Small-Scale Fisheries in the Colombian Pacific: Understanding the Impact of Climate Change on Fishermen's Livelihoods

While few have contemplated the potential impacts of climate change on small-scale fisheries and fishermen in the Colombian Pacific, understanding these effects is crucial for devising effective adaptation strategies. This study presents the outcomes of a vulnerability assessment related to climate change for fishermen in the Colombian South Pacific. The assessment employed a multivariable model that considered the sensitivity of marine and coastal ecosystems that support fishing resources alongside fishermen's adaptability to changes in the biophysical environment. Socioeconomic factors were also scrutinized. The study revealed that 80% of the surveyed fishermen are at a medium to high level of vulnerability due to changes in the distribution of key commercial species, which influences the productivity of their traditional fishing sites. Their vulnerability is primarily attributed to low usage of fishing technologies, the boat engine's limited propulsion capacity, and a lack of diversity and sustainability in fishing gear. These elements increase their reliance on fishing sites close to the coast (approximately 3 km to 5 km from the shoreline), resulting in a low adaptive capacity for the fishermen. The dominant factor driving the sensitivity component was the economic significance of the fishing gear and the fact that the gear could be more diverse and durable. These findings provide a critical scientific basis for assessing the fishing sector's vulnerability to climate change and informing future collaborative decision-making in managing small-scale fisheries in the Colombian South Pacific Ocean.
