CCRA research

The CCC has commissioned research projects to feed into the technical chapters, with funding from the UK Department for Environment, Food and Rural Affairs (Defra); the Devolved Administrations; the Natural Environment Research Council (NERC); the Economic and Social Research Council (ESRC); and the Engineering and Physical Sciences Research Council (EPSRC).

Projections of Future Flood Risk

Led by Sayers and Partners

The CCC previously commissioned projections of current and future flood risk for the UK to inform the CCRA2 Evidence Report. This project updates those projections for the CCRA3 Evidence Report to take into account the new UKCP18 climate projections and the latest understanding of flood risk calculations and flood risk management policies. The project looks at river, coastal, surface water and groundwater flooding, and takes into account climate change, population growth and adaptation to project various metrics of flood risk (e.g. properties, people and assets exposed as well as annual expected damages) in the mid and late century for each of the four UK countries.

Projections of Future Water Availability

Led by HR Wallingford

The CCC previously commissioned projections of current and future water availability for the UK to inform the CCRA2 Evidence Report. This project updates those projections for the CCRA3 Evidence Report to take into account the new UKCP18 climate projections and the latest plans from water companies. The project looks at both the demand for and supply of water, and takes into account population growth and climate change to project how much water will be available in the mid and late century for each of the four UK countries. The project reports results for the public water supply and also for ‘all sectors’ which includes the demands of agriculture, energy generation, industry and the environment.

Understanding how behaviours can influence climate change risks

Led by AECOM

This project addresses a key evidence gap from the CCRA2 Evidence Report on how the behaviour of individuals, communities and businesses affects vulnerability and exposure to a range of climate change risks, including flooding, heat, drought, and storms. It includes a set of case studies from locations around the UK: 1.Orkney Islands, 2. Greater Manchester, 3. London Borough of Lewisham, 4. Peebles, Scottish Borders 5. Llechryd, Ceredigion, Wales 6. Northern Ireland 7.UK-wide (responses to water scarcity).

Climate-driven threshold effects in the natural environment

Led by UKCEH

This project assesses a key evidence gap from the CCRA2 Evidence Report on climate-driven threshold (i.e. non-linear) effects within the natural environment, and the role of adaptation (natural and human responses) in moderating those threshold effects. A threshold is defined in the study as “the point at which a non-linear change in an ecosystem component occurs as a result of change in a climate driver”. The report assesses threshold effects in the following habitat types; freshwater, farmland and grasslands, peatlands, woodlands, marine and coastal margins.


Front cover of Interacting risks in infrastructure, the built and natural environments

Interacting risks in infrastructure, the built and natural environments

Led by WSP

This project assesses a key evidence gap from the CCRA2 Evidence Report in understanding how climate change affects the interaction of risks across the infrastructure, built environment and natural environment sectors. The project has created 12 interlinked systems maps showing principal interactions within and between the three sectors. Developed alongside the 12 systems maps is an interactive online tool, which visualises a single (combined) ‘mega map’ where users can select different climate inputs to identify pathways that are of interest.


Front cover of A consistent set of Socioeconomic Dimensions for CCRA3

A consistent set of socioeconomic dimensions for CCRA3

Led by Cambridge Econometrics

This report has produced consistent socioeconomic datasets to be used by the CCRA research teams and authors. The socioeconomic metrics considered are population, GDP, GVA, employment, labour productivity, land use, R&D expenditure, energy generation by technology and household size.
