In 2002, Prague experienced severe flooding with total damage of 24 billion CZK (1 billion euro). This event was recognized as one of the most expensive weather-related disaster in the history of the city with heavy damages on infrastructure, housing and environment. Future climate scenarios predict a change in the number and intensity of extreme events, inter alia, increasing the risk of river flooding. Since the 2002 event, the implementation of flood control measures by Prague municipality substantially speeded up.

The area of the Eferdinger Becken, Upper Austria, is a small area that lies on the Danube. It has no protection against floods with a 100-year return time: the flood-prone area includes about 154 houses that flood regularly. Due to the importance of the retention space for the discharge and the difficult technical feasibility, passive flood protection was considered as more suitable. Homeowners needed to decide on relocation by the end of 2015. The federal and the regional governments compensate citizens 80% of the value of the house if they agree to move.

Isola Vicentina (Italy) signed the EU’s Mayors Adapt initiative (current Covenant of Mayors for Climate and Energy) in 2014 and since then started the elaboration process of its Municipal Water Management Plan (MWMP) in order to integrate climate change adaptation into its water management policies. For this purpose, Isola Vicentina Mayor engaged the “Planning Climate Change” research group at the IUAV University of Venice and Green-Dev studio, a local consultancy firm.

Normally a shallow river, the White Cart Water was prone to flash flooding. Its water levels can rise by six metres after just 12 hours of rain, which threatened vulnerable Glasgow suburbs downstream. Public awareness of such flooding risks in the 1980s and 1990s, and projections of more intense periods of rainfall made devising a flood prevention scheme a priority for the Glasgow City Council.

Settlements, infrastructure, land use and road connections in the Grimsel area in southern Switzerland are heavily exposed to risks from hydrological and gravitational natural hazard processes, such as rock fall, mudflows, landslides, avalanches, and floods favoured by sedimentation of debris. Permafrost thawing, glacier retreat, and more frequent heavy rainfall events due to climate change are expected to further decrease slope stability and increase likelihood of mass movements.

Evidence that elevated temperatures can lead to increased mortality and morbidity is well documented, with population vulnerability being location specific. The elderly are particular vulnerable to extreme heat stress. Being part of the Iberian Peninsula, Portugal has a mild Mediterranean climate. Climate change projections indicate that the number of days with extreme heat in Portugal will increase with urban areas being more sensitive.

Demographic change and climate change together place great challenges on the society. The life expectancy of the population in Germany rises and so does the share of older people. Besides chronic patients and children, the elderly are especially affected by the effects of the climate change. At the same time more and more people live in single person households (increase from 14.56 million in 2004 to 16.83 million in 2016 in Germany), which can influence their social isolation.

The Vistula River is a 1,046 km long river which springs in southern Poland and ends in the Baltic Sea. The Upper Vistula extends over the three Polish provinces of Małopolskie, Podkarpackie and Swietokrzyskie. The Upper Vistula region covers an area of 43,000 km², including the cities of Krakow, Tarnow, Kielce, Nowy Sacz, Rzeszow, Przemysl and Krosno. The area is also known for its extraordinary natural values. The region is prone to flood risk both in winter and in summer.

Bologna, like many Southern European cities, is facing drought, extreme temperatures and water scarcity as a result of climate change. With no national or regional adaptation action plan still in place, the city of Bologna took it upon themselves to draft an Adaptation Plan to Climate Change. The plan, which was approved by the City Council on October 2015, focuses on the development of innovative, concrete measures that could be tested locally.

Climate change impacts are expected to strongly impact the Madrid region and include extreme heat in summer, water scarcity and occasional heavy rainfall.
