The process of expansion of the urban space of the Maceió city, characterized for the creation of valued regions more beyond the limits of the Central Area, stimulated, over all, for the technological development through vulgarization the automobile that made possible new displacements and for the real estate activity that the objective had to create new vectors of occupation, coincides with the period of abandonment of the Center as main place of housing and localization of the ranks of work, the commerce and the services. Following this process of occupation new areas city dwellers, it was had action of the public power in disencumbering the transit of the central region, in the decade of 1980, virtue of the little capacity to absorb the demanded demand of vehicles. This action was reflected in the creation of new elements - Zones and Corridors of Multiple Activities - in which the tertiary activity could be installed. Being, initially, responsible in approaching the tertiary activities of the residences, creating new centralities, the Corridors of Multiple Activities, had had its concept and function transformed, passing to be defined from the ticket of the public transport, without the function and the capacity of the ways were considered where they had been installed. The result of this process discloses to a significant alteration in the landscape and the spaces of circulation and conviviality reflecting an overlapping of functions which start to compromise the development of each one in concurrence. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O processo de expansão do tecido urbano da cidade de Maceió, caracterizado pela criação de regiões mais valorizadas além dos limites da Área Central, incentivado, sobretudo, pelo desenvolvimento tecnológico através vulgarização do automóvel que possibilitou novos deslocamentos e pela atividade imobiliária que tinha o objetivo de criar novos vetores de ocupação, coincide com o período de abandono do Centro como principal local de moradia e de localização dos postos de trabalho, do comércio e dos serviços. Acompanhando este processo de ocupação de novas áreas citadinas, teve-se a ação do poder público em desafogar o trânsito da região central, na década de 1980, em virtude da pouca capacidade de absorver a demanda exigida de veículos. Esta ação estava refletida na criação de novos elementos Zonas e Corredores de Atividades Múltiplas nos quais a atividade terciária pudesse se instalar. Sendo, inicialmente, responsáveis em aproximar as atividades terciárias das residências, criando novas centralidades, os Corredores de Atividades Múltiplas, tiveram seu conceito e função transformados, passando a ser definidos a partir da passagem do transporte público, sem que fossem consideradas a função e a capacidade das vias em que foram instalados. O resultado deste processo revela uma alteração significativa na paisagem e nos espaços de circulação e convivência, refletindo uma sobreposição de funções as quais passam a comprometer o desenvolvimento de cada uma em simultaneidade.

Cette étude s'organise autour d'une réflexion sur l'occupation humaine de la Tassili du Fadnoun (sud-est algérien) à travers l'analyse architecturale des tumulus à couloir et enclos et de leurs contextes géographique et funéraire. La position géographique de ce grand massif, à proximité de Tanget, de la Tassedjebest, de la Tamelghiq et des autres massifs situés au sud-est, lui confère un rôle de carrefour où s'échangeaient les productions culturelles parmi lesquelles figurent l'art rupestre et l'architecture funéraire. Depuis la publication de Jean Pierre Savary qui date du début des années soixante, l'étude des monuments funéraires du Fadnoun n'a pas connu d'évolution importante. L'objectif majeur de notre recherche est de réexaminer les données anciennes concernant les tumulus à couloir et enclos et de donner une impulsion à de nouvelles recherches introduisant les systèmes d'information géographique (SIG) et l'imagerie satellitaire à une échelle et un contexte régional plus large. Le complément d’étude que nous apportons dans le cadre de cette thèse s'inscrit clairement dans la continuité des travaux antérieurs. Ces premiers résultats obtenus sont un point de départ pour des recherches ultérieures dans la Tassili du Fadnoun, restée longtemps marginalisée en raison des difficultés d'accès. Il ressort de cette étude, malgré une distribution géographique très étendue à l’échelle des massifs du Sahara centro-méridional que les monuments de type à couloir et enclos présentent plusieurs caractéristiques communes notamment en matière d'architecture, de mode d'inhumation et de datation. / This study focuses the human occupation of the Tassili of Fadnoun (south-east Algeria) through the architectural analysis of the corridor and enclosures tumuli and their geographical and funerary contexts. The geographical position of this great massif, near Tanget, Tassedjebest, Tamelghiq and the other massifs situated in the south-east, gives it a role of crossroads where cultural productions including rock art and funerary architecture were exchanged. Since the publication of Jean Pierre Savary, which dates from the early sixties, the study of funerary monuments of the Fadnoun has not undergone significant evolution. The main objective of our research is to re-examine the old data concerning corridor and enclosure tumuli and to give impetus to new research introducing Geographic Information Systems (GIS) and satellite imagery to a wider scale and regional context. The complementary study carried out in this thesis is clearly in line with the previous work. These initial results are a starting point for further research in the Tassili of Fadnoun, which has long been marginalized because of difficulties of access. This study shows that corridor and enclosure type monuments have several common characteristics, notably in architecture, burial mode and dating, in spite of a very wide geographical distribution all over of the central Saharan massifs.

