However, they are often subject to highly controversial societal debates, such as in the case of genetic engineering or certain forms of animal production. This paper provides insight in the extent to which these conflicts are rooted in the conditions and processes of agricultural innovation. We analyze the German agricultural innovation system from an adapted systems perspective and present three case studies. These case studies potentially contribute to solving current challenges and are influenced in their development process by different factors: different technologies, actors, links to other branches, overlapping frame conditions and current challenges as well as societal debates. The innovation system concept applied to different system levels provides insight into interrelationships and hence allows us to identify starting points for improvement. The explanation and potential solution in mastering the high expectations on agricultural innovation and societal debates the authors point to two aspects: 1) As it is in many other areas trust is an important basis for innovative collaboration in small networks. (2) At the same time innovation success depends on the incorporation of societal trends in innovation processes, e. g. via a greater involvement of consumers and retailers at an early stage. Overall, besides the balancing of continuity and openness of agricultural innovation networks, our results raise questions for the (self-)concept and design of the agricultural innovation system, for incentives and shaping of interdisciplinary collaboration as well as for the (self-)role model of the involved actors.

The implementation of eco-innovations can be a strategy to combine economic benefit and reduce negative environmental impact. German greenhouse production is highly energy intensive, as heating and energy account for the second largest cost factor. Thus, the sector wants to develop and implement eco-innovations to speed up the process towards increased sustainability. In this paper, a sectoral systems of innovation (SSI) analysis is presented to identify and describe interrelated systemic barriers for developing and implementing such innovations into the sector. The SSI was used as an analytical framework, which enabled covering different system levels and components in the research in order to draw a comprehensive picture of this specific innovation environment. A mixed-methods, explorative approach was used: a literature analysis, followed by an expert workshop and semi-structured expert interviews, was conducted to understand the barriers for development and implementation of such innovations. A SWOT workshop assisted in generalizing results from selected innovation examples. A complementary two-wave Delphi study was used to identify innovation activity, important actors, policies and drivers within horticulture. Based on these data, we were able to identify different barrier-types, showing how they are interconnected and affect innovation processes increasing ecological modernization of the sector.
