Silvofishery, a novel solution to reduce global warming impact on coastal marunda fisheries farming, North Jakarta, Indonesia

Abstract

Under the global warming era, the sea level rise had become a major threat to coastal fisheries farming in Marunda, North Jakarta. Those threats known as "Banjir Rob" (Rob Flood) had caused big lost and extreme change in environmental factors as well. Therefore, this research aims to assess the coastal ecosystem resiliencies and farmer community attitudes in order to formulate the most suitable silvofishery-based coastal management systems. The environmental parameters (PH, temperature, salinity) in pond were varied extremely, for instance pH ranged 6 - 8; temperature 31 �c_ 34�c and salinity 26 %0 - 50 %0. In RW 7, approximately 92% of respondents know the types and the benefits of the mangrove. In contrast, in RW 2 only 80% of respondents know the types and 44% know the benefits of the mangrove. By considering the threats and opportunities on Marunda .fisheries farming, several Silvofishery-based solutions have been formulated as follows: I.The trend of fisheries farming in Marunda should be shifted from mono to polyculture by stocking more diversified species (Epinephelus sp. , Scylla serrata, Tilapia niloticus, Pangasius sp. Pagellus sp. and Chana sp.) that more tolerant to the harsh environmental conditions 2. Mangrove planting targeting 5 species (Avicennia alba, Cerios tagal, Bruguiera gymnorhiza, Rhizopora apicula, Rhizopora mucronata) is highly recommended in RW 7 communities since publics were well prepared.
