Nature-based solutions have several potential advantages over gray (engineered, human-made) infrastructure, including: co-benefits not present with gray infrastructure, such as provisioning habitat, increasing biodiversity, and having aesthetic qualities. If constructed appropriately, nature-based solutions have the capacity to be self-regulating and respond and adjust to change, (e.g., a vegetative community whose members can shift in relative dominance over time in response to changing weather conditions; marsh vegetation that can trap sediment and build upon itself, adding capacity for resilience to sea level rise).
