| Sumario: | The Lower Delta of Paraná, located at the Tigre Party in Argentina, is part of a large wetland system. It is an area of great ecological and environmental interest, as it highlights the supply of ecological goods and services from which local and regional communities benefit rural and in a large dimension urban structures.\nThroughout the increasing population and development of the area, activities have emerged that have excelled under socio-economic or political conditions, as well as due to the natural determinants of the area, the latter being a relevant factor in the housing and tourism dynamics highlighted today. Thus, distinctive aspects at a natural, landscape and geographical level caught the attention of an elite real estate market, with the presence of the Nautical Development (ND) models in the insular zone at the beginning of the 21st century. ND models maintain characteristics and particularities of the Gated Communities (GC) or countries present in the north of the Buenos Aires Metropolitan Area or BAMA; GC projects have been characterized for generating large territorial transformations in flood prone areas, directly affecting ecological goods and services, thereby amplifying the risk of flooding in surrounding areas. \nSimilarly, the NDs present in the insular area do not sustainably consider the physical and natural determinants of the area, influencing the hydrological dynamics and possible threats of the Lower Delta, among other impacts at the environmental level, thereby implying a situation of vulnerability and a closer approach to risk situations.\nFor the aforementioned reasons, the most relevant NDs in the insular area of Tigre, Colony Park and Isla del Este are considered as case studies in the relationship of this type of projects and the increased risk in areas of great natural interest, such as the Lower Delta of Paraná. The background and the physical and socio-economic determinants of the area are taken into account in the analysis of the case studies. This is because the mentioned determinants are fundamental to understand the risk scenario facing the Lower Delta of the Tigre Party, associated with recurrent flooding, and the spatial reconfiguration to which the areas were subdued.\nA spatial analysis theme is the methodological approach of the present investigation, interpreting Landsat 5 TM images from 1998 and 2011 from geographic information systems (GIS). The goal was to spatially identify and analyze the main physical and anthropic determinants of the case studies; obtaining as a result measurable layers through GIS processes that allowed defining qualitative and quantitative variables involved within the threats and vulnerabilities of the area, in order to establish the level of risk generated by the referred NDs.\nThe premises used to analyze the case studies are: the level of impact on the territory and the relationship at the level of vulnerability and risk. Based on the analysis, it is concluded that both development projects represent a relevant sample of the capacity of damage in natural areas such as the Lower Delta. Because the Lower Delta represents a socio natural vulnerable area, continued development will only increase the risk of vulnerability. The impacts are irreversible, setting up a socio natural vulnerability with an increased risk of incidence over zones similar to the Lower Delta. |
