To fill this gap, we conducted 24 semi-structured interviews in a study site located in the Catalan Pyrenees. Our results show for the first time in an industrialized context that farmers perceive multiple interrelated climate change impacts on local agroecosystems. For instance, snowfall and freeze events have decreased, which respondents associated with the increase of pests and diseases affecting both wild flora and cultivated plants. Similarly, changes in precipitation patterns lead to a perceived decrease in useful rain for agriculture. Farmers are also reporting changes in their management practices, such as increased irrigation or use of pesticides, which respond to these climatic factors but also to changes in the crops that are cultivated. Crop diversity is in decline in the area both at the species and landrace levels, especially in rainfed fields. This is mainly driven by socioeconomic factors such as agricultural abandonment or access to commercial seeds, although climate change factors such as increased pests or decreased rainfall can have an impact. Despite the crop diversity losses found, many landraces have been maintained, mainly due to their cultural value, and also new crop species have been introduced, which are now viable due to the increase in temperature. Although we focused on a specific case study, we found several trends that are also present in other contexts. Therefore, the results of this research are relevant at a global scale since they show that climate change is affecting mountain agroecosystems in industrialized contexts and may affect more drastically both agrobiodiversity and crop management practices in agroecosystems worldwide. http://hdl.handle.net/2072/463327 Adaptation Agricultural industrialization Agrobiodiversity Home gardens Landraces Traditional ecological knowledge Climate change in the Catalan Pyrenees intersects with socioeconomic factors to shape crop diversity and management
