A draft of the first three background chapters of a working paper that compares the Blue Economy in Seychelles, Saint Lucia, and The Bahamas using Satellite Accounts. The research is led by the United Nations Economic Commission for Africa (UNECA, with support from the Caribbean Development Bank (CDB). This preview has been developed for discussion during UNECA's 24th Intergovernmental Committee of Senior Officials and Experts (ICSOE) in Eastern Africa being held in November 2020. These chapters: (1) summarize the discussions of the previous papers by UNECA and CDB, including defining the Blue Economy and explaining the methodology and (2) provide stylized facts about the Seychellois, Saint Lucian, and Bahamian economies, highlighting trends in key Blue Economy industries.
