Non Technical Summary
For decades, the dominant paradigm in Midwestern agriculture has been the necessity of the corn-soybean rotation; as illustrated by decreased farmer economic optimism, declining rural communities, and degraded environments, this paradigm is no longer working.Our interdisciplinary and cross-organizational team will engage stakeholders across the value chain to generate evidence-based visions and frameworks to diversify the dominant corn-soybean system. The transformed system will be capable of overcoming persistent market and policy barriers to support a transition to resilient intensification and a more economically, environmentally, and socially sustainable system.These changes will be enabled byadvancing several dimensions of diversity- at the farm, landscape, and market level while ensuring the needs of diverse people along the value chain are met.Informed by stakeholders through coproduction sessions, visioning, surveys and interviews, the team will advance understanding of environmental costs and benefits of diversified systems through on-farm research and will research economic and social barriers to change along the agricultural value chain (Objective 1). The team will model air, water, and economic outcomes of baseline and diversified systems (Objective 2). Modeling results and scenario development will guide place-based visioning sessions (Objective 3). The team will identify institutional barriers (Objectives 1-3) and generate policy guidance (Objective 4). #DiverseCornBelt's Extension program will support farm-level actors and markets in transitioning (Objective 5) and will engage the future workforce through educational modules and immersive learning experiences (Objective 6).

Goals / Objectives
The core goal of this Purdue University-led SAS project, #DiverseCornBelt: Resilient Intensification through Diversity in Midwestern Agriculture, is to diversify the farms, landscapes, and markets of the Corn Belt. Our hypothesis is that diversifying crop production and markets will generate a suite of economic, social, and ecosystem services that benefit more people than provided by the current system of predominantly corn-soybean rotations and confined livestock. Diversifying both farming and farmers in the U.S.requires systematic analysis and assessment of pathways towards resilient intensification at farm, landscape, and market levels.Our team will implement a transdisciplinary integrated approach to coproduce new scientifically and ethically sound visions through objectives that cuts across research, Extension, and education.Objective 1: Coproduce research and advance market development along the agricultural value chain to identify and address social, economic, agronomic, and environmental barriers to the adoption of diverse sustainable agricultural systems.Objective 2: Model economic and ecosystem (air, water) impacts of diverse landscape scenarios across the agricultural value chain to develop evidence-based policy recommendations, quantify sustainability metrics and establish conditions required for economic vitality.Objective 3: Design stakeholder-informed alternative production systems by conducting visioning sessions at the local, state, and national levels that allow participants to consider ethical choices and sustainability outcomes.Objective 4: Develop and disseminate policy guidance to achieve resilient intensification through diversified farms, landscapes, and markets.Objective 5: Engage with diverse stakeholders through Extension to support farm diversification and market development.Objective 6: Create, pilot, and publish educational materials to foster a workforce prepared to respond to emerging challenges and support a diversified landscape.
Project Methods
Task 1A: Engage with stakeholders We will convene multiple groups of stakeholders from across the agricultural value chain, with a minimum of two groups in each of IN, IL, and IA (I-states). These groups, Reimagining Agricultural Diversity Teams (RAD Teams), will use emerging techniques like horizon scanning and futures wheels to prioritize the sustainability metrics of importance to stakeholders.Task 1B: On-Farm Research Our on-farm research will collect data to compare conventional and diversified cropping systems in replicate watersheds throughout the I-states. Farmers, and thus sites, will be recruited in Y1 through a combined effort by the Extension and research teams that will integrate existing relationships with biophysical data (e.g., SSURGO soil maps). We will identify pairs of 'diversified' and 'conventional' farms in each watershed. To separate the two, a diversification index will be used to characterize farms with a scoring matrix based on a range of factors such as rotations, crop diversity, non-crop vegetation, and livestock integration. We will select farms that still cultivate corn and/or soybeans to generate a standardized baseline to compare with conventional systems. Each farm will be sampled up to 10 times annually in Y2-4. In addition to standard agronomic soil fertility measurements, we will measure the following soil health indicators: penetration resistance, bulk density, nitrogen mineralization rate, carbon mineralization rate, and aggregate stability. Insect community indicators measured will include: predator diversity and abundance, pest suppression, and pollinator diversity/abundance. Water quality measures taken will include: groundwater recharge, and water quality (N and P in groundwater). Last, we will collect crop growth data by: (1) quantifying canopy and residue cover using the Normalized Difference Vegetation Index (NDVI), and (2) using yield data reported from farmer participants..Task 