This study deals with the Holocene environmental dynamics experienced by a seasonally wet-dry landscape of tropical Columbia. In light of a high ecological sensitivity, the study area is also analyzed as the resource of man. This is done by intensive study area reconnaissance, mapping, altimeter survey, and radiocarbon dating of fluvial landforms. Also, samples of soil, pasture, and water were collected for later study, and several interviews were completed with local residents. The study area is a tropical lowland of northcentral Columbia at about 7 ½° north attitude. A maximum local relief about 600 m is maintained by a rather resistant lower Tertiary sandstone hogback. The well-faulted landform lies at an almost vertical attitude because of its boundary with the great Salinas fault, which was probably active during the Tertiary-Quaternary orogeny of the Cordillera Oriental. Through this landscape flows the Río Lebrija, a major local base level at about 180 m elevation. Draining about 2700 km2 of the Cordillera’s western flank, this valley contains relict evidence of major ecological fluctuations during Quaternary time. Midway through the Holocene, a marked thinning of plant cover, caused by peak Hypsithemal temperatures and resulting precipitation irregularities, permitted intense surface erosion of hillslopes. This process, maximized by the initiation of short wet periods delivered considerable quantities of weathered materials to aggrading valleys. The sands and gravels deposited in areas protected from stream migration have formed the alluvia terraces seen today. Charcoal, collected from compact coarse sandy alluvium lying 15 m above the present Río Lebrija, was dated at 6.2535+90 and 5.365+85 B.P., a much younger date than suggested for correlative basin landforms. It appears that there is a need for reassessment of the assumed magnitude and rapidity of the recent, as well as ancient, dynamics undergone by tropical flora, erosion surfaces and fluvial systems. An important environmental concept appears to be a direct correlation between valley aggradation and progressive warmth in continental, tropical wet-dry regions. Man’s activities are naturally destructive to this sensitive low-land environment. Great earthflows dated at 445+110 B.P. may have resulted from European-type deforestation of unstable slopes. The denudation of these rugged slopes continues today at an expanding rate. The message is reinforced after every heavy rain when the swift Lebrija swirls red-brown with yesterday’s soil. The initiation of high protein agriculture on the rich pastured bottomlands might lessen the human pressures upon the most sensitive landscapes and would enhance possibilities for supplemental irrigation. Also, the powerful current of the Río Lebrija is a potential source of hydroelectric energy. The harnessing of this power by a proposed waterwheel-barrage facility would deal minimal alteration to the fluvial system, while supplying the community with limited irrigation and domestic energy. If successful, the utilization of land and water resources would be optimized, and the local people would be in a better position to adjust to weather anomalies initiated by an evolving environment. KEY WORDS: Colombia, Cordillera Oriental, tropical wet-dry climate, alluvial terrace, Hypsithemal “environmental flux,” and land use.

Species diversity varies dramatically across the surface of the Earth. A key step in the accumulation of species diversity is the ability of species to coexist in biological communities. Thus, identifying the mechanisms underlying community assembly is a major challenge for ecologists seeking to explain patterns in species diversity and composition. Recently some consensus has been reached on the set of processes that influence community assembly: speciation, demographic stochasticity, niche-based fitness trade-offs among species and dispersal. However, it is unclear how the importance of a particular process changes with spatial scale, which interactions exist among processes at large spatial scales and the extent to which niche-based resource partitioning among species explains differences in diversity among communities. Neotropical birds offer an ideal opportunity to address these uncertainties because of their high diversity and the existence of detailed information on their evolutionary history and ecology. In this thesis, I first use trait and phylogenetic metrics of community structure to show that both habitat filtering and interspecific competition shape community composition at the scale of individual bird territories (~1-2 ha). Second, I use simulations of community assembly to show that trait-based metrics of community structure outperform phylogenetic metrics for detecting niche-based community assembly, and that both sets of metrics often have low power when multiple processes influence community composition. Third, taking a trait-based, species-level approach, I show that both habitat filtering and interspecific competition influence species occurrence at regional scales (~75000 km²), and interact with dispersal ability so that their effect on species occurrence is increased for species with greater dispersal ability. Finally, using a combination of trait- and isotope-based methods to quantify resource partitioning, I show that species' niche widths do not change and niche overlap is reduced at high compared to low species richness. Taken together, these results suggest that both habitat filtering and interspecific competition (i.e. niche-based processes) influence community assembly from local to regional scales. However, at least at regional scales, the degree to which these processes are important for determining the occurrence of any given species depends on that species's dispersal ability. They also suggest, based on niche-based interspecific competition influencing community composition, that differences in species richness among communities are in part explained by differences among sites in the breadth of available niche space, not by increased ecological specialisation or niche overlap.

