A glimpse of the future: impact models for agriculture
Climate impact models are well validated and tested for different sectors, including agriculture, and they provide initial evidence on how humans change the climate system and which risks evolve from that. For agriculture, they are process-based computer models that primarily simulate the biological consequences of a changing climate and can be coupled with global climate models and economic and land use models. They simulate plant growth, phenology and development and the carbon and water balance.
One key input apart from climate data are crop, soil and water management to mimic the strategies that farmers use on their fields as best as possible, for example irrigation, fertilizer use and crop and cultivar choice. With a spatial resolution of half a degree latitude/longitude and global extent this is a challenging task but necessary to consider adaptation. We aim at improving such global management datasets for example to represent tropical and subtropical cropping systems in a more accurate way.
