Biodiversity policy integration in five policy sectors in Germany: How can we transform governance to make implementation work?

Drivers for biodiversity loss are largely regulated by policies in non-environmental sectors. The limited mainstreaming of biodiversity into respective policies remains yet to be analysed. During the process of updating the German National Biodiversity Strategy, we conducted 33 interviews and a stakeholder workshop to analyse barriers and levers for biodiversity integration in five policy sectors: agriculture, forests, marine & coastal areas, business & industries, rural & urban development. Based on Biodiversity Policy Integration literature, we distinguish four leverage points for transformation related to inclusive, integrated, accountable and adaptive governance. We found that biodiversity inclusive narratives and innovative approaches exist but are overshadowed by conflicting vested interests. Dominant sector policies are incoherent and continue to provide harmful subsidies. Institutional structures fail to reflexively respond to ambitious agendas and are locked into sector specific accountability hierarchies. Thus, transformative national planning needs to overcome institutional lock-ins and empower agents to develop innovative solutions.
