Towards this aim, understanding the complex relationships between coastal well-being and ecosystem services provides a foundation for a range of management and governance in- terventions. While these relationships are considered in a growing number of case-based studies, the complexity of these linkages has not been comprehensively assessed. We use a systematic review protocol of 50 articles published between 2008 and 2018 to assess the evidence about the interplay among coastal well-being and ecosystem services. We fnd that empirical research has fallen behind theoretical development in fve key areas: 1) geographic diversity; 2) disaggregated data; 3) temporal dynamics; 4) co-production, and; 5) uncertainty of outcomes. We highlight these gaps as frontiers for interdisciplinary coastal well-being and ecosystem service research. Together, the fve frontiers chart a potential new research agenda for coastal well-being and ecosystem services research, namely one that involves more cases and authors from the Global South, that explicitly ex- plores social differentiation and changes overtime, that is collaborative from the start, and that engages empirically with the complexity and uncertainty of well-being-ecosystem service interactions and their impli- cations for enhancing management. Our proposed agenda is vital to inform management that effectively supports the health and sustainability of coastal social-ecological systems. 1. Introduction Oceans cover more than 70% of the Earth’s surface. They regulate our climate and provide us with food, energy, transportation, sense of identity, spiritual and cultural values (Barbier, 2017). Oceans and coasts support the livelihoods of hundreds of millions of people and contribute more than 60% of the total economic value of the biosphere (Martinez et al., 2007). Yet, oceans are some of the most heavily impacted systems on the planet (Nicholls and Cazenave, 2010). Once vast and remote spaces, marine ecosystems are now under extraordinary anthropogenic pressure (Hughes et al., 2017). More than 40% of the world’s 7.5 billion people live within 200 km of the coast and this number is expected to rise (Neumann et al., 2015). Climate change, land-based pollution, un- sustainable resource extraction, and habitat degradation threaten ocean sustainability (Jacquet and Jackson, 2018). Interdisciplinary approaches and methods to engage coastal com- munities in management are urgently needed to address coastal change and associated uncertainty. Ecosystem services and well-being concepts are increasingly promoted as approaches for integrated coastal man- agement in response to these challenges (Abunge et al., 2013; Kittinger et al., 2014). Indeed, the United Nations’ Sustainable Development Goals (SDGs), including SDG 14 Life Below Water, aim to realize uni- versal social well-being (UN, 2015; Costanza et al., 2016). The proposed Decade for Ocean Science for Sustainable Development “will provide a unifying framework across the UN system to enable countries to achieve all of their ocean-related Agenda 2030 priorities …. [and] will have a signifcant impact on helping many countries to achieve the Sustainable Development Goals needed to support the health and well-being of their * Corresponding author.
