The loss of biological diversity has accelerated at an alarming rate in recent decades. In particular, insect decline has been in the public spotlight since the publication of the Krefeld Study in 2017, which documented a loss of approximately three-quarters of flying insect biomass over three decades. Other studies reveal similar declines across all taxonomic groups. This mass extinction no longer affects only rare species and exotic wildlife but also previously widespread species—a phenomenon referred to as defaunation. Another key finding of the Krefeld Study is that even protected areas could not halt these losses, as most of the study sites were already designated as nature reserves. This indicates that isolated and fragmented conservation measures alone cannot stop the loss of biodiversity; broader systemic changes are required.

The biodiversity crisis has severe consequences for the functionality and stability of ecosystems and is increasingly referred to as the "twin" of the climate crisis. These two ecological crises can no longer be considered separately. Climate change will further accelerate species extinction, while intact ecosystems are more resilient to climatic changes. As stated in the 2019 report by the International Panel for Biodiversity and Ecosystem Services (IPBES): "The diversity of nature maintains humanity’s ability to choose alternatives in the face of an uncertain future." This is especially true for habitats in the most densely human-populated areas: urban ecosystems.

Preserving and promoting biodiversity is an integral part of sustainable urban development in line with the Sustainable Development Goals (SDGs). The loss of suitable habitats poses a significant challenge for many species, and urban environments must play a crucial compensatory role. Natural habitats are increasingly pushed back by human activities, including land sealing, various forms of pollution, and excessive landscaping and maintenance. These are among the primary drivers of habitat loss in cities. This is where the initiative comes in—the Blooming Campus is our contribution to harmonizing human coexistence with functional ecosystems.
