Peak Oil: It happened, as predicted in the US King Hubbert
Global (Campbell, 2009)
Three convincing points: Importance of “Peak Oil” Decreasing oil production and increasing demand. Declining Energy Return on Investment (EROI) Low EROI of alternatives
DEFINITION of EROI Energy return on investment for an activity: Energy delivered to society EROI = __________________________ Energy put into that activity
Global Energy Trouble Lower Energy Future Oil and NG = >55% Energy Supporting Society
Solutions to environmental problems would be grounded in the technology from natural systems so that the human engineering required would be supplementary rather than primary (Odum 1963) The design of ecosystems for the mutual benefit of humans and nature. (Mitsch and Jogensen 1989)

Ecological Engineering &Traditional Ecological Knowledge (TEK) Ecological Engineering 45 (2012) 30-44 Ecological Engineering 36 (2010) 839-849 NSF grant Stewart Diemont et al. 2012
TEK: Philosophy • Ecosystem & connections: “No such thing as nature that exists independent of humans and their activities” (Pierotti and Wildcat 2000) • “Conservation through use” • Uncertainty and unpredictability are intrinsic to all ecosystems. “Control” is impossible. TEK adaptive over time. • Long-term vision • A failure of current resource managment is a lack of attention to long-term implications. • Iroquios- seventh generation • Similarities with Ecological Engineering & Systems Ecology

“Some older ways, persisting in cultural memory, may be needed again when times of lower energy return” (Odum 2007)
Conclusions • Peak Oil will result in a lower energy future. • Ecological Engineering can help with designs based on ecosystem processes and renewable energy. • Traditional Ecological Knowledge can inspire designs for future. • Come to AEES 2013 at Michigan State (June 9-12)
Ecological Engineering Can Help (Odum, 1996)
How Can TEK Help?Example: Water Management • Problems: Water scarcity and Stormwater runoff • Design urban areas to capture and reuse stormwater • Past cultures adapted to climate change with water catchment and this is advocated for our future (Pandey et al. 2003)

Why helpful for Ecological Engineering? design ecosystems for the mutual benefit of humans and nature.
Why helpful for Ecological Engineering? Indigenous cultures relied on renewable energies to design ecosystems for the mutual benefit of humans and nature.

Petroleum production in Norway in 1970 – 2008 EROI Example:
Energetic cost of petroleum production in Norway in 1991 – 2008 Grandell, 2011
EROI of Norwegian petroleum production in 1991 – 2008 EROI for Norwegian oil has declined by half in 11 years

Change of Direction in Information Flow “People from an industrial-agricultural region who go to a low energy country to advise on improving agriculture can help only if there is a cheap fuel supply for another zone of fossil fuel agriculture. As fuel prices rise and fuel use decreases, the advice will come in the opposite direction.” TEK “can speed … emergence of agroecological principles, … and biodiversity conservation … in industrial and developing countries”–Miguel Altieri Odum 2007 2010… Green Revolution