Hymenoptera are a key group for setting priorities for conservation, since they represent a high proportion of diversity of insects , being easily sampled. The aim of this study was to characterize the fauna of Hymenoptera parasitoids associated with Lepidoptera larvae in agrosilvopastoral and silviagricultural systems and in reforestation area (ecological corridor) of the Fazenda Canchim (Embrapa Pecuária Sudeste), São Carlos, SP, Brazil. Lepidoptera larvae collected with beating tray were kept in the laboratory until the emergence of adults or of their parasitoids. From hosts collected in the reforestation emerged 69 parasitoids, thus identified: Chalcididae, Chalcidinae (Conura); Ichneumonidae, Pimplinae (Neotheronia) and Campopleginae (Charops and Microcharops); and Braconidae, Microgastrinae (Apanteles, Diolcogaster, Distatrix, Glyptapanteles and Protapanteles). From those collected in the agrosilvopastoral and silviagriculture systems 267 hymenopteran parasitoids emerged thus identified: Braconidae, Agathidinae (Alabagrus), Braconinae (Bracon), Microgastrinae (Cotesia, Diolcogaster, Glyptapanteles, Pholetesor and Protapanteles), and Orgilinae (Orgilus); Ichneumonidae, Campopleginae (Casinaria, Charops and Microcharops); Chalcididae, Chalcidinae (Brachymeria and Conura); and Eulophidae, Entedoninae (Horismenus) and Eulophinae (Elachertus and Euplectrus). The environments studied are home to wide variety of genera of Hymenoptera parasitoids through greater availability of food resources for them and for their hosts (immatures and adults). Reforestation practices and use of mixed systems environment should be encouraged. / Estudos da flora e fauna silvestres são importantes por contribuirem para a compreensão dos processos ecológicos que ocorrem em resposta às estratégias de manejo utilizadas. Os Hymenoptera são um grupo-chave para o estabelecimento de prioridades em conservação do ambiente, pois representam alta proporção da diversidade de insetos, sendo facilmente amostrados. O objetivo deste trabalho foi caracterizar a fauna de Hymenoptera parasitoides associada às larvas de Lepidoptera em área de reflorestamento (corredor ecológico) e nos sistemas agrossilvipastoril e silviagrícola da Fazenda Canchim (Embrapa Pecuária Sudeste), São Carlos, SP, Brasil. Larvas de Lepidoptera coletadas com guarda-chuva entomológico foram mantidas em laboratório até a emergência dos seus adultos ou de seus parasitoides. Das larvas coletadas na área de reflorestamento emergiram 69 Hymenoptera parasitoides, identificados como: Chalcididae, Chalcidinae (Conura); Ichneumonidae, Pimplinae (Neotheronia) e Campopleginae (Charops e Microcharops); e Braconidae, Microgastrinae (Apanteles, Diolcogaster, Distatrix, Glyptapanteles e Protapanteles).

Os ambientes estudados abrigam grande diversidade de gêneros de Hymenoptera parasitoides, provavelmente, devido à maior disponibilidade de recursos alimentares para os mesmos e para os seus hospedeiros (formas imaturas e adultos). Práticas de reflorestamento e a implantação de sistemas mistos de utilização do ambiente devem ser estimulados.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The aim of this work is to evaluate the reliability of the urban public transport using as a study case the bus structural corridor in the João Naves de Ávila Avenue, one of the main avenues in Uberlândia, MG, Brazil. Two softwares, Simulation and Assignment of Traffic in Urban Road Networks SATURN and Dynamic Route Assignment Combining User Learning and Microsimulation DRACULA, both developed by the University of Leeds UK, were used to simulate and conclude about the influence of the deployment of the corridor on the bus route. Here it is presented an analysis on the reliability for the public transport along the avenue, where a bus-only lane and thirteen boarding and alighting stations were built, through indicators such as travel time, punctuality and regularity, among others. Through the simulation of various scenarios, this work also presents an analysis on how reliability indicators were affected by the proposed changes. Finally, a comparison between the travel time before and after the construction of the bus corridor allowed a conclusion to be reached on the actual benefits brought on by the deployment of a structural bus corridor in medium sized cities. / Este trabalho tem como objetivo avaliar a confiabilidade do transporte coletivo urbano por ônibus tendo como base o corredor estrutural de ônibus da Avenida João Naves de Ávila, uma das principais vias da cidade de Uberlândia, MG.

