Pesquisa em Educação Ambiental: compromisso com a vida

Different environmental disasters registered around the world and their consequences to nature and to the biodiversity, including the human beings, lead us to deal with nature’s mysteries and with our limits In controlling technological apparatus that make us proud enough to think that we can control nature’s processes. These kinds of experiences, considered as a real “being-event”, make us experiment processes of disillusion related to the possibilities of science and technology. Considering this frame and the historical human experiences, one fundamental question is related to our position, our professional and ethical commitments and our responsibilities facing this reality. How can we deal with these facts that are continuously announcing the limits of nature, of science, technologies and our self-limits? As researchers involved with environmental education, it seems plausible for us to ask about the ethical commitments related to our “acts” of investigation. So, considering different and stimulating possibilities opened by intellectual and philosophers who are adding significant contributions to these debates, my proposal for this essay is to invite environmental education researchers to carry on a dialog involving these questions with some perspectives proposed specially by Bakhtin (1895 – 1975) and some other authors affiliated or not to his approach. This seems to be an opportunity which allows us to realize that our commitments as environmental education researchers would be identified with our commitments with life

Caldecott, Kipling, Rossetti: textos infantis vitorianos

Through brief comments on famous texts of Randolph Caldecott, Rudyard Kipling and Christina Rossetti, we intend to show to the reader aspects of children’s literature written in the reign of Queen Victoria (1837-1901), in which authors inherited the Romantic idea that child and childhood are pure, close to nature in a way that the adult man is not. Moralizing texts, they taught children how to be an adult.

Diagnóstico e proposição de medidas para o controle das perdas de água no sistema de abastecimento de Guaratinguetá

Over the past two years, Brazil has been facing a major water crisis in its history and the state of Sao Paulo is the one that has been going through worst difficulties. In this scenario, all water users should do everything possible so that the consumption of water resources is carried out in a sustainable manner. In this context, the companies responsible for the public water supply must increase the efficiency of water resource management. It is indispensable combating losses in the public supply system. When there is a non-visible leak in a pipe, the wastewater volume can be high, but in this case, the water returns to nature and continues to participate in the hydrological cycle. The economic loss corresponds to the value added to the product water, which includes the intrinsic costs of exploration, processing and distribution. This damage results in a reduced availability of financial resources of sanitation companies to invest in environmentally friendly solutions. This study aimed to diagnose the water distribution system in the city of Guaratinguetá (SP), held by the Companhia de Serviços de Água, Esgoto e Resíduos de Guaratinguetá (SAEG), to propose measures to combat water loss. Among the proposed measures, there is the monitoring of losses, planning for replacement of old pipes and company awareness as a whole in relation to combat water losses

