Economicshelpdesk.com MICROECONOMIC APPROACHES TO VALUING ECOSYSTEM SERVICES Pricing the Priceless
Thinking about nature brings important aspects such as beauty and importance to mind. However, how can we ascribe value to things such as air, water, or even protection of forests against climate change? Such benefits, known as ecosystem services, are crucial for our well-being but they do not come with any price tags. Economics could provide analytical tools that would help us to value these 'priceless' resources, and, in turn, make better decisions for the planet and the economy. INTRODUCTION Economicshelpdesk.com
WHAT ARE ECOSYSTEM SERVICES? Ecosystem services are fundamental benefits derived from Nature. They are categorized into four learned sections: 1. Provisioning services include food, water, timber. 2. Regulating services include air purification, carbon storage, and flood mitigation. 3. Cultural services include recreation, tourism, and spiritual values. 4. Supporting services such as soil formation and nutrient cycling, which make other services possible. Though we may not be conscious of them, these services are an essential part of our lives- from trees in parks providing shade to cleaning air to increasing real-estate values. Because these services are not exchanged on the market, their contribution is usually ignored or undervalued in decisions around economics.
WHY PUT A PRICE ON NATURE? Valuing ecosystem services is not about turning nature into a commodity. It is all about recognizing nature’s contributions. When ecosystems are undervalued, they become more vulnerable to damage or destruction. For example, logging a forest seems profitable as long as one counts only the market value of the timber. Add conceptualizations of the role played by the forest in preventing soil erosion and storing carbon and supporting biodiversity, and then the economic picture will change dramatically. Microeconomics provides us methods to quantify, evaluate, and incorporate these values into decision-making. The quantification is imperfect, and many feel nature’s worth cannot be converted to monetary terms. But the results could go a long way toward protecting the environment even when approximate values are taken into account.
TOOLS FOR ESTIMATING THE VALUE OF ECOSYSTEM SERVICES 2. Hedonic Pricing : This procedure is often utilized in valuing cultural or aesthetic services. For example, homes near parks or beaches tend to render a fairly good price. By comparing property prices in selected locations, economists ascertain how much individuals would be willing to pay to gain or preserve access to such natural amenities. 1. Market-Based Valuation : Market-priced services like fish or timber lend relative ease to value estimation. Economists determine the contributions of these resources to the economy using market prices and quantities. 3. Contingent Valuation : Contingent valuation is the process of asking people how much they would be willing to pay to either protect or restore an ecosystem service. This method is usually instituted for kinds of services where market values are unclear, such as for endangered species or idyllic landscapes. Economicshelpdesk.com
TOOLS FOR ESTIMATING THE VALUE OF ECOSYSTEM SERVICES 5. Travel Cost Method : This is a common approach used to value recreational and cultural services. By examining expenditures that people incur to visit a particular national park or natural site, economists can derive values for such areas. This includes costs like travel, lodging, and entrance fees. 4. Replacement Costs : Sometimes values of ecosystem services may be deduced by what the replacements would cost by way of human-made substitutes. If one were to destroy wetlands, which control floods, for example, how much in levees, etc., would it cost to provide a functionally similar service? Economicshelpdesk.com
REAL-WORLD APPLICATIONS Assessment of ecosystem services is not a mere academic exercise, but has a real-world implications. Such methods are being put to use by several governments and organizations in shaping their policies and investment decisions. For example, instead of spending for a very expensive water filtration plant, New York City opted to protect its watershed. The city wanted to invest money in a scheme to build artificial filtration works; some people pointed out that healthy forests and wetlands were doing the job and at far less cost. Considerable money was thereby saved while, at the same time, the ecosystem was preserved. Thesecond example is from coastal zones where mangroves and corals act as a barrier against storms and floods. The research also revealed that hurricanes are very expensive to communities when the natural barriers are damaged, and the cost of rehabilitating such ecosystems is usually low compared to the cost of hurricanes.
CHALLENGES AND LIMITATIONS Although valuation methods are helpful but they are not perfect. Ecology is very complex and highly qualitative. Individuals (use-diverse) may perceive the information about the same single ecosystem differently based on their culture, ethnic background or experiences. Moreover, there remains the probability of oversimplifying the values or misusing them. For example, if policymakers aim their attention solely on those services with large monetary values, they will fail to address other aspects of ecosystems that are harder to quantify.
