Urban areas at risk of river flooding
In many parts of Europe, the risk of river flooding is expected to increase; in north-eastern Europe, the probability of floods is expected to fall. Further to climate exposure, the placement of many new urban areas and the accumulation of assets in low-lying areas close to rivers has intensified the sensitivity to river floods. The map shows the low-lying urban areas potentially threatened by river flooding in a one-in-a-century flood event, both for the current period and in the projected future. However, the map does not take into account eventual future changes in urban land-take, nor any adaptation measures like flood defences or flood retention that may lower the risk.
Slowdown of urban growth
Historical trends and projections by world regions (1950- 2050) of urban growth rate showing a clear slowdown for all regions
Social capital — trust in other people (synthetic index 0–100), 2009
The map shows the perception of the cities’ population on their trust in other people living in the city; it is therefore a proxy for social capital.
Spanish and Portuguese signatories of the Covenant of Mayors and Mayors Adapt
Cities around Europe have begun to actively integrate adaptation needs in coastal zone management. They are bringing together sectors and interests that have traditionally operated separately, for example in Lithuania, Northern Ireland and Spain. Bologna, Italy, provides an example of a broad range of public and private stakeholders collaborating in urban planning to support resilience.
Urban climate analysis map for the city of Arnhem, the Netherlands
The map shows different climate classifications of the areas in the city of Arnheim
Urban trends
Historical urban population trends and projections by world regions (1950- 2050), showing the share of cities with less than 750 000 inhabitants
Vulnerable people — the elderly are considered to be a group more sensitive to various climatic stress factors than people of a working age
The map shows the share of elderly people (>= 65 years) within a city (represented by the dot colours) to the total population (represented by dot size).
Wastewater treatment in 601 Mediterranean coastal cities with a polution greater than 10000

Number of cities greater than 50 000 inhabitants by country
Cities within each country have been differentiated according to the number of inhabitants.
Participation of 650 European cities in European and global city initiatives related to adaptation
The map list the number of European and international initiatives with a relation to climate-change adaptation in which cities are envolved. These initiatives are Mayors Adapt/Covenant of Mayors for Climate and Energy, the Compact of Mayors, C40 with adaptation action, Making Cities Resilient (United Nations Office for Disaster Risk Reduction, UNISDR), the European Green Capital Award, European Green Leaf and Rockefeller 100 resilient cities initiative.
Percentage of green and blue urban areas — share of cities per class per country
The diagram shows the proportion of cities per country that falls in a particular class regarding the share of green and blue urban areas.
Percentage of population aged ≥ 65 — share of cities per class per country
The diagram shows the proportion of cities per country that fall in a particular class regarding the share of citizens which are older than 64 years.
Percentage of the city that would be flooded in case rivers rise one metre
Percentage of the city that would be flooded in case water in rivers rises 1 m (only cities > 100 000 hab). The city is defined by its biophysical delineation (Urban Morphological Zone) inside the core city boundaries (Urban Audit). The background shows the relative change in 100-year return level of river discharge. Neither coastal floods nor flood protection measures are considered in the calculations.
Percentage of the urban area that would be flooded — share of cities per class per country
The diagram shows the proportion of cities per country that fall in a particular class regarding the percentage of potentially flooded area.
Potential inundation exposure for coastal cities due to projected sea level rise and storm surge events
The map shows the proportion of the city area (UMZ inside the core city) that would be affected by potential inundation caused by a sea level rise of 1m.
Water stress indicator WEI for annual average on river basin level for the a) baseline, b) 2050 under the 'economy comes first' scenario, and c) compared with urban population numbers
Annual average water stress indicator WEI on river basin level for baseline and 2050 period with SCENES scenario Economy First (EcF)
Relative change of mean annual storm loss potential on nine GCM (upper row) and eight RCM (bottom row) simulations for 2071–2100 compared to 1961–2000 (SRES A1B scenario)

Net land take in cities and commuting zones in Europe
Conversion of natural land to artificial surfaces continues to undermine ecological functions and weaken ecosystem resilience. The EU Member State average net land take increased by about 32% in cities and their commuting zones, from 410km²/year during 2012-2018 to 540km²/year in 2018-2021. Most conversions affected cropland and pastures, followed by forests. Achieving the EU's goal of no net land take by 2050 will require major reductions amid ongoing urban expansion. However, given the upward trend observed between 2012 and 2021, Europe is currently likely off track to meet this target.
Equity — percentage of women among elected city representatives, 2004
The map shows the proportion of women who are elected as city representatives
European urban population trends
The graph shows the proportion of urban population of the overall population in Europe and the absolute numbers of urban population over time
Urban areas at risk of forest fire
The map provides an overview of the extent of urban areas at higher risk of being directly affected by forest fires (burning down) under current conditions.
Annual growth of built-up areas from the mid-1950s to the late 1990s, selected European cities
Annual number of nights of thermal discomfort
The map shows that southern cities can experience daytime conditions that represent slight to moderate heat stress at the very least. Many southern cities have also a high share of elderly people. The map does not yet show future projections of thermal discomfort in cities, although it is expected that discomfort in more northern cities will increase.
