The future of our food supply may lie in the past. As climate change intensifies and modern agricultural practices prioritize yield over diversity, a growing movement is focusing on the preservation of “old seeds” – heirloom varieties that hold a wealth of genetic information potentially crucial for adapting to an uncertain future. These seeds, often overlooked in favor of commercially optimized hybrids, are gaining recognition for their unique properties and resilience.
Experts like Felix Dominik, a plant expert at the Botanical Gardens of the University of Bonn, emphasize that while not every old variety is essential, each possesses “individual properties” that could prove invaluable. “If there are yield failures, you can simply use the properties of another variety to continue breeding and continue to have a yield,” Dominik explained. This approach to safeguarding agricultural biodiversity isn’t simply nostalgic; it’s a pragmatic strategy for building a more resilient food system.
The Decline of Variety in Modern Agriculture
The shift towards specialized, high-yield agriculture has dramatically reduced the diversity of crops available to consumers. The Federal Agency for Agriculture and Food (WDR) reports that while approximately 2,000 apple varieties were known in Germany in the mid-19th century, only around 30 remain commercially relevant as of 2024. This narrowing of genetic diversity makes our food supply more vulnerable to pests, diseases, and the impacts of climate change.
Hybrid seeds, engineered for high yields and visual appeal, dominate commercial agriculture. However, these seeds typically don’t breed true – meaning their seeds cannot be saved and replanted to produce the same characteristics. This dependence on purchasing new seeds each season creates a cycle that diminishes farmers’ autonomy and further erodes genetic diversity. In contrast, “seed-true” varieties, often the older types, can be naturally pollinated and reproduced, preserving their unique traits across generations.
Seed Libraries and the Growing Movement for Preservation
The effort to preserve plant diversity extends beyond research institutions and botanical gardens. A growing network of hobby gardeners and even libraries are actively involved in collecting, sharing, and propagating old seeds. In Neuss, Germany, a seed library allows residents to “borrow” regionally adapted varieties for non-commercial use, with the understanding that they will return a portion of the harvest as seed for future generations. “The idea behind the loan is to preserve the diversity of crops for a more sustainable life,” explains Claudia Neufurth, the librarian responsible for the seed library in Neuss.
This grassroots movement complements the work of experts like Dominik, who manages around 2,000 crop plants at the University of Bonn, three-quarters of which are edible. While acknowledging the benefits of commercial seed breeding for professional agriculture, Dominik emphasizes that his work focuses on preserving options for the future – safeguarding varieties whose strengths may become crucial in the face of changing environmental conditions.
The Importance of Seed Saving for Future Resilience
Maintaining plant diversity requires consistent sowing and seed collection. “The seeds don’t last forever. That is, if we miss sowing them and they eventually lose their germination capacity, the variety may be lost,” Dominik cautions. The preservation of these genetic resources is not merely about maintaining a historical record; it’s about building resilience into our food systems. The diverse traits held within these old seeds could provide the key to developing crops that are more resistant to drought, pests, and other challenges posed by a changing climate.
The preservation of plant genetic diversity is gaining political recognition as well, highlighting the importance of these efforts for long-term food security. As the world faces increasing environmental pressures, the wisdom of investing in the past – by safeguarding the seeds of the future – is becoming increasingly clear.
