Industrial Ecology is an operational concept for new capacity building in the field of Sustainable Development. Thus, projects of Industrial Ecology, like the ones enhanced in the University of South Pacific, are part of the new paradigm of sustainable production and consumption. The specific issue as the relevant scales and the spatial constraints of Small Island Developing States (SIDS) introduces a different point of view for the Material Flow Analysis tools. Hence, Industrial Ecology associated with a territorial governance strategy suggests a key lecture of industrial clusters, trade channels and sustainable development in the context of SIDS.