La costruzione razionale della casa. Scritti e progetti di Giuseppe Pagano

The rational construction of the house. The writings and projects of Giuseppe Pagano Description, themes and research objectives The research aims at analysing the architecture of Giuseppe Pagano, which focuses on the theme of dwelling, through the reading of 3 of his house projects. On the one hand, these projects represent “minor” works not thoroughly known by Pagano’s contemporary critics; on the other they emphasise a particular methodological approach, which serves the author to explore a theme closely linked to his theoretical thought. The house project is a key to Pagano’s research, given its ties to the socio-cultural and political conditions in which the architect was working, so that it becomes a mirror of one of his specific and theoretical path, always in a state of becoming. Pagano understands architecture as a “servant of the human being”, subject to a “utilitarian slavery” since it is a clear, essential and “modest” answer to specific human needs, free from aprioristic aesthetic and formal choices. It is a rational architecture in sensu stricto; it constitutes a perfect synthesis between cause and effect and between function and form. The house needs to accommodate these principles because it is closely intertwined with human needs and intimately linked to a specific place, climatic conditions and technical and economical possibilities. Besides, differently from his public and common masterpieces such as the Palazzo Gualino, the Istituto di Fisica and the Università Commerciale Bocconi, the house projects are representative of a precise project will, which is expressed in a more authentic way, partially freed from political influences and dogmatic preoccupations and, therefore, far from the attempt to research a specific expressive language. I believe that the house project better represents that “ingenuity”, freshness and “sincerity” that Pagano identifies with the minor architecture, thereby revealing a more authentic expression of his understanding of a project. Therefore, the thesis, by tracing the theoretical research of Pagano through the analysis of some of his designed and built works, attempts to identify a specific methodological approach to Pagano’s project, which, developed through time, achieves a certain clarity in the 1930s. In fact, this methodological approach becomes more evident in his last projects, mainly regarding the house and the urban space. These reflect the attempt to respond to the new social needs and, at the same time, they also are an expression of a freer idea of built architecture, closely linked with the place and with the human being who dwells it. The three chosen projects (Villa Colli, La Casa a struttura d’acciaio and Villa Caraccio) make Pagano facing different places, different customers and different economic and technical conditions, which, given the author’s biography, correspond to important historical and political conditions. This is the reason why the projects become apparently distant works, both linguistically and conceptually, to the point that one can define them as ”eclectic”. However, I argue that this eclecticism is actually an added value to the architectural work of Pagano, steaming from the use of a method which, having as a basis the postulate of a rational architecture as essence and logic of building, finds specific variations depending on the multiple variables to be addressed by the project. This is the methodological heritage that Pagano learns from the tradition, especially that of the rural residential architecture, defined by Pagano as a “dictionary of the building logic of man”, as an “a-stylistic background”. For Pagano this traditional architecture is a clear expression of the relationships between a theme and its development, an architectural “fact” that is resolved with purely technical and utilitarian aims and with a spontaneous development far from any aprioristic theoretical principle. Architecture, therefore, cannot be an invention for Pagano and the personal contribution of each architect has to consider his/her close relationship with the specific historical context, place and new building methods. These are basic principles in the methodological approach that drives a great deal of his research and that also permits his thought to be modern. I argue that both ongoing and new collaborations with younger protagonists of the culture and architecture of the period are significant for the development of his methodology. These encounters represent the will to spread his own understanding of the “new architecture” as well as a way of self-renewal by confronting the self with new themes and realities and by learning from his collaborators. Thesis’ outline The thesis is divided in two principal parts, each articulated in four chapters attempting to offer a new reading of the theory and work of Pagano by emphasising the central themes of the research. The first chapter is an introduction to the thesis and to the theme of the rational house, as understood and developed in its typological and technical aspects by Pagano and by other protagonists of the Italian rationalism of the 1930s. Here the attention is on two different aspects defining, according to Pagano, the house project: on the one hand, the typological renewal, aimed at defining a “standard form” as a clear and essential answer to certain needs and variables of the project leading to different formal expressions. On the other, it focuses on the building, understood