MAGNET is a general equilibrium model of the world economy based on the Global Trade Analysis Project (GTAP) model, focusing on the agricultural sector and the associated land use.
The model counts such options by production and consumption of proteins in order to greenhouse gas emissions and loss of biodiversity. Meat, dairy, arable and horticulture are present in the model, but fish is forced outside the analysis. Especially the indirect use of land to feed the fish in aquaculture has great influence on land use. Clients see it as a major shortcoming that fish remains out of the analysis remains.
The goal of this project is to view the quality in how the fisheries sector in the GTAP database is included and explore ways to split this sector into fisheries and aquaculture.
The outcome is that fishing is a part of food consumption, and therefore belongs in a general equilibrium model that is used for the analysis of changes in dietary patterns.
