River and coastal flooding have affected many millions of people in Europe since 2000. Flooding affects human health through drowning, heart attacks, injuries, infections, exposure to chemical hazards and mental health consequences. Disruption of services, including health services, safe water, sanitation and transportation ways, plays a major role in vulnerability. Observed increases in heavy precipitation and extreme coastal water levels have increased the risk of river and coastal flooding in many European regions. In the absence of additional adaptation, the projected increases in extreme precipitation events and in sea level would substantially increase the health risks associated with river and coastal flooding in Europe.

Past trends

Most regions in Europe have exhibited an increasing trend in heavy precipitation over recent decades, in particular in winter. The number of large inland floods in Europe has been increasing since the 1980s; however, there is not yet conclusive evidence that climate change has already contributed to this trend [i].

Estimates for the World Health Organization (WHO) European Region based on a combination of data from the Emergency Events Database (EM-DAT) and the Dartmouth Flood Observatory (DFO) indicate that coastal and inland floods killed more than 2 000 people and affected 8.7 million in the period 2000–2014. Figure 1 shows the number of deaths related to flooding in each European Environment Agency (EEA) member and cooperating country for the same period, normalised by their population. The largest numbers are found in south-eastern Europe, eastern Europe and central Europe. Note that, because of the relatively short time period of 15 years, the value of the indicator can be significantly affected by a single catastrophic event. For example, at least 50 people were killed in massive floods in the Balkan countries in May 2014 [ii].

The EM-DAT database also includes data on people injured or (otherwise) affected by floods. This information is not presented here owing to concerns regarding the consistency with which these data are assessed and reported across countries and even for different flood events in the same country.

Projections

Heavy precipitation events are likely to become more frequent in many regions in Europe, and sea level rise is projected to accelerate compared with the 20th century under all emissions scenarios. The PESETA II project and the ClimateCost project have estimated the economic and health effects of river and coastal flooding under various climate change scenarios, including sea level rise.

For a medium emissions scenario (IPCC Special Report on Emissions Scenarios (SRES) A1B) and in the absence of adaptation, river flooding is estimated to affect about 300 000 people per year in the EU by the 2050s and 390 000 people by the 2080s; the latter figure corresponds to more than a doubling with respect to the baseline period (1961–1990). The British Isles, western Europe and northern Italy show a robust increase in future flood hazards; these regions also show the greatest increase in the population affected by river floods [iii].

If no additional adaptation measures were taken, the number of people affected by coastal flooding in the EU at the end of the 21st century would range from 775 000 to 5.5 million people annually, depending on the emissions scenario. The number of deaths in the EU due to coastal flooding in the 2080s would increase by 3 000, 620 and 150 per year under a high emissions scenario (assuming 88 cm sea level rise), the SRES A1B ‘business as usual’ scenario and the E1 mitigation scenario, respectively. Two-thirds of these deaths would occur in western Europe. Coastal adaptation measures (dikes and beach nourishment) could significantly reduce risks to less than 10 deaths per year in 2080 [iv]. Somewhat different estimates were provided in another study [v].

Flooding is also associated with mental health impacts. Coastal flooding in the EU could potentially cause five million additional cases of mild depression annually by the end of the 21st century under a high sea level rise scenario in the absence of adaptation [vi].

Policy context and targets

Context description

In April 2013, the European Commission (EC) presented the EU Adaptation Strategy Package. This package consists of the EU Strategy on adaptation to climate change (COM/2013/216 final) and a number of supporting documents. The overall aim of the EU Adaptation Strategy is to contribute to a more climate-resilient Europe.

One of the objectives of the EU Adaptation Strategy is Better informed decision-making, which will be achieved by bridging the knowledge gap and further developing the European climate adaptation platform (Climate-ADAPT) as the ‘one-stop shop’ for adaptation information in Europe. Climate-ADAPT has been developed jointly by the EC and the EEA to share knowledge on (1) observed and projected climate change and its impacts on environmental and social systems and on human health, (2) relevant research, (3) EU, transnational, national and subnational adaptation strategies and plans, and (4) adaptation case studies.

Further objectives include Promoting adaptation in key vulnerables ectors through climate-proofing EU sector policies and Promoting action by Member States. Most EU Member States have already adopted national adaptation strategies and many have also prepared action plans on climate change adaptation. The EC also supports adaptation in cities through the Covenant of Mayors for Climate and Energy initiative.

In September 2016, the EC presented an indicative roadmap for the evaluation of the EU Adaptation Strategy by 2018.

In November 2013, the European Parliament and the European Council adopted the 7th EU Environment Action Programme (7th EAP) to 2020, ‘Living well, within the limits of our planet’. The 7th EAP is intended to help guide EU action on environment and climate change up to and beyond 2020. It highlights that ‘Action to mitigate and adapt to climate change will increase the resilience of the Union’s economy and society, while stimulating innovation and protecting the Union’s natural resources.’ Consequently, several priority objectives of the 7th EAP refer to climate change adaptation.

    In April 2013, the European Commission adopted an EU strategy on adaptation to climate change, which has been welcomed by the EU Member States. The strategy aims to make Europe more climate-resilient. By taking a coherent approach and providing for improved coordination, it enhances the preparedness and capacity of all governance levels to respond to the impacts of climate change.
  • Implementing the European Regional Framework for Action to protect health from climate change
    How far have Member States in the WHO European Region progressed in implementing the European Commitment to Act on climate change and health? This was the question addressed to members of the Working Group on Health in Climate Change (HIC) of the European Environment and Health Task Force in summer 2012. The HIC members were asked to respond to a comprehensive questionnaire to assess the current status of health-relevant climate change mitigation and adaptation actions. A total of 22 Member States answered the questions focusing on eight thematic areas or topics: governance, vulnerability, impact and adaptation assessments, national and subnational adaptation strategies, climate-change mitigation, strengthening of health systems, awareness raising and capacity building, green health services and sharing best practices. This publication describes and analyses their responses.

Data sets uncertainty

The attribution of health effects to climate change is difficult owing to the complexity of interactions and the potential modifying effects of a range of other factors (such as land-use changes, public health preparedness and socio-economic conditions). Criteria for defining a climate-sensitive health impact are not always well identified, and their detection sometimes relies on complex observational or prospective studies, applying a mix of epidemiological, statistical and/or modelling methodologies. Furthermore, these criteria, as well as the completeness and reliability of observations, may differ between regions and/or institutions, and they may change over time. Data availability and quality are crucial in climate change and human health assessments, both for longer term changes in climate-sensitive health outcomes and for health impacts of extreme events. The monitoring of climate-sensitive health effects is currently fragmentary and heterogeneous. All these factors make it difficult to identify significant trends in climate-sensitive health outcomes over time, and to compare them across regions. In the absence of reliable time series, more complex approaches are often used to assess the past, current and future impacts of climate change on human health.

The links between climate change and health have been the subject of intense research in Europe in the early 2000s (e.g. the projects cCASHh, EDEN, EDENext and Climate-TRAP); more recently health has been incorporated, to a minor extent, into some cross-sectorial projects (e.g. CIRCE, PESETA II, IMPACT2C and RAMSES). Furthermore, the World Health Organization (WHO) has a policy, country support and research mandate given by its 193 Member States through the World Health Assembly on all aspects of climate change and health.
