RESUMO: O crescente movimento de geoconservação tem, por um lado, o objetivo de salientar patrimônios geológicos pontuais, em geral em locais distantes das cidades, porém mostra-se, por outro, como uma metodologia de enculturação para os assuntos da Terra. O tema central deste trabalho aborda a possibilidade da conservação geológica em ambientes urbanos como método de enculturação. Salienta-se o papel da Geologia Urbana para a gestão ambiental das cidades, a qual está emoldurada pelo gigantismo urbano atual e suas relações com as esferas planetária e local. Dado o gigantismo urbano contemporâneo, coloca-se a necessidade de restabelecer-se elos cognitivos entre à dinâmica do planeta, da paisagem e dos cidadãos. Como as cidades capturam a atenção humana em demasia, cortando os elos com o ambiente natural, a possibilidade de se introduzir elementos das ciências da Terra no âmbito da cultura pode contribuir com a noção de que a civilização urbana contemporânea é parte do sistema Terra. ...

Resumo: O Parque Nacional Serra da Capivara, fundado em 1979 e sagrado Patrimônio Mundial da UNESCO em 1991, foi demarcado com o intuito de proteger a biodiversidade local e o vasto patrimônio arqueológico, que oferece evidências da ocupação primitiva da América do Sul no Pleistoceno. A área, em clima semiárido e solo pouco propício para a agricultura, exibe índices de desenvolvimento social muito baixos. O turismo motivado pelo PNSC seria uma alternativa para o desenvolvimento sustentável, não fosse a falta de investimentos do governo em sua manutenção. Baseando-se essencialmente nos potenciais de uso turístico e educativo-sem, no entanto, olvidar o valor científico-, foi feito um inventário e análise de 30 sítios geológicos, localizados dentro e fora dos limites do parque. Espera-se que, aliados ao valor arqueológico do local, e devidamente valorizados e interpretados, esses sítios adicionem valor geológico à área, alavancando o geoturismo e auxiliando o desenvolvimento sustentável na região. Palavras-chave: desenvolvimento sustentável, geodiversidade, patrimônio geológico, Parque Nacional Serra da Capivara, sítios geológicos. Abstract: The Serra da Capivara National Park (SCNP) was founded in 1979 to protect the local biodiversity and archaeological heritage. Its archaeological sites, which provide evidence of the early human occupation of South America, motivated its status of UNESCO's World Heritage as of 1991. However, its establishment displaced families (many without compensation), and prevented them from the culturally-based use of the local natural resources. Under the semi-arid climate with long droughts and unfavorable soil for agriculture, the region exhibits low social development indices. Tourism motivated by SCNP could boost sustainable development, as much as deterioration of the park could be prevented, if the government invested more. In order to help boost tourism in the area with the addition of the geological value, an inventory of geological sites was carried out, resulting in a list of 30 sites, within and outside the limits of the park. The inventory mainly considered the tourist and educational potentials of the sites, but the scientific value was not neglected whenever it stood out. Provided the sites in the inventory are properly managed and promoted, they might provide a much-needed additional value that will help increase tourism in the region of Serra da Capivara, thus enhancing sustainable development there as well.

Observation itineraries of paleontological and geological aspects in the façades and floors of buildings are very widespread in several places of the world and are currently present in Brazil. This urban geotourism allows people to get to know the geodiversity without having to be in the outcrop in situ. The Museum of Tomorrow, located in Praça Mauá, nº 1, downtown Rio de Janeiro, has an inner lining and part of the outer lining, a coloring lime varying from beige to ivory. This limestone, originating from the Jandaíra Formation, Upper Cretaceous of the Potiguar Basin, Northeast of Brazil, is full of fossils of gastropod molluscs. The present work describes the fossils found on the floor in and around the Museum of Tomorrow and proposes a geotouristic script and an explanatory folder. For the elaboration of the script, eight points were selected based on four aspects: a) quantity of fossils per slab, b) taxonomic diversity, c) better state of preservation of fossils, d) different type of fossilization, and e) paleoenvironmental differences. The fossils identified in the course are the following gastropod molluscs: Plesioptygmatis Böse, 1906 and Nerinea Deshayes, 1827 (Nerineidae), Tylostoma Sharpe, 1849 (Naticidae), Trochactaeon Meek, 1863 (Trochacteonidae) and Family Fasciolariidae (indeterminate genus). As the Museum of Tomorrow works on exhibitions related to past, present and future time, it is possible during the course to enter information on geological time and to discuss this topic more comprehensively. In addition, this script, along with the explanatory folder, will allow the mediators to develop the paleontological content in the guided tours of schools and the public in general, taking advantage of the space to diversify the scientific dissemination.

