Membership listserv- updating and keeping current 3. MSU Adobe Connect site retirement 4. Webinars 5. Election of officers 6. 2016 annual meeting location A. Review of 2015 annual meeting • Meeting location and available facilities were great and worked well for the planned activities. • A total of 15 participants attended. Attendance by all registered members would be desirable. • Ron Lacewell noted that the deadline for submitting the S1032 annual report was 90 days after the meeting date. The report should include: minutes of the business meeting; attendees with e-mails and location; brief annual progress report; and impact statement(s). B. Membership listserv – updating and keeping it current • Current listserv includes people who have retired and others who have not attended the annual meetings and submitted state reports in a long time. After discussions the group recommended that Jactone (secretary) and Deanne (chair) work with Dr. Lacewell to identify listed participants who have retired and those who have not submitted state report for the last 2 years. Dr. Lacewell to follow up with the identified participants about their interest and continued participation on the project. C. MSU Adobe connect • MSU will discontinue the use of Adobe connect effective June 30, 2015. Need to identify how to download and store S1032 recordings on Adobe connect. Desire to keep recordings for a year. Brent will check AgriLife for availability of space to store recordings. • MSU is moving to a new program called Zoom Pro. It provides unlimited time per session with up to 25 participants. Higher versions are available to accommodate more participants – but there may be charges for use. Can see all participants and also record and remove within 30 mintes. • Need to decide on Zoom or WebEx for coming webinars. D. Webinars • Webinars identified as a platform for continued discussions on how to encourage/engage others to participate in project. Webinars should cover topics focused on modifying/clarifying the CLD to make it relevant and realistic to participants work. Need to make it clear that the CLD is a schematic to show our collective work. Although incomplete/work in progress, we need to document what we think we know or what we know to the best extent possible. This could be done through examples including: identification of problems/individual stories should be encouraged; use to serve as guidance for technology development; have individuals identify the connection/species/scope; what research is needed to impact the system; arrangements of nodes and loops that give rise to predictable behavior; identification of change of parameter/node may or may not impact behavior since the structure is dominant in some cases. The schedule for the webinarand the topics to be covered for the coming year are listed below. All webinars will be conducted at 2 PM EST (11 am PST; 1 pm CST) - August 28, 2015. Describe social science interactions with the S1032 group. John Classen to lead and work with Jovana Vukovic and Ed Kick on developing the story line to guide webinar. Expand the population node to identify relevant variables. Map and describe the storyline from a social scientist point of view. - September 25, 2015. Focus on the manure value node (R10). Eric Cortus and Amy Schmidt to develop and lead the seminar. - October 23, 2015. Focus on data set/management based on White et al. (2013) – computers and electronics in agriculture paper.

The accomplishments (collective and state based) for this reporting period are listed by the projects three objectives below. The participating states and respective principal investigators (PIs) are listed in Table 1. Objective 1: Engage collaborators from needed broad range of disciplines, institutions, and stakeholder groups to catalyze conceptual and quantitative synthesis, collaboration, and data sharing. Planned activities to accomplish this objective include: create more learning and idea generation opportunities by increasing regular interactions among project participants using webinars and annual meeting format that allows structured analysis and discussions to achieve the goals of the group. Project participants completed the activities listed below towards this objective. • Hosted two group webinars to continue discussions to enhance our understanding of the causal loop diagram (CLD) is an attachment to the minutes and available from Lacewell (r-lacewell@tamu.edu), brainstormed topics and abstracts to collectively prepare for the Collaborative Modeling conference held at Michigan State University in June 2015, discussed USDA NIFA and other funding opportunities relevant to the group. The group led by Meyer (chair) prepared and submitted a $4,000,000 proposal to the USDA-NIFA Coordinated Agricultural Program. • Structured the 2015 annual meeting agenda to a group discussion focus. The three discussion topics included: review of March 26, 2015 webinar content that centered around B14 node/loop of the CLD and heard examples from other project participants directly working on constructing the CLD or portions of it; developing data structures and data units using information presented in White et al. (2013)[Integrated description of agricultural field experiments and production: The ICASA Version 2.0 data standards]. Computers and Electronics in Agriculture 96:1-12 as guide; and how to use webinars more effective as a group to advance our course. • Several participants attended conferences held by other professional societies (such as Ecological Society of America meetings, a Collaborative Modeling conference held at Michigan State University) to grow/seek new disciplines to contribute to our network of collaborators. This resulted in identification of potential new project participants and collaborators (including sociologists, community leaders, systems analysts, and dynamic modelers) for future grant opportunities. These disciplines would build on the skills of current membership. • Some members’ sought collaborators working on/or associated with sustainability of agricultural production, especially for animal agriculture. Various governmental agencies (USDA, EPA, and National Library, non-profits such as Field to Market and other NGO's plus commodity groups. Building networks where information and data can be shared will provide a strong baseline of materials from which inferences and concepts can be developed and implemented. • Engaged a number of outside groups and agencies including the USDA Climate Hubs concerning our efforts to build capacity for providing education programs and material on climate change and animal agriculture.

