In current times, highly complex and urgent policy problems—e.g., climate change, rapid urbanization, equitable access to key services, land rights, and massive human resettlement—challenge citizens, NGOs, private corporations, and governments at all levels. These policy problems, often called 'wicked', involve multiple causal factors, anticipated and unanticipated effects, as well as high levels of disagreement among stakeholders about the nature of the problem and the appropriateness of solutions. Given the wickedness of such policy problems, interdisciplinary and longitudinal research is required, integrating and harnessing the diverse skills and knowledge of urban planners, anthropologists, geographers, geo-information scientists, economists, and others. This Special Issue promotes innovative concepts, methods, and tools, as well as the role of geo-information, to help (1) analyze alternative policy solutions, (2) facilitate stakeholder dialogue, and (3) explore possibilities for tackling wicked problems related to climate change, rapid urbanization, equitable access to key services (such as water and health), land rights, and human resettlements in high-, middle-, and low-income countries in the North and South. Such integrative approaches can deepen our understanding of how different levels of government and governance reach consensus, despite diverging beliefs and preferences. Due to the particularly complex spatiotemporal characteristics of wicked policy problems, innovative concepts, alternative methods, and new geo-information tools play a significant role.

Cities are recognised as key players in global adaptation and mitigation efforts because the majority of people live in cities. However, in Europe, which is highly urbanized and one of the most advanced regions in terms of environmental policies, there is considerable diversity in the regional distribution, ambition and scope of climate change responses. This paper explores potential factors contributing to such diversity in 200 large and medium-sized cities across 11 European countries. We statistically investigate institutional, socio-economic, environmental and vulnerability characteristics of cities as potential drivers of or barriers to the development of urban climate change plans. Our results show that factors such as membership of climate networks, population size, GDP per capita and adaptive capacity act as drivers of mitigation and adaptation plans. By contrast, factors such as the unemployment rate, warmer summers, proximity to the coast and projected exposure to future climate impacts act as barriers. We see that, overall, it is predominantly large and prosperous cities that engage in climate planning, while vulnerable cities and those at risk of severe climate impacts in the future are less active. Our analysis suggests that climate change planning in European cities is not proactive, i.e. not significantly influenced by anticipated future impacts. Instead, we found that the current adaptive capacity of a city significantly relates to climate planning. Along with the need to further explore these relations, we see a need for more economic and institutional support for smaller and less resourceful cities and those at high risk from climate change impacts in the future.

Heat and increasing ambient temperatures under climate change represent a serious threat to human health in cities. Heat exposure has been studied extensively at a global scale. Studies comparing a defined temperature threshold with the future daytime temperature during a certain period of time, had concluded an increase in threat to human health. Such findings however do not explicitly account for possible changes in future human heat adaptation and might even overestimate heat exposure. Thus, heat adaptation and its development is still unclear. Human heat adaptation refers to the local temperature to which populations are adjusted to. It can be inferred from the lowest point of the U- or V-shaped heat-mortality relationship (HMR), the Minimum Mortality Temperature (MMT). While epidemiological studies inform on the MMT at the city scale for case studies, a general model applicable at the global scale to infer on temporal change in MMTs had not yet been realised. The conventional approach depends on data availability, their ...

