The FAO modelling system to assess climate change impacts on agriculture at national level
MOSAICC (for MOdelling System for Agricultural Impacts of Climate Change) is a system of models and utilities designed to carry out inter-disciplinary climate change impact assessment on agriculture through simulations.
The main components of the system are one statistical downscaling portal to downscale Global Circulation Models (GCM) data to weather stations networks, one hydrological model for estimating water resources for irrigation in major basins, two water balance-based crop models to simulate crop yields under climate change scenarios and finally one Computable General Equilibrium model (CGE) to assess the effect of changing yields on national economies.
The system also comprises documentation on methods and tools, as well as user manuals and sample data. The system is typically deployed in national institutions (ministries, research institutes, universities etc) and delivered with training sessions, under the framework of an inter-institutional agreement and supported by trust funds (more details in section "Dissemination and capacity building"). While the pilot test is being undertaken in Morocco, the release of the first stable version is expected for the beginning of 2014.
FAO-MOSAICC is developed in the framework of the EU/FAO Programme on “Improved Global Governance for Hunger Reduction”.
