of irregular migration

Nearly every week, people lose their lives as they try to migrate for survival or in search of better opportunities. Even as recently as when this post was written, four boats sank during their journey from Tunisia to Italy. Since 2014, the International Organization for Migration (IOM) estimates, 53,792 people have died or gone missing while migrating internationally using irregular pathways.

Mapping the big picture: Are WASH achievements linked to higher-level development goals?

Effective water, sanitation and hygiene (WASH) programs can demonstrably improve sanitation, health, and water access. But, does WASH programming also contribute to additional development goals like education, economic growth, or women’s empowerment?

New evidence on humanitarian aid: Cash transfers improve outcomes for Venezuelan migrants in Colombia

A recently-completed impact evaluation conducted by 3ie in the context of the Venezuelan crisis contributes to filling this void. Our study shows that a multipurpose cash transfer program for Venezuelan migrants in Colombia yielded positive effects on migrants' incomes, food security, savings, and labor force participation rates.

Insights from the Development Evidence Portal: Where is the evidence (like, on a map)?

As we mark 3ie’s 15 years, it’s an opportune time to take stock of the “state of the evidence”, using one of our major contributions to the field of evidence use: the Development Evidence Portal (DEP). The Portal makes evidence about the effectiveness of development interventions accessible to a large constituency of evidence users, funders, and decision-makers across the globe.

Wrapping up USAID's Evidence Month: Panelists discuss pathways to build an evidence culture

As we've discussed on this blog before, the development community has made tremendous strides in producing and using rigorous evidence, and it also still has a long way to go to build a strong evidence culture. The closing plenary for USAID's Agency Learning and Evidence Month on 27 April reflected recent years' progress and the remaining challenges.
