Layers of Meaning and Evolution of Cultural Identity: The Case of Wind Towers in Dubai

Place identity is an important constituent of general cultural identity, in that it provides its share of continuity, sustainability, and character to the built environment. The image of cultural heritage is stored knowledge that reflects the identity of a specific culture. In the formation of a place, some features gain identity with the environment. This study aims to explore the evolving image formation of wind towers in Dubai, and how this image is related to the concept of meaning and cultural identity of the place. This study focuses on the process of place identity formation and its relation to the evolving cultural values of society, as well as how it is applied to the changing meaning of cultural heritage objects. Based on the value assessment approach, different examples of wind towers, taken from either traditional houses or contemporary buildings influenced by the local architecture in Dubai, the author attempted to study how the interpretation and meaning of wind towers has evolved through time, thus influencing the cultural identity of Dubai city. This study is based on qualitative research. It concludes that a wind tower, as a cooling device, represents a unique example of an evolving creative process of architectural expression, resulting from the social and cultural complexity of the Persian Gulf in the early twentieth century. They were introduced through commercial exchange, adapted by the mercantile community, and integrated into local cultural systems—thus creating new architectural features and urban character—and reintroduced as a modern symbol of cultural identity for Dubai and the UAE.

Getto bardzo miejskie, czyli raz jeszcze o określeniach warszawskiej żydowskiej dzielnicy zamkniętej

The article examines the specific linguistic expressions used to name the phenomenon of the Warsaw ghetto established in November 1940 and existing until May 1943. The common denominator of the terms analyzed here is their semantic components that directly refer to the urban character of the ghetto. The range of meanings of the expressions presented here and their simultaneous urban connotations reflect how Jewish and non-Jewish residents of Warsaw who were directly affected by the city’s division conceptualized the phenomenon of the ghetto. The article supplements the already known diagnoses concerning the metaphors of the Warsaw ghetto and provides a commentary on a more general level about ways of naming the space of oppression.

Cultural Jugaad in historic city transformations: India

Several historic Indian cities have managed to retain the original urban character by using readily available materials, craftspeople, and cultural traditions despite increasing urban transformations. This notion of sustaining/preserving/continuing certain cultural elements and rituals has survived in various forms in the last two centuries. Historic cities showcase their living heritage at the global level and are exemplars for studying the strong linkages within traditions and indigenous modes of preservation. In such situations where stakeholders have centuries of association with the site, it is essential that professionals look beyond conventional solutions to better understand local perceptions and thereby establish the appropriateness of any urban level interventions. This article draws from various urban conservation works carried out in the historic cities of Rajasthan over the last two decades. It illustrates the discoveries and challenges in understanding the traditional local mindset for working in such areas. The indigenous methods practiced in these historic living cores are often at variance with the norms and logics of Western city planning being followed in post-colonial India. Examples in the cities and settlements of Jaipur, Udaipur and Ajmer, feature in this article, highlighting the urgent need to understand the local community mindset and the Indian approach to solutions for rapidly modernizing historic urban centres

Religion and Classical Europe, Twelfth Century bce–600 ce

In a history of religion and Europe classical Antiquity is both an example of difference, that is, the polytheistic systems of Greek and Roman religions, and the beginnings of the monotheistic religions, which became the mainstream in medieval and modern Europe. Drawing on the rituals, symbols, and patterns of polytheism as the legacy of the palace cultures in the Ancient Near East and Greece (until 1200 bc), the city-states (poleis) adapted these to non-autocratic societies (polis-religion). In the empires of Hellenism and the Roman Empire itself, religions were not part of a power structure (e.g. a ruler-cult). Rather their urban character allowed a plural neighbourhood, in which the monotheistic religions were well integrated. In late Antiquity a long transformation formed the Middle Ages, when with the rise of Islam the Mediterranean became divided into three parts: the Islamic south, Greek Orthodoxy in the east, and Latin-speaking ‘Europe’ in the north-west.

