Besides the erroneous assumption that tropical fisheries are open access, the cases demonstrate that pre-existing systems (1) are concerned with the community of fishers and ensuring community harmony and continuity; (2) involve flexible, multiple and overlapping rights adapted to changing needs and circumstances; (3) that fisheries are just one component of a community resource assemblage and depend on both the good management of linked upstream ecosystems and risk management to ensure balanced nutritional resources of the community; and (4) pre-existing systems are greatly affected by a constellation of interacting external pressures.

Originally published in 1990 Tropical Resources presents in-depth coverage of the extremely diverse tropical environments, the resources to be found within the region and their production, and ecological management. The book discusses economic geography and ways of utilizing available resources, including those of tropical forests, wildlife, tidal wetlands and the sea. The book also include chapters on the development and land use of protected areas, the ecological aspects of pasture resources; and the impacts of economic development and population damage. In addition, studies are offered on tropical soils, including their distribution properties and management and the ecological processes at work in tropical forests. For geographers, economists and policymakers, the book provides a wealth of information on tropical resources and their potential development.
