Importance of the territory climatic conditions as unpredictable dynamic changes problem that forms a threat to the development of the agricultural sector of the country was investigated. The problem comes from the fact that for food security of agricultural ecosystem it is rather vulnerable to change of climatic parameters, and agriculture belongs to branches which are especially sensitive to climatic changes impact. We analyzed long-term data figures for the period 1995 to 2014, which describe the temperature and moisture regime of Lubny (Poltava region). The main trends and patterns of their dynamics were established, the degree of deviation from the long-term norm was given. The author determined the relationship of the territorial climatic conditions changes and agricultural ecosystem performance and stability and also the potential consequences of the adverse effects. As a result, it was found that the expansion of the growing season crops, due to the increase in temperature and the average value of the classical heat supply plant index, may impair the stability of the agricultural ecosystem complex and reduce its performance. At the same time, one of the adapting agricultural production ways to climate change, which does not require any additional costs, is to optimize the placement of crops due to the harmonization of the production specialization ratio in accordance with the area conditions.
