Perceptions of energy crop production are assessed in this paper. The Görlitz district (Germany) serves as a case study area for this purpose. Semi-structured interviews with farmers and standardized surveys among lay persons were conducted. Many farmers perceive themselves being responsible for providing many ecosystem services. Farmers prefer a regional scale of energy crop cultivation based on conventional crops. Improved legal frameworks and incentives would safeguard equal competition and ecosystem services. Laypersons think that drinking water, food production, biodiversity and pollination are the most important ecosystem services of agricultural landscapes. Providing biomass for renewable energy production is not considered to be an important ecosystem service. Laypersons believe that biomass production should be restricted to fields that are not needed for food production, and the use of residues or landscape management materials. According to laypersons, more money should be spent to halt the decline of ecosystem services. ; V tomto článku je hodnoceno vnímání produkce energetických plodin. Jako případová studie slouží okres Görlitz v Německu. Byly uskutečněny semi-strukturované rozhovory se zemědělci a standardizovaná dotazníková šetření s laickou veřejností. Většina farmářů vnímá sama sebe jako poskytovatele mnoha ekosystémových služeb. Farmáři preferují pěstování konvenčních energetických plodin s podporou na regionální úrovni. Lepší legislativní nástroje a dotace by podle nich zajistily rovnou soutěž a ekosystémové služby. Laická veřejnost se domnívá, že pitná voda, produkce potravin, biodiverzita a opylení představují nejdůležitější ekosystémové služby, které poskytuje zemědělská krajina. Zajištění biomasy pro produkci obnovitelné energie není považováno za důležitou ekosystémovou službu. Laická veřejnost má za to, že produkce biomasy by měla být omezena na plochy, které nejsou potřebné pro produkci potravin, využití zbytkových produktů či management krajiny. Více peněz by naopak mělo být věnováno proti úpadku ekosystémových služeb.

Ensuring a crisis-proof food supply has become a key political issue. In Germany, official spatial planning allows the use of priority and reserved areas to secure land for agricultural use and regional food supply. The focus should be particularly on climate-resilient areas that also have a stable yield potential in the future. This paper supplements widely used, static approaches for determining priority and reserved areas with a dynamic bio-economic analysis that takes future climate scenarios into account. The results for the German federal state of Brandenburg show a high area equivalence between the static and dynamic approaches. In the case of data gaps, for example, static approaches such as soil quality indices can serve as an adequate proxy for future yield potentials. However, not all climate-robust areas can be classified as potential reserved or priority areas. Furthermore, areas that show low yield potential under future conditions are not released for other land uses. Feedback from stakeholders involved in the study showed that the use of the dynamic approach and a target value using the results of a foodshed model lead to broad acceptance. The method developed here can make a valuable contribution to climate change adaptation in spatial planning instruments.
