Article
Full-text available
Coastal areas are urbanizing at unprecedented rates, particularly in low- and middle-income countries. Combinations of long-standing and emerging problems in these urban areas generate vulnerability for human well-being and ecosystems alike. This baseline study provides a spatially explicit global systematization of these problems into typical urba...

Human mortality shows a pronounced temperature dependence. The minimum mortality temperature (MMT) as a characteristic point of the temperature-mortality relationship is influenced by many factors. As MMT estimates are based on case studies, they are sporadic, limited to data-rich regions, and their drivers have not yet been clearly identified acro...
Article
Knowledge on the most exposed areas of a city constitutes an important basis for suitable short and long-term planning. We present and compare three different methods that allow us to assess the potential heat exposure for the smallest administrative spatial units, the quarters, in the German city of Karlsruhe which was repeatedly affected by heat...
Article
As many cities are increasingly affected by heat waves, knowledge regarding those parts of cities most susceptible to heat exposure is essential for the implementation of directed adaptation measures. The frequency of heat waves is projected to increase in both German cities considered for this study: Karlsruhe and Berlin. By aggregating temperatur...

Vulnerability analysis and concept for adaptation to climate change in Berlin, Germany. [Report in German language] Im Dezember 2014 hat die Senatsverwaltung für Stadtentwicklung und Umwelt ein sektoral ausgerichtetes "Konzept zur Anpassung an die Folgen des Klimawandels in Berlin" (AFOK) in Auftrag gegeben. Das vom Potsdam-Institut für Klimafolge...
Article
Cities play a vital role in the global climate change mitigation agenda. City population density is one of the key factors that influence urban energy consumption and the subsequent GHG emissions. However, previous research on the relationship between population density and GHG emissions led to contradictory results due to urban/rural definition co...

Open Access: http://link.springer.com/article/10.1007/s10113-014-0746-1 ----------------------------------------------------------------------------------------------------------------------- This paper presents a method for the analysis of socio-ecological patterns of vulnerability of people being at risk of losing their livelihoods as a conseque...
Article
In order to achieve meaningful climate protection targets at the global scale, each country is called to set national energy policies aimed at reducing energy consumption and carbon emissions. By calculating the monthly heating energy demand of dwellings in the Netherlands, our case study country, we contrast the results with the corresponding aspi...
Article
Full-text available
Motivated by an inconclusive debate over implications of resource scarcity for violent conflict, and common reliance on national data and linear models, we investigate the relationship between socio-ecological vulnerability and armed conflict in global drylands on a subnational level. Our study emanates from a global typology of smallholder farmers...
Book
Full-text available
A methodology to assess future development in patterns of vulnerability is presented which can support the assessment of global policies with regard to their impacts on specific vulnerabilities on the regional or local scale. Patterns of vulnerability, formalized by vulnerability profiles (e.g. for the livelihoods of dryland smallholder farmers) we...
Conference Paper
Full-text available
The management of transformative processes requires a sound understanding of the relation between socio-ecological systems and stress impacting upon them. Within the multitude of conditions determining this relation, distinct processes recur in various regions inspiring research on typologies, that is to say typical patterns of underlying condition...
Conference Paper
Full-text available
Context of application The recurrence of specific processes that shape farmers’ vulnerability to environmental and socio-economic perturbations in various regions has inspired research on archetypical patterns of vulnerability. This presentation assesses patterns of vulnerability to climate variability, market impacts and demographic perturbations...
Chapter
We distinguish climate change regions of Europe in a spatially explicit way. For this we apply a cluster analysis of impact related climatic indicators for the years 1961-1990 to 2071-2100 under scenario A1B. A high spatial resolution is achieved by using the regional climate model CCLM with a grid edge length of around 20 km. We overcome the chall...
Article
The electricity system is particularly susceptible to climate change due to the close interconnectedness between electricity production, consumption and climate. This study provides a country based relative analysis of 21 European countries’ electricity system susceptibility to climate change. Taking into account 14 quantitative influencing factors...
Chapter
Climate change will bring about a sea change in environmental conditions worldwide during the 21th century. In particular, most of the extreme events and natural disaster regimes prevailing today will be transformed, thus exposing innumerable natural and socioeconomic systems to novel risks that will be difficult to cope with. This crucial componen...

Der vorliegende Leitfaden basiert auf den Ergebnissen eines dreijährigen Forschungsprojektes mit dem Namen „Kritische Infrastruktur, Bevölkerung und Bevölkerungsschutz im Kontext klimawandelbeeinflusster Extremwetterereignisse (KIBEX)“. Finanziell gefördert und fachlich begleitet wurde das Projekt durch das Bundesamt für Bevölkerungsschutz und Kata...
Conference Paper

Specific processes that shape the vulnerability of socio-ecological systems to climate, market and other stresses derive from diverse background conditions. Within the multitude of vulnerability-creating mechanisms, distinct processes recur in various regions inspiring research on typical patterns of vulnerability. The vulnerability patterns displa...
Book
Full-text available
In coupled human-environment systems where well established and proven general theories are often lacking cluster analysis provides the possibility to discover regularities – a first step in empirically based theory building. The aim of this report is to share the experiences and knowledge on cluster analysis we gained in several applications in th...
Article
Full-text available
The assessment of coastal flood risks in a particular region requires the estimation of typical damages caused by storm surges of certain characteristics and annualities. Although the damage depends on a multitude of factors, including flow velocity, duration of flood, precaution, etc., the relationship between flood events and the corresponding av...
Article
Sea level rise is going to affect the statistics of extreme sea levels. If one wants to calculate damages due to upcoming storm surges, it is necessary to estimate the damage due to individual flood events. In the case of (coastal) floods, so called stage damage functions are employed, which provide for a flood of certain maximum level a typical da...
Article
Full-text available
The relevance of climate change is especially apparent through the impacts it has on natural and societal systems. A standardised methodology to assess these impacts in order to produce comparable results is still lacking. We propose a semi-quantitative approach to calculate vulnerability to climate change, with the ability to capture complex mecha...
Article
Drylands display specific vulnerability-creating mechanisms which threaten ecosystems and human well-being. The upscaling of successful interventions to reduce vulnerability arises as an important, but challenging aim, since drylands are not homogenous. To support this aim, we present the first attempt to categorise dryland vulnerability at a globa...