This diploma thesis called The Jesuit Arquitecture in South America focused on Andean area is treating the jesuit arquitecture in South America and it is focused on the arquitecture in towns in The Andean Area, now the states of Beru, Bolivia, Ecuador and Colombia. My final work has an intention to provide a summary of this fascinating part of the colonial history of art of Latin America. I tried to deal with the part of the jesuit history from the arrival of members of the Society of Jesus in the end ot the XVI. century to their expulsion in the year 1767. The content of this thesis is to present the jesuit arquitecture and to present their caracteristics and diferences from the european baroque arquitecture. I wanted to speak about the forms and technologies of the jesuit works and to compare them, to compare the jesuit buildings, which I am dealing with, between them and they are comparated with the itailan jesuit church called Il Gesù. At the end, I included the actual situation of the jesuit building in The Andean Area.

Commissions, comités, conseils, les instances spécialisées dans les questions d’éthique des sciences de la vie prennent de nombreuses dénominations et forment une nébuleuse extrêmement diverse. Riche est la littérature qui s’est donné pour objectif de différencier ces organes. Les diverses tentatives de typologie semblent s’accorder sur l’existence de deux comités d’éthique-types : les comités d’éthique clinique ou hospitaliers et les comités d’éthique de la recherche biomédicale. C’est à partir de ces catégories que seront créés de nombreux comités exerçant des compétences variées et agissant au niveau local, national, régional et international. S’agissant de leurs caractères principaux, la doctrine dégage trois éléments fondamentaux : l’indépendance, la pluridisciplinarité et le pluralisme. En dépit d’une évolution plus tardive dans le domaine des technologies, du progrès médical et plus généralement des sciences de la vie, l’Amérique Latine a pleinement pris part au phénomène dit d’institutionnalisation de la bioéthique ; non sans quelques spécificités. L’établissement des instances d’éthique dans cette région est caractérisé par la priorité accordée aux principes de justice et d’accès aux services de santé en raison de la prééminence des problèmes socio-économiques. / The organizations and authoritative entities specialized in evaluating the ethical issues raised by recent developments in the life sciences take on extremely diverse denominations and forms such as commissions, committees, and boards that all form acomplex nebulous. Research focusing on differentiating these bodies is very rich. Various attempts at categorizing these organizations agree on the existence of two main types ofethics committees, hospital ethics committees, and biomedical research ethics committees. On the basis of these categories numerous sub-committees are then created and exercise a variety of skills at the local, national, regional and international levels. As for their main characteristics, consensual research identifies three basic elements: independence,interdisciplinarity and pluralism. Despite a relatively late development in the general field of the life sciences and more particularly in the realm of technology and medical progress, Latin America has fully participated in the phenomenon now known as the institutionalization of bioethics, and has done so with specific characteristics to its region. Indeed, the establishment of ethical review boards in this region is above all preoccupied by the priority given to the principles of justice and access to health services due to the predominance of socio-economic issues.

