Adaptive strategies to Mitigate the
Impacts of Climate Change on
European Freshwater Ecosystems
Martin Kernan
Environmental Change Research Centre
University College London
Collaborative large-scale integrating project
Started: Feb 1st 2010
Duration: 4 years
Consortium of 25 partners (Europe, Canada & Australia)
NCCARF Climate Adaptation Futures Conference – Gold Coast 29 June – 1 July 2010
“The REFRESH programme is concerned with the development of a system
that will enable water managers to design cost-effective restoration
programmes for freshwater ecosystems at the local and catchment scales
that account for the expected future impacts of climate change and land-use
change in the context of the Water Framework and Habitats Directives”
“At its centre is a process-based evaluation of the specific adaptive measures that
might be taken at these different scales to minimise the expected adverse
consequences of climate change on freshwater quantity, quality and biodiversity.”

Understanding how the functioning of freshwater ecosystems is affected by climate
change
While earlier studies on climate change, including Euro-limpacs, focused on trophic
structure, relatively little is known about how climate change affects ecosystem
functioning. Controlling ecosystem functioning is at the heart of adaptive
management

To understand better the processes and effects of
multiple stress induced by climate/global change upon

this to identify adaptive management measures.

THRESHOLDS & REFERENCE
CONDITIONS

INDICATORS
Identify key effect parameters
(indicators) for climate change
in streams
What are temperature, flooding and nutrient
loading thresholds for riparian wetland key
functions and biodiversity? Can we define
reference conditions?
Which ecological response
variables can be used as
indicators for wetland key
functions and biodiversity?
Tools for vulnerability
assessment?
Guidelines on thresholds for temperature,
water level, salinity, nutrients and organic
matter in European lakes – identification of
reference conditions with a flexible, change

series datasets;

New indicators of functional response, tools for assessing vulnerability and
dynamic reference conditions
In REFRESH we will develop a new set of system indicators for freshwaters
focusing essentially on ecological indicators sensitive to the functional
response of rivers, lakes and wetlands to changes in temperature, flow/waterlevel and nutrient/organic matter loading. We will also develop new tools for
assessing vulnerability to climate change which take into account both site
specific and landscape (e.g. associated with connectivity, dispersal migration)
scale threats. We will examine how the concept of a dynamic reference
condition can be built into WFD and HD methodologies.

models… robust simulations of future water quantity,
quality and ecology at the catchment scale”
Objectives – better:

adaptation and cost effective restoration at local and
catchment scales

NCCARF Climate Adaptation Futures Conference – Gold Coast 29 June – 1 July 2010
OBJECTIVES
• To discover what
anthropogenic practices
compromise water quality
and/or environmental quality
in selected European
catchments
• To find cost-effective means
of mitigating climate-change
induced damage to water
quality and consider
reinstatement possibilities
• To assess whether these
compliance costs are
proportionate
• To assess whether
compliance delivers
changes in the values of
other ecosystem services
