Lack of rain in hot places like Indonesia and Australia will cause drought
Dams that force the water to change direction are what control the flow of the Nile river. These dams can bring water to areas affected by drought and are prized by the Egyptian people.
Implementing sustainable water resource management practices, such as rainwater harvesting, constructing water storage facilities like dams, and promoting drought-resistant crop varieties can help mitigate the impact of drought in Africa in the long term. Additionally, investing in irrigation systems and promoting efficient water usage in agriculture can contribute to long-term solutions for addressing drought in the region.
