Investment Rating - The report does not provide a specific investment rating for the livestock industry. Core Insights - Livestock farming plays a crucial role in food security and cultural significance across various regions, adapting to diverse environments and providing essential resources for human communities [11][14]. - The livestock sector significantly contributes to greenhouse gas emissions, particularly methane, which is produced during the digestion of ruminants [26][28]. - Climate change poses risks not only to the environment but also to animal health and welfare, affecting livestock productivity and the livelihoods of farmers [30][45]. Summary by Sections Livestock Farming Overview - Livestock farming has been practiced for thousands of years, providing meat, milk, and other products essential for human survival [11]. - The industry encompasses various farming systems, including extensive, intensive, and mixed systems, each with different environmental impacts [15][16]. Climate Change Impact - Climate change is characterized by long-term alterations in temperature and rainfall, leading to extreme weather events that affect livestock health and productivity [19][30]. - The average global temperature has increased by 1.1 degrees Celsius over the past century, exacerbating weather-related challenges for livestock farming [21]. Methane Emissions - Ruminants produce significant amounts of methane, with each cow or buffalo generating between 40 and 140 kg annually, contributing to nearly one-third of human-related methane emissions [28][26]. - Methane is a potent greenhouse gas, trapping heat in the atmosphere much more effectively than carbon dioxide [26]. Solutions and Strategies - Sustainable practices such as improved animal nutrition, rotational grazing, and selective breeding can help reduce methane emissions while maintaining livestock productivity [36][42]. - The FAO is actively involved in promoting sustainable livestock farming practices to mitigate climate change impacts and enhance food security [34]. Global Initiatives - The Paris Agreement emphasizes the importance of agrifood systems, including livestock, in climate action, with annual conferences to set goals for reducing greenhouse gas emissions [33]. - The FAO supports countries in managing livestock-related emissions and adapting to climate change through research and technical assistance [34].