1C: Identifying challenges and assessing readiness of the value chain We will use surveys, case studies, focus groups, and interviews to increase understanding of the barriers and motivations for (i) farmers to diversify and (ii) advisers to recommend diversification as a viable strategy.Task 2A: Farm-level economic modeling of diversification We will develop a flexible farm-level economic decision model to determine the conditions under which more diverse farms can be economically viable and what tradeoffs are necessary for farm operators to diversify their operations using extended rotations, grazed livestock, perennials, or new food crops. from alternative rotations and crops/land-uses, and explicit consideration of the cost- and risk-reducing role of federal policies in perpetuating the current paradigm. We will conduct this modeling in a stochastic setting to account for climate/weather variability and other infrequent environmental stresses that may have dramatic economic consequences.Task 2B: Diversification land use change (LUC) modeling The potential LUCs in our project could go beyond the production of food for local communities and include shifts from annual crop production to longer rotations and/or managed grazing, such as corn-soybean-oat/alfalfa-alfalfa rotations with and without cattle.Task 2C: Foodshed optimization. We will evaluate foodsheds in terms of the extent to which they address issues such as food security and sustainability, as well as social and environmental impacts of food systems.Task 2D: Hydrological modeling using SWAT.Task 2E: Air quality impacts We will conduct air quality modeling using reduced-complexity models.Task 3A: Develop preliminary landscape scenarios We will visualize landscape scenarios likely to be of interest to stakeholders. We anticipate scenarios will include: (1) a baseline corn-soybean rotation; (2) incremental diversification practices such as use and frequency of cover crops; (3) targeted perennialization, such as energy "crops", kernza, and forages with pastured livestock; (4) horticultural food crops and local foodsheds; and (5) policy-driven scenarios.Task 3B: Visioning sessions These meetings will occur with RAD Teams in each state and with decision makers at state and national levels and will generate visions for viable scenarios (or plausible futures) that maximize the sustainability outputs earlier prioritized by participants in each RAD Team.Task 4A: Outreach to Federal Decision-Makers We will generate a series of policy alternatives to be shared in-person with legislative and agency staff in two concurrent events in Washington, D.C.Task 4B: Outreach to State and Local Decision-Makers We will prepare state-specific topic briefs and policy papers adapted from the federal documents. Team members in each state will disseminate these through in-person meetings with key legislators and agencies, and at conferences and other appropriate venues.Task 5A: Engage with farmers and other farm-level decision-makers We will share research findings about: consumer demand that could be met through diversification; relationships between diversification, soil health, and sustainability; developing markets that support diversification; and what approaches to diversification are likely to be most profitable.Task 5B: Pilot markets and agricultural value chain dialogues Wwe will engage at least one food or beverage company to implement a pilot market to source sustainably produced crops from farms in the region. In addition, we will engage at least one of our existing food and beverage company partners to help expand their current pilot to build lasting market infrastructure and test consumer-facingTask 6A: Employ formal educational evaluation strategies to test and assess student learning outcomes In year one, UMN will host a mini-retreat to define student learning outcomes (SLOs) and design educational modules to meet them.Task 6B: Develop collections of learning modules to enhance agricultural sustainability education in secondary and undergraduate classrooms We will design modules for existing courses that are transferable and accessible to larger learning communities. These modules will be informed by the project's research objectives and latest findings and will consist of material for lectures as well as hands-on and active learning classrooms. Modules will be shared across the grant institutions where their efficacy and alignment with stated educational goals will be tested.Task 6C: Create an experiential multi-institutional field course to be taught over the summer session We will design a multi-institutional, 10-day summer travel course, the "Midwestern Sustainable Ag Tour."Year One Evaluation: The first year of evaluation will be designed to: assist the research team in clarifying research strategies; finalizing milestones; identifying communication processes; developing a framework for stakeholder engagement; and establishing research-team operations and responsibilities. Years Two, Three, and Four Evaluation: formative evaluation will be conducted through interviews (in person or virtually), surveys, and document analysis to compare projected milestones with results. Year Five Evaluation: A summative evaluation of the project will be conducted with an emphasis on research objectives, communication processes, stakeholder engagement, and research-team operations.Evaluation of Extension efforts: We will conduct pre- and post-surveys of collaborating farmers to assess knowledge gained, and views on benefits of and barriers to diversification.Evaluation of education efforts:" Evaluation efforts will focus on implementation, efficacy, and impact of the modules on SLOs.

