Evidence shows that food insecurity, poverty and geographic disparities in developing countries are strongly correlated. The proposed methodology aims to capture the spatial dimension of food insecurity, shed light on how food systems work and understand what determines food security and nutrition levels in a given space and time. It proposes an analytical framework to conduct a comprehensive, participatory and integrated assessment of Food Security and Nutrition Systems (FSNS) patterns focusing on three broad categories of exchanges determining food landscapes (i.e., mobility of people, goods, and services) and on the interplay between the actors involved in these exchanges, including their (in)formal institutions and networks.




Approximately 3 billion people across the globe have low-quality diets according to the Global Panel on Agriculture and Food Systems for Nutrition (2016). FAO estimates that more than 800 million people suffer from chronic hunger (SOFI, 2017). World Health Organization (WHO), UNICEF, and the World Bank (2013) report that 161 million children under the age of five are stunted, and that 3.4 million people die each year due to overweight and obesity. The cost of malnutrition is estimated by FAO at about 3.5 trillion USD per year (FAO, 2013), that is slightly less than the total value of food and agribusiness in the world, estimated by McKinsey at 5 trillion USD. Moreover, the incidence of overweight and obesity is growing in every region. The situation is set to worsen dramatically over the next 20 years if powerful drivers of change such as population growth, climate change and urbanization, all converging on food systems, are not adequately addressed.
