15 years after "Will we ever learn?": Well, did we?

Fifteen years ago, the Evaluation Gap Working Group published a report noting the absence of solid evidence on the effectiveness of development programming. This report, and the intellectual community behind it, drove a wave of work on impact evaluations in the development sector. So, did we learn?

Evidence impact: Increasing immunization rates by engaging community leaders

In Nigeria, as in much of the developing world, many children never receive their full set of recommended immunizations. Even among children who receive some vaccinations, not all return for subsequent doses or later shots. In 2019, only 57 percent of infants in Nigeria completed their three-shot course of the DTP (diphtheria, tetanus, pertussis) vaccine.

Evidence Dialogues: Implementation research is key to understanding why nutrition interventions work – or don't

In Thursday's 3ie Evidence Dialogues webinar, nutrition experts shared the reasons implementation research is so important in the field, as well as some examples of key takeaways from already-completed studies.

Evidence impact: Claiming the influence of studies with confidence

In a previous blog, we described our definition of 'evidence impact.' Now, given how messy the decision-making process can be in the real world, how can we be sure that a study and its findings made an impact?

Service d'assistance WACIE: Un nouveau dispositif pour accompagner l’usage des données probantes en Afrique de l'Ouest

Les lacunes dans l'expérience d'évaluation sont criantes dans les pays membres du programme de renforcement des capacités et évaluation d'impact en Afrique de l'Ouest (WACIE), comme en témoigne l'étude exploratoire du programme. En conséquence, l'utilisation des données probantes dans l'élaboration des politiques est limitée. Mais l'obstacle principal à cette utilisation est la capacité, pas l'intérêt. L’étude exploratoire a révélé un intérêt presque universel chez les décideurs politiques et professionnels de l'évaluation pour le l’accompagnement et le renforcement des capacités en la matière.

WACIE Helpdesk: A new source of support for evidence-informed decision-making in West Africa

In the countries where the West Africa Capacity-building and Impact Evaluation (WACIE) program works, the gaps in evaluation experience are stark, as the program's scoping study found. Accordingly, the use of evidence in policymaking is limited. But the barrier is capacity, not interest – the same study found that the desire among policymakers and evaluation professionals for support and capacity building was nearly-universal.

Working side-by-side across the COVID divide

At 3ie, with our biggest offices in India and the United States, we're currently treading on both sides of a stark, life-and-death divide. On our regular video calls, our faces are intermingled on the screen. But right now, when we step away, we walk into different worlds.

All eyes on immunization: what do we know about effective vaccination campaigns?

With COVID still raging across the world, the topic of immunization is receiving more attention than it has in decades. Today, the world is waiting to see if immunizations will help turn the corner and end the biggest health and humanitarian crisis in a generation. Given this, policymakers and implementers need to know what works to increase immunization rates, for whom, and at what cost.

Evidence Impact: Residents use drones and apps to protect the Ecuadorian Amazon

In the Ecuadorian Amazon, a highly biodiverse tropical rainforest, more than 3,000 active oil wells pose threats to both the people and wildlife who live there. In addition to accidental oil spills, these wells' operators sometimes intentionally discharge toxic byproducts of the oil production process into streams and rivers.

Evidence Dialogue: For development institutions, learning requires more than collecting data

The world's development institutions collect lots of data – but do they learn from it? Perhaps not as much as they should. Between the challenges of quick timelines, rigid systems, and disconnects between implementers and evaluators, development agencies do not always walk the talk of evidence-informed decision-making, 3ie's expert panel agreed.
