This report is a “shallow” investigation commissioned by Open Philanthropy. This primary focus of the report is to assess weather forecasting as a potential agricultural intervention in low- and lower-middle income countries and to examine the cost-effectiveness of different interventions.

In 2019, there were about 1.2 million deaths due to road injuries—about 90% of which occurred in low- and middle-income countries. In this report, researchers reviewed case studies of key time periods in China and Vietnam to better understand the relative impact of (philanthropically-funded) policy changes versus other factors.

This report is a broad overview of larval source management, including evidence for effectiveness, room for more funding, and coverage by existing implementers.

This report was commissioned by GiveWell and produced by Rethink Priorities from August to September 2023. The primary focus of the report is a landscape analysis to provide an overview of the major challenges, barriers, and improvement initiatives with regards to malaria-related data systems in sub-Saharan Africa. Our research involved reviewing the scientific and gray literature, and we spoke with three experts.

We examine data inputs and evidentiary strength of underlying selected disease burden estimates and identify promising interventions to improve disease burden data for fungal diseases, hepatitis, and malaria.

This report identifies the key actors and funding sources of, and the challenges facing, water programs in LMICs.

Our report aims to explore the impacts of maternal mortality on under-five mortality and household finances, with a focus on low-income countries.
