This book was released on 2020-05-01 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In view of all production and productivity problems the seaweed aquaculture industry has been facing as well as the impact of the seaweed die-off on the Island economy with sharp decline of income and revenues for thousands of farmers and traders and, recognizing the compounded problems that about 20,000 seaweed farmers' livelihood are based on a single aquaculture system affecting mostly women and youth, the FAO-funded Technical Cooperation Programme “Support to the Aquaculture Subsector of Zanzibar” (TCP/URT/3401) recognized and recommended the Biological and Economic Research on Seaweed as a relevant pillar of the Aquaculture Development Strategy Plan. This technical report is part of the FAO-TZ project “Support to Seaweed Diseases and Die-off Understanding and Eradication in Zanzibar” TCP/URT/3601/C1, and covers an initial analysis of the die-offs due to epiphyte infestation and ice-ice disease in Zanzibar. The assessment is mainly based on site visits to the seaweed farms in Unguja and Pemba and laboratorial analysis of collected seaweed samples conducted by the authors between February and June 2017. Findings were cross-checked with a literature review on the topic and presented during stakeholders’ meetings in both Islands.

Download or read book Social and Economic Dimensions of Carrageenan Seaweed Farming written by Diego Valderrama and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carrageenan is a gelling agent extracted from red seaweeds and it has multiple applications in the food processing and other industries. Increasing demand for carrageenan has led to rapid expansion of carrageenan seaweed (primarily Kappaphycus and Eucheuma) farming in tropical areas. This expansion is expected to continue, but many issues need to be addressed to enable the sector to develop its full potential in contributing towards sustainable livelihoods, human development and social well-being. Including six country case studies and a global synthesis, this document provides a comprehensive and balanced assessment of the economic, social and governance dimensions of carrageenan seaweed farming. Information and insights provided by this document should facilitate evidence-based decision-makings in both the public and private sectors.
Download or read book Trade and Investment in East Africa written by Binyam Afewerk Demena and published by Springer Nature. This book was released on 2022-11-01 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a thorough understanding of the key policy debates on international trade and investment for development with a focus on the East African Community (EAC) to strengthen Member States’ capacity to develop policies to promote their exports’ competitiveness and diversification. Beyond Member States’, the book serves as a base for a deeper understanding of the challenges, opportunities and requirements of the intra-continental trade agreement which is now in sight with the ratification of the Tripartite (EAC-COMESA-SADC) Free Trade Area that is critical in addressing key constraints to trade in the African continent. Moreover, the lessons from this edited volume may also extend to the challenges and opportunities of the African Continental Free Trade Area. The book brings together a comprehensive overview and an evidence-based analysis that can be considered best practice in the region. The trade and investment policy analysis of constraints and opportunities aims to improve trade and competitiveness and covers macro- (economy-wide), meso- (sectoral) and micro- (firm or household) levels. This multi-level approach is crucial for understanding how current trade and investment policies limit competitiveness and diversification in order to identify more tangible policy action for overcoming such constraints. The individual contributors follow comprehensive applied empirical approaches, and each chapter generates knowledge needed to identify key challenges and opportunities focusing on research-led policy-relevant approaches that enable readers to better understand national, bilateral, and multilateral cooperation as well as policies for sustainable development in East Africa. The contributors know the EAC context very well as their engagement in policymaking goes beyond the context of the papers they are writing about. The individual chapters were developed as part of a research and capacity building programme under the aegis of ACP and EU that we implemented in 2020-2022. The research project well fits into the Frontiers in African Business Research series as we have many African contributors. The contributions matter to policymakers and academic circles. For students, the book serves as an excellent guide for understanding international trade and investment theories and gaining up-to-date knowledge on developments in the world economy and their effects on developing countries and SDGs. Trade policy researchers and students will be able to extend theories and empirical data to address new and emerging topics beyond the settings already covered in the book.
Download or read book Seaweeds and their Role in Globally Changing Environments written by Alvaro Israel and published by Springer Science & Business Media. This book was released on 2010-06-18 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global warming is accelerating faster than the ability for natural repair, and environmental stresses are damaging ecosystems, all affecting physical and biological systems on Earth. A new Nasa-led study shows that human activity has caused climate changes resulting in permafrost thawing, acid rain, and lower productivity in lakes as well as increased emissions of greenhouse gases, including CO2, N20, CH4, CF3, and CFC. Marine plants play a vital role in maintaining the balance of marine environments, while serving as a source of food for humankind and important chemical compounds. Microalgae and seaweed have enormous potential for reducing global warming and climate change. During photosynthesis algae grow, draw CO2 from the atmosphere, release oxygen, and produce solar biofuel. Experts in the life of marine plant ecosystems in globally changing environments contributed chapters to this book. The target readers are phycologists, ecologists, atmospheric scholars, conservationists, environmentalists, and ecologically aware laymen.
Download or read book Seaweeds and microalgae written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-07-16 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae, including seaweeds and microalgae, contribute nearly 30 percent of world aquaculture production (measured in wet weight), primarily from seaweeds. Seaweeds and cmicroalgae generate socio-economic benefits to tens of thousands of households, primarily in coastal communities, including numerous women empowered by seaweed cultivation. Various human health contributions, environmental benefits and ecosystem services of seaweeds and microalgae have drawn increasing attention to untapped potential of seaweed and microalgae cultivation. Highly imbalanced production and consumption across geographic regions implies a great potential in the development of seaweed and microalgae cultivation. Yet joint efforts of governments, the industry, the scientific community, international organizations, civil societies, and other stakeholders or experts are needed to realize the potential. This document examines the status and trends of global algae production with a focus on algae cultivation, recognizes the algae sector’s existing and potential contributions and benefits, highlights a variety of constraints and challenges over the sector’s sustainable development, and discusses lessons learned and way forward to unlock full potential in algae cultivation and FAO’s roles in the process. From a balanced perspective that recognizes not only the potential of algae but also constraints and challenges upon the realization of the potential, information and knowledge provided by this document can facilitate evidence-based policymaking and sector management in algae development at the global, regional and national levels.
