Aufgrund der hohen Konzentration von Bevölkerung, ökonomischen Werten und Infrastrukturen können Städte stark von extremen Wetterereignissen getroffen werden. Insbesondere Hitzewellen und Überflutungen in Folge von Starkregen verursachen in Städten immense gesundheitliche und finanzielle Schäden. Um Schäden zu verringern oder gar zu vermeiden, ist es notwendig, entsprechende Vorsorge- und Klimaanpassungsmaßnahmen zu implementieren.
Im Projekt „Urbane Resilienz gegenüber extremen Wetterereignissen – Typologien und Transfer von Anpassungsstrategien in kleinen Großstädten und Mittelstädten” (ExTrass) lag der Fokus auf den beiden extremen Wetterereignissen Hitze und Starkregen sowie auf kleineren Großstädten (100.000 bis 500.000 Einwohner:innen) und kreisfreien Mittelstädten mit mehr als 50.000 Einwohner:innen. Im Projekt wurde die Stärkung der Klimaresilienz als Verbesserung der Fähigkeiten von Städten, aus vergangenen Ereignissen zu lernen sowie sich an antizipierte Gefahren anzupassen, verstanden. Klimaanpassung wurde demnach als ein Prozess aufgefasst, der durch die Umsetzung von potenziell schadensreduzierenden Maßnahmen beschreib- und operationalisierbar wird.
Das Projekt hatte zwei Ziele: Erstens sollte die Klimaresilienz in den drei Fallstudienstädten Potsdam, Remscheid und Würzburg messbar gestärkt werden. Zweitens sollten Transferpotenziale zwischen Groß- und Mittelstädten in Deutschland identifiziert und besser nutzbar gemacht werden, damit die Wirkung von Pilotvorhaben über die direkt involvierten Städte hinausgehen kann. Im Projekt standen folgende vier Leitfragen im Fokus:
• Wie verbreitet sind Klimaanpassungsaktivitäten in Großstädten und größeren kreisfreien Mittelstädten in Deutschland?
• Welche hemmenden und begünstigenden Faktoren beeinflussen die Klimaanpassung?
• Welche Maßnahmen der Klimaanpassung werden tatsächlich umgesetzt, und wie kann die Umsetzung verbessert werden? Was behindert?
• Inwiefern lassen sich Beispiele guter Praxis auf andere Städte übertragen, adaptieren oder weiterentwickeln?
Die Hauptergebnisse zu diesen Fragestellungen sind im vorliegenden Bericht zusammengefasst.
Social inequalities lead to flood resilience inequalities across social groups, a topic that requires improved documentation and understanding. The objective of this paper is to attend to these differences by investigating self-stated flood recovery across genders in Vietnam as a conceptual replication of earlier results from Germany. This study employs a regression-based analysis of 1,010 respondents divided between a rural coastal and an urban community in Thua Thien-Hue province. The results highlight an important set of recovery process-related variables. The set of relevant variables is similar across genders in terms of inclusion and influence, and includes age, social capital, internal and external support after a flood, perceived severity of previous flood impacts, and the perception of stress-resilience. However, women were affected more heavily by flooding in terms of longer recovery times, which should be accounted for in risk management. Overall, the studied variables perform similarly in Vietnam and Germany. This study, therefore, conceptually replicates previous results suggesting that women display slightly slower recovery levels as well as that psychological variables influence recovery rates more than adverse flood impacts. This provides an indication of the results' potentially robust nature due to the different socio-environmental contexts in Germany and Vietnam.
Resilience trinity
(2020)
Ensuring ecosystem resilience is an intuitive approach to safeguard the functioning of ecosystems and hence the future provisioning of ecosystem services (ES). However, resilience is a multi-faceted concept that is difficult to operationalize. Focusing on resilience mechanisms, such as diversity, network architectures or adaptive capacity, has recently been suggested as means to operationalize resilience. Still, the focus on mechanisms is not specific enough. We suggest a conceptual framework, resilience trinity, to facilitate management based on resilience mechanisms in three distinctive decision contexts and time-horizons: 1) reactive, when there is an imminent threat to ES resilience and a high pressure to act, 2) adjustive, when the threat is known in general but there is still time to adapt management and 3) provident, when time horizons are very long and the nature of the threats is uncertain, leading to a low willingness to act. Resilience has different interpretations and implications at these different time horizons, which also prevail in different disciplines. Social ecology, ecology and engineering are often implicitly focussing on provident, adjustive or reactive resilience, respectively, but these different notions of resilience and their corresponding social, ecological and economic tradeoffs need to be reconciled. Otherwise, we keep risking unintended consequences of reactive actions, or shying away from provident action because of uncertainties that cannot be reduced. The suggested trinity of time horizons and their decision contexts could help ensuring that longer-term management actions are not missed while urgent threats to ES are given priority.
