Über dieses Buch

In the current panorama of urban growth and planning in many urban territories of western societies, open spaces are residual spaces of urban occupation or are reserved for eventual occupation. Open spaces have been viewed in this manner in the earlier stages of the compact city and especially now, in a time of the dispersed territories characterized by discontinuity, heterogeneity, and fragmentation.

The disciplinary perspectives of ecology, geology, landscape architecture, and urbanism, but also public opinion, have for some time promoted the conservation and protection of the most valuable natural spaces, and efforts have been made to remove such spaces from the real estate market. However, such positions, usually radical, are insufficient for territorial equilibrium and inevitably lead to the progressive disappearance of valuable natural spaces.



Chapter 1. Introduction

This book proposes an interdisciplinary method of urbanistic intervention through the planning of the system of open spaces and demonstrates possible concrete project strategies for the restructuring of urban territories. Open spaces are considered to play a valued role in spatial planning on the basis that they are a system, with its own values, and the planning of the system of open spaces may have the potential to restructure the territory in terms of providing a new structure for urban occupation whether existing or yet to come.

Chapter 2. Conceptual Questions

This chapter analyzes theoretical contributions that serve as a basis for the development of the proposed method.

Chapter 3. Characterization of the Territorial Unit

The purpose of the general characterization of the territorial unit is to de fine the main aspects of a study area, which will be important for subsequent analyses. The characterization is an approximation of the area rather than a detailed study, and it comprises an introduction to the area and its territorial situation and the relief, climate, hydrography, infrastructure (i.e., roadways, urban services, and public transportation), vegetation, urban land use, and population characteristics.

Chapter 4. Recognition of Open Spaces and Their Urban Context: Open Spaces to Be Analyzed and Roles that They Can Play in Structuring Urban Occupation

The present analysis allows the identification and characterization of territorial open spaces and the urban dynamics of which they are part to recognize the origins of the fragmentation of the urban territory and consequently their processes and elements (e.g., open spaces, settlements and infrastructure, and especially roadways) that can offer a perspective on the open spaces to be analyzed and the roles that they can play to reverse this reality and structure the urban occupation. Thus, the analyses consider the spatial and functional relationships established among open spaces, settlements, infrastructure, and planning over time as key factors in the planning of the system of open spaces and the restructuring of the territory. The bases of the analyses are as follows.

Chapter 5. Analysis and Evaluation of the Attributes of Open Spaces: Identifying Possible Spaces of Project Opportunity and Their Situation in the Territory

This chapter analyzes attributes of open spaces: the biophysical support, visual perception, accessibility, and links to planning rules. The proposal is to evaluate each attribute according to specific parameters and a scale of values. It is thus possible to design an initial approach that can designate territorial open spaces that are most suitable to be preserved as unoccupied areas and those that can be occupied under certain conditions, as part of a system of open spaces. The analysis is based on the following parameters.

Chapter 6. Proposals of Concrete Project Strategies: Planning the System of Open Spaces and Restructuring the Urban Territory

This final chapter, on the basis of the previous analysis, proposes project strategies that allow the planning of the system of open spaces and the restructuring of the urban territory, thus creating combined strategies for open and occupied spaces and reinforcing the relationship between planning and design. The objective is to maintain and develop the dynamics of the open spaces and relate open spaces to each other and structure the urban occupation. Thus, the project strategies are suggestions for the planning of open spaces and an opportunity to restructure the territory, and involve the following.

Systemische Notwendigkeit zur Weiterentwicklung von Hybridnetzen

Die Entwicklung des mitteleuropäischen Energiesystems und insbesondere die Weiterentwicklung der Energieinfrastruktur sind konfrontiert mit einer stetig steigenden Diversität an Herausforderungen, aber auch mit einer zunehmenden Komplexität in den Lösungsoptionen. Vor diesem Hintergrund steht die Weiterentwicklung von Hybridnetzen symbolisch für das ganze sich in einer Umbruchsphase befindliche Energiesystem: denn der Notwendigkeit einer Schaffung und Bildung der Hybridnetze aus systemischer und volkswirtschaftlicher Perspektive steht sozusagen eine Komplexitätsfalle gegenüber, mit der die Branche in der Vergangenheit in dieser Intensität nicht konfrontiert war. Jetzt gratis downloaden!
