DRM event highlights need for unified database for risk analysis

Brazil: Lack of a unified database that brings together geological information and analysis of landslide risks in Brazil is identified as one of the major obstacles in development of more efficient policies to prevent natural disasters in the country. Keeping this in mind, the Geological Survey of the State of Rio de Janeiro (DRM-RJ) is studying the implementation of a system of georeferenced database in the state. The Center for Analysis and Diagnosis Landslides (NADE / DRM-RJ) organised an event, Structure and accessories for a database specifically aimed for risk analysis of landslides in Rio de Janeiro, on April 25, for DRM officials, agents of civil defense, firemen and workers from the city hall to disseminate knowledge about different proposals and georeferenced databases existing in Brazil.

Among the initiatives, the Geological Survey of Brazil presented the Registration System of Landslides and Floods (SCDI). The platform acts as an inventory that collects and standardises information on events, or potential events, related to landslides and floods in the country. The system has been implemented in three states and it is now training users in several Brazilian cities.

Another project presented was the platform GEORISC – Computer Engineering Applied to Geo-environmental Risks, coordinated by the Pontifical Catholic University of Rio de Janeiro (PUC-Rio). Through a cadastre of geological information and a collaborative system, the system allows users to develop different maps that aim to analyse, quantify and predict risk geo-environmental condition.

The purpose of DRM, in the future, is to implement a database that will combine geological knowledge with different risk landslide scenarios for help decision makers.
