Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
The carrying capacity of an environment is the maximum population size of a biological species that can be ... This includes countries with dense populations (such as ...
Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host. [5] A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 9.8 billion people, respectively.
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.
Biocapacity is calculated from United Nations population and land use data, and may be reported at various regional levels, such as a city, a country, or the world as a whole. For example, there were roughly 12.2 billion hectares of biologically productive land and water areas on this planet in 2016.
According to the Global Footprint Network's calculations, currently people use Earth's resources at approximately 171% of capacity. [27] This implies that humanity is well over Earth's human carrying capacity at current levels of affluence. According to the GFN: In 2023, Earth Overshoot Day fell on August 2nd. Earth Overshoot Day marks the date ...
In environmental science, a population "overshoots" its local carrying capacity — the capacity of the biome to feed and sustain that population — when that population has not only begun to outstrip its food supply in excess of regeneration, but actually shot past that point, setting up a potentially catastrophic crash of that feeder population once its food populations have been consumed ...
Tourism carrying capacity (TCC) is an imperfect [1] but useful approach to managing visitors in vulnerable areas. [2]
