Presentation Description/Abstract
Russia's invasion has degraded Ukraine's chornozem through three interacting pathways: physical disruption, chemical contamination, and biological decline. Armor traffic, trenching, and cratering compact soils, bury topsoil beneath subsoil spoil, and reduce infiltration. Impact sites may contain munitions metals, explosive residues, and petroleum products, while microbial abundance and enzymatic activity have declined in heavily disturbed areas. Although contamination is often localized, large areas remain unsuitable for immediate agricultural use.
This poster proposes a restoration framework organized by site access and safety rather than by a fixed timeline, allowing recovery to begin before active hostilities cease. The framework uses layer-matched restoration, pairing each damage pathway with targeted interventions. Physical recovery combines root-based bio-drilling by drone-seeded pioneer species, followed after demining by low-ground-pressure autonomous subsoiling and topsoil restoration along trench corridors. Chemical recovery employs compost-based treatment of explosive residues, fungal remediation of petroleum contamination, biochar and bone char for metal immobilization, and non-food phytoremediation guilds. Biological recovery focuses on indigenous fungal inoculation, community-derived compost inputs, and rebuilding soil food webs.
Implementation proceeds through access-based phases: remote assessment and seeding on unsafe mined ground, robotic fragment removal and targeted remediation in restricted-access zones, and soil reconstruction and agricultural testing once sites are cleared. Recovered land is ultimately triaged into three pathways: agricultural production after verification and testing, Miyawaki-style native forest thickets that stabilize damaged areas and support biodiversity, and crater-derived infiltration basins that enhance groundwater recharge and partially offset irrigation losses associated with the destruction of the Kakhovka reservoir system.
