The West Africa Region has been one of the slowest in reducing its many burdens of malnutrition. The World Health Assembly’s (WHA) 2025 nutrition targets were developed to track countries’ nutritional situations, and measure progress in reducing malnutrition. These indicators are therefore essential to guide decision making. Understanding the regional and in-country dynamics are an essential first step to highlight gaps and trends in evidence in the region. A new study by Transform Nutrition West Africa identifies these trends and gaps in research that cover the WHA indicators across West Africa. These are potentially valuable insights for nutrition decision makers in the region. This map focused on Senegal will be updated annually and is to be used as a freely accessible resource for decision-makers at all levels.
