Even though soil temperature in urban environment influences a range of processes, it has been studied rather sparsely in comparison with surface temperature or air temperature. Our research extends the soil temperature observation in Olomouc (Czechia) and uses semi-stationary measurement to describe detailed spatial variability of soil temperature in the area of a medium-sized Central European city. Differences in soil temperature 20 cm below grass-covered surface may exceed 3°C due to soil type, shadow cast by buildings and grass characteristics, which means that the representativeness of the data on soil temperature from a meteorological station within a city may be limited. Further research and a conceptual approach towards the study of soil temperature in urban landscape is needed.

AbstractUsing data obtained by soil temperature measurement at stations in the Metropolitan Station Network in Olomouc, extensive semi-stationary measurement was implemented to study the spatial variability of the soil temperature. With the development of the research and computer technology, the study of the temperature is not limited by the complexity of the processes determining the soil temperature, but by the lack of spatial data. This study presents simple semi-stationary soil temperature measurement methods, which can contribute to the study of the spatial variability of soil temperature. By semi-stationary measurement, it is possible to determine the average soil temperature with high accuracy and the minimum soil temperature with sufficient accuracy at a depth of 20 cm. It was proven that the spatial variability of the minimum soil temperature under grass at a depth of 20 cm can reach up to several degrees Celsius at the regional level, more than 1°C at the local level, and tenths of °C at the sublocal level. Consequently, the standard stationary measurement of the soil temperature can be regarded as representative only for a very limited area. Semi-stationary soil temperature measurement is, therefore, an important tool for further development of soil temperature research.

The City

As destination of choice for many short-term study abroad programs, Berlin offers students of German language, culture and history a number of sites richly layered with significance. The complexities of these sites and the competing narratives that surround them are difficult for students to grasp in a condensed period of time. Using approaches from the spatial humanities, this article offers a case study for enhancing student learning through the creation of digital maps and itineraries in a campus-based course for subsequent use during a three-week program in Berlin. In particular, the concept of deep mapping is discussed as a means of augmenting understanding of the city and its history from a narrative across time to a narrative across the physical space of the city. As itineraries, these course-based projects were replicated on site. In moving from the digital environment to the urban landscape, this article concludes by noting meanings uncovered and narratives formed as we moved through the physical space of the city.

Abstract In Europe, the debate on the recovery of the historic centres has been developed, over the years, around the balance between conservation and transformation needs in order to meet the new demands of the contemporary world. In the field of urban planning, the strictly conservative and binding approach has gradually been supported by flexible and consensual mechanisms that act as a stimulus to private initiative in the redevelopment and regeneration of the historic urban landscape. The consolidated Italian experience in the policies for the protection and enhancement of historical settlements is being significantly innovated after the entry into force of the Urbani Code, which extends the character of landscape heritage to the historic urban fabric, transferring to the regional authorities the task of establishing the specific regulations for its use and transformation. The Region of Sardinia has achieved an important role in the implementation of policies for the recovery and redevelopment of the historic centres identified by the Regional Landscape Plan (RLP). The common and consolidated practice is still characterized by the use of traditional regulative instruments, in particular the detailed plan, which provide rules for the requalification of the compromised urban fabrics through a set of rules and guidelines to be applied to the replacement of recent buildings and the renovation of urban patterns that for density, ratios between solids and voids, heights, alignments and elevations are incompatible with the values of the context. The constraint and binding approach is effective in the conservation strategies but often inadequate to implement actions of integrated redevelopment of urban fabric altered by new buildings in contrast with the historic urban landscape features, also due to the global crisis situation and the shortage of public funding. The paper proposes the use of the non-financial compensation tool, based on the granting of bonus development rights to realising on site or in alternative locations, in order to encourage urban regeneration projects that also involve the replacement of buildings incompatible with historical urban landscape morphological patterns. The integration of a methodology for assessing the financial feasibility of the demolition and reconstruction of the incompatible structures in the planning process, as tested in the case study of Villasor municipality, has allowed the elaboration of a model to support the use of a compensation mechanism for the redevelopment of historical settlement values. In this perspective, the paper aims to investigate the opportunities provided by market-oriented and flexible approaches to support and promote private urban regeneration projects. In particular, it illustrates the experimental results of a methodology for the analysis of the urban fabric that takes into account the factors influencing the feasibility of the intervention of demolition and reconstruction of the incompatible buildings. Finally a model for the assessment of any bonus in terms of additional building capacity is suggested, to be granted to private operators as an incentive to ensure the cost-effectiveness of the project.

Historic allées and urban avenues reflect a far-sighted and forward-thinking design attitude. These compositions are the living witnesses of olden times, suggesting permanence. However, the 20th century’s urban development severely damaged the environment, therefore hundred-year-old mature trees are relatively rare among city avenues’ stands. Due to the deteriorated habitat conditions, replantation may be necessary from time to time. However, there are a large number of replanted allées and urban avenues considered historical monuments, according to the relevant international literature in urban and living heritage’s preservation. The renewal often results in planting a different, urban tolerant taxon, as seen in several examples reviewed. Nevertheless, the allée remains an essential urban structural element, though often with a changed character. The Budapest Andrássy Avenue, a city and nature connection defined in the late 19th century’s urban landscape planning, aimed to offer a splendid link between city core and nature in Városliget Public Park. The 19–20th century’s history and urban development are well documented in Hungarian and several English publications, though current tree stock stand and linear urban green infrastructure as part of the urban landscape need a detailed survey. The site analyses ran in 2020–early 2021 created a basis for assessing the allées and the whole avenue as an urban ecosystem and a valuable case study of contemporary heritage protection problems. Andrassy Avenue, the unique urban fabric, architecture, and promenades have been a world heritage monument of cultural value since 2002. The allées became endangered despite reconstruction type maintenance efforts. The presented survey analyses the living heritage’s former renewal programs and underlines the necessity of new reconstruction concepts in urban heritage protection. We hypothesize that urban green infrastructure development, the main issue in the 21st century to improve the urban ecological system and human liveability, may support heritage protection. The Budapest World Heritage Site is worthwhile for a complex renewal where the urban green ecosystem supply and liveable, pedestrian-friendly urban open space system are at the forefront to recall the once glorious, socially and aesthetically attractive avenue.