A relação entre o homem e o substrato geológico pode ser observada na paisagem que pode revelar as diferentes maneiras de apropriação cultural dos elementos da geodiversidade. Os produtos dessa relação registram, em alguns casos, trechos importantes da história humana, tornando-os patrimônios geoculturais de grande valor histórico, científico e turístico. O processo de desenvolvimento do Brasil colonial e imperial teve papel preponderante na produção do patrimônio geocultural de Minas Gerais, guardando traços de um período em que a geodiversidade ocupou função relevante para o crescimento econômico regional. Este período, conhecido como ciclo do ouro, deixou na paisagem vestígios da mineração de metais preciosos e da metalurgia em ruínas de construções rudimentares e coloniais. Estes vestígios integram significativamente a paisagem da Serra da Calçada, localizada na porção noroeste do Quadrilátero Ferrífero, importante pólo minerário nacional. A fim de compreender melhor o potencial geoturístico destas áreas, foi proposto um método de quantificação desses elementos que integram o patrimônio geoculturalbuscando auxiliar na tomada de decisões relacionada à sua valorização e à geoconservação. I ntr odução O desenvolvimento da humanidade foi responsável pela produção de uma paisagem cultural que, ao longo da evolução humana na Terra, deixou vestígios da apropriação de elementos da natureza para construção de bens culturais de variados períodos históricos. Estas impressões culturais, que segundo Santos (1978, 2004), compõe a morfologia da paisagem, onde os produtos de diferentes momentos históricos se cristalizam no espaço geográfico criando formas-objeto ou rugosidades. O evidente aspecto da ação humana sobre a crosta terrestre é principalmente a modificação do relevo. Peloggia (2005) apud Pereira (2010) aponta que as intervenções na paisagem natural tiveram início com o domínio do fogo e se intensificaram com o surgirmento das civilizações, provenientes da Revolução Neolítica. Na geologia esta ocasião marca o início do Tecnógeno, período em que o homem passou a exercer forte influência na dinâmica externa do planeta. Para Pereira (2010) no Tecnógeno a espécie humana passa a ser um agente geológico, disseminando um estilo de vida urbanizado, construindo paisagens com significativas transformações na superfície terrestre. Assim como ressaltam Nascimento e Scifoni (2010) & Bento (2012), a relação sociedade-natureza é responsável pela produção de dois tipos de objetos culturais que se expressam na paisagem: os materiais, que constituem as cidades, as edificações e as plantações; e os imateriais, correspondentes às festividades, crenças, lendas, tradições, aos símbolos, entre outros, sendo ambos concebidos por meio de uma construção social e histórica. Destarte, no contexto do processo de desenvolvimento do Brasil colonial e imperial, a paisagem teve forte influência da ação minerária no período conhecido como Ciclo do Ouro, deixando vestígios relevantes para se compreender a história do país. Este período histórico teve

The use of GIS tools for monitoring environmental and cultural heritage through digital terrain models and visual axis in order to ensure a local preservation and demonstrate the relevance to conservation. This conservation is to maintain the local as a tourist, cultural and historical place. Since the survey can be done in a digital platform, there is a new possibility to work for the preservation of the cultural and environmental heritage.

