Deltas are complex and are among the most vulnerable landforms under climate change. Studying them collectively highlights common stressors that drive their most significant challenges. A holistic conceptual framing of a delta and its feeding river basin is fundamental to effective adaptation planning.

Acknowledgements

Various concepts in this Comment were inspired by the work done in the Rise and Fall project (funded by the Dutch Research Council) in the context of the Vietnamese Mekong Delta, led by P. Hoekstra of Utrecht University, Utrecht, the Netherlands. P. Hoekstra retired this year, and we would like to acknowledge his lifetime contribution to understanding complex fluvial–coastal systems, reflected in many of the ideas presented here. We would like to acknowledge D. Janse’s inspiring art work and contribution to infographics in this Comment. Furthermore, A. van Dijk (Studio A) helped to conceptualize the framework visualization. This work was partially funded by the strategic research budget of Deltares, Delft, the Netherlands.
