The biocapacity or biological capacity of an ecosystem is an estimate of its production of certain biological materials such as natural resources , and its absorption and filtering of other materials such as carbon dioxide from the atmosphere. [1] [2] „Useful biological materials“ are defined as those of the human economy.

Biological capacity per person: There were 12 billion hectares of biologically productive land and water on this planet in 2008. Dividing by the number of people living in that year, 6.7 billion, gives 1.8 global hectares per person. This assumes that no land is set aside for other species that consumes the same biological material as humans. [3]

Applications of biocapacity

An increase in global population can result in a decrease in biocapacity. This is usually due to the fact that the Earth’s resources have been shared; therefore, there becomes little to increase the population of the population . [4]Currently, this issue can be resolved by outsourcing . However, the results of this study are likely to be increased as a result of the collapse of an ecosystem. [4] When the ecological footprint becomes greater than the biocapacity of the population, a biocapacity deficit is suspected. [5]‚Global biocapacity‘ is a term sometimes used to describe the total capacity of an ecosystem to support various continuous activity and changes. When the ecological footprintof a population exceeds the biocapacity of the environment, it can be called an ‚ecological overshoot‘. [5] [6] A 2008 report stated that people were using an equivalence of 1.5 Earths to compensate for their needs. [4] However other sources have suggested that depletion of cropland, grazing land, forest land, fishing grounds, and built-up land is not occurring on an aggregate, global level. Hence, virtually all of the ecological overshoot comes from the extent of the carbon dioxide is accumulating in the atmosphere. [7]Additional stresses of greenhouse gases , climate change , and ocean acidification can also aggravate the problem. [4] In reference to the definition of biocapacity: 1.5 Earths means clustering renewable resources will result in depletion Eventually Because They Are Produced being white Often faster and more than the resources can be re-grown. [4] Therefore, it will be one year and six months for the resources we use to be able to regenerate again and more. [4] So instead of taking one year, we are now in-taking enough resources that should last one year and six months.

In addition, this issue becomes severe, an ecological reserve will be set to areas to preserve their ecosystems. Awareness about depleting resources include: agricultural land, forest resources and rangeland. [8] Biocapacity used in correlation to ecological footprint can therefore be a specific population, region, country or part of a world is living in the means of their capital. Accordingly, the study of biocapacity and ecological footprint is known as the Ecological Footprint Analysis (EFA) . [1]

Biocapacity is also affected on the technology used during the year. With new technologies emerging, it is not so much the technology that it is good or bad. which in return affects biocapacity. [1] Hence, what is considered „useful“ can change from year to year (eg use of corn (maize) stover for cellulosic ethanol production would result in becoming a material, and thus increase the biocapacity of maize cropland).

Moreover, environmentalists have created ecological footprint calculators for a single person (s) to determine whether they are encompassing more than what is available for them in their population. [9] Consequently, biocapacity results will be applied to their ecological footprint to determine how much they will contribute to sustainable development.

In general, biocapacity is the amount of a specific population in a specific population ( supply ) and to differentiate between ecological footprint – that is the demand for a regional ecosystem . [9] Biocapacity is able to determine the human impacts on Earth. By calculating productivity, the resources available for human consumption, it is possible to predict and estimate the effects on the ecosystems. The biocapacity of an area is calculated by multiplying the yield factor and the appropriate equivalence factor. Biocapacity is usually expressed in global hectares (gha). [10] Since global hectares are able to convert human consumption and water into a measurement, biocapacity can be applied to the carrying capacity of the Earth.
