Using Drones to Monitor Coastal Erosion in Ghana

“Delta environments are low-lying and highly vulnerable to flooding and erosion by ocean waves. And these hazards are likely to increase as the world’s climate changes and sea levels rise. Monitoring these hazards, and their impacts, is very important to develop strategies and protect communities living close to deltas.

Drones can be a key tool for this work. My colleagues and I used drones to monitor flooding in Fuvemeh, a vulnerable coastal community in Ghana’s Volta delta. The Volta delta, located along the eastern coast of Ghana, is a hot spot for erosion and flooding.

Even though the frequency and intensity of floods and erosion has increased in recent years, there’s a lack of early warning systems and effective monitoring which doesn’t allow vulnerable communities to be prepared.

One reason for this are the traditional methods of flood monitoring, like aerial photos and ground surveying, which can be very expensive and need specialised training. Drones, on the other hand, are low cost and easy to operate. They give quality, high resolution outputs, and can be deployed fast and often…”
