The Impact of Climate Change on Global Agriculture
Climate change poses significant threats to global agricultural systems. Rising temperatures, altered precipitation patterns, and increased frequency of extreme weather events are disrupting crop yields and livestock production worldwide.
Key Impacts
- Reduced water availability for irrigation due to changing rainfall patterns.
- Increased prevalence of pests and diseases affecting crops.
- Soil degradation from prolonged droughts and intense flooding.

| Region | Current Yield (tons/ha) | Projected Yield (tons/ha) |
| North America | 5.2 | 4.8 |
| Europe | 4.5 | 4.1 |
| Asia | 3.8 | 3.2 |
