Combining participatory and socioeconomic approaches to map fishing effort in small-scale fisheries.
PLoS ONE, 2017 Mapping the spatial allocation of fishing effort while including key stakeholders in the decision making process is essential for effective fisheries management but is difficult to implement in complex small-scale fisheries that are diffuse, informal and

Fish grabbing: Weak governance and productive waters are targets for distant water fishing.
PLoS ONE, 2022 Distant water fishing occurs worldwide as foreign fleets fish in the exclusive economic zones (EEZs) of other states. We test the hypothesis that host state governance performance is an explanatory factor in observed distant water fishing effort using ...
