Several studies about the ﬁ shing sector have been carried on in the Amazon, however, the majority of these studies are concentrated on regions near the Amazon river bank and its delta. This work has the objective to characterize the Purus commercial ﬁshing ﬂeet and the ﬁsher in three counties: Manoel Urbano and Sena Madureira in the Brazilian state of Acre (AC) and Boca do Acre, in Amazonas (AM).We estimate the ﬁsheries production and income. The results show that in Manoel Urbano (AC) lake ﬁsheries predominate while in Sena Madureira (AC), the diversity in ﬁshing places are lager with ﬁshers using lakes, river and creeks. In Boca do Acre (AM), the largest among the three cities, the most important ﬁshing plots are Pauini and Labrea areas. In relation to boats, Manoel Urbano ﬁshers use only canoes with most of it motorized. In Boca do Acre, ﬁ sheries are practiced mainly in boat. In relation to ﬁshing trip costs the results showed that variable costs are the main costs for canoes (63% of total income) and boats (73% of total income). The analyses showed also that motorized canoes have larger productive capacity per unit of effort (CPUE) in relation to boats.

Desterritorialização produtiva e mudanças no Marajó: arrecadação, desemprego e violência na cidade de Breves (Pará-Brasil)
(Universidade Federal de Viçosa, 2020) ALVES, Odair José Aragão; SILVA, Christian Nunes da; REIS, João Francisco Garcia; CAETANO, Vivianne Nunes da Silva
After the closure of the large timber companies in the Municipality of Breves, it has become evident the changes in both economic cycle and population distribution, in addition to the greater spatial concentration of the population in the urban space, thus accentuating the increase in the distinction between rural and urban areas, given that both economic and social problems have greatly influenced the development of the Breves / Marajó / Pará region. This text brings the characterization of Breves municipality, presenting an overview of the city, through its economic and social aspects, as well as seeks to analyze the socio-territorial changes that occurred in this municipality in recent years. In order to held the debate proposed here, it was necessary to carry out bibliographic research and fieldworks, in addition to research in public agencies, which provide population and crime data of the city. The Municipality of Breves has been undergoing significant modifications, mainly due to the decline of logging activity and the emergence of "new objects" (numerous commercial and service establishments, penitentiary, etc.) that have been changing urban dynamics and reflecting directly on the way of life of the population.

Geotecnologias aplicadas ao ordenamento territorial pesqueiro industrial do estuário amazônico
(Universidade Federal do Pará, 2012-06-12) SILVA, Christian Nunes da; ALMEIDA, Oriana Trindade de; http://lattes.cnpq.br/0325909843645279; MCGRATH, David Gibbs; http://lattes.cnpq.br/4373475491613670
The present work aims to reflect on the fishing activity geographically, with some categories of territorial analysis that can be worked in fishing, taking into consideration the livelihoods of fishermen, the territorial scope of its influence on fisheries and the mechanisms of spatial representation in environment computer that are currently available, capable of achieving the spatial patterns of coverage. This analysis was based on the consideration that the fishery is of utmost importance for the supply of urban centers, the main source of livelihood and income of populations of fishers in the Amazon region. New methodological procedures and technological processes have generated a significant fishing increasing both the apparent exhaustion of resources, and the recognition and functional protein, fish products that have gained in recent years, as a means of proper nutrition for the maintenance of quality of the consumer. Thus, the main objective of this study is to verify and discuss the feasibility of using geotechnology in the current planning model that can be seen fishing in the Amazon region, seeking to understand how this land use in fishing may include: geo; information about equipment fishing used to catch fish, knowledge of fishermen and the Brazilian legislation. Literature searches and field (in the Caeté bay and river Ituquara, Pará state), integrated to work in the laboratory, using geoprocessing techniques of remote sensing products allow mapping the dynamic moment of some socio-spatial relationships and structural by passing fishing, so it is important to focus on mechanisms of assistance to the planning of fishery resources. The technology called “geoinformation” science, has shown greater visibility in environmental studies and therefore should be included in the fishing industry as an important mechanism for monitoring, surveillance and research for the future management strategies.

Perda de cobertura florestal e políticas públicas em assentamentos de reforma agrária na Amazônia: análise do P.A Tuerê, Novo Repartimento, Estado do Pará
(Universidade Federal de Roraima, 2023) FARIAS, Monique Helen Cravo Soares; CARVALHO, André Cutrim; SANTOS, Cleber Assis dos; SILVA, Christian Nunes da
From the point of view of history, the Pará Amazon, the territorial correspondent of the State of Pará, has been undergoing a series of major transformations, especially in its frontiers. In the past, this region was a priority target for colonization programs and for the establishment of rural settlements, whose main objective was to populate remote areas of the country as a kind of geopolitical strategy. At present, however, the intensive land use dynamics on the Frontier of Pará indicates a significant increase in deforestation in areas of rural settlements. In these circumstances, inserted in the region of the Arc of Deforestation, there is the municipality of Novo Repartimento, state of Pará, which has 32 rural settlement projects in a total area of 5,596.5 km2. Among them, there is the Tuerê Federal Settlement Project, created on August 4, 1987, the first project installed in Novo Repartimento. In this context, the objective of this work is to analyze, characterize and map the contribution of Tuerê Settlement Project to deforestation in Novo Repartimento, Pará, during the period from 1985 to 2020. The land cover classification derived from MAPBIOMAS was used to identify the deforested areas in Tuerê. The results are important to show the influence that the Agrarian Reform settlement projects have on the total deforestation of the municipality, evidenced from an increase of 1,448.73 km2 in deforested areas in 35 years in the Tuerê Settlement Project.