Outputs
Target Audience:DCB target audiences include: Farmers; agricultural advisors; landowners; food, fiber, biomass retailers; Land Grant University Extension; policy makers/funders; students; educators; researchers. Changes/Problems:The following changes have occurred: This grant funds a software fee for PFI to host an oat selector tool. However we made the decision to take down this tool, since it was not being updated, in February of 2024. This winter we will brainstorm how to spend down those funds and if there is a different software use that could have similar goals. Instead of holding on-farm field days in each state the third year of the project, DCB decided to sponsor or support field days that provide stakeholders with information about diversified systems that are organized by groups with expertise in those systems. Added Cate Loomis and Anya Knecht in spring 2024 to help with coordination and extension/outreach efforts in Illinois. Added Dr. Moriah Bilenky, Purdue to Educationteam What opportunities for training and professional development has the project provided?DCB is providing training and professional development to 7 graduate students and 5 post-docs. DCB has also supported conference and seminar attendance for PIs, students, post-docs, and staff. How have the results been disseminated to communities of interest?The DCB team has disseminated information and results to our target audience through various channels. DCB has supported publication of 12 newsletters and blog posts on diversified agriculture, expanded the DCB website to include additional resources and event information, and maintained an active presence on X, Facebook, and LinkedIn, all key communication platforms for reaching a broad range of stakeholders. DCB shared findings through 37 conference presentations, attended seven field days, and facilitated peer-to-peer learning with seven extended rotation network calls. Additionally, DCB engaged with key communities in the study region to recruit participants and gather feedback in RAD meetings. The team also published a public-facing Year 2 report summarizing project results, 18 peer-reviewed publications and 9 reports. DCB has also sponsored and had a presence at key gatherings inducing the Sustainable Ag Summit and the Illinois Organic Grains Conference. The DCB website continues to expand resources and the DCB newsletter has a growing list of 600+ recipients. These efforts have enabled broad engagement with the diverse stakeholders involved in the DCB project. What do you plan to do during the next reporting period to accomplish the goals?OBJ1: DCB will continue conducting RAD team meetings across the study region to explore social and economic barriers and opportunities for diversification. The team will analyze, synthesize, and share findings with participants, co-creating shared visions for the future of Midwestern agriculture. Addressing agronomic and environmental elements, DCB will continue data collection, analysis, and synthesis. Related to market development, DCB will continue analysis and synthesis of qualitative and quantitative data related to markets and consumer preference. DCB team will continue working to support development of rye markets with Smithfield Foods. All results from OBJ1 (social, economic, agronomic, environmental) will be incorporated into subsequent tasks and activity. OBJ2: DCB will continue efforts related to farm-level economics, land-use change, air quality, food shed, water quality and agent-based modeling. Models are informed by Obj 1 results and will be the starting point for stakeholder-informed visioning sessions focused on the future of agriculture in the Midwest. OBJ3: Closely related to OBJ1, the DCB team will continue gathering data and recruiting participants who will contribute to the stakeholder-informed visioning sessions. OBJ4: DCB will continue exploring policy opportunities and alternatives through the ongoing results of stakeholder engagement and findings from OBJ1. DCB will continue networking with policy advocates and planning strategies for developing stakeholder-informed policies that support a more resilient agriculture future in the Corn Belt. OBJ5: DCB will continue developing relationships with key organizations and stakeholders across the ag value chain to support farm diversification and market development. We will use these relationships to leverage the efforts of our team and support development of organizations who can extend the reach of DCB findings. DCB will also develop extension documents outlining key research findings. OBJ6: DCB will continue module development and recruiting content experts to develop specific modules. Modules will be designed at the college level and will be tailored to fit the needs of a high school classroom. We will also hold a multi-state "Midwestern Sustainable Agriculture Tour" highlighting diversified agriculture and relevant socio-cultural sites across the Corn Belt. This program will also be made available to secondary agricultural education teachers as a form of professional development, providing the additional benefit of helping them implement learning modules.

Impacts
What was accomplished under these goals? OBJ 1: DCB has made great progress exploring opportunities and challenges for diversification related to social, economic, and biophysical elements. Informed by DCB focus groups, a manuscript was published in Agriculture and Human Values in June 2024, highlighting the value of diverse perspectives in shaping sustainable agricultural practices. The project's Reimagining Agricultural Diversity (RAD) Teams hosted six meetings across Illinois, Indiana, and Iowa, engaging 154 participants, including farmers, advisors, landowners, and local decision-makers. RAD Teams function as long-term stakeholder groups that provide critical feedback, discuss project findings, and inform future visions and state-specific pathways to increase agricultural diversification. Using interactive facilitation methods, the first RAD meetings focused on establishing participant priorities and collecting insights on the current state and future potential of agricultural diversity. The second round of meetings built on this foundation by incorporating participant feedback and engaging them in discussions about envisioning future landscape-scale