According to the main modern world civilizations - European, Orthodox, Chinese, Japanese, Indian, Islamic, African and Latin American - forecast calculations of the population size, fuel and energy resources needs, and availability of agricultural land and fresh water until 2100 were carried out. Based on calculations, the main scenarios for the development of Eastern civilizations and world development scenarios are determined. Key words: long-term forecast of world development, population size, natural resources, modern civilizations, development scenarios. METHODOLOGY FOR ANALYZING LONG-TERM PROSPECTS FOR GLOBAL DEVELOPMENT A.V. Akimov's article " Long-term population forecast and prospects for civilizational interaction "(Vostok (Oriens), 2009, No. 4) considered the problems of long-term growth of the world population and its provision with natural resources for life and successful catch-up development. It has been shown that the world's population can come to an equilibrium with the planet's resources as a result of a demographic transition that ultimately causes a natural population decline. In addition, it is determined that in the XXI century, a significant strain on the economy and the Earth's resource system will be required to ensure demographic transition and catch-up development. This raises the question of how world development will proceed in the twenty-first century, what threats may arise, what conflicts will become significantly acute, and what are the prospects for world development during this transition period. The solution to this problem proposed in this article includes three components, the first of which is the calculation of the population size. page 5population and natural resource needs, which should ensure economic growth that promotes socio-economic development, which can lead to a demographic transition. Related tasks here are the study of growth limits (Meadows, Randers, Meadows, 2012). The second component is the forecast for modern ... Read more
