Cognitive and behavioral paradigm shifts would offer ‘guarded’ optimism for the future. A preview of this afternoon’s discussion:
1. Realistic meta-level picture of humanity’s relationship with the planet
2. Talk about that relationship and the conceptual meaning of sustainability
3. Discuss the need for ‘transformative’ change and one approach to achieving future sustainability
The Problem Climate change is not the problem. Water shortages, overgrazing, erosion, desertification and the rapid extinction of species are not the problem. Deforestation, Deforestation, reduced cropland productivity, Deforestation, reduced cropland productivity, and the collapse of fisheries are not the problem. Each of these crises, though alarming, is a symptom of a single, over-riding issue. Humanity is simply demanding more than the earth can provide. Climate change Witnessing dysfunctional human behavior
Deforestation Desertification Collapse of fisheries Rapid extinction of species Supply = 1 Earth
Today’s reality: Global Resource Overshoot How do we know we are
- living beyond our resource means? - exceeding global capacity? - experiencing resource overshoot?
• Millennium Ecosystem Assessment Released in 2005, the Millennium Ecosystem Assessment was a four-year global effort involving more than 1,300 experts that assessed the condition of and trends in the world’s ecosystems. The Assessment found that in the last half of the 20th century, humans changed ecosystems more rapidly and extensively than in any comparable period of history, primarily to meet growing needs for food, freshwater, timber, fiber, and fuel.

A population’s eco-footprint (demand) is the area of land and water ecosystems (bio-capacity) required to produce the resources that the population consumes, and to assimilate the wastes that the population produces, wherever on Earth the relevant land/water may be located.
Human Demand: Our Global ecological Footprint

Missing: Four Phantom Planets
If everyone on Earth lived the consumer lifestyles of North Americans, we’d need three or four additional Earth-like planets.
Problem: “Good planets are hard to find.” • Humanity is already consuming resources at an unsustainable rate.
• We are already exceeding planetary boundaries.
• We are putting earth systems and human civilization at risk. “…the continued functioning of the Earth system as it has supported the well-being of human civilization in recent centuries is at risk. Without urgent action, we could face threats to water, food, biodiversity, and other critical resources: these threats risk intensifying economic, ecological, and social crisis, creating the potential for a humanitarian emergency on a global scale.” “[We are] burning through [global] resources in the name of prosperity, as if there is no tomorrow”
Ban Ki-Moon (4/20/12) What is sustainability? Sustainability conceptually describes an economy and full set of societal endeavors, the demands of which are in equilibrium with basic ecological and resource support systems Resource Sufficiency Evaluation (RSE)
What is sustainability?
Despite the confusion, ‘sustainability’ is not a difficult concept Sustainability simply means that the human family must live more equitably within the productive means of nature. Humans cannot consume essential renewable resources faster than Nature replenishes them nor generate material wastes faster than nature can assimilate and recycle them. No society is sustainable if it maintains itself or grows by depleting its income-producing wealth or ‘capital’.
It follows that: The world community must learn to live on the annual income generated by both its manufactured capital and natural capital. Economic Implications
A sustainable economy thrives on the annual income of its capital assets: finance capital, manufactured capital natural capital. At ‘carrying capacity’ a sustainable economy is a non- growing or steady-state economy. A steady-state economy is characterized by a constant or modestly fluctuating through-put of energy and material resources (‘natural income’) that leaves its capital intact. A steady-state economy is not a stagnant economy. It does not grow but can develop dynamically. Society steadily improves as technologies evolve, new industries replace old, and human well-being increases. What’s to fear? What’s not to like?? Resource overshoot
Possible Solutions
“Our collective challenge: Scaling down the human endeavor”
e = < e RI D P AC T = R Cap
Resource demands must be less than or equal to capacity
Possible Solutions

In fact the world is going in the other direction (e.g. cars in China)!
Possible Solutions

Can we ‘decouple’ our economy from the demands
we place on natural capital?
Will ‘greening’ our global economy lead to a sustainable world? Technology
Mr. T Technology advancement is not the answer to the sustainability challenge.
It is necessary, but not sufficient! Greening the economy is not the answer to the sustainability challenge.
It is necessary, but not sufficient! Resource efficiency improvement is not the answer to the sustainability challenge.
It is necessary, but not sufficient! Resource Sufficiency Evaluation (RSE) Greening the economy is necessary, but not sufficient.
In economics the Jevons paradox is the proposition that technological progress that increases the efficiency with which a resource is used tends to increase (rather than decrease) the rate of consumption of that resource. Jevons observed that technological improvements that increased the efficiency of coal use led to increased consumption of coal in a wide range of industries. He argued that, contrary to intuition, technological William Stanley Jevons improvements could not be relied upon to 1865 – English Economist reduce fuel consumption.
Resource Sufficiency Evaluation (RSE)
Greening the economy is necessary, but not sufficient.
While green technologies may help to de-link resource extraction from economic growth, they will not ensure progress towards sustainability. Complete mitigation of the global warming and climate disruption crisis
Sustainability Achieving food security
Sustainability Solutions 1. Change the political mandate from economic growth to shared economic development within planetary limits. Our challenge, should we choose to accept it: Write a new, more adaptive cultural narrative
Sustainable material growth is an oxymoron.
The economic policy emphasis must shift from efficiency and growth (merely getting bigger) toward sufficiency, equity and development (qualitative improvement, getting better).
The underpinning values of society must shift from competitive individualism, greed, and short- term self-interest, toward cooperative mutualism, community, and humanity’s long-term collective interest in survival. Motivation and Rationale? It’s in everyone’s long-term best interest
Individual and national interests have converged with humanity’s common interests. That is; Sustainability is a collective problem that demands collective solutions (no country can become sustainable on its own); Failure to act for the common good will ultimately lead to civil insurrection, geopolitical chaos, resource wars and ecological destruction. Cognitive Steps Forward
Recognize that on a biophysically-constrained planet, everything is connected to everything else: economic policy is ecological policy is social policy. Re-legitimize public planning at all levels of governance. We need comprehensive mitigation and adaptation strategies for global change (markets alone can’t achieve sustainability). Abandon the cult of consumerism. The material ethic is spiritually empty and ecologically disastrous. Cultivate saving and conserver values over shopping and consumer values.
Solutions 1. Change the political mandate from economic growth to shared economic development within planetary limits.
2. Increase media attention to population and sustainability issues. Solutions 1. Change the political mandate from economic growth to shared economic development within planetary limits.
2. Increase media attention to population and sustainability issues and serial dramas for behavioral change.
3. Incorporate resource sufficiency evaluation (RSE) and reporting into national and global governance. The Global Challenge
