In low-income countries, the unmet need for family planning contributes to high rates of maternal and infant mortality. In Kenya, there are nearly 500 maternal deaths per 100,000 live births and 37 infant deaths for every 1,000 live births. Despite the critical role of family planning service providers, many providers engage in negative behaviors that inhibit family planning use.

Over a billion people worldwide, most of whom live in sub-Saharan Africa, lack electricity, and mainly rely on kerosene lanterns for light. Recently, prices for solar lanterns have been dropping and they may help supply clean, affordable lighting and phone charging to those who are not connected to the electric grid. Yet little rigorous evidence is available on how this new technology is being adopted and used and how it affects people’s lives.

Deforestation is the second largest human source of carbon dioxide emissions. Mexico has a "payments for ecosystem services" (PES) program to provide economic incentives to landowners to minimize deforestation, but budget cuts have been recurring over the past years. Researchers are conducting a pilot study in one municipality of Selva Lacandona (Chiapas)  to find ways to improve the cost-effectiveness of the program.

Evidence suggests that socio-emotional skills, such as empathy and emotional regulation, play an important role in life outcomes, but little evidence exists on the impact of teaching these skills to very young children. In Colombia, researchers are evaluating how an early childhood curriculum with a socio-emotional focus impacts children’s competencies in empathy, inclusion, compassion, problem-solving, critical thinking, collaboration, emotional regulation, generosity, and advocating and car
