Introduction
An ecosystem is a collection of living and nonliving organisms and their interactions with one another. It is a dynamic system made up of both biotic and abiotic elements. The ecosystem’s balance is maintained by these biotic and abiotic interactions. We, as humans, are an essential component of it. The phrase ‘ecosystem services’ refers to the multiple advantages humans receive from the ecosystem.
Ecosystem Services Definition
There are millions of species on the planet that depend on each other in various ways. The interdependence of species and interaction with their environment results in the formation of ecosystems. The interactions between the components of an ecosystem determine the environment.
Humans benefit from the biotic and abiotic components of the ecosystem they inhabit in a variety of ways. Ecosystem services refer to all of these advantages. These services also do the work of protecting biodiversity on Earth. Products like food and water, flood control, soil erosion, and disease outbreaks are some examples of ecosystem services, as are non-material advantages such as recreational and spiritual benefits of natural settings.
Types of Ecosystem Services
Provisioning services
Food, water, medicines, and other ecosystem resources are examples of products, raw materials or energy outputs. Ecosystems provide food, water, medicines, timber, biofuels and other resources. They also create favourable circumstances for the development of these resources.
Regulating ecosystem services
This includes functions that keep the ecological balance in check. Terrestrial habitats such as forests, for example, filter and regulate air quality, prevent soil erosion, and regulate greenhouse gas emissions. Birds, rodents, and frogs, for example, operate as natural controllers and so aid in pest and disease management. As a result, ecosystems serve as regulators.
Regulating ecosystem services are almost unnoticeable operations. Their importance is only revealed when something goes wrong—when there is too much water or when the water is contaminated; when the environment becomes too warm and unpredictable; when fruit harvests fail due to a lack of pollinators.
Many regulatory services are unknown to us. Even our comprehension of basic processes may be lacking, let alone our ability to track their scope and progression in a meaningful manner.
The majority of regulatory services have no market. They have typically been seen as externalities in the economy, not factored into computations. As a result, they have been frequently subjected to the Tragedy of the Commons, which involves individuals diminishing a common resource out of rational self-interest in the absence of a mechanism to govern its usage.
Supporting services
Other services are built on the foundation of supporting services. They support life on the planet by providing habitat for various living forms, preserving biodiversity, nutrient cycling, and other functions. These mechanisms enable the Earth to support even the most basic living forms, much alone entire ecosystems and humans. Provisional, regulating, and cultural services would not exist without supporting services.
Cultural services
Tourism is included, as well as recreational, aesthetic, cultural, and spiritual services. Landscapes, mountains, and caverns are among the most commonly exploited natural features for cultural and artistic reasons. Some of them are even considered sacrosanct. Ecosystems also give significant economic advantages in the form of tourism.
It is hard to put a value on ecosystems and their services. Supporting services alone account for nearly half of all ecosystem services, with the other services accounting for less than ten per cent. The value of ecosystems towards the human mind may be traced all the way back to the dawn of civilization, when ancient civilisations drew animal, plant, and weather patterns on cave walls. A cultural service is a non-monetary advantage that contributes to people’s cultural growth and advancement, such as how ecosystems play a part in local, national, and global cultures.
Points about ecosystem services-
Healthy ecosystems are the base for a wide range of economic, environmental and aesthetic goods and services.
The products of ecosystem processes are named as ecosystem services, for example, healthy forest ecosystems purify air and water, mitigate droughts and floods, cycle nutrients, generate fertile soils, provide wildlife habitat, maintain biodiversity, pollinate crops, provide storage site for carbon and also provide aesthetic, cultural and spiritual values.
Though the value of such services of biodiversity is difficult to determine, it seems reasonable to think that biodiversity should carry a hefty price tag.
Robert Constanza and his colleagues have very recently tried to put price tags on nature’s life-support services. Researchers have put an average price tag of US $ 33 trillion a year on these fundamental ecosystems services, which are largely taken for granted because they
are free.
This is nearly twice the value of the global gross national product GNP which is (US $ 18 trillion).
Out of the total cost of various ecosystem services, the soil formation accounts for about 50 per cent, and contributions of other services like recreation and nutrient cycling, are less than 10 percent each. The cost of climate regulation and habitat for wildlife are about 6 percent each.
Conclusion
People have long acknowledged the importance of nature, but only recently has the idea of ecosystem services been established to represent these varied advantages. Any good advantage that wildlife or ecosystems deliver to people is referred to as an ecosystem service. The advantages might be direct or indirect, and they can be minor or big.
