  3. 3. Ecological Footprint The amount of productive land and water a given population requires to produce all the resources they consume and take in all the waste they make using prevailing technology* - Onisto, et al 1998 From a school perspective, Ecological Footprint = The space required to support all the inputs and outputs of the school body.* Based on the premise that we live in a finite world. The earth has limited resourcesand limited waste assimilation capacity.
  4. 4. Are We Getting Too Big For Our House? House
  5. 5. Who Is Getting What? Eco-footprint helps us understand that a small proportion of the population is consuming a large amount of the resources Approx 20% of the global population consumes 80% of resources. Canada fits into the high- consuming category. Can you identify 5 countries on a world map that each picture is referring to? Top picture: USA, Canada, Australia, New Zealand, United Kingdom Bottom Picture: Mozambique, India, Ethiopia, Vietnam, Uganda
  6. 6. Components of Ecological Footprint SIX HUMAN ACTIVITIES THAT REQUIRE SPACE1. Growing Crops2. Grazing Animals3. Harvesting Timber4. Catching Fish5. Accommodating Infrastructure (Housing, Transportation Systems, Industry, Built Up Land)6. Absorbing Carbon Dioxide Emissions (Burning Fossil Fuels)
  7. 7. A region’s (person,school) ecological footprintis the total area required toproduce the food andfibers that a regionconsumes, sustains itsenergy consumption, andgives space for itsinfrastructure. People consumeresources from all over theworld, so their footprintcan be thought of as thesum of these areas,wherever they are on theplanet.
  8. 8. If Everyone Lived Like Us We Would Need…… If everyone in the world lived the same way we do , we would need approx four planets to provide all the resources and manage all the waste of our population. How do we know this? The eco-footprint helps us to calculate the land required support our lifestyle and compares it to the capacity of the planet.

The height of each box is proportional to the regions average ecological footprint per person; and The width of the box is proportional to the population of the region. The OECD and non-OECD columns refer only to average ecological footprint per person.

  20. 20. What About Land For Other Species? People vs. nature Some people might remember that there are other species on the planet that also need land to survive. How much should we set aside for them? Questions for Students : What species are threatened due to reasons such as lack of habitat? What causes habitat destruction? Are there examples where we put some land aside for conservation purposes? How much land should we protect for other species? Why?

  22. 22. Sustainability Models
  23. 23. Sustainability Model vs. Ecological FootprintWe can calculate how much biological productive area we haveWe can calculate how much we are usingLiving sustainably means that we are not living beyond what isavailable
  24. 24. Measurements of Sustainable Development Generally look at the “supply side” of the equation. Such measurements put the whole onus for sustainable development on the producer. The “ecological footprint” looks at the “demand” side of the equation and places responsibility for sustainable development not only on the producer but on the consumer*.* As consumers we have a responsibility. Why are we throwing outso much food in the first place, are we making an effort to reduceour energy consumption, do we eat a diet suitable to our nutritionalneeds and level of activity. Our footprint directly relates to ourlifestyle and the choices that we make.

This is not actually the case. Italy is a good Due to the size of Australia and example here. It has an eco-footprint of 3.8their low population, they have a lot hectares – a lot closer to average available land ofmore land than what the population 1.9 hectares than Australia or America.uses. Italians have quite a high standard of living and Only developing countries like quality of life. So what does this tell us? That theyChina have a land use figure under live their lives quite differently, but notthe world average available land . necessarily more poorly.Due to China’s large population its For example, the design of Italian cities is veryown land available or biocapacity is compact, with a high reliance on public transport.1.1 per person, below its usage of So the eco-footprint can guide us on policies1.6. and strategies of how we can all live well, while recognising there is only one planet.
  27. 27. Message in a Nutshell Countries such as the United The richest fifth: States, Australia, Canada, Singapore, New Zealand, Hong Account for 86% of total private consumption Kong, and Sweden occupy expenditures, the poorest fifth 1.3%. footprints over 200% greater Consume 45% of all meat and fish, the than the 2.0 ha available per poorest fifth 5% global citizen. This is Consume 58% of total energy, the poorest dramatically contrasted to fifth less than 4% Bangladesh, Ethiopia, Pakistan, Consume 84% of all paper, the poorest fifth India, and Nigeria with 1.1% footprints of 1 ha or less per Own 87% of the world’s vehicle fleet, the capita. poorest fifth less than 1% (UNDP, 1998).In a world of limited resources and limited waste assimilation capacity, excessconsumption by the rich literally requires that others live in poverty if we are not toexceed the Earth’s physical carrying capacity.Ecological footprint analysis cuts through the illusion that we can improve the livingstandards of the poor without curbing the excess consumption of the rich.
