The potential impact of climate change on fisheries and aquaculture in the Asian region
Asia is currently home to 87 percent of all people involved globally in fisheries and aquaculture. The sector contributes significantly to the national gross domestic product of many countries in the region and plays a significant role in food security. Between 15 to 54 percent of the annual protein intake in the region comes from fisheries and aquaculture products. The effects of climate change, such as increasing ocean acidification, shifting food distributions and more frequent cyclones, may increase the negative impacts on capture fisheries already suffering from overexploitation, coastal degradation and pollution. The productivity and viability of aquaculture operations may also suffer negatively from higher sea water levels, flooding, increased competition for water resources and disease occurrence patters. The impacts are likely to be far from uniform and it is expected that the region will face very specific and locally variable challenges. This publication provides insight int o the current state of knowledge about the impacts of climate change in Asia and examines the implications for the fisheries sector. A review of the significance of the findings for policy-makers in the region is provided as well as steps that can be taken to minimize the negative impacts and capitalize on potential opportunities.
