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.

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.

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.

This book was released on 2022-01-06 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review provides an overview of the status, trends, challenges and projections for aquaculture in sub-Saharan Africa (SSA) and evaluates the major trends during previous five years. While the sector still faces various internal and external challenges, the inherent natural potential of the region and rapidly increasing demand for fish has resulted in increased prioritization of aquaculture in almost all SSA countries and the African Union and subsidiary bodies have given special attention to the sector development. In order to realize its full potential, the SSA region needs to address a combination of overarching factors limiting aquaculture development so far, such as ineffective development approaches, weak governance frameworks, underdeveloped value chains and low availability as well as the high cost of key production inputs. Strengthened value chains for tilapia and catfish, promotion of new species, improved biosecurity, continued development of certification and associated harmonized best practices, improved information systems and innovations to address climate-change related impacts are some of the matters to be addressed. Financial institutions and private sector (national and international) have equally started investing, even though in the global picture such interventions may seem negligible, which makes the continent to call for more and higher levels technical and financial assistance from international partners. Upscale the status of production and productivity via healthy investments would help the sector to generate a variety of benefits including food security, livelihoods, employment, domestic and intra-regional markets, foreign currency income and other socio-economic benefits.

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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume synthesizes research from a five year program supported by the Norwegian Agency for Development to assess how coastal communities in Tanzania can adapt to climate change impacts such as sea level rise, and better assert their rights to implement decisions regarding coastal resource management in the context of global climate change. Throughout ten chapters, the book deploys a holistic approach to adopt a conceptual model of socio-ecological systems, and characterize human-nature interactions in an integrative way to understand anthropogenic pressures on ecosystems to guide conservation and management. The book will be of interest to researchers, students studying environmental management and climate change, planners, and policy makers. The book begins by describing the biophysical and socio-economic characteristics of the Tanzanian coastal environment, then discusses the impacts of climate change on coastal resource governance, community vulnerability, and livelihood security. Then, intervention strategies are offered as a means for local communities to not only adapt to climate change impacts, but also to engage in decision-making processes to assess vulnerabilities and address challenges and limitations through educated measures. The final chapters discuss the vulnerability and adaptation of coastal communities to climate change impacts to assess how livelihoods are constructed in response to impacts, and summarize the key findings to determine the best adaptation strategies to improve adaptive capacity and reduce socio-economic vulnerability.

This book was released on 2007 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the impact on smallholder farmers of technology options developed by Uganda's National Agricultural Research Organization (NARO) to improve the productivity of the East African highland banana, a major crop in Uganda and Tanzania. The contributors survey an array of options either currently practiced or under development, including improved soil fertility management practices, conventional banana improvement, and transgenic banana cultivars. Their survey produces a number of findings with important implications for banana production: a recently developed banana hybrid adopted in Tanzania reduced the vulnerability of Tanzanian households to yield losses from pests and disease; a strong network of social ties among farmers facilitates the spread of best soil fertility management practices through farmer-to-farmer exchange; and transgenic bananas currently being developed could have pro-poor impact. Drawing on simulations of the economic benefits of these and other technology options, the contributors conclude that the current strategy endorsed by NARO, of combining conventional and transgenic approaches to mitigate the biotic pressures that cause major economic losses, is essential for sustaining banana production systems. The report serves as a valuable baseline for researchers and others interested in measuring the effectiveness of crop improvement programs.
