What is the outlook for fish in a globalizing food economy, and how will trends in the fish sector affect the poor and the environment during the next two decades? A new book from IFPRI and the WorldFish Center, Fish to 2020: Supply and Demand in Changing Global Markets, and an accompanying food policy report, Outlook for Fish to 2020: Meeting Global Demand, examine changes in the fish sector; the forces driving these changes; and the implications of the changes for fish consumption, production, prices, trade, the environment, and the world’s poor.
