Aportaciones desde la economía de la adaptación a la toma de decisiones sobre cambio climático: un ejemplo para la Comunidad Autónoma del País Vasco 31
Galarraga, Ibon; Oses, Nuria; Markandya, Anil; Chiabai, Aline; Khantun, Kaysara.
As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding. The values estimated for the Nervión river in the city of Amurrio (Álava) indicate that the average expected damage will increase in 15 per cent as a consequence of CC (from €56,097 to €64,451). For an extreme episode the total loss could increase to €20 million. The second framework is oriented towards the valuation of the...

Toward Operationalizing Resilience Concepts in Australian Marine Sectors Coping with Climate Change 7
Leith, Peat; Tasmanian Institute of Agriculture, University of Tasmania; Peat.Leith@utas.edu.au; Madin, Elizabeth M.; Department of Environmental Sciences, University of Technology Sydney; Dept. of Biological Sciences, Macquarie University ; dr.elizabeth.madin@gmail.com.
We seek to contribute to the scholarship on operationalizing resilience concepts via a working resilience indicator framework. Although it requires further refinement, this practical framework provides a useful baseline for generating awareness and understanding of the complexity and diversity of variables that impinge on resilience. It has potential value for the evaluation, benchmarking, monitoring, and reporting of marine system resilience. The necessity for such a framework is a consequence of the levels of complexity and uncertainty associated with climate change and other global change stressors in marine social-ecological systems, and the problems involved in assessing their resilience. There is a need for: (1) methodologies that bring together...

Global ensemble projections reveal trophic amplification of ocean biomass declines with climate change 5
Lotze, Heike K.; Tittensor, Derek P.; Bryndum-buchholz, Andrea; Eddy, Tyler D.; Cheung, William W. L.; Galbraith, Eric D.; Barange, Manuel; Barrier, Nicolas; Bianchi, Daniele; Blanchard, Julia L; Bopp, Laurent; Buchner, Matthias; Bulman, Catherine M.; Carozza, David A.; Christensen, Villy; Coll, Marta; Dunne, John P.; Fulton, Elizabeth A.; Jennings, Simon; Jones, Miranda C.; Mackinson, Steve; Maury, Olivier; Niiranen, Susa; Oliveros-ramos, Ricardo; Roy, Tilla; Fernandes, Jose A.; Schewe, Jacob; Shin, Yunne-jai; Silva, Tiago A. M.; Steenbeek, Jeroen; Stock, Charles A.; Verley, Philippe; Volkholz, Jan; Walker, Nicola D.; Worm, Boris.
While the physical dimensions of climate change are now routinely assessed through multimodel intercomparisons, projected impacts on the global ocean ecosystem generally rely on individual models with a specific set of assumptions. To address these single-model limitations, we present standardized ensemble projections from six global marine ecosystem models forced with two Earth system models and four emission scenarios with and without fishing. We derive average biomass trends and associated uncertainties across the marine food web. Without fishing, mean global animal biomass decreased by 5% (+/- 4% SD) under low emissions and 17% (+/- 11% SD) under high emissions by 2100, with an average 5% decline for every 1 degrees C of warming. Projected biomass...
