1.5 °C temperature increase will put small-scale fisheries at high risk: IPCC Special Report October 10,2018   |  Source: ICSF

A new report by the Intergovernmental Panel on Climate Change (IPCC) unequivocally states that not limiting global warming will drive small-scale fisheries well below the sustainable harvesting levels required to maintain fisheries resources and food security.

The Special Report on the impacts of a 1.5 °C warming above pre-industrial levels, approved by the IPCC on 6th October, extensively describes the risk to fisheries and aquaculture as a result of such an increase in temperature. Small-scale fisheries in tropical regions, the report states, are at a high risk by an increase of 1.5°C, mainly due to loss of habitat.

“Risks of impacts and decreasing food security become greater as warming and acidification increase, with substantial losses likely for coastal livelihoods and industries (e.g. fisheries, aquaculture) as temperatures increase beyond 1.5°C,” states the report.

While moderate risk to ocean food webs are projected under present-day conditions, the levels of risk would begin to rise by 1.1°C, intensifying ocean acidification, the loss of coral reefs, sea level rise, and rapid shifts in the distribution of marine species. Threats to four major species groups are highlighted: pteropods and small molluscs (important links in the food web between
