The hazards of coastal erosion in Central Java, Indonesia: An overview

摘要

As an archipelago country, Indonesian coastal areas are the most dynamic and strategic areas foruddevelopment as they provide many resources for human livelihood. At the same time, however, coastal areasudare also prone to environmental hazards such as erosion and sedimentation processes. Erosion along theudcoast may cause loss of coastal land and damage infrastructures and buildings. The Semarang City, TegaludRegency, and Demak Regency of the Central Java Province are especially vulnerable to coastal erosion.udThis paper examines both the phenomenon and mitigation of erosion hazards in Central Java. It was foundudthat in Semarang City, for the past 100 years coastal erosion has threatened facilities and land use along theudcoast causing extensive loss of coastal land. The local government has embarked on several mitigatingudmeasures including the construction of dykes and sea walls. Similarly, coastal erosion and abrasion haduddamaged tourism infrastructures and diminished the coastal land of the Tegal Regency since 1994. In Demakudit led to the relocation of settlement and damage of aquaculture. Given the significant role of the city ofudSemarang, Tegal and Demak in the ongoing development of Central Java the issues of coastal erosion shouldudhave garnered serious attention from local and provincial government. Needless to say, coordinationudbetween planning and implementation of mitigation measures need to be comprehensive and enhanced.
