Stopping Climate Change and Species Extinction simultaneously through Nature-based Solutions - An Analysis of the Biotope Network in Baden-Württemberg

Nature-based solutions are a topic of increasing attention worldwide, as they are proposed to gener-ate environmental, social, and economic benefits simultaneously. However, its actual capabilities have not yet been fully explored, as the idea of this policy instrument is still relatively new. Using the biotope network in Baden-Württemberg as a case study, this paper aims to determine whether nature-based solutions are effective. For this purpose, the thesis focuses on the following research question: "To what extent does the Biotope Network in Baden-Württemberg generate environmental, social, and economic impacts?" Findings derived from expert interviews and analysed documents suggest the successful functioning of the biotope network as a nature-based solution. The network provides environmental services such as CO2 storage and biodiversity protection. By linking habi-tats, the biotope network creates a near-natural and resilient landscape that increases the recreational value for people. It also contributes to the quality of life and thus improves people' health. In addi-tion, the network has an impact on the economy by creating new jobs through its expansion. In the long term, the biotope network maintains essential ecosystem services by preserving the water stor-age capacity of ecosystems and increasing pollination services. It was observed that the network primarily provides environmental benefits but further positively influences the economy. The biotope network has relatively lower social values compared to those mentioned before.
