Sustainable small-scale fisheries development
Worldwide, small-scale fisheries face significant challenges due to overfishing, which is more severe in developing countries. This study introduces a novel methodology combining bioeconomic and Driver-Pressure-State-Impact and Response models to assess overfishing using Sri Lanka as a case study. It also provides policy recommendations for sustainable fisheries development. The analysis of 32 years of fish catch and effort data reveals a 130% in…
