A The research aimed to characterize the territorial identity of fish farming in the Hydrographic Basin of Branco and Colorado’s rivers in the state of Rondônia, identifying the productive organization and its territorial spatialization in 2008 and 2020. A semi-structured questionnaire was applied to fish farmers and identified through environmental licensing issued for distribution in the basin; the geostatistical kriging method was used to analyze the productive concentration. The time series presented a growth in tanks and area, going from 707 in 2008 to 2,441 in 2020. As for the installation of tanks, 60% of fish farmers use the pasture area and 40% the Permanent Preservation area. The most widely used crop system is the extensive one, with the major breeding of the species being the Colossoma macropomum. The main outlet is the State itself, where the production is traded at fairs, markets and slaughterhouses.

This study aimed to investigate the perception of tourists (TRs) and the local community (CL) about the positive and negative impacts of tourism in Cocalinho-MT, a city located on the middle course of the Araguaia River. We surveyed during the high season (July/2019) by applying a semi-structured questionnaire. Both the TRs and CL highlighted the positive economic impact of tourism. Concerning the negative impacts, both groups highlighted the environmental impact of tourism. The perception of tourism for TRs and CL pointed out impacts in the economic, social and environmental areas. Information like this can assist decision-makers in management strategies in the Cocalinho region and other similar tourist regions.

The semi-arid comprises singular dynamics represented by the adaptive capacity of vegetation and the provision of ecosystem services (ES) that, directly and indirectly, provide well-being to humanity. In this context, the objective was to identify the provision of ecosystem services in the semi-arid landscape of the Riacho São José Basin in Pernambuco according to the different classes of land cover. The methodology is based on the technical guidelines of the Common International Classification of Ecosystem Services, fieldwork, geographic information systems and RAW Graphs platform. Such procedures allowed the identification of 51 SE, of which 22 are provision, 19 with the function of regulation and maintenance and 10 of a cultural nature. Thus, the identification of SE in the basin comprises indicators that should guide the environmental planning and sustainable management of the Lands.
半干旱地区包括以植被适应能力和提供直接和间接为人类提供福祉的生态系统服务(ES)为代表的单一动态。在这种情况下，目标是根据不同的土地覆盖类别，确定在伯南布哥省Riacho s o jos盆地的半干旱景观中提供的生态系统服务。该方法基于国际生态系统服务共同分类的技术指南、实地调查、地理信息系统和RAW图形平台。通过这样的程序，可以确定51个SE，其中22个是提供功能，19个具有管理和维护功能，10个具有文化性质。因此，确定流域内东南东南的指标应指导土地的环境规划和可持续管理。

Relevant protagonist of Brazilian contemporary Art, Tunga built installations of provocative character that employed poetics and materials that are originated from telluric elements. This essay seeks to decipher geopoetic connections between earth and place as expressed in the metaphors of Tunga’s installations presented in Instituto Inhotin and at the 33th São Paulo Art Biannual. Based on the creative return in Geography and informed by the field of phenomenological studies, geopoetic expressions of ‘X-Estudo’ (2009) and ‘Sem Título’ [from ‘La Voie Humide’ Series] (2014) artworks in their capacity to unravel existential spaces. It is comprehended that cosmos expanded by earthly worlds elucidate interconnections at the hearth of primal relations to place. The subject-place-artwork reciprocity, thus, can potentialize understandings of the geographicality of being-in-the-world.

O artigo aborda a prática da vilegiatura e como ela redefine a dinâmica urbana de pequenas cidades, bem como seu papel na rede urbana. O foco do estudo esteve assentado em pequenas cidades serranas e litorâneas localizadas no nordeste brasileiro. Gravatá (PE), Guaramiranga (CE), Lagoa Nova (RN) e Tibau (RN) evidenciam este fenômeno nos últimos anos que mostra como a sociedade do lazer se apropria da praia e da serra estabelecendo fortes laços territoriais com espaços não-metropolitanos, concebendo fatores indispensáveis de conforto e comodidade impostos pela sociedade urbana. A Pesquisa foi construída por meio de consulta em acervos bibliográficos virtuais, livros e elaboração e análise de banco de dados estatísticos obtidos, em especial, do Instituto Brasileiro de Geografia e Estatística – IBGE, assim como trabalho de campo realizado nas cidades estudadas.

