Urbanization in the Middle Niger of Mali

When the tell site of Jenne-jeno was brought to light in the vast floodplain of the southern Middle Niger of Mali, archaeologists had to question certain expectations about just what constitutes an ancient city. The city was certainly too early (3rd century bce rather than the expected late first millennium ce) and Jenne-jeno did not conform to the standard city form (a mosaic of satellites rather than the expected agglomeration). But it was the persistent lack of evidence of a centralized ruler, social strata of elites, and of the hierarchical decision-making mechanisms of the state that set this urban landscape so at odds with then prevalent urban theory. The seventy apparently contemporaneous hamlets and specialists’ occupation mounds surrounding Jenne-jeno form the Jenne-jeno Urban Complex. It is a classic example of African originality in evolving urban landscapes. In place of the top-down, often despotic state control as the organizing principle of the city, here there is a classic city without citadel—and thus heterarchy (authority and power relations arrayed horizontally) instead of a social and political hierarchy at the heart of the city can be posited. The search for the pre-Jenne-jeno antecedents has taken a newer generation of archaeologists to look at “pre-urban” landscapes in other, now-dry parts of the Middle Niger deep in the northern. Sahel and Sahara. Back to the second millennium bce, the single site can be found to be the exception; clustering had roots deep in time.

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.

Athens is a historic capital widely known for its legacy left to Western civilization and its publicly recognized and well-studied monuments of world heritage. But what do we really know about the Athenian antiquities that have been integrated into the city’s modern canvas? In how many ways can the urban landscape of Athens be re-introduced to the modern traveler? Walk the Wall Athens is a bilingual mobile application that allows the user to wander, literally and metaphorically, through the streets of Athens in order to explore the traces of the Themistoclean city wall and to recover this important monument from oblivion. Just as the ancient city wall surrounds Athens as a historical chain that crosses all the neighbourhoods of the modern city’s historical centre, the route provided by the interactive map of the application introduces the visitor to the layout of the modern Athenian metropolis. Through a walk on the remains of the ancient fortification, the application Walk the Wall Athens attempts to spark the interest and excite the curiosity of the Athenian traveller of the 21st century, introducing him to a journey of 2,500 years of history.

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.

This article brings together two distinct aspects of Aldo Rossi's urban theory and reads them against recent urban peripheral development in Madrid. By exploring the scientific method used in Rossi's work The Architecture of the City against the contemporary conditions of this metropolis, the authors examine whether and to what extent either ‘memory’ or ‘permanence’ are reflected in this new city. Additionally, the analogous city of fragments that Rossi explored in the second phase of his career is also brought into play, and considered in relation to Rossi's scientific method. Developing from Rossi's later approach, we carried out a photographic survey of these areas to understand the contemporary urban landscape. We utilise these two theoretical positions in his work as a form of critique on today's periphery, focusing on two of the Urban Action Plans (PAUs) — Las Tablas and San Chinarro — in the city of Madrid, and bridging the ideas of theory and project that were so important for La Tendenza, the group of architects to which Rossi belonged in the 1960s. These specific study areas allow a broader understanding of the patterns of urban development around Madrid, and the consequences of these projects as experienced by citizens of the city. More broadly, this analysis aims to further our understanding of the European urban peripheral condition, and points to the continuing relevance offered by the theoretical approaches of Rossi's work in today's context, a critical discourse that is felt to be necessary by the authors.

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.
