The Stone Dike Technology: Innovation that Helps Mitigate Soil Erosion in the Gullies

Mahintana Foundation, Inc., continues to think outside the box in the conservation, preservation and protection of the environment particularly around the Mt. Matutum Protective Landscape (MMPL). To mitigate the soil erosion that usually occur in the plantation gullies, the organization innovated a technology that uses indigenous materials found in the locality such as large rocks, used fishnets from the fishing industries in General Santos City, and malabago trees, thus, the birth of the stone dike technology. The technology was purposely constructed in scoured gully banks to prevent their further damage.

The ceremonial construction of the stone dike was conducted on August 10, 2018 at Gully 116A/101C, Upper Klinan, Polomolok, South Cotabato as one of the activities of the 41st anniversary celebration of Mahintana and SRC. From its construction to present, the stone dikes were able to allow sedimentation that increased the vegetation around the dikes and stabilized the gully banks by protecting them from further scouring. Other stone dikes were constructed in 110A/109C Cannery and 113C/112B/113B Polo.
