Description
Summary:The Lower Camaquã River Watershed is settled within two major geologic systems: the Pre-Cambrian basement and the Southern Brazilian Coastal Plain. Geological, environmental and socio-economic characteristics of this section of the watershed provide a heterogeneous landscape mosaic of interconnected natural and anthropic elements. In this work, the Sapato Creek watershed is used as a case study for an environmental analysis of the Lower Camaquã system. Landscape elements were identified, described and modelled as a way to understand their structure and dynamics. Satellite images (1:100,000) and field checking were utilised in the characterisation of the landscape elements and identification of land use categories. The results supported the characterisation of the structural and functional organisation of the watershed, potential impacts and the suitability of land use for the system. A conceptual methodological strategy is presented as an effective tool for transferring the recommendations produced in this work to decision-makers directly involved with environmental management in the region. The strategy relies on the interaction between scientists, decision-makers and watershed stakeholders to foster the identification of possible educational actions that could lead to a rational use of land and natural resources in the watershed.
