International rivers are waterways that flow through or along the borders of two or more countries. These rivers are crucial for various purposes, including transportation, agriculture, and drinking water supply. Examples of international rivers include the Nile, Amazon, and Danube, which support millions of people and diverse ecosystems. Managing international rivers often requires cooperation between countries to address issues like water rights, pollution, and conservation. Treaties and agreements, such as the United Nations Watercourses Convention, help nations work together to ensure sustainable use and protection of these vital resources for future generations.