O desenvolvimento dos ideais conservacionistas e o surgimento de modalidades turísticas como o ecoturismo e o geoturismo ampliou o interesse das populações urbanas por áreas naturais. Esse acréscimo de visitação em áreas de preservação ambiental é positivo em relação à divulgação dos patrimônios biótico e abiótico. Contudo, o acesso a este tipo de atrativo é feito principalmente através de trilhas, e a intensificação da utilização das mesmas podem atuar como vetores de propagação de diversos desequilíbrios ambientais, tais como exposição, compactação e erosão do solo. Para entender estes processos de degradação de trilhas foi utilizada como área de estudo a trilha do Carteiro, localizada na APA Serra São José, no município de Tiradentes, Minas Gerais. A análise se baseou na utilização do método de Área Seccional Transversal (AST), e cálculo das taxas de compactação do solo no leito e nas bordas da trilha. Foram separados diversos pontos de controle ao longo da trilha, onde foi aplicada a metodologia proposta. Trechos da trilha foram analisados, obtendo-se os valores de perda de solo em centímetros quadrados e as taxas de compactação em megapascal. Palavras-chave: Trilhas, geoturismo, ast, erosão e compactação do solo. Abstract: SOIL DEGRADATION ALONG A TRAIL DESTINATION ATTRACTIVES OF THE SERRA DE SÃO JOSÉ GEOTOURISTIC MONUMENT, TIRADENTES COUNTY, MINAS GERAIS STATE, BRAZIL. The development of conservation ideal and the rise of tourist modalities such as ecotourism and geotourism increased the interest of urban populations for natural areas. This increase visitation in areas of environmental preservation is positive with respect to the disclosure of biotic and abiotic heritage. However, access to this type of attraction is mostly done through trails, and the increasing use of them can act as vectors for the spread of many environmental disturbances, such as exposure, compaction and soil erosion. To understand these processes of degradation of trails was used as the study area of the Carteiro trail, located at Serra São José Environmental Protection Area, in the Tiradentes county, Minas Gerais, Brazil. The analysis is based on the use of the method of Cross Sectional Area (CSA), and estimation of soil compaction in the bed and on the edges of the trail. Were separated several checkpoints along the trail, where the methodology proposed was applied. These sections were analyzed, yielding values of soil loss in square centimeters and compaction rates in megapascals.

The region of the Rif between Taounate and Mernissa straddles the Intrarif, Mesorif and Prerif forming the outer Rifain areas. The geomorphology of its landscape, as spectacular as it is diversified, gives it a rich geo-heritage that can attract investments that can initiate a socioeconomic takeoff. This heritage is often overlooked in current approaches to managing and exploiting environments. Our study focused on the identification and classification of different geosites according to the IGUL and geomorphosite assessment method modified and adapted to the context studied in order to identify their scientific, ecological and cultural values, aesthetic and economic. This study thus provided us with a database characterizing the local geodiversity represented by twenty-four inventoried geosites [1]. The results confirm that the region has a geodiversity whose importance influences not only the natural dynamics, but also the human heritage. The scientific value of geosites is, in fact, globally high and often combined with additional interests that are not negligible but poorly known and little or no exploited. Some of these sites have provided important fossil populations (lamellibranchs, ostracodes ...). The global value of the geosites made it possible to identify the most representative sites. A summary of the results proposed around a global value illustrated by maps and photos. The geosite assessment by weighting gives an overall value ranging from 0.27 to 0.87 with an average of 0.60 (Figure 1). Most hydrological, structural and geomorphological geosites have good average scientific and additional values; which reinforces their overall value. It also appears that large geosites are favored over small ones. Thus, the landscape and geomorphological characteristics make the Taounate-Mernissa region an ideal place for the development of geotourism and environmental education activities aimed at discovering links linking natural and cultural heritage. They should, therefore, be protected from irrational degradation and exploitation. In addition, the test and the criticism of the method used contribute to the development and the improvement of the bases of the adopted method in order to favor the development and the integration of the human and natural components.

Landform assemblages may be used to define sites of geomorphological interest which are resources for rural sustainability. This paper focuses on the valuation and significance of such sites in the context of one European internal border region, illustrated using a case study from the inland mountains of the Spanish-Portuguese border: the Serra do Larouco. The theoretical and methodological approach used includes the recognition, inventory and assessment of a preliminary list of twenty-eight sites. They comprise diverse granitic landforms which characterise the rural inland landscapes in the North West of the Iberian Peninsula. The results from the qualitative and quantitative assessments were the basis for a final selection of nine sites as significant land resources. An analysis of their key values supports the proposal of different use and management options to promote rural sustainability. A review of the methodology applied and the consideration of other case studies provide a means to interpret and discuss the regional and local significance of the selected sites. The conclusions emphasise the crucial role that values linked to landforms can play in little-known mountainous and rural border regions, suggesting a future research agenda.

