According to many experts, the observed changes in the global climate are caused primarily by natural patterns, and the influence of anthropogenic impacts, including the growth of greenhouse gas emissions, only slightly increases them. Nevertheless, the desire to reduce emissions of these gases has become an important environmental and political task, included in many strategic documents, and a significant component of Russia’s environmental policy. Therefore, the development and testing of various methods and mechanisms for stimulating the reduction of greenhouse gas emissions, in particular in the agro-industrial complex, is very relevant. Statistics convincingly show that greenhouse gas emissions, at a certain level of technological development, are proportional to the population. Over the past 100 years, the population of the Earth has grown 4 times - from about 2 billion in 1923 to 8 billion in 2023. During this time, greenhouse gas emissions have increased about 12 times, and the average temperature of the planet has increased by 2,3 degrees. The sharp global warming, coupled with the intensification of the struggle for scarce natural resources and the growth of wealth inequality, poses a very real threat to the existence of humanity. It can be prevented by the emerging trend of a decrease in the total global fertility rate to 2,2 children per woman of childbearing age. This may soon lead to a decrease in the planet’s population. This article proposes methods for managing the natural decline in population by region of the Earth. At the same time, methods for adapting the Russian agro-industrial complex to climate change and stimulating the reduction of greenhouse gas emissions by agricultural enterprises remain relevant.
