NASA-funded study finds: Our civilization faces similar threats of collapse as the Mayans experienced

NASA-funded study finds: Our civilization faces similar threats of collapse as the Mayans experienced | Amazing Science | Scoop.it

Natural and social scientists develop new model of how 'perfect storm' of crises could unravel global system.


A new study sponsored by Nasa's Goddard Space Flight Center has highlighted the prospect that global industrial civilization could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution.


Noting that warnings of 'collapse' are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that "the process of rise-and-collapse is actually a recurrent cycle found throughout history." Cases of severe civilizational disruption due to "precipitous collapse - often lasting centuries - have been quite common."


The research project is based on a new cross-disciplinary 'Human And Nature DYnamical' (HANDY) model, led by applied mathematician Safa Motesharrei of the US National Science Foundation-supported National Socio-Environmental Synthesis Center, in association with a team of natural and social scientists. The study based on the HANDY model has been accepted for publication in the peer-reviewed Elsevier journal, Ecological Economics.


It finds that according to the historical record even advanced, complex civilizations are susceptible to collapse, raising questions about the sustainability of modern civilization: "The fall of the Roman Empire, and the equally (if not more) advanced Han, Mauryan, and Gupta Empires, as well as so many advanced Mesopotamian Empires, are all testimony to the fact that advanced, sophisticated, complex, and creative civilizations can be both fragile and impermanent."


By investigating the human-nature dynamics of these past cases of collapse, the project identifies the most salient interrelated factors which explain civilizational decline, and which may help determine the risk of collapse today: namely, Population, Climate, Water, Agriculture, and Energy.


These factors can lead to collapse when they converge to generate two crucial social features: "the stretching of resources due to the strain placed on the ecological carrying capacity"; and "the economic stratification of society into Elites [rich] and Masses (or "Commoners") [poor]" These social phenomena have played "a central role in the character or in the process of the collapse," in all such cases over "the last five thousand years."

Population clock shows Japanese face extinction in 1,000 years

Population clock shows Japanese face extinction in 1,000 years | Amazing Science | Scoop.it

Japanese could become extinct in 1,000 years if current population trends continue, according to researchers. Researchers at Tohoku University Graduate School of Economics in Sendai unveiled a population clock — available on the university's website — that showed the nation ending up with no children aged under 15 by May 18, 3011.

 

The calculation is based on the fact that the current population of children aged up to 14 — 16.6 million — is shrinking at the rate of one every 100 seconds, Agence France-Presse reported. The researchers reportedly did not take into account potential disasters, wars, or other global changes. "If the rate of decline continues, we will be able to celebrate the Children's Day public holiday on May 5, 3011 as there will be one child," AFP cited Hiroshi Yoshida, an economics professor at Tohoku University, as saying. "But 100 seconds later there will be no children left. The overall trend is towards extinction, which started in 1975 when Japan's fertility rate fell below two."