Os programas, ambos desenvolvidos pela Universidade de Leeds, na Inglaterra, foram usados na execução das simulações necessárias para concluir quanto ao efeito que a implantação do corredor de ônibus acarretou sobre a linha de ônibus que percorre a avenida. É apresentada uma análise sobre a confiabilidade do transporte coletivo urbano na avenida, onde foi implantada uma faixa exclusiva para ônibus e treze estações de embarque e desembarque, por meio de indicadores como tempo de viagem, regularidade e pontualidade, entre outros. Além do cenário básico, foram propostos cenários variados a fim de verificar como os indicadores de confiabilidade seriam afetados. Por fim, esse trabalho traz a comparação entre os tempos de viagem antes e após a implantação do corredor e visa concluir sobre os benefícios reais da implantação de um corredor de ônibus em cidades médias. / Mestre em Engenharia Civil

Effects of functioning transportation infrastructure are receiving more and more environmental and social concern nowadays. Nevertheless, preliminary corridor plans are usually developed on the basis of technical and economic criteria exclusively. By the time of environmental impact assessment (EIA), which succeeds, relocation is practically impossible and only preventative measures can be applied. This paper proposes a GIS-based method of delimiting motorway corridor and integrating social, environmental and economic factors into the early stages of planning. Multiple criteria decision making (MCDM) techniques are used to assess all possible alternatives. GIS-held weighted shortest path algorithm enables to locate the corridor. The evaluation criteria are exemplary. They include nature conservation, buildings, forests and agricultural resources, and soils. Resulting evaluation surface is divided into a grid of cells, which are assigned suitability scores derived from all evaluation criteria. Subsequently, a set of adjacent cells connecting two pre-specified points is traced by the least-cost path algorithm. The best alternative has a lowest total value of suitability scores. As a result, the proposed motorway corridor is routed from origin to destination. It is afterwards compared with an alternative derived by traditional planning procedures. Concluding remarks are that the location criteria need to be adjusted to meet construction requirements as well as analysis process to be automated. Nevertheless, the geographic information system and the embedded shortest path algorithm proved to be well suited for preliminary corridor location analysis. Future research directions are sketched.

Coimbra-Filho’s titi monkey, Callicebus coimbrai, is an endemic primate of the Atlantic Forest of the Brazilian Northeast, found only in Sergipe and northern Bahia. The species has been the focus of research and conservation efforts over the past twelve years, which has integrated the region’s scientists and institutions. The study presented here provides continuity, with three distinct, but complementary approaches. The first approach was an ecological study in the Mata do Junco Wildlife Refuge, in the municipality of Capela, in the Brazilian state of Sergipe. The results of this study highlighted the ecological resilience of the species in the face of habitat fragmentation. The titi is relatively inactive, spending most of the day at rest, and is predominantly frugivorous, although the proportion of time spent foraging was higher than in most previous studies of the same group, which may be related to variation in observational procedures. While some significant variation was found in the composition of the diet, the behavior of the members of the study group changed very little between the different periods of the year, or even among years, in comparison with previous years. Two aspects of the behavior of the animals were highlighted, however. One was the breakdown in the dispersal mechanism from the natal group, which apparently resulted in an endogamous mating between the resident reproductive male and its mature daughter. This is the second case of endogamy recorded in C. coimbrai, which may result from the inflexible social organization of the species in the context of habitat fragmentation, and represents a potentially serious problem for the long-term conservation of the species. The second new behavior