En Amérique du Sud, on construit un système politico-normatif qui reconnait les collectivités locales comme acteurs du processus d’intégration régionale. Ce système émerge principalement d’une convergence spontanée et coordonnée. Des processus de décentralisation permettent l’action extérieure des collectivités dans le monde. Des initiatives d’intégration inter-étatique soutiennent la coopération entre les collectivités locales sud-américaines. La convergence de normes de décentralisation et d’intégration régionale fixe un cadre minimal pour la collaboration entre les collectivités de pays différents. On observe ainsi une augmentation de coopérations décentralisées. Les échanges entre les collectivités locales sont devenus naturels sur le plan politique, et légitimes sur le plan juridique. A partir d’une dynamique circulaire, les collectivités locales adaptent leurs administrations au « système de coopération territoriale » conçu par les Etats, et en même temps le perfectionnent par leurs pratiques. Au moins deux conséquences découlent du fonctionnement du système. Les collectivités locales ont la compétence de libre association sud-américaine. Elles appuient l’émergence ou la consolidation d’espaces transnationaux. Alors, un nouveau découpage territorial se dessine. Des espaces transfrontaliers et bi-océaniques cohabitent avec des territoires plus classiques, comme les municipalités, les régions ou les Etats. Cela constitue un apport des collectivités locales à l’intégration régionale. / Throughout South America, a political and legal system that recognizes local governments as actors of regional integration is under construction. This system mainly emerges from a spontaneous and coordinated convergence. Decentralization processes allow local governments to act externally, internationally. Inter-States integration initiatives support the cooperation between local authorities. Norms and rules for decentralization and for South American integration converge to set a minimum framework for the collaboration between local governments of different countries.An increase in decentralised cooperation is thus observed. Exchanges between local authorities have become natural on the political level, and legitimate on the legal level. Thanks to a circular dynamic, local governments adapt their administrations to the « territorial cooperation system » designed by States, and at the same time perfect it through their practices. At least two consequences flow from the system. Local authorities have the jurisdiction to free associationthroughout South America. They support the emergence or consolidation of transnational spaces. Then, a new territorial division emerges. Bi-oceanic and cross-border spaces coexist with more traditional territories, such as municipalities, regions or States. Therefore local authorities contribute to the regional integration in South America.

O objetivo deste estudo foi analisar a variabilidade climática espectral da temperatura da superfície do mar, TSM, global associada a oscilações de 1-12 meses, 1-2 anos, 2-4 anos, 4-8 anos e 8-12 anos, entre1854 e 2014, e, as possíveis relações com a variabilidade climática na América do Sul. A análise espectral da TSM foi obtida com a aplicação da técnica de ondeletas a dados mensais. Em termos globais, as bacias tropicais do Pacífico Norte e Sul apresentam os sinais mais intensos da variância de TSM, em todas as faixas espectrais consideradas, e, portanto, valores mais próximos da média global para os trópicos, indicando a importância do oceano Pacífico no clima global. Nesta ordem, as bacias do Pacífico Sul, Pacífico Norte, Atlântico Norte, Indico e Atlântico Sul apresentam valores decrescente de variância da TSM. A análise da tendência linear ao longo do período considerado mostra que, globalmente, fenômenos tropicais com oscilações nas escalas de frequências mais altas, 1-12 meses, 1-2 anos e 2-4 anos, têm apresentado decréscimo de energia e que fenômenos com oscilações nas escalas de frequências mais baixas, 4-8 e 8-12 anos, têm apresentado aumento de energia, o que sugere a troca de energia entre fenômenos de alta e baixa frequência . As oscilações de 2-4 anos e de 4-8 anos na região equatorial do Pacífico são as que apresentam os maiores valores de energia, em especial nas regiões de Ninõ1+2, Niño3, Niño3.4 e Niño4. Os resultados permitem verificar que eventos fortes de El Niño sempre estiveram associados a sinais intensos da variância de TSM nas faixas espectrais de 2-4 anos e 4-8 anos e que os eventos mais fracos de El Niño estiveram associados à faixa de oscilações mais rápidas, 1-2 anos. O início do aumento do valor da variância de TSM para oscilações de 2-4 anos e 4-8 anos na região equatorial do Pacífico apresenta, em todos os casos, antecedência significativa em relação à ocorrência de um evento de El Niño forte, indicando