Redefining Prosperity The Economics of Sustainability Heather Reynolds Department of Biology T-200 Living a Sustainable Life
Agenda I.Conventional economics & prosperity as growth II.Abundance or limits? III.Ecological economics & redefining prosperity
I. Conventional economics & prosperity as growth
(from Daly 1996) HouseholdsBusinesses $ $ Goods and services Factors of production (labor) Conventional Economics Economic development Economic growthGNP, GDP, total & per capita
Weaknesses? leaves out the equitability of income distribution leaves out foreign debts ignores non-monetary aspects of quality of life e.g. volunteerism, growing own food, homemaking, bartering, etc. counts any $$ transaction as good even $$ spent on crime, sickness, natural disasters, pollution, etc. doesn’t consider environmental depletion & degradation external costs, generally not factored into market prices assumes more consumer goods increases our well-being
II. Abundance or limits?
“If we are going to carry on growing, and we will, because no country is going to forfeit its right to economic growth, we have to find a way of doing it sustainably.” -Tony Blair Real GDP per working-age person in the United States, HouseholdsBusinesses $ $ Goods and services Factors of production
“The idea that the natural world is inevitably destroyed by human industry, or than excessive demand for resources causes environmental ills, is a simplification….Design based on nature’s effectiveness…can solve rather than alleviate the problems industry creates, allowing both business and nature to be fecund and productive.” -William McDonnough & Michael Braungart

We the undersigned, senior members of the world's scientific community, hereby warn all humanity of what lies ahead. A great change in our stewardship of the earth and the life on it is required, if vast human misery is to be avoided and our global home on this planet is not to be irretrievably mutilated. World Scientists’ Warning to Humanity November, 1992
Millennium Ecosystem Assessment Overview of Findings Over the past 50 years, humans have changed ecosystems more rapidly and extensively than in any comparable period of time in human history, largely to meet rapidly growing demands for food, fresh water, timber, fiber and fuel The changes that have been made to ecosystems have contributed to substantial net gains in human well-being and economic development, but these gains have been achieved at growing costs in the form of the degradation of many ecosystem services, increased risks of nonlinear changes, and the exacerbation of poverty for some groups of people The degradation of ecosystem services could grow significantly worse during the first half of this century and is a barrier to achieving the Millennium Development Goals The challenge of reversing the degradation of ecosystems while meeting increasing demands for their services can be partially met under some scenarios that the MA has considered but these involve significant changes in policies, institutions and practices, that are not currently under way MEA Full slideshow of findings.
Degradation and unsustainable use of ecosystem services Approximately 60% (15 out of 24) of the ecosystem services evaluated in this assessment are being degraded or used unsustainably The degradation of ecosystem services often causes significant harm to human well-being and represents a loss of a natural asset or wealth of a country Millennium Ecosystem Assessment MEA Full slideshow of findings.
1.0 Earths used by humanity Earths available ‘61‘81 ‘99 Year # Earths Overshoot Analysis based on six human activities assuming current levels of technology: agriculture (cropland), raising animals (pastureland), harvesting timber (timberland), fishing (fishing grounds), construction of gray infrastructure (consumed land), burning fossil fuels (energy land).

Millennium Ecosystem Assessment Ecosystem Services and Their Links to Human Well-being MEA Ecosystems and human well-being: A framework for assessment. Random House Dictionary definition: a successful, flourishing, thriving condition, esp. in financial respects; good fortune.
Redefining Prosperity Growth vs. Development
GrowthDevelopment vs. New roadsPublic & alternative transportation (trains, buses, bikes, pedestrian trails) Clearing forests for agricultureUrban agriculture (rooftops, yards, vacant lots) More coal plantsEnergy efficiency & renewables More housing divisionsInfill & redevelopment More private shopping, entertainment and recreation districts More public spaces for art & theatre more greenspaces
Redefining Prosperity Quality of Life Indicators
Costanza et al Ecological Economics 61:
Achieving Prosperous, Sustainable Economies Relocalization sustainable scale; fit to local ecosystems diversified; local production, local markets alternative transportation compact, mixed-use design energy-efficient homes emphasis on self-sufficiency local food, organic practices (food security) Stabilized population and consumption Fair distribution of wealth
