“…Seagrass meadows provide important ecosystem services; primary production, nursery habitat for juveniles and human food from seagrass associated species (Ambo-Rappe et al, 2013; Buapet et al, 2013;Cullen-Unsworth et al, 2014;Jackson et al, 2015;Giakoumi et al, 2015). Others ecological services of seagrass are an estimated $1.9 trillion per year in the form of nutrient cycling and the significant enhancement of coral reef fish productivity and they provide a habitat for thousands of fish, birds and invertebrate species and are a major food source for the endangered dugong, manatee and green turtle (Waycott et al, 2009).…”

“…Local communities use them, too, for harvesting traditional medicines, fertilizers and for other aesthetic, instrumental, spiritual and religious purposes (Kenworthy et al, 2007) and key ecosystems supporting small-scale fisheries (de la Torre-Castroa et al, 2014), but in many areas, they are also threatening a way of life for those people closely associated with the system either directly or indirectly (Cullen- Unsworth et al, 2014), Therefore, better understanding of which ecosystem services areas sociated with specific seagrass genera and bioregions is important for improved coastal management and conservation (Nordlund et al, 2016).…”

Seagrass ecology contributes to the preservation of fish and other biota diversity and is also an important livelihood source for fishermen and local communities. The purpose of our research was (1) to determine the source of the threats toseagrass ecology and to the ecological services it provides for the sustainability of fish resources and (2) to determine the main indicators defining the conservation needs of seagrass in the study area. Data were collected through direct observation, questionnaires, interviews and discussions. Data for fish in the seagrass bed research sites were obtained using mini-trawlers belonging to local fishermen. All data were analyzed using descriptive statistical analyses. The results showed that seagrass beds play an important role in fish ecology and that local livelihoods were highly dependent on small-scale fishing. However, fishermen and local communities also constituted the two main threats to the preservation and sustainability of fish and other biota in the area. Our results found, too, that there is a scarcity of some types of biota: some fish species, mollusks, crabs, see-urchin and some types of sea cucumber were very difficult to find in the seagrass beds that were the focus of our study. Our conclusion is that, given the scarcity of fifteen species of fish, as well as of other biota and the lack of diversity in fish food in our study area, it is imperative that seagrass conservation becomes an important priority for conservation interventions.

“…Hal ini karena akses yang mudah dari para nelayan dan tidak terlalu banyak mengeluarkan bahan bakar dan hasil tangkapan yang baik. Menurut pendapat Cullen- Unsworth et al, (2013), menjelaskan bahwa lamun sebagai sistem sosial-ekologi yang dapat meningkatkan kesejahteraan masyarakat lokal. Interaksi antara ketergantungan antara masyarakat dengan adanya sumberdaya yang ada di ekosistem lamun dapat meningkatkan ketahanan pangan dan pendapatan masyarakat.…”

ABSTRAKEkosistem lamun merupakan salah satu bagian penting sebagai bagian penyusun kesatuan ekosistem pesisir bersama dengan mangrove dan terumbu karang. Secara spesifik, keterkaitan masyarakat sebagai pemanfaat sumberdaya pada ekosistem lamun belum banyak diungkapkan. Tujuan dari penelitian ini adalah untuk mengkaji keterkaitan sistem sosial-ekologi lamun berdasarkan hasil tangkapan sumberdaya ikan di lokasi penelitian dan mengestimasi besaran manfaat sumberdaya ikan kaitannya dengan jasa ekosistem lamun di lokasi penelitian. Penelitian ini dilakukan dengan pendekatan kualitatif dan kuantitatif. Data yang dibutuhkan adalah data primer dan sekunder. Data primer didapat dari wawancara dengan instrumen kuisioner dan pencatatan hasil tangkapan dan penjualan di pedagang pengepul. Analisis data penelitian ini menggunakan metode analisis diskriptif kualitatif dan net fishing revenue (NFR) yang diperoleh nelayan. Hasil penelitian menunjukkan bahwa terdapat keterkaitan sosial-ekologi dengan keberadaan ekosistem lamun yang dijadikan sebagai tempat penangkapan bagi perikanan skala kecil yang bisa berkontribusi dalam ketahanan pangan dan sebagai mata pencaharian nelayan di desa tersebut. Manfaat yang didapat perikanan skala kecil dari keberadaan ekosistem lamun yaitu kemudahan akses bagi nelayan skala kecil dalam mencari ikan karena lokasinya yang dekat dengan pantai. Secara umum besaran manfaat dari fungsi ekosistem lamun sebagai jasa penyedia terlihat dari pendapatan per hari nelayan skala kecil diatas UMK Kabupaten Bintan yaitu Rp. 93,000,00. Dengan adanya keterkaitan sosial-ekologi lamun tersebut dapat dilakukan pertimbangan pengelolaan pesisir terpadu dengan pendekatan sosial-ekologi lamun di lokasi penelitian.

“…Seagrass meadows are equally important to the coastal seascape, with evidence now available of their global value to human wellbeing (Cullen- Unsworth et al 2014). Th ese extensive intertidal, subtidal and deepwater habitats in the tropics are important for their ecological functions and ecosystem services, such as their role in food web dynamics, seascape interactions and biogeochemical processes (Duarte 2002;Moberg and Ronnback 2003).…”

Ⅲ ABSTRACT: Th e fl ow of ecosystem services from coral reefs, seagrass meadows and mangrove forests sustains the livelihoods of billions of people worldwide. Faced with the global degradation of marine and coastal ecosystems, policy makers are increasingly focusing on ecosystem service valuation techniques to encourage conservation and sustainable use of marine resources. Here we provide a review and synthesis of the available information on economic valuation techniques as applied to tropical marine habitats. Our study demonstrates the high variability and lack of consistency in outcomes from these studies. We conclude that, if the concept of ecosystem goods and services is to make a positive contribution towards managing the impacts of humans on the environment, then economic valuation approaches must refl ect the inherent limitations of economic theory whilst emphasizing the complexity and heterogeneity of the natural environment and human decision making.
