海洋保护区在很大程度上已被证明是保护海洋生态系统的有效工具,而海洋保护区对渔业产生的社会经济效益仍在争论中。为了保护自然种群和生态系统,许多海洋保护区在允许进行潜在可持续活动的缓冲区内设立了禁捕区。缓冲区内的小规模渔业可以通过促进当地社会经济而非常有益。然而,在海洋保护区内成功管理可持续海洋保护区、确保养护和渔业目标并实现双赢的指导方针在很大程度上是不存在的。从同行评议的文献、灰色文献和访谈中,我们建立了一个独特的数据库,其中包含25个地中海海洋保护区的SSF的生态、社会和经济属性。利用随机森林和Boruta算法,我们确定了一组决定海洋保护区内ssf管理成功的属性。我们的研究表明,如果具备以下五个属性(即MPA的高执法、管理计划的存在、渔民参与MPA管理、渔民在MPA董事会的代表和促进可持续捕捞),鱼类种群会更健康,渔民收入更高,社会对管理实践的接受度也会提高。这些发现对地中海沿岸社区至关重要,因此他们可以实现保护目标,同时允许对渔业资源进行有利可图的开发。
Marine protected areas (MPAs) have largely proven to be effective tools for conserving marine ecosystem, while socio-economic benefits generated by MPAs to fisheries are still under debate. Many MPAs embed a no-take zone, aiming to preserve natural populations and ecosystems, within a buffer zone where potentially sustainable activities are allowed. Small-scale fisheries (SSF) within buffer zones can be highly beneficial by promoting local socio-economies. However, guidelines to successfully manage SSFs within MPAs, ensuring both conservation and fisheries goals, and reaching a win-win scenario, are largely unavailable. From the peer-reviewed literature, grey-literature and interviews, we assembled a unique database of ecological, social and economic attributes of SSF in 25 Mediterranean MPAs. Using random forest with Boruta algorithm we identified a set of attributes determining successful SSFs management within MPAs. We show that fish stocks are healthier, fishermen incomes are higher and the social acceptance of management practices is fostered if five attributes are present (i.e. high MPA enforcement, presence of a management plan, fishermen engagement in MPA management, fishermen representative in the MPA board, and promotion of sustainable fishing). These findings are pivotal to Mediterranean coastal communities so they can achieve conservation goals while allowing for profitable exploitation of fisheries resources.
