This in-depth report, "Aquaculture Development and Global Carbon Budgets: Emissions, Sequestration and Management Options", examines a suite of diverse mechanisms to promote a reduction in carbon emissions and enhancement of carbon sinks associated with marine and freshwater aquaculture of fish and shell fish.
This in-depth report, "Aquaculture Development and Global Carbon Budgets: Emissions, Sequestration and Management Options", examines a suite of diverse mechanisms to promote a reduction in carbon emissions and enhancement of carbon sinks associated with marine and freshwater aquaculture of fish and shell fish.
Farm centred strategies are reviewed, including: reduced energy use and fuel conservation; enhanced production efficiency; direct renewable energy use and electricity generation; biomass crops for on-site substitution; source renewable energy supplies; enhanced soil, water and waste management.
Opportunities to enhance aquaculture associated carbon sequestration in the landscape are considered. Strategies discussed include:
- exploiting organic matter accumulated in aquatic farming systems to build soil organic matter and carbon in marginal or agricultural land;
- enhancing in situ primary production and cultivation of green manure and fodder crops to enhance productivity and sequester carbon;
- increased tree cover and integration of biomass crops on farms;
- wetland restoration;
- horizontal integration;
- extractive aquaculture in freshwater and marine settings.
