Book excerpt: Global aquaculture makes an important contribution to food security directly (by increasing food availability and accessibility) and indirectly (as a driver of economic development). In order to enable sustainable expansion of aquaculture, we need to understand aquaculture’s contribution to global greenhouse gas (GHG) emissions and how it can be mitigated. This study quantifies the global GHG emissions from aquaculture (excluding farming of aquatic plants) and explains how cost-effectiveness analysis (CEA) could be used to appraise GHG mitigation measures. Cost-effective mitigation of GHG from aquaculture can make a direct contribution to United Nations Sustainable Development Goals 13 (Climate Action), while supporting food security (Goal 2: Zero Hunger), and economic development (Goal 8: Decent Work and Economic Growth).

This book was released on 2020 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruminants contribute significantly to human food security. However, the production of ruminants contributes to greenhouse gas (GHG) emissions that are responsible for climate change. GHGs such as methane, carbon dioxide, and nitrous oxide are produced from different processes of ruminant production. Ruminant enteric methane is a substantial component of methane produced by agriculture. This book presents novel and established methods in quantifying and reducing enteric methane emission from ruminants in different production systems. The book covers different types of ruminants including cattle, sheep, and goats. The chapters are contributed by scientists and authors from different parts of the world, demonstrating the importance of this problem and the universal drive for immediate and sustainable solutions. Although, biologically speaking, the production of enteric methane cannot be reduced to zero, high emissions are an indicator of inefficient digestion of feed in the rumen and low utilisation of feed energy. By presenting research that could lead to robust and yet practical quantification methods and mitigation strategies, this book not only contributes to the discourse and new knowledge on the magnitude of the problem but also brings forward potential solutions in different livestock production systems.

Book excerpt: The Food and Agriculture Organization of the United Nations (FAO) works towards ending hunger and poverty while using precious natural resources sustainably. The fisheries and aquaculture sector makes substantial contributions to food security, livelihoods and global trade. Global production of fish and other aquatic animals continued to grow and reached 179 million tonnes in 2018, and about 59.5 million people were engaged in the primary sector of capture fisheries and aquaculture. Fishery net exports generate significantly more revenue for developing countries than other agricultural commodities such as rice, coffee and tea. Millions of people are struggling to maintain reasonable livelihoods through the fisheries and aquaculture sector. These are the people who are the most vulnerable to the impacts of climate change. Climate change adds to the many threats and obstacles that already confront them in their day-to-day lives. Particular attention must be given to the most vulnerable if the sector is to continue to contribute to meeting global goals of poverty reduction and food security. This publication presents FAO’s work on climate change and fisheries and aquaculture. It includes examples of FAO’s support to countries so that they are better able to adapt to the impact of climate change in the fisheries and aquaculture sector. It also brings together FAO’s most up-to-date knowledge on climate change, including a portfolio of adaptation tools and measures used to support countries’ climate commitments and action plans.

Book excerpt: The publication "Guidance on core indicators for agrifood systems – Measuring the private sector’s contribution to the Sustainable Development Goals" aims to provide practical information on how food and agriculture companies’ contribution to the SDGs can be measured in a consistent manner and in alignment with countries’ needs relating to monitoring the attainment of Agenda 2030. The indicators are further intended to serve as a tool to assist governments in: improving private sector’s accountability mechanisms and assessing their contribution to SDG implementation, in particular on key transformative actions needed to achieve the SDGs; setting standards and policies for corporate sustainability reporting, establishing national private sector reporting mechanisms, and enabling the reporting on SDG Indicator 12.6.1 (Number of companies publishing sustainability reports); and potentially reusing the data reported by private entities to improve SDG monitoring at the national level. Available in a user-friendly format, the guidance begins with a quick guide that provides a brief overview of the indicators, the audience, scope, and data collection. It is followed by methodological guidance, which provides in-depth detail on the methodology behind each indicator and useful resources for capturing, measuring, and reporting on data for each indicator. Finally, in the annexes, there is a mapping of how the indicators align with various standards and guidance.

Book excerpt: 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.

This book was released on 2018-11-19 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study (workshop presentations, proceedings, GHG tool and recommendations) was carried out to improve FCR and asses its impact on reducing GHG emissions in Aquaculture. Three major objectives of this study was to assess the current GHG contributions of aquaculture and ways to measure it, ii) explore the potential to continue reducing FCR in salmon farming and other species, and therefore improving their environmental performance including GHG and iii) explore potential transfer of feed and fe eding technologies and lessons learn from salmon farming to other freshwater species such as tilapia, carps and catfishes and marine shrimp. The findings of this study identified several factors that affect FCRs, particularly in species farmed in developing countries, which could be targeted with programs that ultimately would reduce GHG and other emissions. The study concluded that managing environmental aspects, simplifying farm management, and improving feed management, would improve FCRs and reduce GHG emissions.

Book excerpt: ÿFish?including finfish and shellfish?are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world?s fish consumption occurs. In addition to protein, fish contain micronutrients and longchain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor. However, the global supply of wild-caught fish has long peaked and is unlikely to rise again unless overexploited stocks are rehabilitated. As world fish consumption continues to grow, aquaculture (fish farming) has emerged to meet demand. Already, just under half of all fish that people consume come from aquaculture, which is one of the world?s fastest-growing animal food producing sectors. With the supply of wild-caught fish stagnant, any future increase in world fish consumption will need to be supplied by aquaculture. This working paper explores the potential role of aquaculture in meeting global fish demand in 2050, finding that aquaculture production will need to more than double by midcentury. The authors examine scenarios of aquaculture?s growth and environmental impacts in 2050 and close with a series of recommendations for how to sustainably grow aquaculture production.