was the predation of termites (Nasutitermes sp.), which appears to reflect the behavioral flexibility of C. combrai, and may represent a positive feature of the capacity of the species to cope with habitat fragmentation. In the second theme, the ecological concept of keystone species/resources was reviewed through a systematic literature search, which aimed to evaluate the potential practical applications of the concept for the conservation of C. combrai. This review revealed an extensive literature, which has grown almost exponentially in recent years, although the concept has been applied relatively rarely in primate studies. Together with the data accumulated on the ecology of the species, the discussion of the concept indicated that the extension of forest is a keystone resource for the conservation of C. coimbrai. This conclusion supports the third approach, which was an evaluation of the potential for the implementation of a network of ecological corridors in the study area. The analysis identified three priorities for the formation of corridors, one in the buffer zone of the RVS Mata do Junco, the second to the south of the area, and the third linking the refuge to the AIE Mata do Cipó. The thesis provides valuable insights into the long-term conservation of the species, but emphasizes the need for integrated efforts in research and practical action by environmental organs, research institutions, and the local population. / O guigó-de-coimbra, Callicebus coimbrai, é uma espécie de primata endêmica da MataAtlântica do nordeste brasileiro, encontrada somente em Sergipe e no extremo nordeste da Bahia. A espécie tem sido o alvo de esforços de pesquisa e conservação ao longo dos últimos doze anos, integrando pesquisadores e instituições da região. A pesquisa apresentada nesta tese dá continuidade a estes esforços através de três abordagens distintas, mas complementares. A primeira abordagem foi o estudo ecológico no Refúgio de Vida Silvestre Mata do Junco, no município sergipano de Capela, cujos resultados refletem principalmente a resiliência ecológica da espécie frente à fragmentação de habitats. O guigó é uma espécie pouco ativa, que passa a maior parte de seu dia descansando, e predominantemente frugívora, embora a proporção de tempo gasto em forrageio foi maior que na maioria dos estudos anteriores do mesmo grupo, podendo ser relacionado a variação nos procedimentos observacionais. Apesar de alguma variação sazonal significativa na composição da dieta, o comportamento dos membros do grupo de estudo mudou muito pouco entre diferentes períodos do ano, ou mesmo entre anos, na comparação com estudos anteriores. Dois aspectos do comportamento dos animais se destacaram, entretanto. Um foi uma falha no mecanismo de dispersão do grupo natal, que resultou num acasalamento aparentemente endogâmico entre o macho reprodutor residente e sua filha, amadurecida. Este é o segundo caso de endogamia registrado em C. coimbrai, que parece resultar da inflexibilidade da organização social da espécie, frente à fragmentação de habitat, e representa um problema potencialmente grave para a conservação da espécie em longo prazo. Outra novidade foi a predação de cupins (Nasutitermes sp.), que parece refletir a flexibilidade do comportamento de C. combrai e pode representar um aspecto positivo de sua capacidade de lidar com a fragmentação de habitat. Na segunda abordagem, foi revisada o conceito ecológico de espécie/recurso chave, através de uma revisão sistemática da literatura, visando avaliar o potencial para aplicações práticas na conservação de C. combrai. A revisão revelou uma literatura extensa, com crescimento quase exponencial em anos recentes, embora o conceito tem sido aplicado relativamente raramente em estudos de primatas. Junto aos dados acumulados sobre a ecologia da espécie, a discussão do conceito apontou para a extensão de floresta como o recurso chave para a conservação de C. coimbrai. Esta conclusão apoiou a terceira abordagem, que foi uma avaliação do potencial para a implementação de uma rede de corredores ecológicos na área de estudo. A análise identificou três prioridades para a formação de corredores, uma no entorno do RVS Mata do Junco, a segunda no sul da área, e a terceira ligando o refúgio com a AIE Mata do Cipó. A tese oferece valiosos insights para a conservação da espécie em longo prazo, mas frisa a necessidade de esforços integrados de pesquisa e ação prática por parte de órgãos ambientais, instituições de pesquisa e a população local. / São Cristóvão, SE

