“…Attitudes toward mangrove conservation and restoration also vary with the socio-demographic background of the respondents, i.e., gender (Rönnbäck et al, 2007;Badola et al, 2012), education level, awareness of mangrove loss and provided ES (Badola et al, 2012;Rahman and Asmawi, 2016;Roy, 2016). In this context, a higher level of education seems to be related to a higher awareness of conservation issues (Badola et al, 2012).…”

Public acceptability is a standard element on the list of potential constraints on research and deployment of ocean-based carbon dioxide removal (CDR). We outline past work on the public perceptions and acceptability of ocean-based CDR among laypersons covering the main developments over the past 15 years. We compare and synthesize insights from two distinct strands of literature – one on climate engineering approaches and the other on coastal ecosystem management or blue carbon approaches. We also draw conclusions from studies on land-based CDR for emerging ocean-based approaches. Main determinants of perceptions identified in the past are controllability, environmental impacts, containment, permanence of carbon storage, risks and benefits for the local population as well as to which degree an approach is perceived as natural or engineered. We highlight how these aspects may influence perceptions and acceptability of ocean-based CDR approaches which have not yet been on the agenda of perceptions research. Even though ocean-based CDR approaches cannot be neatly divided into categories, the public's tendency to favor approaches perceived more as natural over approaches perceived more as engineering could result in a dilemma between approaches with possibly high carbon sequestration potential but low levels of acceptability and approaches with possibly low sequestration potential but high levels of acceptability. To effectively work toward achieving net-zero carbon emissions by mid-century, however, we need to bridge the gap between natural and engineering-type approaches, also in research, to come up with a broad portfolio of CDR options to complement classic mitigation and adaptation measures.

“…Widiastuti et al (2016) mengungkapkan bahwa penggalian pasir di pesisir pantai, penebangan mangrove untuk kayu bakar dan pemukiman, serta rendahnya kesadaran masyarakat akan nilai penting ekosistem mangrove mengakibatkan sejumlah masalah ekonomi seperti yang terjadi di pesisir Kabupaten Merauke. Rahman and Asmawi (2016) juga mengemukakan hal serupa, yaitu bahwa sejak tahun 1980 jumlah mangrove di Malaysia semakin menurun yang mana utamanya disebabkan oleh praktik budi daya perikanan.…”

Pada tahun 1980an, Pulau Tanakeke memiliki kawasan ekosistem mangrove seluas kurang lebih 1.770 hektar. Namun, dalam kurun 1980an-2000an, luasan tersebut berkurang hingga 60 persen akibat dari pemanfaatan yang tidak terkendali oleh masyarakat sehingga terjadi perubahan lingkungan. Tulisan ini bertujuan mengkaji posisi sumber daya mangrove terhadap pengelolaan saat ini dengan mengestimasi nilai manfaat dan kerugian yang diterima masyarakat dari adanya pemanfaatan mangrove. Pengumpulan data primer dilakukan melalui metode survei dengan 40 responden pemanfaat mangrove. Analisis data menggunakan teknik valuasi ekonomi sumber daya alam dan lingkungan. Hasil analisis yang diperoleh menunjukkan bahwa nilai manfaat ekonomi ekosistem mangrove masih lebih besar dibandingkan dengan nilai kerugian yang timbul. Hasil analisis tersebut berimplikasi pada dua hal: 1) yaitu di satu sisi membuktikan bahwa ekosistem mangrove di Pulau Tanakeke memberikan kontribusi ekonomi yang cukup besar bagi masyarakat, 2) tetapi di sisi lain, nilai manfaat yang cukup besar tersebut dapat menjadi insentif bagi masyarakat untuk semakin ekspansif mengeksploitasi ekosistem mangrove sehingga dapat menjadi peluang ancaman bagi kelestarian ekosistem mangrove di Pulau Tanakeke apabila tidak dikelola dengan seksama.Title: Analysis of Benefits and Losses Value of Mangrove Ecosystem Uses in Tanakeke Island, South SulawesiIn the 1980s, Tanakeke Island had around 1,770 hectares of mangrove area. However, within a period of time 1980s-2000s, this area has reduced nearly 60 percent due to uncontrolled utilization by community resulting in environmental changes. This study aims to examine the position of mangrove resource towards existing management by estimating benefits and losses of mangrove utilization. Primary data were collected through a survey from 40 respondents of mangrove beneficiaries. Data were analysed using the resource and enviromental economic valuation techniques. The results indicate that the total economic value of mangrove ecosystem is greater than the losses value. This finding led to two implications: on one side, it is proved that the mangrove ecosystem in Tanakeke Island gives economic contribution in a considerable amount to the community. However, on the other side, this high value of benefits leads to an increasing exploitation of the mangrove ecosystem. Therefore, this condition could be a threat to the sustainability of mangrove ecosystem in Tanakeke Island if it is not managed carefully

“…If such degradation continues, mangroves may disappear in the next 100 years [ 21 ]. This degradation is triggered by multiple factors, such as urban development, industrialization, agricultural land expansion, timber and charcoal production, and shrimp farming [ 16 , 20 , 22 , 23 ]. In Indonesia, Thailand, and Malaysia, the loss of mangrove forests is triggered by the conversion of land to aquaculture, agriculture, and salt production [ 23 , 24 ].…”

Despite all efforts and massive investments, the restoration of mangroves has not always been successful. One critical reason for this failure is the vulnerability of young mangroves, which cannot grow because of hydrodynamic disturbances in the shallow coastal water. For a comprehensive study bridging ecological and engineering principles, a portable community-based reef is proposed to shield mangroves from waves during the early stages of their growth. A series of field observations were conducted on Amami Oshima Island (Japan), to observe the growth of young mangroves and their survival rate under moderate wave conditions. The evolution of young mangroves was also observed in the laboratory under a controlled indoor environment. At the research site, it was confirmed that, after six months of germination, young mangroves could withstand normal high waves. Laboratory-grown plants were lower in height and had fewer leaves compared with the native mangroves on Amami. Based on these results, an economical reef system was designed. For this purpose, the Ahrens formula for the design of a low-crested reef breakwater was revisited. The results showed that a 50-cm-high reef constructed with 15-kg stones can protect mangroves that are a few months old and effectively promote early mangrove growth.
