Updated COASTAL CONSERVATION AND SUSTAINABLE LIVELIHOODS THROUGH SEAWEED AQUACULTURE IN INDONESIA: A Guide for Buyers, Conservation Practitioners, and Farmers on Documents
Over one million coastal Indonesians engage in seaweed aquaculture, a unique and growing global industry for production of carrageenan and agar, direct consumption, and animal feeds, among other uses. Carrageenan and agar, refined from red seaweeds, are used as ‘texturizers’ or thickeners primarily within foods and cosmetics, but have growing utility within areas such as animal feeds and pharmaceuticals. Indonesian seaweed farming presents a significant economic opportunity with the potential to be managed in a more sustainable manner. The Nature Conservancy’s (The Conservancy’s) vision is for seaweed aquaculture to grow in harmony with marine conservation objectives, support livelihoods in coastal communities throughout Indonesia, and provide ecosystem services for habitat and nutrient bioremediation – to encourage increased sustainability through the three dimensions of economic, social, and environmental. In response to the rapidly growing global market for carrageenan seaweeds, the environmental challenges and opportunities of seaweed farming, and the essential livelihoods that seaweed farming currently provides in Indonesia, The Conservancy presents this seaweed aquaculture guide for seaweed purchasers, conservation organizations working in seaweed, and seaweed farmers in Indonesia that are seeking to reduce environmental impacts, and to encourage sustainable livelihoods1 by improving the value of farmed seaweed through better farming and post-harvesting practices. This guide is divided into four main parts: (1) an introduction providing pertinent background regarding Indonesia in the context of carrageenan seaweeds; (2) a guide for seaweed buyers seeking to increase the sustainability of their supply chains; (3) a guide for conservation practitioners working in seaweed aquaculture for environmental, economic, and social gain; and (4) an illustrated guide for farmers to improve seaweed farming practices.

Updated Seaweed Industry in China on Documents
China represents world seaweed industry and its development in terms of total cultivated production and consumption market. Fujian and Shandong provinces contribute 42% and 32% of the total annual cultivated seaweed. Among 7 main popular cultivated seaweed species in China, Kelp (Saccharina (Laminaria) Japonica) has been accounting for majority of the total annual production in China, 98% in 1950s and still 68% nearly 1.5
Kelp food consumption took 80-98% of annual cultivated kelp during 1950s-early 1990s. From mid of 1990s to mid of 2000s, alginates industry competed 60% cultivated kelp raw materials while other 40% went for food. After year of 2005, market demands for kelp food and aquaculture feed increased gradually and steadily, taking 60% and 20% respectively. Alginates industry in China has to invest abroad for outsourcing kelp raw
hina, 98% in 1950s and still 68% nearly 1.5

Updated Seaweed Industry in China on Documents
Seaweed industry in Norway needs to strategically figure out whether to export cultivated and harvested kelp raw materials to China for alginates and/or food industry, or, to cultivate, harvest and process it into kelp food and/or alginates in Norway first and then export it to China.

Posted Seaweed blue carbon: Ready? Or Not? on Documents
There is an urgent need to achieve the United Nations Sustainable Development Goals (SDGs). At the same time, greenhouse gasses (GHGs) that contribute to global warming must be reduced to avoid even more severe climate disruption. Macroalgal (seaweed) systems can help the world achieve the SDGs by producing food, other valuable products, livelihoods, and a number of ecological benefits. Seaweed systems may also be drawing down atmospheric carbon dioxide, an important GHG, under some conditions. However, the net impacts of seaweed systems on GHGs (“blue carbon”) depends on many context-specific, complex biogeochemical processes and have thus far been difficult to quantify. We engaged experts in a system mapping exercise to support decision-making in the context of the high levels of uncertainty associated with seaweed blue carbon. The conservation and restoration of seaweed stands appears to be a low-regrets intervention that would produce many benefits, including some carbon sequestration under some conditions, with low risk. Increasing the productivity of seaweed farms may have a similar benefit and risk profile. A large expansion of seaweed farming coupled with sinking the seaweed biomass could significantly increase carbon sequestration, but with relatively large social, economic, and ecological risks. Certain products made from seaweed that sequester carbon, replace GHG-intensive products, or suppress GHG emissions could enhance the climate and socioeconomic benefits of seaweed systems while also improving prospects for quantifying and verifying them. More research and interventions will likely be necessary for such products to scale. A portfolio of seaweed systems would probably be necessary to realize the variety of benefits that these systems are capable of generating.

Posted Potential role of seaweeds in climate change mitigation on Documents
Seaweed (macroalgae) has attracted attention globally given its potential for climate change mitigation. A topical and contentious question is: Can seaweeds' contribution to climate change mitigation be enhanced at globally meaningful scales? Here, we provide an overview of the pressing research needs surrounding the potential role of seaweed in climate change mitigation and current scientific consensus via eight key research challenges. There are four categories where seaweed has been suggested to be used for climate change mitigation: 1) protecting and restoring wild seaweed forests with potential climate change mitigation co-benefits; 2) expanding sustainable nearshore seaweed aquaculture with potential climate change mitigation co-benefits; 3) offsetting industrial CO2 emissions using seaweed products for emission abatement; and 4) sinking seaweed into the deep sea to sequester CO2. Uncertainties remain about quantification of the net impact of carbon export from seaweed restoration and seaweed farming sites on atmospheric CO2. Evidence suggests that nearshore seaweed farming contributes to carbon storage in sediments below farm sites, but how scalable is this process? Products from seaweed aquaculture, such as the livestock methane-reducing seaweed Asparagopsis or low carbon food resources show promise for climate change mitigation, yet the carbon footprint and emission abatement potential remains unquantified for most seaweed products. Similarly, purposely cultivating then sinking seaweed biomass in the open ocean raises ecological concerns and the climate change mitigation potential of this concept is poorly constrained. Improving the tracing of seaweed carbon export to ocean sinks is a critical step in seaweed carbon accounting. Despite carbon accounting uncertainties, seaweed provides many other ecosystem services that justify conservation and restoration and the uptake of seaweed aquaculture will contribute to the United Nations Sustainable Development Goals. However, we caution that verified seaweed carbon accounting and associated sustainability thresholds are needed before large-scale investment into climate change mitigation from seaweed projects.
