Ground-truthing social vulnerability indices of Alaska fishing communities 5
Lavoie, Anna; Sparks, Kim; Kasperski, Stephen; Himes-cornell, Amber; Hoelting, Kristin; Maguire, Conor.
Community vulnerability is increasingly evaluated through quantitative social indices, typically developed using secondary data sources rather than primary data collection. It is necessary to understand the validity of these indices if they will be used to inform policy and decision making. This paper presents a ground-truthing effort to validate quantitative indices that characterize the well-being of Alaska fishing communities. We utilized ethnographic data collected from 13 representative communities and a capital assets framework to ground-truth the indices, in which qualitative ranks of vulnerability were compared against quantitative indices. The majority (73.8%) of ranks were in complete or moderate agreement and the results indicate that most of...

Local fishermen's perceptions of the usefulness of artificial reef ecosystem services in Portugal 5
Ramos, Jorge; Lino, Pedro G.; Himes-cornell, Amber; Santos, Miguel N..
Proponents of artificial reef (AR) deployment are often motivated by the usefulness of such structures. The usefulness of ARs is related to their capability of providing ecosystem services/additional functions. We present two distinct Portuguese AR case studies: (1) The Nazare reef off the central coast of Portugal and (2) the Oura reef off the Algarve coast. Semi-structured interviews were conducted with local fishermen in the fishing towns of Nazare and Quarteira pre-and post-AR deployment. The main focus of the interviews was to understand fishermen's perception of AR usefulness (or lack thereof) in terms of nine ecosystem services/additional functions potentially provided by the ARs. We tested the null hypothesis that ARs do not provide additional...

Mangrove Ecosystem Service Values and Methodological Approaches to Valuation: Where Do We Stand? 5
Himes-cornell, Amber; Grose, Susan O.; Pendleton, Linwood.
Mangroves, seagrass meadows, and salt marshes, collectively termed “Blue Forests,” are counted among the most valuable and productive coastal ecosystems on the planet. A recent literature review of the Blue Forest valuation research identified mangroves as the most frequently analyzed of these ecosystems, yet the literature demonstrates several deficits in terms of geographic location of studies, methods used to value the services, and most notably, a lack of valuation for cultural services. To better understand this, we analyzed the studies dealing specifically with mangroves from the original literature review to quantify what has been valued, where, by which methods, and the variation in the published values. We then use this information to synthesize...
