5 Thesis Topics on Coastal Erosion and Dredging in the Philippines

Source: GMA News Online

Let me convince you to make this a thesis.

You worked abroad for 45 years, saved every cent, and built a small resort by the sea. It was supposed to be your dream, your retirement, your legacy. But in just three hours, the waves swallowed three meters of your land. Seven newly built cottages gone. The beachfront that was once 70 meters wide is now barely ten. The sea keeps coming closer, and there is nothing you can do.

This is not just about one man’s loss. It’s a bigger, silent disaster. Beach erosion is destroying livelihoods. Resort owners blame dredging ships stealing sand at night, but officials call it a natural cycle of erosion and accretion. There are no storms, no typhoons. Just a coastline retreating fast, with no one truly accountable. The gap? We do not have enough solid data to link human dredging to rapid coastal erosion. We do not know how much of this is natural and how much is man-made. And without that knowledge, solutions will come too late.
