According to the Food and Agriculture Organization of the United Nations (FAO), Eritrea's TRWR stands at approximately 6.3 km³ per year. In contrast, Egypt's TRWR is about 66.8 km³ per year.
𝐂𝐨𝐧𝐭𝐫𝐢𝐛𝐮𝐭𝐢𝐨𝐧 𝐟𝐫𝐨𝐦 𝐄𝐭𝐡𝐢𝐨𝐩𝐢𝐚
Both Eritrea and Egypt rely on external renewable water resources (ERWR) from Ethiopia. Eritrea receives about 3.5 km³/year, while Egypt receives an estimated 58.3 km³/year.

The percentage of Eritrea's surface water resources originating from Ethiopia can be calculated as:
Percentage=( ERWR/TRWR )×100= (3.5/6.3)×100≈55.6%
This means that approximately 55.6% of Eritrea's total renewable water resources come from rivers originating in Ethiopia.
𝑭𝒐𝒓 𝑬𝒈𝒚𝒑𝒕:
The percentage of Egypt's surface water resources that come from Ethiopia can be calculated using the formula:
Percentage=( ERW R/TRW R )×100= (58.3/66.8)×100≈87.3%
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 Tekezé 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.
𝗙𝗶𝗻𝗮𝗹 𝗡𝗼𝘁𝗲: 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.
