Balancing conservation and development is one of the biggest challenges in the management of heritage cities. In 2011, UNESCO adopted the Recommendation on the Historic Urban Landscape in order to ...guide conservationists, urban planners and city administrations in this difficult process. Based on an interpretative policy analysis, this paper explores the implementation of the Historic Urban Landscape approach in the Uzbek World Heritage city Khiva. It describes recent development trends in the city's historic centre related to urban form, tourism and heritage management. These observations are then checked against the recommended 'critical steps' and tools from the Historic Urban Landscape Recommendation. The paper explores if recent urban developments in the city reflect a new understanding of the historic urban landscape, and to what extent the implementation of the Historic Urban Landscape approach supports the reconciliation of conservation and development in the urban regeneration of the city. The analysis shows that while some of the Recommendation's principles have been implemented, others are barely respected. Conflicts between the interest of tourism development, heritage conservation and the needs of local residents are ubiquitous and represent a case of heritage dissonance.

Urban landscape (UL) management and urban greenspace (UG) delivery require effective planning tools. The aim of the study is to develop a conceptual framework for the implementation of ecological, ...structural and visual landscape and greenspace indicators (LGI) in spatial development of urban areas. The UL and UG management provisions in Poland are identified at various levels of urban planning (local, municipal and regional). Furthermore, the applicability of the selected set of LGI in the Polish planning system is considered based on the existing planning documents. The quality of UL and UG transformation is discussed in three case studies in Bristol, Gdańsk and Poznań in the broader context of the English and Polish spatial planning systems. Bristol is used as a point of reference for the evaluation of UL and UG management in Poland and for the comparison between English and Polish landscape policies. Based on the conceptual framework and the analysis of the case studies, critical areas of UL and UG management in Poland are identified. The existing planning system often fails to ensure the continuity of landscape structures, and it does not include its preservation and enhancement to a sufficient extent. Therefore, the implementation of the proposed LGI framework could significantly improve the ecological and visual quality, as well as the structural diversity of UL and UG. Moreover, the article concludes by indicating some practical implications of the proposed LGI framework for urban planners, policy makers and other stakeholders in terms of improving the modes of governance for UL and UG management as well as of accounting for human health and well-being.
The aim of the article is to understand to what extent modern mass housing estates, built in the decades following the Second World War with new construction methods and under the influence of ...innovative planning ideas and egalitarian philosophy, are currently facing a process of decline. In particular, the research is committed to understand how such innovative urban structures rapidly evolved into stigmatized places of residence and sources of dissonant heritage. The work focuses on the case of San Polo, a neighbourhood of Brescia, in Italy, designed by architect, planner and historian Leonardo Benevolo, who had the opportunity in the northern Italian city to experiment and implement his architectural views in the sphere of “public urbanization”. It is possible to claim that Benevolo’s theoretical approach and architectural practice excellently represented the golden age of modern housing in postwar Europe, when the connection between progressive political views and egalitarian urban planning was apparently perfect. Nevertheless, after the political and economic transition that characterized western Europe since the 1980s, mass housing quickly became a residual issue in the public discourse and entered in a spiral of decline. San Polo was no exception: problems – especially in its iconic tower blocks – soon emerged, and overall optimistic expectations were frustrated by the reality of physical, social and economic decline. This study is therefore committed to understand to what extent San Polo is a case of dissonant heritage in the urban context. While it is clear that the heritage of San Polo is the heritage of a precise historical phase and represents particular ideas in architecture and planning, on the other hand it must be stressed that the ideological transition of recent decades made its values and its messages obsolete and that socio-economic segregation negatively affected the reputation of the neighbourhood and its inhabitants had to face a process of stigmatization that found echo in official and journalistic discourse.
Typomorphological analysis has been used to study building types, but it is seldom applied to open spaces. This paper argues that the same systematic and rigorous approach can be applied to define ...public open spaces. It explores the potential of the application of a systematic analysis of types and forms to define urban landscapes. Drawing on existing literature, this paper identifies specific attributes related to urban landscape elements including formal and spatial aspects. This paper highlights the potential of open space networks to respond to the contemporary challenges facing urban designers working to create better places to live in. This paper contributes to the field of design research through the development of a method of survey and analysis to inform design decision-making processes. Its significance lies in proposing a comprehensive framework to contribute to a more detailed definition of urban landscape character and inform the development of sustainable urban strategies.

