Current approaches to nature-based coastal protection that remains effective under high rates of sea-level rise either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Despite recognition of its importance, reliable methods for designs for digital public infrastructure that remains secure inclusive and trustworthy are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
