In the world of Towers, the decline of liberal internationalism and Western dominance drives governments and civil society to turn to their respective regions in search of identity, partnership and support. This leads to increasingly assertive (sub)regional blocs that gain in strength and relevance. Faced with an intensifying climate emergency, governments, civil society and communities seek to address urgent challenges through effective intra-regional cooperation. This leads to progress on climate change, trade and sometimes conflict management. The extent, nature and manifestation of regionalism varies across regions, including the space afforded to civil society. Powerful regional actors tend to dominate the agenda and inter-regional competition increases, while global governance forums have lost legitimacy in resolving tensions. Robust international civil society networks are also absent, given a changed development landscape.
