WHAT A PHYSICIST CAN SAY ABOUT GLOBAL POPULATION GROWTH Sergey P. Kapitza Institute for Physical Problems Russian Academy of Science, Moscow
WORLD POPULATION FROM 2000 BC TO 3000 AD1 -- DATA OF BIRABEN, 2 -- BLOW-UP, 3 -- DEMOGRAPHIC TRANSITION, 4 -- STABILIZED POPULATION, 5 --ANCIENT WORLD, 6--MIDDLE AGES,7--MODERNITY, 8--RECENT HISTORY
PASSAGE THROUGH THE POPULATION TRANSITION 1– FRANCE, 2 – GERMANY, 3 – RUSSIA, 4 – USA, 5 – MAURITIUS, 6 – SRI LANKA, 7 – COSTA RICA, 8 – WORLD
WORLD DEMOGRAPHIC TRANSITION ANNUAL GROWTH AVERAGED OVER A DECADE1 – DEVELOPED AND 2 – DEVELOPING COUNTRIES
GLOBAL POPULATION IS A DYNAMIC SYSTEM MANKIND IS A SINGLE SPECIES Homo sapiens SYSTEM IS COUPLED BY INTERACTIONS GROWTH IS STATISTICALLY DETERMINED AND DYNAMICALY SELF-SIMILAR, HENCE IT SCALES LIMITS OF SCALING ARE SET BY LIFE SPAN GROWTH IS PROPORTIONAL TO SQUARE OF GLOBAL POPULATION AND IS NON-LINEAR MAIN ASSUMPTIONS MADE IN MODELING
MAIN RESULTS OF MODELLING GLOBAL POPULATION GROWTH BLOW-UP OF POPULATION GROWTH: GROWTH RATE: GROWTH BEFORE AND AFTER: CONSTANTS: POPULATION LIMIT: BEGINNING: PEOPLE WHO EVER LIVED: INSTANTANEUS EXPONENTIAL GROWTH:
GROWTH AND DEVELOPMENT DESCRIBED THROUGHOUT ALL OF HUMAN EXISTENCE GROWTH IS CULMINATED BY DEMOGRAPHIC TRANSITION — A REVOLUTIONARY CHANGE GLOBAL POPULATION LIMIT AT 10 –12 BILLION PEOPLE, WHO LIVED ON EARTH 100 BILLION PERIODS OF PAST HISTORY AND PREHISTORY SEEN ON A CONTRACTING TIME SCALE INTERNAL FACTORS DETERMINE TRANSITION, AND NOT BY ENVIRONMENT OR RESOURCES PRINCIPAL RESULTS OF THEORY
POPULATION OF THE WORLD1750–2200 1 –PROJECTIONS BY IIASA AND UN, 2 – MODEL, o – 1995 3 – BLOW-UP, 4 – DIFFERENCE OF MODEL AND PROJECTIONSx5 times
POPULATION OF MANKIND FROM ORIGINS AND INTO THE FORESEEABLE FUTURE
AGE DISTRIBUTIONS IN THE DEVELPED AND DEVELOPING WORLD IN 1975 AND 2000
CHANGE IN AGE DISTRIBUTION FOR GLOBALPOPULATION1 – AGE GROUP YONGER THAN 14 YEARS, 2 – OLDER THAN 65 YEARS 3 – OLDER THAN 80, A – DEVELOPING, B – DEVELOPEDCOUNTRIES
Zero growth rate Stabilized population New age structure New time structure Ethnic changes Massive migrations ? Changes in mobility ? Predominance of old generations setting challenges for health and social security Further globalization Alternative of stagnation or new development ? Deindustrialization Transition to an information society Expansion of services: health,education,science Emergence of new priorities and values in consumption,environmnt CONSEQUENCES OF GLOBAL DEMOGRAPHIC REVOLUTION DEMOGRAPHIC ECONOMIC
RIGHT FROM THE BEGINNING, GROWTH OF MANKIND WAS DETERMINED BY GENERALIZED INFORMATIONAL FACTORS THAT MODERATED SOCIAL EVOLUTION AND DEVELOPNENT THE GLOBAL DEMOGRAPHIC TRANSITION TO A STABILIZED POPULATION IS DETERMINED BY THE LIMITS OF THE INFORMATION SOCIETY THE FUTURE WILL BE DETERMINED BY THE «SOFTWARE» — CULTURE OF AN INFORMATION DOMINATED WORLD, RATHER THAN THE «HARDWARE» OF INDUSTRY, AS IN THE PAST PRINCIPLES OF META-ECONOMICS
WHAT DRIVESDEVELOPMENT? ‘THE FAILURE TO UNDERSTAND THAT THE ROOTS OF ECONOMIC BEHAVIOUR LIE IN THE REALM OF CONSCIOUSNESS AND CULTURE LEADS TO THE COMMON MISTAKE OF ATTRIBUTING MATERIAL CAUSES TO PHENOMENA THAT ARE ESSENTIALLY IDEAL IN NATURE.’ FRANCIS FUCUYAMA
IS THE DOMINANCE OF THE MARKET, WITH ITS SHORT RANGE TIME SCALE A REACTION TO D.T. CAN THE DILEMMA OF SELF-ORGANIZATION v.s. ORGANIZATION FIND ITS RESOLUTION CAN A DECREASE IN MILITANCE BE EXPECTED IN A WORLD WITH A STABILIZED POPULATION ? CAN IN THIS WORLD LONG RANGE SOCIAL ISSUES BE FACED BY GLOBAL GOVERNANCE, NOW CONSPICIOUSLY ABSENT ? WILL GLOBAL PROBLEMS HAVE A BETTER CHANCE IN AN EMERGENT NEW WORLD ? ISSUES IN THE POST — TRANSITION WORLD
