Millet Urban Farming for Climate Resilience: A Soilless Rooftop Solution in Japan

Urban Farm DB summary

A paper proposes a soilless rooftop urban farming model for Japan, a space-constrained country, using climate-resilient Ragi (finger millet) and Pearl Millet grown in grow bags, combined with rainwater harvesting, QR-code traceability, and biofortified microgreens. The model incorporates recent epigenetic findings linking environmental stress to heritable gene expression to improve stress tolerance without genetic modification, and is described as youth-friendly, scalable, and aligned with organic farming principles.
