This book collates the latest information on Kappaphycus and Eucheuma seaweeds. The edited volume provides an important companion to anyone studying or working with what is the world's largest cultivated marine plant biomass. The contributing authors have excelled in providing information on production and present and future uses of these carrageenan-bearing seaweeds. Important elements of taxonomy, distribution and methods of cultivation and processing are presented to the reader in an accessible and easily understood format. The book provides a number of valuable opinions on value addition and MUZE technologies which highlight value-chains associated with these important red algae

The Philippine seaweed industry is affected by multiple but interrelated risks. Farmers mainly encountered environment-related risks (e.g. disease, pest infestations) which, if unmanaged, could result to production failure. Traders and processors considered volatility of seaweed supply and poor quality of raw materials as precursors of other risks such as increased competition among local traders and processing companies. Gender differences in awareness and knowledge of risks were more prominent among seaweed farmers but not among traders and processors as roles become more homogenous up the value chain. Poor governance resulted in the adoption of informal and market-driven strategies to prevent or minimise losses. However, this restricted farmers to participating in higher-income trading and processing activities and contributed to increased market inefficiency. The lack of government support has also curtailed the capacity of traders and processors to engage in product development and diversification. Gender and community experiences influence and shape people's understanding of their situations and environment including their coping and adaptive strategies in sustaining livelihoods amidst recurring risk events. Embedding informal structures and the differential needs of the stakeholders in the national institutional framework is therefore essential for the promotion of resilient and sustainable seaweed industry. ; This study forms part of a larger study under the GlobalSeaweedSTAR – Safeguarding the future of seaweed aquaculture in developing countries programme which is being funded by the UK Research and Innovation – Global Challenges Research Fund, United Kingdom (Grant Ref: BB/P027806/1).

Each year a significant proportion of global food production is lost to pests and diseases, with concerted efforts by government and industry focussed on application of effective biosecurity policies which attempt to minimise their emergence and spread. In aquaculture the volume of seaweeds produced is second only to farmed fish and red algal carrageenophytes currently represent approximately 42% of global production of all seaweeds. Despite this importance, expansion of the seaweed sector is increasingly limited by the high prevalence of recalcitrant diseases and epiphytic pests with potential to emerge and with the demonstrated propensity to spread, particularly in the absence of effective national and international biosecurity policies. Developing biosecurity policy and legislation to manage biosecurity risk in seaweed aquaculture is urgently required to limit these impacts. To understand current international biosecurity frameworks and their efficacy, existing legislative frameworks were analysed quantitatively for the content of biosecurity measures, applicability to the seaweed industry, and inclusion of risks posed by diseases, pests and non-native species. Deficiencies in existing frameworks included the following: inconsistent terminology for inclusion of cultivated seaweeds, unclear designation of implementation responsibility, insufficient evidence-based information and limited alignment of biosecurity hazards and risks. Given the global importance of the cultivation of various seaweeds in alleviating poverty in low and middle income countries, it is crucial that the relatively low-unit value of the industry (i.e. as compared with other aquatic animal sectors) should not conflate with a perceived low risk of disease or pest transfer, nor the subsequent economic and environmental impact that disease transfer may impact on receiving nations (well beyond their seaweed operations). Developing a clear basis for development of robust international biosecurity policies related to the trade in seaweeds arising from the global aquaculture industry, by first addressing the gaps highlighted in this study, will be crucial in limiting impacts of pests and diseases on this valuable industry and on natural capital in locations where seaweeds are farmed.
