This is an internal challenge for the Agriculture Research Service (ARS), United States Department of Agriculture (USDA). Team leaders must be an ARS scientist or post-doctoral researcher.

The theme for ARSX2022 is the Circular Economy in Agriculture.  We are looking to make a paradigm shift from a linear to a circular economy. Your ideas will transform our approach from linear processes that take starting materials and end up with products and waste streams to integrated processes in a circular economy that take starting materials and produce products and starting materials for other processes.  By developing regenerative processes and closing gaps in existing loops, we can use our natural resources more efficiently.

This challenge will award up to three teams submitting the most compelling proposals up to $100,000 each to demonstrate proof of concept for their ideas.  If you’ve had a bold and/or unconventional idea in this area in the back of your mind, now is the time to act!  

In ARSX2022, the teams submitting the 10 most compelling ideas will be selected as Phase 1 winners (finalists).  These teams will have several weeks to participate in an innovation forum, to refine their ideas, and to build out their pitches.  At the end of Phase 2, finalists will present their pitches to a panel of judges and an audience of their peers and colleagues.  The judges will award up to $100,000 each to the top three teams.

In addition to the three $100,000 prizes, this challenge offers participants a chance to build new relationships across disciplines and geographies, and Phase 1 winners will have access to both group and individual pitch coaching.




This challenge is open to ARS personnel only.  Team leads/captains must be scientists or post-doctoral researchers.

External collaborators are permitted only on ARS-led teams. Please see the Rules section below.


Restoring our Planet with Circular, Sustainable, Agriculture and Food Systems

Advances in U.S. food and agricultural systems since the 1930s have quadrupled the supply of food and fiber.  These increases have been driven by improvements in genetics, agronomy, mechanization, and other innovations, but they have come at a cost to our environment and our planet’s overall health. We now recognize the importance of ensuring that our agricultural practices are sustainable - for example through performance of life cycle analyses or through maintenance of soil health.  But we need to do more.  A 2021 report notes that “the food system is responsible for 21-37% of total net anthropogenic greenhouse gas emissions when including pre- and post-production activities” (Pörtner, H.O., 2021).  Successfully addressing the challenges arising from climate change and other environmental concerns will require a paradigm shift in agricultural and food systems from linear processes to a circular economy (Basso, B. et al, 2021). ARSX2022 is all about sharing your ideas to help build this emerging circular economy in agriculture.

To highlight the timeliness of this year’s ARSX topic, the U.S. Environmental Protection Agency (EPA), U.S. Food and Drug Administration (FDA) and U.S. Department of Agriculture (USDA) recently renewed their joint agency agreement on reducing food loss and waste, and the Biden-Harris Administration issued a factsheet in September 2021 focused along similar lines. This current interest and awareness presents opportunities for those with high-risk, high-reward research proposals that will ultimately support the necessary paradigm shift to achieve circular agriculture systems. 

The opportunity for circular systems in agriculture includes technologies and practices to retain and regenerate soil health, increasing the nutrition density of our foods while not compromising taste and sensory experience, integration of traditional waste from food production back into the ecosystem or as useful co-products, and more. Solutions that can employ a circular systems paradigm can reincorporate materials through the entire production and supply chain and provide a sustainable and resilient agriculture system needed to meet the goal of zero waste agriculture.   

A circular economy is a complex, dynamic, and highly integrated thing.  Many different elements must come together to successfully achieve the whole.  We believe each of you may have an idea that can become part of those necessary elements.  Approaches like those listed below will all contribute to an emerging circular economy in agriculture.

  • Regenerating natural systems by controlling finite sources and expanding renewable resource flows
  • Optimizing yields with reduced external inputs for production and keeping materials in the technical or biological cycles for as long as possible
  • Designing processes to reduce or eliminate pollution and waste from production and consumption

Ready to learn more about the ARSX experience?  Then read on.  If you are uncertain about this year’s theme or just want a little more inspiration, click on the Ways to Contribute to the Circular Economy document in the Resources section.  There you’ll find some questions to help get your creative juices flowing.  This list of ideas and suggestions is not intended to be limiting or prescriptive.  So if you have an idea that defies categorization, we want to hear about it!

