Research Background and Problems

• Problems or Challenges:
  • Current production and consumption models exhibit socially and ecologically destructive externalities, particularly evident in global supply chains.
  • Challenges faced by Community Supported Agriculture (CSA): the need to transcend traditional market mechanisms for fairer resource allocation; how to reconcile consumer demands with constraints of local agricultural production.
  • Lack of innovation in collaboration mechanisms within and between CSA communities, especially in resource sharing and exchange.
• Significance:
  • Covid-19 exposed the vulnerabilities of global food production and exchange systems, emphasizing the importance of localized, resilient, and quality-driven food production.
  • CSA aims to provide an alternative to address inequities and unsustainable practices in traditional food systems.
• Research Motivation and Related Work:
  • The study seeks to explore the role of solidarity principles in mediating consumer demands and agricultural outputs, and further investigate how currency mechanisms can support internal demand coordination and external collaboration within CSA.
  • Reports limitations in existing research, particularly the insufficient attention to CSA and currency interactions within the sustainable HCI domain.

Solutions

• Main Methods or Solutions:
  • Through participatory observation research, using Germany's Luzernenhof CSA as a case study, analyzing the operational principles of solidarity.
  • Luzernenhof employs a Google Spreadsheet-based order and distribution system, along with a self-created "Luzerne" currency unit representing order quantities, to offer consumers customized product orders on demand.
• Innovations:
  • Introduced a "non-market" exclusive currency (Luzerne) to avoid traditional market price interference in value distribution, encouraging consumers to shift from a "shopping mindset" to a "community cooperation" perspective.
  • Achieved a higher trust-based allocation mechanism within the CSA community, allowing consumers to flexibly customize order quantities, forming an "unlimited share size" operational model.
  • Supported high-trust relationships between consumers and farms through non-mandatory recommended payment amounts to ensure system sustainability.
• Implementation Steps and Technologies:
  • Order management is conducted through Google Spreadsheets: farms adjust product availability and pricing based on inventory and demand.
  • Regularly provide payment recommendations to farm members, who decide final payment amounts based on Luzerne order records.
  • Qualitative discussions on the introduction of Distributed Ledger Technology (DLT) to explore broader collaboration potential among CSA networks.

Research Outcomes

• Specific Outcomes:
  • Defined and distinguished three key characteristics of the Luzernenhof model: free product selection, unlimited share size, independent pricing system (Luzerne).
  • The system alleviated the traditional CSA issue of insufficient responsiveness to consumer demands in resource allocation while maintaining ecosystem stability.
  • The introduction of Luzerne currency eliminated potential unfair payment behaviors among members, enhancing community trust and participation.
• Advantages Over Existing Solutions:
  • Compared to traditional "equal shared benefits" CSA models, Luzernenhof's solution improved members' freedom of choice and resource utilization.
  • Reduced market competition-induced inequalities through a cashless, non-market currency system.
• Experimental or Evaluation Results:
  • Field observations of Luzernenhof's system revealed high adherence to recommended payment amounts among members, with no "free-rider" behaviors observed.
  • The system demonstrated significant resilience during Covid-19, particularly in situations of resource shortages or logistical constraints.
• Limitations and Future Directions:
  • The current system heavily relies on Google's technical support; service disruptions pose high risks.
  • Trust challenges exist when expanding cooperative networks (e.g., resource allocation and exchange among multiple CSAs), requiring a balance between fairness and efficiency.
  • Future research directions include developing cross-community collaboration software, exploring solutions based on Distributed Ledger Technology, and continuing to study the relationship between currency innovation and community building.