changes in the Corn Belt. Data collected from these sessions is currently being analyzed to guide upcoming meetings. Results from a farmer survey conducted in January 2023 have been drafted into a manuscript, currently undergoing revision after first round of peer reviewby Renewable Agriculture and Food Systems. Horizon scanning techniques have also been employed to gain insights into future opportunities and challenges related to agricultural diversification in the Corn Belt. By monitoring popular press sources over a six-week period, the team identified emerging trends, potential threats, and opportunities in agriculture. Final analysis is underway with plans for publication. Horizon scans are important to inform strategic responses to evolving agricultural landscapes. Exploring agronomic and environmental barriers, DCB is quantifying biophysical impacts of diversification and investigating if diversified systems impact sustainability indicators compared to non-diverse systems. Related to soils, our team developed a regenerative agriculture spectrum based on four key drivers: tillage, crop density/cover crop intensity, pasture use, and small grains in rotations. This framework allows for better classification of farms across the Corn Belt. Analysis of over 200 soil samples from 31 farms revealed that no-till systems exhibited higher soil organic matter (SOM) and carbon levels than conventional and reduced tillage systems. Post-harvest data collection focused on soil biological health, including a unique soil smell test with farmers to assess whether scent could indicate healthy soils. Groundwater samples were collected throughout 2024, and deep soil cores were processed for analysis. The entomology team concluded its final data collection season, examining the impact of agricultural systems on insect population using pitfall traps, predator assays, acoustics, and eDNA. Ongoing productivity research investigates whether diverse rotations promote weed diversity, natural pest suppression, and crop productivity, utilizing satellite imagery to estimate yields and assess sustainability. Exploring supply chain and market development, DCB is conducting a variety of surveys targeting different portions of the supply chain. Data collection for surveys of wholesalers and restaurants has been completed;results focuson added value for specific produce certifications, price premiums for certified and non-certified labels, and operational data. The team is currently analyzing this data and preparing papers on results. Additional surveys for wineries, retailers, and consumers are underway, alongside a literature review exploring factors influencing procurement decisions from domestic and diverse buyers. In consumer research, a mixed-method study examined oat milk consumption among consumers, focusing on attributes and values influencing purchase decisions. A national survey is being developed to assess consumers' willingness to pay for oat milk with attributes linked to diversified agriculture and various labels. Additionally, the DCB team launched a pilot market initiative with Smithfield Foods to source hybrid rye for feeder pig rations. Rye will be planted in 2024 and harvested in 2025, with insights expected in 2025. OBJ 2: Related to modeling impacts of a more diversified agricultural system, efforts to develop a foodshed model include progress on a collaborative geo-design decision support tool to engage stakeholders in envisioning sustainable and resilient future landscapes. The team also analyzed USDA administrative and land cover data to assess crop diversity on farms managed by the same individuals, identifying clusters of farms with high and low crop diversity. State maps highlighting "hot spots" and "cold spots" of crop diversity in Illinois, Indiana, and Iowa were produced and used in RAD team meetings to inform discussions on enhancing agricultural diversity. We are also quantifying emission actors at a crop and county level to be used in scenario development to quantify reduced air quality related health damages. OBJ 3: DCB is conducting key research in Objectives 1 and 2 to help development stakeholder-informed visions for a more diverse agricultural landscape in the Corn Belt. OBJ 4: The DCB project is actively exploring policy opportunities through objective 1 and collaborating with policy advocates to develop stakeholder-informed policy recommendations to promote a more diverse and resilient agricultural landscape in the Corn Belt. DCB is also engaging in discussions with other SAS-CAP projects with a similar focus, aiming to leverage collective knowledge and resources to strengthen the impact of shared policy recommendations and outcomes. OBJ 5: The DCB team has successfully engaged target audiences through various extension events, including seven presentations at the PFI 2024 Annual Conference with 292 attendees, five presentations at the Midwest Covers and Grains Conference reaching 439 individuals, six field days with 249 attendees, and seven Diversified Rotation Farmer Network Calls involving 167 participants. The DCB team is building relationships with stakeholders throughout the agricultural value chain by introducing project concepts to regional and national audiences. The team is also developing modules related to pesticide label restrictions on rotational crops and forage use, which will be available for private applicator recertification programs administered by Land Grant Extension. Furthermore, DCB has begun developing extension publications for each of the five diversified systems and is collaborating with the communications team to update and expand the resource portal on the project website, ensuring valuable information is readily accessible to stakeholders. OBJ 6: Following the established curriculum structure, the DCB team continues to develop content for educational modules categorized into four diversity units (ecological, agricultural, human, and economic diversity) and three connecting units (systems thinking, changing minds, sustainability principles). The team is recruiting content experts to develop modules and tailoring content for a high school audience. Additionally, planning has begun for a "Midwestern Sustainable Ag Tour" for students and DCB stakeholders interested in hands-on experiences with diversification in the Corn Belt.

