This guide is designed to help transportation practitioners understand how and where nature-based and hybrid solutions can be used to improve the resilience of coastal roads and bridges. It summarizes the potential flood-reduction benefits and co-benefits of these strategies, then follows the steps in the project delivery process, providing guidance on considering nature-based solutions in the planning process, conducting site assessments, key engineering and ecological design considerations, permitting approaches, construction considerations, and monitoring and maintenance strategies. The guide also includes appendices with site characterization tools, decision support for selecting nature-based solutions, suggested performance metrics, and links to additional tools and resources.
Climate change impacts ecosystems in many ways, from effects on species to phenology to wildfire dynamics. Assessing the potential vulnerability of ecosystems to future changes in climate is an important first step in prioritizing and planning for conservation. Although assessments of climate change vulnerability commonly are done for species, fewer have been done for ecosystems. To aid regional conservation planning efforts, this report assesses climate change vulnerability for ecosystems in the Southeastern United States and Caribbean.
Historically, studies about climate hazards and social vulnerability have been conducted in separate silos. The Social Vulnerability Index (SoVI) is the first study of its kind to examine both the potential impact of natural hazards and which populations are most likely to be negatively affected. This research, commissioned by Oxfam America, includes a series of layered maps that depict social and climate change-related hazard vulnerability. The maps assist in identifying hotspots in the U.S. Southeast, which are at significant risk in the face of four particular climate change-related hazards: drought, flooding, hurricane force winds, and sea level rise. The specific region of focus is the 13-state region of the US Southeast: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia. Roughly 80 percent of all U.S. counties that experience persistent poverty (defined as a county in which at least 20 percent of the population experiences poverty for three decades or more) lie in this region.
A collection of case studies and information about how coastal communities can plan for and adapt to climate change. These resources represent a national guide for how coastal communities can plan and adapt. Case study issues range from coastal managers addressing sea level rise in Rhode Island to coral bleaching caused by rising sea temperatures in Florida.
