Personal subsidiary plots are one of the main categories of producers in the Russian food security system. An analysis of food independence is presented in the article. The article assesses the contribution of private farms to ensuring food security in Russia. This category of producers faces agricultural risk events. Farms are experiencing a shortage of financial resources to compensate for damage. Risks can be neutralized using agricultural insurance mechanisms with government support. The mechanism for assessing regions for the introduction of agricultural insurance with state assistance is discussed in the article. It is based on ranking the regions of operation of private farms. Ranking is carried out according to the degree of priority of ensuring food security and supporting producers in risky farming areas in the regions. The use of this mechanism will allow directing state support for private farms to the most significant and strategically important regions.
