Evidence Action scales evidence-based and cost-effective programs to reduce the burden of poverty. 

Our organization was founded in 2013 to address a big gap in the fight against global poverty--many of the most promising interventions are either implemented at a very small scale, or not at all. We set out to address this gap by building programs that would scale evidence-based and cost-effective interventions, leading to significant improvements in quality of life for hundreds of millions of people. 

Our model worked. In less than a decade, our two flagship programs, the Deworm the World Initiative and Dispensers for Safe Water, have grown to measurably impact over 280 million people each year. This success is achieved through the dedication and talent of our staff, the hard work of our partners, and the commitment of our supporters.

By 2024, we seek to double our impact. We are strengthening and expanding our existing programs, and working to identify a new generation of evidence-based and cost-effective interventions that we can scale to reach millions more. 

We currently operate three programs:

Dispensers for Safe Water 

Dispensers for Safe Water program delivers free and reliable access to safe water for 4 million people in rural Kenya, Uganda, and Malawi.
In rural parts of low-income countries, most water sources are untreated, meaning that water is not safe to drink directly from the source. Our uniquely-engineered chlorine dispensers are installed next to commonly-used water sources, enabling people to treat their water using a safe and pre-measured dose of chlorine. The chlorine stays active for 2-3 days, ensuring water doesn’t get recontaminated even when stored at home. Adding diluted chlorine to water is a WHO-endorsed approach to improving water quality. 
Dispensers for Safe Water is a cost-effective solution - just over $1.00 delivers safe water access to one person for an entire year. In 2019, our program averted over 380,000 cases of diarrhea among children, one of the main causes of childhood mortality in the countries where we operate.

Deworm the World Initiative

Deworm the World Initiative helps governments launch, scale, and sustain school-based deworming programs.

Over 868 million children globally are at risk of contracting parasitic worm infections. If left untreated, infections can lead to anemia, malnourishment, and impaired mental and physical development—ultimately affecting children’s educational outcomes and income as adults.Our program brings free treatment to children at their schools instead of placing the burden on the families to obtain it. We partner with governments to regularly treat all at-risk children in places where at least 20% are infected with worms, as recommended by the World Health Organization.  

Rigorous research shows that deworming leads to significant improvements to children’s health, education, and long-term wellbeing. In 2019, we helped governments treat over 280 million children in India, Kenya, Nigeria, Ethiopia, and Pakistan for less than US 50 cents per treatment.

Accelerator:  
 
Evidence Action Accelerator is our engine for new program development that selects, optimizes, and scales interventions with the highest potential to measurably improve the lives of millions of people in the world’s poorest places.  

Each intervention considered by the Accelerator must undergo a multi-stage process of program development, taking it from an evidence-based concept to a fully-developed solution that can be replicated in multiple geographies. We look for three critical aspects during the assessment process: rigorous evidence, cost-effectiveness, and potential for scale. 

We are currently accelerating two promising health solutions: working with the Liberian government to detect and treat maternal syphilis, with the aim of preventing thousands of child deaths and disabilities each year; and supporting the Indian government to improve the distribution of iron and folic acid supplementation to millions of children and adolescents —treating iron deficiency anemia, one of the main causes of disability in the country.
