Urban Hydrologics proposes that all Tropical Islands Nations strive to achieve Holistic Resilience. This approach considers the integration of inland and coastal adaptation to achieve high-performing results that stand the test of time. Global surface temperatures will exacerbate the storms and weather impacts on small islands and coastal watersheds. The Urban Hydrologics approach states that Holistic Resilience becomes a priority for planning adaptation solutions for Inland & Coastal communities and that existing hydrological networks begin to employ green infrastructure, coastal SLR/storm surge protection, and water-sensitive urban design elements in coastlines, rivers, corridors, ecological patches, parks, streetscapes, and plot/building scales.
