Adaptation strategy          

Explanation:

For more than 20 years, scientists have been analyzing expected climate change and the impact on crops grown in particular regions. For example, states that typically plant corn and soybeans may need to switch to growing cotton. Such a change is an example of adaptation. As the word implies, farmers will have to adapt to new climatic conditions so as to keep producing their crops. Adaptation strategies aims at increasing resilience to climate change. Examples of climate change adaptation strategies involve the cultivation of more drought tolerant crops, compared to maize and soybean, cotton is more drought tolerant.