A área do Jardim Botânico da Universidade Federal de Juiz de Fora (JB-UFJF) está inserida na região da Zona da Mata de Minas Gerais, município de Juiz de Fora, que sofreu os impactos da cultura cafeeira e da criação de gado. A área encontra-se em regeneração há cerca de 70 anos, estando próxima a outros fragmentos florestais de grande relevância ambiental, integrando o Corredor Ecológico da Serra do Mar. O objetivo deste estudo foi determinar a composição florística do JB-UFJF, bem como sua similaridade com fragmentos florestais situados no Sudeste brasileiro, avaliando a importância da área de estudo para a conservação da flora do município e suas relações florísticas com outros fragmentos florestais. As coletas foram realizadas em 2011 e 2012 e o material coletado está depositado no Herbário CESJ da UFJF. A similaridade foi calculada pelo índice de Jaccard, com um dendograma baseado na média de grupo (UPGMA) entre o JB-UFJF e outros 12 levantamentos florísticos de MG, RJ e SP. Foram registradas 432 espécies distribuídas em 269 gêneros e 96 famílias. As famílias mais ricas em espécies foram Fabaceae (35 spp), Melastomataceae (27 spp), Rubiaceae (27 spp), Solanaceae (21 spp), e Asteraceae (20 spp). Os gêneros mais ricos foram Miconia (15 spp), Piper (12 spp), Psychotria (9 spp) e Solanum (8 spp). Seis espécies encontradas no JB-UFJF estão categorizadas como ameaçadas de extinção na Lista Vermelha de Minas Gerais (2000). Cyclopogon variegatus teve seu primeiro registro para Minas Gerais. A riqueza específica do hábito herbáceo foi a segunda mais alta (21,29%), seguindo o arbóreo (50,46%), o que mostra a importância do componente herbáceo em levantamentos florísticos. A similaridade do JB-UFJF com outros fragmentos de Floresta Estacional Semidecidual de Minas Gerais e o padrão observado no dendograma incluem a área na tipologia Floresta Estacional Semidecidual, como área transicional do Corredor Ecológico da Serra do Mar. / The Atlantic Forest is one of the richest ecosystems of the world and, although well represented among biomes of the state of Minas Gerais is still lacking of floristics studies that document the richness of its flora. The area of the Botanical Garden of the Federal University of Juiz de Fora (JB-UFJF) is inserted in the Zona da Mata region, in Minas Gerais, city of Juiz de Fora, which suffered the impact of coffee cultivation and cattle. The area is undergoing a process of regeneration for about 70 years, being close to other forest fragments that have great environmental relevance and integrating the ecological corridor of Serra do Mar. The aim of this study was to determine the floristic composition of the JB-UFJF as well as its similarity to forest fragments located in southeastern of Brazil, in order to evaluate the importance of the JB-UFJF to into the conservation of the flora of the city and its floristic links with other forest fragments. The collections were carried out in 2011 and 2012 and the collected material is deposited in the Herbarium CESJ of UFJF. The similarity was calculated by Jaccard index with a dendrogram based on the Unweighted pair group method with arithmetic mean (UPGMA) between the JB-UFJF and other 12 floristic surveys of MG, RJ and SP. 432 species were recorded, distributed in 269 genera and 96 families. The families with the biggest richness of species were Fabaceae (35 spp), Melastomataceae (27 spp), Rubiaceae (27 spp), Solanaceae (21 spp), and Asteraceae (20 spp). The richest genera were Miconia (15 spp), Piper (12 spp), Psychotria (9 spp) and Solanum (8 spp). Six species found in the area are endangered according to the Red List of Minas Gerais (2000). Cyclopogon variegatus had its first record for Minas Gerais. The richness of the herbaceous species was the second highest (21,29%), following the arboreal (50,46%), which shows the importance of the herbaceous stratum in floristic surveys. The similarity of the JB-UFJF with other fragments of semi-deciduous forest of Minas Gerais and the pattern observed in the dendrogram include the area in the Semideciduous Forest typology, as a transitional area of the Serra do Mar Ecological Corridor.

