37. Analysis of Potential for Linear Erosion in the Cerrado Biome Using Morphopedology
ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units con

38. Population dynamics of the mud crab Panopeus austrobesus Williams, 1983 (Brachyura: Panopeidae) associated with a mussel farm at the southeastern Brazilian coast
Abstract Mussel farms are one of the most important modalities of aquaculture and constitute almost 80% of the total bivalve production in Brazil, representing about 5% of the national production. Brachyuran crabs are common inhabitants of these environments and represent an important link in coastal marine food chains. The aim of this investigation is to de

39. Mapping the dengue scientific landscape worldwide: a bibliometric and network analysis
BACKGROUND Despite the current global trend of reduction in the morbidity and mortality of neglected diseases, dengue’s incidence has increased and occurrence areas have expanded. Dengue also persists as a scientific and technological challenge since there is no effective treatment, vaccine, vector control or public health intervention. Combining bibliom

40. Ethnopedology of a Quilombola Community in Minas Gerais: Soils, Landscape, and Land Evaluation
ABSTRACT Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people

41. BIOMASS PYROLYSIS KINETICS: A REVIEW OF MOLECULAR-SCALE MODELING CONTRIBUTIONS
Abstract Decades of classical research on pyrolysis of lignocellulosic biomass has not yet produced a generalized formalism for design and prediction of reactor performance. Plagued by the limitations of experimental techniques such as thermogravimetric analysis (TGA) and extremely fast heating rates and low residence times to achieve high conversion to usef

42. Characterization and Classification of Soils under Forest and Pasture in an Agroextractivist Project in Eastern Amazonia
ABSTRACT: Knowledge of soils in the Amazon rainforest is becoming increasingly essential due to dynamics adopted by farmers that substitute forest for pastures, together with growing pressure from diverse segments of society towards adoption of sustainable production systems. The objective of this study was to characterize the soils along two toposequences,

43. 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

44. 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

45. 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

46. When Foreign Policy Meets Social Demands in Latin America
Abstract In order to introduce this special issue of Contexto Internacional, we first seek to provide a panoramic understanding of the Latin American political landscape. Next, we consider the new (and not so new) development strategies adopted by Latin American states, and their implications for foreign policy and international relations. Following this, we

48. 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
