Pulangi River

The Philippines is endowed with an extensive network of rivers that meander through its more than 7,000 islands. These rivers, such as the Cagayan, Davao, and Agusan, play a crucial role in the country's diverse ecosystems and are integral to the lives of its people. They provide essential irrigation for agriculture, supporting the cultivation of rice, corn, and other crops that are staples of the Filipino diet and economy. In addition to their role in agriculture, these rivers are important for transportation, especially in remote areas, and are a source of hydroelectric power.
