Architecture and site: a field research center for the studies of environmental science, horticulture, landscape architecture, and forestryChi, Curtis H. January 1993 (has links)
The relationship of building to site is the most fundamental aspect in the creation of architecture. As man is a product of nature and his environment the way in which he chooses to after that environment in the process of building reveals not only his attitude towards his physical surroundings, but his purpose and justification for dwelling there. Not all attitudes will be the same, just as purpose will vary from person to person and structure to structure.
Mario Botta has said, “The first step in the architectural act is taking possession of the site. It is a conscious act of transforming a unicum, an awareness that grounds the new intervention in the geography, history, and culture of a particular site. The architecture is the constriction of this site. There can be no indifference toward the site. It is the very territory of architecture as well as the primary condition determining the laws by which one must build.”
Within the scope of my project I hoped to define this awareness within myself, this conscious act of defining and creating architecture against a background that demands the site be recognized as a primary generator of architectural form and attitude. / Master of Architecture

ASSEMBLY OF ARTHROPOD COMMUNITIES IN RESTORED PRAIRIE, OLD FIELD AND MONOSPECIFIC STAND OF PHALARIS ARUNDINACEA: A FUNCTIONAL PERSPECTIVEEric M Kelleher (6642413) 11 June 2019 (has links)
<p>Effects of prairie restoration on arthropod diversity was investigated
at Gabis Arboretum, Valparaiso, Indiana. A total of
35,408 arthropods belonging to 13 taxa in the restored prairie (RP1 and RP2), old field (OF), and monoculture stand of Phalaris
arundinacea (reed canary grass – RCG) sites, were captured, counted, and compared. The enhanced plant species diversity in the restored prairies did not appear to promote the diversity of
arthropod taxa. However, the restoration led to a more balanced composition of arthropod functional
groups and thus elevated the diversity of functional groups.
The arthropod assemblages in the three sites diverged clearly according to my canonical correspondence analysis (CCA)
ordination. Pollinator abundance was greatest at RP and least at RCG site, positively correlating with
greater forb diversity, and suggesting greater potential for nectar feeding and pollination
potential at RP sites. Herbivore abundance was greatest at the RP sites, positively correlating with
increasing plant species diversity. Predator abundance
was significantly greater at the RCG site compared to the OF and RP sites; it was positively correlated with greater C3 grass cover, a
characteristic of the structurally homogenous RCG site, and negatively correlated with
increasing plant diversity and forb cover, a characteristic of the diverse and more structurally
complex RP sites. Given the apparent non-random distribution of arthropods among the field types,
my results suggest plant species composition has a significant effect on arthropod
assembly. The monoculture grass stand was found to have a predator dominated arthropod community supported by
a small, diverse herbivore community. It is
concluded that the prairie restoration has resulted in alteration of arthropod communities supporting greater pollinator and herbivore
abundance and a more balanced ratio of herbivores to predators due, in part, to increased
plant structural diversity.</p>

Návrh udržitelné městské struktury 21.století v rámci České republiky / Design of sustainable urban structure of the 21st century in the Czech RepublicBoháčová, Denisa January 2020 (has links)
This thesis is solving the design of a sustainable urban structure of the 21st century in Brno, in the area of Kasárna in Černá pole. The thesis is trying to create a neighborhood that would serve not only to the needs of the millennials, but of every generation. It is trying to build a city for the people. I am designing the new development as a lively, diverse and flexible neighborhood which considers the history of the area. I am conserving its rectangular shape in the urban footprint. I am designing a city with clearly defined public spaces. I am opening the neighborhood to the public and therefor allow it to newly connect with neighboring districts. The goal of the design is to create a modern neighborhood that will function as a new subcenter of the city of Brno.

(RE)DEFINE GROWTH : How to Connect Ön and the City while Preserving, Emphasising and Intensifying the Green, Rural and Recreational QualitiesKassberg, Anna January 2017 (has links)
Ön is an island in central Ume River. Today Ön is a rural, green place with key habitats and historical values. In 2008 the municipality took the decision to exploit it by building city there. The decision was preceded by the emerging growth target, for Umeå, to become 200,000 inhabitants in 2050. The research material for this paper consists of legal documents, reports, literature, interviews, and own observations. It can be divided into three main parts. The first part, which is the ‘growth discourse’, is investigated through documents concerning political strategies and influences from within the field in relation to Umeå as a city. The second part consists of research around the ‘image’ of Norrland and the third part focus on questions involving well-being through nature and the concept of Ecosystem Services, in relation to Ön. In this paper, I advocate for an alternative plan concerning Ön and its unique set of qualities: the rural, historical, and nature dominated atmosphere adjacent to the city of Umeå. I argue that the value of this land is greater in its natural vesture, than it would be with added asphalt and concrete. The values of concern are non-monetary, but might as well become monetary in the more long-term scenario. There is mounting evidence of benefits derived from nature, when it comes to human well-being, and further that ecosystems provide services of major importance to us. Ecosystem Services are the benefits people obtain from ecosystems. Ön possesses many of these services today. It holds potential for further cultivation and capacity to become amplified as a recreation area in central Umeå. The objective of this master thesis is to define and validate the qualities of Ön; and further, to develop a programme of possible interventions, in order to preserve and intensify the present atmosphere. This is conducted by identifying Ecosystem Services in the current context; and ways to enhance them, in order to propose an alternative plan for Ön.

