The Santa Ana de Vuelta Larga’s parish, located in the Portoviejo’s basin river of the province of Manabi, Ecuador, is one of the most affected areas by inundations. For this reason, in this recent study it was analyzed its global vulnerability, through physical, social, economic and ecological elements. For this was used direct observation of aspect as the location, conservation and building materials for the construction of housing, also personal and descriptive polls to provide information about risk management and economic lost, and the Geographic Information Systems for the cartographic analysis of environmental aspects of the parish. Quizzes were realized randomly for social groups of 378 people, this is the result of finite population, with a margin error of 5% and a confidence level of 95%. The results show that global vulnerability is average (55%) where the social aspect is more influent, since there is a lack of preparation upon the risk of local governmental institutions and population. Followed by the physical aspect, because of the geographic proximity of households to the river, the ecological factor, for the vegetative cover reduction and the sealed soil, and in a minor proportion of the economic factor because of the location of the commercial zone in places with inferior slopes of 2.5°. Finally, the parish vulnerability is linked to its geographical location, lack of land development planes, preparation for risk and change of soil use and vegetation cover.
