Which region is currently experiencing an ongoing drought exacerbated by climate change and El Niño?

The Horn of Africa is indeed experiencing an ongoing drought that has been exacerbated by climate change and the El Niño phenomenon. This region has been particularly vulnerable due to a combination of factors, including reliance on rain-fed agriculture, recurring climatic events, and socio-political instability, all of which have been intensified by climate change.

The drought in the Horn of Africa has led to severe food and water shortages, affecting millions of people and leading to crisis situations such as malnutrition and displacement. Climate change has altered rainfall patterns, making it more unpredictable and contributing to the severity of the drought conditions. Additionally, El Niño events can disrupt weather patterns, leading to prolonged dry spells in certain areas while causing excessive rainfall in others. This combination significantly impacts agricultural productivity and the region's overall resilience.

While other regions mentioned may also experience drought conditions, the Horn of Africa is currently facing one of the most critical situations influenced by these climatic changes, making it the correct choice in this context.
