Climate change could increase fishing fuel consumption

We know that fuel use contributes to climate change, but in a vicious circle, climate change could also increase fuel use in fishing. This is due to fish shifting their distributions due to warming waters. With this increased use of fuel and the increasing price, small-scale and artisanal fishers will have a harder time sustaining livelihoods and feeding their families under climate change.

Mangroves, fisheries, and community livelihoods: Conducting fieldwork in Indonesia

Mangrove forests, made up of shrubs and trees with sprawling roots that grow in salt water, provide many services to humans and marine ecosystems. They sequester carbon, pulling it from the atmosphere, and prevent erosion of coastal areas. Due to their unique characteristics, mangrove forests provide an important source of food and shelter for marine species, including many important fisheries. Mangroves cover 150,000 km² of coastline in tropical and warm temperate regions around the world. Rachel Seary, Nereus Fellow at Cambridge/UNEP-WCMC, is currently conducting research to understand both the direct benefits that mangroves have on communities living and fishing within their vicinity and also the indirect benefits that mangroves may have on coastal fisheries productivity in Bali, Indonesia.

Climate change-contaminant interactions in marine food webs

This paper proposes that climate change will alter the effects of pollutants in marine food webs by either directly increasing contaminant exposure (for instance due to receding ice caps), or making organisms more vulnerable to other climate change impacts. It discusses two main classes of contaminants that can affect the health of marine organisms: fat-soluble contaminants known as persistent organic pollutants (POPs), and protein-binding contaminants such as methylmercury (MeHg).

Side Event at the UN Ocean Conference Preparatory Meeting

The Nereus Program facilitated a side event on February 16 entitled: “Co-Benefits of Achieving SDG Goal 14 to Wider SDGs: Prioritizing Action Given Climate Change and Social Inequity”. The theme of the event was implications of changing oceans on the advancement of SDG’s, with an emphasis on the co-benefits of achieving ocean targets on other environmental, economic, and social equity goals.

Managing living marine resources in a dynamic environment: The role of seasonal to decadal climate forecasts

Variations in climate lead to fluctuations and changes in fish stocks; they can have effects on such things as fish behaviour, distributions and growth. Because of this, fisheries management has to respond dynamically to these fluctuations. If management decisions are made primarily on past patterns, the negative impacts can be exacerbated, especially with climate change.

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.

Climate, Anchovy, and Sardine

According to the FAO, anchovy and sardine made up 13% of global catch in 2012. These small fish are consumed by humans, marine mammals, seabirds, squid, and other fish. They are also used for aquaculture feed, industrial oil, and health supplements. “Climate, Anchovy, and Sardine” a new study in the Annual Review of Marine Science, co-authored by Nereus Alumni Rebecca Asch (Princeton University) and Ryan Rykaczewski (University of South Carolina), reviews the past, present, and future of anchovy and sardine.
