Building a Dynamic Potential Map for Arapiraca city

Abstract

The reduction of climate change in the urban environment should be studied using instruments linked to urban planning, such as the Urban Climatic Analysis Map. The objective of this work was to elaborate the Dynamic Potential Map of the Arapiraca-AL, considering the ground coverage and thermal mitigation factors such as water masses and topographic slope to subsidize the construction of the local Urban Climatic Analysis Map. A multicriteria analysis method was adopted for spatial analysis using the QGis software. The methodologies adopted were: a) elaboration of a soil occupation-porosity map of the urban site; b) elaboration of a map of the proximity of water elements; c) elaboration of a map of slopes/topography and d) microclimate monitoring to verify trends and differences in the climatic performance of urban fractions. As a result, the dynamic potential map showed that Arapiraca has an urban structure with low thermal mitigation capacity in the Centro neighborhood and surrounding neighborhoods due to the high rate of occupation of urban land and few body of water. However, in the peripheral neighborhoods there is a predominance of areas with high potential for using ventilation, highlighting the need to apply bioclimatic strategies in the urban planning and design process, through the review of local urban legislation for environmental adequacy in the process of local territorial occupation.
