A breakthrough study published in Nature Food by Prof. Wang Shuo, a key member of Otto Poon Research Institute for Climate-Resilient Infrastructure, reveals that rising global temperatures are fueling "snow droughts" that threaten global food security.
Winter wheat relies on snow cover for insulation and moisture. Using an innovative machine learning framework (XGB-SHAP), Prof. Wang’s team found that snow droughts now affect 70–99% of Northern Hemisphere croplands (up from 46–54% in the 1960s), with 45% of these areas suffering significant yield losses.
Pathways to Climate Resilience
To safeguard global food systems against this growing climate risk, the study calls for an urgent shift toward climate-resilient agricultural practices:
- Climate-Smart Crops: Breeding winter wheat varieties with dual tolerance to both extreme cold and drought.
- Precision Farming: Transitioning from fertilizer-heavy practices to sustainable nutrient management to reduce crop vulnerability.
- Early Warning Systems: Integrating satellite snow-cover monitoring into agricultural risk assessments to help farmers proactively adapt.
"As global warming accelerates, we must shift from reactive crisis management to proactive, climate-resilient agricultural planning," says Prof. Wang.
This research underscores Otto Poon Research Institute for Climate-Resilient Infrastructure’s commitment to pioneering scientific solutions that strengthen global climate resilience and protect sustainable development.
