“…Estuaries provide several valuable ecosystem services such as protecting the coastline from erosion and wave action, fixing carbon, and recycling nutrients (Schaafsma and Turner, 2015). Estuarine pollution is particularly problematic as estuaries also provide essential habitat for many commercially and recreationally important species such as crabs, fish, and shellfish.…”

“…Although ecosystem services approaches are uniquely poised to inform management by eliciting the diverse values people hold for vulnerable coastal ecosystems, further research is warranted. The bulk of empirical marine ecosystem services assessments are in Western, developed countries 1 -mostly in Northern Europe and Northern America (Liquete et al, 2013;Schaafsma and Turner, 2015) -rather than the low-income coastal and island countries most vulnerable to environmental change. Work in the Pacific, in particular, is nascent (Folkersen, 2018;Laurans et al, 2013;Liquete et al, 2013).…”

What matters to whom and why? Understanding the importance of coastal ecosystem services in developing coastal communities

16Coastal ecosystems support the livelihoods and wellbeing of millions of people worldwide. 17However, the marine and terrestrial ecosystem services that coastal ecosystems provide are 18 particularly vulnerable to global environmental change, as are the coastal communities who directly depend on them. To navigate these changes and ensure the wellbeing of coastal communities, policy-makers must know which coastal ecosystem services matter to whom, and why. Yet, capturing people's perceptions of the importance of ecosystem services in developing coastal settings is challenging for several reasons. Firstly, coastal ecosystem services encompass both terrestrial and marine services across multiple categories (i.e. provisioning, supporting and cultural), that are difficult to value together. Secondly, widely used monetary valuation techniques are often inappropriate, because of culturally specific attributions of value, and the intangible nature of key cultural ecosystem services. Thirdly, people within communities may hold different ecosystem services values. In this paper, we examine how people ascribe and explain the importance of a range of marine and terrestrial ecosystem services in three coastal communities in Papua New Guinea. We use a mixedmethods approach that combines a non-monetary, ranking and rating assessment of multiple ecosystem services, with a socio-economic survey (N=139) and qualitative explanations of why ecosystem services matter. We find that people uniformly ascribe the most importance to marine and terrestrial provisioning services that directly support their livelihoods and material wellbeing. However, within communities, gender, wealth, and years of formal schooling do shape some differences in how people rate ecosystem services. In addition, although cultural ecosystem services were often rated lower, people emphasized that part of the reason they ranked provisioning services highly was because of their contribution to, for instance, bequest. People also expressed concern about more extractive ecosystem services, like coral materials and fuelwood, which tended to be used and rated slightly more important by women. We contend that integrated ecosystem services assessments that include narratives can capture the broad importance of a range of ecosystem services, alongside relational values and normative judgements. This exploratory approach is a useful step towards understanding the complexities of ecosystem services in coastal settings.

Introduction Humans have changed the climate, lands and seas, forests and coasts, in ways that may destabilize earth's key systems (Steffen et al., 2018(Steffen et al., , 2015. Marine and coastal ecosystems are already highly exploited and rapidly depleting. Already, half of all the world's salt marches, and approximately one third of mangroves, coral reefs, and sea-grasses have been lost or degraded (Barbier, 2017). Yet, responsibility for and v...

“…The value of carbon sequestration over the Mediterranean basin attributable to the biological pump has been recently estimated to be e281 million per year, equivalent to US$29 billion over the same period as this study (Melaku Canu et al, 2014). There are no other comparable values for offshore habitats as the majority of current blue carbon research is focused on coastal environments (Luisetti et al, 2013;Thomas, 2014;Schaafsma and Turner, 2015).…”

The Cost of Reducing the North Atlantic Ocean Biological Carbon Pump

To predict the impacts of climate change it is essential to understand how anthropogenic change alters the balance between atmosphere, ocean, and terrestrial reservoirs of carbon. It has been estimated that natural atmospheric concentrations of CO 2 are almost 200 ppm lower than they would be without the transport of organic material produced in the surface ocean to depth, an ecosystem service driven by mechanisms collectively referred to as the biological carbon pump. Here we quantify potential reductions in carbon sequestration fluxes in the North Atlantic Ocean through the biological carbon pump over the twenty-first century, using two independent biogeochemical models, driven by low and high IPCC AR5 carbon emission scenarios. The carbon flux at 1000 m (the depth at which it is assumed that carbon is sequestered) in the North Atlantic was estimated to decline between 27 and 43% by the end of the century, depending on the biogeochemical model and the emission scenario considered. In monetary terms, the value of this loss in carbon sequestration service in the North Atlantic was estimated to range between US$170-US$3000 billion in abatement (mitigation) costs and US$23-US$401 billion in social (adaptation) costs, over the twenty-first century. Our results challenge the frequent assumption that coastal habitats store more significant amounts of carbon and are under greater threat. We highlight the largely unrecognized economic importance of the natural, blue carbon sequestration service provided by the open ocean, which is predicted to undergo significant anthropogenic-driven change.
