This study proposes alternative guidelines and instruments related to governance in overlapping territories, with a special focus on the Katxuyana-Tunayana Indigenous Land and the Faro and Trombetas State Forests. To this end, the territorial area investigated covered Conservation Units and Indigenous Lands in the Legal Amazon, including those under study, declared, delimited, homologated and regularized. Specifically, the Katxuyana-Tunayana Indigenous Land, located in the north of the state of Pará, stood out. The study was conducted using bibliographic research, analysis using Geographic Information Systems and open-ended interviews. The results showed that the overlap of Conservation Units and Indigenous Territories is a common occurrence in the Legal Amazon, covering 12% of Conservation Units and 14% of Indigenous Lands, totaling 120,665 square kilometers, distributed over 65 identified cases. The Yanomami and Katxuyana-Tunayana Indigenous Lands stand out as the most affected, with territorial extensions overlapping the Conservation Units totaling 43,378 and 19,772 square kilometers, respectively. In addition, the research identified a variety of governance instruments applied in the 65 cases of overlap in the Legal Amazon, with an emphasis on Indigenous Environmental and Territorial Management Plans and Management Plans. Among the cases analyzed, only 19 Indigenous Lands have Indigenous Environmental and Territorial Management Plans, while 26 Conservation Units have Management Plans. In addition, other instruments are used to address territorial governance, such as management agreements, mosaics of protected areas, management councils, public consultations, joint management plans, terms of commitment, among others. In the specific context of the Katxuyana-Tunayana Indigenous Land, the survey involved key players in the territory in order to capture their worldview in relation to the overlap. The results revealed that there are currently no serious conflict situations, although this is a concern expressed by 80% of those interviewed. It is important to highlight the duality of understandings about the legal status of the territory as overlapping. This is due to the lack of clarity in the interpretation of the Brazilian Constitution for these cases, as well as the absence of clear institutional guidelines for operators in the territory. However, the precedent set for shared management in the Raposa Serra do Sol Indigenous Land is being adopted in other areas. Finally, in relation to the current situation of the Katxuyana-Tunayana Indigenous Land, the instruments proposed by this dissertation include coexistence agreements, joint management plans and mosaics of protected areas. In addition, special attention is suggested for the inclusion of these agreements during the revision of the Faro and Trombetas Flota Management Plans.

Participatory management of pirarucu (Arapaima gigas) is a strategy for conserving the species and generating income for fishing families. Management systems in Conservation Units have more robust legal support and greater government support for inspection and monitoring. In contrast, management systems in areas designated as Fishing Agreements face challenges related to coordination and inspection, due to the lack of structure and resources from the State. Therefore, the main objective of this study was to analyze the performance of managed pirarucu fishing, comparing fishing effectiveness, productivity and economic efficiency between Conservation Units and Fishing Agreements in the Amazon. The legislation that regulates this activity in the state was also explored, focusing on Pirarucu Management Systems located in Conservation Units (UC) and in areas of Fishing Agreements outside UC, whose implementation occurred between 2010 and 2012. The research was based on documentary sources provided by the State Secretariat for the Environment (SEMA), which cover the period from 2018 to 2023. The results indicated that the performance of the management areas was similar, with most areas presenting a Fishing Effectiveness Index (IEP) between "good" and "excellent" (above 0.6), with no significant differences between the two categories. Productivity ranged from 12.38 to 93.16 kg/fisherman/day, in the State Conservation Units and Fishing Agreements, respectively. The fishing agreement areas showed higher productivity than the conservation units, possibly influenced by factors such as fishing in shorter periods or the combined use of different equipment. Regarding economic performance, the highest cost identified was fuel, a reflection of the high spending of communities on monitoring and surveillance of the management areas. Despite these costs, all management areas showed positive revenues. The net income of fishermen varied between R$700.00 and R$5,000.00, both in state conservation units and in fishing agreements, indicating a limitation in profitability and suggesting that, despite the efforts, individual earnings often do not compensate for the time and work dedicated to the activity. Regarding legislation, it was observed that, although the management regime and protocol are based on traditional knowledge, it still presents gaps, especially in relation to monitoring activities. It was also noted that public policies for economic subsidies have been essential to improving the income of families involved in fishing, although only two areas studied were able to obtain these benefits, due to a lack of knowledge about the necessary procedures and difficulties in gathering the required documentation. In general, it is concluded that, regardless of the management system, whether in State Conservation Units or in Fishing Agreements, the performance of pirarucu fishing under management regimes has been similar, with no significant differences between the two contexts, demonstrating the commitment of management groups to continue the activity, even in the face of the challenges faced.

Social technologies for capturing and storing water are an important strategy for times of great variation in the distribution and quality of water and for the water and food security of vulnerable communities. In some protected areas, communities are vulnerable, especially in relation to access to this resource. The objective of this work was to identify, through the review of scientific literature and technical documents, social technologies aimed at capturing and storing water in the Brazilian Amazon, and to elaborate and propose indicators to evaluate replicable technologies. 45 community experiences of access, collection and/or storage of water for human consumption were located and mapped in seven states of the Brazilian Amazon. Four indicators and 27 replicability indexes were formulated for social technologies in communities in the Amazon, based on the parameters of water availability; participatory methods; diffusion; and sustainability. The proposal for these indicators aims, in addition to understanding how social technologies can gain scale when reapplied at the community level in the Amazon region, since those that are implemented in communities in protected areas as a public policy result in a certain autonomy in access to Water.

This work sought to analyze how the management and sustainable use of natural resources are carried out in the Jamari community, located in the Saracá-Taquera National Forest, in the municipality of Terra Santa, Pará. The use of resources by the community has occurred since its formation, however considering that it is an integral part of a Federal Conservation Unit of the Sustainable Use category and was not contemplated in its population zone, the mapping of these resources provides subsidies for the fulfillment of the objectives of the FLONA category. The methodology consisted of bibliographic data survey and field research using quantitative, qualitative analysis instruments and geoprocessing tools. Finally, this work serves as a base element for the management of natural resources for all interested parties (community, association, managing body, researchers, governmental organizations).

Fungi of the genus Trichoderma have the ability to stimulate plant growth and suppress phytopathogens, and may be a promising alternative to chemical fungicides of plant diseases. This study evaluated the potential of four isolates of Trichoderma spp., from the state of Amazonas, Brazil, in the control of sclerotium rot (Agroathelia rolfsii) and of six isolates in the promotion of tomato growth, under field conditions. The experiments were conducted in the field and in vitro assays, the enzymatic activity of siderophores, indoleacetic acid (IAA), antagonism and volatile compounds were evaluated by these isolates. The isolate Inpa 2957 stood out by reducing the incidence of the disease to 1.75%, reduced the mycelial growth of A. rolfsii by 89% in paired culture trials and significantly increased tomato yield, reaching a yield of 359.29 g/m2, with a 73.5% increase in yield compared to the control. The isolate Inpa 2473 stood out for its IAA production (60.72 μg·mL−1) and for its ability to inhibit the mycelial growth of Agroathelia rolfsii by 91% through the emission of volatile metabolites, compared to the control without treatment, indicating its potential as a plant growth promoter and biological controller. Based on the results of this study, the isolate Inpa 2957 demonstrated coherence between the performance in the laboratory and in field conditions, where it can be used as an effective alternative for the biological control of sclerotium rot and to increase the productivity of tomato plants in the field. Reinforcing the viability of biological control as a sustainable alternative to the chemical management of the disease, contributing to the reduction of environmental impacts and the strengthening of sustainable agriculture in the Amazon region.