Download or read book African Handbook of Climate Change Adaptation written by Walter Leal Filho and published by Springer. This book was released on 2021-05-21 with total page 2838 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book discusses current thinking and presents the main issues and challenges associated with climate change in Africa. It introduces evidences from studies and projects which show how climate change adaptation is being - and may continue to be successfully implemented in African countries. Thanks to its scope and wide range of themes surrounding climate change, the ambition is that this book will be a lead publication on the topic, which may be regularly updated and hence capture further works. Climate change is a major global challenge. However, some geographical regions are more severly affected than others. One of these regions is the African continent. Due to a combination of unfavourable socio-economic and meteorological conditions, African countries are particularly vulnerable to climate change and its impacts. The recently released IPCC special report "Global Warming of 1.5o C" outlines the fact that keeping global warming by the level of 1.5o C is possible, but also suggested that an increase by 2o C could lead to crises with crops (agriculture fed by rain could drop by 50% in some African countries by 2020) and livestock production, could damage water supplies and pose an additonal threat to coastal areas. The 5th Assessment Report produced by IPCC predicts that wheat may disappear from Africa by 2080, and that maize— a staple—will fall significantly in southern Africa. Also, arid and semi-arid lands are likely to increase by up to 8%, with severe ramifications for livelihoods, poverty eradication and meeting the SDGs. Pursuing appropriate adaptation strategies is thus vital, in order to address the current and future challenges posed by a changing climate. It is against this background that the "African Handbook of Climate Change Adaptation" is being published. It contains papers prepared by scholars, representatives from social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects in Africa, and working with communities across the African continent. Encompassing over 100 contribtions from across Africa, it is the most comprehensive publication on climate change adaptation in Africa ever produced.

Download or read book Thematic Background Study Genetic resources for farmed seaweeds written by Hurtado, A.Q. and published by Food & Agriculture Org.. This book was released on 2022-01-21 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing global population needs to source food from the ocean, which is a much greater area than the land. The ocean is rich with diversified flora and fauna, and both are sources of proteins, vitamins, minerals, phytohormones, and bioactive compounds. Thousands of species of macroalgae (seaweed) dominate the vegetation of the seafloor from the intertidal to the subtidal zone. The domestication of several economically important seaweed such as Saccharina, Undaria and Pyropia in China, Japan and the Republic of Korea, and Kappaphycus and Eucheuma in Indonesia, Malaysia, the Philippines and the United Republic of Tanzania led to the intensive commercial cultivation of these seaweeds. Except for the United Republic of Tanzania, the commercial farming of seaweed, both temperate and tropical species, is centred in Asia. Despite the presence of several economically important seaweeds outside Asia, commercial farming is practised only in a few of non-Asian countries. These include Chile for Gracilaria and Macrocystis (Buschmann et al., 2001); France for Palmaria palmata, Porphyra umbilicalis and Undaria pinnatifida (Netalgae); and Canada for Saccharina latissima in integrated multi-trophic aquaculture (IMTA) (Chopin et al., 2013) and Chondrus crispus. Trial cultivation of Saccharina spp. and P. palmata is now taking place in Western Europe. Seaweeds are farmed mainly for food such as sea vegetables and food ingredients (Bixler and Porse, 2011), as well as feed (Wilke et al., 2015; Norambuena et al., 2015). However, there is increasing interest in their use for biorefinery products that require a vast amount of biomass which must be farmed.
Download or read book Sustainable Global Resources Of Seaweeds Volume 1 written by Ambati Ranga Rao and published by Springer Nature. This book was released on 2022-03-28 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine plant life is an abundant source of nutrients that enhance the daily diet. In recent years, consuming diets rich in seaweeds or their extracts have been shown to provide health benefits due to being rich in macronutrients, micronutrients and nutraceuticals. The commercial value of seaweeds for human consumption is increasing annually, and some countries harvest several million tons annually. The seaweeds industry is valued at around $12 billion in 2017, and supports millions of families worldwide. Seaweeds production grew globally by 30 million tons in 2016. Seaweeds have seen increasing usage in the food industry due to their abundance of beneficial nutrients, vitamins and ω–3 fatty acids. To date there have been no books that comprehensively cover up-to-date information on seaweeds cultivation, processing, extraction and nutritional properties. This text lays out the properties and effects of seaweeds from their use as bioresources to their use in the feed industry to their applications in wastewater management and biofuels. Sustainable Global Resources Of Seaweeds Volume 1: Industrial Perspectives offers a complete overview of seaweeds from their cultivation and processing steps to their bioactive compounds and Industrial applications, while also providing the foundational information needed to understand these plants holistically. Chapters in this volume focus on seaweeds bioresources, ecology and biology, composition and cultivation, plus usage of seaweeds extracts for the feed industry. An entire section is dedicated to waste water treatment, bioremediation, biofuel and biofertilizer application of seaweeds. For any researcher in need of a comprehensive and up-to-date single source on seaweeds cultivation, this volume provides all the information necessary to gain a thorough understanding of this ever-important product.
Download or read book Climate change Unpacking the burden on food safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-03-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.
