Abstract

Among the methodological conceptions developed for integrated studies of the environment stands out the Geoecological theory, conceived initially like Ecology of the Landscape which bases in the studies of the association of the living beings (biocenose) with its natural space (landscape). Besides that, with regard to the planning of the landscape and the protection of nature, the geoecological vision incorporates the analysis of the socioeconomic and sociocultural components that modify the landscape (anthropic factor). In this way, the investigation tackles the problematic of the not sustainable use of the coastal landscape emphasizing the need to identify the natural space that characterizes the coastal marine band through the study of the marine hydrobiological resources and of the seaboards ecosystems. Like this, with base in the interests manifested by the inhabitants of the traditional communities of La Concepción, La Laguna, Purio and Mariabé; the area of study located in the low watershed of the river Purio (south of Panama), in which it locates the unit of environmental management (the coastal marine band). The thesis aimed to apply the geoecological evaluation of the landscape, based in the methodological proposal of Rodriguez (2012), it evaluates the degree of environmental sustainable of the coastal marine landscape, and justify the proposal of environmental zoning. Besides that, the investigation backed Trollʼs (1963; 1973) geoecological theory, in the methodological principles of the geoecological classification of the landscape at local level; according to Rodriguez, Silva and Cavalcanti (2004; 2007; 2010) and it follows the recommendations of Cavalcanti and Viadana (2007) on the analysis of the landscape for the organization of the geographic space. Consequently, based in the functional zoning of the landscape and by means of the work of field (jointly with the community leaders) was possible to investigate the main degrading geoecological processes, and delimiting the geoecological units in the seaboard band considering the ecological and anthropic elements of the landscape origin. Besides that, the determination of the geomorphological units generated from the data SRTM showed to be fundamental for the realization of the mapping of geoecological units in the coast. Finally, the results show that the geoecological evaluation of the landscape makes possible the creation of regulations and laws for the development of the economic activities as well as those for the environmental protection, decisions that, contribute to improve the quality of life of the local communities.
