5 In line with the Monaco Declaration and in accordance with the wishes of Prince Albert II, an International workshop series - «Bridging the Gap between Ocean Acidification Impacts and Economic Valuation» - was launched by the Centre Scientifique de Monaco and the Environment Laboratories of the IAEA.

6 Three workshops have been organized since 2010 all gathering multidisciplinary international experts and have resulted in clear conclusions and recommendations for policy makers. In the first workshop (2010), for the first time, economists and scientists came together to open the lines of communication and foster cooperation and coordination. The second workshop (2012) focused on regional impacts of ocean acidification on fisheries and aquaculture. The third workshop (2015) deals with the socio-economic impacts of ocean acidification on coastal communities. x

13 The objective of the second international workshop on Bridging the Gap between Ocean Acidification Impacts and Economic Valuation was to assess ocean acidification impacts on fisheries and aquaculture resources in different regions of the world. The regions were artificial aggregations of the fishing areas defined by the Food and Agriculture Organization (FAO). Each region spanned multiple political, economic and ecological units.

14 GENERAL CONCLUSIONS Ocean acidification is a global issue directly caused by increased anthropogenic CO 2 emissions to the atmosphere. It is happening now and CO 2 absorbed by the oceans will continue to rise long after emissions are reduced. Some ocean areas such as upwelling waters (deep water drawn upwards as wind pushes surface water offshore), polar and sub-polar regions, and some coastal and estuarine waters are natural hot spots of special concern for ocean acidification. Coastal waters are subject to warming, low oxygen, high nutrients and pollution in addition to ocean acidification, exposing aquatic species and communities to multiple stressors. World capture fisheries and aquaculture generated about US$218 billion in This provides an estimated 4.3 billion people with at least 15% of their animal protein. Over the last 30 years world food production by aquaculture has expanded twelve-fold; representing nearly half of human seafood consumption. Dependence on marine protein is expected to continue to rise with increasing human population. Major fisheries and aquaculture often occur in areas sensitive to ocean acidification. This puts economies and livelihoods at risk, and requires consideration and action by policy makers. Research on valuable seafood species is limited. Studies indicate that some shellfish used in aquaculture may be vulnerable to ocean acidification. Much uncertainty remains concerning finfish.

15 RECOMMENDATIONS Mitigate the effects of ocean acidification by reducing emissions of atmospheric CO 2. Establish ad hoc coastal monitoring networks for standardized measurement of ocean acidification. Support research on valuable finfish, shrimp and other shellfish in high CO 2 conditions to enable socio-economic assessment of impacts on food security. Implement best practices and adaptive management of fisheries and aquaculture to increase ecological resilience of marine ecosystems. Increase the adaptive capacity of fishing communities through education about ocean acidification, and by training and support to diversify livelihoods where needed. Improve multi-stakeholder exchange of information and communication among parties (coastal communities, businesses, researchers, resource managers, international organizations and policy makers).

17 Ocean acidification and coastal communities This workshop focused on the socio-economic impacts of ocean acidification on coastal communities and discussions centered around three main topics: 1) coastal economic activities with an emphasis on fisheries, aquaculture and tourism; 2) modelling as a tool to evaluate bio-socio-economic impacts of ocean acidification; 3) potential measures to tackle ocean acidification including societal action and adaptation, governance and legislation options.

Local and national management Adaptive management to address complexity - Improve coastal ecosystem resilience through effective fisheries and aquaculture management - Build community resilience by

18 Local and national management Adaptive management to address complexity - Improve coastal ecosystem resilience through effective fisheries and aquaculture management - Build community resilience by supporting diversified coastal community economies - Explore innovative financing for adaptation - Build ecosystem resilience by reducing local stress factors and creating marine protected areas - Broaden opportunities for coastal communities by developing tourism attractions based on healthy reef systems

19 International policy Dynamic leadership to facilitate change - Work to achieve urgent reduction in CO2 emissions. - Place ocean acidification, along with other climate change drivers, as a high priority for more countries - Mainstream ocean acidification into global, regional and national policies - Foster public and private investment in social, economic and environmental capital in communities and regions considered most vulnerable - Make ocean acidification projects eligible to the Green Climate Fund

20 Fourth International Workshop Bridging the Gap between Ocean Acidification Impacts and Economic Valuation From Sciences to Solutions: Ocean acidification impacts on ecosystem services- Case studies on coral reefs A series of recommendations for policy makers were developed as a result of the first three workshops, including: reducing CO2 emissions as the first objective for a sustainable solution; reducing local threats and establishing marine protected areas; since adapting solutions (e.g. migration of populations, habitat restoration, coastal protection, changes craft practices) can be quite costly, preference should be given to encouraging mitigation solutions (reducing CO2 emissions) and including oceans in all international negotiations on climate change; increasing ecosystem and societal resilience through improved fisheries and aquaculture management practices; restoring fish stocks and biodiversity; empowering most vulnerable communities; searching for innovative sources of funding and including ocean acidification in the "green background climate"; promoting knowledge development, data collection platforms and information sharing; taking into account social aspects in the design of environmental solutions; promoting an interdisciplinary approach should be encouraged to be complementary to propose solutions to decision makers.

21 Fourth International Workshop Bridging the Gap between Ocean Acidification Impacts and Economic Valuation From Sciences to Solutions: Ocean acidification impacts on ecosystem services- Case studies on coral reefs The workshop will focus on the economically and socially important, but highly threatened, coral reefs ecosystems, using a case study approach. The goal of the workshop will be to determine mitigation and adaptation solutions to OA impacts on coral reef ecosystems and the services they render, at several levels: biochemical (e.g. geo-engineering), socio-economic (e.g. fisheries and selective aquaculture), legal (e.g. creation of protected areas and coral parks) and technological (e.g. development of sensors and monitoring systems). The six regions of reference are : 1. Red Sea 2. Indian Ocean and South-East Asia (e.g. Indonesia, Maldives, Micronesia, Seychelles, Mayotte, la Réunion, Madagascar) 3. French Pacific Islands: French Polynesia and New Caledonia 4. Australia: Great Barrier Reef 5. Caribbean and West Atlantic (e.g. Puerto Rico, Bahamas, Florida) 6. Non French Pacific Islands (e.g. Guam, Hawaii, Japan, Marshall Islands)

22 The workshop series is organized by the Monaco Scientific Centre (CSM) and the International Coordination Centre (OA- ICC) of the International Atomic Energy Agency (IAEA), with the support of:
