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.

This article investigates the relationship between urban landscapes and the challenges imposed by climate change. As a case study, the city of Copenhagen is discussed from both a normative and practical point of view. The article investigates the normative and planning process that has brought the urban landscape of Copenhagen one step closer towards a more effective interaction between natural and human factors, as outlined in the CEP. In addition, the paper also presents examples of nature-based solutions to improve adaptation to climate change, reducing the environmental risks and improving the quality of life. A positive aspect of the city planning process is that climate change provides a framework for all projects and is a primary driver of urban regeneration.

En ciudades con un importante patrimonio histórico son cada vez más frecuentes los procesos de homogeneización del paisaje urbano. Una dinámica que conduce a la transformación de determinados entornos históricos en espacios en donde apenas queda lugar para la singularidad, las actividades no reguladas o la participación ciudadana. Este estudio propone analizar una serie de iniciativas desarrolladas en la última década en centros de cuatro ciudades españolas, concretamente en Sevilla, Barcelona, Madrid y Zaragoza. Proyectos que se apoyan en la agricultura y la jardinería urbanas para sortear la banalización imperante, creando espacios para la cultura, las relaciones sociales y la imaginación. Pese a las dificultades en su gestión y su repercusión minoritaria, estas intervenciones ejemplifican un modo de reconfigurar el paisaje urbano, planteando esquemas de activación, percepción activa y participación en lugares centrales de la ciudad en proceso de abandono, donde las actividades agrícolas y jardineras adquieren un peso importante.PALABRAS CLAVE: paisaje urbano, acupuntura urbana, agricultura urbana, participación ciudadana, derecho a la ciudad.Processes of homogenization of the urban landscape are becoming more frequent in cities with an important historical heritage.

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´.

‘Text’ has been a frequent notion in analytical conceptualizations of landscape and the city. It is mostly found in analyses of textual representations or suggestions concerning a metaphor of “reading” an (urban) landscape. In the Tartu- Moscow School of Semiotics the idea of the text of St. Petersburg has also been applied in analysing particular cities as organizing topics in literature and in culture more widely, but it has not happened to an equal degree in studies of actual urban spaces. The understanding of text as a semiotic system and mechanism is, however, more promising than revealed by these conceptions. Some potential can be made apparent by relating this textual paradigm to a more pragmatic understanding of the city and its planning. My project in this paper is to uncover an analytical framework focusing on the concepts of ‘text’, ‘textualization’ and ‘texting’ in studying the planning of urban environment. The paper observes the case of the urban planning process of the Tartu city centre in Estonia during 2010–2016, and is particularly concerned with the roles that urban nature has acquired in the process of this “textualization” of the local environment, societal ideals, practices and possible others.

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.

The accelerated urban growth of the last decades in Europe has caused, especially in the Spanish Mediterranean coast, a paradigm shift in much cities, moving from a mostly compact urban form to a more diffuse one. The concept of city has changed so much that even in a lot of dispersed municipalities, it becomes difficult to define its limits. This change implies not only ecological and economic impacts, but also, social effects. Urban sprawl makes difficult social interaction and reduces the community feeling, and therefore, social cohesion and identity. This produces also changes in the relations of citizens between them and with the city council. The research propounds a discussion about the challenges that the urban sprawl causes for the application of participative models in the decision making, understanding them as basic criterion of good government. We analyze a case study to extract the complexity of articulating processes of citizen participation in territory with high dispersion based on a project carried out in the municipality of La Pobla de Vallbona (Valencia) on participatory budgets. It analyzes the results of the process carried out in relation to the urban model, the morphology of their urban pieces and spatial structure, and the demographic and social characteristics of the municipality. The question is identifying the problematic for the articulation of participative processes in territories with this idiosyncrasy. Finally, the article suggests a series of strategic lines as starting points to achieve participatory processes in the city characterized by urban sprawl.

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.

<p><strong>Abstract.</strong> The cities have developed over time responding to various urban dynamics, in this process have been configured representative images, product of the synergy created between the natural elements of the environment and those built by the communities. The analysis of visuals, materializes a landscape value, not evidenced at the time of planning and design projects for cities with value surroundings; you can take as an example those good practices that other countries have implemented to assess, preserve and protect views such as English Heritage (2011), London View Management Framework (2012) or View Protection Guidelines of the city of Vancouver (2011). The methodological analyzes the view in two stages: the first one strategic points of observation and view basins are identified and described as element integrators &amp;ndash; what is seen, and through citizen participation accepts or does not accept the evaluation criteria; in the second, the view is evaluated through the relationship between quality and incidence, giving it an assessment of how fragile it is. The application of the methodology in the area known as El Ejido in the city of Cuenca &amp;ndash; Ecuador, has resulted in a total of twentyeight visuals considered relevant. Nine of them, have been analyzed completely, evidencing that there is a view quality very High / High; nevertheless, they are affected by urban actions that generate that the incidence is High and therefore the fragility and vulnerability is greater.</p>
