Mindanao’s Life Source
The Mindanao River Basin is the second largest river system in the Philippines, and the largest in Mindanao. Located in the Central and a portion of Southern Mindanao, it has a total catchment area of 21,503 km2.
It covers the area from the mountains of Impasug-ong in Bukidnon (known as Upper Pulangi River), Kabacan River (relabeled as Mindanao River), Lower Pulangi River and Ligawasan Marsh. The latter serves as natural flood storages, from which the river system splits to the Tamontaka and Rio Grande de Mindanao Rivers and finally exits to Illana Bay.
The area covered by the MRB has a total population of 3,533,086 from three (3) regions: Region X, XII and ARMM; and five (5) provinces: South Cotabato, North Cotabato, Sultan Kudarat, Bukidnon and Maguindanao.
This strategic location of MRB enables it to provide water resources critical to the socio-economic development not only in the basin but to the whole island of Mindanao as well.
The basin was divided into sub-basins for the purpose of the MRB project study. Its re-definition resulted into twenty (20) sub-basins summarized in the table below, including the Buayan-Malungon, which was an extension of the MRB study.

The issues and concerns that are currently faced by the basin include flooding, siltation and sedimentation, watershed denudation, riverbank erosion and water pollution from domestic and agricultural sources. In order to address these issues, the MRB Management Council (MRBMC) was formed.
“A Mindanao River Basin that is a sustainable area of peace and development where all stakeholders, striving as active collaborators and competent stewards of the Almighty Creator, adhere to the judicious use of its natural resources to enjoy non-discriminatory socio-economic growth, human development and ecological balance that is inclusive for all and without aggression to anyone or anything.”
“Ensure a focused, comprehensive and integrated development and management of the Mindanao River Basin that would prevent, mitigate and protect its inhabitants and stakeholders from any calamities and disaster risks, and facilitate the attainment of sustainable development.”
