According to the Food and Agriculture Organization of the United Nations (FAO), Eritrea's TRWR stands at approximately 6.3 kmยณ per year. In contrast, Egypt's TRWR is about 66.8 kmยณ per year.

Both Eritrea and Egypt rely on external renewable water resources (ERWR) from Ethiopia. Eritrea receives about 3.5 kmยณ/year, while Egypt receives an estimated 58.3 kmยณ/year.

๐ญ๐๐ ๐ฌ๐๐๐๐๐๐:
The percentage of Eritrea's surface water resources originating from Ethiopia can be calculated as:
Percentage=( ERWR/TRWRโ )ร100= (3.5/6.3)ร100โ55.6%
This means that approximately 55.6% of Eritrea's total renewable water resources come from rivers originating in Ethiopia.
๐ญ๐๐ ๐ฌ๐๐๐๐:
The percentage of Egypt's surface water resources that come from Ethiopia can be calculated using the formula:
Percentage=( ERW R/TRW Rโ )ร100= (58.3/66.8)ร100โ87.3%
This indicates that approximately 87.3% of Egypt's total renewable water resources are sourced from Ethiopia.
In summary, rivers originating from Ethiopia play a significant role in the water resources of both Eritrea and Egypt. For Eritrea, the Mareb and Tekezรฉ rivers contribute about 55.6% to the country's total renewable water resources.
These rivers are crucial for various aspects of Eritrea's development, such as agriculture and hydropower. On the other hand, nearly 87.3% of Egypt's total renewable water resources come from the Blue Nile river in Ethiopia. This river is vital for Egypt's agriculture, drinking water supply, and also holds cultural and historical significance.
๐๐ถ๐ป๐ฎ๐น ๐ก๐ผ๐๐ฒ: The percentage is derived from the total water volume that flows into a country, rather than from the individual rivers. So even if multiple rivers contribute to Egypt's renewable water resources, the overall percentage originating from Ethiopia will remain the same as long as the total volume doesn't change.
In my article, mentioning the individual rivers like the Blue Nile, Atbara, and Sobat adds depth and context. It helps readers understand the various pathways through which Ethiopian waters reach Egypt.
But, as I pointed out, the key statistic of approximately 87.3% of Egypt's renewable water resources coming from Ethiopia is based on the total volume, not the individual rivers.๐๐๐๐๐ซ๐๐ง๐๐๐ฌ
