SUMUSANO: Sustainable multi-use of ocean areas in South Africa and Norway

Coexistence in marine areas involves using the same ocean space for several purposes — including fisheries, aquaculture, shipping, tourism, and energy production — while safeguarding the environment and the interests of different user groups. As activity in coastal areas increases, so does the pressure on marine ecosystems, highlighting the need for knowledge that supports sustainable multi‑use.

SUMUSANO (Sustainable Multi‑use of Ocean Areas in South Africa and Norway) examines how aquaculture and the harvesting of low‑trophic marine resources can be integrated into shared marine spaces. The project focuses on two case areas: Saldanha Bay in South Africa and fjords in Møre og Romsdal, Norway. In Norway, the project studies sustainable fishing of red sea cucumber and great scallop using new technologies, while in South Africa, it explores opportunities for expanding mussel farming.

The research is interdisciplinary, assessing biological, ecological, and socio‑economic impacts — including effects on local communities and quality of life. Building on long‑standing marine cooperation between Norway and South Africa, the project brings together research institutions and industry partners from both countries.

The goal is to generate knowledge that supports sustainable, responsible, and lasting multi‑use of marine areas.
