The bullet point of Sustainable Development Goals (SDGs) 2030 is improving of countries food security through decreasing of hungry level and providing equal conditions for food to everyone. Besides, according to the findings the issues with hungry index could be solved through developing the agricultural sector corresponding of SDGs principals. The findings showed that the agricultural sector is start point of decreasing the hungry. The authors proved the type of the political regime had impact on the efficiency of achieving of SDGs and countries’ food security. The hypothesis of investigation was checking the relationship between political profile of the countries and level of sustainable development of the agricultural sector (ASI). The assessment of the relationship between average level of ASI and countries' democratic profile (democracy level of public relations) for 28 countries of Post-Soviet bloc proved the non-existence of differences between countries with authoritarian and transitional regimes opposed to other political regimes (imperfect and full democracy). The authors allocated three segments of countries: authoritarian and transitional regimes, imperfect democracy and full-fledged democracy. The findings proved the hypothesis that democracy level had a statistically significant impact on the average level of ASI. Using the bivariate and multivariate models the authors empirically proved that the democracy level increase by 1-point leads to the increase of the target index by 0.087 points for countries with authoritarian and transitional regimes (to which Ukraine belongs). Thus, the transition to a more democratic model of the political regime will partially offset the threats to food security.
