Human civilization is developing in the regime with aggravation and maximum aggravation in 2025 — 2030. The development instability, the probability of not only unlikely - but also incredible events - global disasters, “Black Swans”, has drastically increased. There are tectonic changes happening in nature and society. In these conditions, more than ever, the importance of the Concept of Sustainable Development has increased not only as a theoretical and intellectual message to the development of humanity in total turbulence, but above all, to practical implementation of this Concept. Firstly, the changes taking place affected agriculture of the countries of the world and Russia, and especially its grain complex. From the perspective of system-synergistic, bioeconomic, cluster and global approaches, the definition to the “sustainable development of the grain complex” concept was developed, the structure of its potential development, a set of measures to increase the grain complex development stability in the format of agroforestry clusters system creation was proposed. The cluster system formation will be a radical tool to increase the stability, efficiency, and competitiveness of Russia's grain economy, weaken global climate change and prevent disasters.
