How can people and lions sustainably coexist?

Linde Desmaele explores the role of US theatre nuclear weapons stationed in Europe. Moving beyond the deterrence vs. reassurance debate

In this opinion article published in World Development, the authors present five research and policy priorities. While it is clear that ‘pluriversal’ designs need to guide the way forward (Kothari et al 2019), defining a set of key pillars can provide direction and purpose across this pluriversality.…

In this article, Thijs van Dooremalen and Philip Smith investigate how public discourse of heatwaves have shifted in British newspaper discourse, drawing on Raymond Williams’s theory of dominant, emergent, and residual cultural patterns to analyse changes in language and interpretation over recent d…
