Principles for the Pulse that is Peak Oil « integral permaculture

From David M. at Integral Permaculture; “Howard Odum was of the opinion that all systems on all scales pulse.  Storages gradually accumulate, consumers consume and develop, and eventually decline, and then dispersing materials that will be used in the next pulse.” And if “energy flows, storages, transformations, feedbacks, and sinks” are central to any system, man-made or otherwise, we can see that the peaking of world oil production is going to have a huge effect.”

Also from David’s post, a quote from Holmgren; “…If there is a single most important insight for permaculture from Odum’s work it is that solar energy and its derivatives are our only sustainable source of life. Forestry and agriculture are the primary (and potentially self-supporting) systems of solar energy harvesting available. Technological development will not change this basic fact. It should be possible to design land use systems which approach the solar energy harvesting capacities of natural systems while providing humanity with its needs. This was the original premise of the permaculture concept. While available solar energy may represent some sort of ultimate limit to productivity it is other factors which primarily limit it.”

Pulsing (Odum, 2007, p. 56) 

“A century of studies in ecology, and in many other fields from molecules to stars, shows that systems don’t level off for long. They pulse. Apparently the pattern that maximizes power on each scale in the long run is a pulsed consumption of mature structures that resets succession to repeat again. There are many mechanisms, such as epidemic insects eating a forest, regular fires in grasslands, locusts in the desert, volcanic eruptions in geologic succession, oscillating chemical reactions, and exploding stars in the cosmos. Systems that develop pulsing mechanisms prevail. The figure above includes the downturn for reset that follows ecological climax. In the long run there is no steady state” (Odum, 2007, p. 54).     Holling, Gunderson, & Ludwig, Panarchy and Resilience

“The aspect of resilience and panarchy that is most novel and significant concerns the “back-loop” phase when resisting structures and institutions start to break down or transform, releasing the chance for a renewed system to emerge. The many ecosystem examples are matched by many business examples where technology shapes products from sneakers, to automobiles, to electrical appliances. At that moment, novelty that had been simmering in the background can emerge and be stimulated. And new associations begin to develop among previously separate innovations. The big influence comes from discoveries that, at that time, emerge from people’s local experiments at small scales, discoveries that can emerge at times of big change, to trigger bigger changes at large scales. That process highlights the keys for the future” (Holling, 2009).

As a follow up to Dave Tilley’s article on renewable rhythms, and in celebration of summer solstice, I would like to discuss the idea that fossil fuels have allowed us to suppress or even ignore pulses of Nature and our own biorhythms. We have adopted artificial pulses of industrial production and consumption with attempts to create continuous growth. Fossil fuels allow us to create a seamlessly, climate-controlled, homogenous monoculture that blurs night into day, and summer into winter. It even homogenizes trends, with everything always improving and going up without a break in the action. This separates us from Nature and creates the impression of invincibility. How does this invincibility present in our dominant culture, and what does it mean as our culture transitions into descent? Continue reading Time and tides wait for no man

Renewable Power Rhythm

The Rhythm of Power Availability in the Post-Prosperous Way Down World

by David Tilley, University of Maryland

Dr. H.T. Odum and his wife Betty spent much of their careers developing thoughts on what became the book, A Prosperous Way Down (PWD). Others, like Richard Heinberg, have been successful at bringing the seriousness and reality of a PWD to a larger audience. There is a small and growing amount of thinking and talking about doomsday or armageddon scenarios that many think will prevail as fossil fuels become scarce.

Hunger Games Capitol City (Collins, Ross, Lionsgate)

National Geographic has given us the TV reality program Doomsday Preppers. Its presence and popularity reflects the public’s perception that change is on its way. I think the success and impetus for Suzanne Collins’ Hunger Games is a response to the reality of a PWD. Rather than cover what the way down will be like in this post, I wanted to share my thoughts on what one important aspect of life might be like once we reach “down”. That is, the time after decline is finished, when the fossil fuels are gone and society is running almost completely on renewably sourced energies. I explore how peoples’ behaviors may change once they are driven by flow-limited energy sources rather than storage-driven sources in the post carbon world? Flow-limited sources cannot be controlled and stored easily so society will be more effective if it adapts to the rhythm and availability of energy. Continue reading Renewable Power Rhythm
