West African fisheries, climate change, and aquaculture: A World Bank and Sub Regional Fisheries Commission workshop

West Africa may be one of the most vulnerable regions to climate change. The region is highly dependent on fisheries for livelihoods and as an important food source. The marine resources of West Africa are currently threatened by overfishing and climate change-induced ocean warming could see fish stocks migrate away from the area and into cooler waters. If CO2 emissions continue at their current levels, the region could see a 50% decline in fisheries-related jobs and a total annual loss of US$311 million, found a study by Nereus Program researchers.

Nereus in the News – Friday, November 4

“Emptying seas, mounting tensions in fish-hungry Asia” was published yesterday by Nikkei Asian Review. It discusses the state and future of oceans and fisheries in Asia, with increasing demand yet overfished stocks, and features insights by Nereus Director of Policy Yoshitaka Ota.

Big data and fisheries management: Using satellites to track fishing activity

“After climate change, fishing is the biggest impact humans will have on the oceans. But we have very a limited understanding of what happens beyond the horizon. It’s out of sight,” says David Kroodsma, Global Fishing Watch Research Program Manager at SkyTruth. “Global Fishing Watch allows us to see where the fishing is happening and how much. This will lead to whole hosts of answers to questions about how we manage our oceans.”

Instability in the South China Sea: Ecosystem challenges and political complexities

One of the most significant – and increasingly bitter – international disputes of recent years has engaged legal claims over maritime territory in the South China Sea. Under the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), to which the main protagonists are parties, states are entitled to claim an Exclusive Economic Zone (EEZ) conferring sovereign rights and jurisdiction up to 200 nautical miles of maritime space from their coasts. In the South China Sea, however, this position has been complicated by historical claims over a series of small islands and reefs within the southern section of this area.

Five key aspects of sustainable aquaculture: Can aquaculture help tackle global food security, especially in Africa?

by Muhammed Oyinlola, Nereus Fellow

Aquaculture, the farming of aquatic species, is gradually becoming an important aspect of solving the challenge of global food security. The supply of seafood from fisheries is declining; fish stocks can only be increased if we reduce our fishing pressures, yet governments continue to subsidize the fishing industry for us to fish more. Hence, the open window we have is aquaculture. My argument is that we need to change from hunting in the ocean to farming the oceans just the way we changed hunting on land to producing animal protein by farming. Can aquaculture be our best option to increase the seafood supply for the world’s ever increasing population?

Climate change effects on illegal, unreported and unregulated fishing

A range of human pressures is threatening the sustainability of marine fisheries. Amongst those, overfishing, partly driven by Illegal, Unreported and Unregulated (IUU) fishing, is a major stressor. Thirty percent of global fish catch goes unreported, found a recent study by Nereus Program collaborator Sea Around Us.

But the relationship between IUU fishing and climate change is a new topic. I speculate that climate change impacts on fisheries may indirectly increase IUU fishing.
