The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. The carrying capacity is defined as the environment 's maximal load, [clarification needed] which in population ecology corresponds to ...
The ecological footprint measures human demand on natural capital, i.e. the quantity of nature it takes to support people and their economies. [1] [2] [3] It tracks human demand on nature through an ecological accounting system. The accounts contrast the biologically productive area people use to satisfy their consumption to the biologically ...
Overshoot (population) 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 ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic data.
Population geography. Satellite image of Earth at night. Population geography relates to variations in the distribution, composition, migration, and growth of populations. Population geography involves demography in a geographical perspective. [a] It focuses on the characteristics of population distributions that change in a spatial context.
The global hectare is a useful measure of biocapacity as it can convert things like human dietary requirements into common units, which can show how many people a certain region on earth can sustain, assuming current technologies and agricultural methods. It can be used as a way of determining the relative carrying capacity of the earth.
Adaptive capacity in the context of climate change covers human, natural, or managed systems. It looks at how they respond to both climate variability and extremes. It covers the ability of a system to adjust to climate change to moderate potential damages, to take advantage of opportunities, or to cope with consequences.
Ecology is as much a biological science as it is a human science. Human ecology is an interdisciplinary investigation into the ecology of our species. "Human ecology may be defined: (1) from a bioecological standpoint as the study of man as the ecological dominant in plant and animal communities and systems; (2) from a bioecological standpoint ...
