18 januari 2019 Workshop “Climate Change Impacts on Groundwater October 12th 2011, Warsaw Groundwater aspects in the Guidance No.24 on River Basin Management in a Changing Climate (Klaus Hinsby/Hans Peter Broers/Ronald Kozel/Elisabetta Prezioso) which issues which are not covered with respect to groundwater? What issues should be taken into account in RBMP’s Organizing team Hans Peter Broers (Eurogeosurveys) Elisabetta Preziosi (IRSA-CNR, Italy) Klaus Hinsby (Geus, Denmark) Ronald Kozel (Bafu, Switzerland) Sophie Vermooten (Deltares,the Netherlands)

Ad hoc task GW and CC Overall objective (WGC mandate) To make a WGC contribution to horizontal issues, specifically on Climate change effects on groundwater expected pressures and impacts consideration in RBMPs (make them climate resilient) input to SSG on Climate Change and Water. Activity on an ad-hoc basis need a previous approval by the Water Directors and discussions with other WGs where needed.

Structure of the activity One or two workshops (2011, 2012) 2011 workshop endorsed by Water Directors 2012 workshop decided after results of first workshop Interaction with CIS Expert Group on Climate Change and Water Bridge between science and policy Presentations of scientific results (e.g. Genesis, WATCH, Aquaterra) Presentations on policy requirements by MS Presentations on best practices in RBMP’s by MS Recommendations for RBMP’s Programme of measures Monitoring Protected areas Workshop reports with key issues and outcomes of the workshops discussed at the WGC meetings following the workshops.

18 januari 2019 Ad hoc task GW and CC (2) Pressures on groundwater systems tend to increase, Primary effects of climate change associated human induced changes of surface and subsurface water management (= secondary effects) Secondary impacts of are expected to have the largest short-term effects on groundwater resources. increase of water demands and abstractions of groundwater for irrigation Land use may affect groundwater recharge and quality (e.g. biofuels)

Goals of the first workshop Aim: collect existing information and establish the knowledge base Policy requirements and knowledge gaps of the member states first step taking into consideration the guidance document 'River basin management in a changing climate'. Best practices in member states Inputs from scientific results of FPVII research projects Genesis, WATCH, Aquaterra national research projects which address the pressures and impacts of CC on groundwater The workshop will be used to share information and exchange views between member states and stakeholders aims to identify what the needs are for future work in CC and groundwater, both from policy and scientific perspective

Second workshop 2012 Aim: to make recommendations for climate resilient river basin management plans Recommendations on: programme of measures monitoring setup management of protected areas, both drinking water protected areas and protected nature reserves with groundwater dependent ecosystems. Needs authorisation of Water Directors

Meeting program of today First session: demands of the member states for having CC well incorporated in the 2nd and 3rd River Basin Management Plans Second session: presenting knowledge that is currently available among scientists in Europe Europe wide CC aspects of groundwater: Case studies on CC and groundwater in EU member states Third session: wrap-up discussion how to match knowledge and demands, and make plans for a follow-up.
