In this chapter, we present preliminary results of a model of an SES of Kamorta Island (henceforth referred to as the K-SES model) belonging to the Nicobar archipelago in the Bay of Bengal. It is one of the very few attempts to link input–output metabolic modelling with an agent-based land-use change model rooted in the complex adaptive system approach. The modelled system includes the island of Kamorta with its human population and the surrounding reefs and shallow waters.
