The Amazon undesignated public forests total more than 60 million hectares and have been showing increasing values of deforestation rates. The Mamuru-Arapiuns Glebas Complex - CGMA, located in western Pará, had its territorial planning driven by the promotion of a forest-based economy, via state forest concessions. This study analyzes territorial planning and forest governance in this region in the period 2006- 2018, focusing on the process of destination of public forests and on the participatory process of social concertation built by multi-players and their different planning proposals, how this process contributed to changes in land use and deforestation rates, in addition to the performance of forest governance in the different post- territorial planning land management arrangements. Our hypothesis was that the territorial planning of undesignated public forests contributed to the resolution of historical conflicts, as well as allowing, in general, better forest governance, encouraging forest uses compatible with the land designation and reducing deforestation. The territorial and cartographic disputes were analyzed through the overlapping of different planning proposals and documents from public agencies. The analysis of the dynamics of land use was carried out in a GIS environment using data from the MapBiomas Project. For the assessment of forest governance in the different post-territorial planning land arrangements, performance indicators were elaborated, and their compliance evaluated based on documental analyses. It was observed that although the territorial planning has not reduced deforestation rates, it has contributed to the resolution of most of the existing conflicts, in addition to stimulating land uses more compatible with the land category and greater performance of management agencies through licensing and monitoring of environmental activities. The newly designated areas, although based on solid legal framework, showed lesser compliance with management mechanisms. The overall governance of the CGMA was satisfactory, although it differed between different land arrangements. With the allocation of public forests, it is plausible to expect some forest loss in favor of better local governance. In this sense, the consolidation of the land allocations established in the territorial planning is still crucial for the effective contribution of a forestry policy for local development, anchored in the promotion of sustainable productive practices and in the curbing of illegal practices that threaten the governance of public forests in the Amazon.

Quantificação e avaliação de abertura no dossel em áreas de concessões florestais: Mamuru-Arapiuns-PA

The Amazonian tropical rainforests have historically been the target of non-sustainable land use practices, remain the scars of degradation from predatory logging, indiscriminate use of fire, high rates of deforestation and other activities that interfere in forest biodiversity conservation actions. In this scenario, the State actuation through policies that encourage more sustainable uses is needed, like the forest concession that seeks to contribute to natural resources conservation and maintenance of biodiversity through forest management. The generation of products like Normalized Difference Vegetation Index, Linear Spectral Mixture Model and Canopy Gap Fraction was done in order to create elements of interpretation and analysis of the canopy openness variable. This research studied the Forest Management Unit I of the Mamuru-Arapiuns lot, west region of Pará state, where canopy openness of this forest concession area was quantified and evaluated through multispectral images and hemispherical photographs to analyze the degradation and quality of the management executed in this area. The results obtained showed that is possible to establish a monitoring process by the use of the sensors and technics applied, once the LSMM data, specially the unmixed image soil showed strong covariance relation with the field data from hemispherical photographs, allowing it to be considered a good warning tool to amazon forests monitoring actions. This way, it is possible to make the management of forests more accessible to the government and non-governmental or private organizations to police the logging actions and aggregate the population that live on these areas, with income opportunities and forest conservation.