as a technique to “produce” architecture, where new technologies and new materials are not merely tools but also essential elements of the architectural work. In this way the villa becomes different from the theme of the common house or from that of the minimalist house, by using rules in the choice of material and in the techniques that are every time different depending on the theme under exploration and on the contingency of place. It is also visible the rigorous rationalism that distinguishes the author's appropriation of certain themes of rural architecture. The pages of “Casabella” and the events of the contemporary Triennali form the preliminary material for the writing of this chapter given that they are primary sources to individuate projects and writings produced by Pagano and contemporary architects on this theme. These writings and projects, when compared, reconstruct the evolution of the idea of the rational house and, specifically, of the personal research of Pagano. The second part regards the reading of three of Pagano’s projects of houses as a built verification of his theories. This section constitutes the central part of the thesis since it is aimed at detecting a specific methodological approach showing a theoretical and ideological evolution expressed in the vast edited literature. The three projects that have been chosen explore the theme of the house, looking at various research themes that the author proposes and that find continuity in the affirmation of a specific rationalism, focussed on concepts such as essentiality, utility, functionality and building honesty. These concepts guide the thought and the activities of Pagano, also reflecting a social and cultural period. The projects span from the theme of the villa moderna, Villa Colli, which, inspired by the architecture of North Europe, anticipates a specific rationalism of Pagano based on rigour, simplicity and essentiality, to the theme of the common house, Casa a struttura d’acciaio, la casa del domani, which ponders on the definition of new living spaces and, moreover, on new concepts of standardisation, economical efficiency and new materials responding to the changing needs of the modern society. Finally, the third project returns to the theme of the, Villa Caraccio, revisiting it with new perspectives. These perspectives find in the solution of the open plant, in the openness to nature and landscape and in the revisiting of materials and local building systems that idea of the freed house, which express clearly a new theoretical thought. Methodology It needs to be noted that due to the lack of an official Archive of Pagano’s work, the analysis of his work has been difficult and this explains the necessity to read the articles and the drawings published in the pages of «Casabella» and «Domus». As for the projects of Villa Colli and Casa a struttura d’acciaio, parts of the original drawings have been consulted. These drawings are not published and are kept in private archives of the collaborators of Pagano. The consultation of these documents has permitted the analysis of the cited works, which have been subject to a more complete reading following the different proposed solutions, which have permitted to understand the project path. The projects are analysed thought the method of comparison and critical reading which, specifically, means graphical elaborations and analytical schemes, mostly reconstructed on the basis of original projects but, where possible, also on a photographic investigation. The focus is on the project theme which, beginning with a specific living (dwelling) typology, finds variations because of the historico-political context in which Pagano is embedded and which partially shapes his research and theoretical thought, then translated in the built work. The analysis of the work follows, beginning, where possible, from a reconstruction of the evolution of the project as elaborated on the basis of the original documents and ending on an analysis of the constructive principles and composition. This second phase employs a methodology proposed by Pagano in his article Piante di ville, which, as expected, focuses on the plant as essential tool to identify the “true practical and poetic qualities of the construction”(Pagano, «Costruzioni-Casabella», 1940, p. 2). The reading of the project is integrated with the constructive analyses related to the technical aspects of the house which, in the case of Casa a struttura d’acciaio, play an important role in the project, while in Villa Colli and in Villa Caraccio are principally linked to the choice of materials for the construction of the different architectural elements. These are nonetheless key factors in the composition of the work. Future work could extend this reading to other house projects to deepen the research that could be completed with the consultation of Archival materials, which are missing at present. Finally, in the appendix I present a critical selection of the Pagano’s writings, which recall the themes discussed and embodied by the three projects. The texts have been selected among the articles published in Casabella and in other journals, completing the reading of the project work which cannot be detached from his theoretical thought. Moving from theory to project, we follow a path that brings us to define and deepen the central theme of the thesis: rational building as the principal feature of the architectural research of Pagano, which is paraphrased in multiple ways in his designed and built works.

