The Influence of Climate on Agricultural Decisions for Three European Crops: A Systematic Review

To identify decision areas which could be supported/enhanced by climate services across similar climatic conditions, we identified locations situated at very similar latitudes to the ones in the reviewed studies and prone to similar expected impacts of climate change

Scholarcy highlights

  • The impacts of climate change on the agricultural sector are intrinsically complex due to physical aspects, and socio-economic factors
  • The aim of this paper is to review and identify the main decisions linked to key climate change impacts on the cropping systems of interest—olive, grape and durum wheat—in order to inform the development of climate services and other decision-support tools for these crops in the future
  • The overall limited number of retained studies can be understood as room for more research linking expected climate change impacts and key agricultural-related decisions for the olive, grape, and durum wheat cropping systems
  • For the olive cropping systems located in the southern areas/lower latitudes, the uneven increase in temperature affects the decisions addressing the water stress, altered development and phenology, yield, cultivation areas, variable incidence of pests and diseases, and occurrence of extreme events
  • The most common decisions are likely to be affected by an increase in temperature above the maximum supported by the three crops, or in combination with other climate changes. These decisions mainly relate to irrigation and other water stress reducing measures, choice of varieties, clones and rootstocks, training system and vine load, canopy management, change in planting/sowing and harvest date, pest and disease management, allocation/choice of cultivation area, use of decision support tools, and crop insurance
  • This paper does not provide an exhaustive analysis, the entry points identified can be considered as a starting point for informing the development of climate services which can further support the adjustment of decision making for the olive, grape, and durum wheat cropping systems in the study locations, as well as for similar decision-making contexts beyond those identified in this study
  • For the durum wheat cropping system, the identified impacts did not follow distinct regional trends and were related to reduced suitability of cultivation areas, impaired plant development and phenology, and yield variability
