The term carrying capacity has been applied to a few different processes in the past before finally being applied to population limits in the 1950s. [1] The notion of carrying capacity for humans is covered by the notion of sustainable population.
Wackernagel and Rees originally estimated that the available biological capacity for the 6 billion people on Earth at that time was about 1.3 hectares per person, which is smaller than the 1.6 global hectares published for 2024, because the initial studies neither used global hectares nor included bioproductive marine areas.
This issue is important if the source–sink concept is viewed in terms of habitat quality (as it is in Table 1) because classifying high-quality habitat as low-quality may lead to mistakes in ecological management. Runge et al. [9] showed how to integrate the theory of source–sink dynamics with population projection matrices [10] and ...
These terms, r, and K, are derived from standard ecological algebra, as illustrated in the simple Verhulst equation of population dynamics: [30] = where r is the growth rate of the population (N), and K is the carrying capacity of its
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 maximum endurable impact is called the carrying capacity. As long as "I" is less than the carrying capacity the associated population, affluence, and technology that make up "I" can be perpetually endured. If "I" exceeds the carrying capacity, then the system is said to be in overshoot, which may only be a temporary state. Overshoot may ...
In a population, carrying capacity is known as the maximum population size of the species that the environment can sustain, which is determined by resources available. In many classic population models, r is represented as the intrinsic growth rate, where K is the carrying capacity, and N0 is the initial population size.
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.
