Introduction -- The peaceful path to real reform -- The garden city movement -- An international phenomenon -- Australia: setting the scene -- Importing the garden city -- Overview of theory and practice -- An environmental ideal -- Garden city principles -- Garden towns -- Garden villages -- Garden suburbs -- The metropolitan scale -- Conclusion.
The garden city tradition in estate and metropolitan design derived its name from the garden cities advocated by Ebenezer Howard in To-Morrow (1898). A major force in the history of British planning, its influence was felt around the world. This thesis is the first overview of Australian theory and practice, focusing on the period between 1910 and 1930. Five basic tasks are attempted: an outline of the original garden city idea; an examination of the general ideology and organization of the garden city movement; clarification of the international context; specification of the general character and distinctiveness of garden city advocacy in Australia; and a systematic record of actual projects. -- The discussion indicates that the nature of the Australian response reflected the interaction of imported ideas with local circumstances. As in other countries, Howard's 'peaceful path' to 'a better a brighter civilization' was not fully followed. Instead, the garden city assumed three main guises. First, it functioned as an inspirational environmental ideal. Second, it brought together concrete principles for improved lay out that were advocated for and implemented in three different settings: special purpose 'garden towns'; 'tied' housing estates for industrial employees; and residential suburbs and subdivisions. These 'garden suburbs' dominated the local scene but, as with the other developments, translation of the ideal into reality was imperfect, being deleteriously affected by financial, political, and administrative factors in particular. Third, and at a larger scale, the garden city helped to introduce certain tentative ideas regarding the desirable size, shape and structure of the metropolis. -- The approach adopted is basically empirical, with the most important source material being the contemporary Australian planning literature. The structure is best described as 'stratified chronology'. The analytical framework combines three main approaches to planning historiography: the societal (setting planning events and developments in their broadest economic, political, cultural, and institutional context), the biographical (emphasizing the important role of individuals in the importation, diffusion and implementation of garden city thought), and the morphological (a spatial emphasis involving an inventory of landscape impacts). The major theme permeating the thesis is that of the 'diluted legacy': the drift in the garden city tradition away from Howard's holistic, radical manifesto through liberal environmental reforms to actual schemes which compromised or even totally contradicted the original idea in physical, economic and social terms. The extension and conceptualization of this idea provides one of several important areas for future research highlighted by the thesis.

Resumo: O botânico brasileiro Frederico Carlos Hoehne (1882-1959) iniciou sua carreira como jardineiro-chefe do Museu Nacional do Rio de Janeiro em 1907. No ano de 1917, ao ser convidado para fundar o Horto Oswaldo Cruz no Instituto Butantã, se muda para São Paulo, onde solidifica sua carreira fundando e dirigindo hortos e instituições de pesquisa até o ano de 1952, quando se aposenta. Hoehne é reconhecido como um grande defensor da natureza e também por sua paixão por orquídeas. Contudo, este trabalho tem como objetivo investigar um aspecto ainda pouco explorado na vasta produção do autor, referente ao seu estudo para a indicação de espécies nativas para a arborização urbana. Publicado em 1944, o livro "Arborização Urbana" foi um dos primeiros a tratar sobre este tema, se aproximando dos manuais de arborização atuais. A investigação sobre quais eram essas espécies, sua relação com as espécies do manual de arborização mais recente da cidade de São Paulo (2015) e a origem das referências que subsidiaram Hoehne a indicar tais espécies foram o fio condutor da pesquisa apoiada nos Relatórios escritos pelo autor nas instituições em que trabalhou. O objetivo específico é verificar a atualidade e a contribuição do botânico para a preservação das árvores nativas e sua difusão no meio urbano.
Abstract: The brazilian botanist Frederico Carlos Hoehne (1882-1959) began his career as head gardener of the National Museum of Rio de Janeiro in 1907. In 1917, when invited to found Horto Oswaldo Cruz in the Butantã Institute, he moves to São Paulo, where he solidifies his career by founding and directing gardens and research institutions until 1952, when he retires. Hoehne is recognized as a great advocate of nature and also for his passion for orchids. However, this work aims to investigate an aspect not much explored in the vast production of the author, about his study for the indication of native species for urban afforestation. Published in 1944, the book "Arborização Urbana" was one of the first to address this issue, approaching the current urban afforestation manuals. The research on these species, their relation to the species of the most recent urban afforestation manual of the city of São Paulo (2015) and the origin of the references that subsidized Hoehne to indicate such species was the guiding line of the research, which relied on Reports written by the author in the institutions that worked. The specific objective is to verify the actuality and the contribution of the botanist for the preservation of the native trees and their diffusion in the urban environment.

