This document summarizes a presentation given by Ulrich Kleinwechter on the GLOBIOM model for long-term global agricultural and forestry sector outlook. GLOBIOM is a global partial equilibrium model that integrates agricultural and forest markets with biophysical crop, livestock, and forest models. IIASA has used GLOBIOM to conduct various foresight activities exploring the effects of socioeconomic drivers and climate change on agricultural production, trade, prices, land use and food availability through 2050 and 2100. The results show positive outlooks for food availability but increased emissions without mitigation efforts, and that socioeconomic factors have a greater influence on outcomes than climate impacts alone.

 Global scale agriculture and forest sector model based on detailed
spatial resolution (>200k cells)
 Partial equilibrium
 Agricultural, wood and bioenergy markets
 30 world regions
 Bilateral trade
 Bottom-up approach
 Explicit description of production technologies a la Leontief
 Technologies specified by production system and grid cell
 Main data source
 FAOSTAT, complemented with bottom-up sectoral models for
production parameters
 Base year: 2000
 Time step: 10 years, time horizon: 2030/2050 but also 2100

22. 22
 Generally positive outlook for food availability by 2050 under SSP 2
 Albeit at cost of LUC and high emissions, if unabated
 Contingency of agricultural development on SSP
 Market effects of climate change mitigation
 Price increases & reductions in calorie availability
 Production effects of climate change mitigation
 Changes in production levels, production system transitions, spatial
reallocation
 Effects of socio-economic development dominate climate change
impacts

23. 23
 GLOBIOM provides integration of agriculture and forest
sectors in a comprehensive framework
 Links with biophysical models (EPIC, RUMINANT, G4M)
 Extensions: GHG emissions accounting, input use (fertilizer,
water), food security
 Possibility for regional zooming-in
 E.g. Congo Basin, Brazil
 Disaggregation of production with high spatial resolution
and along production systems
=> Potential for applications to technology assessment and
priority setting