The aim of this paper was the mapping of the land cover classes in an area of the Delta do Parnaíba, Piauí, NE, Brazil using the unsupervised classification method in RapidEye images. Through digital processing of images in a GIS environment, it was possible to map 12 classes of land cover. The results showed that the highest percentage of the study area is covered by fields with the presence of shrub vegetation and a predominance of pasture. Other classes (mobile dunes and sandy shoreline, undergrowth and exposed land) characterize a high level of environmental vulnerability and risk of erosion, illustrating the need for sustainable management techniques. Based on the techniques and evaluation criterias, the mapping indicated very good agreement, emphasizing the quality of the visual interpretation of the image and the classification method employed.

The present study corresponds to a part of the project Symbolic Spaces of the Latin Carnival: Heritage Mapping of the Theatricality of Tourist Cities. The theme seeks an approach between geometric theory of fractals and the cognitive and conceptual mapping processes. It is intended to explore the possibilities of cultural analysis of allegories, such as scenic structures of carnival parades. The work brings together images from several South American countries in a comparative cultural approach. As the stages of the study show a recreation of faces of the figure of Rei Momo as a catalyst for collective creativity in several carnival cities in the continent. Firstly, by identifying cars and figures in fractal reading, after the conceptual indicators of power. Finally, it deepens comparative reflections regarding this theatricality in Momo's claims, in his South American national contexts.

No presente artigo pretendemos discutir as relações socioespaciais constituídas no âmbito do Sistema Integrado de Transportes de Fortaleza (SIT-FOR). Para fazê-lo, lançamos mão da categoria trabalho, compreendendo em uma perspectiva marxista que é a partir das relações de trabalho que mulheres e homens mediam sua relação com os demais elementos da natureza e se constituem como seres sociais. Nesse sentido, ao desvelar os papéis que o sistema de transporte cumpre nas cidades, como de assegurar a mobilidade da classe trabalhadora em direção aos locais de trabalho, não podemos deixar de perceber que também as contradições de classe engendradas no conflito entre motoristas de ônibus, cobradores e empresários do setor fazem parte do processo de (re)produção do espaço urbano em cidades como Fortaleza.

The hydrographic basin is an important instrument for the planning and management of water resources, being defined as an area bounded by water divisions formed by a main river and its tributaries. This work aims to understand the physiography and hydrology of the high course of the hydrographic basin of Santo Antônio, Ilha do Maranhão through morphometric analysis. This research has a theoretical and empirical character and in order to reach the objective, a bibliographic, cartographic and morphometric data survey was carried out, thematic maps were elaborated and field work was carried out. The morphometric data collected in the study area took into account the linear and sandy analysis and through the results achieved it was possible to better interpret the physiography and the hydrological behavior of the high course. These data can serve as a basis for monitoring this basin and analyzing areas subject to floods.

Soil erosion is a natural phenomenon that has been accelerated by inadequately human activities, resulting in soil degradation and its multiple functions. In this sense, the objective of this research work is to assess the environmental status of the drainage basin of Pequeno river, Paraty Municipality, Rio de Janeiro State, with emphasis on soil erosion. The methodological procedures involved bibliographical and documentary surveys, fieldwork, analysis of soil attributes and thematic mappings. The results show that the relief characteristics contribute to geomorphological processes acceleration and, despite the limitations, soils showed low erodibility. However, changes in vegetation cover and inadequate use and management have an influence on the supply of organic matter into the soil, which may affect its attributes and increase its erodibility over