Testo completoThis ethnography is based on fieldwork in two very different cities, Hong Kong and Sydney. It traces the movements of subjects from Hong Kong through the analysis of differing modes of inhabiting urban space. The texture of lived spaces provides an analytic focus for examining a highly mobile migrant group. This ethnography explores the mesh of objective structures and migrant subjectivities in a mobile field of migrant ‘place’. A basic assumption of this study is that people from Hong Kong have acquired a common array of dispositions attuned to living in a specific environment. Hong Kong’s dense and challenging urban space embodies aspects of the singular historical ‘production of space’ underpinning a colonial entrepôt that has expanded into a major global economic node. The conditions of lived space are examined through an historical analysis of urban space in Hong Kong and an ethnographic analysis of spatial practices and dispositions. The sprawling spaces of suburban Sydney clearly differ sharply from that of Hong Kong. Interview accounts of settling in Sydney are used to investigate the ‘gap’ in spatial dispositions. Settling entails both practical accommodations to new and unfamiliar localities and an interweaving of cultural and ideological elements into the expanded everyday of migrant subjectivity. Language and speech are integral to spatial practices and provide means of referencing and evaluating ongoing social relations and trajectories. The ‘discourse space’ of interview accounts of settlement in Sydney and movements back to Hong Kong are closely examined, yielding an array of perceptions and representations of different, and contested styles of urban life. All the senses are brought into play in accounts of densities and absences in people’s everyday worlds. At the same time this thesis provides a perspective from which to interrogate contemporary interpretations of ‘transnational’ migration, suggesting the need for an analysis grounded in a specific economy of capacities and dispositions to appropriate social and symbolic goods.

Resumo: A arborização de vias urbanas pode se constituir num elemento bastante eficaz na amenização de altas temperaturas na camada intraurbana, através de mecanismos de sombreamento e evapotranspiração. Entretanto, entre os variados tipos de espécies arbóreas, quais seriam as mais indicadas para utilização na arborização das vias, a fim de mitigar a temperatura do ar no ambiente urbano? A utilização de ferramentas computacionais é uma alternativa para análise desta questão, tendo em vista que, o uso destes programas auxilia as pesquisas na área de planejamento e avaliação do ambiente construído, por meio da simulação de variados cenários. Um programa bastante utilizado para estudos de interação entre a vegetação e microclimas urbanos é o ENVI-Met, o qual, no entanto, não contém em seu banco de dados, parâmetros relativos a espécies brasileiras, em particular as de cerrado, o que pode gerar cenários microclimáticos incorretos. O objetivo desta pesquisa é propor um método para avaliação do potencial de sombreamento de espécies usadas em arborização de vias urbanas. Para tanto, foram realizados medições de radiação solar incidente sob copas de algumas espécies, usadas no sombreamento de vias urbanas da cidade de Bauru (SP), cujos resultados foram comparados com os parâmetros das mesmas espécies simulados pelo ENVI-Met.

Abstract: The afforestation of the urban streets can be a very effective element in the mitigation of high temperatures in urban layer through shading mechanisms and evapotranspiration. However, among the various types of tree species, which are the best indicated for use in street afforestation, to mitigate the air temperature in the urban environment? The use of computational tools would be an alternative to analyze this question, given that the use of these programs help in the research on planning and evaluation of the built environment through the simulation of various scenarios. A program widely used to study the interaction between urban vegetation and microclimates is the ENVI-Met, which, however, does not contain parameters in your database relating to brazilians species, particularly the cerrado species, which can create incorrect microclimatic scenarios. The aims of this research is to propose a method to evaluation of potencial shading of species used in afforestation of urban streets. For that, radiation measurements were performed in incident solar canopies of some species used in shading urban streets of the city of Bauru (SP), whose results were compared with the parameters of the same species simulated by ENVI-Met. From the processing, a tool was generated through which it is possible to extrapolate the results to select other species. Thus, it is expected that this method contributes to the indication of species that contain potential for mitigating the air temperatur... (Complete abstract click electronic access below)