Marty Rhoades Jovana Vukovic Virginia Jactone A. Ogejo B13, B14, B15, B19 Lagoon, biodigesters The base causal loop diagram (CLD) is applied to facilitate organization, synthesis, and integration of component-based research findings and supporting data. This is the basis of S-1032. The CLD is available from Lacewell (r-lacewell@tamu.edu). It is required to interpret Table 1 information. Objective 2. Facilitate organization, synthesis, and integration of component-based research findings and supporting data. The underlying premise of this objective is that project participants collaborate or work together in teams to build a component(s) of the relational aspects of animal protein production presented in the CLD. Participants will make/share data available to support the CLD work via a publicly accessible database. Planned activities to meet this objective include: (1) identifying the types of data participants have or being generated in their current work and (2) designing and hosting a publicly accessible database for sharing project data by participants to facilitate development/integration of system components outlined in the CLD (figure 1). The accomplishments towards achieving this objective include: • Project participants identified the relevant nodes relevant to their work and also indicated sets of data they have available to share as listed in table 1. • Form groups using the self-identification and to refine and construct the CLD. Some examples of specific data available and/or current research activities by project participants to generate data for potential use in completing the CLD are listed below. Arkansas: working on node B19 of the CLD on the use of renewable energy. They will generate data to develop a cost effective advanced anaerobic digester system that uses dry poultry litter as feedstock. California: working in the areas of conversion of feed nutrients to product (salt sequestration), technology evaluation for nutrient relocation, environmental regulations, and biodigesters. Some data available to share include: Pond data—multiple locations/depths/sampling events TS, VS, Redox, EC, Temp, and pH; nutrient application to fields—wastewater application rates macro nutrient analyses (not sulfur); feed inventory analyses on commercial operations/milk exports animal exports (micro some micro analyses); solid separation (influent and effluent and particle size quantification of TS and VS), settling basins, and other separation devices; total collection data (calves, heifers, dry cows, lactating cows, goats) used for ASABE D384.2; ammonia and PM analysis in conjunction with dust control; and pharmaceuticals. Iowa State: collecting data using wet scrubber and advance oxidation technologies to mitigate particulate matter, odor, volatile organic compounds, ammonia, and hydrogen sulfide emissions from livestock operations. Their work focuses on the confluence of B14, B15, R10, B11, and B12 nodes of the CLD. Idaho: Working on mitigating gas emissions from swine facilities and manure application land. Two wood bark based down flow biofilters have been built and demonstrated at a commercial swine nursery barn for their efficiency on reducing odor and gas emissions. They have also demonstrated dairy manure land injection technique for reducing ammonia emission and retaining nitrogen fertilizer value in soils. Kansas: Data on vegetative environmental buffers and photocatalytic technology using UV/TiO2 technologies to mitigate air emissions from swine facilities. Meta-analysis data on enteric methane emissions and ammonia emissions from beef and dairy cattle operations. Michigan: (1) Project participants Powers and Safferman and Auvermann (participant from TX) teamed up in August 2014 and initiated an M.S. program for a student to develop a portion of the CLD based on swine data collected by Powers. Their goal is to advance this work to a PhD program whereby Objective 3 goals will be included. In addition, Powers has data that could be used to further develop the CLD for a beef system that considers animal performance efficiency and resulting broader impacts on environmental metrics. (2) Safferman developed decision support tools to convert animal waste into a resource. Three tools - Michigan Waste Biomass Inventory to Support Renewable Energy (Inventory) maps organic wastes in the state of Michigan and conduct preliminary energy modeling, Anaerobic Digestion Development Iterative Tool, and the Combustion Renewable Energy Development Iterative Tool to model the economic, renewable energy production, and greenhouse gas emissions reduction from using organic residuals from farms are publically available, at no charge. Minnesota: Completed a studies that measured the impact of renewable (geothermal) energy in swine grow-finish production and quantified pig production losses due to typical heat stress conditions in a grow-finish pig production system in the Midwestern U.S. North Carolina: Ammonia recovery membrane materials are being tested for characteristics that determine flux rates which will be used in design guidance documents. Characteristics of scraped manure are being determined and the energy recovery potential being