ADAPTATION RESPONSES
Systematic observations and ongoing analysis of changing climatic conditions in various production areas, and where possible in specific microclimates in an area Long-term cultivar and sport evaluations across different climatic regions, with development of a database for ongoing statistics and…
KEY POSITIVE CHANGES
Increasing Growing Degree Hours during flowering and fruit set Reduction in cold hours during pollination and fertilization Reduction in frost risk (although even a small remaining risk can be devastating) Variability of daily maximum and minimum temperatures not likely to…
KEY INCREASES IN RISKS
Loss of chilling, with greater impacts in warm and mid-cool areas (lower impacts in the coldest areas). Late-autumn heat. Desiccating weather (heat, wind, low RH) during flowering with implications for early, mid and late flowering cultivars, especially in the Breede,…
