Item As trajetorias socioespacias dos camponeses do assentamento rio claro em Jatai-GO(Universidade Federal de Goiás, 2011-05-10) GUIMARÃES, Juliana Carneiro; RIBEIRO, Dinalva Donizete; http://lattes.cnpq.br/3182325621648634This work now presented emerged from the professional and personal anxieties, from the actuation in a project developed by the Núcleo de Estudos, Pesquisa e Extensão em Agricultura Familiar NEAF/UFG, in the Rio Claro (P.A.) Projeto de Assentamento in Jataí, State of Goiás. And has as the objective, to analyze the social and spatial trajectory of the families from this setting, besides to verify the influence of these trajectories in the present time of their lives, as seat people. So some specific objectives were established, just as to analyze the social and spatial trajectory of the families from the Rio Claro P.A. in the previous phases to the constitution of this setting: the previous phase to the land battle; to understand how the constitution of the P.A. was realized, and to verify which were the influences of the social and spatial trajectories of the families in the social and productive organization of the setting. These trajectories were divided in three phases, the previous phase to the entering into the land battle, which gives the basis for the first part of the work; the phase of the battle for land, which gives basis the second part; and finally the present phase of their social and spatial trajectories, as seat people, constituting the third part. According to these objectives, we took bold of the following methodological instruments which permitted the development of this study: bibliographic and documental research through the data supplied by the Sindicato dos Trabalhadores Rurais de Jataí (Jataí Rural Labor Union) and the DATALUTA data bank, which permitted the secondary data collection; field research, with the use , as instruments of data collection, of a form with closed and open questions and a semi organized interview, which propitiated the collection of the primary data. In the form we obtained the participation of 17 families who compose the Rio Claro setting, in a total of 19 people. 10 families participated in the interview, totalizing 13 researched people. After realizing this study it was possible to conclude that, to research the social and spatial trajectories from the components of the P.A. Rio Claro was fundamental to understand the social and productive relationships established in the setting and among people of the researched group, being possible to indentify the origins of the families, the cause they were expropriated from the land, and how they entered into the movement of the land battle and how they created the setting which nowadays guarantees them the production of their ways of life, through the work in the conquered peace of land .Item Modernização da agricultura e (re)ordenamento territorial nos Gerais de Balsas/MA(Universidade Federal de Goiás, 2009-01-10) ROCHA, Rosimary Gomes; CALAÇA, Manoel; http://lattes.cnpq.br/1893714192029341The General of Balsas located in the south of the Maranhão had its occupation at a first moment characterized for the available land search for creation of cattle to the untied one for originary creators of other states northeast, mainly of the Zone of Mata, region destined mainly to the culture of sugar cane-of-sugar in century XIX. From the end of the decade of 1970 this space starts to a large extent to suffer significant transformations due to the governmentalactions from occupation of the agricultural border. The arrival of a migratory, mainly sulista flow. They bring I obtain a new form to work the land, established in the use of advanced techniques, culminating in the process of modernization of agriculture in the General of Balsas, being the plantation of the soy the car head of this process. Such transformations in the agrarian space of this region to leave of the decade of 70 of the last century provoke questionings on the appropriation, construction and the use of the territory. The new conceptions on this dynamics in take them to reflect on the relations of being able that they had been installed in the locality, where the territorial processes tied with the monopolista capital if characterize as preponderant. The installation of the agroindústria led to a fast territorial reorganization. One becomes important to still establish, that the new territorialities gifts in the region if also characterize for the distinct model to think and to use the space, since the migrantes load differently obtain the identitários processes of its region of origin of the local population, the called maranhenses farmers. In this context the General of Balsas-Ma evidences it a set of new actions and new objects social technician, actors, economic politicians and, who make use of these objects and create conditions for its reproduction.Item Análise de métodos de realce espectral e temporal aplicados à discriminação de classes de uso e cobertura da terra em áreas de Cerrado(Universidade Federal de Goiás, 2010-03-11) SILVA, Iza Carla de Oliveira e; FERREIRA JÚNIOR, Laerte Guimarães; http://lattes.cnpq.br/8647270006257055The Cerrado biome has the national and international eminence, because it dimensions, around 205 millions ha. in the Brazil, beyond to emphasize like an areas of the global importance, call hotspots. With 9,2% of it is area in the parks and ecological reservation, studs of the mapping of the vegetation indicate a scenery of the conversion estimated between 40 % and 55 %, for areas of the pasture and agricultural. This work has the objective to evaluated the potential of discrimination of the natural and human target from the images with high resolution and high spectral resolution, accentuated amount the spectral dominion like temporal, to identify the better technique and protocols, which results in mapping semi-automatic of the landscape cover in the Cerrado biome, more accurate. It was selected an area test for this analyze, the municipality of Mineiros, the definition of the are was base in the environment importance, because inside of this municipality there is the fountainhead of the Araguaia - Tocantins River basin, the Prata basin and the Paraguai basin, beyond the strategic areas for conservation (Parque Nacional das Emas) and the biodiversity corridors (Cerrado Pantanal). The models of spectral enhancement NDVI, MLME and CP were apply in a LANDASAT TM (orbit/point: 224/73) from march 30 of 2008 (rain season) and august 21 of 2008 (dry season). The statistic analyses show the existence of one spectral confusion more intensify between Campo Sujo and Pasture and Cerrado Sensu Stricto, in all categories of the analyze data. Other results showing that the capacity of discriminate is bigger in the august, the dry season, when there is more distinction in the vegetation. And finally, between the spectral model, which presents better potential to distinction the class was observed by the images, component main, with 96 % of the sample classify correctly. Before the MLME presents results of 91 % in relation to NDVI, with 84 % of the capacity to define the class, this difference is because the number of the patchy in NDVI is less ( i.e NDVI use just two bands, red and infra-red) when compare to MLME and CP. Thus the work consider that application of the spectral enhancement in the image of the original digital values contribution in the distinction potential of the natural and anthropic, concluding that the analyze of the main components increase with the precision of the semi-automatic mapping of use land cover.
