Presentation on FAO's integrated climate change impact assessment tool called MOSAICC (Modelling System for Agricultural Impacts of Climate Change). Info: MOSAICC@fao.org

1. MOSAICC:
An inter-disciplinary system of models
to evaluate the impact of climate
change on agriculture
FAO NRC
Environmental Sustainability and Climate Change
Adaptation Team (2013)

2. MOSAICC
Modelling System for Agricultural Impacts of
Climate Change
 4 disciplines (climate, hydrology, crops,
economics)
 1 database
 1 server
 1 set of interfaces

3. MOSAICC
The aim of MOSAICC is to assess the impacts of
climate change on agriculture through
simulations
- Based on GCM outputs
- Combining inter-disciplinary models
- Used in a spatially explicit way
- In a perspective of decision support at
national level (Capacity development)

5. Models
• Data Access and Downscaling (DAD) Portal:
statistical downscaling portal for climate scenarios
from ENSEMBLES
• AQUACROP: FAO water-driven crop yield model
• WABAL: FAO crop specific water balance model
• STREAM: DEM-based precipitation-runoff model
• CGE: Computable General Equilibrium model
• Other utilities: interpolation, potential
evapotranspiration, cropping season, etc.

6. Advantages
• Participatory approach
• Remote access
• Nothing to install (web browser)
• Easy data exchange
• Low computing time
• No data format or unit conversion
• Data tracking down the flow

7. Advantages
• Replicability/ study comparison
• Modularity and substitution
• Maintenance needed but no licensing cost
MOSAICC v1.0 to be released beginning of 2014.
