This study evaluates the potential for improving milk production while reducing enteric methane emission through low-cost strategies, including the use of urea-treated crop residues and vaccination against East Coast Fever.

Given the importance of the dairy sector to livelihoods and its potential role in poverty reduction, this study evaluates the potential for improving milk production while reducing enteric methane (CH4) emission intensity from dairy production in Tanzania. The study reveals that improved management practices and technologies can increase milk productivity while reducing methane emission intensity in both traditional and improved dairy systems. The economic analysis shows that in improved systems, all interventions assessed were cost-beneficial, however the analysis indicates that in traditional systems, both the baseline scenario and mitigation options present economic returns of less than 1. Although the economic analysis might not directly support the application of mitigation practices in traditional systems, the study does not exclude the importance of mitigation action focusing specifically on traditional systems since their existence and persistence is already threated by the effects of climatic variability and climate change. All the mitigation options analyzed in this study presented significant gains in productivity, which in practice can generate improvements in food and nutrition security, as well as boost farmers’ incomes. Moreover, some of the mitigation options can maintain and/or improve herd parameters, feed resources and water supply during and after climate shocks, supporting these systems to move from relief to resilience.

This brief has been produced by the Food and Agriculture Organization (FAO) of the United Nations, in collaboration with the Global Dairy Platform (GDP) and the Global Research Alliance on Agricultural Greenhouse Gases (GRA) and with the financial support of the New Zealand Government. The FAO was approached by GDP and GRA to develop guidance following previous research on dairy cattle in order to support policy makers and livestock sector actors in implementing a process that captures the co-benefits of cattle health initiatives in their climate commitments. It provides examples in specific countries in collaboration with the World Bank and the International Fund for Agricultural Development (IFAD). This brief provides methodological guidance on the quantification of animal health interventions and their impact on greenhouse gas (GHG) emissions, on the basis that they deliver multiple benefits to individual farmers and society which could outweigh the costs of the intervention, particularly when considering reduced GHG emissions.

Livestock food systems need to be rapidly rethought to tackle the global climate crisis. This book examines how climate concerns for the livestock sector are governed in international law and addresses the sector's inclusion (or lack thereof) across the international governance of climate change, agriculture, forests and trade. The book provides a wide-ranging analysis of legal regimes at the international level that affect emissions from cattle (and where relevant, livestock more broadly). On this basis, tensions, interactions, and common themes for livestock emissions mitigation across the international climate change, forestry, agricultural and agri-trade regime are identified. This showcases where productive synergies and damaging tensions have emerged across the cross-cutting nature of livestock governance, enabling goals of fairer and more effective emissions mitigation for the sector to be achieved. In addition to addressing issues such as food security and public health, the book highlights the problem of affluence in reducing cattle emissions from meat consumption. This key insight is significant in terms of tackling future livestock emissions trajectories, particularly in relation to securing climate justice within the agricultural sector and securing equitable and effective livestock solutions. The book is a key text for all those with an interest in the legal governance of climate change and agriculture, adding to the timely debate on the future sustainability of the global diet and the relationship between affluence and climate change.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report is a comprehensive assessment of our understanding of global warming of 1.5°C, future climate change, potential impacts and associated risks, emission pathways, and system transitions consistent with 1.5°C global warming, and strengthening the global response to climate change in the context of sustainable development and efforts to eradicate poverty. It serves policymakers, decision makers, stakeholders and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

This FAO report presents a comprehensive global assessment of greenhouse gas emissions from livestock systems, utilizing FAO’s Global Livestock Environmental Assessment Model (GLEAM) based on the most recent available data. GLEAM also considers indirect emissions from upstream activities, such as feed and other inputs, and part of the downstream processes including post-farm transport, processing and packaging of raw products. Drawing from an extensive literature review, this publication illustrates pathways towards lower emissions through a set of interventions on both the supply and the demand sides of animal production.

Life cycle assessment (LCA) is an established methodology used to quantify the environmental impacts of products, processes and services. Circular economy (CE) thinking is conceptual way of considering the impacts of consuming resources. By taking a closed loop approach, CE provides a framework for influencing behaviours and practices to minimise this impact. Development of the circular economy is a crucial component in the progression towards future sustainability. This book provides a robust systematic approach to the circular economy concept, using the established methodology of LCA. Including chapters on circular economic thinking, the use of LCA as a metric and linking LCA to the wider circular economy, this book utilises case studies to illustrate the approaches to LCA. With contributions from researchers worldwide, Life Cycle Assessment provides a practical, global guide for those who wish to use LCA as a research tool or to inform policy, process, and product improvement.

This Working Group III contribution to the IPCC Sixth Assessment Report provides a comprehensive and transparent assessment of the literature on climate change mitigation. The report assesses progress in climate change mitigation options for reducing emissions and enhancing sinks. With greenhouse gas emissions at the highest levels in human history, this report provides options to achieve net zero, as pledged by many countries. The report highlights for the first time the social and demand-side aspects of climate mitigation, and assesses the literature on human behaviour, lifestyle, and culture, and its implications for mitigation action. It brings a wide range of disciplines, notably from the social sciences, within the scope of the assessment. IPCC reports are a trusted source for decision makers, policymakers, and stakeholders at all levels (international, regional, national, local) and in all branches (government, businesses, NGOs). Available as Open Access on Cambridge Core.

These guidelines have been drawn up as part of the AgrInvest-Food Systems Project (AgrInvest-FS), a collaboration between the Food and Agriculture Organization of the United Nations (FAO) and the European Centre for Development Policy Management (ECDPM) to promote private investments in African food systems that contribute to sustainable development objectives. The purpose of these guidelines is to serve as a reference and provide practical country-customized guidance to foster sustainable investments in agrifood systems in the four African countries covered by the AgrInvest-FS project of FAO-ECDPM.

The world’s agrifood systems are on the frontlines of climate change, both as a cause and a victim. The agrifood sector is increasingly being targeted and curbing emissions is becoming a key global investment and policy theme. 'Investing in carbon neutrality: utopia or the new green wave?' presents a comprehensive assessment of the key challenges and opportunities of carbon neutrality, and scopes out the road ahead for agrifood systems. It provides strategic insights on the actions needed to move the carbon neutrality agenda forward in terms of investment opportunities and public policy priorities, with important recommendations for development partners. This publication is part of the Directions in Investment series under the FAO Investment Centre's Knowledge for Investment (K4I) programme.
