Assessing Climate Change Threats to the Marine Environment: An Application of the Ordered Logit Model
Yeong Nain Chi
ABSTRACT
This study explores saltwater anglers’ perceptions of climate change threats to the marine environment, drawing on data from the 2013 National Saltwater Angler Survey. A multi-attribute framework is employed, and an ordered logit model is used to analyze responses captured on a Likert-type scale, which measures the perceived threat on a continuum from low to high. The empirical findings indicate that demographic factors, such as age, gender, income, education level, and geographic region, significantly shape anglers’ concerns regarding climate change impacts on marine ecosystems. Older anglers, for example, may perceive the threat differently compared to younger ones, while regional variations highlight diverse environmental awareness across the country. These results offer valuable insights into how saltwater anglers view marine environmental risks linked to climate change. The findings provide a foundation for designing more targeted marine fisheries management and communication campaigns that address specific demographic groups’ concerns about climate-driven environmental changes.