Progress 09/01/22 to 08/31/23

Outputs
Target Audience:DCB target audiences include: Farmers; agricultural advisors; landowners; food, fiber, biomass retailers; Land Grant University Extension; policy makers/funders; students; educators; researchers. To broadly reach our target audience, DCB published three newsletters (Winter 2022, Spring 2023, Summer 2023). Newsletters were sent to 500+ individuals and received a 45.9% open rate. DCB also has an active online presence with a website, Facebook, Twitter, and LinkedIn. In this reporting period, DCB tweets totaled 54,685 impressions and DCB appeared in 26 media articles, press releases and other on-line outreach activities gathering 3,715,901 impressions. Changes/Problems:The following changes have occurred Sustainable Food Labs (SFL) (Elizabeth Reaves) has left project. SLF conducted initial interviews with CPGs (see details in accomplishments) and the rest of their work has been delegated to others on the DCB team. Dr. Yichao Rui joined DCB (PI) with Binod Joshi (PhD student). Dr. Rui focuses on processes that underpin soil and crop resiliency and is identifying opportunities where current cropping systems can be implemented withagroecological principlesto improve their performance and long-term sustainability. Dr. Rui's expertise is a valuable addition to the DCB team. Stakeholder coordinator (not initially planned or budgeted) has left DCB and their responsibilities have been delegated to the project manager. What opportunities for training and professional development has the project provided?DCB is providing training and professional development to 4 undergraduate students, 9 graduate students and 4 post-docs. DCB has also supported conference and seminar attendance for PIs, students, post-docs, and staff. How have the results been disseminated to communities of interest?DCB team has shared information and results in over 20 presentations and has published three newsletters to a mailing list of 531 individuals. As results are ready to share in meetings and academic literature, a campaign of press releases, media outreach and social media will amplify the findings to a wide range of stakeholder audiences. What do you plan to do during the next reporting period to accomplish the goals?OBJ 1: To address social and economic barriers, DCB will conduct RAD meetings in IN, IL and IA and establish relationships with CPGs for a national RAD meeting. Data will be analyzed and results will be integrated into related objectives. To address agronomic and environmental elements, DCB will install additional groundwater monitoring wells and continue collecting soil health, insect biodiversity, water quality, and vegetative data from on-farm collaborators across the study area. Y2 data will be analyzed within and across disciplines and incorporated into subsequent tasks and objectives. Related to market development DCB will finish data collection and analysis of surveys targeting key supply chain stakeholders (wholesalers, restaurants, fresh produce buyers, and grocers). We will also conduct consumer-focused research related to preference for a diversified product (oat milk) using interviews to uncover product attributes (e.g., pesticide-free, local, sugar-free, organic, etc.) driving preference and choice. Interviews will inform a nationwide choice experiment survey to assess consumers' willingness to pay for specific attributes. OBJ 2: DCB will continue modeling efforts related to economic and ecosystem impacts of diverse landscape scenarios across the Corn Belt. Models include farm-level economics, land use change, air quality, foodshed, water quality, and agent-based. Models are informed by Obj 1 results and will be the starting point for stakeholder-informed visioning sessions focused on the future of agriculture in the Midwest. OBJ 3: The DCB team will continue gathering data and recruiting participants who will contribute to the stakeholder-informed visioning sessions. OBJ 4: This was originally not intended to occur until Y5 but the DCB team is already exploring policy opportunities and alternatives through engagement efforts in Y3 of the project and sharing research findings directly with policy groups such as AGree. DCB will also continue networking efforts with policy advocates and planning strategies for developing policies that support a more resilient agriculture future in the Corn Belt. OBJ 5: DCB will continue developing relationships with key organizations and stakeholders across the ag value chain to support farm diversification and market development. We will use these relationships to leverage the efforts of our team and support development of organizations who can extend the reach of DCB findings. OBJ 6 DCB will build out and finalize pilot example modules from each unit and reach out to content experts to contribute modules based on their expertise. Modules will be designed at the college level and will be tailored to fit the needs of a high school classroom.

Impacts
What was accomplished under these goals? OBJ1Exploring social and economic barriers to diversification, DCB conducted focus groups, interviews, and Reimagining Agricultural Diversity (RAD) meetings. Focus groups asked participants to share what is working and not working in the current agriculture system. 20 focus groups were conducted with 100 diversified and non-diversified farmers. A manuscript of findings has been submitted to Agriculture and Human Values (Sep 23). Results found challenges and opportunities related to economics and market considerations, particularly income, productivity, and market access. Interviews focused on pathways and barriers faced in diversified operations. 