O ecossistema urbano da ocupação Santa Luzia: Análise dos impactos por técnicas de geoprocessamento e proposição de Soluções baseadas na Natureza

The informal occupation Santa Luzia, near the Parque Nacional de Brasilia, is inserted in the watershed of the headwaters of the Corrego Cabeceira do Acampamento, which defines its Urban Ecosystem. The Government of the Federal District seeks to reallocate the occupying population of the region with a proposal for a 3.2 km long linear social housing project as a mitigation measure, pressured by the Ministerio Publico do DF e Territorios, which accuses the increase of environmental impacts in the region. In order that defend the maintenance of the population in the place, a simplified ecological inventory was carried out with spatial data about socio-economic-environmental aspects of the watershed and improvements were indicated according to the Nature Based Solutions. The mapping included NDVI; Soil Type; Relief; Declivity; Risk of soil loss through erosion, Risk of contamination; Vegetation types; and Degree of soil waterproofing analysis. The result of the inventory showed that the environmental impact generated by the occupation is less than the adjacent areas, being a positive scenario to include the population in the regeneration process with minor adjustments and changes, mainly sensitive to water based on the vision of ecosystem services for the treatment of effluents at the landscape level of treatment; resource source, vegetation adequacy.
