How does increased vulnerability to pests and diseases relate to climate change?

Increased vulnerability to pests and diseases is closely related to climate change as it can indeed decrease crop yields. Climate change can create conditions that are more favorable for pest and disease outbreaks, such as higher temperatures, changes in precipitation patterns, and increased humidity. These environmental shifts allow pests and pathogens to thrive and expand their geographic range, potentially invading areas where crops were previously healthy and productive.

As crops become stressed due to these changes, their natural defense mechanisms may weaken, making them more susceptible to infestations and infections. When crops are affected by pests and diseases, their ability to grow and produce food is compromised, leading to reduced yields. This cascading effect highlights the critical link between a changing climate and agricultural productivity challenges, illustrating the importance of understanding how climate impacts food security and agricultural systems.
