At a global scale, footprint assessments show how big humanity's demand is compared to what Earth can renew. Global Footprint Network estimates that, as of 2022, humanity has been using natural capital 71% faster than Earth can renew it, which they describe as meaning humanity's ecological footprint corresponds to 1.71 planet Earths.
Every year, Global Footprint Network produced a new edition [3] of its National Footprint and Biocapacity Accounts, which calculate Ecological Footprint and biocapacity of more than 200 countries and territories from 1961 to the present. Based on up to 15,000 data points per country per year, these data have been used to influence policy in ...
Numbers are given in global hectares per capita. The world-average ecological footprint in 2016 was 2.75 global hectares per person (22.6 billion in total). With a world-average biocapacity of 1.63 global hectares (gha) per person (12.2 billion in total), this leads to a global ecological deficit of 1.1 global hectares per person (10.4 billion ...
Each country's HPI value is a function of its average subjective life satisfaction, life expectancy at birth, and ecological footprint per capita. The exact function is a little more complex, but conceptually it approximates multiplying life satisfaction and life expectancy and dividing that by the ecological footprint.
Lighter shades denote countries with a lower ecological footprint per capita and darker shaded for countries with a higher ecological footprint per capita. The total ecological footprint (global hectares affected by humans) is measured as a total of six factors: cropland footprint, grazing footprint, forest footprint, fishing ground footprint ...
This ecological debt is often referred to as our global 'ecological overshoot'. The data from the Global Footprint Network has been used to create the graph below, it shows that since the 1970s the global population is increasingly compromising the Earth's ecosystem. The red section of the graph indicates that the global population have been ...
Biocapacity is used together with ecological footprint as a method of measuring human impact on the environment. Biocapacity and ecological footprint are tools created by the Global Footprint Network, used in sustainability studies around the world. Biocapacity is expressed in terms of global hectares per person, thus is dependent on human ...
The Human Footprint increased by 9% from 1993 to 2009, at least partly attributable to a human population increase of 23% and a global economy increase of 153% during the same period. [3] Though population and economic growth far exceed the growth of the Human Footprint, the areas that saw increased human influence were those with the highest ...
