Iraq's water quota. to which it has been accustomed for hundreds of years. has been affected by water pollution. the lack of sufficient water for agriculture. damage to the water environment of the marshes. the decline of the agricultural and animal sector. the spread of diseases and Population migration due to the lack of respect by the upstream countries for the (Tigris. Euphrates. Karkha. Yund. Mandali. Karon) and many other tributaries because there are no binding int`l water agreements without the consent of states regulating how to exploit these rivers to ensure their continuation and share their water fairly and fairly in line with the established int`l rules represented by the Helsinki Rules ( int`l river basin concept ) and the convention on the protection and use of watercourses (UNECE) and the convention on the law of the non-navigational uses of int`l rivers ( int`l watercourse concept) and the int`l applications of these conventions. which supports Iraq's arguments in obtaining its reasonable and equitable water share. similar to the countries bordering int`l rivers around the world. Therefore. the research will focus on studying these three agreements and reviewing int`l applications on them and making a trade-off between them. any of which guarantees the interests of Iraq. paving the way for reaching realistic proposals that can be adopted by Iraqi specialists when negotiating with upstream countries of rivers that cross the Iraqi borders. as described in the research plan.
