Understanding and measuring the contribution of aquaculture and fisheries to gross domestic product (GDP)

by Junning Cai, Hui Huang, and PingSun Leung

Published 1 October 2019

This paper proposes models to determine aquaculture and fisheries' contribution to Gross Domestic Product (GDP), given that no internationally agreed methodology is yet available. These include input-output models (with mathematical formulae and numerical examples), as well as alternatives for data-poor environments such as the satellite account approach. This will contribute to reporting on the fisheries GDP measure (Indicator 14.7.1), which is part of the Sustainable Development Goals (SDGs) and 2030 agenda, as well as to establishing a formal methodology, standards and guidelines for measuring aquaculture and fisheries' economic contribution. The publication also looks at how to apply the evidence obtained to policy and planning at the national, regional and global level, and takes note of the numerous practical issues to be resolved. Supply and demand-side factors that affect the contribution notably need to be taken into account. Inclusion of a fisheries GDP measure in the SDGs therefore provides a timely opportunity to move this enterprise forward.

Short-term Projection of Global Fish Demand and Supply Gaps

by Junning Cai and PingSun Leung

Published 5 December 2017

This publication presents a short-term projection model developed to assess and monitor future fish demand and supply gaps at the country level (nearly 200 countries or territories), regional level (about 40 country groups), and global level for nine species groups. Salient results for each level are presented in the main text, with key results for all countries and all nine species groups (including both standard and conservative projections) documented in the appendix.