Podrobný urbanistický návrh využití území Sportovní, Drobného, Tř. gen. Píky, Porgesova / Complex urban study of the public space Sportovní, Drobného, Tř. gen. Píky, PorgesovaPolonyankina, Natalia January 2016 (has links)
Due to diverse surrounding area and position of isolated large objects suggest itself solving of conception by stages. In the southern part there were suggested new sports halls which have a long term tradition in this area. These buildings keep to the axis of Sportovní street and they are reacting to existing buildings on the other side. In the northern part at the shopping centre it was necessary make the place accesible and grass the place over and use the opportunity of the large space. In the northeastern part there is housing development and it reacts on the FRRMS building and it makes confotable enviroment for living. Buildings FRRMS together with rampats and bushy vegetation are isolating flat buildings. Effort to connect existing and establish new resulted in the simple solution solution that does not disrupt the neighborhood, on the contrary, trying to blend in with the city and calm the chaos in this area.

Le jardin botanique de Bruxelles (1826-1912) Miroir d'une jeune nation.Diagre, Denis 20 April 2006 (has links)
L’histoire du Jardin botanique de Bruxelles offre l’opportunité de prendre le pouls de la capitale et de ses développements successifs ; de la bourgeoisie du XIXème siècle, de ses passions et de ses fantasmes ; de la science nationale et internationale ; des rêves coloniaux qui habitèrent les souverains belges ; bref de la société belge dans ses multiples composants… quand elle n’entrouvrait pas la porte de l’intimité psychologique de certains intervenants majeurs du passé scientifique national.
En effet, le Jardin botanique fut d’abord l’expression d’une société anonyme créée sous le régime hollandais (1826) : la Société Royale d’Horticulture des Pays-Bas. Cette dernière devait enfin doter la capitale méridionale du pays d’un indispensable marqueur de sa modernité, à moindres frais pour la couronne. Dans ce modus operandi se lisaient la passion bourgeoise pour la nature (surtout exotique), certes, mais aussi son utopie, laquelle faisait dépendre le bien être de la société de l’esprit d’entrepreprise d’une classe. Il s’agissait d’une des premières sociétés anonymes belges, et l’immaturité de cet outil se paierait bien vite.
Alors qu’il avait été inspiré par le Jardin des Plantes du Muséum d’Histoire Naturelle de Paris – archétype de l’institution scientifique nationale totalement soutenue par l’état – le jardin de Bruxelles revêtit une forme commerciale qui devait bien le servir, lorsque la crise qui suivit la Révolution de 1830 frappa les finances publiques du nouvel état belge. Dès ce moment, le Jardin botanique se lança dans une recherche effrénée de revenus, laquelle ne cesserait qu’avec le rachat du site par l’état belge, en 1870. Unanimement considéré comme magnifique, il n’avait survécu jusque là que grâce à l’écrin qu’il offrait aux réjouissances bourgeoises de la capitale, grâce à la vente d’une partie de sa surface à la faveur de la construction de la Gare du Nord, et à des augmentations successives des subsides versés par le gouvernement et par la capitale. En réalité, la science n’avait alors jamais vraiment élu domicile à la Porte de Schaerbeek… tout au plus avait-on tenté de la singer pour feindre de mériter les subventions nationales que les Chambres devaient approuver. La beauté remarquable de la propriété, sa fonction sociale d’écrin pour la vie événementielle bruxelloise, et sa fonction symbolique de révélateur d’état de civilisation, avaient été les clefs de sa longévité.
Le site fut donc racheté en 1870, à la suite d’une entreprise de persuasion, tenant parfois du lobbying, menée par Barthélémy Dumortier (1797-1878), célèbre homme politique catholique, et botaniste de renom. Il avait pour objectif de monter un équivalent belge des Royal Botanic Gardens de Kew, sur les ruines de ce jardin que la bourgeoisie avait abandonné à l’Etat, contre une somme ridicule et en sacrifiant les bénéfices de ses actionnaires.
Dumortier voulait donc créer un grand centre voué à la taxonomie, et avait fait acheter le célèbre herbier brésilien de F. von Martius à cette fin.
Après des années d’incertitude, marquées par des querelles internes, parfois fort menaçantes, le Jardin botanique de l’Etat échut à François Crépin, l’auteur de la fameuse Flore de Belgique.
Le Rochefortois ne cesserait de tenter de déployer son institution, parfois avec succès, mais elle pâtissait d’un handicap de taille : des liens trop étroits avec la Ville de Bruxelles et son université, bastions libéraux et maçonniques. Il en découla, dans une série de ministères uniformément catholiques, une intrumentalisation du Jardin botanique, teintée de mépris, à des fins politiques, et un sous- financement chronique peu propice à la modernisation scientifique de l’institution.
Le secours vint du besoin d’expertise scientifique et agronomique dont le Congo léopoldien avait cruellement besoin. Sous le bouclier du souverain de cet état indépendant, une institution scientifique belge trouva protection contre la malveillance des ministres belges, des milliers de feuilles d’herbier qui lui permirent de pratiquer légitimement une discipline bien essoufflée (la taxonomie), de s’y faire une niche et de devenir un des plus grands centres mondiaux en matière de botanique africaine. Ainsi, la colonisation donna-t-elle une base de replis à de grands fonds scientifiques, alors que les universités s’étaient emparées de la physiologie, et des nouvelles disciplines prometteuses. Ces bases de données sont aujourd’hui impliquées, en première ligne, dans les recherches suscitées par la grande inquiétude écologique contemporaine.
Miroir de la Belgique, le Jardin botanique de Bruxelles refléta beaucoup de ses gloires et de ses tourments, de ses querelles politiques et philosophiques, et même de ceux qui eurent le Congo pour cadre. Son rayonnement, jadis comme aujourd’hui, doit beaucoup à ce continent. Ainsi peut-on légitimement affirmer que le Jardin botanique fut et reste un enfant de l’Afrique.
