List of countries by ecological footprint - Wikipedia
The Ecological Footprint (EF) is one part of a renewable resource accounting tool that is The mathematical difference between EF and BC is called either reserve (Global. badz.infok)badz.info,badz.info To live within the means of our planet's resources, the world's Ecological Footprint would have to equal the available biocapacity per person on our planet, which. The amount of biocapacity set aside to maintain representative ecosystem . The difference between the biocapacity and Ecological Footprint of a region or.
Similarly, minerals are limited by the energy available to extract them from the lithosphere and concentrate them. The limits of ecosystems' ability to renew biomass is given by factors such as water availability, climate, soil fertility, solar energy, technology and management practices.
- Ecological footprint
This capacity to renew, driven by photosynthesis, is called biocapacity. Per capita ecological footprint EFor ecological footprint analysis EFAis a means of comparing consumption and lifestyles, and checking this against biocapacity - nature's ability to provide for this consumption. The tool can inform policy by examining to what extent a nation uses more or less than is available within its territory, or to what extent the nation's lifestyle would be replicable worldwide.
The footprint can also be a useful tool to educate people about carrying capacity and overconsumptionwith the aim of altering personal behavior.
Biocapacity - Wikipedia
Ecological footprints may be used to argue that many current lifestyles are not sustainable. Such a global comparison also clearly shows the inequalities of resource use on this planet at the beginning of the twenty-first century. Inthe average biologically productive area per person worldwide was approximately 1.
The world-average ecological footprint in was 2. The increase of biocapacity averaged at only 0.

Because of agricultural intensification, biocapacity was at 9. InEarth Overshoot Daythe date where humanity has used more from nature then the planet can renew in the entire year, was estimated to be August 1 . This means their ecological footprint for consumption exceeds the biocapacity of that country.
Despite being populated by relatively "mainstream" home-buyers, BedZED was found to have a footprint of 3. The report did not measure the added footprint of the 15, visitors who have toured BedZED since its completion in Findhorn Ecovillagea rural intentional community in MorayScotlandhad a total footprint of 2. However, the residents alone have a footprint of 2.
However this should not be surprising, since the two methods address different research questions. Newman has argued that the ecological footprint concept may have an anti-urban bias, as it does not consider the opportunities created by urban growth.
New York and Singapore respectively — may lead to the perception of these populations as "parasitic". This is because these communities have little intrinsic biocapacity, and instead must rely upon large hinterlands. Critics argue that this is a dubious characterization since mechanized rural farmers in developed nations may easily consume more resources than urban inhabitants, due to transportation requirements and the unavailability of economies of scale. If a country does not have enough ecological resources within its own territory to cover its population's footprint, then it runs an ecological deficit and the country is termed an ecological debtor.
Otherwise, it has an ecological reserve and it is called a creditor. Otherwise all the natural capacities and reserves of earth will once be used and cause a collaps and catastrophy.
There are three ways to achieve this: Increase the biocapacity Decrease the ecological footprint Population policy Assuming biocapacity and ecological footprint will stay the same when population changes, the difference between biocapacity and ecological footprint multiplied with the actual population will result in the population where biocapacity equals the ecological footprint.
In this will be 1. In fact it can be higher because biocapacity in global hectares per capita will increase when population shrinks. To achieve this balance will take generations and to force it for example with one child policy is not a good option. Better is education to give people a perspective and better job opportunities.
The population in many industry countries is also overaged but to solve this problem with more children will cause problems for them when they get old themselves and need even more children to supply them. On an earth with limited space and resources the system with many young people taking care of fewer old will not work forever and endless physical growth is not possible. So there will be a time when more older than young people will live on earth.
