El cambio climático, la variabilidad oceanográfica y las pesquerías artesanales del Atlántico Sudoccidental

The project examines how ocean currents, wind patterns, and river runoff influence pink shrimp (Farfantepenaeus paulensis) harvests in Brazil's Patos Lagoon. It highlights that environmental risks are exacerbated by rigid policies, such as fixed fishing seasons and easy credit leading to fleet overcapacity. The research aims to improve fisheries management and catch prediction models by understanding the interaction between social vulnerability and environmental processes.

• Pink shrimp harvests in the Patos Lagoon are driven by ocean currents and wind; specifically, southwesterly winds and low river runoff facilitate the landward movement of larvae into the lagoon, while high river outflows block this influx and reduce catches. El Niño (ENSO) further influences these trends by shifting the distribution of migratory species.
• The negative effects of environmental variability are intensified by inadequate policies, including fixed fishing seasons and easy access to credit, which has resulted in unsustainable fleet expansion and overcapacity.