Urban Morphometrics and the Intangible Uniqueness of Tangible Heritage. An Evidence-Based Generative Design Experiment in Historical Kochi (IN)

Asia is urbanising rapidly. Current urbanisation practices often compromise sustainability, prosperity, and local quality of life while context-sensitive alternatives show very limited impact. A third way is necessary to integrate mass-production, heritage, and human values. As part of UNICITI’s initiative, A Third Way of Building Asian Cities, we propose a scalable and replicable methodology which captures unique morphological traits of urban types (i.e., areas with homogenous urban form) to inform innovative large-scale and context-sensitive practices. We extract urban types from a large set of quantitative descriptors and provide a systematic way to generate figure-grounds aligned with such urban types. The application of the proposed methodology to Kochi (IN) reveals 24 distinct urban types with unique morphological features. Profiles, containing design-relevant values of morphometrics, are then produced for a selection of urban types located in the historical district of Fort Kochi/Mattancherry. Based on these, figure-ground design demonstrations are carried out in three sample sites. Outcomes seem aligned with the urban character of their respective types, while allowing distinct design expressions, suggesting that the proposed approach has potential to inform the design in historical/heritage areas and, more broadly, the search for a Third Way of Building Asian Cities.

Urban Brownfields: Origin, Definition, and Diversity

Brownfield is a polysemic notion that encompasses a whole range of diverse spaces. Although there is no official definition at the European level, an emerging consensus has arisen around the urban character of brownfields and the need for intervention. Indeed, their location within metropolitan areas represents a strategic opportunity to densify and rejuvenate the urban fabric at the neighbourhood scale. Hence, we propose a definition of urban brownfields that is flexible enough to optimize the potential development of abandoned sites and precise enough to enable framing the discussion. Then, we take a look at the diversity of urban brownfields in European metropolitan areas by briefly explaining the factors that cause a site to become a brownfield and then attempting to classify different types of urban brownfields. The proposed classification aims to create a non-exhaustive reference framework by offering in-depth knowledge of the urban brownfield and regeneration projects phenomenon across Europe, without setting its meaning in stone.

Circulating value: convergences of datafication, financialization, and urbanization

Much scholarship has revealed the interrelationships of urbanization and financialization of cities in the past half century. However, these twin processes are modulating with the advent and application of digital platforms towards the production and experience of urban life. This paper demonstrates how the datafication process of platform urbanism and smart city projects is deeply intertwined with processes of financialization and urbanization. Though materially distinct, these processes converge over a shared purpose to instigate and accelerate the circulation of value in capitalist urban production. This paper examines the urban character of digital economic circulation and the increasingly financialized datafication of urban infrastructures. In foregrounding the circulation of value, datafication both conditions and is conditioned by financialization and urbanization.

Validation of Sentinel-5P TROPOMI tropospheric NO2 with airborne imaging, ground-based stationary, and mobile DOAS measurements from the S5P-VAL-DE-Ruhr campaign

<p>Airborne imaging DOAS and ground-based stationary and mobile DOAS measurements were conducted during the ESA funded S5P-VAL-DE-Ruhr campaign in September 2020 in the Ruhr area. The Ruhr area is located in Western Germany and is a pollution hotspot in Europe with urban character as well as large industrial emitters. The measurements are used to validate data from the Sentinel-5P TROPOspheric Monitoring Instrument (TROPOMI) with focus on the NO<sub>2</sub> tropospheric vertical column product.</p><p>Seven flights were performed with the airborne imaging DOAS instrument, AirMAP, providing continuous maps of NO<sub>2</sub> in the layers below the aircraft. These flights cover many S5P ground pixels within an area of about 40 km side length and were accompanied by ground-based stationary measurements and three mobile car DOAS instruments. Stationary measurements were conducted by two Pandora, two zenith-sky and two MAX-DOAS instruments distributed over three target areas, partly as long-term measurements over a one-year period.</p><p>Airborne and ground-based measurements were compared to evaluate the representativeness of the measurements in time and space. With a resolution of about 100 x 30 m<sup>2</sup>, the AirMAP data creates a link between the ground-based and the TROPOMI measurements with a resolution of 3.5 x 5.5 km<sup>2</sup> and is therefore well suited to validate TROPOMI's tropospheric NO<sub>2</sub> vertical column.</p><p>The measurements on the seven flight days show strong variability depending on the different target areas, the weekday and meteorological conditions. We found an overall low bias of the TROPOMI operational NO<sub>2</sub> data for all three target areas but with varying magnitude for different days. The campaign data set is compared to custom TROPOMI NO<sub>2</sub> products, using different auxiliary data, such as albedo or a priori vertical profiles to evaluate the influence on the TROPOMI data product. Analyzing and comparing the different data sets provides more insight into the high spatial and temporal heterogeneity in NO<sub>2</sub> and its impact on satellite observations and their validation.</p>
