"Despite aquaculture’s contributions to global food security, one of the current concerns is the industry’s greenhouse gas emissions (or GHG emissions), which arise along its supply chains. The expansion of aquaculture may be a potential solution to increased food and nutrition security, but how can it be done in a sustainable and carbon-efficient manner that fits planetary boundaries?


As the world moves toward a decarbonized future to mitigate the long-term effects of climate change, there is increased pressure to ensure that seafood production and supply chains retain environmentally friendly policies and practices. It’s led the aquaculture industry to find innovative carbon mitigation strategies to help cut its GHG emissions, including a focus on aquafeeds. "

Mapping global declines in human-driven mangrove forest loss

"Mangrove forests are globally recognized as highly carbon-rich tropical ecosystems that provide a range of critical economic and ecological services to surrounding coastal populations. However, mangroves have been heavily impacted by degradation and deforestation, with 20 to 35 percent of global mangrove loss over the last 50 years.


Twentieth-century mangrove losses were largely dominated by forest clearing and exploitation for timber production and raw materials, as well as rapid coastal population growth and urban expansion. Economic and political emphasis on aquaculture development has led to large-scale conversion of mangroves to shrimp and rice aquaculture ponds to take advantage of the growth in global aquaculture demand.

Climate change and oceanic warming are expected to increase global sea levels, wave energy and the intensity and frequency of extreme weather events (EWE) such as droughts and tropical cyclones, exacerbating these large-scale losses from land-use change. Measuring the impacts of humans and natural processes on these ecosystems will be critical to the advancement of “blue carbon” science and policy."
