The Municipalities Quality Green Index IQM-Verde (in Portuguese) was developed after five years of work. The study sighted to portray the characteristics of rainforest fragmentation. As an element to support the environmental management planning, the project identified priority corridors to link forest fragments. The major contribution of the work, under the conceptual point of view, was to reorient the debate about forest fragmentation in the State of Rio de Janeiro. The IQM - Green project presented, exhaustively, places where there were losses and gains in stocks with arboreal vegetation, calculated by municipalities, watersheds and protected areas. There are important issues that have been raised and are still waiting for better answers. One of them is trying to explain, based on landscape ecology, what are the mechanisms that facilitate or hinder the natural process of forest succession. The situation of forest succession is completely different from one region to another. In the Northwest of the State of Rio de Janeiro there are clear indications of shrinkage and fragmentation of remaining; on the other hand, the mountainous region of South State shows clear signs of recovery and reforestation. New concepts of environmental management intend to minimize the effects of fragmentation and spatial isolation of species. The increase of connectivity through corridors between protected areas and even among the most well preserved fragments is indicated by many researchers as one of the most effective ways to promote the maintenance of the remaining forest - in the long run - and even promote the functional recovery of some ecological units currently isolated. The current generation of researchers and public administrators is faced with the problem of control of the processes that lead to forest fragmentation. Therefore, there is an urgent need to understand all the consequences associated with forest fragmentation and, at the same time, discover the inhibitory effects of this complex phenomenon that has natural and social causes. The central objective of this thesis is, from the History of Mentalities elements and Decision Theory, building scenarios anthropogenic pressure on forest remnants and propose a possible program of economic intervention, legal and policy, called BolsaFloresta , able to relieve the current process of forest fragmentation.
