  Citation × Citation Citation Abstract Copy Title: A Proposed Framework for Identifying and Evaluating Ecosystem Service Tradeoffs for Marine Protected Area Planning Author: Harte, Michael, Heppell, Selina, Rosenberger, Randall, Sylvia, Gil Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management indicators tied to outcomes described in management plans or on the achievement of a single objective such as an increase in the size or number of older, more fecund female fish in a protected area. These approaches, however, fail to capture the dynamic complexity of social, cultural, economic and ecological processes, uncertainty, and tradeoffs associated with the establishment and operation of marine protected areas. Moreover, there is usually little recognition of local coastal communities, including fishing communities, and the values they hold in the evaluation of the relative benefits and costs of marine protected areas. We describe a framework for evaluating and assessing economic and ecosystem tradeoffs associated with marine protected areas and other forms of marine spatial planning. This framework integrates biophysical data and community-based social and economic evaluation methods. It identifies ecosystem services, their benefits and associated uncertainties in assessing the economic and social tradeoffs associated with changes in the use of the marine environment.

  Citation × Citation Citation Abstract Copy Title: An Impact and Management Study of Taiwanese Artificial Reef Deployment Author: Guinea, Estuardo, Kuo, Heng Hung, Chuang, Ching-Ta For the past decades, around 20% of the natural coral reefs were lost and > 20% more is currently deteriorating. Due to the recognition of positive impact to fishery resources enhancement by artificial reefs (ARs) deployment, Taiwanese government has started deploying ARs as a measure to improve the environment of fishing grounds since 1974. At present, there are 88 ARs deployment areas that have been established in Taiwan, which account for more than 180,000 sets of fishing grounds. However, fisheries enhancement is not the unique purpose of ARs deployment, it also include marine ecotourism as well as protection or restoration of certain habitats. Due to the nature of public goods, this results in dispute about cost and effectiveness of ARs deployment. This study analyzed the experience of Taiwan throughout the four decades of ARs deployment, and examined the value of ARs and the mechanism of self governance. A questionnaire was designed to explore the perception on ARs of different stakeholders, and results show a certain level of achieving fisheries enhancement objectives. Increased incidences of conflicts upon territories of ARs fishing grounds among stakeholders were observed. It also implied that cooperatives of fishermen associations and community are essential in the management stage of planning ARs deployment. Based on Taiwanese experience, effective ARs should take into account all variables including reef design, site selection, depth, materials etc. It is also recommended that in the process of ARs deployment, one can not take the current economic benefit as the only criterion; decision-makers should also consider the impacts on the natural environment, the efficient use of resources, as well as humanities and social aspects.
