This paper presents the spatial implication of climate change-related variables and the role of the representation and analysis of the data as a tool for the development of planning policies in urbanized deltas. The presentation illustrates some partial and preliminary results of a broader investigation regarding socio-economic variables too, in order to analyze the spatial impact of changes in deltaic systems. In the deltas’ territories, a complex relation between urban patterns and the natural environment takes place. In order to reach successful adaptation policies regarding climate change and urban growth, it is necessary to implement new methodologies to take into account the spatial impacts of each driver and prepare for possible future scenarios. The study is based on the territory of the Lower Parana Delta and the coast of Buenos Aires province, which are complex lands that are very vulnerable to extreme climate events. Specifically, the case study is the coastal Municipality of Tigre, which is being rapidly transformed by natural and urban drivers and suffers the pressures of the demographic growth of Buenos Aires’s Metropolitan Area and the deep consequences of climate events.
