What is the total economic value of an ecosystem?
The concept of total economic value (TEV) of ecosystems and biodiversity is used thoughout this chapter.
It is defined as the sum of the values of all service flows that natural capital generates both now and in the future – appropriately discounted..
What is diversity in an ecosystem?
Ecological diversity includes the variation in both terrestrial and aquatic ecosystems. Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of trophic levels and other ecological processes.
What are the six values of biodiversity?
This article throws light on the six major values of biodiversity. The six major values are: (a) Total Environmental Value (TEnV), (b) Primary Value (PV), (c) Total Economic Value (TEV), (d) Use Value (UV), (e) Direct Use Value (DUV), (f) Indirect Use Value (IUV), and (g) Ethical and Aesthetic Values.
Is biodiversity a good or bad thing?
They supply us with oxygen and clean water. They cycle carbon and fix nutrients. They enable plants to grow and therefore to feed us, keep pest species and diseases in check and help protect against flooding and regulate the climate. These benefits are known as ecosystem services.
What are the social values of biodiversity?
The social value of biodiversity includes aesthetic, recreational, cultural and spiritual values. To this can be added health benefits resulting from recreational and other activities.
What is direct use value?
(of Ecosystems) The economic or social value of the goods or benefits derived from the services provided by an ecosystem that are used directly by an economic agent. These include consumptive uses (e.g., harvesting goods) and non-consumptive uses (e.g., enjoyment of scenic beauty).
What are the 3 values of biodiversity?
The individual components of biodiversity—genes, species, and ecosystems—provide society with a wide array of goods and services. Genes, species, and ecosystems of direct, indirect, or potential use to humanity are often referred to as “biological resources” (McNeely and others 1990; Reid and Miller 1989; Wood 1997).
What is value of biodiversity?
Biodiversity has a fundamental value to humans because we are so dependent on it for our cultural, economic, and environmental well-being. … Biodiversity forms the backbone of viable ecosystems on which we depend on for basic necessities, security, and health.
What are the main factors in ecosystem diversity?
Broadly speaking, the diversity of an ecosystem is dependent on the physical characteristics of the environment, the diversity of species present, and the interactions that the species have with each other and with the environment.
How do you calculate total economic value?
Total Economic Value (TEV) is the sum of all benefits obtained from a resource. = Use Value + Non-Use Value [We include option value under “non-use value” to distinguish it from existing/current “use values”.]
What are the threats to biodiversity?
Threats to BiodiversityHabitat Fragmentation. Ecosystem conversion and ecosystem degradation contribute to habitat fragmentation. … Exotic Species Introductions. Infestation by alien species, such as the Codling Moth, is also a major threat to BC ecosystems. … Pollution. … Global Climate Change. … Corridors and Connectivity.
What are indirect values of biodiversity?
Three Indirect Values: Social and cultural values are an indirect value to biodiversity because in some religious countries many plants and animals are considered sacred and holy and are worshipped and respected.
What is the difference between direct and indirect use value of biodiversity?
Direct use value of biodiversity is every living organism has an important rules for sustainability and nourishment of nature and ecosystem. … Indirect use value of biodiversity is that every living organism is dependent on other organisms indirectly.
What is direct use value of biodiversity?
Direct values include the ways in which biodiversity is used or consumed by man e.g. fishery and forestry products, as well as the ways in which it affects mankind through its ecological processes e.g. watershed protection or the role of vegetation in the carbon and water cycles.
What is the difference between direct and indirect economic value?
Answer: The direct value of biodiversity involves the direct economic value of the products that are sold, while indirect economic value involves intrinsic value. The direct value of biodiversity is directly harvested from an organism. Example of the direct economic value of diversity includes making food, medicine.
