Identifying the Purpose of a Researcher's Discussion

In the following passage, a researcher discusses the impacts of climate change on agricultural productivity:

'Recent studies indicate that climate change has led to significant shifts in weather patterns, resulting in decreased yields for many crops, particularly in tropical regions. Additionally, the variability in rainfall has made it increasingly difficult for farmers to plan their planting and harvesting schedules. As these challenges mount, it is imperative for agricultural experts to explore innovative farming techniques that could help mitigate these effects. These techniques might include drought-resistant crops, improved irrigation systems, and sustainable farming practices.'