32 interviews were conducted with 36 diversified farmers. Initial findings identified challenges and opportunities related to markets, scale, labor, and support. DCB also conducted the first of many RAD Meeting with 18 participants, including a range of stakeholders (farmers, advisors, landowners, local decision makers and agency staff, etc.). RAD Teams are a long-term stakeholder engagement group that meet to discuss topics through the project and provide feedback on project findings. RAD Teams provide a critical opportunity for researchers to understand perspectives of agricultural stakeholders in the region. The first meeting established a baseline with participants about their thoughts on agricultural diversification and explored needs and visions for the future in an interactive facilitated discussion. DCB conducted a farmer survey in Jan 2023. The survey was distributed to 3300 farmers across the study area and focused on perceptions of diversification, current practices used, and attitudes towards potential future adoption. The survey received a response rate of 23%. Preliminary analysis is underway. DCB is using horizon scanning techniques to gain strategic foresight on future potential for agricultural diversification in the corn belt. Horizon scanning is used to detect early signs of potentially important developments by documenting emerging threats and opportunities. Analysis is underway and a paper is in development. Exploring agronomic and environmental barriers, DCB is quantifying biophysical impacts of diversification and investigating if diversified systems impact sustainability indicators compared to a non-diverse system. We recruited 72 on-farm collaborators and collected soil health, insect biodiversity, water quality and vegetative data from cropping systems ranging from highly diverse to non-diversified. The first season of data collection is complete. DCB conducted soil fertility analysis and shared results with on-farm collaborators to inform management decisions for the 23/24 season. DCB installed 24 wells on a range of landcover to measure water table fluctuation and water quality. Pitfall traps were used to assess insect biodiversity, predator assays to quantify pest control, and acoustic monitoring to measure insect community dynamics. DCB performed weed surveys and estimate pest pressure and natural enemy activity. Data analysis/synthesis, and planning for next season is underway. DCB is also characterizing cropping systems and developing a "diversification index" to uniformly classify participating fields. Exploring supply chains and markets development, DCB is conducting 4 surveys targeting supply chain stakeholders (wholesalers, restaurants, fresh produce buyers, and grocers). Surveys focuses on food purchasing practices, local sourcing, sustainability initiatives, marketing strategies, perspectives on diversification, required sustainable labels/claims, and demographics. The wholesaler and fresh produce buyer surveys are currently underway. Based on preliminary results, wholesalers are primarily motivated by financial benefits and managing price volatility, with a strong interest in local and sustainable products. While diversified farm products are not a major part of their portfolios, wholesalers' express intent to increase sourcing from these farms in the future. Survey development for restaurants industry, and grocers is underway. DCB is conducting case studies of diverse products and has conducted 26 interviews with oat, wheat, and pea growers in to identify market challenges, opportunities, and success factors. DCB conducted 7 interviews with CPG companies to explore opportunities and challenges to sourcing diverse ingredients. Results indicate the easiest strategy to bring regenerative products into their portfolio is to purchase smaller brands (i.e. General Mills purchasing Epic, Pepsi purchasing Sabra), additionally we recommend supporting events for start-ups to promote regenerative products to CPGs. Furthermore, collaboration between R&D, Marketing, and Procurement is essential for successful ingredient switches. Smaller companies can be more agile, but partnering with established regenerative brands aids in effective pilot testing and marketing strategies. OBJ 2: DCB is building a database of information on crops and other land uses at the USDA farm administrative unit level. This analysis will increase our understanding of where crop diversity exists and does not exist in today's landscape and can speak to common conditions enabling or disabling diversification across the Corn Belt. DCB has updated the 2014 model for the air quality-related health damages from US food system allocated to specific commodities to incorporate the 2020 National Emissions Inventory from US-EPA. With updated model, we created state specific figures showing health damages per corn production at a county level. We recorded and ideated on changes to the model required for the future diverse scenarios we anticipate from the modeling and RAD Teams in the coming year. DCB team has developed a modeling schematic to outline the workflow and inputs/outputs for agent-based, landscape, farm-level economic, air quality, food shed, and SWAT models. OBJ 3: DCB is conducting key research in obj 1 and 2 to inform the development of visions of a more diverse agricultural landscape in the Corn Belt. OBJ 4: DCB has been exploring policy opportunities and alternatives through obj 1 activities. We are strategizing with policy advocates to develop policy guidance to support a more diverse and resilient agriculture landscape in the Corn Belt. OBJ 5: DCB has engaged target audiences through a variety of extension events across the study area, including 2 PFI Cooperators Meetings, 11 presentations at the PFI 2023 Annual Conference with 849 attendees, 5 presentations at the Midwest Covers and Grains Conference reaching 439 individuals, 8 Field days with 347 attendees, 8 Diversified Rotation Farmer Network Calls with 213 participants. Additionally, the DCB team is developing relationships with stakeholders across the agricultural value chain by introducing the project concepts in the Corn Belt and nationally. OBJ 6: DCB continues to develop education curricula to foster the development of a workforce prepared to address emerging social and agricultural challenges and support more diverse agricultural landscape. DCB established a structure including four diversity units (ecological, agricultural, human, and economic) with 36 modules and three connecting units (systems thinking, changing minds, principles and sustainability) with 20 modules. Addressing all objectives, PIs generated $1.55 million dollars with 3 additional grants that will support and extend DCB efforts. Additional grants include 1. "Dollars and Sense - Diversifying the Agricultural Landscape with Climate Smart Commodities that Make Both" from the UIUC Institute for Sustainability Energy and the Environment 2. USDA-NIFA funded Integrated Midwest Partnerships for Actionable Climate Tools and Trainingfocused on developing resources for diversified systems in a changing climate, and 3. USDA-NIFA Organic Transitions grant assessing soil health in organic cropping systems across Indiana to identify environmental and management drivers.

