An increasing portion of the world's population and economic activity is located on lands adjacent to coastal waters. The result is ever increasing demands on the coastal resources, leading to increasing conflicts among uses and users and to decreased capacity of the resources to provide desired products and services. The study team carried out three analytical tasks. The first was to trace explicitly the evolution of the mix of uses of the bay over time, and the factors responsible therefore. The second was to analyze alternative futures to shed light on the net benefits to society of alternative management strategies. The third was to analyze existing institutional arrangements for decision-making for the Bay. Topics: Context and foci of study; Disposal of solid wastes; Living marine resources; Marine transport; Disposal of liquid wastes; Water-based recreation; Formulationn of the analysis; Estimating benefits implications for management to Tokyo Bay.
