Community seed banks make a genuine contribution to climate-resilient farming, but their reach remains limited to relatively small segments of farmers, according to a comparative study of 17 seed banks across Ethiopia, Malawi and Nepal published this month in the journal Frontiers in Sustainable Food Systems.
The research, led by Regine Andersen, Viviana Meixner Vásquez and Ola T. Westengen among eleven contributing authors from institutions across the three countries, examined five seed banks in Ethiopia, five in Malawi and seven in Nepal using a comparative, qualitative case study approach, work also summarised by the Nepal-based research organisation LI-BIRD.
Seeds in time for planting, not just in storage
The study’s central finding is that community seed banks function as more than passive storage facilities. Where they work well, they provide farmers with “quality seeds of climate-resilient crop varieties in time for planting,” paired with training in techniques suited to changing local conditions, a combination researchers found more valuable to farmers than genetic conservation alone. That timing element matters directly: seed that arrives after the planting window has closed is of little use regardless of how well it has been preserved.
The researchers also documented cases where seed banks function as genuine sites of agricultural innovation, describing some as platforms where professional plant breeders and farmers jointly develop and refine crop varieties. That collaborative model, blending formal breeding science with farmer knowledge of local growing conditions, represents a more dynamic role than the traditional image of a seed bank as a static repository of heirloom varieties.
A scalability problem, not a design flaw
Alongside those positive findings, the study is candid about limitations. It notes that “the number of CSBs are limited, the numbers of members and farmers served by the CSBs vary,” meaning the model’s benefits are concentrated among the communities lucky enough to have an active, well-run bank nearby. The researchers also found that not all desired varieties remain consistently available across the 17 banks studied, and that some genetic erosion, the gradual loss of less-popular varieties, has occurred even within banks designed specifically to prevent it.
Taken together, the findings position community seed banks as a genuinely useful but structurally modest tool: valuable where they exist and are well managed, but currently reaching only a fraction of the smallholder farmers across Ethiopia, Malawi and Nepal who could plausibly benefit from more reliable access to climate-resilient seed.
Implications for policy and funding
The study’s authors argue the findings carry a clear policy implication: rather than treating community seed banks as a finished solution, governments and donors should treat scaling and consistent funding as the primary unresolved challenge. That framing echoes concerns raised elsewhere in the region, including at India’s Chizami seed bank in Nagaland, where organisers have relied on grassroots women’s societies rather than sustained government backing to keep their collections viable.
With climate variability continuing to erode the reliability of conventional seed supply chains across Ethiopia, Malawi and Nepal, the researchers suggest that expanding the community seed bank model, rather than simply celebrating existing examples, will determine whether it becomes a mainstream part of climate adaptation strategy or remains a valuable but marginal intervention.
The 17-bank sample size is itself a reminder of how early-stage this evidence base remains: with community seed banking practised informally in many more locations than have been formally studied, the researchers note that comparative, cross-country research of this kind is still relatively rare, limiting how confidently findings from Ethiopia, Malawi and Nepal can be generalised to other climate-vulnerable farming regions without further study.
