Climate change affects, directly and indirectly, the tangible and intangible features of heritage sites. Conservation studies often examine the impacts of climate change on heritage sites by assuming it as an isolated and static concept. This study aims to debate cultural heritage concept as the primary and neglected factor for wise development of climate-resilience policies. We first adopt the qualitative Meta-synthesis method to analyze the impacts of climate change on world heritage sites, through a systematic review of reports published by the UNESCO and its advisory bodies. Then, it is explained why the sustainability of cultural heritage requires a fundamental reconsideration of the concept and promotion of its evaluation framework. The findings suggest that protection of cultural heritage and developing the climate-resilience policies for the sustainability of landscape requires at the early stages a reflection on how heritage is defined as a useful resource and acceptable characteristic of territory.
Climate change has dramatically affected the rainfall patterns and water systems in Central Italy. The vulnerability of this area to climate change and natural hazards necessitates that appropriate adaptation policies be put in place to protect heritage sites. This study aims to develop a cultural and natural heritage conservation framework for Central Italy that enhances the capacity of climate change adaptation for heritage resources. For this purpose, a comparison was made between the UNESCO (United National Educational, Scientific and Cultural Organization) Convention of 1972 and the European Landscape Convention of the Council of Europe to achieve a coherent vision for the protection of heritage resources in Europe. After describing the impacts of climate change on heritage resources in Central Italy, we analyze and suggest improvements to the conservation framework for wisely protecting heritage resources in a changing climate. The findings reveal that conservation sectors require assessments of the value of heritage resources at the territorial scale to effectively define conservation priorities, assess the vulnerabilities, and more precisely direct funding. In this respect, the integration of the European Landscape Convention with territorial planning may boost the unity of a conservation framework in terms of climate change while providing new opportunities for conservation authorities to develop adaptation policies.
The COVID-19 pandemic is changing people’s habits and behaviors and will reshape city layout and management. Among the different areas of research to be explored, the paper outlines first inputs to use the COVID-19 health crisis as a “window of opportunity” to trigger a sustainable transition of urban living environments, through actions to reshape and territorial organization after COVID-19 and in preparation for future health. Before having a vaccine or medications that ensure a non-lethal disease course, there will be a phase of responsibility and coexistence with the virus. It will be a period whose duration experts are still unable to quantify. What changes in the city organization, behaviors and uses of spaces will we observe in the living environments? Will this lead to a sustainability transition? The paper proposes a qualitative review to investigate how the droplet might travel through the air and how COVID-19 has spread in different urban contexts to outline a comprehensive reflection on the future of the city and strategies for more resilient communities and territories. To achieve this goal, the paper proposes the need of a comparison between skills related to physics aspects, such as fluid dynamics (to assess how droplets spread) and skills related to architectural, urban and territorial design (to evaluate the conditions of indoor and outdoor living environments).
The aim of this paper is to identify a parameterization method that considers existing connections and relationships between traditional indicators of environmental sustainability as a step in combating climate change via urban strategies. A typical Mediterranean city (Ancona, Italy) is investigated with a multi-objective optimization platform called modeFrontier, which uses Pareto optimality. This concept formalizes the trade-off between a given set of mutually contradicting objectives, such as high thermal comfort and low energy consumption, to identify a set of Pareto solutions. A solution is Pareto optimal when it is not possible to improve one objective without deteriorating at least one of the others. The optimization process employs given constraints (for example, meteorological scenarios with high temperature and low winds or morphological building parameters), custom procedural algorithms (recursive algorithms to generate the set of all non-dominated objective parameters), and genetic algorithms (inspired by the natural selection process) to examine a wide urban space and identify interesting relationships among relevant variables for typical summer scenarios. Multi-objective optimizers involve many evaluations of two objectives (i.e., energy consumption and thermal comfort in this study) while considering many analytical constraints. This approach entails a considerably more exhaustive search of environmental variables that can help the urban planning process to mitigate the urban heat island (UHI) effect. Three quantitative metrics related to urban morphology and local climate conditions, as well as a thermal comfort indicator (the predicted mean vote), are defined and applied to Ancona to examine the potential for new sustainability in urban design. The results show that two parameters examined-compacity and a building-scale energy indicator-can offer insight when designing comfortable cities, while a citywide energy indicator shows that it is more difficult to find optimal solutions when dealing with the city as a whole. The research serves as a proof-of-concept and the possibility of identifying some local strategies in order to combat the UHI is verified.
