Manejo da arborização urbana: comparações entre cidades do Brasil e da Argentina

Abstract

Urban tree management plays a key role in improving environmental quality, social well-being, and urban landscape sustainability. This study provides a comparative analysis of urban tree management plans from three municipalities in Paraná, Brazil (Cascavel, Rolândia, and Dois Vizinhos), and three cities in Misiones Province, Argentina (Posadas, Oberá, and Eldorado). The objective is to identify convergences and divergences in legal, technical, operational, and participatory approaches adopted in both national contexts. The methodology combines documentary analysis of municipal plans, environmental regulations, and technical manuals with semi-structured interviews conducted with public managers responsible for tree management. Data were organized into comparative tables and examined through qualitative content analysis. Results indicate that Brazilian municipalities present more consolidated institutional structures, supported by georeferenced inventories, historical experience, and guidelines aligned with national standards. In contrast, Argentine cities emphasize phytogeographic criteria and native species selection, although with less methodological structuring. Regarding social participation, Brazil shows institutionalized programs, while Argentina relies on community-based initiatives and environmental education. The study concludes that effective urban tree management requires integrating technical foundations, participatory public policies, and environmental sustainability strategies.
