Euro-limpacs Deliverables

ABSTRACT - DELIVERABLE 143

Report from National End users Meeting (UK)

As part of the commitment of the Project to increase understanding and awareness of the key science, policy and management issues relating to climate change effects on aquatic ecosystems, a one day meeting "Climate Change and Aquatic Ecosystems in Britain; science, policy and management" was held at University College London on May 16th, 2007 The purpose of the meeting was to (i) Review progress in modelling climate change and freshwater ecosystems in the UK; (ii) Present the interim results of current UK and EU-funded research on climate change, especially from the EU-Euro-limpacs, EU-CLIME and EU-PRINCE projects; (iii) Discuss the implications for the implementation in the UK of current EU policies on water quality and aquatic biodiversity (principally the Water Framework Directive and the Habitats Directive) and (iv) identify gaps in our understanding and assess priorities for future research. Presentations were given by scientists summarising work to date on climate change projections, impacts and modeling and management strategies. Additionally, representatives from key conservation and regulatory agencies as well as the water industry, highlighted key issues and concerns in the UK from an ecological and policy perspective.

These proceedings comprise a report of the meeting and include papers by speakers at the meeting. Battarbee and Kernan introduce Euro-limpacs and highlight the key issues being addressed by the Project. Steynor demonstrated how the latest UK climate change scenarios, UKCIP08 will provide greater clarity and quantification for decision making. Murphy et al. show how the relationship between flow and macro invertebrate communities is complicated by the range potential flow indices, time windows and the specific features of individual river sites. George exemplifies the effects that year to year variations in the weather have on the physical, chemical and biological characteristics of large lakes. Moss et al provide a prognosis for shallow lakes which outlines the likely effects of climate change and eutrophication and outlines approaches for addressing these. Evans et al. highlight issues affecting upland water quality, in particular climate change, acidity, nitrogen and water colour. Whitehead gives some examples of the types of catchment management and adaptation options that can be explored using modelling approaches. A management tool to integrate environmental, social and economic data for catchment management is described by Maltby et al. A conservation perspective is given by Clarke who identified a series of climate change adaptation strategies for freshwater habitats and how these may represent a shifting emphasis with regard to freshwater conservation A summary of a panel discussion held at the end of the meeting is also included together with a joint statement from the key conservation and regulatory organizations outlining their major concerns and highlighting gaps in current knowledge.
