El objetivo de esta investigación es discutir y analizar cómo las geo-tecnologías y la disponibilidad de datos geo-referenciados pueden contribuir en la prevención y minimización de catástrofes naturales, tomando como estudio de caso las inundaciones ocurridas en la Provincia de Alagoas, Brasil, en 2010, ubicada en una región con grandes inequidades sociales. Analizaremos el rol de instituciones públicas y privadas en ese proceso, el desarrollo en regiones de capitalismo tardío y los nuevos retos impuestos a las administraciones municipales, principalmente sobre la previsión respecto de mayor severidad y frecuencia de eventos extremos en las zonas tropicales, resultantes de los probables cambios en la dinámica del clima planetario. Por lo tanto es necesario acercarse del marco conceptual que nos brinda la Teoría Social del Riesgo que hoy ocupa un lugar central de las agendas políticas de los gobiernos. Serán abordadas las dimensiones respecto a la peligrosidad, la vulnerabilidad, la exposición y la incertidumbre. Así que esta investigación busca aclarar la situación en la cual se produjo la catástrofe en Alagoas y cómo las geo-tecnologías pueden contribuir a un uso socialmente más amplio para la anticipación, prevención y gestión del riesgo. A B S T R A C T The objective of this research is to discuss and analyze how the geo-technologies and the availability of geo-referenced data can contribute to the prevention and minimization of natural disasters, taking as a case study of flooding in the province of Alagoas, Brazil, in 2010, located in a region with great social inequalities. Analyze the role of public and private institutions in this process, the development in regions of late capitalism and the new challenges posed to local governments, mainly on the provision in respect of greater severity and frequency of extreme events in the tropics, resulting from likely changes in global climate dynamics. Therefore it is necessary to approach the conceptual framework that gives us the Social Theory of Risk now occupied a central place in the political agendas of governments. Dimensions will be addressed regarding the hazard, vulnerability, exposure and uncertainty. So this research seeks to clarify the situation in which the disaster occurred in Alagoas and how geo-technologies can contribute to a broader social anticipation, prevention and risk management.
