Plant breeding collects, induces and rearranges genetic diversity followed by selection. Breeding may contribute to diversity in farmers’ fields or significantly reduce it. History has numerous examples of both. The diversity of many crops have gone through domestication, dispersal and modernization bottlenecks. Between these major decreasing processes, diversity has picked up through different evolutionary processes, and plant breeding affected by policies. Major negative effects of plant breeding on diversity have been recorded following the modernization bottleneck, but alternative breeding strategies have come up as well, both in the formal system and in the interphase between formal and farmers’ seed systems. Multiline breeding and participatory plant breeding are introduced as examples to also analyse effects of current developments in technology and policy. This paper intends to shed some light on the questions: how will current developments in technology and policy affect crop genetic diversity? Are we heading for a new bottleneck—either a molecular or a policy bottleneck, or a combination of both? Or could the future become more diverse? We look at the relationship between breeding, policies, and crop genetic diversity in farming systems with a birds-eye view. Notably because of current policy trends we warn for a new diversity bottleneck.

Making a strong case for biodiversity protection is central to meeting the biodiversity targets in international agreements such as the CBD and achieving the UN Sustainable Development Goals. Effective arguments are needed to convince diverse actors that protection is worthwhile, and can play a crucial role in closing the implementation gap between biodiversity policy targets and outcomes. Drawing on a database of arguments from 11 European case studies, along with additional interview and case study material from all 13 case studies of the BESAFE project, we analysed relationships between potential and observed effectiveness of arguments. Our results show that strong logic, robustness, and timing of arguments are necessary but not sufficient conditions for arguments to be effective. We find that use of multiple and diverse arguments can enhance effectiveness by broadening the appeal to wider audiences, especially when arguments are repeated and refined through constructive dialogue. We discuss the role of framing, bundling and tailoring arguments to audiences in increasing effectiveness. Our results provide further support for the current shift towards recognition of value pluralism in biodiversity science and decision-making. We hope our results will help to demonstrate more convincingly the value of biodiversity to stakeholders in decision processes and thus build better cases for its conservation.
