The cultivation of a single crop is common practice in agriculture today, i.e., crops such as wheat or corn are usually grown as pure cultures. However, as monocultures without versatile crop rotation, they are not always environmentally friendly. They use nutrients in a very one-sided way and are more susceptible to pests, which means that fertilisers are not used optimally and pesticides have to be applied regularly. This damages both groundwater and soil, leaving the soil less protected from weather extremes and erosion.

Weather extremes such as heat, drought or heavy rain have been putting pressure on agriculture for a long time and are increasingly causing crop failures. To respond to the challenges of climate change, new strategies are needed for the cultivation of fruit, vegetables and cereals. One promising approach is so-called agri-photovoltaics. Here, arable land is not only used to grow important food crops, but also to generate electricity at the same time. An initial pilot plant at Lake Constance proved to be economically viable after only a short time.
