AbstractIn 2015, a case of canine rabies in Arequipa, Peru indicated the re-emergence of rabies virus in the city. Despite mass dog vaccination campaigns across the city and reactive ring vaccination and other control activities around positive cases (e.g. elimination of unowned dogs), the outbreak has spread. Here we explore how the urban landscape of Arequipa affects the movement patterns of free-roaming dogs, the main reservoirs of the rabies virus in the area. We tracked 23 free-roaming dogs using Global Positioning System (GPS) collars. We analyzed the spatio-temporal GPS data using the time- local convex hull method. Dog movement patterns varied across local environments. We found that water channels, an urban feature of Arequipa that are dry most of the year, promote movement. Dogs that used the water channels move further, faster and more directionally than dogs that do not. Our findings suggest that water channels can be used by dogs as ‘highways’ to transverse the city and have the potential to spread disease far beyond the radius of control practices. Control efforts should focus on a robust vaccination campaign attuned to the geography of the city, and not limited to small-scale rings surrounding cases.

The urban landscape assesment as an important element in the quality of life and the sustainable development of the city constitutes an incipient field of investigation from a new perspective that adds meanings and values. An analysis of the different methodological developments and national and international experiences in the assessment of these landscapes will highlight its importance as a strategic element to improve the quality of the city. It starts from the concept of assessment as a system where tangible and intangible values ​​are considered by the population and the experts. These include among other formal, economic, environmental, social, cultural issues (…) and the relationships between them. Consideration of the opinions of experts from different points of view such as urbanism and architecture but also environment, economy, geography, history, archeology, sociology, social assistance, etc. Together with the preferences expressed by the population regarding the spaces they inhabit on a daily basis and their aspirations, strengthen the sense of belonging and the identity of the place as key elements in the perception of the urban landscapes that allows to contribute new qualities, integration criteria and ​​contemporary values to any type of intervention. These are strategies and intervention procedures that start from the complexity of the city as a system and incorporate the perception that citizens have or will have of their immediate environment.  References: Czynska Klara and Pawel Rubinowicz (2015). ´Visual protection Surface method: Cityscape values in context of tall buildings´.

This research proposes to identify the factors of the urban landscapes degradation in Hergla’s city (Tunisia) according on the citizen participation. It is based on the survey method which is developed around two axes: the citizen perception of urban landscapes and the factors of their degradation. According to the responses obtained, "the sea" represents the particular value of the landscapes identified as "quality" in Hergla. Citizens don’t appreciate landscapes of urban sprawl which makes the city lose its identity. Moreover, the lack of citizen participation in the urban actions and the non-observance of the urban regulations are the most cited factors of the landscape degradation. These results highlight the importance of involving the citizens in the planning process for a sustainable territory.

The purpose of this article is to consider the peculiarities of the reflection of the city – its architecture and inhabitants – in the works of Chernivtsi artists of the 20th and early 21st century, to analyze the differences between their views on the reproduction of urban motifs. The methodology consists in the application of the historical-chronological method, art analysis, and generalization, comparative and systematic approach. The scientific novelty lies in the introduction into scientific circulation of works by artists of the specified time, in understanding the evolution in the reflection of the city in the works of authors with various artistic orientations. Conclusions. In the paintings and graphics of the 20th – 21st centuries, several options for solving urban landscapes can be defined, among which the most common is a careful reflection of existing architectural monuments. In the 19th century in European art, in particular in Impressionist painting, the desire to convey not only the appearance but above all the spirit of the city became noticeable, depicting the townspeople, emphasizing the bustle or poetry of squares and streets. At the turn of the 20th-21st centuries the artists are no longer limited to the usual fixation of what is seen, but try to create a conceptual image of the city, to tell a story through iconic images and symbols, reveal their own position in particular and to preserve the authenticity of an object or the city in general. Such a variety of approaches for creating an urban landscape is partly due to differences in preferences formed during studies in art institutions and is also characteristic for the art of Chernivtsi – a city where people of many nationalities with different cultural traditions have lived side by side for centuries. Ultimately, the artists who worked here in the 20th century were often graduates not only of Ukrainian schools or universities, but also of well-known European institutions, including Vienna, Munich, Florentine, Berlin, Kraków, or Bucharest academies. While in the second half of the 19th – early 20th century the city often appears as the sum of certain architectural structures in the works of artists of Bukovina and visiting masters (F. Emery, R. Bernt, J. Shubirs), in the second half of the 19th – first third of the 20th century the artists mostly try to recreate the dynamics of urban life instead, sometimes depicted with a touch of irony, using the grotesque in the image of the inhabitants (lithography and watercolors by F.-K. Knapp, O. Laske and G. Löwendal). Subsequently, we meet emphasized mood images, in which the author's subjective perception of a particular motive, which he seeks to reproduce in a work full of emotions, is important (L. Kopelman, G. Gorbaty). A peculiar historical retrospection is present in the exquisite graphics of O. Kryvoruchko and in the distilled-finished sheets of O. Lyubkivsky, and the lyrical watercolors and sketches of N. Yarmolchuk represent the non-festive side of the city center. In O. Litvinov's paintings Chernivtsi surprises with desolation and restraint, and in M. Rybachuk's paintings it is distinguished by an unexpected riot of colors. Therefore, each of the artists creates his own image of Chernivtsi, which landscapes often become only a stimulus for the author's imagination, allowing him to depict a completely individual sense of space and life of the city.

