In order to evaluate the sustainability issues that we will face in the near future, there is a need to understand the relationships between crop growth, land surface characteristics and energy and water cycles. The land surface model JULES includes the full hydrological cycle and vegetation effects on energy, water and carbon fluxes. However, it only simulates land surface processes in natural ecosystems. A dynamic crop growth structure and some model adaptations have been implemented within JULES: JULES-SUCROS. JULES-SUCROS has been validated against CarboEurope flux data in 3 geographically distinct regions in Europe. With JULES-SUCROS as tool, the effects of crop growth on the land surface have been compared to grass under current and changed atmospheric conditions. JULES-SUCROS improves the simulations of crop growth, energy and water fluxes over Europe, compared to the original land surface model JULES. Simulations with JULES-SUCROS show that land-atmosphere interactions are strongly affected by vegetation type and dynamic. Therefore, including a dynamic crop growth structure, such as JULES-SUCROS, within a GCM is likely to improve weather and climate simulations and so to help to better understand the interactions between crop growth, land and climate systems.
