“…In one recent study, I worked with other researchers to estimate increased travel and time expenditures that people incurred to avoid trash and debris on 31 Southern California beaches. No one wants to go to a beach littered with hypodermic needles, plastic bottles and discarded fishing nets. But cleaning up marine debris is expensive, and it is hard for communities to recover the costs, particularly for public beaches with open access. Understanding the value of cleaner beaches can help build support for funding trash collection.
To measure the amount of debris, we hired workers to walk the beaches tallying quantities of trash. Then we surveyed Southern California residents about how often and where they went to the beach, which enabled us to correlate numbers of visitors at each beach with quantities of debris. Finally, using travel time and expenses for each visitor to visit each beach, we modeled the relationship between where they chose to go to the beach, how much they spent to get there, and the cleanliness of the beach.
Using this model, we found that visitors to these beaches would be willing to incur $12.91 in additional costs per trip if each of the beaches had 25 percent less debris. This translated into a total willingness to pay $29.5 million for action to reduce marine debris by 25 percent on these beaches…”