Outputs
Target Audience:DCB target audiences include: Farmers; agricultural advisors; landowners; food, fiber, biomass retailers; Land Grant University Extension; policy makers/funders; students; educators; researchers. To broadly reach our target audience DCB published two press releases to the media. Upon receiving the grant, DCB published a press release through Purdue University "Purdue awarded $10 million for #DiverseCornBelt project". This press release achieved 25 media placements and reached a total audience of 439,355. To recruit participants and raise awareness of the project, DCB published the press release "Diverse Corn Belt Project Seeks Farmer Input". This press release achieved 19 mentions in conventional and social media and generated 1.41 million impressions. DCB also broadly promoted project activities and concepts through two radio interviews and one podcasts. WGLT: (https://www.wglt.org/local-news/2022-08-22/diverse-corn-belt-project-will-explore-agronomic-and-economic-benefits-of-transformed-crop-rotations) FarmWeek: https://www.farmweeknow.com/eedition/page-a14/page_6d5e Purdue Ag Week, The Future of Ag podcast - Regenerative Agriculture and Diverse Corn Belt - https://podcasts.apple.com/us/podcast/sustainability-and-regerative-ag-with-michael/id1561692455?i=1000552005331 To target Cooperative Extension, an overview of DCB was shared with the Purdue Extension's Agriculture and Natural Resources team and Diversified Food and Farming Systems team in February, 2022. To target students, DCB team members have supported four undergraduate mentees and have done one guest lecture in an undergraduate class. Changes/Problems:The following changes have occurred Evaluator change: Our project evaluator has changed from Bets McNie to Jean Eells. Citing unforeseen circumstances, Bets stepped down as DCB's evaluator and we have recruited Dr. Jean Eells of E Resources Group to fill the role. Dr. Eells brings a strong evaluation skill set as well as a contextual knowledge of the current agricultural landscape. Stakeholder coordinator hire: A portion of salary designated for extension efforts has been reassigned to support a stakeholder coordinator working on a number of different objectives and reporting to the project PD. The individual had specific skills and experience relevant for this project but the position had not been included in the budget. Their presence on the DCB team is integral to accomplishing short and long-term goals. Co-PD change: Mike Komp left the position of Executive Director of Conservation Technology Information Center (CTIC) in August 2022. Ryan Heiniger joined CTIC as Executive Director in November and assumed Komp's role on the DCB project. Co-DP addition: Dr. Shadi Atallah has joined the DCB team as a Co-PI from University of Illinois. Dr. Atallah will lead the development of an agent-based model (ABM) of a #DiverseCornBelt. The ABM will feature farmer-agents making decisions to adopt alternative farming systems. Adoption decisions will be based on a choice experiment survey with farmers in the Corn Belt in which farmers will be asked to make hypothetical farming system adoption decisions as a function of market characteristics, adoption by neighbors, and interventions by Extension, and policy. We will use the ABM to model the causes and effects of farming system diversification from the farm to the landscape level and the associated economics environmental, and social outcomes. What opportunities for training and professional development has the project provided? Nothing Reported How have the results been disseminated to communities of interest?DCB team has shared information and results at a total of 10 presentations. What do you plan to do during the next reporting period to accomplish the goals?To address objective 1 in year 2, DCB will launch and begin analyzing surveys developed in year 1 (farmers, retailers, and buyers), continue gathering data from participants via interviews and focus groups, and convene DCB's Reimagining Agricultural Diversity (RAD) teams, our long-term stakeholder engagement and visioning group of diverse stakeholders. We will also begin data collection for our on-farm research. To address objective 2 goals, DCB team will continue modeling efforts related to economic and ecosystem impacts of diverse landscape scenarios across the Corn Belt. Objective 3 will not begin until year 3 but the DCB team will continue gathering data and recruiting participants who will contribute to the stakeholder-informed visioning sessions Objective 4 will not occur until year 5 but the DCB team will continue exploring policy opportunities and alternatives through engagement efforts in year 2 of the project. DCB will also continue networking efforts with policy advocates and planning strategies for developing policies that support a more resilient agriculture future in the Corn Belt. To address objective 5 goals in year 2, the DCB team will continue developing relationships with key organizations and stakeholders across the ag value chain to support farm diversification and market development. We will use these relationships to leverage the efforts of our team and support development of organizations who can extend the reach of DCB findings. To accomplish objective 6 goals in year 2 the DCB team will continue development and testing of learning modules for secondary and undergraduate levels. These learning modules will be adaptable and accessible to large learning communities and will prepare the next generation of farmers and ag stakeholders to address emerging challenges and support a more diversified landscape.

