Overview
A column proposing the transition to climate-resilient agriculture triggered by the 2025 rice shortage.
## Key Points
### 1. Reality of the "Reiwa Rice Riots"
- 2025 rice harvest: 7.4 million tons (-15% from normal year, third worst postwar crop failure)
- Causes: Record heat (July-August average temperature 30.2°C) and water shortage
- Rice price surge: 18,000 yen per 60kg (+45% YoY)
- Emergency rice imports: 500,000 tons (largest scale ever)
### 2. Impact of Climate Change on Agriculture
- Heat damage: First-grade rice ratio 45% (historic low, normal 70%)
- Pest damage: Brown planthopper damage area 3.2 times previous year
- Water resources: Western Japan dam storage rate 58% (-20 points from normal)
- Northward shift of suitable areas: Rice cultivation suitable areas shifted 100km north in 10 years
### 3. Specific Measures for Transition
- Variety improvement: Accelerating development of heat-resistant varieties (target 30% adoption rate for "Niji no Kirameki")
- Smart agriculture: 30% water reduction through AI water management
- Crop conversion: Support for switching to heat-adapted crops (olives, avocados)
- Infrastructure development: Investment in drought-resistant irrigation systems (3 trillion yen over 10 years)
The article recommends treating this rice shortage not as a temporary problem but as a turning point toward sustainable agriculture.
