Climate adaptation in vegetable production
Changes in rainfall amounts and intensity will have a particularly significant impact on annual crops.
More rain brings challenges
Extreme rainfall will increase the risk of nutrient loss through runoff and erosion, especially for vegetables and potatoes where much soil is exposed during the season (Molteberg and Vågen 2016). Increased rainfall in the fall will also make harvesting more difficult, leading to an increased risk of soil compaction, trampling damage, poorer soil quality and soil structure, and it will be more difficult to design harvesting strategies due to more irregular rainfall. Increased rainfall can also lead to extended periods of waterlogged soil, which can cause damage to cereals and vegetables (Seehusen et al. 2016, Molteberg and Vågen 2016).
Wetter conditions during growth and harvest can affect the quality of several crops, especially annuals. Increased pressure from weeds, pests and disease due to increased temperatures could put pressure on plant protection.
Increased temperature and drought
Higher temperatures can increase weed growth and can increase the incidence of diseases and pests. Areas with dry summers can experience drought and crop failure. Spring frosts and the risk of frost on bare soil make planning and start-up in the spring difficult. Flooding and flood damage, landslides, landslides and runoff are also current problems for annual crops. Here too, there are issues related to drainage and hydrotechnical systems.
