MOSAICC

FAO-MOSAICC (for MOdelling System for Agricultural Impacts of Climate Change) is a system of models designed to carry out each step of the impact assessment from climate scenarios downscaling to economic impact analysis at national level.

The four main components of the methodology are a statistical downscaling method for processing GCM (Global Circulation Models) output data, a hydrological model for estimating water resources for irrigation, a crop growth model to simulate future crop yields and finally a CGE (Computable General Equilibrium) model to assess the effect of changing yields on national economies.

The modelling system also comprise documentation on methods and tools, as well as user manuals and sample data. The system will be installed in candidate countries and national institutions in which training will be organized (more details in section "Dissemination and capacity building"). In 2011, the system and related capacity building activities will be fully tested in Morocco before being exported to other countries.

FAO-MOSAICC is being developed in the framework of the EC/FAO Programme on “Linking information and decision making to improve food security” (GCP/GLO/243/EC), theme 3 "Climate change and food security". More information on www.foodsec.org.
