Section 3.3, Chapter 3: Ocean case studies of socio-economic interest. Main result statement : The ocean is an integral part of the three pillars of sustainable development: environment, society and economy. Pressures on the ocean from climate change, pollution and overexploitation have increased in recent decades, posing unprecedented challenges, particularly for vulnerable communities such as large ocean island states, and these pressures need to be monitored. This study analyses time series of the key ocean variables sea surface temperature and chlorophyll-a in coastal reefs from two pilot regions in Fiji and New Caledonia. The in situ measurements represent the true local conditions, with coverage that is necessarily limited in time and space. Remote sensing data has a wide coverage but is necessarily limited in terms of resolution and accuracy in the coastal zone. Our analysis shows the advantage of using these complementary types of data for the same geographical areas at small spatial scales near the coast, and in particular for high frequencies and extreme events. We discuss the way forward for a co-constructed monitoring framework, drawing on current initiatives in Oceania, and recommend a methodology for using ocean data to support society and the economy. Co-construction with stakeholder involvement is paramount to this framework, including policy and decision makers, industry, scientists, local and indigenous organisations, government and non-government, all of whom need sound, multidisciplinary scientific advice, focused expertise and reliable evidence-based information to make informed and timely decisions on the right timescale. Such transdisciplinarity combines repertoires of scientific, traditional, administrative, technical and legal knowledge.
