Ecosystem services: An economic value
In the 21st century, the well-being of our environment has become one of the core issues. We value the environment for different reasons, some appreciate its aesthetic beauty, others recognize its invaluable scientific value. However, it has become increasingly clear that natural ecosystems also provide economic value that is often overlooked. These economic benefits are referred to as ecosystem services.

Ecosystem services: An economic value
In the 21st century, the well-being of our environment has become one of the core issues. We value the environment for different reasons, some appreciate its aesthetic beauty, others recognize its invaluable scientific value. However, it has become increasingly clear that natural ecosystems also provide economic value that is often overlooked. These economic benefits are referred to as ecosystem services.
What are ecosystem services?
Ecosystem services are the diverse benefits that humanity receives from the mere existence and continuation of natural ecosystems. They are important components of our social and economic well-being and influence our survival and material prosperity. They cover areas such as drinking water treatment, pollination of crops, climate regulation and recreational values.
Classification of ecosystem services
Ecosystem services are divided into four main categories:
- Erbringungsleistungen, die die direkte Nutzung von Ökosystemressourcen, wie Nahrung oder Bauholz, umfassen.
- Regulierungsleistungen, die Veränderungen im Ökosystem umfassen, die positiv auf das menschliche Leben einwirken, wie die Klimaregulierung oder die Einfluss auf natürliche Gefahren.
- Unterstützungsleistungen, die grundlegende Ökosystemprozesse wie Bodenbildung und Nährstoffkreisläufe fördern.
- Kulturelle Leistungen, die nicht materielle Vorteile, wie ästhetische Inspiration, Erholung und spirituelle Erfahrung umfassen.
The economic value of ecosystem services
Quantifying the value of ecosystem services is a complex task. Many of these services are often viewed as "free" because they are not traded on conventional markets. However, they have an absolute economic value that we must begin to recognize and integrate if we truly want to limit the harmful effects of our actions on the environment.
The ability of ecosystems to provide invaluable services can be significantly compromised if they are overexploited or destroyed. Therefore, quantifying their value can be an effective tool for conservation and improved management of these resources.
Monetary valuation of ecosystem services
One way to determine the economic value of ecosystem services is to estimate their monetary valuations. This can be done through various methods such as cost avoidance approaches, replacement cost methods, production functions and welfare economics approaches.
A famous example of this is the study by Robert Costanza et al. in 1997, in which they estimated the total value of ecosystem services provided by Earth at $33 trillion per year. This is more than double the global gross national income at that time.
The benefits of considering ecosystem services in management
Taking ecosystem services into account in management decisions has a number of benefits. It helps us recognize and evaluate the full impact of our actions on the environment and human well-being. It also supports a better balance between the short-term consumption of resources and their long-term preservation for future generations.
Application examples
There are many examples of successfully integrating ecosystem service valuation into decision-making. A particularly clear case is New York's water supply.
Instead of spending billions of dollars to build and operate water filtration plants, the city of New York has instead invested in protecting and improving watersheds in the Catskill and Delaware Mountains. This allowed them to utilize the ecosystem services provided by these natural areas to provide fresh, clean water at a significantly lower cost. A win-win situation for both nature and people.
Conclusions
It is clear that ecosystem services make up a significant part of our economy, although they are not measured in traditional ways. Recognizing these services and their importance to our social, economic and environmental well-being is an important step in improving our relationship with the natural world.
Promoting more sustainable use of ecosystem services and reducing our impact on the environment will also help ensure the survival of the human race and the stability of our societies. This shift requires a change in our mindset and a greater engagement with the natural world, which will ultimately benefit us all.
Overall, ecosystem services provide invaluable benefits that are invisible in the market, and their value should be taken into account when developing economic and environmental policies.
