Daria Khaltourina

Daria Andreyevna Khaltourina (Russian: Дáрья Андрéевна Халтýрина; born 4 January 1978 in Chelyabinsk) is a Russian sociologist, anthropologist, demographer, and a public figure. She is the head of the Group of the Monitoring of Global and Regional Risks of the Russian Academy of Sciences, co-chairperson of the Russian Coalition for Alcohol Control, as well as the Russian Coalition for Tobacco Control. She is a laureate of the Russian Science Support Foundation Award in "The Best Economists of the Russian Academy of Sciences" nomination (2006).

In this field she has proposed one of the most convincing mathematical explanations for von Foerster's Doomsday Equation. In collaboration with her colleagues, Artemy Malkov and Andrey Korotayev, she has shown that till the 1970s the hyperbolic growth of the world population was accompanied by quadratic-hyperbolic growth of the world GDP, and developed a number of mathematical models describing both this phenomenon, and the World System withdrawal from the blow-up regime observed in the recent decades. The hyperbolic growth of the world population and quadratic-hyperbolic growth of the world GDP observed till the 1970s have been correlated by him and his colleagues to a non-linear second order positive feedback between the demographic growth and technological development that can be spelled out as follows: technological growth – increase in the carrying capacity of land for people – demographic growth – more people – more potential inventors – acceleration of technological growth – accelerating growth of the carrying capacity – the faster population growth – accelerating growth of the number of potential inventors – faster technological growth – hence, the faster growth of the Earth's carrying capacity for people, and so on.
