Nature has been running resilience experiments for billions of years. Ecosystems do not predict the next storm, the next drought, or the next temperature spike. They survive, and often thrive, because they build in diversity, adaptability, and robustness as operating principles. The proposal to adopt diverse, adaptive, and robust engineering (DARE) is not a retreat from science. It is a more honest application of it. By shifting focus from predicting uncertain inputs, like exact wave heights decades from now, to managing acceptable outputs, such as tolerable flood levels on shore, DARE offers a practical toolkit for infrastructure that works even when forecasts fail.
That shift in perspective matters because the climate is moving beyond our historical baselines faster than models can be recalibrated. We see this tension across our coverage. In our report on The ICJ anchors ocean law into the climate governance framework, the legal system is trying to catch up with a reality that keeps changing the rules. DARE flips the problem: instead of asking courts or forecasts to resolve uncertainty, it designs physical systems that can absorb it. Similarly, our work on Understanding drives protection: microscale environments reveal new pathways for coral reef restoration shows how restoration ecologists are learning from natural microhabitats rather than imposing rigid designs. DARE applies the same lesson at the scale of coastal engineering.
What does this mean in practice for hydraulic engineers, planners, and policymakers? First, it reframes the question from "what will the future look like?" to "what range of outcomes can our infrastructure tolerate?" That is a measurable, actionable target. For coastal flooding, DARE might mean designing breakwaters that function across a wider spectrum of wave conditions rather than optimizing for a single projected storm. For estuarine salt intrusion, it could involve building adaptive barriers that shift with seasonal variability rather than permanent structures locked to a static forecast. The goal is not to eliminate uncertainty, that is impossible, but to engineer systems that degrade gracefully rather than fail catastrophically when conditions exceed expectations.
The most compelling aspect of DARE is its humility. It acknowledges that prediction is a useful tool, not a reliable foundation. A concrete point to watch is how this philosophy translates into procurement and regulation. Current infrastructure contracts typically specify fixed design criteria based on modeled extremes. DARE would require performance-based standards that test resilience across multiple plausible futures, not just the most probable one. That is a bureaucratic shift, but it is the kind of change that turns an elegant ecological principle into a real-world defense against rising seas and shifting coastlines.
