Geoconservação da formação ipu: inventário e diretrizes para proteção dos sítios paleontológicos

Abstract

The paleontological sites of the Ipu Formation, part of the Serra Grande Group of the Parnaíba Basin, hold high scientific and educational relevance but face threats from anthropogenic degradation, lack of conservation policies, and limited recognition by local communities and public administrators. This study conducted an inventory of these sites to propose geoconservation strategies aimed at their protection and valorization, integrating paleontological heritage preservation with sustainable development. A bibliographic review, geological map analysis, and preliminary fossil site identification were carried out. The sites were then characterized in the field through georeferencing, geological description, vulnerability analysis, and conservation status assessment. A quantitative evaluation was performed using the GEOSSIT platform to determine scientific value, degradation risk, and educational and touristic potential. Nine sites were inventoried across four municipalities in northwestern Ceará, with the Zipu and Contra Fogo sites in Pacujá standing out due to their high scientific and educational relevance but also their vulnerability. In response to the identified threats, specific geoconservation guidelines were proposed for Pacujá, including the integration of territorial planning, environmental education, and geotourism. These initiatives involve training local tour guides, creating a tour guide association, and establishing partnerships with schools and universities. It is suggested that these guidelines be replicated in other municipalities within the study area to expand the positive impacts of geoconservation. The study concludes that integrating geoconservation into territorial planning is essential for preserving paleontological sites, enhancing their scientific, cultural, and economic value, and strengthening local communities.