a possibilidade de usar este sinal como preditor da ocorrência de eventos quentes de ENOS. A associação entre a variabilidade da variância espectral de TSM e a variabilidade climática na América do Sul foi verificada com base nos dados precipitação do GPCC, dados de vento das reanálises I e II do NCEP-NCAR e da reanálise do JRA-55. A análise de ondeletas da TSM tropical para a faixa de oscilações de 4-8 anos possibilitou a divisão do período todo em fases distintas: fases positivas, 1948 a 1960 e 1982 a 2003 e fases negativas, 1961 a 1981 e 2004 a 2014. Observou-se que as fases positivas e negativas apresentam um padrão bipolar da precipitação entre as regiões nordeste e sudeste da América do Sul, o que está associado a anomalias contrárias da circulação atmosférica em altos e baixos níveis sobre a região central do continente, constituindo um resultado inédito na área de climatologia. As fases positivas da variância de TSM para oscilações de 4-8 anos estão associadas a anomalias negativas e positivas de precipitação, respectivamente, sobre as regiões nordeste e sudeste da América do Sul enquanto que as fases negativas estão associadas a padrões contrários. O padrão do 4º modo da Análise de Componentes Principais aplicada aos dados de vento em 200 hPa contribui para explicar fisicamente o padrão bipolar da precipitação observado no setor leste do continente na escala decadal, por meio da propagação de ondas de baixa frequência entre o Pacífico Sul e a América do Sul. / The aim of this study is to analyze the global SST spectral climate variability for 1-12 month, 1-2 year, 2-4 year, 4-8 year, and 8-12 year oscillations, in the period from 1854 to 2014, and the possible relations with the climatic variability in South America. The spectral analysis of SST was obtained with the application of the wavelet technique to the monthly data. In global terms, the North and South Pacific basins show the most intense signs of SST variance in all the spectral ranges considered, and therefore, values closer to the global average, indicating the importance of the Pacific Ocean in the global climate. Then, in order of importance, come the basins of the South Pacific, the North Pacific, the North Atlantic, the Indian Ocean and the South Atlantic. The analysis of the linear trend throughout the period considered shows that globally within the tropical range, phenomena with oscillations in the scales of higher frequencies, 1-12 months, 1-2 years, and 2-4 years, have decreased energy and that phenomena with oscillations at lower frequency scales, 4-8 and 8-12 years, have presented increased energy through the course of time, suggesting energy exchange between high frequency phenomena and low frequency phenomena. The 2-4 year and 4-8 year oscillations in the equatorial Pacific region are those with the highest energy values, especially in the Nin1 + 2, Niño3, Niño3.4 and Niño4 regions. It is also possible to verify that strong El Niño events have always been associated with intense SST variance signals in the 2-4 year and 4-8 year spectral bands, and the weaker El Niño events were associated with the 1-2 year spectral bands. The beginning of the increase in the SST variance value for 2-4 year and 4-8 year oscillations in the equatorial region of the Pacific presents, in all cases, significant antecedence in relation to the occurrence of a strong El Niño event, indicating the possibility of using this signal as a predictor of the occurrence of hot ENSO events. The association between SST spectral variance variability and climatic variability in South America was verified based on GPCC precipitation data and wind data from NCEP-NCAR I and II reanalyses and of the JRA-55 reanalysis. The analysis of tropical SST wavelets for the 4-8 year oscillation range allowed the division of the whole period into distinct phases: positive phases, 1948 to 1960 and 1982 to 2003; and negative phases, 1961 to 1981 and 2004 to 2014. It was observed that positive and negative phases present a bipolar precipitation pattern between the Northeast and Southeast regions of the AS, which is associated with anomalies of atmospheric circulation at high and low levels over the central region of the continent, which is an unprecedented result area of climatology. The positive phases of the SST variance for 4-8 year oscillations are associated with negative and positive precipitation anomalies respectively over the northeast and southeast regions of South America while the negative phases are associated with contrary precipitation patterns. The 4th mode pattern of the Principal Component Analysis applied to wind data at 200 hPa contributes to physically explaining the bipolar pattern of precipitation observed in the eastern sector of the continent on the decadal scale by propagating low frequency waves between the South Pacific and South America.

