Indonesia is known to be the largest archipelago country with more than 17.000 islands and the third biggest population number in the world. Indonesia is also laid in the ring of fire of the world, making more complex and even high in biodiversity which is the 2nd mega biodiversity after Brazil. With its long of coastal line reaching up to 99,093 km (Geospatial Information Agency, GIA) and 6.315.222 km2 of total seawater area, therefore, it is necessary to wisely manage the marine and coastal resources.
Indonesian coastal area is commonly inhabitant, which more than 300 Indonesian tribes live upon the area. Therefore, empowering of the coastal people should be taken into account for coastal and marine management. Natural changes have been widely occurred across the coastal line, converting mangrove and seagrass ecosystem into maricultures such as shrimp and fish ponds, recreational area, ports and else, which effectively change other ecosystem such as coral reefs. It has been known that those three ecosystems are well contributing in declining the global warming by increasing their ability as part of blue carbon storage, which related to the Indonesian government decree, implementing Sustainable Development Goals No. 14 to reduce as much as 29% of its emission gas by year 2030. Therefore, it is necessary to elucidate any potential engineering on restoring of the coastal ecosystems to reduce the climate change effects.
However, natural disasters affected by the ring of fire facts should be taken for deeply consideration in order to lessen damage which are commonly occur across Indonesia. In year 2018, at least 3 major natural disasters occurred, Lombok, Palu and Sunda Strait. It is aware that policies to respond to natural disasters in Indonesia are still in an early stage of being developed, need to develop strategies to deal with each of these different types of disasters.
This International Conference on Marine and Coastal Sciences held then, hence, to gather all many aspects related to marine and coastal study, function and uses for their benefits to humankind. We are expecting the conference will produce not only papers but also some remarks which necessary help policy makers.
