Non-market valuation of beach quality: Using spatial hedonic price modeling in Hilton Head Island, SC
ارزیابی غیر بازاری از کیفیت ساحل: استفاده از مدل سازی قیمت هیدونیک فضایی در جزیره هیلتون SC-2020 Climate change has been impacting beach quality negatively for years. The gradual increase in sea level has been
slowly diminishing the Atlantic coastline by eroding beaches and worsening coastal flooding. Narrowing beach
width, one of the most important attributes of beach quality, has been a major concern for policy makers, local
residents and visitors as lower beach quality has environmental and economic consequences. Filling the beaches
with sand under beach replenishment projects has been widely used to treat this problem. The purpose of this
paper is to estimate the economic value of beach width using the past residential property prices in Hilton Head
Island, SC. Spatial error hedonic price method was adopted to account for spatial dependency among error terms.
The results of this study show that beach width has significant influence on the values of neighboring properties
that are located within 633 feet of the shoreline. An additional foot of beach width would add as much as $3,012
to the value of an oceanfront residential property. Without an accurate estimation of the economic value of beach
width, cost-benefit analyses of beach nourishment and other shoreline management projects would be
incomplete. Keywords: Hedonic price method | Beach width | Beach replenishment | Beach nourishment | Spatial error model |

Public perceptions of beach nourishment and conflict management strategies: A case study of Portonovo Bay in the Adriatic Italian Coast
درک عمومی از تغذیه ساحلی و استراتژی های مدیریت تعارض: مطالعه موردی از خلیج Portonovo در ساحل ایتالیایی دریای آدریاتیک-2016 Conflicting interests, goals, and value often shape the stakeholders’ positions concerning coastal erosion
management strategies. Analyses of stakeholders’ perceptions of beach nourishment and conflict management strategies are lacking. Since the involvement of key stakeholders is crucial to ensure successful
integrated coastal management, the aim of the current study was to investigate the stakeholders’ perceptions of beach nourishment and conflict management strategies in the community of the Portonovo Bay in
the Adriatic Italian coast. During 2013, detailed, semi-structured interviews were conducted with members of the community and stakeholders regarding beach nourishment and related conflict management
strategies at Portonovo Bay. The results revealed that respondents not only reported different perceptions,
values, and interests but also their main goals were dissimilar. We found polarized opinions concerning
antagonistic value systems shared by the participants, which were associated with quite opposed perceptions of existence and severity of the problem and efficacy and harmfulness of beach nourishment.
The perceptions of the respondents were categorized into two major categories that reflect two of the
philosophical views of the human-environment relationship: ecocentrism versus anthropocentrism. Four
categories of proposed conflict resolution strategies were identified: (a) information, (b) dialogue and
contact, (c) compromise, and (d) no solution. The adoption of a participatory approach and the implementation of conflict management skills and technique can be considered important elements of coastal
management.
