The problem: scaling impactful interventions

In order to tackle extreme poverty at the level it exists, how do we bridge the gap between identifying evidence-based, cost-effective interventions that work and successfully scaling them up to improve the lives of millions?

The solution: expertise

Evidence Action’s mission is to be a world leader in scaling evidence-based and cost-effective programs to reduce the burden of poverty. Evidence Action works to identify and scale interventions in Africa and Asia, filling the gap between promising research and achieving measurable impact.

Evidence Action was incubated by Innovations for Poverty Action (IPA), a highly respected poverty research network. (IPA is another of The Life You Can Save’s recommended organizations).

How Evidence Action works

Evidence Action operates three initiatives: Dispensers for Safe Water, Deworm the World Initiative, and Evidence Action’s Accelerator.

Dispensers for Safe Water

Every year, over 829,000 people die from diarrhea caused by unsafe drinking water, sanitation, and hand hygiene — and 297,000 of those deaths being children under five. [1] Dispensers for Safe Water ensures safe drinking water in rural communities in Kenya, Uganda, and Malawi through a three-part approach:

  1. Installing chlorine dispensers directly at local water sources — a proven, low-cost water treatment solution
  2. Working with local community promoters who market, maintain, and refill the dispensers
  3. Overseeing a locally staffed delivery and repair supply chain

Dispensers for Safe Water’s focus on behavioral change yields chlorine adoption rates that are five times higher than other water treatment solutions, and are sustained over time. [2]

Deworm the World Initiative

There are more than 868 million children at risk for parasitic worms worldwide. [3] These worms interfere with nutrient absorption and cause malnourishment, anemia, and impaired mental and physical development; they also prevent children from attending school, which impacts their success in life and ultimately harms developing economies. Those who remain persistently infected are 13% less likely to be literate. Deworming has very high social returns, with conservative benefit-cost ratio estimates ranging from 24:7 to 41:6. [4]

The Deworm the World Initiative works with governments to implement large-scale school-based deworming programs, currently supporting treatment of an estimated 280 million children annually. Deworm the World’s work has helped contribute to significant declines in worm prevalence in Kenya, and emerging evidence from India indicates that success in reducing prevalence is being achieved there as well. GiveWell named the program a top charity for the sixth time in 2018. [5]

Evidence Action’s Accelerator

Evidence Action’s Accelerator drives new program development. They test and refine delivery models of high-potential, cost-effective interventions with the goal of rapid scale and impact similar to their existing flagships. In 2019, Accelerator replaced Evidence Action Beta, maintaining an emphasis on robust evidence, cost-effectiveness, and impact at scale while prioritizing ready-to-implement interventions that leverage Evidence Action’s capabilities in scaled delivery. The Accelerator focuses on “ready to scale” programs within health and nutrition, with the goal of building the next generation of Evidence Action programs. [6]

What makes Evidence Action so effective


Broad reach and potential for scale

Dispensers for Safe Water currently provides 4 million people access to clean water, while the Deworm the World Initiative has scaled from treating 160 million children in 2015 to over 280 million children in 2018. [7] [8]

Cost-effectiveness

Dispensers for Safe Water’s current cost is US$1.28 per person per year, while deworming programs supported by Deworm the World cost on average less than US$0.50 per treatment – and in some geographies, such as India, the average cost is less than US$0.10 per treatment. [9]

Proven adoption rates

In areas where Dispensers for Safe Water works, use rates for chlorine have been extremely robust, ranging from over 50% to an astounding 100% in areas in Malawi. This is unheard of in the world of water and sanitation for point-of-collection products.

Compounding impact

A randomized controlled trial of deworming in Kenya found school-based deworming reduced school absenteeism by 25%, increased hours worked as adults by 17%, and increased future wage earnings by 23%. [10] [11] [12] [13]

Evidence Action’s accountability and sustainability

Evidence Action is a model of non-profit transparency. The organization makes its documents publicly available and publishes its reports and data. Notably, when programs prove to not be effective, Evidence Action recognizes and shares outcomes, and alters its programs accordingly. One such example was No Lean Season, which received acclaim and support after initial promising results. In its dedication to ongoing proof and accountability, Evidence Action continued to pressure-test the program for scalable robustness, and when the evidence proved to be disappointing, the organization publicized the new findings and halted funding. Subsequently, operational challenges combined with the disappointing evidence led to the closure of No Lean Season. As Vox observed, “We’d benefit enormously from a nonprofit sector in which every charity was as careful and honest as Evidence Action.”

Recognition for Evidence Action

Evidence Action’s Deworm the World and Dispensers for Safe Water Initiatives are the direct result of the work of Michael Kremer and Esther Duflo, two of the winners of the 2019 Nobel Prize in Economic Sciences. [14] Both projects are recommended by rigorous evaluator GiveWell, and The Jameel Poverty Action Lab lists school-based deworming as a “best buy” in terms of education and health. [15] [16]

In July 2018, GiveWell awarded a Good Ventures-funded incubation grant of $5.1 million to Evidence Action Beta “to create a program dedicated to developing potential GiveWell top charities by prototyping, testing, and scaling programs which have the potential to be highly impactful and cost-effective.” Evidence Action’s Accelerator will take forward this work, and is currently using GiveWell funding to support the Government of India’s iron and folic acid supplementation program.

Frequently Asked Questions

How will Evidence Action use my donation?

Evidence Action will direct donations to where they are most needed. Unrestricted donations enable the organisation to determine the area of greatest need and investment, and direct those flexible funds accordingly.

Funds they direct to Dispensers for Safe Water will help enable the program to provide reliable, sustained safe water service in rural communities by financing the capital costs of installing the hardware and covering ongoing maintenance services.

Funds Evidence Action directs to Deworm the World will support their work to partner with governments and implement large-scale school-based deworming programs.

Funds which are used for Evidence Action’s Accelerator will help build the next generation of evidence-based, cost-effective interventions.

Can I specify which program receives my donation?

Evidence Action prefers donations not be restricted to a specific intervention so that they can direct funding wherever the need is greatest. For example, a particular program may be undertaking expansion due to new opportunities, or have a critical funding need that unrestricted funds can be used to fill. Donations made to Evidence Action via The Life You Can Save are unrestricted.

How much confidence do you have in Evidence Action’s Deworm the World Initiative, given the recent debate over the benefits of deworming?

In July of 2015, a re-analysis of an influential study on deworming was released, kicking off an ongoing debate about the benefits of mass deworming. Generally speaking, there appears to be a division between the health community, which is more skeptical about the benefits of mass deworming, and the development economics community, which is more enthusiastic. Each community has its own standard analytical methodology, and these different methodologies lead to different interpretations of the data. [17] [18] [19]

Evidence Action still believes that preventative school-based treatment is the cheapest and most cost-effective way of treating parasitic worms in children. Charity evaluator GiveWell also continues to recommend Deworm the World.

We think the deworming debate emphasizes the need for applying rigorous scientific standards and sharing data when evaluating interventions to allow us to refine and update our collective understanding. Efforts such as Evidence Action Accelerator, which assesses whether promising interventions are suitable for mass scale or not, are critical in this regard.

Why does The Life You Can Save recommend Evidence Action?

We recommend Evidence Action because GiveWell, one of our charity evaluators, has named their Deworm the World program a top charity, and their Dispensers for Safe Water a standout charity.
