Forest Concessions and SUDECOR

A critical component of the Tago River’s watershed management involves the role of forest concessions, specifically the area managed by the Surigao Development Corporation (SUDECOR). The SUDECOR forest concession area is situated within the watershed, playing a vital role in the conservation of the headwaters and the broader forest cover that feeds into the river system. Forest concessions in the Philippines are typically long-term leases granted to corporations to manage and develop forest lands, often balancing timber production with conservation efforts. In the case of the Tago River, the SUDECOR concession helps regulate land use in the upper reaches of the watershed, influencing sediment load, water retention, and biodiversity.

The headwaters of the Tago River, located in the forested highlands of Sibagat and the adjacent areas in Surigao del Sur, are essential for maintaining the river’s flow regime. The forest cover in these headwater areas, including the SUDECOR concession, acts as a natural sponge, absorbing rainfall and releasing it gradually into the river. This process helps mitigate flooding during the wet season and ensures a steady water supply during the dry season, which is crucial for the irrigation projects managed by the National Irrigation Administration. The health of the forest concession area directly impacts the river’s ecological health, affecting fish populations, water clarity, and the overall resilience of the watershed to climate variability.

Management of the SUDECOR forest concession involves balancing economic activities, such as timber harvesting and agro-forestry, with environmental conservation goals. Effective management practices in the concession area can enhance the watershed’s capacity to filter pollutants, reduce soil erosion, and maintain habitat connectivity for wildlife. Conversely, poor management can lead to deforestation, increased sedimentation in the river, and reduced water quality, which can negatively impact downstream communities in Tago and San Miguel. The coordination between the National Irrigation Administration and the forest concession managers is therefore essential for the integrated management of the Tago River watershed, ensuring that water resources are sustainably utilized for both ecological and human needs.