Climate change threatens to disrupt biological systems around the globe, sparking debate over natural capacity for adaptation in a fragmented landscape. Marine turtles are evolutionarily ancient and have survived millions of years of prehistoric climate change, but are threatened by the rapidity of modern warming and a history of severe overexploitation that has left most populations depleted. This thesis explores a nesting aggregation of the green turtle (Chelonia mydas) in northern Cyprus, where a longitudinal programme of both intensive and extensive monitoring enables insight into individual and population level parameters and processes. Nesting on the two coastlines covered by this project is in the early stages of recovery, possibly in response to exhaustive nest protection efforts over the last twenty years. Saturation tagging at one key site allows us to confirm that recruitment of new breeders is an important driver of this trend, and that average clutch frequency has remained stable around three nests per female per year, validating nest-count derived abundance estimates at a regional scale. Concern has been raised, however, regarding recent changes in fishing practices which are impacting the local juvenile neritic phase, which may have a lagged effect on the recovery of this nesting population. A collaborative tracking effort including all other countries with major nesting in the Mediterranean allows us to identify major foraging grounds for this species, with two hotspots accounting for >50% of tracked individuals, as well as coastal and pelagic seasonal corridors of high use. Bycatch levels and mortality rates for turtles in these key areas are largely unknown and should be prioritised for investigation. Hatchling sex ratios from the main study beach are extremely female-biased (estimated 97% female for the twenty year period 1993-2012). A 1oC rise in average incubation temperatures threatens near complete hatchling feminisation on this beach, whilst a 2oC rise could reduce hatch success to less than 50%. Thermal effects on hatchling morphometrics are evident, with a 1oC rise in temperature reducing average length, width and weight by 1%, 2% and 3% respectively. More favourable incubation conditions were found early in the season, in deeper nests laid by larger females, and on beaches of lighter sand. In contrast, adult sex ratios at the main site are male-biased, posing questions regarding sex-specific survival rates and optimal hatchling sex ratios. A phenological shift towards earlier nesting is demonstrated for the first time in this species, and could potentially ameliorate warming effects. Carry-over climate forcing effects from the foraging ground influence the breeding frequency of individuals, driving population level responses in annual magnitude of nesting. This work emphasises the utility and necessity of long-term individual-based monitoring programmes in elucidating population trends and climate responses in iteroparous species with non-annual breeding.

Notre recherche interroge la portée de la nouvelle politique environnementale de la capitale chinoise, dont la mise en oeuvre a été précipitée dans le cadre de l'accueil des Jeux Olympiques.Si la trame urbaine de Pékin était encore il y a peu l'un des derniers héritages des préceptes traditionnels d'aménagement de l'espace chinois entre "montagne et eau" et se référant au “souffle - qi”, qui anime toute chose et tout être dans la cosmogonie chinoise et qui est à la base de l'implantation de la ville sur son site, les politiques urbaines menées au cours du XXe siècle ont détruit en grande partie cet héritage.La prise de conscience environnementale amorcée dans les années 90 a généré une nouvelle approche au territoire qui s'est accélérée en 2001 dans l'optique de l'accueil des green Olympic Games en 2008. La reforestation de la capitale chinoise a alors été considérée à toutes les échelles, de celle du pays à celle de la rue.A l'échelle de son territoire périurbain, Pékin s'est dotée de deux ceintures vertes. Pour autant, le gouvernement municipal a choisi la voie de l'originalité en planifiant des "ceintures vertes habitées", à 50%pour la première et à 30% pour la seconde. A l'échelle de sa zone urbaine, la municipalité a mis en place de nouvelles promenades paysagères qui s'étirent le long des routes et des canaux et qui font apparaitre une nouvelle typologie d'espaces publics qui trouve son origine dans la réhabilitation de l'axe historique nord-sud et qui a permis outre la réhabilitation de l'histoire ancienne, celle de la réhabilitation du paysage ancien.Des ceintures vertes aux coulées vertes, la qualité de vie est sans nul doute améliorée à Pékin. Ce souffle vert est-il pour autant porteur d'une nouvelle identité urbaine? Attendons encore pour voir. Pékin 2050. Alors ce souffle vert? / Our research examines the scope of the new environmental policy for the Chinese capital, whoseimplementation was precipitated by the hosting of the Olympic Games.If the Beijing urban fabric was one of the last vestiges of the traditional Chinese precepts of spatialplanning between "mountain and water" and referring to "breath – qi" that animates all things and allbeings in the Chinese cosmogony, and that is the basis of the establishment of the city on its site, theurban policies implemented during the twentieth century have destroyed much of this heritage. Theenvironmental awareness that emerged in the 90s has generated a new approach to the territory, whichwas expedited in 2001 in view of hosting the green Olympic Games in 2008. The reforestation of theChinese capital was then considered at all scales, from that of the country to that of the street.At the scale of its periurban area, Beijing has built two green belts. However, the municipal governmenthas chosen an original approach by planning two "inhabited green belts ", 50% for the first and 30% for thesecond. At the scale of its urban area, the municipality set up new scenic walks along roads and canals,revealing a new typology of public spaces that finds its origin in the rehabilitation project of the historicnorth-south axis and that has also allowed the rehabilitation of ancient history and of the ancientlandscape.From green belts to green corridors, the quality of life is undoubtedly better in Beijing. Has, however, thisnew breath of green created a new urban identity? Let's wait and see. Beijing 2050. So, what about this new breath of green?
