The ecological footprint measures human demand on natural capital, ... It can be calculated at any scale: for an activity, a person, a community, a city, a region, a ...
This is a list of countries by ecological footprint. The table is based on data spanning from 1961 to 2013 from the Global Footprint Network's National Footprint Accounts published in 2016. Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person
The global hectare (gha) is a measurement unit for the ecological footprint of people or activities and the biocapacity of the Earth or its regions. One global hectare is the world's annual amount of biological production for human use and human waste assimilation, per hectare of biologically productive land and fisheries.
Impact may be measured using ecological footprint analysis in units of global hectares (gha). Ecological footprint per capita is a measure of the quantity of Earth's biologically productive surface that is needed to regenerate the resources consumed per capita. Impact is modeled as the product of three terms, giving gha as a result.
Earth Overshoot Day is calculated by Global Footprint Network and is a campaign supported by dozens of other nonprofit organizations. [3] Information about Global Footprint Network's calculations [4] and national Ecological Footprints are available online. [5]
Examples include adjusted net savings (ANS) and ecological footprint accounts. ANS is calculated as the change in total wealth over a given time period, while ecological footprint assessments determine how much of the regenerative capacity of the biosphere is required to maintain the consumption habits of a defined population. [5]
In other words, it is a measure of the ecological efficiency at supporting well-being. [14] [15] Furthermore, the Happy Planet Index was criticized because the used data is not comprehensive enough. In the HPI Report of 2006 (by nef) they emphasized that they "were forced to estimate data on Footprint and life satisfaction for several countries".
Ecological footprint accounting, based on the biological concept of carrying capacity, tracks the amount of land and water area a human population demands for producing the biological resources the population consumes, for absorbing its waste, and for accommodating its built infrastructure, all under prevailing technology.
