@Ruddle has worked for years on management and knowledge systems in Pacific Island countries. He presented the gist of this work at a dialogue meeting (see attached - Annex 10) where he points out that the sustainability of Pacific resource management was intimately linked to input control (rather than effort control underlying many "Western" management systems). As social and cultural systems are progressively eroded so are the social norms enabling enforcement of such constraints. The big challenge is to develop new forms and values adapted to conditions today. One element will likely be (re)instating more effective ways of collective action that underpin change for sustainable living within planetary boundaries in conjunction with more social justice and equitable sharing. We are testing participatory methods of engagement as part of developing the small-scale fisheries academy, currently in Senegal, but hopefully elsewhere as well, to support empowerment of men and women in SSF to be able to play constructive roles in governance (be it forms of resource management or spatial planning processes). One early step can be seen here: https://www.mundusmaris.org/index.php/en/projects/proj2019/2291-2pilot-en
A lot of information can be found in this document published by the Sub Regional Fisheries Commission and based on more than 10 case studies around the world
I would caution that Co-management is a political construct. As such, reviews will quite possibly be slanted. I worked for more that 30 years in a variety of "Co-managed" fisheries. The reviews I have seen published tend to look at such things as empowerment of traditionally marginalized peoples, the appearance of coordinated management, etc. All valid. But, what is the condition of the resource? In my area, some salmon species declined to where they were listed under US's Endangered Species Act as Threatened. 25 years post-listing they are less abundant than an listing. I don't think this is "recovery". Yet, we have a well-working Co-managment system...... One must ask what the goals actually are and how success will be measured.
