A desert country which has a high population density supported by irrigation is?

The country that has a high population density supported by irrigation is Egypt. Egypt is located in the northeastern part of Africa and is mostly covered by desert. However, the Nile River flows through the country, making it possible to irrigate land and grow crops. The population density in Egypt is high, especially in the Nile River valley and delta, where the fertile land is concentrated. The country has invested heavily in irrigation infrastructure, including dams, canals, and other irrigation systems, to support agriculture and food production.
