Ecosystems are natural capital, the biotic and abiotic benefits that people obtain from their environment, animals, plants, soils, and micro-bacteria.
Micro-bacteria in marine ecosystems, for example, produces breathable oxygen. Plants and soils help regulate climate by capturing carbon dioxide in the air and storing it underground. Wetlands reduce flooding risks in coastal territories. Medicines are extracted from plants like sage, ginger, turmeric, and aloe vera. Animals are hunted for food.
The 2006 Millennium Ecosystem Assessment (MA) outlined four distinct categories of ecosystem services to help map the different kinds of benefits provided to human populations. The categories can help us identify what advantages are gained by people and suggest the value of the service. Though it can be difficult to put a price on nature’s contributions, estimates are somewhat determined by the service’s utility, either for humanity, other species, or the ecosystem itself. Categorizing ecosystem services can inform policy and be implemented in conservation research.
Four Types of Ecosystem Services
There are four main types of ecosystem services: provisioning, regulating, supporting, and cultural. Each one of these classifications describes unique outputs made possible by ecological systems. A single ecosystem may produce multiple types of services at once.
Provisioning ecosystem services are the substantive, or material benefits from an ecosystem. This type of service includes raw materials like wood, fresh water, metals, and medicinal herbs. Foods too are provisioning services that are grown on farms, synthesized from natural ingredients, or extracted from animals.
Regulating ecosystem services are sometimes called managing services. These services govern the cycles within an ecosystem. Regulating services play essential roles in managing the water cycle, the carbon cycle, soil quality, crop pollination, and water purification. Regulating services are those that moderate climate and the intensity and frequency of weather events.
The natural processes within ecosystems are part of the ecosystem’s own continued survival and maturity. As ecosystems mature, they can grow more complex, support greater profiles of species richness and allow novel interactions between organisms to develop. Supporting services refer to an ecosystem’s capacity to keep itself functioning over time.
Cultural services are the nonmaterial contributions that we derive from the natural world. Around the world, people rely on nature for their sense of cultural identity, including art, architecture, and recreation.
One thought on “Ecosystem Services”
Very nice article. I think it is pieced together very well