Testo completoIt is generally accepted that tree roots can reinforce soil and improve the stability of vegetated slopes. Tree root reinforcement is also recognised in riverbanks although the contribution that the roots make to bank stability has rarely been assessed due to the reluctance of geomorphologists to examine riverbank stability by geomechanical methods that allow for the inclusion of quantified biotechnical parameters. This study investigates the interaction between alluvial soil and the roots of four southeastern Australian riparian trees. It quantifies the amount and distribution of root reinforcement present beneath typically vegetated riverbanks of the upper Nepean River, New South Wales, and examines the effect of the reinforcement on the stability of these banks. The ability of a tree to reinforce the soil is limited by the spatial distribution of its root system and the strength that the roots impart to the soil during shear. These two parameters were determined for the following four species of native riparian tree: Casuarina glauca, Eucalyptus amplifolia, Eucalyptus elata, and Acacia floribunda. The four species all exhibit a progressive reduction in the quantity of root material both with increasing depth and with increasing lateral distance from the tree stem. In the vertical direction there are two distinct zones that can be described. The first occurs from between 0 and approximately 15 % of the maximum vertical depth and consists of approximately 80 % of the total root material quantity. In this zone the root system consists of both vertical and lateral roots, the size and density of which varies between species. The second zone occurs below approximately 15 % of the maximum vertical depth and consists primarily of vertical roots. The quantity of root material in this zone decreases exponentially with depth due to the taper of individual roots. The earth reinforcement potential in terms of both geometric extent and the quantity of root material expressed as the Root Area Ratio (RAR) varies significantly from species to species. E. elata exhibited the highest values of RAR in soil zones beneath it while E. amplifolia reinforced a greater volume of soil than any of the other species examined. The increased shear resistance (Sr) of alluvial soil containing roots was measured by direct in-situ shear tests on soil blocks beneath a plantation. For three of the species (C. glauca, E. amplifolia, E. elata) Sr increased with increasing RAR measured at the shear plane, in a similar linear relationship. The shear resistance provided by A. floribunda roots also increased with increasing RAR at the shear plane but at a much greater rate than for the other three species. This is attributable to A. floribunda’s greater root tensile strength and therefore pull-out resistance, as well as its smaller root diameters at comparative RARs which resulted in a greater proportion of roots reaching full tensile strength within the confines of the test. Tree roots fail progressively in this system. Therefore determining the increased shear strength from the sum of the pull-out or tensile strengths of all individual roots and Waldron’s (1977) and Wu et al’s (1979) simple root model, would result in substantial over estimates of the overall strength of the soil-root system. The average difference between Sr calculated in this manner and that measured from direct in-situ shear tests is 10.9 kPa for C. glauca, 19.0 kPa for E. amplifolia, 19.3 kPa for E. elata, and 8.8 kPa for A. floribunda. A riverbank stability analysis incorporating the root reinforcement effect was conducted using a predictive model of the spatial distribution of root reinforcement beneath riparian trees within the study area. The model is based on measurements of juveniles and observations of the rooting habits of mature trees. It indicates that while the presence of vegetation on riverbank profiles has the potential to increase stability by up to 105 %, the relative increase depends heavily on the actual vegetation type, density, and location on the bank profile. Of the species examined in this study the greatest potential for improved riverbank stability is provided by E. amplifolia, followed by E. elata, A. floribunda, and C. glauca. The presence of trees on banks of the Nepean River has the potential to raise the critical factor of safety (FoS) from a value that is very unstable (0.85) to significantly above 1.00 even when the banks are completely saturated and subject to rapid draw-down. It is likely then that the period of intense bank instability observed within this environment between 1947 and 1992 would not have taken place had the riparian vegetation not been cleared prior to the onset of wetter climatic conditions. Typical ‘present-day’ profiles are critically to marginally stable. The introduction of vegetation could improve stability by raising the FoS up to 1.68 however the selection of revegetation species is crucial. With the placement of a large growing Eucalypt at a suitable spacing (around 3-5 m) the choice of smaller understorey trees and shrubs is less important. The effect of riparian vegetation on bank stability has important implications for channel morphological change. This study quantifies the mechanical earth reinforcing effect of some native riparian trees, thus allowing for improved deterministic assessment of historical channel change and an improved basis for future riverine management.

