Assessing Flexible Places for Adaptive Urban Design:A New Method and the Case of Cittaducale

Each place has its own peculiarities,determining that the resilience and adaptation to diverse types of risks will be different,requiring different time and methods for mitigation as well.The coexistence of several risks determines further resolution difficulties as commonly,since risks are sudden and unforeseen,there is a tendency to treat the last risk more carefully,neglecting the previous one even if it is just as important.Most of the methodologies used to analyse areas affected by different risks are aimed at focusing in particular on seismic risks without considering those relating to intangible aspects linked to the identity of the places or aspects related to urban health and liveability.And,more in general,in relation to design aspects,urban methodologies do not consider all the results of the analyses,maybe for the difficulty deriving from translating the complexity of collected data in project interventions.Starting from these premises,the objective of the article,elaborated within the SISMI and PRIN 2020 research projects is to propose an original methodology capable of analysing the places affected by multiple risks and planning its resilience attentive to its cultural resources and to its liveability.To this end,the proposed method will be aimed at creating flexible and adaptive places and the case-study of Cittaducale will be illustrated.Criticalities and qualities of this place affected by an earthquake in 2016 will be reported and project interventions to transform its risks into opportunities will be shown.

Urbanization has opposite effects on the territory size of two passerine birds

Background:Urban expansion has been identified as one of the leading drivers of biodiversity change or loss.For birds,urbanization is specifically related to survival,breeding success,and territory size.Understanding how different birds adjust territory size in response to urbanization is essential for their conservation in urban environments and to better understand why some species are lost and others persist under this condition.We evaluated the effect of urbanization on the territory size of an urban avoider species,White-eared Ground-Sparrow(Melozone leucotis),and an urban adapter species,House Wren(Troglodytes aedon),at five Costa Rican sites.Methods:We measured the size of 30 ground-sparrow and 28 wren territories using a total of 296 h of observation.We followed each individual for at least 1 h per day for at least 2 days of two consecutive years,and geo-referenced their locations.Territory size was estimated using the minimum convex polygon method.We measured the urban surfaces(roads,buildings,any other paved area,soccer fields,lawns,and gardens with short grass)within territories.Results:Ground-sparrow territories were larger at the highly urbanized site than at the non-urbanized site.Wren territories were larger at the low urbanized site than at the highly urbanized site.We found a positive relationship between urban surface and territory size for the ground-sparrow,but not for the wren.Conclusions:Our results showed that not all birds adjust territory size in the same way in response to urbaniza-tion.We showed that urban avoiders probably need to defend larger territories in urban environments to find all the resources required to survive because urban environments may provide insufficient resources such as food or shelter.Urban adapters on the other hand defend smaller territories in urban environments because even small territories may provide sufficient resources.These results suggest specific behavioral adaptations developed by Neotropical birds inhabiting urban environments.

The urban adaptation and adaptation process of urban migrant children: A qualitative study

This article employs qualitative research methods to explore the urban adaptation and adaptation processes of Chinese migrant children.Through twenty-one in-depth interviews with migrant children,the researchers discovered:The participant migrant children showed a fairly high level of adaptation to the city;their process of urban adaptation emerged as three categories:the U-Type,the J-type,and the“flat line”type.Also explored were long-term acquisition of explicit behaviors,implicit notions,adaptation to the socio-cultural environment,and success in education as difficult aspects of adaptation.After comparing these three processes,the research team developed a theory of migrant children urban adaptation.It hypothesizes that during the urban adaptation process,migrant children will encounter four stages of development:excitement and curiosity,shock and resistance,exploration and adaptation,and finally integration and assimilation.

A new strategy for integrated urban water management in China：Sponge city

Urban water-related problems associated with rapid urbanization, including waterlogging, water pollution, the ecological degradation of water, and water shortages, have caused global concerns in recent years. In 2013, in order to mitigate increasingly severe urban water-related problems, China set forth a new strategy for integrated urban water management(IUWM) called the "Sponge City". This is the first holistic IUWM strategy implemented in a developing country that is still undergoing rapid urbanization, and holds promise for application in other developing countries. This paper aims to comprehensively summarize the sponge city. First, this paper reviews prior studies and policies on urban water management in China as important background for the sponge city proposal. Then, the connotations, goals, and features of the sponge city are summarized and discussed.Finally, the challenges, research needs, and development directions pertinent to the sponge city are discussed based on investigations and studies conducted by the authors. The sponge city in China has a short history—given this, there are many issues that should be examined with regard to the stepwise implementation of the Sponge City Programme(SCP). Accordingly, the authors perceive this study as only the beginning of abundant studies on the sponge city.
