How does climate change primarily necessitate change in agricultural practices?

The necessity for change in agricultural practices due to climate change stems mainly from the requirement to adapt to altered crop yields. Climate change can significantly impact temperature, precipitation patterns, and the frequency of extreme weather events, which in turn affect how well crops can grow in specific regions.

Farmers must respond to these changes by adjusting their practices, which may include selecting different crop varieties that are more resilient to heat and drought, altering planting and harvesting schedules, and implementing new pest and disease management strategies. The variability in climatic conditions can lead to reduced yields for certain crops in some areas while potentially increasing yields in others, making adaptation essential for maintaining food security and agricultural productivity.

While pest populations can be influenced by climate change, it is not the sole or primary factor necessitating a change in agricultural practices. Similarly, climate change tends to create less predictable weather rather than more predictable conditions, further emphasizing the need for adaptive strategies in farming.
