Book Description
Livestock production systems are generally considered to have various negative environmental impacts, including nutrient leaching, and a significant contribution to global warming. In this respect, the reduction of gas or ammonia emissions can be achieved through improved efficiency in the choice of feedstuffs. The use of alternative feeds or additives can contribute to a more energy-efficient ration with lower emissions. Such strategies can contribute to improved animal production and health status. Studies have reported that feed additives such as nitrogen-containing compounds, probiotics, prebiotics, and plant extracts significantly reduce ruminant methane. Moreover, research suggested that fruit pomaces could be a low-cost fibre source in poultry nutrition, and that the inclusion of orange pulp in pigs’ diets can reduce the potential ammonia and methane emissions. To properly evaluate the most adequate reuse strategy it is necessary a specific life cycle assessment for each co-product.

Book Description
Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Book Description
JAMES BEARD AWARD WINNER IACP Cookbook Award finalist In the face of apocalyptic climate change, a former fisherman shares a bold and hopeful new vision for saving the planet: farming the ocean. Here Bren Smith—pioneer of regenerative ocean agriculture—introduces the world to a groundbreaking solution to the global climate crisis. A genre-defining “climate memoir,” Eat Like a Fish interweaves Smith’s own life—from sailing the high seas aboard commercial fishing trawlers to developing new forms of ocean farming to surfing the frontiers of the food movement—with actionable food policy and practical advice on ocean farming. Written with the humor and swagger of a fisherman telling a late-night tale, it is a powerful story of environmental renewal, and a must-read guide to saving our oceans, feeding the world, and—by creating new jobs up and down the coasts—putting working class Americans back to work.

Book Description
This study is a first attempt to estimate the impact of a red seaweed (Asparagopsis taxiformis) feed additive on total emissions from cattle and the feasibility of scaling up farmed seaweed production to meet projected demand from the livestock sector. The approach used for the analysis combines projections of supply and demand of beef and milk production to 2050 with a cattle herd model that allows calculation of animal categories by age and sex, animal weight and production, and feed intake and methane emissions from cattle. At the time of this study, the seaweed additive showed limited applicability in grazing systems as it has been used experimentally, mostly incorporated in mix rations for each treatment animal, with not enough evidence available at present to determine the time of decay of the active component in seaweed after consumption by animals with limited access to the additive. Given these limitations, this study assumes that the applicability of the seaweed additive could be extended in the future to most dairy systems via slow-release formulations that have already been developed for other CH4 inhibitors and that can be fed daily during milking time. Based on this assumption, the maximum potential reduction of enteric methane emissions of the new technology is analyzed by projecting a scenario where the seaweed additive is supplied globally to dairy cows. Results show that the seaweed additive could result in a reduction of up to 10 percent in total methane emissions from cattle compared to a No-Seaweed scenario. Most of this reduction was driven by decreased emissions in Latin America, South Asia, and sub-Saharan Africa. The estimated reduction in feed intake associated with the seaweed additive was equivalent to an annual reduction in grain consumption of approximately 50 kgs per cow, or US$5 billion in global cost savings per year. The total amount of dry seaweed needed to supply dairy cows in 2050 was estimated at 5 million metric tons per year, representing 18 percent of the world’s seaweed-farmed area. Simply assuming the sector’s long-term historical average growth rates, this production level might be reached in approximately 20 years, although there are still several open questions about production and technologies and high variability in production costs and producer prices, as A. taxiformis is not extensively produced at present. Available knowledge on seaweed production seems to suggest that, at least at the start, production of A. taxiformis will be by nearshore culture. Expansion of nearshore culture could result in site competition with established seaweed production, access to operational license and government approvals in several countries, licenses to use livestock feeds incorporating seaweed as a feed additive, and more research to demonstrate the safety and efficacy of the additive in accordance with country’s regulations. The best possibilities for the development of production A. taxiformis seem to be in South Asia, for its growing demand and production of dairy products, its importance in terms of global emissions, and its location near the best- and well-established seaweed production areas in Southeast Asia.

Book Description
Monitoring oceans and coastal areas has a fundamental social impact, and this scenario is made still more challenging with the present and future issues related to climate change. In this context, radar systems have gained increasing interest, since they are remote sensing devices capable of providing information about sea waves, currents, tides, bathymetry, and wind. Moreover, radar systems can be designed to perform both large-scale and small-scale monitoring, with different spatial and temporal resolutions, and can be installed on different observation platforms (ship-based, ground-based, airborne, satellite or drones). In this regard, this book aims at engendering a virtual forum for ocean radar researchers, where state-of-the-art methodologies and applications concerning ocean monitoring by means of radar technologies are reviewed and discussed.

Book Description
The main effects of Seaweed extracts (Ascophyllum, Fucus, Sargassum, Saccorhiza, Laminaria, Gelidium and others), when used as agricultural fertilizers, are better seed germination and higher quality fruit production, with longer shelf life; better use of soil nutrients; more productive crops and plants with greater resistance to unfavorable environmental conditions. Algae also have a long history of use as animal feed. They have a highly variable composition depending on the species, collection season and habitat, and on external conditions such as water temperature, light intensity and nutrient concentration in water. In relation to ruminal fermentation, a high variability of the digestibility values was found among seaweed species and cannot be attributed only to the composition of different nutrients of the algae. The role of marine algae for reduction of methane production is discussed with particular emphasis on novel algae-based feed strategies that target minimal methane emissions without affecting the functionality of the microbiota and overall animal productivity.

Book Description
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.
