Managing large-scale surveys: best practices for data collection preparation

Our team is evaluating India’s National Rural Livelihoods Mission (NRLM)—one of the world’s largest poverty alleviation programs. The study spans nine states of the country: Uttar Pradesh, Bihar, Rajasthan, Chhattisgarh, Maharashtra, Madhya Pradesh, West Bengal, Jharkhand, and Odisha. The survey, recently completed, covered over 25,000 households and 7,000 institutions, focusing on socio-economic indicators, institution-level data, and women’s empowerment. Managing such a vast operation required more than just structure and strategy.

Reaching SDG 5: Breaking down gender barriers to build lasting solutions

Progress to achieve gender equality by 2030 – the 5th Sustainable Development Goal – has stalled. The pandemic set back gains that had been made toward equality, and gender disparities remain entrenched in labor-force participation, unpaid care work, and access to essential services. Nearly one in five young women is married before the age of 18, and more than 245 million women and girls experience physical or sexual violence by an intimate partner each year (United Nations, 2023).

Mind the Gap: Cost evidence in development impact evaluations

Cost-effectiveness evidence can guide decision-making by showing which interventions offer the highest value for money, critical in an era of diminished resources for development. But, despite widespread acknowledgment of their importance, value for money analyses remain the exception rather than the rule. 

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.
