Manupali River
Also known as: Ilog Manupali · Manupali watershed (for the research catchment)
Definition
The Manupali River is a river in central Bukidnon on the island of Mindanao, Philippines, rising on the slopes of the Kitanglad and Kalatungan ranges and flowing east to join the Pulangi River, the main headstream of the Rio Grande de Mindanao. Its watershed, centered on the Valencia and Lantapan area, has been extensively studied as a model research catchment for tropical agriculture and watershed management.

Examples and Analogy
The Manupali works like a middle lane of Mindanao’s great water highway: it gathers rain from two high mountain ranges and hands it to the Pulangi, which carries it to the Rio Grande and the sea, the way a county road feeds a national highway, with farms and towns strung along its banks.
Usage Scenarios
The river irrigates rice and corn lands around Valencia City and Lantapan, supplies water to communities, and supports inland fishing; its watershed hosts long-running research on soil conservation, agroforestry, and river monitoring by Philippine universities and international programs.
Strategies
Watershed planners combine riparian buffer zones, contour farming on steep slopes, and reforestation of upper tributaries to moderate floods and siltation, while local governments enforce easement rules along the banks and monitor water quality at stations established under the research programs.
Security and Safety Measures
Flash floods sweep down the Manupali after heavy rain on the Kitanglad range, so communities maintain warning systems and avoid river activities during storms; steep eroded banks make crossing outside established fords and bridges hazardous.
Historical Context
The river valley was opened to widespread farming in the twentieth century as Bukidnon became a corn and rice powerhouse, and settlement pushed cultivation onto steep slopes. From the 1990s onward the watershed became one of the Philippines’ most studied catchments, with the Sustainable Agriculture and Natural Resource Management program and successor projects using it to demonstrate how upland conservation protects downstream farms and households.
Challenges and Controversies
Soil erosion from cultivated slopes, fertilizer runoff, and flooding in low-lying Valencia remain chronic concerns, and debates continue over balancing upland livelihoods with watershed protection. Sedimentation ultimately threatens the Pulangi hydropower plants downstream, linking farm practices on the Manupali to Mindanao’s electricity supply.
