Brouwer CGIAR Research Program on Agriculture for Nutrition and Health (A4NH) INTERNATIONAL FOOD POLICY RESEARCH INSTITUTE The International Food Policy Research Institute (IFPRI), a CGIAR Research Center established in 1975, provides research-based policy solutions to sustainably reduce poverty and end hunger and malnutrition. IFPRI’s strategic research aims to foster a climate-resilient and sustainable food supply; promote healthy diets and nutrition for all; build inclusive and efficient markets, trade systems, and food industries; transform agricultural and rural economies; and strengthen institutions and governance. Gender is integrated in all the Institute’s work. Partnerships, communications, capacity strengthening, and data and knowledge management are essential components to translate IFPRI’s research from action to impact. The Institute’s regional and country programs play a critical role in responding to demand for food policy research and in delivering holistic support for country-led development. IFPRI collaborates with partners around the world.

Nigeria, as with many parts of the world, is experiencing a multiple malnutrition burden, where undernutrition, including micronutrient deficiencies, exists alongside overweight, obesity, and associated diet-related non-communicable diseases. Recent data show that 37 percent of children under five years of age are stunted while 68 percent suffer some degree of anaemia. Overweight and obesity are also common among adults with prevalence rate of about 33 percent. The Nigerian government embraces sustainable food system approaches in its policy and programmes to address malnutrition problems in the country. Food systems approaches take a holistic understanding of all activities and processes involved in food production, processing, storage, transportation, trade, transformation, retail, and consumption. In this paper, we identify and discuss the types of research that can support the operationalization of food systems approaches to improving the quality of diets in Nigeria. Specifically, we structured a consultative workshop with key stakeholders, reviewed the literature, and applied food systems framework to the Nigerian context. The process enabled us to identify 39 research questions crucial to: understanding how changes in food systems can lead to healthier diets; identifying and testing entry points for improving availability and effective demand for healthier food; and creating at scale a supportive policy and market environment for achieving heathier and sustainable diets in Nigeria.
