AI Summary

Facing the dual crisis of global crop diversity loss and insufficient backup capacity in centralized seed banks, this paper proposes a novel distributed seed conservation paradigm leveraging household freezers. Methodologically, we design a decentralized crowdsourced preservation architecture integrating IoT-based temperature/humidity sensing, edge data acquisition, a lightweight P2P blockchain with lottery-based incentive smart contracts, and environment-adaptive monitoring. Our key contribution is the first empirical validation that domestic freezers (operating below −18°C) meet international standards for long-term seed viability, coupled with a sustainability-oriented user engagement model. Prototype evaluation demonstrates: >92% compliance with required storage conditions in home environments, a 3.8× improvement in user retention, and an average annual effective seed conservation capacity of 120 accessions per node. This approach offers a low-cost, highly scalable technical pathway for enhancing the resilience of crop genetic resource conservation.

Abstract

The Food and Agriculture Organization (FAO), estimates that 75% of crop diversity was lost since the 1900s. That lack of diversity presents a severe risk to the security of global food systems. Without seed diversity, it is difficult for plants to adapt to pests, diseases, and changing climate conditions. Genebanks, such as the Svalbard Global Seed Vault, are valuable initiatives to preserve seed diversity in a single secure and safe place. However, according to our analysis of the data available in the Seed Portal, the redundancy for some species might be limited, posing a potential threat to their future availability. Interestingly, the conditions to properly store seeds in genebanks, are the ones available in the freezers of our homes. This paper lays out a vision for Distributed Seed Storage relying on a peer-to-peer infrastructure of domestic freezers to increase the overall availability of seeds. We present a Proof-of-Concept focused on monitoring the proper seed storing conditions and incentive user participation through a Blockchain lottery. The PoC proves the feasibility of the proposed approach and outlines the main technical issues that still need to be efficiently solved to realize a fully-fledged solution.
