Book (stand-alone)Technical studyDeep-ocean climate change impacts on habitat, fish and fisheries
FAO Fisheries and Aquaculture Technical Paper No. 638
2019Also available in:
No results found.This publication presents the outcome of a meeting between the FAO/UNEP ABNJ Deep-seas and Biodiversity project and the Deep Ocean Stewardship Initiative. It focuses on the impacts of climatic changes on demersal fisheries, and the interactions of these fisheries with other species and vulnerable marine ecosystems. Regional fisheries management organizations rely on scientific information to develop advice to managers. In recent decades, climate change has been a focus largely as a unidirectional forcing over decadal timescales. However, changes can occur abruptly when critical thresholds are crossed. Moreover, distribution changes are expected as populations shift from existing to new areas. Hence, there is a need for new monitoring programmes to help scientists understand how these changes affect productivity and biodiversity. The principal cause of climate change is rising greenhouse gases and other compounds in the atmosphere that trap heat causing global warming, leading to deoxygenation and acidification in the oceans. Three-dimensional fully coupled earth system models are used to predict the extent of these changes in the deep oceans at 200–2500 m depth. Trends in changes are identified in many variables, including temperature, pH, oxygen and supply of particulate organic carbon (POC). Regional differences are identified, indicating the complexity of the predictions. The response of various fish and invertebrate species to these changes in the physical environment are analysed using hazard and suitability modelling. Predictions are made to changes in distributions of commercial species, though in practice the processes governing population abundance are poorly understood in the deep-sea environment, and predicted -

Also available in:
No results found.FAO’s Blue Hope Project approach seeks to address these challenges by developing sustainable and inclusive multi-sectoral investment plans that facilitate the transition of small-scale fishing communities to blue growth. To this end, the blue growth investment plans are being developed by leveraging and integrating existing FAO tools and international instruments, including the Ecosystem Approach to Fisheries (EAF) provides the foundation for capture fisheries sustainability, the Ecosystem Approach to Aquaculture (EAA) is an approach to develop aquaculture while minimizing environmental degradation, FAO’s value chain methodologies ensure that value chain development potential is assessed in gender-sensitive ways and so on. -
