  • By investigating the human-nature dynamics of these past cases of collapse, the project identifies the most salient interrelated factors which explain civilisational 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."
  • The study challenges those who argue that technology will resolve these challenges by increasing efficiency: "Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource extraction, so that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use."

  • the scientists point out that the worst-case scenarios are by no means inevitable, and suggest that appropriate policy and structural changes could avoid collapse, if not pave the way toward a more stable civilisation.

  • “If I was Japan’s worst enemy trying to figure out a strategy to drive it into a crisis in 10 years’ time, my strategy would be to get the Japanese to do exactly what they are doing, which is to over-harvest their main source of protein.”
  • “There is a parallel based on the same fundamental mechanisms of the economic collapse that we’re seeing now and the collapse of past civilisations such as the Maya,”

  • “When people talk about the greater efficiency of dictatorships, they are forgetting that a dictatorship is no more likely than a democracy to make a wise decision,”
  • “If we continue to operate non-sustainably, then in 50 or 60 years, the US and Japan and Europe will be in bad shape. But my friends in the highlands of New Guinea will be fine. Some of my friends made stone tools when they were children and they could just go back to what their ancestors were doing for 46,000 years. New Guinea highlanders are not doomed,”
  • “The first world lifestyle will be doomed if we don’t learn to operate sustainably.”

    What does the future hold for the world's largest renewable energy source, hydropower? Hydropower is an incredibly old source of energy, tracing its usage back to the watermills that have been a staple of civilisations since ancient times. Today, it is the largest source of renewable energy in the world, with an installed capacity of over 1126GW in 2018. Hydropower is particularly prominent in China, where the world's largest power station Three Gorges power plant in Hubei province produces 22.5GW. Other massive projects also dot the country, including the Xilodu (12.3GW) and Longtan (6.3GW) dams.
