ABSTRACT
The Carnaubais municipality, located in the state of Rio Grande do Norte State, Brazil, has recurring problems of flood
events, causing economic, social and environmental impacts in local, regional, national, and international scale,
because its economy is focused on oil production and fruit cultivation for export. Over the years it has been seen that
such events have occurred at shorter intervals and with greater impacts caused. Due to these impacts, it was necessary
to study the environmental, social and managerial dynamics of this municipality. This article aims to identify the best
option within the established alternatives to assist in determining priorities for flood risk management in the municipality.
The used methodology was the Analytic Hierarchy Process (AHP), with the use of four indicators for the disasters
preparedy by Cardona et al. (2005): Risk Identification, Risk Reduction, Disaster Management, and Governance and
Financial Protection. Those indicators were selected according to the judgments issued by the municipal civil defense
coordinator. According to the main results from AHP for Risk Identification, should be prioritized for implementation, in
descending order: monitors of threats and prognosis (29,6%); public information and community participation (22,4%);
and, systematic inventory of disasters and losses (19,3%). For Risk Reduction: integration of risk in defining land use
and urban planning (35,7%); intervention and environmental protection of river basins (19,2%). For Disaster
Management: organization and coordination of emergency operations (35,2%); preparation and training community
(17,2%); and, response planning in emergency case and warning systems (16,9%). And for Governance and Financial
Protection: interagency organization, of multiple sectors and decentralized (28,7%); location and resource mobilization
and budget (20,7%); and, network deployments and social security funds (15,9%). From the results obtained, it is
concluded that the sequence established by the methodology should be implemented by public managers, to have a
flood risk management more efficient in the municipality.
