Regarding the historical process of land use and cover in Brazil, there is the degradation of native vegetation in the called permanent protection areas (APPs), on the banks of rivers. In Southeastern Pará, with the expansion of livestock activity over time, these areas were impacted, generating biodiversity loss and pressure on water bodies. This paper the land use and cover dynamics was analyzed in two areas in the municipality of São Domingos do Araguaia -PA to simulate the priority areas for arboreal component inclusion, aiming for the restoration of APPs in a farm and a rural settlement, if strategies of arboreal component inclusion are adopted. In both case studies, there are degraded pastures in extensive areas, driven by the expansion and intensification of traditional livestock in the region from 2004 to 2014.

The agrarian changes occurred in the Amazon region after the settlements and programs creation to support family farmers deserve to be addressed, especially the implications they have in the expansion of pastures and increased deforestation on the one hand, and the expectation that these changes may influence farmers to stay in the same area keeping their production systems. This work presents research results of two settlements of Agrarian Reform located in the town of Maraba-Para at different historical contexts. Relationships between rural credits, implantation of pasture and cattle activity were analyzes. It also evaluates the current situation and prospects of farmers who develop this activity remain on their lots. Uses observation in loco, surveys and interweaver and statistical comparisons to compare groups of establishments with and without credit, with or without the sale of milk, and to assess the differences between indicators of deployment pasture and livestock activities to identify which variables best justify the progress of implementation of pastures as well as of production, productivity and the sale of milk. The increase of pastures implantation is more closely linked to size farm and the time elapsed from first implantation of pasture and less of the credit, but milk production is higher when credit is present. The expansion of livestock by establishment of agrarian reform is hampered by the extensive form of development of this activity, which weakens the perspective of farmers remain on their lots with implications with advancement upon new forested areas and the rural exodus.

Dynamics of forest deforestation in the amazon of pará: an approach centered in space econometry
(International Journal of Development Research, 2018-06) CARVALHO, André Cutrim; SILVA, Raimundo Nelson Souza da; FILGUEIRAS, Gisalda Carvalho; CARVALHO, Abner Vilhena de; FREITAS, Tatiana Pará Monteiro de; BENTES, Elisabeth dos Santos
This article aims to theoretically discuss the main factors responsible for the dynamics of forest clearing in the Amazon of ofPará, an approach perspective performed through spatial econometrics. The basic hypothesis is that the expansion of the agricultural frontier is the conductive element from forest deforestation phenomenon in Pará. In this context, the spatial econometrics served as an extremely important tool to measure, from the results obtained in spatial econometric model the effects that the forest clearing has led in Pará. The main conclusion is that the increased expansion of cattle ranching in the Amazon frontier driven by demand from abroad has directly influenced the increase of deforestation, hindering the development of sustainable activity in the region.The period chosen for the spatial econometric analysis covers the years 2000 and 2008 due to high forest deforestation rate in the state of Pará.

Ocupação dos espaços, gestão e degradação das pastagens entre pecuaristas da microrregião de São Félix do Xingu-PA
(Universidade Federal do Pará, 2011-08-02) CLAUDINO, Livio Sergio Dias; POCCARD CHAPUIS, René Jean Marie; http://lattes.cnpq.br/2908492529201445; https://orcid.org/0000-0003-2200-0637; DARNET, Laura Angélica Ferreira; http://lattes.cnpq.br/3450720474559096; https://orcid.org/0000-0003-2523-9248
In many places in the Brazilian Amazon the livestock is a very common activity. In the central eastern part, in the municipalities of São Félix do Xingu and Tucumã, this activity showed an exponential growth, especially from 90 years, where was observed one rapid expansion of pastures and cattle herds. Questions about the role of this activity emerged due to deforestation increase are consequence of the conversion of forests into pastures of low quality. Strong relationship among deforestation, pasture degradation and farmer migration were pointed in the last two decades by scientific works. So pasture degradation can be a key phenomenon in the farmers‘ decision to migrate to new areas. This study aims to analyze in micro region São Félix do Xingu, under the research Network – Geoma, if the pasture degradation causes a new deforestation and as the degradation is influenced by pasture management, herd management. The hypotheses were: i) forms of occupation and management to space are influenced by socioeconomic, environmental and political factors, by the land ownership and by the pastures productivity ; ii) the pastures and herds management practices are the main cause of pastures degradation; and, iii) the new deforestation are influenced by pastures degradation. Interviews done were with 63 farmers from September to December 2008. We use statistical regression models to identify variables that influence the stages of pastures degradation and the variance analysis (ANOVA) for compare the variables independents between the different groups of farmers. The results showed that among all socioeconomic categories of farmers, the forms of space occupation and management and status of pastures are very similar. Distinct socioeconomic categories of farmers are influenced by different factors of pastures degradation. Farmers in socioeconomic disadvantaged situations were mainly affected by external factors such as dry season, attacks by pests. However, unlike the hypothesis proposed, the degradation of pasture does not cause farmer migration and opening new areas. The intensification on pasture management is the strategy adopted by all categories of farmers; especially by the reform of pastures and increase in the number of divisions for reduce the pressure on pastures, the seasonal variation effect on the herds during the year and to make improvements in pastures.

Sequestro de carbono em sistemas silvipastoris de regeneração natural da agricultura familiar, São Domingos do Araguaia - PA
(Brazilian Journals Publicações de Periódicos e Editora Ltda, 2021-09) GUIMARÃES, Tatiane Pereira; MANESCHY, Rosana Quaresma; OLIVEIRA, Ilmaione Keisa de Souza; CASTRO, Albinei Araujo de; OLIVEIRA, Pâmela Dias de; COSTA, Karolinny Carneiro Guerra
This research aimed to quantify the carbon stock of aboveground living vegetation in silvopastoral systems of natural regeneration practiced by family farmers in the settlement project Belo Horizonte II. The settlement is located in São Domingos do Araguaia – PA and the SSP managed from the natural regeneration of tree species constitutes an alternative for the integration of socioeconomic and environmental objectives, seeking sustainability for family farming in Southeast Pará. The biomass of the arboreal component was obtained from data from the field evaluation carried out in December 2009. The arboreal biomass per hectare was estimated from of calculation: BA = (ΣBA/1000) x (10000/plot area) and the carbon stock was estimated from ΔCBA = (BA x CF), where: ΔCBA = amount of carbon in aboveground living biomass (t C/ha); BA = aboveground living woody biomass (t DM/ha); CF = is the carbon fraction (t C /t MS) which, according to the IPCC (Intergovernmental Panel on Climate Change), defaults to 0.5. The carbon stock in the aboveground living biomass was 14.08 t C/ha, being 0.27 C t/ha and 13.81 t C/ha for the woody and non-tree vegetation biomass, respectively.
