As aquaculture assumes greater significance as a means to meet global food and nutrition demands, concerns about its environmental impacts are on the rise. Modeling key fish supply and aquaculture systems for biophysical resource use is a vital step for estimating environmental footprints and was the focus of a WorldFish study in Myanmar.
A recent paper stating that farmed shrimp has a ‘jumbo’ carbon footprint is an overestimate, say WorldFish and partner researchers, largely because it fails to account for the greatly reduced competition between shrimp farms and mangrove forests as well as an increased recognition of the value of mangroves.
Climate change threatens the productivity of fisheries, and the livelihoods of many dependent communities. Fish producing countries throughout Africa, Asia, and Latin America face challenges from a changing climate, but Africa is especially at risk, with fourteen of the world’s 20 most vulnerable countries found within the continent.
