Among climate-change related effects, drought, heat, and waterlogging are the most important adversely affecting the production of potatoes in Europe. As climate change progresses, agricultural practices must adapt to maintain potato yields. This study is based on a European-wide survey. It presents potato growers’ perception of climate change, its impact, and possible adaptation strategies, focusing on the results from Germany, Switzerland, and Austria. Potato growers strongly agreed that climate change had affected their potato production in the last ten years, as indicated by 98% of German and more than 90% of Swiss and Austrian respondents. Drought caused the most severe impact, and to varying extents damage was caused by heat and the occurrence of pests and pathogens. The most preferred adaptation measure was the planting of adapted varieties. In line with the comparably low access to at least partial irrigation that Austrian potato growers reported, Austria appeared to be the country most affected by drought. Other more pronounced challenges were late spring frost, flash floods, and soil erosion. The study highlights and discusses specific differences between the countries, as well as between conventional and organic potato production based on the Austrian responses. The results underline that to successfully develop effective climate change mitigation strategies, country-specific and local challenges and needs should be considered.
