Opportunities and constraints to urban aquaculture, with a focus on South and Southeast Asia.

Urban Farm DB summary

A review chapter surveys the concept, opportunities and constraints of urban aquaculture in South and Southeast Asia (SSEA), using the "extended metropolitan region" (EMR) and "waste economy" models to outline three development trajectories: opportunistic development within a changing aquatic landscape as urbanization proceeds, continuation of existing aquaculture in modified form as urbanization occurs around it, and strategic siting of new enterprises to exploit resources such as nutrients, markets or information. Urban aquaculture is described as providing benefits at household, local and municipal levels including waste disposal, food production, flood control, employment, environmental quality and recreation, while constraints include loss of suitable physical locations, changes in waste disposal practices, shifting attitudes and demand as urban areas grow more affluent, and vulnerability to contamination and theft due to the openness of aquatic systems.
