Socio-economic impacts of marine litter for remote oceanic islands: The case of the Azores
2020
Rodríguez, Yasmina | Ressurreição, Adriana | Pham, Christopher K.
Marine litter is present throughout the world's oceans, representing a significant threat to marine ecosystems. While most efforts have focused on assessing ecological impacts, information on the socio-economic dimension of marine litter is scarce. Here we provide a detailed assessment of the direct economic costs of marine litter for a remote region of the North-East Atlantic, the Azores archipelago. Face-to-face interviews were performed to quantify and characterise the costs of marine litter-related incidents and coastal clean-ups to 259 sea-users and 21 local authorities, respectively. Overall, marine litter pollution was estimated to cost a total of €710,698 (±195,181, SD) per year, which is the equivalent to 0.02% of the Gross Domestic Product of the Azores archipelago. Our results demonstrate that marine litter creates costs and inconveniences for a range of stakeholders engaged in marine activities and also increases the waste clean-up budgets of small communities living on remote islands.
