Aquatic weeds are threats to hydro power, water transport - Maritime Authority

Aquatic weeds are spreading rapidly in Ghana’s inland waters. This poses a threat to hydroelectric power and water transport. The Kpong Hydroelectric Power Plant in Akuse is particularly affected.

Dr. Kamal-Deen Ali, Director-General of the Ghana Maritime Authority, emphasizes the need for coordinated efforts. He calls for better collaboration between the Volta Lake Transport Company Ltd and the Volta River Authority (VRA). The VRA manages both the Akosombo and Kpong dams.

Dr. Kamal-Deen made these comments during a weed-clearing inspection at Kpong. This visit was part of the Inland Water Assessment Mission. It included reviewing work done by skimmer vessels that support cleanup efforts.

He noted that tons of weeds have been cleared, allowing power generation to continue. “If not produced, it could cripple the nation,” he told Joy News.

Weed removal is vital for Ghana’s blue economy, according to Dr. Kamal-Deen. It benefits energy production but also supports fisheries and tourism. Weeds can ruin attractions if they choke waterways.

Additionally, clearing weeds allows safe passage for canoes and other boats. Dr. Kamal-Deen expressed satisfaction with partnerships among stakeholders to enhance the inland water economy. These efforts align with the government’s 24-hour economy agenda in lakeside communities.

Since receiving skimmer vessels over two years ago, tons of aquatic weeds have been removed. The cleared biomass contributes to a growing circular economy.

“There’s a company processing weeds into compost,” Dr. Kamal-Deen explained. Some compost is sold while some is given free to local farmers. In some areas, weeds even serve as livestock feed, showing their economic value.

Currently, two skimmer boats operate at Kpong and one at Ada. However, new specifications may be needed for better performance.

On safety, Dr. Kamal-Deen stressed ongoing clearance operations are essential. “As long as the weeds grow, we’ll keep clearing them,” he said about transport risks from ferries or canoes.

Inter-agency cooperation between the Ghana Maritime Authority, VRA, and Volta Lake Transport Company is expected to strengthen further.

The site visit was led by Angela Oforiwaa Alorwu-Tay from Volta Lake Transport and Hakeem Tijani from VRA along with their teams.
