| ABSTRACT | The presentation is focused on showing the transference of knowledge on climate change from the scientist and expertise groups to the policymakers and society. As case of study, the Experts Group on Climate Change of Catalonia (GECCC) and the Catalan Advisory Council for Sustainable Development (CADS) are presented. The first one, created with the objective of prepare the First Report on Climate Change in Catalonia in 2005, has nowadays more than 60 members, that mainly come from universities and research centers, but also from the industry and economic activity. The CADS is a boundary organization between Science and Decision-Making. Attached to the Catalan Government, its 16 members are fully independent and a great part of them do research in Public Universities and/or Research Centers. The council was created in December 1998 and its mission is to contribute to the transition of Catalonia towards sustainable development. The members of CADS produce specific reports for the Catalan Government, or assess new procedures, strategies, plans or programs, and future legislation from the sustainability and climate change perspective. This is the case of the new Law on Climate Change. Due that sustainable development is a wide topic, the council has established some expert groups which gathers some of the most reputed experts in Catalonia (for instance on water, energy or circular economy). The cooperation with these experts allows the council to enrich their reflections to the government and, once again, contributes to bridge the gap between Science / Research and Policy-making. In the case of climate change, the CADS also have a very strong and fluent collaboration with the GECCC. With the aim of prepare the Third Report on Climate Change in Catalonia (TICCC), that will be present next autumn 2016, the Interdepartmental Commission on Climate Change of the Catalan Government decided to set up an interdisciplinary working group coordinated by the CADS and the GECCC. Following the IPCCC schema, this report is mainly organized into three major areas: 1) The scientific basis of climate change: past climate change trends in Catalonia, assessment of climate balances, regional carbon sinks, and future projections; 2) Impacts and vulnerability of the biophysical environment: climate-related risks, impacts and interactions with water resources, coastal and terrestrial ecosystems, soils, biodiversity and marine ecosystems; 3) Assessment of different policy and social domains, and economic sectors (agriculture, fisheries, livestock, energy, industry, waste, health, public perception, transport and mobility, land use, urban planning and housing, and mountain systems). This third part also includes relevant legal framework, societal perception and research, as well as an epilog with the main conclusions and the potential impacts in Catalonia of the COP-21 that was held in Paris. |
