Methodology for the Semi-quantitative Evaluation of Geoheritage Applied to Coastal Geotourism in João Pessoa (Paraíba, Northest Brazil)

Abstract

In this work, a new methodology is presented for the semi-quantitative evaluation of the coastal geotouristic potential and protection requirements of ten sites chosen in the coastline of the State of Paraíba, about 54 km from the state capital. The geotouristic potential was determined based on two indicators, whose value was estimated: the Touristic Use Potential, with ten variables, with different levels of importance, and the Additional Value, with six variables, also with different levels of importance. The Need for Protection Index was estimated taking into consideration ten variables with different levels of importance and based on the need to protect the sites once the geotouristic activity starts to generate impact in the places where it is implemented. The Imminent Risk Index applied to the sites where the level of vulnerability is greater was calculated based on the Need for Protection Index, with a weight of 1, and the Touristic Use Potential and Additional Value Index, which added also present a weight of 1. The result of the simulation done to the area was satisfactory, making it possible to apply in other areas, as long as the necessary adjustment measures to the local context are taken into consideration.
