Planetary Boundaries, Polycrisis and Politics in the Anthropocene: Climate Pathways, Tipping Cascades and Transition to Sustainable Peace in Integrative Geography

This chapter explores the impacts of the “great acceleration” in human development and its impact on planetary boundaries and the polycrisis in the Anthropocene. Using an Integrative Geography perspective, it links human-nature relationships, growth limits, and global expansion to crises and geopolitical conflicts, highlighting interconnected risks. The chapter calls for sustainable peace by balancing human […]

We live in times of multiple entwined crises – but our policy responses aren’t keeping up

The authors discuss the inadequacy of current policies in addressing interconnected crises like biodiversity loss, climate change, and pollution. Drawing on two IPBES assessment reports, they argue that while these reports offer effective policy options for transformative change, progress in implementing these solutions remains insufficient.

Understanding biodiversity – ecosystem service linkages in real landscapes

The article examines the impact of human-driven biodiversity loss and its consequences for ecosystem functions and services, emphasizing its role in the global polycrisis. It highlights the need for large-scale, real-world studies to understand biodiversity-ecosystem service linkages beyond small-scale experiments. In response to these research needs, the authors introduce a Topical Collection comprising 13 studies
