Different industrial sectors are matched up against resources they use in a matrix, so the economic intensity of each sector is converted into a resource intensity.
Imagine Japan, which is completely dependent upon imports of most raw industrial materials, and one can see how a footprint might mislead us into thinking Japan is totally unsustainable even if the trade relations with surrounding countries is in fact genuinely sustainable.
At each location a staff expert from the school answers student Ecological footprinting in an ib school. We can also get a crude understanding of the kinds of activities that have the greatest impact, such as food, transport or housing.
This latter factor represents the relative productivity of a particular type of land e. Your knowledge, professionalism, collaboration with staff, warmth, knowledge of students and instructional strategies - and much more - combined to make for a powerful experience. So one global hectare represents the average biocapacity of all hectares on earth.
Saying "I need 2. A further challenge is for an organisation to look at their influence, both on their own sector, their supply chain, and on the external infrastructure their business requires or leads to.
So you end up with an indication of the biocapacity that accounts for the area of land, the type of land, and the geographical location of the land.
The top-down method works very well for nations and geographical regions, and allows us to say that certain areas are generally consuming more or less than their fair share. This shows the relative productivity of a particular bit of land, so for example you can determine that cropland in the UK is x times as productive as cropland in Tibet.
You multiply the yield and equivalence factors by the ratio of tonnage to yield for each type of land being used. Biocapacity and ecological footprints are calculated as follows: Multiply the area in hectares by the yield factor, and by the equivalence factor.
New vocabulary An Understanding of how their actions affect the world around them Tools to address short and long-term local and global concerns Appreciation of the importance of making good choices when it comes to environmental consequences.
Biocapacity is divided into six main land types: We introduce the footprint concept as students discuss their own individual activities and impacts.
This all cancels out into a figure in global hectares. Limitations of eco-footprinting The ecological footprint is one indication of unsustainability. The more complex approach, input-output, takes economic data as a proxy for consumption levels.
In contrast, the bottom-up approach has a very fine granularity, since you have calculated the footprint for every product used, but you are likely to have an incomplete picture due to the difficult of LCAs and accounting for every resource used. For example, there is data for a variety of different kinds of cropland in the UK, but this still misses regional variations, the crops we might need to fulfil dietary requirements, and the crops we need to meet a reasonable demand profile for a wider area including exports to the continent.
Next, you need to calculate the biocapacity of that bit of land. How Green is Our School? But it would be misleading to make apparently scientific claims about reductions in the ecological footprint for those products and practices.
The lifecycle of a car, for example, will include everything from the mining of metal ores and the energy used to process that into steel, to the crushing of the car and smelting the materials back into useful scrap metal.
What is an ecological footprint? A completely different approach is required, more appropriate for products and small communities - you do it "bottom up".
Cropland - subdivided into primary and marginal land e. Global hectares factor in different land types and locations, and average our their biocapacity. Students collect data on the waste produced and the resources consumed in providing energy, water and transportation to and from school.
If the footprint were just measured in hectares, it would be a bit meaningless; if I said "I need 2. Students investigate how the school uses resources and disposes of waste, taking a guided tour of the cafeteria, transportation coordination, boiler rooms, building maintenance, etc.
Footprinting an organisation For organisations such as businesses, the footprint is less clearly defined - where do you draw the boundaries? First, you calculate the yield factor for a particular type of land for a particular country e.
Suddenly, the issues of sustainability and human impact on the planet are very close to home. Traditionally companies are happy to account for the operations and the final product, and increasingly the supply chain, external activities and the product use are accounted for as well.
Because of these limitations, ecological footprinting should be used as one tool amongst many. Thank you for such a thoughtful and thorough presentation.Sweden's Ecological Footprint Ecological Footprint is the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
Knowing about ecological footprints is important because they represent how many hectares it takes to sustain a person, city, country, or any place.
Ecological Footprint calculator schools checklist The Schools Ecological Footprint Calculator measures resource consumption and converts this to the amount of land needed to supply the resources and assimilate the waste generated.
Ecological Footprint 9 F Ecological Footprint What is an Ecological Footprint? An ecological footprint is the measurement system that helps us calculate the human pressure(the human demand) on Earth's mint-body.com calculates what percentage and part of the world we use individually or in groups.
ecological footprint the theoretical measurement of the amount of land and water a population requires to produce the resources it consumes and to absorb its waste, under prevailing technology. reserves. Use of Ecological Footprinting to Determine Sustainability “The ecological footprint (EF) has reached worldwide popularity in the last decade as an interesting environmental indicator, and its applications have been extended to different fields” (Herva et al, ).
There is a short text for students to read on Switzerland's use of ecological footprint to conclude. 3. Graph and Text Analysis_Switzerland' Ecological Footprint_Place and Possibilities_Students can then either work through the questions and activities on Switzerland with the PDF or through the material embedded on the site page.
