Аннотация
Food security which refers to the satisfaction of individuals’ dietary needs and accessibility to food is a vital component of the national security of any country. There are many ways how to affect food security thus resulting in the change of living conditions of all individuals. In our work we study a food power of each country from the perspective of produce trade. The trade relations between countries are represented as a network, where vertices are countries or territories and edges are export/import flows. As flows of products between states are heterogeneous we cannot consider different types of products in a single network, this is why we consider 10 networks, where each network refers to one particular group of substitute goods (cereals, meat, etc.). To detect key participants affecting food security we calculate both classical centrality measures and short- and long-range interaction indices which consider individual attributes of countries (food production and consumption levels, etc.) and complex interactions between them. The analysis is based on annual reports of export and import data provided by the World Bank. The influence of countries through each homogeneous group of products was aggregated into a single food power index. We also studied how the influence of countries is changed over the years.
