The impact of urban transformations on the morphology of streets networks
2017
This research takes place in the field of quantitative analysis of historical streets networks.During the last decades, many studies have used network analysis or space syntax approachin a diachronic perspective, either to observe the interdependence between networkconfigurations and land-use, or to explore the link between network configurations and knownurban phenomena, such as densification, dispersal or expansion. These researches often focuson one single transformation rather than on the long time evolution of networks. In this work,we will explore the evolution of the street network of Paris, between 1300 and 1871, and linkthis evolution to all the transformations that occurred in the…
Strategy to re-active an urban landscape
2018
To re-activate an urban landscape, through a complex system of relationships, needs a goal: trigger a course of identification based on cultural heritage like an “ID card”. To do this, without losing the historical common memory, culture doesn’t have to be only for the “elite” but has to begin the raw nerve of the development. When Kevin Lynch wrote about wayfinding, it was not for tourists but for inhabitants whom daily live in that place: the field of “orientation” was essential for him like it was for Camillo Sitte. This theorist of urban planning (not fully understood) said that “the space and the city are important if they are active” and Wieczorek explains that “active” means the rule…
Urban mobility and the spatial distribution of economic activities in Rio de Janeiro (Brazil)
2017
International audience; In developing countries such as Brazil, the economic growth is gradually improving the population's standard of living, resulting in major impacts on urban mobility, particularly with regard to motor vehicle access. Between 2001 and 2012, the total growth of the car fleet in Brazil was around 3.5 million (Rodrigues, 2013), with 5.4% of this growth only in the Metropolitan Area of Rio de Janeiro. Presently, the city is experiencing severe congestion episodes (Beyer, 2012), due to saturation of the main roads, and a fragmented and inefficient public transport system.For a country in economic development in the 21st century, it is very important to plan and monitor the …
Relationships between Heavy Metal Concentrations in Greater Celandine (Chelidonium majus L.) Tissues and Soil in Urban Parks
2023
Anthropogenic ecological ecosystems create favourable conditions for the growth of the nitrophilous medicinal species Chelidonium majus in six urban parks in Southern Poland. This study focuses on the concentrations of trace elements in the soils, leaves, stems, and rhizomes of greater celandine. The soil samples were taken only in the humus horizon (A), which averaged approximately 15 cm in thickness under the clumps of Ch. majus. Regarding the reaction, the soil samples tested can be described as slightly acidic (5.6–6.8 in KCl) to alkaline (7.1–7.4 in H2O). Organic carbon content at all sites is high, ranging from 3.2% to 13.6%, while the highest total nitrogen (Nt) content is 0.664%. Th…
La contestación a los próceres. Pugna de facciones y desórdenes en Valencia (1376-1478)
2021
La intermitencia de los ataques verbales y escritos contra las decisiones de gobierno de la ciudad de Valencia a lo largo de un siglo se inscriben en una dinámica absorbente, liderada por partidos rivales de la oligarquía, capaces éstos de asumir reivindicaciones grupales ajenas y de arrastrar a parte de los ciudadanos y de los menestrales bajo fórmulas clientelares. Las circunstancias concretas de las protestas superaron los cauces institucionales previstos en una asamblea municipal renovada anualmente y con amplia representación social, la cual se demostró más como plataforma para la adhesión de los vecinos respecto a los líderes de la sociedad política y menos como órgano de discusión po…
Social Media as Platform for Stimulating Urban Changes
2016
Images have always been an important part of city planning – current images of place, images with planned improvements, maps and sketches. Some time ago all that was a private property of stakeholders like planner and client. But nowadays this confidentiality rather much has vanished – no copyrights or competition is noteworthy. Plans do not have their privacy anymore. They are exposed even before they got implemented. This article will display why city planners share the images of their ideas, of their dreams in public (mostly in blogs and social networks) – why it is important for them and what kind of feedback they are waiting for. This article is based on case study where 12 respondents…
Città e organismi territoriali. Verso un approccio olistico alle crisi dell’Antropocene
2021
From the second half of the nineteenth century, urban planning was understood, according to a top-down approach managed by government systems, as a cure for the city affected by the disease, injustice, and violence. This approach, aimed at regulating the behaviour of producers in cities and territories, aims at favouring the strongest economic and social actors to the detriment of the weakest social tissues. Today, the various factors of economic and social crisis, which act on a global scale, have made the picture of inequalities even more complicated and uncertain than in the past. Consequently, the technocratic responses provided by central governments are no longer enough and indeed som…
Dall’iper–densificazione all’abbandono: la negazione della qualità della vita nella città moderna
2021
A partire dall’Ottocento si assiste ad un fenomeno che porta le città europee ad ingrandirsi ed espandersi. Non si tratta solo di un’estensione territoriale, ma anche di un incremento della densificazione dovuto agli ingenti spostamenti di popolazione dalle campagne ai centri urbani. Il fenomeno della densificazione non deve essere inteso solo come rapporto tra la superficie e il numero degli abitanti, ma anche come complessità delle relazioni sociali ed è un processo che dalle città si estende alla dimensione planetaria a causa delle tecnologie che hanno trasformato il mondo in un villaggio globale. Dopo aver messo a fuoco le componenti storiche, economiche politiche e sociali che determin…
Una piazza per il Belìce. Strategie per il Territorio Arcipelago
2019
Le grandi città globali non sono più gli unici contesti per la competizione territoriale: l’Italia è un importante esempio di un nuovo sistema di piccole e medie città, una sorta di arcipelago di spazi tenuti insieme da identità locali, animato dalle comunità, ma frenati da geografie impervie. L’articolo definisce come un territorio può applicare protocolli e azioni innovativi per la sfida dell’Italia interna. Questa “Inner Italy” può essere una piattaforma per l’innovazione locale, lo sviluppo sostenibile, la resilienza ecologica e sociale e la coesione territoriale, come mostrato nella letteratura internazionale, in riferimento sia al Territorio-Arcipelago (Carta, 2016), sia ai contesti u…