The concept of Continuous Productive Urban Landscapes (CPUL) was introduced by Andrè Vilijoen and Katrin Bohn in 2004. This thesis project tests the application of the CPUL concept to Toronto, a densely developed North America winter city. It examines: 1. The challenges, limitations and opportunities of an existing high-rise city fabric as a platform for creating new coherent, continuous and active pedestrianized landscapes by reclaiming unused and under-utilized spaces. 2. The implications of merging reclaimed spaces with existing circulation arteries and infrastructure, to improve, invigorate and strengthen connections in the city. Through an iterative research and design exercise, which discovered many hidden potentials within the CPUL framework, this project is able to demonstrate how a linear park system is capable of seamlessly reconnecting a severed Toronto’s waterfront to the dense downtown core. Such projects can substantially benefit community life, and offer new and meaningful forms of urban connectivity that are sustainable and productive.

Abstract. Cuenca in Ecuador is a growing city, weak in the face of the changes that the expansion phenomenon implies. The area of El Ejido was the first expansion area of the city with valuable samples of the arrival of modernity in the city. Nowadays, this sector is not exempted from the effects of urban growth and deserves to be managed through a proper management plan for its preservation. Degraded landscapes have been identified, modern heritage architecture shows clear symptoms of abandonment and low maintenance, causing the disappearance of historic buildings. Given these and other problems associated with urban development, Cuenca, like other cities, has taken the initiative of adopting the Recommendation on the Historic Urban Landscape (HUL) adopted by UNESCO in 2011, as a measure to safeguard urban heritage. In 2014, the implementation of this relatively new approach was first initiated in the pilot area of the Historic City Centre of Cuenca. This area was included in the World Heritage List in 1999 based on criteria II, IV, and V.However, aware of the significant heritage values embedded at El Ejido and its close urban and landscape link with the Historical City Center, the aim of this research is the implementation of the HUL’s approach in a specific area located in El Ejido. Due to the clear difference between this sector and the Historical City Center, it is necessary to assess the first methodology used and work on a methodology that can be extrapolated to this sector and further on to other sectors of the city. To obtain the methodology for this area, it is essential to carry out a territorial exploration in cities with similar characteristics to Cuenca that are implementing an approach based on the study of the Historical Urban Landscape Recommendation.

The image of many cities in today's world has been influenced by the growing globalization along with rapidly developing demographic, technological, and economic movements. From the perspective of the last two decades, the increased high-rise development in the world is clearly visible. In recent years, modern high-rise buildings have impacted the city landscape and have become a major issue in terms of the landscape protection of a city like Istanbul with a historical peninsula silhouette. In this study, which discusses the aesthetics of the man-made environment, various factors have been evaluated by the users based on the formal aesthetic dimension in the 4th Levent area, where high-rise buildings are dense. In this context, this study aims to determine the factors that increase preferences in urban landscapes, user preferences, and the attitudes of different social groups towards the place. The main method of the study, which is based on visual landscape assessment techniques, is the visual survey technique which is administered with visuals and which is used for determining the user's perception of the place. 95 individuals participating in the survey were asked to evaluate formal aesthetic parameters for 15 selected high-rise buildings. One-way ANOVA, correlation and regression tests were employed to analyze the data collected through the survey. The findings and conclusions are thought to provide significant resources to city stakeholders in future urban landscape studies.

The COVID-19 pandemic, with its lockdowns and mobility restrictions, has created an atmosphere of global reflection towards contemporary urban landscapes. Architecture is an essential component in them and determines, to a large extent, how building users perceive, interpret, and value the surrounding environment. From an experiential and phenomenological perspective, and taking into account the situations lived in 2020, the paper invites to examine the existing relations between architecture and urban landscape at three levels: first, the experience of the environment from the architectural space —namely, the home—; second, the experience of the “interior urban landscape” at street level; and finally, the experience of the “exterior urban landscape” from the city fringe or vantage points that provide vast prospects. The article advocates a holistic understanding of landscapes from the architectural and planning practice and proposes this integrating issue as the guiding axis of new urban policies.

