    This paper assesses the local economic impact of pelagic Sargassum seaweed washed ashore in tourism-heavy coastal zones in the Mexican State of Quintana Roo. The study relies on a carefully designed geographic information systems (GIS) dataset of monthly observations from 2016 to 2019 for 157 beach segments. The dataset comprises an innovate measure of Sargassum seaweed presence, remotely sensed nighttime light intensity as a proxy of economic growth, as well as information on key infrastructure, sociodemographic and beach characteristics. We apply a fixed-effects regression model that controls for general time trends and unobserved, time-invariant differences across observations. We estimate that the presence of Sargassum in a beach segment reduces nighttime light intensity by 17.5%, representing an approximate 11.6% decrease in gross local product. Considering that impacts of Sargassum on local economic activity may be delayed due to reputational effects, our analysis finds that significant lagged effects can be detected up until 12 months after Sargassum was detected on the shoreline. These effect sizes range between a 5.9 and a 9.9% reduction in gross local product. Various robustness checks, including an adjusted measurement of Sargassum and the consideration of potential spatial correlation across beach segments, indicate that estimated impacts are consistently significant and negative across numerous specifications. For one of most tourism-dependent regions in the world, the recurrent influx is one of the most threatening manifestations of climate change. Our research is the first to robustly quantify the economic impact of Sargassum, and highlights the extent to which economic activity is negatively affected by the accumulation of seaweed and how these effects persist over time. The next important step is for both public and private sectors to invest in forecasting systems and containment strategies as well as engage in cleanup efforts to mitigate severe accumulations, inducing economic resilience in coastal communities.

    We present two case studies in which coastal vulnerability modeling was used to quantify the role those coastal ecosystems play in reducing risk to coastal communities now and with future sealevel rise. These analyses were used to inform post-disaster reconstruction and coastal resilience building efforts as well as climate change adaptation strategies. Our goal is to quantify the role that coastal habitat plays in reducing risk to people and shoreline under current conditions and with future sea level rise (SLR). With SLR, we find that the extent of shoreline most exposed to coastal hazards would more than double, and the total population would nearly triple in The Bahamas. Similarly, the population living along high-risk shorelines increases by over 10x if habitat is lost and sea level rise is accounted for in the Mesoamerican Reef.

    This chapter describes tools and a methodology to model wind and flood risks from tropical storms under present and future climate accounting for natural infrastructure. Wind forcing provide a crucial link to hydrodynamic models that can be used in risk assessments to estimate extent of and damages from flooding and erosion. Further, such flood risk models can then include the effects of ecosystems, such as mangroves, to model the effects on risk of conservation and restoration outcomes but also individual nature-based projects to reduce risks. The chapter describes hazard modeling techniques and presents simple applications to (1) assess the effect of climate change in the Caribbean, by estimating wind fields for tropical cyclones for present and future climate scenarios, (2) address the limited observations in hurricane data by using existing tools to derive synthetic storms and readily use them in coastal models, and (3) compare modeling approaches and datasetsto provide recommendations for assessing flood attenuation of mangroves. The results and data developed in these applications is available with this chapter to be used in other local applications, or to infer damages from wind or in flood hazard models.
