Abasin irrigation
Bqanats
Cperennial irrigation
Dfertigation
Eorographic precipitation



Question 2:

What is happening to the water supply of North Africa and Southwest Asia?

AIt is declining, mostly due to population growth and new modern uses.
BIt is increasing, as the deserts recede.
CIt is declining, mostly due to evaporation.
DIt is increasing, due to population decline and water rationing.

Verified Answer :

Final answer:

Before the Aswan Dam, Egyptian agriculture utilized basin irrigation, relying on seasonal floods from the Nile. Currently, water supply in North Africa and Southwest Asia is declining primarily due to population growth and modern water usage. This decline increases competition for limited water resources in the region.


Explanation:

Question 40: Traditional Egyptian Irrigation

Prior to the construction of the Aswan Dam, much of Egyptian agriculture relied on a traditional system known as basin irrigation. This method involved creating basins to hold water from the Nile River, which would then flood and irrigate crops. Basin irrigation was particularly effective for growing crops such as wheat and barley in ancient Egypt, as it depended on seasonal flooding to replenish soil moisture.

Question 41: Water Supply in North Africa and Southwest Asia

The water supply in North Africa and Southwest Asia is currently declining, mostly due to population growth and new modern uses. Rapid population growth has increased demand for water, coupled with modern agricultural practices and industrial uses that require significant water resources. This situation exacerbates existing water scarcity issues faced by many countries in the region, resulting in increased competition for limited water supplies and leading to potential conflicts over water resources.
