Gini 2021: Urban scaling and Zipf law are closely related our detailed study show. Results supports they idea that urban scaling does not solely emerge from intra-city processes, as population distribution and scaling of urban GDP are correlated to each other. Further details in PlosOne 16(1): e0245771
Building volume and surface temperature
2020: Due to lack of data it is difficult to assess urban heat islands (UHI) In a recent article most influential factors of UHI have been identified. It was shown building volume is highly relevant. Results also indicate that polycentric are in favour in comparison to monocentric cities. This helps future city planning and to cope with adverse consequences. Details in Nature Comm. 11: 2647
Potential for near urban food production
2019/20: Local production matters for climate protection, but not at any price. For more than 4000 cities worldwide the potential of local food production have been evaluated. It can be shown that > 30% of urban residents could be nourished by near urban food production, but climate change, urban growth and changing nourishment would have a tremendous impact on the local potential and will decrease it considerably. Details: ERL 14(9): 094007 Env. Sci. & Tech. 54(17): 10551 [press release] .
Isolines: population vs. area
2019: Reducing urban carbon footprints is pivotal for achieving climate protection targets, but which factors are forcing urban emissions remains unclear. A recent study based on a Cobb-Douglas approach estimated contributions of population size or urban density. The larger the city, the higher is the impact of changing its population or density, but population changes always have a greater effect on emissions than population density. Details:Nature Comm. 10: 3204.
urban Kaya 2019: An extension of the well-known Kaya identity to urban systems show that cities in the developing world have some leap-frogging potential. While GDP doubling in OECD cities comes together with a doubling of energy consumptions (and equivalent emissions). This can be explained by established life styles and infrastructure lock-ins. This does not hold for cities in the developing world. [Urban Kaya].
                                          Based Initiatives 2018: It is broadly discussed if and how community based initiatives can contribute to the sustainability challenge. While many of these initiatives are based on voluntary work it can be shown that its mitigation potential can be tremendous. If only 5% of European citizens would engage in CBIs the achievement of climate protection targets could be easily achieved (cf. also TESS project) [CBI].
                                          School of Sustainable Futures 2018: Berlin School for Sustainable Futures(BSSF), a University of Applied Sciences, will start 2020 after receiving its final approval from German Council of Science and Humanities and Berlin Governing Mayor/Senate Chancellery – Higher Education and Research. BSSF is a private University bringing together sustainability challenges, cultural transformation needs, and digital humanism via by advanced and modern curricula. J.P. Kropp acts as founding dean for the sustainability department and is a designated board member. [BSSF].
ICIMOD 2018: J. Kropp became appointed member of the board of directors of the International Centre for Integrated Mountain Development (ICIMOD). ICIMOD deals with environmental challenges in mountainous regions, is operated by all countries who owns a part of the Himalaya/Hindukush region, and has its headquarter in Kathmandu/Nepal.
SDGs 2018: The publishing of Sustainable Development Goals was a seminal political achievement. Now a framework exists that helps to tackle deficits in human and environmental development. However, the complex multi-dimensional challenges are difficult to analyse and so far little is known about the interactions, correlations and potential conflicts between the set of SDGs. With our article we tried to break up the complicated interlinkages and investigate how different SDGs influence each other [Article], [Press Release].
Urban Issues 2017/2018: In the last 12 months several papers have been finalised which have been prepared in the RAMSES project. They show that that cities can be analysed from a systematic point of view coarse resolutions can provide huge valuable insights about cities, their dynamics, and about potential transformations. Moreover, several documents have been published which supports city planners in their resilience planning, e.g. RAMSES Transition Handbook and Training Package.

RAMSES Logo 2017: The European funded 5yr project RAMSES (final report) has bin finished with an international conference entitled Cities and Climate Change Conference 2017 at Potsdam Institute for Climate Impact Research More than 170 researchers from accross the globe explored the latest advances in research and practice addressing climate change in cities, including issues of infrastructure, planning, governance, economics of adaptation, risk management, health prevention and their possible trade-offs and synergies with sustainability objectives.
European Energy
                                          Week 2017: The three H2020 funded sister projects INNOPATH, REINVENT and EUCalc organised a session on the European Energy Week 2017. The coordinators P. Ekins, L. Nilsson (Lund), and J. Kropp (Potsdam) shared their views about a European Sustainability Transformation and what is needed to get there [Conference Website].