Impacts
What was accomplished under these goals? In our first year the Diverse Corn Belt team has made considerable progress establishing a foundation for project success. Progress includes administrative accomplishments, stakeholder engagement, and cross-project collaborations. DCB has hired two key positions (Project Manager and Regenerative Ag Coordinator), recruited five graduate students, one post-doc, and established project infrastructure enabling multi-institution and interdisciplinary data sharing, communication, and research. We have convened two in-person All Team meetings (project kick-off meeting in January 2022, and annual meeting in June 2022), and established sub-teams working on project objectives. Both full-team and sub-teams meet monthly (virtual) to discuss progress, updates, and needs. To promote DCB to stakeholders across the Corn Belt we have developed a DCB brand that includes a logo, website, and presentation templates. The website includes key DCB information and updates, and will house DCB products and information throughout the life of the project. DCB has conducted 11 farmer focus groups to understand baseline conditions of attitudes towards diversification and to establish a foundation for knowledge, attitude, and behavior change in the coming four years. Objective 1: Coproduce research and advance market development along the agricultural value chain to identify and address social, economic, agronomic, and environmental barriers to the adoption of diverse sustainable agricultural systems. To address objective 1 the DCB team conducted 11 focus groups in IN (7), IL (2), IA (1) with 53 participants. Participants included diversified farmers (66%), not diversified farmers (19%), and non-farmers (15%).Non farmers included consultants, advisors, lenders, and educators. The focus groups gathered information from about their farming operation, perceptions of agricultural diversification, and what is working and not working withing the current system. Findings highlighted social, economic, agronomic, and environmental barriers and opportunities for a more diversified agriculture system. The focus groups also helped DCB identify farmer cooperators interested in participating in future DCB activities, specifically DCB's Reimagining Agricultural Diversity (RAD) teams, a long-term stakeholder engagement and visioning group. The DCB team is developing field work protocols for biophysical data collection and recruiting participants for on-farm data collection. This work will characterize the conditions and extent to which a diversified system impacts indicators of biophysical sustainably, compared to non-diversified system. Biophysical measures include soil health, insect biodiversity, and water quality. To explore market development across the agricultural value chain, DCB is developing surveys for produce growers, retailers, and buyers. To inform survey development, the DCB team is interviewing key market players and conducting a literature review focused on market standards and preferences related to regenerative farming products. The team is also conducting case studies of diverse products to understand how markets develop and perspectives of growers, buyers, and consumers. To further understand farmer perceptions of opportunities and barriers to a more diverse agricultural system, DCB is developing a farmer survey that will be administered to diversified and non-diversified farmers across the Corn Belt. Data from this survey will inform objectives 1, 2, and 3. Objective 2: Model economic and ecosystem impacts of diverse landscape scenarios across the agricultural value chain to develop evidence-based policy recommendations, quantify sustainability metrics and establish conditions required for economic vitality. DCB has identified three watersheds to assess the impacts of diverse cropping systems in the Corn Belt (Middle Des Moines in Iowa, Middle Wabash in Indiana, andEmbarras in Illinois). The Soil and Water Assessment Tool (SWAT) ecohydrological model will simulate cropping systems and management practices that represent both traditional row crop production versus alternative cropping methods. A SWAT model has already been constructed for the Des Moines River Basin forIowa Urban FEWS, an NSF-funded project. This SWAT model will be leveraged for future DCB cropping system simulations and other relevant analyses. Considerable testing of the model has already occurred. Additional testing and scenario analyses will be conducted within the NSF project that will provide a firm foundation for DCB applications. The DCB team is also developing a spatial and temporal analysis of farm crop and land cover diversity at USDA's Economic Research Service using restricted USDA administrative data. This analysis combines land parcel boundaries with the same operator to increase our understanding of where crop diversity exists and does not exist in today's landscape. This analysis also identifies biophysical or socio-economic factors correlated with both diversity and lack of diversity. This analysis helps DCB identify a baseline of where diversity already exists on the landscape and will be able to speak to common conditions enabling or disabling diversification across the Corn Belt. Objective 3: Design stakeholder-informed alternative production systems by conducting visioning sessions at the local, state, and national levels that allow participants to consider ethical choices and sustainability outcomes. Although objective 3 is planned to occur in years 4 and 5 of the project, the DCB team is conducting key research in objectives 1 and 2 to inform the development of future scenarios of alternative production systems. Objective 4: Develop and disseminate policy guidance to achieve resilient intensification through diversified farms, landscapes, and markets. While objective 4 is planned to occur in year 5 of the project, the DCB team has been exploring policy opportunities and alternatives through the coproduction efforts occurring in objective 1. We are also networking with policy advocates and planning a strategy to develop effective policy guidance to support a more diverse and resilient agriculture future for the Corn Belt. Objective 5: Engage with diverse stakeholders through Extension to support farm diversification and market development. The DCB team has been developing relationships with stakeholders across the agricultural value chain by introducing the project and project concepts in the study region and nationally. Objective 6: Create, pilot, and publish educational materials to foster a workforce prepared to respond to emerging challenges and support a diversified landscape. The DCB education team has been developing teaching education modules at the high school and college level. This curriculum will support the development of a workforce prepared to address emerging social and agricultural challenges and support more diverse agricultural landscape. This team meets monthly to discuss pedagogy for learning modules and convened a day-long in-person meeting with the Univ of MN's Center for Educational Innovation to identify student learning outcomes and establish a framework for DCB learning modules.
