In 2014, all man-made sources of greenhouse gas (GHG) emissions in the U.S. were estimated to be 6,870.5 MMT CO2e (millions of metric tons carbon dioxide equivalent). Agriculture was estimated to be responsible 8.3% of those emissions (573.6 MMT CO2e per year). When looking specifically at animal agriculture, all different species together emit an estimated 243.4 MMT CO2e/year, which is 3.5% of all U.S. emissions. The pork industry is estimated to have emitted 26.6 MMT CO2e or 0.34%. (Source: US EPA Greenhouse Gas Inventory 2015)
The two areas where the swine industry produced measurable contributions to agricultural emissions include:
Enteric fermentation – the release of gases during normal digestion by animals. Pigs release approximately 2.4 MMT CO2e of the of the 164.3 MMT CO2e produced by all livestock and poultry in the U.S.
Manure management – pig farms are estimated to release 24.2 MMT CO2e of the 78.7 MMT CO2e produced by all animal manure systems in 2014.
Manure management is planned using a total system approach. Animal manure management systems involve six basic functions: production, collection, transfer, storage, treatment and utilization. The first five out of those six make up the manure management number above. Utilization (usually by land application to crop fields) is instead categorized within “Agricultural soil management”. The greenhouse gases emitted from manure systems include methane and nitrous oxide which form as manure decomposes.
When all of the GHGs emitted during a particular activity or process are added together, it is the carbon footprint. The standardized procedure to calculate carbon footprints is a life cycle analysis or LCA.

Dr. Robert Mace, Deputy Executive Director, Texas Water Development Board
Value of water to agricultural communities
In addition to the Ogallala Aquifer, there are two deeper ones including Edwards-Trinity and Dockum (Santa-Rosa). All are part of the High Plains Water District, an organization that has undergone extensive planning and outreach efforts. They have developed a tool to look at each permitted well in the district and its characteristics. The presenter also discussed the groundwater rights of land owners and the “water-neutral” business model adopted by some and the potential for this to attract new business in water-limited areas. https://youtu.be/DHtR-d_AUoA
Jason Coleman, P.E. General Manager, High Plains Water District
The shale boom—Impacts for agriculture production and producers
The nature of the oil business is often that there are “booms” in local areas when reserves are discovered or when prices make a particular resource worth developing. This presentation discusses some of the activity in the U.S. and especially Texas and how the industry has evolved technologically. The need for long-term planning to leverage these resources into long-standing infrastructure and development for community is also highlighted. https://youtu.be/HZibOjAfGb4
Dr. Thomas Tunstall, Research Director, The University of Texas at San Antonio, Institute for Economic Development
The future of renewable energy and agriculture
This presentation discusses the overall energy needs of the U.S.and creative ways that energy needs can be evened out at grid-scale decision levels that involve very local (domestic water heater or electric car) ways to “store” excess energy and use it when needed. These types of decisions could reduce the needs for new power plant construction or need to bring a plant online for short periods of time for peak demand. As agriculture on on the “edges” of the grid, it could be part of the areas where change is likely to happen first. https://youtu.be/6QrXKOLmEZ8

Most farmers and ranchers are acutely aware of weather and how it factors into their risk management planing. Climatologists have indicated that the trend toward more extreme events and greater extremes is going to continue. This has many implications for animal agriculture producers. The farmers featured in this Waste to Worth panel all provided their perspectives on adapting to extreme events through diversity, building resilience, and keeping an eye toward long-term profitability.
Diversity, Resilience and Manure Management with Cover Crops
A former ag teacher, Keith Berns understands that you need to be open to multiple ways of achieving a goal. His desire to build resilience into his farm system led to a business selling cover crop seeds that emphasize diversity. He outlines several scenarios where he uses cover crops on his farm and also several ways his seed customers utilize diverse cover crop and annual forage mixes. High stocking densities naturally incorporate manure, and residue helps conserve and hold valuable moisture during/after extreme rainfall events. [Nebraska/Kansas]
Perspectives On a Changing Climate
Dr. Sandra Matheson, DVM (retired) raises grass-fed beef cattle on her northwestern ranch. Weather extremes have created more dust, mud, and she has seen an increase in disease and health issues with cattle. She utilizes the decision-making process, holistic management, and planned grazing to create a system with the greatest amount of adaptability and resilience for her environment and its potential extremes. Her goals converge around building the soil. [Washington]
Grazing Dairy Finds Plants that Work in Low Water Environments
Michael DeSmet watched his cows when they entered a new paddock and noticed something surprising – they liked weeds. Upon further investigation, he found out that the weeds they were selecting were high-protein, palatable, and could survive on very small amounts of precipitation. Michael was no stranger to making changes; he had already converted the family dairy operation into a grazing-based system selling milk into niche markets. He continues to examine forage options for his pastures that allow the farm to utilize limited water, extend the grazing season, and improve soil quality. [New Mexico]
