The development of local food markets has provided a critical economic opportunity for small farms in New England. The collapse of Gulf of Maine groundfish stocks has motivated an interest in developing similar marketing opportunities for wild-caught, locally abundant seafood. Institutions, particularly schools and colleges, have been identified as a strategic entry point in the supply chain for such products. However, there has been a dearth of research on this topic. We undertake a case study that evaluates purchases of local groundfish by schools and colleges in New England. First, we analyze recently developed secondary data to assess the propensity and frequency of local seafood purchases. We find that local seafood purchases by schools in New England are not widespread even among the subset of schools that are undertaking farm to school activities, and that schools that are purchasing local seafood are doing so infrequently. We also find that colleges have been more proactive in sourcing local seafood products. There is a high degree of state-level variation within New England, as institutions in states with relatively more prominent commercial fishing sectors are sourcing local seafood products to a relatively greater degree. Further, colleges explicitly expressed that technical assistance in sourcing sustainable seafood products would be most beneficial in regions where there was less available supply. Second, to draw further inferences about the sustainability of local seafood purchases, we report the results of seafood procurement procedures from New England colleges. We find that these colleges source a wide variety of local groundfish principally for on-campus dining and that they place high value on seafood certification schemes as guidance for making sustainable purchases. We conclude by reviewing how data collection methods for local agricultural markets could be modified with regard to seafood distribution systems.

当地食品市场的发展为新英格兰的小农场提供了重要的经济机会。缅因湾底栖鱼类资源的锐减,激发了人们对开发类似的营销机会的兴趣,这些机会来自当地丰富的野生捕捞海鲜。机构,特别是学校和学院,已被确定为此类产品供应链的战略切入点。然而,关于这一主题的研究一直缺乏。我们进行了一项案例研究,评估新英格兰学校和学院购买当地底栖鱼的情况。首先,我们分析了最近开发的二手数据,以评估当地海鲜购买的倾向和频率。我们发现,新英格兰地区的学校购买当地海鲜的情况并不普遍,即使是在那些开展农场到学校活动的学校中,购买当地海鲜的学校也很少这样做。我们还发现,大学在采购当地海鲜产品方面更加积极主动。在新英格兰,由于商业捕鱼业相对更突出的州的机构采购当地海产品的程度相对更大,因此州一级的差异很大。此外,各学院明确表示,在采购可持续海产品方面提供技术援助对供应较少的地区最为有利。其次,为了进一步推断当地海鲜采购的可持续性,我们报告了新英格兰大学海鲜采购程序的结果。我们发现,这些大学采购各种各样的当地底栖鱼,主要用于校园餐饮,他们高度重视海鲜认证计划,作为可持续采购的指导。最后,我们回顾了当地农业市场的数据收集方法如何在海鲜分销系统方面进行修改。这篇研究文章发表在海洋与沿海经济学杂志:https://cbe.miis.edu/joce/vol5/iss1/2上

Each year, millions of Americans visit beaches for recreation, resulting in significant social welfare benefits and economic activity. Considering the high use of coastal beaches for recreation, closures due to bacterial contamination have the potential to greatly impact coastal visitors and communities. We used readily-available information to develop two transferable models that, together, provide estimates for the value of a beach day as well as the lost value due to a beach closure. We modeled visitation for beaches in Barnstable, Massachusetts on Cape Cod through panel regressions to predict visitation by type of day, for the season, and for lost visits when a closure was posted. We used a meta-analysis of existing studies conducted throughout the United States to estimate a consumer surplus value of a beach visit of around $22 for our study area, accounting for water quality at beaches by using past closure history. We applied this value through a benefit transfer to estimate the value of a beach day, and combined it with lost town revenue from parking to estimate losses in the event of a closure. The results indicate a high value for beaches as a public resource and show significant losses to the town when beaches are closed due to an exceedance in bacterial concentrations.

每年,数以百万计的美国人到海滩休闲,产生了显著的社会福利效益和经济活动。考虑到海岸海滩的大量娱乐用途,由于细菌污染而关闭的海滩可能会对海岸游客和社区产生巨大影响。我们利用现成的信息开发了两个可转移的模型,它们一起提供了海滩日价值和海滩关闭造成的损失价值的估计。我们模拟了马萨诸塞州科德角巴恩斯特布尔海滩的访问量,通过面板回归来预测按日期、季节类型的访问量,以及公布关闭后失去的访问量。我们对美国各地进行的现有研究进行了荟萃分析,通过使用过去的关闭历史来考虑海滩的水质,估计我们研究区域的海滩访问的消费者剩余价值约为22美元。我们通过利益转移来应用这个值来估计海滩一天的价值,并将其与停车损失的城镇收入相结合来估计关闭事件的损失。结果表明,海滩作为一种公共资源具有很高的价值,并且由于细菌浓度超标而关闭海滩对城镇造成了重大损失。

The Application and Usefulness of Economic Analyses for Water Quality Management in Coastal Areas. 经济分析在沿海地区水质管理中的应用与作用。

In managing water quality in U.S. estuaries, as well as throughout ocean and coastal governance, there is an increasing call for economic research to communicate the values of environmental resources to local communities, policy makers, and other stakeholders. Watershed managers implement economic studies to: 1) better communicate the value of estuarine resources to the wider community, 2) determine the most cost-effective management actions, and 3) compare the costs and benefits of actions to improve water quality. In order to better understand how economic studies are applied and their usefulness in coastal management, we interviewed managers from six National Estuary Programs (NEPs) and two watershed organizations that have undertaken economic studies, focusing on the lessons learned from the use of those studies. Economic studies can provide insights to managers and stakeholders about the implications of management actions or lack of action. Although economic research can offer a common language and framework, estimating economic values of policy changes to estuaries is a complex process requiring careful implementation in terms of methodology and scale as well as in the presentation and application of findings (Pendleton 2010). The findings from our interviews highlight the utility and limitations of economic analyses for coastal management and may help coastal managers to determine the most appropriate economic approaches to suit their needs and to avoid some of the pitfalls faced by other managers in conducting and communicating economic analyses. Additionally, our findings may help economists understand the needs of estuary managers, and help them better provide economic research that can contribute effectively to coastal management.
