Lifeboats: Civilization Triage

In this scenario, supplies of high quality fossil fuels decline rapidly, the economy fails and human contributions to global warming collapse but lag effects and positive feedbacks in the climate system continue to drive an acceleration of global warming.

As of 2007, an increasing number of scientists believe it may already be too late to avoid catastrophic climate change.50See a review of the latest evidence of acceleration in climate change well beyond any previously credited predictions see The Big Melt:Lessons from the Arctic Summer of 2007 In the Lifeboat scenario the adverse symptoms of the Brown Tech and Earth Steward scenarios combine to force a progressive collapse in most forms of economy and social organisation. Local wars, including use of nuclear weapons accelerate collapse in some areas but the failure of national systems of power prevent global warfare. Successive waves of famine and disease breakdown social and economic capacity on a larger scale than the Black Death in medieval Europe leading to a halving of global population in a few decades.

Low tech methods such as snaring and trapping are widespread but the efficiency of firearms and their additional value as the symbol of security gives status and importance to the skilled hunter and gunsmith in a world of want and fear. Powder and other components for amunition become strategic materials.

New forms of oasis agriculture that are low input versions of the Brown Tech intensive systems evolve that stabilise food production as chaotic seasons make traditional field agriculture and horticulture almost impossible. Forest and rangeland hunting and harvesting become the predominant use of resources over large regions supporting nomadic bands. Warrior and gang cults provides meaning in a world of grief and violence, leading to the development of new religions and even languages that attempt to make sense of people’s lives.

Derelict factories Philidelphia USA 2005 In the Lifeboat scenario derelict urban buildings provide salvaged material traded under difficult conditions (lack of security) to peri urban and rural economies in exchange for food and other basic needs.

Urban areas are largely abandoned and dangerous but remain valuable as quarries for salvaging materials especially metals. Suburban landscapes become ruralised into defensive hamlets making use of salvaged materials, urban storm water and surplus building space for mixed household economies.

The impacts are very patchy with worse effects in high density previously affluent and urbanised countries. In the most remote regions remnants of hunter-gatherer and pioneer farmer cultures are better able to weather the changes. The relative abundance and ongoing availability of high quality metals and other materials make a critical technological distinction from that of ancient traditional hunter gatherer cultures.

In the Lifeboat scenario, existing intentional communities in rural areas with shared facilities and economy may be best placed to maintain collective decision making as well as information retention and skills training in low tech methods of construction, food production, health maintenance.

Mountain regions, especially with surviving glacier fed rivers allow hydroelectric systems to be maintained and rebuilt on a smaller scale. Nutrient rich glacier fed rivers also sustain intensive irrigated agriculture. In some localities, especially in favourable regions with accessible energy and agricultural resources, communities analogous to the monasteries of the early medieval period provide basic knowledge and skills to their surrounding communities and are thus protected by the locals from the ravages of local warlords and pirates. These communities, mostly in rural and suburban areas, and based on pre-collapse efforts of intentional communities or rich benefactors, pursue the task of saving and condensing knowledge and cultural values for the long dark ages ahead.

“Civilisation triage”51Triage is a process for managing the medical care of the injured during war or natural disasters where not all victims can be saved with the available resources. Those that have a chance of survival are the focus of most attention while the others are given palliative care to ease their pain. refers to the processes by which remaining social capacity (beyond meeting immediate basic needs) are focused on conserving technology and culture that could be useful to a future society, once energy descent is stabilised after a precipitous but limited collapse process. This is not the dominant process of the scenario but the most significant in terms of future cultural capacity. The Christian monasteries that saved many of the elements of Greco-Roman culture and later provided the foundations for the Renaissance of Western civilisation is one historical example that could serve as a model for understanding how this process might work.

At its extreme, this scenario describes many of the elements of the Collapse Long Term future in which there is a complete breakdown in the lineage of industrial civilisation such that future simple societies retain nothing from what we created through industrial civilisation. Drawing a distinction between this scenario and total collapse may seem pedantic but the reasons are important. In the Collapse Long Term scenario, any future civilisation that could emerge only learns from the lessons of ours via archeology and perhaps long attenuated mythic stories. In the Lifeboat scenario the retention of cultural knowledge of the past combined with a moderately habitable environment allow new civilisations to emerge that build on at least some of the knowledge and lessons from ours.

Three factors may prevent the continuous free fall to a very low global population of hunter gatherers

Three factors may prevent the continuous free fall to a very low global population of hunter gatherers surviving on the fringes of the Arctic of a hotter planet.

  • The first is the wild card created by the mixing of the world’s biota, most notable the large numbers of tree and other species that exhibit what foresters call “exotic vigour”.52Plants that grow better in foreign environments than in their original environment. Usually called invasive species by conservationists. See “Weeds or Wild Nature ” at Holmgren Design Services website This allows new recombinant ecosystems to stabilize many environments that climate scientists are now saying will become uninhabitable in extreme climate change. The release of critical minerals, most notably phosphorus over the last 200 years into the biosphere may allow these new ecosystems to ultimately achieve biological productivity exceeding that possible from pre-existing systems.
  • Secondly the flooding of large areas of coastal lowlands complete with complex reef structures from flooded cities and infrastructure may also create the conditions for highly productive shallow waters and estuaries. These types of ecosystem are some of the most biologically productive ecosystems on the planet.53In the 1960’s a massive earthquake around Valdivia in southern Chile created huge new wetlands following subsidence of the land. These wetlands had very high biological productivity based on an exotic aquatic plant that supported huge new populations of swans. The wetlands were recognised as being of global conservation significance under the RAMSAR convention. More recently pollution from a local cellulose plant has lead to a collapse in the population of swans.
  • Thirdly, the precipitous drop in human numbers and their initial tendency to remain relatively aggregated to make use of the huge resources from industrial salvage materials (and for security) should see very large regions able to recover without harvesting and other impacts from people.

If the knowledge of ecological processes and their creative manipulation using minimal resources are retained and developed in the Lifeboat communities, then survival and resurgence of a more than minimalist culture may allow global human population to be sustained at perhaps half, rather than one tenth, of current levels. More importantly it may be possible to embed the wisdom of the lessons learnt so that unconstrained human growth does not repeat such an intense cycle. Clearly these last thoughts are highly speculative but build from the same linage of permaculture thinking developed over the last thirty years that informs the rest of the scenarios.