Die Entwicklung der Mesofauna eines Weinberges im nordöstlichen Rheinhessen im Vergleich zum Lennebergwald und weiteren Agrarflächen

ZusammenfassungrnrnrnDer Köderstreifentest, die Auswertung der Minicontainer und die Erfassung der Bodenlebewesen mit Hilfe der Bodenstechkerne ergeben zusammen eine gut standardisierte Methode zur Darstellung und Beurteilung der Mesofauna. Unter der Vorraussetzung gleicher abiotischer Faktoren ist es problemlos möglich, selbst unterschiedliche Standorte wie Agrarflächen, Weinberge und Waldböden vergleichend zu untersuchen.rnrnAuf den verschiedenen Versuchsflächen des Laubenheimer Weinberges gelingt es deutlich zu zeigen, wie wichtig eine naturnahe Begrünung für den Boden ist. Dies betrifft nicht nur die Entwicklung der Humusschicht und damit die Bodenlebewesen, sondern auch die Schaffung von Kapillaren und Poren, die durch schwere landwirtschaftliche Geräte im Rahmen der Bo-denverdichtung reduziert werden. Erosionserscheinungen kommen vollständig zum Stillstand. Das Ökosystem Boden sollte auch so gut wie keine Belastung durch Herbizide, Insektizide und Pestizide erfahren. Ähnliches gilt auch für agrarisch genutzte Flächen. rnrnDer Lennebergwald als Naherholungsregion von Mainz ist besonders schützenswert, da dieser durch intensiven Immissionseintrag aufgrund der Nähe zu den Autobahnen und durch die Eutrophierung über die Haustiere stark belastet wird. Die immer größere Ausdehnung des Siedlungsgebietes und die damit verbundene steigende Anzahl an Waldbesuchern, die durch Verlassen der vorgegebenen Wege den Boden zerstören, gefährden zusätzlich das Ökosystem.rnrnÜber Sinn und Zweck einer Flurbereinigung zu diskutieren ist hier nicht angebracht. Aus bo-denkundlicher Sicht ist sie nicht zu befürworten, da hiermit alle bodenbewahrenden Maßnah-men ignoriert werden. Wichtig ist es, bei den Landwirten Aufklärungsarbeit zu leisten, was bodenschonende und bodenweiterentwickelnde Bearbeitungsmethoden bedeuten. Mit Hilfe sachgemäßer Aufklärung und richtiger Umsetzung kann durch Begrünungsmaßnahmen der zum Teil sehr stark strapazierte Boden erhalten, gefördert und auf lange Sicht stabilisiert wer-den.rnrnAufgrund der festgestellten Tatsachen wurde ab 2008 auf eine flächige Dauerbegrünung um-gestellt, so dass es auch in den unbegrünten Rebzeilen zu einer Bodenverbesserung kommen kann. Mit großer Wahrscheinlichkeit dürfte diese schneller voranschreiten, da die Mesofauna von den benachbarten begrünten Rebzeilen einwandern kann. rnDie Mesofauna landwirtschaftlich genutzter Flächen und Waldgebiete kann, obwohl extrem unterschiedlich, miteinander verglichen werden.rnrnBrachflächen und Waldgebiete lassen sich aufgrund der unberührten Bodenstrukturen sogar gut miteinander vergleichen. Temperatur- und Niederschlagsverhältnisse müssen dabei über-einstimmen. Die Azidität der jeweiligen Böden gilt es zu berücksichtigen, da verschiedene Tiergruppen damit unterschiedlich umgehen. Collembolen bevorzugen neutrale Böden, wäh-rend Acari als Räuber mit den Lebewesen in sauren Böden besser zurechtkommen. Die Streu-auflage ist dabei von großer Bedeutung.rnrnIm Rahmen von Bearbeitungsmaßnahmen kommt es durch jeglichen Maschineneinsatz zu ei-ner mehr oder weniger starken Veränderung der Bodenstruktur und somit auch der darin le-benden Mesofauna. Bis sich diese erholt hat, steht meist schon die nächste Bodenbewirtschaf-tung an. Die Bodenverdichtung spielt auch eine Rolle. Bei herkömmlichem Ackerbau ist eine Fruchtfolge mit eingeschalteter Brache oder Gründüngung mit Klee oder Luzerne angebracht, um die Mesofauna nicht zu stark zu strapazieren. Organische Düngegaben leicht abbaubarer Streu sind deutlich zu bevorzugen gegenüber sehr zellulose- und ligninhaltigen Pflanzenresten. Die Einbringung von Stoppeln nach Aberntung von Getreidefeldern ist sinnvoll, solange dabei nicht zu tief in die Bodenstruktur eingegriffen wird (ZIMMER 1997).rnrnIm Rahmen der Sonderkultur Wein, bei der eine Bodenbearbeitung aus den aufgezeigten Gründen eigentlich nicht notwendig wäre, sind Dauerbegrünungsmaßnahmen generell von Nutzen: der Erosion wird vorgebeugt, die Bodenfeuchte konstant gehalten, der anfallende Mulch als Gründüngung genutzt. Dies sind alles entscheidende Faktoren, die die Meso- und Makrofauna fördern. Nur die Bodenverdichtung durch schweres Gerät, wie Schlepper und Vollernter, sind für den Boden nicht förderlich (HEISLER 1993, EHRENSBERGER 1993). Nie-derdruckreifen und Verringerung der Befahrung sind geeignete Gegenmaßnahmen. rnrnEntgegen landläufiger Winzermeinung, stellen die Pflanzen einer Begrünung eigentlich keine Konkurrenz für die Weinstöcke dar. Die Vorteile einer Begrünung sind nicht nur die Förde-rung der einheimischen Flora in ihrem standortgerechten Artenreichtum, sondern auch Ver-vielfältigung von Meso- und Makrofauna aufgrund der dadurch mehr anfallenden und ein-zuarbeitenden leicht abbaubaren Streu (GRIEBEL 1995).rn

Permutation-based stochastic ordering using pairwise comparisons

The topic of this work concerns nonparametric permutation-based methods aiming to find a ranking (stochastic ordering) of a given set of groups (populations), gathering together information from multiple variables under more than one experimental designs. The problem of ranking populations arises in several fields of science from the need of comparing G>2 given groups or treatments when the main goal is to find an order while taking into account several aspects. As it can be imagined, this problem is not only of theoretical interest but it also has a recognised relevance in several fields, such as industrial experiments or behavioural sciences, and this is reflected by the vast literature on the topic, although sometimes the problem is associated with different keywords such as: "stochastic ordering", "ranking", "construction of composite indices" etc., or even "ranking probabilities" outside of the strictly-speaking statistical literature. The properties of the proposed method are empirically evaluated by means of an extensive simulation study, where several aspects of interest are let to vary within a reasonable practical range. These aspects comprise: sample size, number of variables, number of groups, and distribution of noise/error. The flexibility of the approach lies mainly in the several available choices for the test-statistic and in the different types of experimental design that can be analysed. This render the method able to be tailored to the specific problem and the to nature of the data at hand. To perform the analyses an R package called SOUP (Stochastic Ordering Using Permutations) has been written and it is available on CRAN.

