The problem being complex, the solution is also a combination of interventions that should be anchored on science and drawn after scientists have studied the Cagayan River itself, after they have walked its banks, felt its current, followed its meander, and seen it in its ebbs and flows. Vegetation removal can also result in changing the ground and surface water conditions, which may be important in triggering landslides.
