Introduction
Currently working on participatory methods to empower women and men in small-scale fisheries through the SSF Academy. Mundus maris is looking for collaboration to extend the field testing beyond Senegal to promote the implementation of the Voluntary Guidelines for Ensuring Sustainable SSF and the SDGs. Working concomitantly on the global challenges, incl. phasing out harmful subsidies, stopping transshipment, protecting biodiversity and bottom-up empowerment helps implementation gap reduction.

Chapter
Illegal, unreported and unregulated (IUU) fishing is a serious offence often occurring in conjunction with large-scale fraud, corruption and human rights and labour abuses as among cost-cutting mechanisms in a globalised market of fisheries products. These constitute threats to maritime security as they tend to threaten human communities and displa...
Chapter
We build on a basic understanding that change towards Blue Justice and responsive governance requires the evolution of perceptions and attitudes of small-scale fisheries and empowerment for collective action of the men and women in small-scale fisheries themselves. We briefly point to sources of evidence that show the role of small-scale fisheries...
