Valoração ambiental: aplicação do método de experimento de escolha discreta (DCE) na área da praia de Maracaípe, Ipojuca, Pernambuco

Abstract

Coastal urbanization has intensified in recent decades, driven by economic development and population growth, but also bringing environmental and social challenges. This study aimed to assess the perception and economic value of different attributes of Maracaípe beach, in Ipojuca, Pernambuco. A discrete choice experiment was used to analyze the attributes of building height, beach occupancy, setback from the shoreline, and the Willingness to Pay (WTP) rate. A total of 261 questionnaires were applied between September and December 2024, with hypothetical scenarios to understand the participants' preferences. The analysis was conducted using Artificial Intelligence software, applying logistic regression to explore multiple variables. The results indicated that an increase in beach occupancy had a positive effect on the choice, while an increase in building height and setback from the shoreline had negative effects, with varying statistical significances. The WTP was positive for building height (R$11.13) and setback (R$62.88), but negative for occupancy. It was concluded that the method can be a valuable tool for environmental management, promoting a participatory process between the public authorities and population.
