Reducing inequality in food access as a means to achieving the UN Sustainable Development Goals

The synergies between the whole set of SDGs highlights the relevance and central role the food system plays in achieving a better future for humanity and staying within planetary boundaries. Two main determinants of food access at the individual level are national food availability and household income. For this reason, the reduction of inequality among and within countries (SDG 10) will better enable achieving some of the most morally profound SDGs, ending poverty and eradicating hunger (SDGs 1 and 2). In this study we provide insights into within-country inequality in food access to enable future income-based estimation of environmental impacts across the globe. We used national income distribution by decile and national food availability estimates by major food group to estimate how food and nutrient access varied by income within countries over the past half century. We then used a scenario-based approach to study different future interactions of income growth, inequality trends and food productivity to estimate future food security and nutrition indicators. Our results show that future inequality plays a key role in pathways toward ending hunger and poverty.

Juan Diego is a PhD student at IRES working with Dr. Navin Ramankutty. His research is centered at the intersection between Food and Nutrition Security and the environmental impacts of different diets. Currently understanding how access to food is shaped by income/expenditure inequality, illustrating the disparities among and within countries in the past decades.

He holds a B.Sc in Biology and a B.Eng in Industrial Engineering for the Universidad de los Andes, Colombia. In the past, he worked with the Alexander von Humboldt Biological Research Institute and as a renewable energy consultant for Latin America
