“…Traditionally, studies relating land use and occupation with LST employ mostly linear models, as seen by Marques et al (2005), Araújo et al (2017, Bezerra et al (2018), andBecker et al (2020). However, the quality of this model shows variation among some literature, obtaining good performance in some studies and others not.…”

Land surface temperature is a physical-environmental variable that is the target of studies in climatology and heat island phenomena resulting from the urbanization model of the 21st century. It is known that each object has a different thermal capacity, which results in higher or lower temperatures. The modeling of temperature as a function of objects on the land surface can allow understanding between these variables. It can corroborate temperature forecasts with the alteration of objects in an area. The objects on the Earth's surface can be computed with geoprocessing techniques that aim to detail Land Use and Occupation. This paper evaluates the Linear, Exponential, and Sinusoidal models to determine which of these models is more expressive for the study of the land surface temperature as a function of land surface objects. For this purpose, images from the Landsat 8 satellite were used to calculate the Earth's surface temperature and determine the scene's objects. To determine the scene's objects, the Soil Adjusted Vegetation Index (SAVI) was used, which is one of the techniques for obtaining Land Use and Occupation. For model analysis, Akaike's Information Criterion (AIC), Bayesian Information Criterion (BIC), and Sum of Square of Residuals (SSR). According to the AIC, BIC, and SSR criteria, the sinusoidal model presented better performance when compared to the other models. However, there are large variations in SSR between classes, especially for the pasture class, which makes the models not highly explanatory.

Land use and soil physical quality are related. In this work, the S index was used to evaluate the physical quality of the soils of three rural settlement units located in the Brazilian Cerrado, with areas ranging from 700 to more than 4000 hectares, based on a novel method. To map the S index, a set of pedotransfer functions for water retention curves was adapted according to a broad range of clay content for Cambisols, in three depth layers. Some rural units presented associations with classes of land use. In general, deeper layers presented higher values of S. In areas with less than 370 g/kg of clay, land uses that provide low soil cover should be avoided to prevent physical degradation.

Estudos sobre a influência de assentamentos rurais no processo de desmatamento são normalmente controversos. Alguns apontam uma aceleração desse processo, enquanto outros demonstram que nesses locais a dinâmica de uso do solo segue uma tendência regional. No Cerrado (a savana brasileira) esse é um fenômeno ainda pouco conhecido. Nosso objetivo foi analisar o uso e a cobertura do solo em assentamentos rurais do município de Goiás – região com grande destaque nacional –, com foco nas áreas de preservação permanente (APPs) de cursos d’água. Foram empregadas técnicas de geoprocessamento e classificação de imagens de satélites para quatro anos (1985, 1991, 1995 e 2018), com abrangência temporal de 33 anos. Para verificar o padrão do uso do solo em áreas dentro e fora de APPs, nos assentamentos rurais e no restante do município, foram empregadas análises de componentes principais. Os resultados indicam que as áreas com vegetação nativa reduziram em 33% e 34%, para os assentamentos e o restante do município, respectivamente. As classes ligadas às atividades agropecuárias tiveram aumento entre o ano inicial e final do estudo. A ocupação do solo por atividades agropecuárias, dentro das áreas de preservação permanente, teve uma maior redução nos assentamentos. Concluímos que as dinâmicas do uso e ocupação do solo nos assentamentos e no restante do município seguem uma tendência parecida, porém com um atendimento ao código florestal ligeiramente maior nos assentamentos, representando uma maior conservação relativa de áreas nativas do Cerrado. Dynamics of occupation and environmental liabilities in rural settlements in the municipality of Goiás, Goiás A B S T R A C TStudies are controversial about the influence of the implantation of rural settlements in the deforestation process, some point that there is an acceleration of this process, others already show that in these places the dynamics of land use follows a regional trend. In the Cerrado (the Brazilian savannah) this is still a little-known phenomenon. Our objective was to analyze land use and cover in rural settlements and for the municipality of Goiás, where they are located, with a focus on permanent preservation areas (APPs) of water courses. Geoprocessing and satellite image classification techniques were used for four years (1985, 1991, 1995 and 2018), with a time span of 33 years. To check the pattern of land use in areas inside and outside APPs, in rural settlements and in the rest of the municipality, principal component analyzes were used. The results show that the areas with native vegetation reduced by 33% and 34%, for the settlements and the rest of the municipality, respectively. The classes linked to agricultural activities had an increase between the initial and final year of the study. The occupation of the land by agricultural activities, within the areas of permanent preservation, had a greater reduction in the settlements. We conclude that the dynamics of land use and occupation in the settlements and in the rest of the municipality follow a similar trend, it cannot be said that the settlements are responsible for a greater deforestation of native areas of the Cerrado.Keywords: deforestation, Cerrado, geoprocessing, land use.