A interação entre troposfera e estratosfera tem grande influência e é de grande importância nos processos de ciclogênese em superfície. Entretanto, não se conhece exatamente a frequência destas interações e nem como podem influenciar na intensidade de ciclones em geral. Este trabalho tem como objetivo geral estudar como os altos níveis da atmosfera afetam o desenvolvimento de ciclones em superfície na América do Sul e Oceano Atlântico Sul, utilizando o conceito de vorticidade potencial (VP). Através de dados de ciclones rastreados em superfície e VP em 300 hPa desenvolveu-se um algoritmo que associa automaticamente os ciclones em superfície com anomalias de vorticidade potencial (AVP). Para o período 1998-2003, fez-se então a separação dos ciclones em associados (AAVP) e não-associados (NAVP) a AVP. De forma geral, observou-se que a maior parte dos ciclones AAVP concentra-se na região oceânica extratropical e os NAVP preferencialmente na região continental próximo de 30°S e em latitudes subtropicais. Para todo o período analisado, o número total de ciclones AAVP (55%) superou o número de NAVP (45%), sendo o ano de 2002 o único que apresentou número maior de eventos NAVP. Quanto à distribuição sazonal, os ciclones AAVP são mais frequentes nos meses de inverno e primavera, enquanto que os NAVP nos meses de verão. O tempo de vida dos NAVP é menor que dos AAVP, além de possuírem menor intensidade (de acordo com a pressão central média). Além destes fatores, a distância percorrida e a velocidade médias dos ciclones NAVP são menores do que dos AAVP. As composições dos campos sinóticos mostram que nos eventos NAVP, independente da estação do ano, a troposfera é mais quente que nos AAVP. Nos NAVP a forçante térmica é essencial para a formação do ciclone, enquanto que nos AAVP a AVP induz vorticidade ciclônica primeiro em altos níveis, que então se propaga para baixos níveis. Através da análise dos campos sinóticos, notou-se maior baroclinia nos casos NAVP, pois tanto os cavados em altos e médios níveis quanto a corrente de jato permanecem favorecendo o desenvolvimento do ciclone em superfície, enquanto que nos AAVP o centro do ciclone em superfície está verticalmente quase alinhado ao cavado. Centros de vorticidade relativa ciclônica em 500 hPa desprendem-se do escoamento de oeste em todas as estações para os casos AAVP, porém, no verão, isto também é visto nos NAVP. / The process of troposphere-stratosphere interaction has influence and is very important on surface cyclogenesis. However, the frequency of these interactions and how they influence the intensity of cyclones is not known exactly. The main objective of this work is to study how the upper levels affect the development of surface cyclones in South America and South Atlantic Ocean using the concept of potential vorticity (PV). Cyclone tracking data and 300 hPa PV were used to develop an algorithm that automatically associates the surface cyclones with potential vorticity anomaly (PVA). For the period 1998-2003, the cyclones were separated as associated (APVA) and non-associated (NPVA) with PVA. In general, it was observed that most of the APVA cyclone was concentrated in extratropical oceanic region, while NPVA cyclones form over the continent preferably around 30°S and subtropics. The total number of APVA cyclones (55%) exceeds the number of NPVA (45%), except for 2002. In regard to seasonal distribution, the APVA cyclones are more frequent in winter and spring months while NPVA in summer months. The lifetime of NPVA cyclones is shorter and they are less intense than APVA (according to the average central pressure). In addition to these factors, the mean traveled distance and mean velocity are smaller in the NPVA than in APVA. The composites of the synoptic fields show that in NPVA events, regardless of the season, the troposphere is warmer than in APVA. In NPVA cases the thermal forcing is essential to the cyclogenesis, while in the APVA the cyclonic vorticity induced by PVA at upper levels propagating to low levels is more important. The NPVA cases present more baroclinic characteristics which the upper and mid-level troughs accompanied by the jet stream favoring the surface cyclone development, whereas in the APVA the surface cyclone center remains almost vertically aligned with these troughs. For APVA cases, the centers of cyclonic vorticity at 500 hPa detach from westerly flow in all seasons however in summer this is also seen in NPVA.

