Assessing climate change associated sea‐level rise impacts on sea turtle nesting beaches using drones, photogrammetry and a novel GPS system

Evaluation of observed sea level rise impacts to date has emphasized sea level extremes, such as those from tropical cyclones. Far less is known about the consequences of more frequent high-tide flooding. Empirical analysis of the disruption caused by high-tide floods, also called nuisance or sunny-day floods, is challenging due to the short duration of these floods and their impacts. Through a novel approach, we estimate the effects of high-tide flooding on local economic activity. High-tide flooding already measurably affects local economic activity in Annapolis, Maryland, reducing visits to the historic downtown by 1.7% (95% confidence interval, 1.0 to 2.6%). With 3 and 12 inches of additional sea level rise, high-tide floods would reduce visits by 3.6% (3.2 to 4.0%) and 24% (19 to 28%), respectively. A more comprehensive understanding of the impacts of high-tide flooding can help to guide efficient responses from local adaptations to global mitigation of climate change.

AbstractSea level is expected to rise 44 to 74 cm by the year 2100, which may have critical, previously un-investigated implications for sea turtle nesting habitat on Bioko Island, Equatorial Guinea. This study investigates how nesting habitat will likely be lost and altered with various increases in sea level, using global sea level rise (SLR) predictions from the Intergovernmental Panel on Climate Change. Beach profiling datasets from Bioko’s five southern nesting beaches were used in GIS to create models to estimate habitat loss with predicted increases in sea level by years 2046-2065 and 2081-2100. The models indicate that an average of 62% of Bioko’s current nesting habitat could be lost by 2046-2065 and 87% by the years 2081-2100. Beach D is predicted to be the least vulnerable to increases in sea level. Erosion and tall vegetation berms have been documented on Beaches A and B, causing green turtles to nest uncharacteristically in front of the vegetation line. Development plans are currently underway for Beach D. With Beach D being the least susceptible to future increases in sea level, development and anthropogenic encroachment here would be especially detrimental to nesting turtle populations. Identified habitat sensitivities to SLR will be used to inform the government of Equatorial Guinea to consider the vulnerability of their resident turtle populations and projected climate change implications when planning for future development. To our knowledge this is the first study to predict the impacts of SLR on sea turtle nesting habitat in Africa.

Sea Level Rise Impacts

Climate change and its effect on marine environment, especially ocean warming, acidification and sea level rise, impacts fisheries in different ways. However, fisheries and climate change are regulated by different international management mechanisms, which makes the current fisheries management system face challenges. Realizing this, the present paper is designed to consider whether international law should be introduced to apply better management of fisheries so as to cope with the issues arising from climate change. In addition, the paper highlights the importance of incorporating relevant principles into future fisheries regulations by examining an existing bilateral fishery agreements.
