to 34.2% in 2017 . There is high confidence that reducing stresses on marine ecosystems reduces vulnerability to climate change and augments resilience . Specifically, overfishing is the most critical non-climatic driver affecting the sustainability of fisheries, and therefore improving management could help rebuild fish stocks, reduce ecosystem impacts and increase the adaptive capacity of fishing ; . Pursuing sustainable fisheries practices under a low-emissions scenario would decrease risk by 63%; in contrast, under the most extreme RCP8.5, both profit and harvest decline relative to today even under the most optimistic assumptions about global fisheries management reforms .