The historic urban landscape (HUL) is the result of the continuous dynamic process of production, interaction, and accumulation. It is full of information from bygone years and remains to this day as ...a living witness of antiquity and a benefit to the contemporary public, both in mind and spirit. These intangible benefits, however, are easier to overlook than the tangible ones in conservation and management efforts that aim at sustainability. Therefore, we return to the prototype of the category “cultural services” in the ecosystem classification “information service” to evaluate these intangible benefits. The objectives of this study are: (1) to provide a methodological framework to assess the ability of the landscape to continuously provide information services in the historical process; (2) to analyze the drivers affecting HUL’s ability to continuously deliver information services, and then discuss the governance experience of HUL’s intangible dimensions for sustainability. First, we regard HUL as an object to learn from the experience of urban heritage governance: using the methods and tools of ecosystem service evaluation, this paper evaluates the intangible services that the public receives from the landscape over several consecutive historical periods, summarizes the dynamic changes in these services, and analyzes their drivers. Furthermore, we consider that the aforementioned intangible services are brought about in part by the spread of heritage information stored in HUL among specific people, and the continuous provision of information services is considered the sustainability of HUL in intangible dimensions. We use Yuexiu Hill in the center of Guangzhou, China, as a case study to verify the feasibility of our methodological framework by evaluating the information services provided by this ancient area with a construction history of 2000 years over five historical periods. The data needed for the evaluation of the information service was obtained through text mining by retrieving 1063 ancient Chinese poems related to Yuexiu Hill from the poetry database. The results obtained through this evaluation framework will provide a quantitative basis for planning, design, and decision making in small and medium-sized landscapes.
Urban heritage conservation in China has been subject to severe criticism, although there is now a sense of paradigm shift. Charters, declarations and agendas had the merit of filtering down the ...international discourse on heritage, while more innovative approaches were arising. The UNESCO Historic Urban Landscape recommendation, offers a new angle from which to observe this process of change. The underlying argument of this article is that HUL can provide a platform to achieve greater sustainability in transforming historic sites in China, particularly in rural areas, overcoming, at the same time, the easy shortcut of the East-West discourse of difference in respect to heritage conservation. This is primarily due to the shifting focus from the materiality of heritage to its role in sustainable development with increasing attention on the role played by local communities. By presenting the proposal for the protection of the historic rural village of Shuang Wan in the Jiangsu Province, this paper aims to reflect on this shift showing its advantages but also some of the risks. These are inherent in a discourse of heritage in danger of legitimising mere pro-growth development approaches, if not accompanied by participatory practices considerate of the specific social reality of China.

This article demonstrates how and when the nation—whether in the shape of concrete national symbols or as an frame of reference—became relevant to ordinary people. It focuses on the experiences and ...activities of Amsterdam citizens in the second half of the 19th century. Central to the analysis is the apparent contradiction between ‘banal’ or ‘everyday nationalism’, in which nationalist symbols and rhetoric appeared to successfully reach their audience because of their omnipresence in daily life, and ‘national indifference’, as referring to the absence of national identification among the masses. It argues that in order to overcome the dichotomies between elites and masses and national and non‐national performances, we should focus on the popular incentives for national identification, rather than on the ideological content and the (physical or symbolic) borders of the national community.

Measuring the amount of vegetation in a given area on a large scale has long been accomplished using satellite and aerial imaging systems. These methods have been very reliable in measuring ...vegetation coverage accurately at the top of the canopy, but their capabilities are limited when it comes to identifying green vegetation located beneath the canopy cover. Measuring the amount of urban and suburban vegetation along a street network that is partially beneath the canopy has recently been introduced with the use of Google Street View (GSV) images, made accessible by the Google Street View Image API. Analyzing green vegetation through the use of GSV images can provide a comprehensive representation of the amount of green vegetation found within geographical regions of higher population density, and it facilitates an analysis performed at the street-level. In this paper we propose a fine-tuned color based image filtering and segmentation technique and we use it to define and map an urban green environment index. We deployed this image processing method and, using GSV images as a high-resolution GIS data source, we computed and mapped the green index of Milwaukee County, a 3,082
urban/suburban county in Wisconsin. This approach generates a high-resolution street-level vegetation estimate that may prove valuable in urban planning and management, as well as for researchers investigating the correlation between environmental factors and human health outcomes.
It is well known that extremely hot weather causes heat-related health issues. Health problems, especially in urban areas, are becoming increasingly important due to urban heat island effect. ...Understanding the impact of neighborhood characteristics is important for research into the relationship between thermal environment and human health. The objectives of this study were to explore the urban landscape and sociodemographic characteristics affecting heat-related health and identify spatial inequalities for vulnerable groups. A total of 27,807 heat-related EMS incidents were used at the census block group level (N = 285). We used land cover database and Landsat satellite images for urban landscape variables and used 2019 U.S. Census data for sociodemographic variables. Negative binomial regression was used to identify the neighborhood variables associated with the heat-related EMS incidents in each block group. Heat-related health has been alleviated in block groups with high green areas. However, the negative effects of thermal environments on human health were higher in areas with a high percentage of impervious surface, over 65 years, non-white people, no high school diploma, or unemployment. The results indicate that heat-related health problems can be addressed through prevention strategies for block group variables. Local intervention efforts to solve health issues should be targeted at more vulnerable areas and groups.
•Most of the country-scale AFIS were good indicators of old forest at the city-scale.•AFIS may be a useful indicator of landscape and land-use structure transformation.•We confirmed AFIS ...applicability in urban conditions in a wider ecological context.•AFIS are good indicators of high conservation value forests in cities.
We aimed to assess the impact of land-use structure on AFIS occurrence and evaluation of these bioindicators in urban conditions. We compiled data about forest continuity based on archival maps and forest management plans; floristic records of 79 AFIS occurrences were collected within a 1×1km grid and land-use form structure in Poznań (W Poland). We tested fidelity of AFIS using χ2 tests and effects of land-use structure using random forest models. We also checked spatial autocorrelation and its impact on AFIS distribution patterns within old and recent forests, using spatially explicit generalized linear models. We found a strong relationship between AFIS number per grid square and fraction of forests and waters in land-use structure. Relationships between AFIS distribution and land-use shows that AFIS are a good proxy describing human impact or an urbanity gradient. AFIS number per grid square shows small, but significant positive spatial autocorrelation, which suggests possibilities of migration into new forests. AFIS, treated as a bioindicative group of species, may be a useful indicator of landscape and land-use structure transformation in urban environments. Occurrence of many AFIS that are endangered at the city scale indicates the need for conservation of old forests in urban areas, to preserve biodiversity in urban environments. Thus, AFIS may act as indicators of old forests with high conservation value in cities, which need special protection.
