AN EXPLORATORY STUDY OF THE EVOLUTION OF URBAN GREEN SPACES IN LISBON USING DIACHRONIC ANALYSIS OF ORTHOPHOTO MAPS

Green urbanism, namely in the form of consolidated urban green spaces (UGSs), has gained traction along with the reformist impetus of urban design, based on the ideal of efficient, functional, sustainable cities that promote a better quality of life for their citizens and on the notion of making urban expansion compatible with natural resources. Using a diachronic analysis (1995–2020) of the orthophoto maps of 38 UGSs included in the last version of the main municipality’s legislation, framed within the Plano Director Municipal (PDM), whose first version was approved in 1994, we assessed the situation and evolution of the UGSs in the centre of Lisbon, Portugal. We conclude that with fewer or more incidences, depending on the periods analysed, the structure of UGSs in the centre of Lisbon has undergone significant changes, whether in terms of the implementation and requalification of existing UGSs or in terms of the increment and quality of UGSs (space created), thus respecting to a lesser or greater degree the strategic lines defined in various plans, as is the case of the PDM itself, but also of other important documents, such as the Carta Estratégica 2010–2024, Estratégia de Reabilitação Urbana 2011–2024 and Estratégia Regional de Lisboa 2030.

EVOLVING RESEARCH METHOD IN THREE-DIMENSIONAL AND VOLUMETRIC URBAN MORPHOLOGY OF A HIGHLY DENSE CITY: ASSESSING PUBLIC AND QUASI-PUBLIC SPACE TYPOLOGIES

An appropriate urban density is a vital part of a sustainable urban fabric. However, when it comes to measuring the built urban fabric and how people walk through it and use, a difficulty has been observed in defining applicable measurement tools. With the intention of identifying the variables that will allow the best characterization of this fabric and movement, a multi-variable analysis methodology from the field of artificial intelligence (AI) is proposed. The main objective of this paper is to prove the capacity of AI as an evolving research method in urban morphology and specifically to evaluate the capacity of such a methodology to measure the way in which people travel through defined multi-levels of typologies of public urban space. The research uses the case of Hong Kong as a dense city that is three-dimensionally activated in terms of its public realm, not just at street level, but also via below ground subways and upper-level walkways, public and quasi-public spaces. This includes the three-dimensional volumetric assessment of public and quasi-public space typologies within a highly dense city. For the purpose of the study, a characterization and term definition of these spaces has been further developed: “Junctions”, “Landmarks”, “Intersections”, “Districts”, “Passages” and “Lobbies” (both outdoor and indoor) based on Lynch’s 5 main key elements (District, landmark, path, edges, node). The results obtained using AI prove to be more robust and rational than those based on a more limited range of tools, evidencing that using AI can offer operational opportunities for better understanding of morphological and typological evolution within the vertical and volumetric built urban fabric.

SOCIAL PRODUCTION AND CONSUMPTION OF SPACE: STUDY OF PUBLIC-MARKET IN BANDUNG, INDONESIA

This paper aims to examine the role of architecture in social production and consumption of space, using public markets –architectural artifacts with rich social contents– as cases. This research adopts Low’s (2017) concept of social production of space and Dovey’s (2010) social constructivism of place to uncover the social production and consumption of public markets’ space. Cihapit and Pamoyanan market in Bandung, Indonesia, are selected as research cases, due to their cultural contents, appealing to consumers from middle to upper class society. It is found several roles of architecture in social production and consumption of public market space: building typology and morphology signifies historical context of development; architectural buildings contributes to formalize trading activities and elevating social class of market traders; commodities zoning is organized based on functional and socio-historical consideration; spatial intensity is determined by access and commodities zoning; informal atmosphere emerges as a distinctive advantage of public markets; and spatial quality is relative depends on governance capacity. Although normative criteria for good design can be formulated, in practice, spatial quality of public market is relative and depends on its capacity for spatial governmentality. By exploring social production and consumption of space and place provides broader perspective on the social practices of architecture, emphasizing its contribution for social and humanity studies.

THE DIVIDED BRAIN AND WAYS OF BUILDING THE WORLD: PARALLELS IN THE THOUGHT OF IAIN MCGILCHRIST AND CHRISTOPHER ALEXANDER

What might have led to the fundamental changes in the built environment during the 20th century? While factors such as postwar reconstruction, urbanization, industrialization, shifts in style, or socio-political changes are surely involved, there may be deeper influences that are associated with the structure and dynamics of the human brain. Iain McGilchrist’s hemisphere hypothesis proposes that the differences between the left and right hemispheres are not functional but embody opposing approaches to the world: the left sees an atomized world made of things to be controlled and manipulated for survival; the right sees an interconnected world of wholes with which it is deeply related. McGilchrist observes that in recent centuries, there has been an increasing shift in the West towards the left hemisphere’s approach. Christopher Alexander’s lifelong quest for wholeness in the built world resonates with McGilchrist’s observations as applied to the field of architecture. Alexander observed that today’s built environment is an expression of our civilization seeing the world as a giant mechanism made of parts rather than an indivisible whole. In response, Alexander developed design methods that approach the world as a unified whole and the building of new places as a further unfolding of that whole.

READING THE PAST: ANALYSIS OF THE IMPACT OF PREVALENT PANDEMICS ON CITIES

Throughout history, dozens of epidemics have appeared cyclically, often causing devastating effects. Some of them, such as plague, cholera, and tuberculosis, have led to significant social, economic, and political consequences, with evident repercussions on cities and architecture. In this regard, urban planning has played an essential role in improving life expectancy and limiting the spread of epidemics. This work aims to study the influence of prevalent pandemics on architecture and urbanism over the centuries to comprehend their response and adaption to new health and social requirements. Through a process of investigation and in-depth examination of the literature review, it has been possible to understand the impact of pandemics in cities. The appearance of the first preventive measures during the plague period, the urban interventions to combat the cholera outbreak, and the neat architectural features adopted following the appearance of tuberculosis are witnesses to this process. Professionals and academics are reflecting on the challenges of the Covid-19 pandemic, which will affect the practice of architecture and urban design. Thanks to the results obtained, it will be possible to reflect on the impact of the pandemic on contemporary cities, understand their potential resilience and hypothesise future strategies.

GLOCALIZATION CHALLENGES AND THE CONTEMPORARY ARCHITECTURE: SYSTEMATIC REVIEW OF COMMON GLOBAL INDICATORS IN AGA KHAN AWARD’S WINNERS

Local reports from different international societies have considered the achievement of the successful Glocalized architecture model in line with the 2030 UN Sustainable Development Goals (SDGs). The Aga Khan Cultural Foundation’s International Program for Islamic Architecture has also prioritized the understanding of the success drivers in architectural projects. This study aimed to detect the potentials of the common global indicators to access qualitative design assessment through analyzing the Aga Khan Award’s reports. The selected methodology in the present study is a quantitative approach using the systematic content analysis and coding techniques for qualitative data obtained from the technical. The physical, non-physical, modern, and traditional factors that have contributed to the success of the works as well as their combinations were extracted and analyzed using Sensible and Abstract international, national, and local indications. There is a relative superiority for Sensible indications (A combination of modern and physical factors). The hybrid data distribution provides the ground to assess the works, and this can be used to manage the globalization challenges in the contemporary architecture of Muslim societies.
