This month, I will be researching aquaculture, the practice of cultivation aquatic organisms for commercial recreational or research purposes. The article, Towards a Low-Carbon Footprint: Current Status and Prospects for Aquaculture, reviews the potential to lower CO2 emissions by aquaculture and the reduction of Greenhouse Gas (GHG) emissions in aquaculture.
- There is significant variability in environmental impacts across species and farming methods, emphasizing the need for improved feed efficiency, farming systems, and shifts to species with lower carbon footprints.
- Life Cycle Assessment (LCA) data play a critical role in driving sustainable practices by providing policymakers and industries with insights into the carbon footprint of aquaculture species and systems.
-
Reliable carbon footprint data for aquaculture is difficult to obtain due to diverse production systems, species differences, and uncertainties in LCA modeling, particularly with spatial and temporal variations.
-
Current reviews focus on global warming potential but often overlook other environmental concerns like land use, eutrophication, and post-farm emissions from transportation and processing.
-
To enhance sustainability, future studies should adopt a holistic approach, incorporating additional environmental factors and exploring pathways for carbon sequestration (e.g., pond sediments) while ensuring the production of high-quality food.
Thank you for tuning in and come back next month for a new post!
