Protocolo de base de dados para valoração ambiental de atrativos da Chapada Diamantina

Abstract

This work presents the development of a methodological protocol for the economic valuation of tourism in the Chapada Diamantina National Park (PNCD), filling the gap of financial decision support instruments in the unit. The main objective was to structure a discrete choice experiment (DCE) capable of measuring visitors' willingness to pay for specific management attributes, while also seeking to capture the effect of non-use values. The methodology consisted of applying D-Efficiency theory to generate a pilot experimental design in the R environment, resulting in a matrix with 16 choice sets divided into two blocks. The design integrated five attributes of interest—access difficulty, infrastructure, conservation, crowding, and cost—and proposes data collection via the digital platform of a local operator (Janoo). The results indicated a statistically efficient design (D-Error of 1.11) with null priors, qualitatively validated to capture non-linear preferences. It is concluded that the established protocol offers a robust basis for the future estimation of econometric models, allowing managers to decompose the economic value of the park and simulate public policy scenarios based on demand evidence.