Effects of forest management on ground-dwelling beetles (Coleoptera; Carabidae, Staphylinidae) in Central Europe are mainly mediated by changes in forest structure

Forest management is known to influence species diversity of various taxa but inconsistent or even contrasting effects are reported for arthropods. Regional differences in management as well as differences in regional species pools might be responsible for these inconsistencies, but, inter-regional replicated studies that account for regional variability are rare. We investigated the effect of forest type on the abundance, diversity, community structure and composition of two important ground-dwelling beetle families, Carabidae and Staphylinidae, in 149 forest stands distributed over three regions in Germany. In particular we focused on recent forestry history, stand age and dominant tree species, in addition to a number of environmental descriptors. Overall management effects on beetle communities were small and mainly mediated by structural habitat parameters such as the cover of forest canopy or the plant diversity on forest stands. The general response of both beetle taxa to forest management was similar in all regions: abundance and species richness of beetles was higher in older than in younger stands and species richness was lower in unmanaged than in managed stands. The abundance ratio of forest species-to-open habitat species differed between regions, but generally increased from young to old stands, from coniferous to deciduous stands and from managed to unmanaged stands. The response of both beetle families to dominant tree species was variable among regions and staphylinid richness varied in the response to recent forestry history. Our results suggest that current forest management practices change the composition of ground-dwelling beetle communities mainly by favoring generalists and open habitat species. To protect important forest beetle communities and thus the ecosystem functions and services provided by them, we suggest to shelter remaining ancient forests and to develop near-to-nature management strategies by prolonging rotation periods and increasing structural diversity of managed forests. Possible geographic variations in the response of beetle communities need to be considered in conservation-orientated forest management strategies.

Interpretation of fluid inclusions in quartz deformed by weak ductile shearing: reconstruction of differential stress magnitudes and pre-deformation fluid properties

A well developed theoretical framework is available in which paleofluid properties, such as chemical composition and density, can be reconstructed from fluid inclusions in minerals that have undergone no ductile deformation. The present study extends this framework to encompass fluid inclusions hosted by quartz that has undergone weak ductile deformation following fluid entrapment. Recent experiments have shown that such deformation causes inclusions to become dismembered into clusters of irregularly shaped relict inclusions surrounded by planar arrays of tiny, new-formed (neonate) inclusions. Comparison of the experimental samples with a naturally sheared quartz vein from Grimsel Pass, Aar Massif, Central Alps, Switzerland, reveals striking similarities. This strong concordance justifies applying the experimentally derived rules of fluid inclusion behaviour to nature. Thus, planar arrays of dismembered inclusions defining cleavage planes in quartz may be taken as diagnostic of small amounts of intracrystalline strain. Deformed inclusions preserve their pre-deformation concentration ratios of gases to electrolytes, but their H2O contents typically have changed. Morphologically intact inclusions, in contrast, preserve the pre-deformation composition and density of their originally trapped fluid. The orientation of the maximum principal compressive stress (σ1σ1) at the time of shear deformation can be derived from the pole to the cleavage plane within which the dismembered inclusions are aligned. Finally, the density of neonate inclusions is commensurate with the pressure value of σ1σ1 at the temperature and time of deformation. This last rule offers a means to estimate magnitudes of shear stresses from fluid inclusion studies. Application of this new paleopiezometer approach to the Grimsel vein yields a differential stress (σ1–σ3σ1–σ3) of ∼300 MPa∼300 MPa at View the MathML source390±30°C during late Miocene NNW–SSE orogenic shortening and regional uplift of the Aar Massif. This differential stress resulted in strain-hardening of the quartz at very low total strain (<5%<5%) while nearby shear zones were accommodating significant displacements. Further implementation of these experimentally derived rules should provide new insight into processes of fluid–rock interaction in the ductile regime within the Earth's crust.