measured through anaerobic digestion and gasification. North Dakota: Scientists are exploring different options to mitigate environmental impacts from livestock production facility and manure management, while maintaining sustainable growth of the livestock industry. Nanoparticles are being applied at different application rates to investigate their effectiveness to mitigate hydrogen sulfide and GHG. Nebraska: Has data on manure application impact on soil arthropod diversity; the impact of manure application setback distance relative to nutrient transport; analysis of manure application method impact on nutrient and bacterial transport following precipitation events; spatial distribution of antimicrobial resistant bacteria; and antimicrobial resistance genes in soil receiving long-term beef manure applications. South Dakota: Collaborating with North Dakota and Nebraska) to measure nitrogen and phosphorus balance, and greenhouse gas emission from land applied beef cattle manure. Collecting nitrogen and phosphorus data from deep pit and deep-bedded confinement cattle facilities in the Northern Great Plains. The data will be used to inform and validate the Integrated Farm System Model (Rotz et al, 2014-Rotz, C.A., F. Montes, S.D. Hafner, A.J. Heber, R.H. Grant. 2014. Ammonia emission model for whole farm evaluation of dairy production systems. Journal of Environmental Quality doi:10.2134/jeq2013.04.0121). Texas: (1) Project participants DeOtte and Auvermann have demonstrated ability to reduce by fifty percent water consumption in head washes in commercial abattoirs in the Texas High Plains and have been invited to inventory other water uses in harvest process and recommend changes for further conservation; developed causal loop diagram of “early harvest to reduce impact of infectious disease”; developed routes and ports for Integrated Management Zones as part of response plan for infectious livestock disease outbreaks; and developed rudimentary LabVIEW code to simulate growth curves of Bos taurus in confinement on a daily time step - a major component of the “virtual feed yard” concept. (2) Project participants DeOtte and Casey are working on saving water during beef cattle harvest process. A new proposal to evaluate the water needed for disinfection and carcass cooling postulates a potential additional twenty percent in water savings. That is substantial monetary savings for the processor and improves potential for sustaining rural economies that rely upon water from the Ogallala Aquifer. Virginia: Continues to work on recovery of value added products from agricultural and industrial residues and agricultural air quality related to nodes B13, B15, and B19. Have data on full-scale anaerobic digesters using dairy manure. ? Objective 3. Discover (reveal), substantiate, and interpret the broader impacts of component-level modifications to animal production systems. At Iowa, a major update to the Air Management Practices Assessment Tool (AMPAT) was completed using Scientific Literature Database. A total of 267 papers were reviewed to evaluate mitigation technologies performance for emissions of odor, VOCs, NH3, H2S, PM, and GHGs and inform future research needs. The tool can be accessed at: http://www.agronext.iastate.edu/ampat/database/homepage.html In Michigan, data from a swine feeding study that measured dietary impact on air emissions and nutrient excretion will be modeled to reveal the longer term impact on soil nutrient accumulation and potential water quality. This work is in the early stages but will add in the feedback loops to the portion of the CLD under development (Objective 2). At Minnesota, research results from the renewable energy use in and the effects of heat stress on pig production in the Midwest, both validate the need for a component-level approach espoused by the S1032 project. This individual results will hopefully contribute to an overall understanding of the animal production system as laid out in the systematic and been greater than the sum of its parts when combined with other research results from other S-1032 members. Also, data from 38 dairy farms that use automated calf feeders was collected eight times over approximately 18 months to a identifying vital factors impacting calf morbidity, mortality, health and welfare when dairy calf raisers use automated calf feeders and group housing. The multidisciplinary team is considering management practices and building design and their impact on calf health, behavior and performance. North Carolina is developing CLD models of potential resource recovery technologies and schemes to connect these farm level modifications to the high level CLD. Kick and Classen are working with a graduate student to create a model of food production sustainability at the global scale. World Bank data aggregated at the national level will be used to quantify the model. In Texas, workshops (sponsored by USDA APHIS VS and DHS RRAP) are being conducted to disseminate the results implementation of food security plans (Routes & Ports and Alternative Harvest Strategies). These results are not only valuable, but preemptive should the United States encounters an outbreak of foot-and-mouth disease.
