In Uganda, researchers conducted an impact evaluation of a faith-based couples counseling program called Becoming One. To attract a wide audience, Becoming One does not directly address violence, focusing instead on improving couples' relationships and shifting decision-making power.

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. Poor accountability may enable these negative behaviors.

As COVID-19 vaccination ramps up worldwide, understanding factors that may lead people in low- and middle-income countries (LMICs) to reject COVID-19 vaccination is of global concern, as lags in vaccination could facilitate global spread of virus variants. Researchers surveyed nearly 45,000 individuals in 10 LMICs, the United States, and Russia between June 2020 and January 2021on vaccine acceptance and trusted sources for vaccination advice.

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.