Be part of ARSX2022 - The Circular Economy in Agriculture and submit your ideas.  Participation in ARSX2022 is open to any ARS scientist or post-doctoral researcher.  We’re always interested in creative and impactful ideas that are rooted in science, but this challenge seeks to encourage bold, aspirational, and high risk ideas.  Think of this as an opportunity to test out your idea - it might be the start of something great, or it might fail smart and fast.  Either way, ARSX offers a new path for uncommon scientists and their uncommon ideas.  If you can draw a line from your idea to how it will ultimately enable a circular economy within agricultural activities, then this challenge is for you!  (Hint, we believe this challenge is for all of you and can engage all the national program areas of ARS.)  


How did previous ARSX participants benefit from the process?

Previous ARSX awardees all cite the ability to connect and collaborate with other ARS scientists across diverse geographies and disciplines as one of the top benefits.  We hear repeatedly that ARSX gave individuals an opportunity to build teams and work with those that they wouldn’t normally.  Many teams plan to continue their collaborations into future research endeavors.  Whether participants, finalists, or awardees - they all appreciate the opportunity to pursue different ideas with different collaborators.  Another aspect of ARSX that gets a lot of positive feedback is the pitch coaching that finalists receive.  This training in non-technical pitching is an opportunity to build skills that can be essential to successfully communicating your ideas and projects.

The ARSX2021 visionaries all approached greenhouse gas reductions in different ways, but every team mentioned the pleasure of building new teams and having a place to pursue different ideas.  Bryan Emmett, Claire Phillips, Ryan Hayes, Rod Venterea, and Florence Sessoms won for their approach to developing biological nitrification inhibition (BNI) in cover crops as a cost-effective and climate-resilient N2O mitigation solution.  They noted so many positive aspects of participating in ARSX.  In addition to team building and pitch coaching, they also enjoyed being able to use the ARSX platform as a way to develop and further their idea and being able to engage with ARS administrators.  Dan Martin and his team proposed a novel technique to enhance rainfall from convective clouds by releasing electrically charged water droplets into clouds.  They were thrilled to have been selected as one of the three ARSX2021 winning teams, but what they really valued was the journey through the competition process.

The three winners of ARSX2020 had very different approaches for keeping disruptive agricultural pests and pathogens at bay, but they all appreciated an opportunity to get their ideas - ones that might only be tangentially related to their regular research projects - out in the open.  ARSX2020 Visionaries Robert Shatters, W. Rodney Cooper, and Michelle Heck used their winnings to support automation and greenhouse and laboratory evaluations of their Plant-Host Activated-Cell Transplantation (PHACT) technology at four different USDA sites.  They appreciated how the ARSX process promoted team building across multiple disciplines and helped develop a sense of camaraderie among the team members.  The team attributes part of their success in applying for and winning a $15 million NIFA SCRI ECDRE grant to the strong team building that occurred during the process of participating in ARSX2020.  As a result of his ARSX award, ARSX2020 Visionary Vincent Ricigliano was nominated to receive a young investigator’s award and was invited to submit a proposal for a grant based on his idea for feed-based therapeutics.

If you are selected as one of the 10 finalists, you will be invited to participate in the ARSX2022 Innovation Forum.  This will be your opportunity to refine and strengthen your idea by getting input from relevant subject matter experts, by possibly building out your team to address gaps, and by receiving both individual and group pitch coaching.  At the end of the Innovation Forum and training period, you will pitch your idea to a panel of judges and an audience of your peers and colleagues.  The judges will select up to three winners, and each winner or winning team will receive up to $100,000 to demonstrate proof of concept for their ideas.  Depending on the outcomes from initial work on winning ideas, there is the possibility for some of them to become funded research projects.

The goal of ARSX is to encourage ideas and collaborations that are outside the box and possibly quite early stage, so your ideas will be evaluated primarily based on their potential impact and overall novelty.  Secondary criteria include feasibility and collaboration.  See the Judging Criteria section for more details.



Up to 10 Phase 1 finalist teams will be eligible to participate in an innovation forum to refine their original ideas, build out their teams, and receive pitch coaching.  This is a unique opportunity to interact with colleagues from other parts of the organization, to get visibility within ARS, and to develop some new skills.

Up to 3 Phase 2 winners will each receive up to $100,000 to support proof of concept work on winning ideas.

Additionally, all participants will benefit from the ARSX experience.  Submitting your idea to ARSX2022, will afford you the following:

  • Opportunity to get your idea reviewed by experts outside of ARS (external evaluation panelists include experts, entrepreneurs, and innovators with perspectives that are outside of agriculture)
  • Visibility both within and outside of ARS
  • Additional funding opportunities from the Innovation Fund Panel that are only open to ARSX2022 participants