Das vorliegende UFZ-Diskussionspapier ist die Dokumentation des Workshops Schrumpfung und Urban Sprawl, der am 3. November 2003 am UFZ stattfand. Es führt damit eine Diskussions- und Forschungslinie fort, die in den 1990er Jahren durch Forscher und Praktiker aus unterschiedlichen Einrichtungen der Region Halle-Leipzig begründet wurde. Im Arbeitskreis Suburbanisierung wurden unter Koordination des UFZ disziplinäre Zugänge und praktische Erfahrungen zusammengeführt und daraus Handlungsempfehlungen abgeleitet. Zwischenzeitlich hat der Suburbanisierungsdruck, der noch Ende der 1990er Jahre konstatiert wurde, deutlich abgenommen nicht nur in der Region, sondern in ganz Ostdeutschland. Nichtsdestoweniger ist Suburbanisierung ein zentraler Gegenstand von raumbezogener Politik und räumlicher Planung geblieben und hat im Zusammenhang mit dem Thema Stadtumbau neue Relevanz gewonnen. So ist davon auszugehen, dass auch in der Region Halle-Leipzig die intensive Beschäftigung mit dem Problem der Suburbanisierung anhalten wird allerdings unter veränderten Vorzeichen. Im Mittelpunkt steht nunmehr die Frage, welche Anforderungen sich aus der Situation von demographischer und städtischer Schrumpfung für die wissenschaftliche und praktische Auseinandersetzung mit Suburbanisierung ergeben. So gilt es, unter anderem, zu klären, ob sich die Richtung von Sprawl unter Schrumpfungsbedingungen umkehrt, ob das Zusammenspiel von Schrumpfung und Sprawl zu einer neuen Stadtstruktur führt oder ob sich durch diese spezifische Situation die Segregationsmuster verändern. Auf dem Workshop selbst wurden vor allem die Möglichkeiten der Steuerung von Suburbanisierung bzw. Sprawl unter Schrumpfungsbedingungen behandelt. Dazu wurden Überlegungen und Ergebnisse, die im EU-Projekt URBS PANDENS am Fallbeispiel Leipzig gewonnen wurden, vorgestellt, diskutiert und mit Erfahrungen aus der Praxis bzw. aus einer anderen Region konfrontiert. Neben der empirischen Analyse spielt dabei ein im Rahmen von URBS PANDENS entwickeltes qualitatives Modell des Urban Sprawl eine zentrale Rolle.

International audience ; Climate Action Planning is one of the top priorities of cities in order to reduce greenhouse gas emissions and strengthening climate-resilience, as pointed out by the New Urban Agenda and the Paris Agreement. This study aims at assessing the development of climate change mitigation and adaptation planning in Italian cities. To this end, we analysed the availability of Local Climate Plans (LCPs) in 76 cities, which are included in the Eurostat Urban Audit (UA-2015) database. In a further step, we analysed the content of the urban climate change mitigation and adaptation plans available in a smaller sample of 32 Italian cities of 2007 Eurostat Urban Audit database (UA-3), looking at the single actions undertaken for addressing mitigation and adaptation to climate change. Results show the almost total absence of comprehensive and stand-alone urban climate change adaptation plans in Italy (except for two cities, Ancona and Bologna), whereas we found that in 61 out of 76 cities municipal civil protection plans are the instruments that deal with local emergencies associated to extreme weather events. On the other hand, 56 out of 76 urban climate change mitigation plans (i.e. Sustainable Energy Action Plans) are being developed in the framework of the Covenant of Mayors, which is a transnational network of local governments created by the European Union (EU) in 2012. The results obtained on the mitigation side point out that, in absence of a national law that imposes Italian cities to develop LCPs, transnational networks are an effective boost to voluntary commitment to reach EU climate and energy objectives.

Cities significantly contribute to climate change and at the same time have governance capacity to act efficiently in the field s of mitigation and adaptation. Their capacity is being increasi ngly recognized by international institutions and has been pointed out as crucial i n the multi-level government scenario of the European Union (EU). Addressing the ch allenges of climate change at urban level is a complex issue w hich requires a holistic approach to strategic urban planning. Unders tanding why and how cities start action can help to identify th e barriers they face when addressing climate change, and how national government s, regions and international bodi es can support local authoriti es in their climate fight. This work aims to contribute to the provision of the knowledge needed to gain a better and deeper insight into u rban climate action. The study investigates the state-of -the-art of urban climate plans in Spain and Italy, two countries which share simila rities on many levels (i.e. cultural, geographical, climate vulnerabilities, urban configurations and institutional framework). The research a nalyses cities that are included in the Eurostat Urban Audit (U A), 26 in Spain and 32 in Italy, focusing on the actions taken by large and medium m unicipalities in reducing their contribution to climate change and becoming mo re resilient to changing weather patterns. The results of the a nalysis show a trend towards increasing awarene ss of climate mitigation (highly focused on ener gy efficiency and the promotion of cleaner ener gy sources), while adaptation remains a local policy area in its infancy in both countries. The study also identifies the beneficial influen ce of national and international climate city networks.