Данная статья посвящена исследованию отражения образных характеристик архитектурной среды города в пейзажах художников. Анализируя индивидуальные образные интерпретации разных художников, авторы предпринимают попытку обозначить общие тенденции в отображении архитектурной составляющей городского текста в целом и в частности его отдельных элементов (архитектурных объектов и пространств) в изобразительном искусстве. При этом авторами актуализируется внимание на специфике отображения различных типов городских пространств как публичных, так и камерных. При анализе публичных пространств центральной части города, формирующих «парадный портрет города», основное внимание уделяется отражению образов так называемых «визитных карточек»: наиболее значимых в семиотическом отношении архитектурных объектов и пространств, формирующих позитивный и презентабельный образ города. Некоторые фрагменты городского пространства выступают излюбленными мотивами городских пейзажей, написанных омскими художниками. Именно эти пространства воспринимаются жителями в качестве визитных карточек города и представляют собой наиболее значимые в семиотическом отношении фрагменты городского текста. В Омске, несомненно, к таким ключевым пространствам и объектам следует отнести архитектурные ансамбли ул. Ленина (Любинский проспект) и ул. Тарской, ансамбли Соборной и Никольской площадей, здания Драматического театра, Серафимо-Алексеевской часовни и Речного вокзала и др. Можно констатировать наличие излюбленных ракурсов при изображении архитектурных пространств центральной части Омска. Одним из таких является вид из окон Дома художников на реку Омь, мост и перспективу Любинского проспекта на противоположном берегу реки. Изображение Любинского у разных художников отличается не только выбором ракурса, а более настроением и своим отношением к данному пространству. Некоторые художники в своих работах выходят на глубокий уровень философского осмысления пространства, другие – показывают его будничным и обыденным. Камерные пейзажи, как правило, изображают фрагменты городской среды, относительно изолированные от центральных городских публичных пространств. К таким можно отнести дворы, арки и др. Камерным пространствам характерна близость, интимность. Большинство камерных пространств являются анонимными. Самым ярким примером камерного городского пространства являются дворы. Мотив строчной рядовой многоэтажной застройки, характерный для большинства городских окраин, также находит отражение в работах омских художников. У некоторых художников образ окраины передается как пустынное пространство, где высотная застройка перемежается с пустынными пространствами. Другой вариант осмысления данного образа предполагает трактовку окраины как пространства привычного, обжитого, наполненного утилитарными функциями и обустроенного людьми под свои нужды. This article aims to examine the reflection of figurative characteristics of the city’s architectural environment in artists’ landscapes. By analyzing individual figurative interpretations by different artists, the authors attempt to determine global tendencies in the reflection of the city’s architectural environment in general, and in its individual elements (architectural objects and spaces) in visual arts in particular. The authors focus attention on the specifics of the presentation of different types of urban spaces, both public and private. Analyzing public spaces of the city center, which form the “grand portrait of the city”, the authors concentrate on the reflection of the city’s landmarks—the most significant semiotic architectural objects and spaces that form a positive and presentable image of the city. Some parts of the urban space are favorite topics of urban landscapes by Omsk artists. It is these spaces that residents perceive as landmarks; they represent the most valuable, in semiotic terms, parts of the urban text. In Omsk, undoubtedly, the landmarks of the city are architectural ensembles in Lenin St. (Lyubinsky Prospect) and Tarskaya St.; ensembles of the Sobornaya and Nikolskaya Squares; the buildings of the Drama Theater, of the Seraphim-Alekseevskaya Chapel and of the River Boat Station, etc. Artists have favorite perspectives in depicting the architectural spaces of the central part of Omsk. One of them is a view from the windows of the House of Artist on the Om’ River, the bridge, and the perspective of Lubinskiy Prospect, which is on the other bank of the river. Artists show Lubinskiy Prospect in different ways: due to not only the chosen angle, but also their mood and attitude to the space they depict. Some artists go to the deep level of a philosophical understanding of the surrounding space, while others illustrate it as ordinary. Private landscapes, as usual, show parts of urban environment that are relatively isolated from public central urban spaces. Yards and arches are examples of it. Private spaces usually have a close, intimate atmosphere. Most private spaces are anonymous. The most vivid examples of the private urban space are yards. Omsk artists also reflect the motif of multistorey buildings, mainly concentrated in the outskirts, in their works. Some artists depict the outskirts as an empty space, while others interpret them as a habitual, familiar space full of utilitarian functions and arranged by people to meet their needs.

Combining multivariable statistics and geostatistics with landscape metrics, we attempted to quantify the spatial pattern of urbanization in the city of Niamey, Niger. Landscape metrics provided local quantification of both landscape composition and physiognomy while the Principal Component Analysis (PCA) yielded a multivariable summary of the main source of landscape metrics variation across the city. We used the variogram (geostatistics) to analyze the spatial pattern of the PCA outcomes and to characterize the associated spatial scales of variation. In Niamey, the main urban structure corresponded to a gradient ranging from highly diversified, fragmented, and both wooded and built-up areas in the city center and along the Niger River, to less green zones gathering steel-roofed houses whose density diminished towards the periphery. This concentric structure centered on the Niger River clearly reflected the history of Niamey. PCA and geostatistics provided appealing quantitative estimates of spatial patterns, scales, anisotropy and intensity of urban structures. Although these different tools are known in landscape ecology, they are rarely used together. The present paper illustrates how they allow characterizing the marked spatial variation of the urban landscape of the fast-growing African city of Niamey (Niger). Such a quantification of the urban landscapes may be extremely useful for future correlative investigations in various fields of research and planning.
