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. | 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.

''Remark on Input/Output Table below'': The LPJmL module on crop growth directly interacts with the modules on [[Carbon cycle and natural vegetation|terrestrial carbon]] and [[Water|water cycles]]; 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. | |||

- 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?
Introduction
Property "HasInputVar" (as page type) with input value "CO2 concentration" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