Nesta dissertação, investigarei de que forma as regras do processo orçamentário do Brasil, Chile e Argentina explicam os seus respectivos desempenhos fiscais nos anos 1990 e 2000. Para isto, construo um modelo teórico com raízes no problema do estoque comum de recursos e trabalho com a hipótese de que quanto mais centralizada for a segunda etapa do ciclo orçamentário (etapa de tramitação da proposta do Executivo no Congresso) e a terceira (etapa de execução do orçamento), mais equilibrado tende a ser o desempenho fiscal. A forma ideal de centralização é restringir o poder do Legislativo de decidir sobre política fiscal e tornar a lei impositiva durante a execução, permitindo ao Executivo apenas ajustar os gastos de acordo com a arrecadação tributária. Somente o Chile centralizou o seu processo orçamentário da forma ideal, enquanto a maneira com que a Argentina e o Brasil o fizeram lança dúvidas sobre a manutenção de uma política fiscal responsável no futuro. Este trabalho inova no sentido de investigar detalhes da estrutura micro-institucional de cada um dos países e mostrar que esses detalhes ajudam a entender com mais clareza o sentido do impacto das micro-instituições na performance fiscal de um país. / In this dissertation I will investigate how the rules of the budgetary process in Brazil, Chile and Argentina explain their respective fiscal performance in the 1990\'s and 2000\'s. In order to do that, I will create a theoretical model based on the common pool of resources problem and work with the hypothesis that the more centralized the budgetary cycle\'s second stage (stage in which the Executive proposal is discussed by the Congress) and third stage (budget execution), the more balanced tend to be the fiscal performance. The most effective way of centralization is to constrain the Legislative power to make decisions on fiscal policy and to impose the law during the execution, allowing the Executive only to adjust the expenses according to tax collection. Only Chile has centralized its budgetary process in the most effective way, whereas the way how Argentina and Brazil have done it casts doubts on the maintenance of a responsible fiscal policy in the future. This work innovates in the sense that it investigates details of the micro-institutional framework of each country and shows that these details help us to understand the impact of micro-institutions on a country\'s fiscal performance.

Nos últimos anos, pode-se visualizar o aumento das produções e das publicações sobre o tema da infância pela ótica dos cientistas sociais, que a têm investigado sob nova perspectiva, assim como discutido e verificado outras possibilidades metodológicas de se realizar pesquisas com e sobre crianças, num movimento de busca de compreensão do seu papel e do da infância no mundo contemporâneo. Ao considerar que o campo da sociologia da infância tem produção internacional e que pesquisadores de diferentes países têm apresentado suas pesquisas em congressos da área e publicado seus trabalhos em livros ou periódicos, verificou-se que há pouca informação sobre estudos da infância na América do Sul. Esta pesquisa propôs-se a investigar o desenvolvimento do campo em ao menos dois países deste continente, a fim de compreender o que se tem pesquisado e produzido na perspectiva da sociologia da infância. A investigação mapeou, considerando o período de 2010 a 2013, as produções de autores sul-americanos hispano-falantes, por meio da consulta a diferentes bases de dados, da realização de visitas aos países escolhidos para melhor conhecimento da produção, e de entrevistas com os pesquisadores. Para a compreensão da configuração do campo na América do Sul, recorreu-se ao conceito de campo científico em Bourdieu, sendo que, com as contribuições da obra desse autor, juntamente com a realização da análise de conteúdo, foram identificados os temas consagrados nas publicações, as abordagens teóricas, os caminhos metodológicos, as áreas predominantes nos estudos, e os elementos que estruturam o campo na Argentina e no Chile, países investigados. Considera-se que o campo da sociologia da infância e o campo interdisciplinar dos estudos sociais da infância convivem nesses países, como resultado das diferentes formações dos pesquisadores do campo e dos variados contextos de vida das crianças. Constata-se que, num primeiro momento, as produções europeia e norte-americana tiveram grande influência na realização de investigações científicas nos países investigados, mas conclui-se que os movimentos próprios do campo podem estruturar outros caminhos para as produções e teorizações da infância no hemisfério sul. / In recent years, we have seen an increase in the productions and publications on the theme of childhood from the perspective of the social scientists who have investigated childhood by discussing it applying other methodologies when conducting research with and about children. It has led to a new movement which aims at understanding the role of children and childhood in the contemporary world. Considering the worldwide width of sociology of childhood, little has been shown in conferences and literature about childhood studies in South America. Having noticed this lacking, the present research headed to investigate the development of the field in at least two South American countries in order to understand what has been researched and produced from the sociology of childhood perspective. The study mapped the production of South American and Spanish-speaking authors from 2010 to 2013, by consulting different databases, visiting the selected countries and interviewing researchers so to have a better understanding of the productions. In order to comprehend the field in South America configuration, we adopted the concept of the scientific field of Bourdieu, and with his theoretical background and the content analysis, we were able to identify the themes consecrated, the theoretical approaches, the methodological procedures, the predominant areas, and also the elements that structure the field in Argentina and Chile, the investigated countries. We noticed that the field of the sociology of childhood and the interdisciplinary field of social studies of childhood coexist in these countries, which is due to the different academic background the researchers of the field have and the varied contexts of children\'s life. Initially, European and North American productions had a great influence on the conduct of scientific research in the countries investigated, but the movements of the field can structure other pathways for the productions and theorizations of children in the Southern Hemisphere.

