 Emmanuel  A Sweke

Dr. Sweke is a research scientist at TAFIRI since 2007. He holds a PhD and Maters in Marine Bioresource and Environmental sciences from the Hokkaido University, Japan. He received his BSc. in Aquaculture from the Sokoine University of Agriculture, Tanzania, and Diploma in International Environmental Leadership from Center of Sustainability Science, Hokkaido University. His research interests and experience span much of aquatic ecology, resources conservation, assessment and management; aquaculture and environmental sustainability. He has published a number of scientific articles on freshwater protected areas, fish stock analysis and socio-ecology.

Social–Ecological Studies to Sustain Fisheries

The key rationale behind sustainability science is to understand the relationships between nature and human society to foster solutions to problems in the two components. Both natural and human drivers, and their interactions are known to cause pressures on marine ecosystems. The study is carried out in Akkeshi and Erimo in eastern Hokkaido, Japan. Fishers in these areas engage in a variety of fisheries and catch wide ranges of marine living species; about 40 and 20 species are landed in Akkeshi and Erimo, respectively. This work endeavored to fill in the knowledge gap on social–ecological systems, and foster future research directions, and facilitate formulation of sustainable fisheries management strategies in the areas.
