Climate Mitigation and Adaptation Concerns in Urban Areas
Urban areas continue to be the center of action for many countries due to their contribution to economic development. Many urban areas, through the urbanization process, have become vulnerable to climate risk, thereby making risk mitigation and adaptation essential components in urban planning. Climate change is highly attributed to anthropogenic activities, and this makes population growth in urban areas a factor of global warming. The numerous problems and vulnerabilities associated with the urbanization process place urban areas at the center of climate adaptation and mitigation. Massive efforts have been made by urban areas and cities in general to mitigate and adapt to climate change. As reported, many of the world’s urbanized areas have agreed on protocols that address climate change and push for urban actions that reduce greenhouse gas emissions and climate risks. Urban areas and cities’ mitigation and adaptation actions to climate risks are, thus, essential towards the reduction of vulnerabilities.

Circular Economy Management of WEEE in Italy
Waste Electrical and Electronic Equipment (WEEE) management is one of the key waste value chains in the EU Circular Action Plan. Electrical and electronic devices are mainly used within urban systems as a consequence of increasing purchasing power, quality of life, and access to grid electricity. The consequent generation of WEEE requires appropriate management, based on urban collection centres and collection and recovery networks, an increase in awareness of the recoverable valuable materials, the need to prevent environmental impacts, and the potential for new jobs in the urban mining sector.

China’s New-Type Urbanisation
China’s new-type urbanisation, as a national strategy, is one of the reasons why the leap in development has been made in the last decade. Existing studies mainly focus on the status and outcomes of china’s new-type urbanisation while stressing not enough the overlooked aspects of new-type urbanisation policies that are currently in use.

Causalities of Upscaled Urban Aquaponics
Aquaponics, the water-reusing production of fish and crops, is taken as an example to investigate the consequences of upscaling a nature-based solution in a circular city. We developed an upscaled-aquaponic scenario for the German metropolis of Berlin, analysed the impacts, and studied the system dynamics. To meet the annual fish, tomato, and lettuce demand of Berlin’s 3.77 million residents would require approximately 370 aquaponic facilities covering a total area of 224 hectares and the use of different combinations of fish and crops: catfish/tomato (56%), catfish/lettuce (13%), and tilapia/tomato (31%). As a predominant effect, in terms of water, aquaponic production would save about 2.0 million m3 of water compared to the baseline. On the supply-side, we identified significant causal link chains concerning the Food-Water-Energy nexus at the aquaponic facility level as well as causal relations of a production relocation to Berlin. On the demand-side, a ‘freshwater pescatarian diet’ is discussed. The new and comprehensive findings at different system levels require further investigations on this topic. Upscaled aquaponics can produce a relevant contribution to Berlin’s sustainability and to implement it, research is needed to find suitable sites for local aquaponics in Berlin, possibly inside buildings, on urban roofscape, or in peri-urban areas.

Biophilia Upscaling
In response to socio-ecological challenges, cities around the world are implementing greenification and urban forestry. While these strategies contribute to reducing the ecological footprint, they often overlook various social implications. This explains the increasing global attention to Biophilia, which emphasizes human–nature interaction to enhance the quality of urban life. Despite its historical roots spanning centuries, Biophilia is still considered an emerging research field, as shown by debate on evidence-based research and measurement of its multidimensional impacts. Although the beneficial effects of Biophilic Design (BD) are well documented thanks to the small-scale and immediate outcomes, the long-term potential of Biophilic Urbanism (BU) offers less evidence, limiting its utilization and investment.

Big Data-Based Urban Park Research
Urban parks provide multiple benefits to human well-being and human health. Big data provide new and powerful ways to study visitors’ feelings, activities in urban parks, and the effect they themselves have on urban parks. Big data benefits urban park research by providing low-cost, timely information, a people-oriented perspective, and fine-grained site information.

Barriers to Industrial Heritage Reconstruction and Reuse
The reconstruction and reuse of industrial heritage has constituted important means for the protection of that heritage, and has played a crucial role in promoting urban renewal and sustainable urban development. Based on time limits imposed on the completion of any reconstruction and reuse project, the obstacles can be divided into financial and systemic barriers in the early stage of a project and into secondary problems in the latter stage of a project.

Art Galleries in the 8th Arrondissement of Paris
Today in Paris, it is the Marais neighborhood—a sector that started developing in the 1970s but even more in the 1980s and 1990s—that epitomizes the place to be for contemporary art galleries. The implantation of contemporary galleries in Paris clearly results from a historical process that led them from the 8th arrondissement to the Marais, stopping briefly at Saint-Germain-des-Prés (or the 6th arrondissement) mostly for small avant-garde structures.

Appraising Agroecological Urbanism
By the mid-century, urban areas are expected to house two-thirds of the world’s population of approximately 10 billion people. The key challenge will be to provide food for all with fewer farmers in rural areas and limited options for expanding cultivated fields in urban areas, with sustainable soil management being a fundamental criterion for achieving sustainability goals.
