O regime de propriedade e sua relação com a integridade ecológica dos fragmentos florestais urbanos

Abstract

Urban forest fragments might be considered a special type of green infrastructure caused by landscape fragmentation, that in a planned or a non-planned way generate the presence of remainder of forests and other kinds of native vegetation inside the urban web. Being “built” spaces, these forest fragments are under the influence of individual and collective action and also of the social institutions (property systems, rules, laws and plans) that control the managing of those urban spaces. Based on theories of institutional economy and ecological principles of the landscape and considering the relevance of environmental services valorization, this dissertation has as goal to examine the correlation between ecological integrity of forest fragments and the many different property systems that affect them. The conjecture of this study is the fact that public and private property systems represent different incentive joints to conservation of environmental resources. Having as study field the micro-watershed of Igarapé do Gigante located in Manaus – AM, the spatial and temporal dynamic of each forest fragment was evaluated and analyzed accordingly to its respective property system. Therefore, the main goal of this research was verify if the maintenance of ecological integrity of the urban forest fragments is influenced for the many different kinds of property system that control them. Therefore, it was possible to verify that most of the forest fragments placed in this micro-watershed are under two or more kinds of property systems, coincidentally those were the same fragments that had shown more negative changes over time. So it was possible to realize a clear tendency on forest fragments characterized as multi systems due the great majority had reduced their ecological integrity index.
