Abstract	Climate-related stresses are altering the conditions under which crops are selected, cultivated, conserved, and exchanged. Drought, irregular rainfall, heat episodes, flooding, new pest pressures, and changing seasonal patterns can increase the vulnerability of farming systems that depend on a narrow range of crop varieties. Community seed networks provide a decentralized mechanism through which farmers can conserve, exchange, evaluate, and recirculate locally adapted crop genetic resources. Rather than treating seeds solely as commercial inputs, such networks recognize them as biological resources embedded within local knowledge, social relationships, environmental histories, and collective adaptation processes. This study develops a community-centered analytical framework for examining the relationship between seed-network strength, crop diversity, and agricultural resilience under climatic stress. Because no original farmer-level dataset was supplied, the study uses a transparent simulation-based comparative design. Two hypothetical seed-system conditions are evaluated: fragmented local seed access and an organized community seed-network model. A synthetic sample representing 300 hypothetical farming households was constructed across different levels of climatic exposure, farm resource availability, seed accessibility, and crop-diversity dependence. Five dimensions were evaluated: crop-variety diversity, seed availability during climatic shocks, local adaptation compatibility, recovery capacity, and agricultural knowledge exchange. The simulated results indicate consistently stronger performance under the community seed-network model. The composite performance score increased from 52.0 under fragmented seed access to 82.4 under an organized network, representing a modeled difference of 30.4 points. Knowledge exchange and recovery capacity showed particularly large modeled gains. These outcomes illustrate how community networks may contribute to agricultural adaptation not simply by storing seed but by maintaining dynamic processes of seed circulation, farmer experimentation, variety evaluation, knowledge transfer, and collective risk sharing. The paper argues that community seed networks should complement, rather than replace, formal breeding programs, certified seed channels, public genebanks, and agricultural extension. Sustainable seed-system policy should connect formal and farmer-managed systems while protecting varietal diversity, seed quality, farmer participation, and equitable access. The numerical results are illustrative and require empirical field validation. Nevertheless, the proposed framework offers a reproducible basis for future studies examining how locally managed seed diversity may strengthen cropping-system resilience under increasing climatic uncertainty.
