A cidade de Natal apresenta diversas ?reas de riscos, principalmente nas periferias da cidade, devido ? ocupa??o de espa?os que apresentam limita??es legais e/ou f?siconaturais, bem como a falta de organiza??o urbana, aumentando assim, a vulnerabilidade da popula??o que reside nestas ?reas. O objetivo principal desta pesquisa foi mapear as ?reas de vulnerabilidade social e os riscos naturais na cidade de Natal, levando-se em considera??o as inter-rela??es entre as vulnerabilidades sociais e a exposi??o diferenciada aos riscos naturais. Para tanto, foi necess?rio estabelecer, segundo a metodologia utilizada, o grau de vulnerabilidade social e de vulnerabilidade ao perigo natural no qual os indiv?duos est?o sujeitos; visando estabelecer a rela??o sociedade/ riscos. Neste caso, foi utilizada a metodologia proposta por Crepani (2001) que se baseia na Ecodin?mica de Tricart (1977), no qual, classifica as ?reas de risco e o grau de vulnerabilidade destas ?reas conforme os processos morfodin?micos para elabora??o do ?ndice de Vulnerabilidade Ambiental; e para organiza??o do ?ndice de Vulnerabilidade Social adotou-se uma adapta??o do ?ndice Paulista de Vulnerabilidade Social, elaborado pela Funda??o SEADE (Funda??o Sistema Estadual de An?lise de Dados) do Estado de S?o Paulo, valendo-se de dados que denotam desvantagem social no n?vel do setor censit?rio. Em seguida, com a sobreposi??o destes dois ?ndices, elaborou-se o ?ndice de Vulnerabilidade Socioambiental. Assim, concluiu-se que al?m de espacializar as ?reas de risco indica qual o grau de vulnerabilidade dos indiv?duos potencialmente expostos ao perigo natural. / Contemporary society lives surrounded by various types of risks, causing individuals to be taken by a constant feeling of fear and insecurity, as the negative risks, always bring some harm to the population directly or indirectly involved. The city of Natal has several risk areas, especially on the outskirts of the city, due to the occupation of spaces that have laws and / or natural physical limitations as well as the lack of urban organization, thus increasing the vulnerability of the population living in these areas. The principal objective of this research was to map the areas of social vulnerability and natural hazards in Natal, taking into account the interrelationships between social vulnerability and differential exposure to natural hazards. Therefore, it was necessary to establish, according to the methodology used, the degree of social vulnerability and vulnerability to natural hazard in which individuals are subject, to establish the relationship between society/ risks. In this case, the methodology proposed by Crepani (2001) which is based on ecodynamic Tricart (1977), which classifies the areas of risk and the degree of vulnerability of these areas according to the morphodynamic processes for preparation of the Vulnerability Index was used Physical natural, and for organizing the social Vulnerability Index adopted an adaptation of the Paulista social Vulnerability Index, prepared by SEADE (Funda??o Sistema Estadual de An?lise de Dados) of the State of S?o Paulo, drawing on data that denote social disadvantage at the census tract level. Then, with the superposition of these two indices, it was elaborated a Socioenvironmental Vulnerability Index. Thus, it is concluded that besides spatialize areas of risk which indicates the degree of vulnerability of individuals potentially exposed to natural hazard.
