**5. Conclusions**

This modeling study will allow us to better understand if the APEX model could be considered a useful tool for studying agroecosystems in Mediterranean climates. Obtaining good results in the calibration and validation process will allow us to use the APEX model to assess the impact of land managemen<sup>t</sup> and climate change in the Karla watershed.
