What Does Economic Valuation of Ecosystem Services Mean?
Imagine being able to assign a monetary value to the benefits we receive from the services provided by the environment, such as enjoying the imposing Andean landscapes or clean air thanks to carbon capture by forests and oceans. Although these services are not traded in a traditional market, their importance is undeniable for our well-being and enjoyment. This is where the Economic Valuation of Ecosystem Services comes in, a process that seeks to estimate in monetary terms the value of those environmental goods and services that are often invisible in conventional economic transactions.
Why is it Important?
This is not just an academic exercise; it’s a tool for decision-making and planning of projects and sustainable policies. By assigning a monetary value to these goods and services provided by nature, from the preservation of a landscape to the consequences of water and air pollution, the economic valuation allows us to weigh the costs and benefits of various actions, projects, or policies in a way that is comprehensible and more tangible for all stakeholders involved.
How is an Economic Valuation Analysis done?
There are two main approaches to conducting an economic valuation:
- When market prices exist: This is more straightforward, as existing prices can be used to estimate the value of environmental impacts.
- When market prices do not exist: Here it becomes more challenging, requiring indirect and creative methods to estimate value, such as surveys to understand people’s willingness to pay to conserve a natural resource or to avoid environmental damage.
A particularly useful technique in situations without market prices is “benefit transfer,” which allows us to estimate the value of an environmental good or service based on previous studies of similar situations. This type of method is often referred to in the development of Environmental Impact Assessments (EIA).
Final Notes
The inclusion of economic valuation in EIAs of projects is not only good practice but a necessity. It provides us with a clear indication of the magnitude of how a project will affect society, for better or worse. This information is important for stakeholders and decision-makers, helping them to choose projects that are beneficial in the long term for society and the environment.
The economic valuation of ecosystem services offers us a way to recognize and quantify the value of the services that the environment provides us. In a world focused on making efforts to face environmental challenges, tools like economic valuation are essential to guide our decisions towards a more sustainable future.
