LPJmL simulates yields per crop under optimal management intensities for each grid cell and irrigation system as well as irrigation water requirements, which is input to the IMAGE Land-use allocation model (Component [[Land-use allocation]]) for simulations of land-use change dynamics. Climate change calculated by the IMAGE climate model (Component [[Atmospheric composition and climate]]) directly affects future agricultural productivity because these components are dynamically linked in annual time-steps.

Remark on Input/Output Table:
"Remark on Input/Output Table":The LPJmL module on crop growth directly interacts with the modules on terrestrial carbon (Section 6.1), water cycles (Section 6.3); as they are all an integral part of the LPJmL model, sharing the same soil and water balance processes, the distinction in different modules is somewhat artificial.

Key policy issues

  • How will climate change affect the productivity of current and future agricultural areas?
  • How could management improve agricultural productivity under current and future water constraints?
  • How will agriculture affect the Earth system with respect to carbon emissions, freshwater availability and nutrient cycles?