"Teens talk healthy weight": A video technology project

Purpose. The purpose of this study was to investigate the impact of a motivational weight management DVD on knowledge of obesity related diseases, readiness, motivation, and self-efficacy to lose weight, connectedness to their care provider, and patients return to clinic. Design. A randomized control trial was conducted in which 40 overweight/obese adolescents and their parents/caregivers were randomly assigned to standard care alone or standard care plus DVD. Subjects completed a set of pre- and post-questionnaire measures. A group of 22 patients was also formed as a historical control group in order to account for the potential effect of extra attention given to subjects prospectively enrolled. Methods. The adolescents and their parent/caregiver were placed into a patient room. Consent was obtained and a set of written pre-questionnaires were given to both the parent and the adolescent. Standard care was provided to all patients by the Registered Dietitian and physician; the DVD was shown in addition to standard care among the intervention group. A set of post-questionnaires were given and compensation was provided. Analysis. Groups were compared to determine equivalence at baseline. Analysis of covariance was used to evaluate changes over time, while controlling for pre-test scores and race/ethnicity. Results. Parents who viewed the DVD experienced greater changes in correct knowledge as compared to parents who did not view the DVD. Conclusion. Our study found only one substantial benefit of the DVD beyond standard clinical practices. This is an important area for change as it increased awareness of obesity as a serious disease and has future clinical implications.^

Epiphytic orchid diversity and community composition in managed and natural moist evergreen Afromontane forest in SW Ethiopia

In SW Ethiopia, the moist evergreen Afromontane forest has become extremely fragmented and most of the remnants are intensively managed for coffee cultivation (Coffea arabica), with considerable impacts on biodiversity and ecosystem functioning. Because epiphytic orchids are potential indicators for forest quality and a proxy for overall forest biodiversity, we assessed the effect of forest management and forest fragmentation on epiphytic orchid diversity. We selected managed forest sites from both large and small forest remnants and compared their epiphytic orchid diversity with the diversity of natural unfragmented forest. We surveyed 339 canopy trees using rope climbing techniques. Orchid richness decreased and community composition changed, from the natural unfragmented forest, over the large managed forest fragments to the small managed forest fragments. This indicates that both forest management and fragmentation contribute to the loss of epiphytic orchids. Both the removal of large canopy trees typical for coffee management, and the occurrence of edge effects accompanying forest fragmentation are likely responsible for species loss and community composition changes. Even though some endangered orchid species persist even in the smallest fragments, large managed forest fragments are better options for the conservation of epiphytic orchids than small managed forests. Our results ultimately show that even though shade coffee cultivation is considered as a close-to-nature practice and is promoted as biodiversity conservation friendly, it cannot compete with the epiphytic orchid conservation benefit generated by unmanaged moist evergreen Afromontane forests.

Hacia una transformación económica de la Patagonia Austral : La actividad turística en la nueva dinámica productiva y su impacto en el empleo

El presente trabajo deriva de estudios realizados anteriormente sobre la caracterización económica de la Provincia de Santa Cruz. En dicho contexto se releva a la actividad turística como emergente de una nueva dinámica productiva. La estructura económica provincial se ha basado históricamente en el sector primario, con preponderancia del agregado 'minas y canteras' -en especial la rama petrolera-. Destacan en dicha actividad sus características de enclave y de recurso agotable. En la actualidad se observa un importante flujo de inversiones públicas -y en menor medida privadas-, las que impactarán a futuro en el desarrollo económico provincial. Las obras de infraestructura en ejecución propenden a dotar a la provincia de mejores condiciones de competitividad, favoreciendo la diversificación de sus actividades. En ese contexto emerge la actividad turística con gran dinamismo y evidenciando un enorme potencial, especialmente a partir de las nuevas condiciones macroeconómicas derivadas de la crisis devaluatoria del año 2001. El principal atractivo se centra en el producto 'glaciares'. Sin embargo, la región cuenta también con muchos otros vinculados a la naturaleza, que favorecen el desarrollo de nuevas dimensiones de la actividad turística, tales como el turismo de intereses especiales, científico, cultural, de aventura. La ciudad de El Calafate, localizada en el Departamento de Lago Argentino, se constituye en el epicentro de la región. El flujo de inversiones recibido, ha generado en los últimos años un significativo incremento de la actividad, repercutiendo en el empleo vinculado al sector; el cual posee características de extrema particularidad. Surge como objetivo del presente trabajo el análisis del sector turístico provincial y su vinculación con el empleo, así como también de los aspectos a tener en cuenta para su desarrollo sustentable en el tiempo. Resulta necesario analizar tanto las ventajas comparativas existentes como los problemas estructurales que enfrenta el sector para lograr condiciones de competitividad en el mercado turístico mundial. Por otra parte, el análisis de la morfología de la estructura empresarial permite comprender más acabadamente las formas de contratación existentes y su proyección en el tiempo
