This report reviews approaches to costal management and community management in Malaysia, Vietnam, Cambodia and Thailand. It includes the case study on fisheries management in Thailand. Malaysia is the only one country with administration of coastal zone management by the federal Government and is strongest in surveillance and enforcement but lacks community based management. Community management in Vietnam established from community needs that they want to protected their resource and also had community traditions to supported resource management. Cambodia is very young in coastal management and almost of aquatic policy is focused on fresh water because close to 75 percent of aquatic protein come from the Tonle Sap and Mekong rivers. Thailand has decentralized fiscal responsibility to the local level for the collection of taxes and administration of funds. Fisheries communities have the right to manage their resources; an approach which was promoted by the Department of Fisheries. With respect to fisheries management, Thailand faces challenges of overexploitation of the resources and a lack of real data on the number of fishing gears; both of which must be addressed so as to allow effective fisheries management.