RESUMO O presente trabalho trata do relato sobre um experimento realizado na denominada " Trilha do Lenheiro 1 " , localizada na Serra do Lenheiro, adjacências da cidade de São João Del Rei, MG, com o objetivo de produzir dados que possam servir de base para proteção, conservação e manejo das trilhas. A trilha monitorada tem como característica ser um local aberto para visitação de pessoas, circulação de veículos off-road, que ocasionam vários impactos, como pisoteio na vegetação, potencialização de processos erosivos no leito da trilha, entre outros desequilíbrios ambientais acarretados pelo uso indevido das trilhas e pela falta de gestão na área de estudo. Foi utilizada uma técnica de cálculo da Área da Seção Transversal para monitorar a perda e/ou acúmulo de sedimentos no leito da trilha, cujos resultados mostraram progressivo aprofundamento do leito, acarretando intensificação e processos erosivos concentrados, potencializando ainda mais os problemas verificados na trilha, e também constatou-se que em alguns pontos houve um acúmulo de sedimentos, sendo que tanto a perda quanto o acúmulo de sedimentos tem uma relação direta com a declividade e o tipo de solo local. Também utilizou-se de registros fotográficos para realizar uma análise comparativa entre duas épocas em que a trilha apresentava evidencias de processos erosivos e foi possível registrar a mudança drástica ocorrida no local. ABSTRACT This work deals presents an experiment called Lenheiro 1 Trail, located in Lenheiro Ridge, surrounding São João Del Rei City, Minas Gerais State, Brazil, in order to produce data that can serve as a basis for protection, conservation and management of trails. The trail has monitored such as an open place for people visitations, outstanding off-road vehicles, causing various impacts such as trampling vegetation, soil erosion in the bed of the trail area, among other environmental imbalances posed by improper use of trails. A calculation technique of the Cross Sectional Area was used to analyze the impact of erosion on the trail bed, whose results showed progressive deepening of the bed, resulting in intensified and concentrated erosion, increasing even more the problems encountered in the trail, and also found that in some places there was an accumulation of sediment, and both the loss and the accumulation of sediments has a direct relationship with the slope and the type of local soil. Also was performed the use of photographic records to conduct a comparative analysis between two times when the trail had evidence of erosive processes and it was possible to register a drastic change occurred on site.

This dissertation proposes that the current legal definition of springs, veredas and wetlands should be revised. The existing concepts applied to these hydrological systems are controversial, but at the same time have important legal implications. According to Law 12.651/2012 (Brazil 2012), marginal zones, as well as their surroundings, are entitled to protection as ‘Areas of Permanent Preservation’ - APP. Being defined as an APP area allows a differentiated protection regime, such as maintenance or restoration of the local vegetation. Intervention in APP areas, or the suppression of the local vegetation, is only possible in exceptional circumstances determined by the law. Brazil’s environmental legal framework has many different approaches and many different instruments, all of which aim to restrict the impacts on bodies of water and guide the reasonable use of these vital resources. However, there needs to be improvement in the application of these legal standards, better integration between national laws, and improved interaction between Brazil’s national laws and international treaties, such as the
Ramsar Convention. Springs, veredas and wetlands need to be better conceptualized in the law, which would help to inform decisions on human settlement and alternative land use. This paper proposes a revision of the concepts for springs, veredas and wetlands, as well as a methodology for their future definition, based on a case study of the Ecological Monitoring Station in Águas Emendadas (ESEC-AE) in Brazil’s Federal District. ESEC-AE is particularly relevant for this study, given its role as a meeting point between the Escudo Central hydrogeological system and the Tocantins and Paraná Basins surface hydrology network. ESEC-AE’s hydrological and ecological attributes, combined with its environmental functions, indicate its potential to be recognized as a Ramsar Site. Nevertheless, there are indications that the ESEC-AE wetlands are reducing in size. Further studies are required to determine the factors influencing the shrinkage and any possible mitigation / recovery measures. The reduction in the ESEC-AE wetlands is particularly concerning, given their hydrological importance.

The themes of geodiversity and geoconservation arise in the XXI century as contributions of geosciences to sustainable development. Due to gigantic urban realm, social and environmental collapses, and intense occupation of the geosphere, became urgent the culturalization of issues related to Earth, especially of their conservation. In this context, the geodiversity concepts and its ecosystems functions had been proposed as well as strategies and methodologies for applying geoconservation. Although older, geoconservation strategies gained ground in the environmental and patrimonial management from de 1990's. Since then, different methodological proposals had been constructed in order to provide technical and scientifically support for such actions. This paper presents methodological contributions to integrated assessment of geological units from the analysis of six thematic maps of Porto Alegre city and from the proposition of a matrix constituted by 12 geolandscape indicators applied to 22 local geological units. In addition, 11 geosites are linked in terms of geological itineraries that allow reflecting regional geological history. Finally, this study proposes the Geological Itineraries of Porto Alegre as a socioeducational technology that could help to connect citizens with
the landscape where they live. Thus, geoeducation and geoconservation may have importante roles in environmental management of crowded cities.

