note = {Technological change in agriculture is essential to balancing environmental conservation with global food security. Robotics, artificial intelligence, and digitalization (RAD) in agriculture offer potential for greater sustainability. Given the visibility of such changes in the context of food production, societal resistance is possible – but positive public perceptions could also help build trust. Therefore, this dissertation investigates public acceptance of RAD-based agriculture and contextualizes acceptance with other sustainable farming approaches. Further, this dissertation explores whether integrating solar energy production with agriculture (Agrivoltaics) can enhance the societal acceptance of solar energy projects on agricultural land.
The first two essays examine public attitudes towards crop farming robots in Germany, for which representative online survey data have been collected. Images with concrete examples were presented to the participants. Analysis of the first essay finds low awareness of automated crop farming but positive overall attitudes and high interest. A framing experiment reveals that positive information on environmental benefits improves public perceptions more than positive information about food security or labor impacts. The second essay examines heterogeneity in public acceptance of robotics and autonomous systems. Using cluster analysis, four attitudinal groups were identified, ranging from strong proponents to skeptics. While most participants support the use of robots in crop farming, concerns persist about structural impacts on family farms.
Essay three compares public attitudes toward agrivoltaics and open-space solar in Germany based on another online survey. While both systems reduce landscape attractiveness, agrivoltaics is viewed more favorably. More participants stated a willingness to pay a premium for agrivoltaics electricity, suggesting that it may support socially acceptable energy transitions. The type of agricultural system in which agrivoltaics is integrated appears to have a limited impact on consumer perception.
Essay four examines public acceptance of RAD systems – compared to the other sustainability-oriented systems of organic farming (OF) and genetic engineering (GE). Using experimental survey data and qualitative discussions with German residents, preferences were assessed across three decision levels: willingness to pay (WTP) for products, willingness to invest (WTI) in research, and prioritization of policy goals. Results show that OF is consistently most preferred, while GE is most strongly rejected across all levels. Effects of information treatments on WTP were higher for RAD and GE than for OF, whereas the effects on WTI exhibit the opposite pattern. Although specific information provision increases the overall acceptance of all three approaches, information does not alter the relative ranking of the approaches. The focus group discussions further reveal that the combination of OF and RAD is perceived positively, while skepticism persists in integrating GE in agricultural production.
The dissertation emphasizes the need for strategic communication of RAD innovations to prevent negative narratives and promote acceptance. Actively highlighting benefits – especially environmental benefits – is essential. Communication channels, especially marketing in contexts where economic decisions are made, as well as farmers acting as multipliers, offer promising potential to enhance acceptance. Agrivoltaic systems show public support potential but require targeted subsidies; synergies with societally accepted autonomous farming could improve their economic feasibility.},
