Although the concept of self-sufficiency has been accepted both in developed and developing countries, alternated with periods of its rejections, the food crisis from 2007/08 and COVID-19 pandemic returned focus to the availability of countries to be self-sufficient in food production. Considering the concerns over ensuring food security in many countries, the main objective of this paper is to estimate the ability to fulfill the feed demand of the population in the eight countries of South-East Europe (SEE), which is in crisis conditions, such as pandemic especially important. In that context, the food self-sufficiency ratio (SSR) is calculated for total food production, as well as for different food groups. The next step in the methodological framework was to estimate the influence of different factors on the self-sufficiency ratio, as it depends on natural, financial, economic, and political factors. The results show that the SEE region expresses a high level of SSR in food, so it shows that the region is quite ready to respond to the challenges posed by the crisis. However, as the SEE region is a group of very different countries, regional cooperation should be strengthened as food production is considered.

Food loss and waste represents a global problem which is characteristic for all food supply chain sectors and all groups of countries. On average, every year one third of the total amount of food produced is lost or wasted, which indicates an extremely high level of inefficiency in the food supply chain. One of the key characteristics of food loss and waste is a wide range of ecological, economic and social implications, which is why this problem has become the subject of many national and global agendas. Although there is still no unique definition of the term food loss and waste and unique data collection methodology, many authors have researched this topic so far. Therefore, this paper's aim was to research the existing literature on the phenomenon of food loss and waste, as well as to observe trends of the amount of food loss and waste in the world and the EU. The results indicated that the differences between developed and developing countries have changed, and the amount of food waste in both groups of countries at the household level is now quite uniform. At the level of the EU, the household sector is also the largest generator of food waste.

Due to the environmental radicalization of European politics, which is reflected in the European Green Deal, Farm to Fork strategy, and new CAP 2023–2027, this paper aims to determine the impact of agri-environmental indicators on soil productivity based on the land productivity function model. The paper focuses on the Western Balkans countries, which are in the process of European integration and which, in the coming period, need to harmonize their agricultural policy with the CAP. First, the aggregate Cobb–Douglas production function has been used to create a land productivity function. Then, the sources of land productivity growth have been calculated, which can be particularly interesting in the context of agri-environmental indicators, such as fertilizer use and livestock density. The research results showed that land productivity is the most elastic concerning changes in the number of livestock units per hectare. Consequently, reducing livestock units had a markedly negative effect on productivity. In addition, the research results showed that using mineral fertilizers is a crucial source of growth in land productivity in these countries. These results imply that the creators of the agricultural policy must carefully assess the pace at which they will harmonize ecological and economic goals, especially if they take into account the current Ukraine crisis that can disrupt the food market.

Pig farming is the second most important branch of livestock production according to value of agricultural production, while pork meat is the most widely eaten meat in Serbia. As the one of the characteristics of pig market is cyclicality in the movement of production volumes and prices which can influence on the imbalance in supply and demand and in price fluctuations, the main aim of this paper was to analyse pork market in Serbia. Namely, in order to identify factors that influenced pork supply and demand, and to determine the presence of cyclical oscillations on pork market, pork market in Serbia was analyzed with supply and demand functions and with Cobweb model. The results indicated that factors which influenced on demand for pork were: personal consumption, retail price of pork and beef. On the other hand, on the supply side the most important factor was the price of pork. The results also indicated that in analyzed period in Serbia existed convergent type of Cobweb model.

As the pork supply chain was perceived through three level of chain: agricultural sector, processing and distribution sector, the main objective of this paper was the estimation of the vertical price transmission in the pork supply chain in the Republic of Serbia for period 2008-2015. The analysis of the price transmission was related on the presence of the asymmetry and was estimated with AECM model. The results indicated the presence of the negative asymmetry in the price transmission and one of the main causes of the presence of asymmetry was the abuse of the market power by processing sector, i.e. slaughtering industry.

Oil crops are very significant, both in the world and in Serbia. In terms of production, the three most important oil crops in Serbia are sunflower, soybean and rapeseed. Beside significant oil crops production, substantial quantities of oil are produced as well due to significant processing capacities in Serbia. Considering the fact that over the last few decades Serbian market has been characterized by integration with the international market and considering the actual market liberalization with the EU, CEFTA countries, Russia and others, this paper analyses production and export of oil crops with special emphasis on comparative advantages in the export of oil crops using the method of revealed comparative advantage. Also, the level of intra-industry trade is considered in relation to the international market, EU and CEFTA countries. The results indicate that oils have more significant comparative advantage on the international market, especially sunflower oil.
