Question
Valuation of the environmental amenities is crucial for decision making. However, it is very difficult to come up with a value for clean air, sunshine, clear water and so forth. But we still need some numbers for their values to help with decision making. This is where the willingness to pay (WTP) and willingness to accept (WTA) concepts of valuing the environment amenities are crucial in order to obtain some values for them. Use the equation for the calculation of the total value of willingness to pay (WTP) to discuss how the value of air should be estimated. You must use a numerical example to support your answer. Proper referencing of sources used to help in the writing up must be displayed.
Explanation / Answer
How the value of air should be estimated given below: Introduction-
Explanation-
Example:
In the U.S., this is a number between 0 to 500, for the new China air quality index this is also a number between 0 to 500. Cities in China that have not adopted the AQI, still use API to measure china air quality on a scale of 0 to 300.
if measurements for Beijing air quality show that PM2.5 has an AQI of 150 and all other pollutants report lesser than 150, then the AQI will be based on the PM2.5 levels.
Equation:
{the below equation is just an example, not real }
Suppose to know the level of air quality we could express that in this form-if index is
~"equal to pm 0" -no problem,
~"greater than pm 0 but less than pm 5.0"- small problem
~"greater than pm 5" - huge problem.
As I said in above example ,let us see what will the concerned government do if index shows unfavorable indication:
When air quality indices record high levels, government agencies deal with such instances through any of the following ways:
Summary:
Though countries in creating their pollution indices adhere to WHO guidelines, a lot of them base their pollution index decisions on local needs. The WHO Air Quality Guidelines (released in 1987, with subsequent updates in 1997 & 2005), are not significant from a legislative point of view, but are instead meant to advice policy.
