Welfare and poverty impacts of aquaculture growth por Rashid, Shahidur, Minot, Nicholas, Lemma, Solomon

“…The underlying implications of this trend are considered to be so significant that they are now commonly termed a “Blue Revolution,” and there are good reasons for using the term. Aquaculture holds the promise of meeting most of the world’s fish demand without ruining the environment (Economist 2003; Sachs 2007); aquaculture also will be able to help reduce poverty while improving food security and nutritional well-being.1 If aquaculture had stopped growing in 1980—that is, if growth in the world’s fish supply depended only on marine and inland capture fisheries—per capita annual fish availability in 2013 would have been only 14.0 kilograms, which is 17 percent lower than the availability in 1980 and about half of the actual availability of 26.8 kilograms in 2013. …”
