Introduction: This thesis presents a contribution to the understanding of the social production of American Cutaneous Leishmaniasis (ACL). Particularly, the thesis deals with questions concerning the trajectory of vector diseases, such as leishmaniasis, that may be being transformed by the suppression of forested areas by the expansion of sugarcane monoculture, in this case highlighting the ACL problem, which has as vector the sandflies. Objective: The general objective was to establish relationships between diversity, spatial distribution of sandflies, production of Geographic Space and population health, characterizing the Pathogenic Complex of American Cutaneous Leishmaniasis. Methodology: Thus, we use the geographical knowledge of Biogeography, literature review, both systematic and narrative, field surveys and laboratory work and statistical analysis. Results: A total of 30 field surveys were carried out and 2171 specimens of sandflies were distributed among the fragments of the Mico-Leão-Preto Ecological Station, Água Sumida, 72 specimens with seven different species and Ponte Branca, 52 specimens with 11 different species and in the lower strait of Morro do Diabo State Park, 2044 specimens with 13 different species. In all cases it presents greater diversity in preserved areas and less diversity in colonized areas. Different geographic environments were coexisting with the area in question, being forest areas (natural environment), passing through rural areas with agrarian reform settlements and extensive cattle ranches (technical environment), as well as sugar cane agriculture farms (scientific-informational). Discussion: It is evident that the sugarcane cultivation activity modified the epidemiological profile of ACL in the region of Pontal do Paranapanema, understood from a Pathogenic Complex. This is because the implantation of the sugar cane activity gives new directions to the model of cultivation in the field and this interferes in the ecological dynamics of this disease affecting the local population. Thus, this study resulted in a new characterization of the study area, spatialization of the vectors in the region, in the establishment of the ACL Pathogenic Complex and in the delimitation of a research field called "Biogeography of Health". Conclusion: These results contribute to the evolution of geographic knowledge, the training of geography students and also to the strengthening of health surveillance. (AU) | |
