What makes for a successful climate-resilient fishery, one that sustainably produces resources for human benefit despite increasing climate stressors and human impacts? It's a question that faces present and future fisheries, their practitioners and fishing communities as the world turns to the ocean to feed its growing population.
"For a fishery to be resilient it needs to be able to prepare for, resist, cope with, recover from, or adapt to any given impact," said Jacob Eurich, who is a research associate at UC Santa Barbara's Marine Science Institute, and a fisheries scientist at the Environmental Defense Fund ."In most cases a fishery will need to have a combination of these capacities to continue to produce food, income and well-being to the people who rely on them.
Fortunately, there are climate resilience success stories to draw lessons from. To gain these valuable insights, Eurich and colleagues examined 18 fisheries that expand our knowledge about how resilience operates across the world. "The biggest challenge is that every fishery is different," Eurich said."Each fishery has different characteristics and operates on different scales, for different reasons and with unique goals."
This system allowed the researchers to find strengths and commonalities to which other fisheries under similar circumstances may align to increase their own resilience.The researchers developed five archetypes of climate-resilient fisheries and detailed two pathways to climate resilience. They found that in some fisheries,is derived from strong ecological assets and tight-knit communities that promote flexible governance, despite having limited economic avenues outside of fishing.
