The article discusses analytical aspects of the economic approach to the problem of food security. Food security measurement and indicators are analysed and world food security situation is assessed with reference to theoretical and empirical literature, and principles of environmental economics and sustainable development. The first part of this article discusses food security measurement and indicators, and how they are estimated at the national level. There are five methods that can be used to assess food insecurity: United Nations Food and Agriculture Organization method, household expenditure surveys, dietary intake assessment, anthropometry and experience-based food insecurity scales. Food insecurity factors can be grouped in four clusters: 1) the socio-economic and political environment; 2) food economy; 3) care practices; 4) health and sanitation. The second part of this article analyzes the current food security situation in the world. W ith reference to United Nations Food and Agriculture Organization data it can be stated that the increase of hunger in the world is not a result of poor crop harvest, but rather of insufficient investment in agriculture, high local food prices, lower income and higher unemployment do to economic slowdown witch followed on the heals of food price crises. Rising international cereal prices and drop in national crop production have increased food prices in many countries of the world. The biggest increase in food prices were in developing countries. The third part of this article discusses the causes of world food price crisis. Many factors contributed to resent food security situation and food price rise. Long term trends in agricultural production, population growth, economic growth in developing countries, oil prices have slowed food production growth and strengthened demand.[...].

The article discusses the economic approach to the problem of food security. Food security concept and its impact on economic growth is analysed theoretically with reference to theoretical and empirical literature, and principles of environmental economics and sustainable development. The first part of this article considers the concept of food security. Now food security is defined as “ensuring that all people at all times have both physical and economic access to the basic food that they need”. This concept was introduced, when it was realized that adequate food availability at the national level did not automatically translate into food security at the household level. A. Sen’s theory on food entitlement, witch was developed to household livelihood approach, had a considerable influence in this change in thinking. Poverty and people’s vulnerability were seen as central to understanding food insecurity. By the mid-1990s food security definition had been broadened to incorporate food safety and nutritional balance. Food security concept involves these dimensions of food security: a) availability of food, b) access to food, c) food utilization, d) stability. First of all, it is necessary that there would be enough food available at the national level. Second, households must also have the necessary resources to acquire that food. Moreover, to achieve nutritional security people need adequate care and a healthy living environment. Finally, they should not risk losing access to food as a consequence of an economic or climatic crisis, or cyclical events. The second part of this article analyzes the impact of nutrition on economic growth. The positive effect of economic growth on nutrition has been amply demonstrated in both the theoretical and empirical literature.[...].