A presente tese se propõe a responder a seguinte questão: É correto afirmar que o regionalismo desenvolvimentista sul-americano, implantado ao longo do século XX, e o novo regionalismo desenvolvimentista, implantado ao longo da primeira década do século XXI, são compatíveis com as regras do sistema multilateral de comércio? Em outras palavras, as organizações de integração regional da América do Sul têm balizado as suas políticas desenvolvimentistas no policy space decorrente das prerrogativas jurídicas para o desenvolvimento do sistema multilateral de comércio? Para tratar o refrido tema, parte-se da premissa que os países da América do Sul historicamente sempre fizeram uso das prerrogativas jurídicas para o desenvolvimento, desde que tais surgiram no sistema multilateral de comércio, e possibilitaram a implantação de políticas no plano nacional e regional. Ao longo da tese, é analisada, desde uma perspectiva jurídica, a compatibilidade com as regras do sistema multilateral de comércio dos principais aspectos desenvolvimentistas das organizações de integração regional criadas na América do Sul, desde a ALALC, em 1960, até a UNASUL, em 2008. Concluiu-se que tanto o velho quanto o novo regionalismo desenvolvimentista da América do Sul foram levados adiante em concordância com o direito internacional do comércio, seja ao longo do período GATT, seja ao longo do período OMC. Mesmo com a redução de policy space decorrente da entrada em vigor dos acordos da OMC, a América do Sul vislumbrou manter um relativamente alto nível de espaço político (policy space) para a criação de políticas públicas de desenvolvimento. Atualmente, percebe-se uma tendência das organizações de integração regional da América do Sul, especialmente da UNASUL e do MERCOSUL, de levar adiante políticas públicas em torno de temas não-regulados pela OMC, o que caracterizaria uma estratégia OMC-extra. O novo regionalismo desenvolvimentista sul-americano está finalmente se constituindo para além do policy space do sistema multilateral de comércio, o que, por não configurar, a priori, uma incompatibilidade dos processos de integração com as regras da OMC, contribui para fortalecer o primado do direito internacional na América do Sul. / This thesis aims to answer the following question: Can it be said that the South American developmental regionalism, carried out throughout the twentieth century, and the new developmental regionalism, implemented during the first decade of this century, are compatible with the rules of multilateral trading system? In other words, have the regional integration organizations in South America based their developmental policies in the policy space resulting from the developmental legal prerogatives of the multilateral trading system? To treat such theme, we start from the premise that the countries of South America have historically made use of legal rights for development, since these arose in the multilateral trading system, and enabled the implementation of policies at the national and regional levels. From a legal perspective, the thesis analyses the compatibility of the main developmental aspects of regional integration organizations created in South America since the LAFTA in 1960 to UNASUR, in 2008 with the rules of the multilateral trading system. It was concluded that both the old and the new developmental regionalism in South America were brought forward in accordance with international trade law, either through the GATT period, either during the WTO period. Even with the reduction of policy space resulting from the entry into force of the WTO agreements, South America managed to maintain a relatively high level of policy space for the creation of developmental public policies. Currently, there is a perceived trend of regional integration organizations in South America, especially the MERCOSUR and UNASUR, to carry out public policies on topics unregulated by the WTO, which would characterize a strategy WTO-extra. The new South American developmental regionalism is finally going beyond the policy space of the multilateral trading system, which, by not setting a priori incompatibility of the integration processes with WTO rules, contributes to strengthen the rule of international law in South America.
