The Impact of Climate Change on Global Agriculture
Climate change poses significant threats to global food security by altering agricultural productivity and crop yields.
Key Findings
- Rising temperatures reduce wheat and maize yields in tropical regions.
- Increased frequency of extreme weather events disrupts planting cycles.
- Shifts in precipitation patterns affect water availability for irrigation.

Adaptation Strategies
Farmers are adopting drought-resistant crop varieties and implementing precision irrigation techniques to mitigate climate impacts.
$\Delta Y = \beta_0 + \beta_1 T + \beta_2 P + \epsilon$
| Region | Average Yield Change (%) |
|---|
| Sub-Saharan Africa | -12.5 |
| Southeast Asia | -8.3 |
| North America | +2.1 |
