“…Present day the study on the role of coastal vegetation (i.e. seagrass, salt marsh, seaweed bed, mangrove) to combat climate change by carbon dioxide mitigation has been increasing (Chmura et al 2003;Duarte et al 2005;Donato et al 2011;Sondak and Chung 2015;Sondak et al 2017). Mangrove plays an important role in carbon fixation that can help improve the capacity to absorb atmospheric CO2 by sequester through photosynthesis.…”

Abstract. Sondak CFA, Kaligis EY, Bara RA. 2019. Economic valuation of Lansa Mangrove Forest, North Sulawesi, Indonesia. Biodiversitas 20: 978-986. Mangrove forest gives many benefits and services to human and environment. Even though it contributes many benefits and services, coastal ecosystems threatened as one of the most critical ecosystems in the world. The study aims to estimate the economic value of ecosystem services provided by Lansa mangrove forest, Wori Sub-district, North Minahasa District, North Sulawesi Province, Indonesia. Here, we describe the use value (direct and indirect value) and non-use value (option and existence value), and emphasize the components of ecosystem services fish resources, firewood, coastal protection, biodiversity, carbon (C) removal and mangrove sustainability because these directly influence human welfare. Their market price calculated fish and C removal value. Coastal barrier and firewood were approached using the replacement cost method. Biodiversity value was calculated using Indonesia mangrove forest biodiversity value. Contingent Valuation method was used to find out people willing to pay for the sustainability of mangrove forest. Lansa mangrove forest total economic value (TEV) was IDR 4,431,197,603 or equal to US$ 305,600 (US$ 1,959 ha-1). The success of this mangrove valuation has potentially large implications for future policy-making of its’ ecosystem service values.

“…This can be achieved, for instance, through the use of seaweed biomass as biofuel directly replacing fossil fuels (e.g., Kraan, 2013;Chen et al, 2015), and/or replacing food or feed production systems with intense CO 2 emission footprints by seaweed-based food systems, which have much lower lifecycle CO 2 emission (Fry et al, 2012). Indeed, a seaweed-based Blue Carbon program has been developed in Korea (Chung et al, 2013;Sondak and Chung, 2015), providing an initial step in this direction. Yet, Korea contributes only 6% of global seaweed aquaculture production (FAO, 2016b), so the development of seaweed farming as a Blue Carbon strategy for climate change mitigation would require that major producers, such as China accounting for more than half of the global seaweed aquaculture production, engage with this strategy.…”

Can Seaweed Farming Play a Role in Climate Change Mitigation and Adaptation?

et al. 2017

Seaweed aquaculture, the fastest-growing component of global food production, offers a slate of opportunities to mitigate, and adapt to climate change. Seaweed farms release carbon that maybe buried in sediments or exported to the deep sea, therefore acting as a CO 2 sink. The crop can also be used, in total or in part, for biofuel production, with a potential CO 2 mitigation capacity, in terms of avoided emissions from fossil fuels, of about 1,500 tons CO 2 km −2 year −1 . Seaweed aquaculture can also help reduce the emissions from agriculture, by improving soil quality substituting synthetic fertilizer and when included in cattle fed, lowering methane emissions from cattle. Seaweed aquaculture contributes to climate change adaptation by damping wave energy and protecting shorelines, and by elevating pH and supplying oxygen to the waters, thereby locally reducing the effects of ocean acidification and de-oxygenation. The scope to expand seaweed aquaculture is, however, limited by the availability of suitable areas and competition for suitable areas with other uses, engineering systems capable of coping with rough conditions offshore, and increasing market demand for seaweed products, among other factors. Despite these limitations, seaweed farming practices can be optimized to maximize climate benefits, which may, if economically compensated, improve the income of seaweed farmers.

“…Recently, seaweeds have been considered as contributors to coastal Bblue carbon^in mitigating CO 2 (Chung et al 2011(Chung et al , 2013Sondak and Chung 2015;Hill et al 2015;TrevathanTacket et al 2015) because they contribute to storage of carbon by sequestration of CO 2 from seawater through photosynthesis and use it to increase their biomass (autochthonous carbon) that can potentially be transferred and deposited to other coastal ecosystems or the deep sea benthos (allochthonous carbon). In order for seaweeds to make significant contributions to global carbon sequestration, they must either have the (2011) n/a not applicable capacity to directly store and accumulate carbon within their own habitat or transport biomass to receiver habitats where carbon can be effectively buried and organic material prevented from undergoing microbial mineralization (Hill et al 2015).…”

Seaweed aquaculture beds (SABs) that support the production of seaweed and their diverse products, cover extensive coastal areas, especially in the Asian-Pacific region, and provide many ecosystem services such as nutrient removal and CO 2 assimilation. The use of SABs in potential carbon dioxide (CO 2 ) mitigation efforts has been proposed with commercial seaweed production in China, India, Indonesia, Japan, Malaysia, Philippines, Republic of Korea, Thailand, and Vietnam, and is at a nascent stage in Australia and New Zealand. We attempted to consider the total annual potential of SABs to drawdown and fix anthropogenic CO 2 . In the last decade, seaweed production has increased tremendously in the Asian-Pacific region. In 2014, the total annual production of Asian-Pacific SABs surpassed 2.61 × 10 6 t dw. Total carbon accumulated annually was more than 0.78 × 10 6 t y −1 , equivalent to over 2.87 × 10 6 t CO 2 y −1 . By increasing the area available for SABs, biomass production, carbon accumulation, and CO 2 drawdown can be enhanced. The conversion of biomass to biofuel can reduce the use of fossil fuels and provide additional mitigation of CO 2 emissions. Contributions
