dredging

Norfolk Island’s unique corals face a triple threat from disease, El Niño, and government-approved dredging. Scientists warn that sediment and pollution from cattle farming, cleared land, and wastewater contribute to coral disease and algae outbreaks.

Dredging in Korapuzha river is set to resume after being halted in February 2026 due to mass protests. Residents and political parties had accused authorities of using dredging as a pretext for illegal sand extraction.