Testo completoA third olive trial, consisting of 3 olive groves was established according to randomised design. In the north and middle groves, 54 trees of 3 different cultivar were planted on a deep alluvial soil profile. In the south grove, 53 trees of 3 different cultivar were planted on a shallow clay soil profile. High mortality rates were recorded at all 3 groves during the first year, as a result of high salinity levels in irrigation water during the establishment period. Overall, most tree mortality was recorded at the south grove. Significantly higher growth performance occurred within the deeper alluvial soil profile at the north and middle groves, compared to the shallow clay soil profile in the south grove. Negligible olive fruit production occurred at the first site. At the second site, small quantities of olive fruit were produced during some seasons only. No olive fruit production occurred at any grove at the randomized site. Successful fruit formation appears directly related to tree health, as a function of water supply. Ripening of olive fruit occurred earlier than at other more temperate olive growing areas of Australia. Similar major and trace element deficiencies occurred at all sites, interpreted to be a function of universal alkaline ground-water conditions.
This study failed to confirm conclusively, whether European olive could be grown successfully in the semi-arid climate, typical of much of the rangelands area of Australia. As a result of the study however, successful growth in this environment is confirmed to be highly dependent on three factors. Firstly, availability of reliable irrigation waters of sufficient quality. Secondly, choice of suitable soil types. Thirdly, selection of suitable cultivars. Quality of olive oil produced from fruit appears to be influenced by local climatic factors The study also highlighted the issues of land tenure, current management attitudes and level of support within the local community as having a direct and significant impact on the trial.

Testo completoThe street forestation is an important environmental element that mitigates the effects which the process of urbanization on the environment causes. There are various factors that relate to the good development of trees in cities; among them are the management by the government, the residents’ perception and the environmental conditions in which the species are evolving, especially soil conditions. Thus, the present study aimed to evaluate relationships between soil, residents and the arboreal species regarding the urban forestry in Pato Branco. Therefore, it was delimited as study area five neighborhoods with different characteristics of location and income in the county: Centro, La Salle, Pinheiros, Aeroporto e Veneza. Lagerstroemia indica L. (crape myrtle), Schinus molle L. (california pepper tree), and Bauhinia variegata L. (orchid tree) were the species studied, chosen by their representation in the forestation of the city. It was evaluated the soil used by 114 tree individuals in the five neighborhoods and 123 semi-structured questionnaires were administered in order to understand how the residents of these neighborhoods perceive the urban forestation. The survey results indicate that there is a great variability concerning the characteristics of the soils studied which present incorporation of anthropogenic materials, inversion of horizons and absence of decaying organic layer. The results of sieve analysis showed that despite the variability of textures in evaluated points, most soils analyzed fit in the texture class of very clayey or loamy. The urbanization process in the city of Pato Branco has fundamentally altered the chemical properties of soils of the studied species, since most of them showed relative enrichment in exchangeable bases, which antagonizes with the low natural fertility of soils in Pato Branco. There were also chemical differences regarding the impermeable soils by pavement and the ones not impermeable, the impermeable soils presented lower levels of organic matter and higher values of Ca and pH. The soils in the center area seem to be the most affected by the urbanization process, where there is a higher percentage of sand added to the soil, and greater amount of waterproofing materials coming from civil construction. Regarding the perception of residents, in general the interviewees seem to recognize the importance and function of urban forestation. Among the problems perceived by the research subjects, many are technical in nature and could be avoided through an efficient planning. Other observed problems are cultural, more complex and difficult to solve. Residents prefer mainly the species that have attractive such as exuberant blooms and they seem to appreciate trees that they chose by themselves to have in front of their homes. Therefore, it is important to adjust the strategies adopted by the government to the local needs, preserve the cultural aspects, and contemplate besides the technical aspects related to forestation, other aspects in a ludic way, to attract and encourage people to commit themselves with forestation.
