The Mystery of Sum up Easter Island

Indicators Definitions, jargon & calculations & Concepts

Branches: Food system Economy Industry Easter Island • Brundtland commission (UNED, 1983): [… as meeting] “the needs of the present without compromising the ability of future generations to meet their own needs.“

• Officially introduced as a new science at the World Congress "Challenges of a Changing Earth 2001" in Amsterdam by the International Council for Science.

• Its an interdisciplinary science of natural sciences, economy, engineering, humanities, ethics and more.

• It aims at providing ways to reduce human impact and align it with the Earth’s .

definition

“Sustainability is the capacity of any system or process to maintain itself indefinitely. Sustainable development thus is the development of a human, social and economic system able to maintain itself indefinitely in harmony with the biophysical systems of the planet.….its core objective…..to provide to everybody everywhere and at any time the opportunity to lead a dignified life in his or her respective society….This demand for a high quality of life…include[s] a descend standard of living, social cohesion, full participation, and a healthy environment. “

Institutional Sustainability Cultural Sustainability

So why do we need to think about sustainability at all?

 a detectable effect on ecological systems on a global scale (e.g. climate change, biodiversity)  growth  Energy Consumption (peak oil)  Poverty, hunger and malnutrition

Above all, these problems are inter related and require a new holistic approach beyond conventional disciplines

Sustainable jargon

• Non fiscal capital, services, ecosystem valuation, externalities, (biocapacity), , weak and hard sustainability

History of concerns

 Malthus (1798) "The power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio...“ ,Malthus T.R. 1798. An essay on the principle of population.  Tragedy of the Commons – Hardin (1962)  Limits to Growth (1972) – World3 dynamic system model  Vitousek et al. (1986) humanity’s appropriation of the biosphere  Rees and Wackernagel (1994)  Ecosystem Millennium report (2005)  International Assessment of Agricultural Knowledge, Science and Technology for Development (2008)  Planetary boundaries (2009) Ecological Economics

• Dynamics and co-evolution between the human economy and natural systems. • Develop sustainable economic systems • Open vs. Closed systems, subsets and wholes. Learning from natural .

• substitutability • Well-being and growth. • dematerialization, degrowth

Industry and design

 Industrial ecology – designing sustainable industrial systems  Life Cycle Analysis, Material flow Analysis and Net Energy Analysis

• Linear design and thought – cradle to grave vs. c2c

 Population has doubled in the last 50 years. ~ 9 billion by 2050.  Increase in population and food consumption per capita  doubling (or even tripling) of food demand by 2050.  ~1 billion people are hungry, >1 billion over fed, overweight.  Arable land increase 1.2->1.5 billion ha from 1950-1999; Grain production has doubled.  Doubling of food production either doubling of land or double in yield  ~1/3 of the world's cropland abandoned during the past 40 years due to erosion. More lost to , , and salinization; irrigation doubled; global fertilization increased by 500%  USA food system [global]: 50% of total land [40%], 80% of fresh water [70%], and 17% of fossil fuel [30%].  Global food allocation: 62% food, 35% animal feed,3% bioenergy seed and other industrial products.

 Can humanity achieve sustainable food production systems at the beginning of the 21st century?  Considering the environmental, social and economical implications how do biofuels score? And how can we measure such a score? Sustainability indicators

 Qualitative tools to assess sustainability  There exist many indicators, ecological, economical, social or a combination of them.  For example: the ecological footprint - It transforms human impact into 5 land types - aggregates it into global hectares.

 The Gross national happiness (GNH)  going beyond GDP - conceptualized by the king of Bhutan - quality of life and social progress

Sum up

 A biomimcry concept (A cycle, cyclic, stable over time)  implement in human systems  Contains dimensions of environment, economy, and social aspects with an ethical component.  Holistic - transects all human disciplines  Aligning human impact with Earth’s carrying capacity while providing a descend well being to everyone.
