Farmers are responding by adopting more resilient crop varieties, adjusting planting and harvesting schedules, and investing in irrigation and drainage infrastructure. However, these adaptations require financial resources and technical knowledge, and the unpredictable nature of jet stream-driven weather makes long-term planning challenging.
