Item Análise dos impactos da competição pelo uso do solo no estado de Goiás durante o período 2000 a 2009 provenientes da expansão do complexo sucroalcooleiro(2011-12) Abdala, Klaus de Oliveira; Ribeiro, Francis LeeThis article aims to analyze the sugarcane specialization in Goiás State, at the municipal level, as a result of competition for land use and the impacts of this process on: substitution of crops, in the use of forest remnants and in the consumptive use of water by sugarcane. The results suggest that the expansion of sugar cane promotes local specialization, where, preferentially, replaces temporary crops and induces the displacement of the other crops, endangering the forest fragments. In addition, part of the expansion is located in areas of moderate to high risk of drought for sugar cane cultivation.Item Os assentamentos rurais frente à expansão da monocultura da cana-de-açúcar no estado de Goiás(2014) Gosch, Marcelo Scolari; Ferreira, Manuel Eduardo; Abdala, Klaus de Oliveira; Silveira, Marina Aparecida daBrazil is currently the world’s largest producer of sugarcane, and the state of Goiás is the third in terms of planted area in the country, surpassed only by São Paulo and Minas Gerais states. During the new expansion process of the sugarcane in Goiás, it has occupied the most diverse territories, even if agribusiness or family farming. This article aims to discuss some aspects related to the insertion of the sugarcane monoculture in areas with a predominance of family farms, especially into the Rural Settlements projects provided by INCRA in the state of Goiás. Among the materials and methods, it was analyzed the expansion of the sugarcane cultivation in Goiás, between the years 2005 and 2011, in areas of rural settlements of agrarian reform - INCRA/GO-SR04 circumscription. They were analyzed in a GIS environment, with data provided by INCRA/GO, LAPIG/UFG and INPE/CANASAT, verifying the presence of sugarcane crop in these settlements. The results show the majority of rural settlements not in areas of infl uence of the sugarcane. However, some occurrence was registered in the nearby settlements areas, where there is an infl uence up to three ethanol plants. Although we have not found the trend of sugarcane cultivation in these settlements, the study suggests periodic monitoring in such locations, using data obtained by remote sensing.Item Caracterização preliminar da agricultura irrigada em Cristalina-GO, a estreita relação entre o desenvolvimento sustentável e o crescimento econômico(2016) Furquim, Maria Gláucia Dourado; Abdala, Klaus de OliveiraThe study portrays the challenge of producing food, by the intensification of invested capital used on technologies in the field, in balance with the environmental preservation and the sustainability of the agricultural practice. In this sense, an exploratory and descriptive research was performed to outline the current scenery of irrigation in Cristalina, State of Goiás, in relation to the main institutional legal elements in the regulation and control of water resources that is ANA’s competence, once the management process of water in irrigation is a parameter that beacon the levels of development and competitiveness in this sector. Especially in Cristalina, where the availability of water for irrigation is a generating factor of inter and intrasectoral conflict. It was confirmed that there is an organization of irrigators, with the implementation of actions in relation to the water use efficiency, facing the storage of rain water in dams and the soil profile improvement in a way to get an allocative efficiency in the use of water, and a consequent increase in the agricultural income to the detriment of the use of water resources in order to overcome the obstruction that the misalignment of regulatory organizations exercise in the promotion of a sustainable irrigated agriculture.Item Risco de impactos ambientais gerados pela dinâmica de uso do solo no estado de Goiás: uma abordagem multimétodos(2016-02) Abdala, Klaus de Oliveira; Ribeiro, Francis Lee; Ferreira, Manuel EduardoThis article analyzes the dynamics of land use between the main agricultural activities in the state of Goiás and the risks of impacts of this process on alternative crops, the consumptive use of water in remnant forest areas, and the risks of land degradation and water contamination. From a multimethod approach combining econometric methods, statistical, geographic, geological and agricultural, we identifi ed, as a result of this dynamic, specialized municipalities in each of these activities, in which the soybean and corn replace the pasture farming, moving it to other areas, where it makes the most responsible for deforestation. In addition, part of this specialization was located in risk areas, indicating that these agricultural activities may be the most responsible for edaphic and hydrologic impacts observed on the scale of river basins.
