摘要

Meeting global food demands by 2050 requires a 45–60% increase in agricultural production. Plasticulture has emerged as a pivotal yet controversial solution. Here we perform a meta-analysis synthesizing the findings of global studies and reveal that plastic mulch enhances crop yields by 28.7% and water use efficiency by 48.9% under diversified systems. In China (2015–2024), plasticulture contributed an additional 189 million tons (Mt) of staple food, conserved 33.5 million hectares of arable land, and reduced emissions by 438 Mt CO₂-equivalent. However, persistent plastic residues degrade soils, and nanoplastics infiltrate food chains, posing ecological and health risks. Despite global negotiations (2024–2025), a binding UN treaty on plastic pollution remains stalled due to disparities among players. To reconcile productivity with sustainability, we propose six evidence-based priorities: (1) scaling integrated eco-farming systems with AI-driven precise application of soil mulches; (2) accelerating material innovation, focusing on biodegradable films and organic-based alternatives; (3) deploying blockchain-enabled circular economies for plastic waste; (4) improving reuse and recycling infrastructure; (5) implementing localized incentive mechanisms to support plastic-free farming; and (6) integrating plastic management into UN carbon trading frameworks. These strategies can pivot plasticulture toward a climate-resilient, ecologically sustainable model—balancing food security with environmental stewardship in an era of climate uncertainty.
