“…Knowing the number of subdelta cycles, however, does not inform us about the areal extent or timing of processes for the entire MRBD. Additionally, the complex relationship between the two processes of changing sediment supply and land area serves as a reminder that such land change processes are rarely a consequence of purely geological or purely anthropogenic processes, but rather are a result of the interaction between the two (Brookfield 1999).…”

The Mississippi River basin was developed for agriculture at an unprecedented scale and intensity within the last 200 yr. These changes favored erosion and sediment transport, which were subsequently reduced by soil conservation practices, the trapping of sediment behind large reservoirs, and channel engineering. We discuss the relationship between sediment loading and the growth, loss, and stability of wetlands in the Mississippi River birdfoot delta (MRBD). We report an anthropogenically driven increase in mean suspended sediment concentrations in the Mississippi River below New Orleans, from a modeled 350 mg L 21 (174 3 10 9 kg yr 21 ) at the end of the 18th century to a measured maximum of 675 mg L 21 (348 3 10 9 kg yr 21 ) in the late 19th century, followed by a sharp reduction, and then a period of stabilization at 157 mg L 21 (91 3 10 9 kg yr 21 ) after 1962. Changes in wetland area of the MRBD over the past two centuries reflect variations in sediment supply during periods of increasing, decreasing, and stable sediment loading, and are distinct from wetland loss patterns in other areas of coastal Louisiana. The rapid growth of the MRBD until the 1930s, which has been used as a reference for one of the world's largest wetland restoration efforts, may not be a suitable archetype for the majority of the coast. Additionally, future variation in sediment supply to the MRBD would likely change the total wetland area of the MRBD.

“…Thus, crises arising either within (endogenous) or outside (exogenous) the tourism sector can have a significant impact on tourism often seemingly beyond the control of its managers and executives (Brookfield, 1999;Sonnenberg & Wöhler, 2004).…”

“…People in Malé also perceive environmental challenges as less important compared to the economic situation and social problems. Considering the historical background and current economic dependence on tourism of both islands, this result exposes the lasting marginalization and idealized "paradise" of small [7,100,[103][104][105]. Tackling climate change impacts on small islands must be done in conjunction with research on the changing social and economic fabric of island case studies [106][107][108].…”

Local Perceptions of Climate Change Impacts in St. Kitts (Caribbean Sea) and Malé, Maldives (Indian Ocean)

Small Island Developing States (SIDS) are now experiencing the local consequences of a changing climate, environment, and society. Nonetheless, climate change research frequently remains at regional or national levels. Without locally grounded data, islanders’ perceived impacts of the changes might not be considered, thereby causing difficulties when policy and practice responses are implemented without accounting for local understandings. To contribute to addressing this gap, this study examines perceptions of climate change and associated environmental and social changes in two SIDS case studies: St. Kitts in the Caribbean Sea and Malé Atoll, Maldives in the Indian Ocean. Through these two case studies, we assess perceptions of changing social and natural environments through a closed-question, face-to-face survey. Our results suggest that in both island case studies, communities perceive environmental changes to be happening that demand negotiation with the social changes of daily life. Results also suggest that perceived climate change impacts are only part of the equation, as social and economic impacts reveal two case studies of changing island societies. While the geographic context in each case study differs, this study reveals the perceived impacts of climate change and social changes at a local level, providing valuable insights and angles for formulating policies and actions to deal with the myriad of social and environmental changes affecting SIDS.
