APES, a modular model was developed in the SEAMLESS project (Van Ittersum et al., 2008)to assess, in different EU regions, the impact of farm management on crop production andenvironmental externalities. Such purpose assumes the capability of APES to simulatecropping systems in a wide range of climate, soil and crop management. The main topic ofthis study is to evaluate APES, under different stresses and management practices(temperature, water and nitrogen), to simulate crop production and nitrogen and waterdynamics. For this evaluation, APES was compared to the CropSyst (Stöckle et al., 2003)model (widely evaluated and used under different biophysical conditions and managementpractices). An explicit description of the limitations and specificities of each modellingapproach is related to the behaviour of each model in different situations.

This paper presents the main results obtained from the study of hydrological processes in the Vallcebre Research Catchments since 1988. Distributed hydrometric measurements, environmental tracers and hydrological modelling were used to understand Mediterranean catchment behaviour and to provide new data to help assess the global change effects on these catchments' water resources. Thirty years of hydrological processes observation in the Vallcebre Research Catchments have increased understanding not only of their hydrological response, but also of the main hydrological and erosion processes characteristic of Mediterranean mountain catchments. This paper briefly summarises the main results obtained since 1988 on ecohydrological processes, hydrological response, runoff generation processes, erosion and sediment transport. Some of the main findings from this research are (i) the importance of temporal variability in precipitation to determine the hydrological processes; (ii) the paramount role played by forest cover in reducing soil water content; (iii) the marked influence of antecedent wetness conditions on runoff generation that determine different runoff responses; (v) the dominant contribution of pre-existing water during floods; (vi) the importance of freezing-thawing processes in badland areas on erosion and the role of summer convective storms in controlling sediment transport. © Universidad de La Rioja. ; The 30 years of research in the Vallcebre catchments have been carried out with the support of various research projects funded by the Spanish government and the European Community. Among these are the two current projects: TransHyMed (CGL2016-75957-R AEI/FEDER, UE) and MASCC-DYNAMITE (PCIN-2017-061/AEI). Research into the Vallcebre catchments also received funding from the convention between the CSIC and the MAPAMA (RESEL). C. Cayuela is beneficiary of a pre-doctoral FPI grant (BES-2014-070609), A. Molina and M. Moreno de las Heras are beneficiaries of contracts within the "Juan de la Cierva" program (FJCI-2015-24597 and IJCL-2015-26463, respectively), funded by the Spanish Ministry of Economy, Industry and Competitiveness, and G. Bertran is beneficiary of a contract within the program "Sistema Nacional de Garantía Juvenil" (CS2_CAT_ IDAEA_049).

This 26th dossier d'Agropolis is devoted to research and partnerships in agroecology. The French Commission for International Agricultural Research (CRAI) and Agropolis International, on behalf of CIRAD, INRAE and IRD and in partnership with CGIAR, has produced this new issue in the 'Les dossiers d'Agropolis international' series devoted to agroecology. This publication has been produced within the framework of the Action Plan signed by CGIAR and the French government on February 4th 2021 to strengthen French collaboration with CGIAR, where agroecology is highlighted as one of the three key priorities (alongside climate change, nutrition and food systems).
