How could the Tigris and euphates rivers be both helpul and harmful?

The Tigris and Euphrates rivers are vital for agriculture, providing essential water resources for irrigation in a predominantly arid region, which supports food production and sustains populations. However, they can also be harmful as they are prone to flooding, which can devastate communities and infrastructure. Additionally, the rivers are sources of geopolitical tension, as countries sharing their waters may compete for access and control, leading to conflict. Thus, while they are crucial for livelihoods, their management poses significant challenges.
