25. INFLUENCE OF LAND USE CHANGE ON SEDIMENT YIELD: A CASE STUDY OF THE SUB-MIDDLE OF THE SÃO Francisco River Basin
ABTSRACT Erosion risk mapping and assessment are important for planning of natural resource management tool. The objective of this study was to simulate different scenarios of land use in the Sub-Middle of the São Francisco River Basin using the Soil and Water Assessment (SWAT) model to analyze the effects of changes in sediment yield, making comparisons wi

26. Predicting Runoff Risks by Digital Soil Mapping
ABSTRACT Digital soil mapping (DSM) permits continuous mapping soil types and properties through raster formats considering variation within soil class, in contrast to the traditional mapping that only considers spatial variation of soils at the boundaries of delineated polygons. The objective of this study was to compare the performance of SoLIM (Soil Land

27. Genesis and Classification of Soils from Subtropical Mountain Regions of Southern Brazil
ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the locati

28. Australian Children's Literature and Postcolonialism: A Review Essay
Abstract: The theme of land and country is resonant in Australian children's literature with Aboriginal subject matter. The textual and visual narratives present counter-discourse strategies to challenge the colonial ideology and dominant valuation of the Australian landscape. This review essay begins by examining the colonial history of seeing Australia as

29. Exercising Dominion: Landscape, Civilisation and Racial Politics in Capricornia
Abstract The Land in Xavier Herbert's 1937 novel Capricornia acts as a "medium" (38), according to Lydia Wevers, mediating all experiences and developments. In particular, the land is a site of contention between Indigenous and settler groups each vying for an existence very different from the other's. The phrase "exercising dominion" (Fitzmaurice 56) was de

30. Genesis of Soils Formed from Mafic Igneous Rock in the Atlantic Forest Environment
ABSTRACT Different parent materials participate in the formation of soils in the hilly landscape of “Mar de Morros” in the Atlantic Forest environment. Those derived from mafic igneous rock (gabbro) frequently show erosion problems because of land use, which is aggravated by the mountainous relief and soil attributes. This study evaluated the main pedoge

31. Spatial prediction of soil properties in two contrasting physiographic regions in Brazil
ABSTRACT This study compared the performance of ordinary kriging (OK) and regression kriging (RK) to predict soil physical-chemical properties in topsoil (0-15 cm). Mean prediction of error and root mean square of prediction error were used to assess the prediction methods. Two watersheds with contrasting soil-landscape features were studied, for which the p

32. Comparing how land use change impacts soil microbial catabolic respiration in Southwestern Amazon
Abstract Land use changes strongly impact soil functions, particularly microbial biomass diversity and activity. We hypothesized that the catabolic respiration response of the microbial biomass would differ depending on land use and that these differences would be consistent at the landscape scale. In the present study, we analyzed the catabolic response pro

33. TIPOLOGÍA Y USOS DEL SUELO EN AGROECOSISTEMAS DEL VALLE DEL GUAMUEZ, PUTUMAYO – COLOMBIA
ABSTRACT The objective of this research was to analyze different agroecosystems located in a region of the Departamento de Putumayo (Colombia) and its sociocultural relationship with productive and land conservation contexts, based on the conceptual and methodological aspects of agroecology. A mixed methods study was carried out, and soil testing methodologi

34. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this

35. Impact of natural climate change and historical land use on landscape development in the Atlantic Forest of Rio de Janeiro, Brazil
Variações climáticas e o histórico do uso da terra tem grande impacto no desenvolvimento da paisagem da Mata Atlântica brasileira. Na região sudoeste do Brasil, a floresta tropical expandiu sob condições climáticas quentes e úmidas durante o Holoceno, mas foram drasticamente reduzidas com o tempo. Não obstante, os numerosos fragmentos remanescente

36. A produção do espaço urbano de Criciúma-SC e seus agentes de transformação / The production of urban Space and its agents of transformation in Criciúma-SC
This dissertation proposes to show the development of the urban production/reproduction space in the city of Criciúma in Santa Catarina through the analysis of the political, economical and social agents involved in this process. This research has as the central contribution the space conception of Henri Lefebvre and its expansion made by Ana Fani Alessandr