We investigate the effect of the COVID-19 pandemic on self-employed people’s mental health. Using representative longitudinal survey data from Germany, we reveal differential effects by gender: whereas self-employed women experienced a substantial deterioration in their mental health, self-employed men displayed no significant changes up to early 2021. Financial losses are important in explaining these differences. In addition, we find larger mental health responses among self-employed women who were directly affected by government-imposed restrictions and bore an increased childcare burden due to school and daycare closures. We also find that self-employed individuals who are more resilient coped better with the crisis.
Mit Blick auf den Schuldienst existieren viele Studien zur Arbeitsbelastung und Arbeitsbeanspruchung von Lehrkräften. Bereits die Praxisphasen im Lehramtsstudium sind geprägt von zahlreichen Anforderungen für Lehramtsanwärter:innen, weshalb Wissen und Kenntnisse um eigene Ressourcen eine erhebliche Bedeutung für die Ressourcennutzung zur Bewältigung der Anforderungen und zur Gesunderhaltung darstellen. Der vorliegende Beitrag stellt den Gesundheitsbegriff sowie die theoretischen Grundlagen der Ressourcen zur Gesundheitsförderung anhand repräsentativer Studien innerhalb sowie außerhalb des Potsdamer Praxissemesters vor. Insbesondere wird sich den Anforderungen im Praxissemester, die durch die Corona-Pandemie geprägt waren, gewidmet. Ziel ist es, angehenden Lehrkräften die wichtigsten Methoden bzw. Strategien der Gesundheitsförderung zu vermitteln und sie damit zur Stärkung ihrer eigenen Gesundheit auch in Zeiten erhöhter Belastung bzw. in Krisenzeiten zu befähigen. Erste empirische Ergebnisse aus einer qualitativen Erhebung zeigen, dass die Teilnehmenden in Bezug auf innere Ressourcen die zentrale Rolle von produktiven Überzeugungssystemen und produktiven Bewältigungsstrategien betonen. Ein Mentoringprogramm, angelegt analog zur Potsdamer AG der Mentor:innenqualifzierung, könnte dazu dienen, inhaltliche Eckpunkte zur Gesundheitsförderung im Unterricht des Praxissemesters zu verankern und angehende Lehrkräfte zu begleiten.
The intangible impacts of floods on welfare are not well investigated, even though they are important aspects of welfare. Moreover, flooding has gender based impacts on welfare. These differing impacts create a gender based flood risk resilience gap. We study the intangible impacts of flood risk on the subjective well-being of residents in central Vietnam. The measurement of intangible impacts through subjective well-being is a growing field within flood risk research. We find an initial drop in welfare through subjective well-being across genders when a flood is experienced. Male respondents tended to recover their welfare losses by around 80% within 5 years while female respondents were associated with a welfare recovery of around 70%. A monetization of the impacts floods have on an individual’s subjective well-being shows that for the average female respondent, between 41% to 86% of annual income would be required to compensate subjective well-being losses after 5 years of experiencing a flood. The corresponding value for males is 30% to 57% of annual income. This shows that the intangible impacts of flood risk are important (across genders) and need to be integrated into flood (or climate) risk assessments to develop more socially appropriate risk management strategies.
Extreme weather resilience has been defined as being based on three pillars: resistance (the ability to lower impacts), recovery (the ability to bounce back), and adaptive capacity (the ability to learn and improve). These resilience pillars are important both before and after the occurrence of extreme weather events. Extreme weather insurance can influence these pillars of resilience depending on how particular insurance mechanisms are structured. We explore how the lessons learnt from the current best insurance practices can improve resilience to extreme weather events. We employ an extensive inventory of private property and agricultural crop insurance mechanisms to conduct a multi-criteria analysis of insurance market outcomes. We draw conclusions regarding the patterns in the best practice from six European countries to increase resilience. We suggest that requirements to buy a bundle extreme weather event insurance with general insurance packages are strengthened and supported with structures to financing losses through public-private partnerships. Moreover, support for low income households through income vouchers could be provided. Similarly, for the agricultural sector we propose moving towards comprehensive crop yield insurance linked to general agricultural subsidies. In both cases a nationally representative body can coordinate the various stakeholders into acting in concert.