EUCalc 2016: European Union supports the development of a European Model to foster societal and technological transformation with more than 5m €. The idea for the project relies on the Global Calculator which was motivated by UK Dept. of Energy and Climate Change. The new model will be downscaled on member state level, allows detailed trade-off analyses and will be user friendly, i.e. is usable by stakeholders. [EUCalc website, Global Calculator website].
TESS 2016: Towards European Sustainable Societies (TESS) FP7 project has been finished. The aim of the project was to assess the impact of community based initiatives on climate protection targets. I has been estimated that in case of voluntary engagements of only 5% of all European citizens climate protection targets would be easily achievable. Details of the assessment and tools can be found on the TESS website. [TESS website, Track It! Tool ].
Urban Scaling 2016: The scaling analysis of CO2 emissions in cities with population size suggests an exponent which is development dependent with a transition from super- to sub-linear scaling. From mitigation point of view, the results imply that urbanization is desirable in developed countries, but not in developing countries, evt. a hint of an export of pollutant intensive industries into developing countries [link to article].
Food Waste 2016: In a recently published article we estimated the effect of food surplus and waste on climate change. 10% of all emissions from agriculture are related to food waste. Besides these results a previously published article showed the increasing relevance of agriculture for future greenhouse gas emissions in particular if lifestyle and demographic change is considered [link to article] [press release].
                                          emissions 2016: Urban sprawl leads to more emissions from cities. An analysis of all inhabited areas in the US show a sub-linear relationship between population density and total emissions (i.e. on-road and buildings). A doubling of the population density would entail a reduction of total CO2 emissions in buildings and on-road sectors typically by at least 42%. Population density exerts a higher influence on on-road emissions than buildings emissions. [link to article]
Damage Assessment 2016: A new study provides a method to quantify monetary losses from coastal floods and on city level under sea-level rise. For the first time, the scientists show that the damage costs consistently increase at a higher rate than the sea-level rise itself [link to article] [press release].
Residential Heat 2015: Energy (and emission) savings from housing sector needs much more investements and an almost doubled renovation rate if self-defined targets of energy reduction should come true in 2050 in the Netherlands. This confirms a previous study, which was published already in 2011 and which investigated the the German residential sector [link to article] [ article 2011].

                                          Calories in Meat 2013: On a global scale, about 40% of the global crop calories currently are used as livestock feed and about 4 kcal of crop products are used to generate 1 kcal of animal products. Concering future demographic growth and dietary changes will almost double global fed demand by 2050. Securing food availability could be therefore threatened by an overproportional meat consumption  [link to article].
                                          Island Effect 2013: Cities heat up stronger than the rural regions surrounding them – and if climate change continues, this will become a risk for the inhabitants. On the basis of satellite data, researchers have now more comprehensively than ever before investigated this so-called heat island effect for thousands of cities in Europe [link to article] [press release]
Development dynamics 2013: Development dynamics from an agrarian towards an industry and to a service oriented economy can be described by simple system of differential equations based on kinetic equations [link to article]
Emissions from
                                          agriculture 2013: Greenhouse gas emissions from agriculture may triple by 2050 in comparison to 2005, if dietary changes and demographic growth is considered. A systematic identification of global nourishment styles and its relation to the human development level indicates that agriculture may become a major contributor to greenhouse gas emissions [link to article]
                                          in Sustainability 2012-2014: JP Kropp Appointed Founding and Editor-in-Chief of the New Journal: Challenges in Sustainability.
RAMSES 2012: Five year Project on Cities (RAMSES) received funding of about 5.2 mln Euros from the European Union. The project will be coordinated by PIK and runs under the rooftop of the Climate Change and Development Group/Sustainable Cities Flagship [link to website] [CCD Group] [project trailer].
Emission Burden Sharing 2011: The integration of developing countries into global CO2 reduction schemes needs a fair burden
sharing. In our approach for balancing climate change mitigation it is shown that human development might be a measure to come to an more objective burden sharing amongst countries, but it also shows that contributions from industrialised countries must be even much larger [link to article] [press release].