When considering the numerous events that have prohibited the development of scientific projects or caused destruction of outcrops, it is clear that there is rapidly increasing necessity to define a Brazilian Code of Conduct for geological fieldwork. In general, this destruction is attributed to lack of knowledge as to the relevance of geological sites. The aim of this Code of Conduct is to guide geologists to adopt good practices during geoscience activities. Proposed guidelines are based on Codes of Conduct from other countries, mainly Scotland and England, on situations described in papers and on the personal experience of the authors. In this paper 29 points are suggested, in order to guarantee that fieldwork is conducted in accordance with geoethics, geoconservation and sustainability values. The proposal is structured in three parts: (1) Behavior and practices in respect to local traditions and providing information to the population; (2) Measures to minimize degradation on outcrops; and (3) Safety. The proposal seeks to broaden the debate on the need for responsible behavior during fieldwork, in order to promote respect for geodiversity. Through this code, Brazilian geoscientists will be able to contribute to the conservation of geological heritage and of outcrops with special educational relevance.

There are numerous geological, geomorphological, hydrological and other phenomena from inanimate nature on the territory of the Republic of Macedonia. Due to their exceptional and rare characteristics, some of them are surely worth visiting and therefore deserve adequate treatment and protection. The site called “Pillow Lava" is located near the village of Miravci and it exhibits unique geological and geomorphological features. This paper will focus on the fundamental values of the site and adequate measures for its protection will also be suggested.

Geoheritage is commonly defined as unique components of abiotic nature or as a part of cultural heritage stemming from the influence of rocks, minerals, water or landforms on the development and lifestyle of a human (Brocx, Semeniuk 007). Apart from natural geological objects, geoheritage also encompasses mining heritage, stone in construction and architecture, cultural landscape, symbolism of precious stones, minerals in medicine, geological processes in mythology, the history of Earth sciences, etc. (Tab). In situ and ex situ geoheritage is protected (geoconservation), available for visiting (geotourism), and employed in didactics (geoeducation). Along with the concept of geoparks, UNESCO promotes geoheritage in the form of geo-products, marking the commercial direction in which to relay knowledge regarding geosciences (Dryglas, Miśkiewicz, 0). In global geoparks it is a part of regional identity and sustainable development, and constitutes an element of education (Tab.). Ethnogeology, a research discipline, has been proposed for description and research of relations between a man and abiotic nature (Kamen-Kaye 975). Such geological conditioning of cultural development is the subject of numerous, yet dispersed, scientific and popular science works. The paper presents a review and evaluation of the usefulness of such geo-cultural aspects in didactics within geoparks and other geotouristic attractions.

The Miño is the most important river in the NW Iberian Peninsula. When it flows through Ourense town (Spain), the attractiveness of the thermal springs hides the
importance of the fluvial potholes developed over bedrock. These forms reflect the strength of erosion processes, linked to fluvial incision over time. Potholes have an environmental, didactic, socio-economic and cultural potential. In order to promote their integration within territorial heritage, this research is focused on a place-based knowledge and practice. This study aimed to define the meanings and interests of fluvial potholes, regarding their sustainable uses as georesources and offering fit information for the key social actors to assist territorial development. An inventory of sculpted forms was carried out in an urban reach of the Miño River. After the site diagnosis and form characterisation, a set of fluvial potholes (82 cases) was identified within the thermal area. The assessment of the geomorphological and use/management interests delivered their values as resources for territorial sustainability. Ten potholes, selected from a preliminary list and identified through the methodology, have a potential for education, leisure and recreation. Actions designed to raise awareness of the interests and values of these geodiversity components are also presented.

The assessment of the geomorphological and use/management interests delivered their values as resources for territorial sustainability. Ten potholes, selected from a preliminary list and identified through the methodology, have a potential for education, leisure and recreation. Actions designed to raise awareness of the interests and values of these geodiversity components are also presented.
