“…Human occupation dates back to 3000 Before Present (BP), whereas modern fishermen settled the area during the first half of the past century, mainly along the tributaries and on the sand barrier [17]. After 1950, fishing communities on the sand barrier were established, and housing and tourism developed, mostly on the southern area of the system close to the ocean [18][19][20].…”

Paleoenvironmental reconstructions are increasingly being used in conservation biology, ecosystem management, and evaluations of ecosystem services (ES), but their potential to contribute to the ES risk assessment process has not been explored. We propose that the long-term history of the ecosystem provides valuable information that augments and strengthens an ES risk assessment and that it should be considered routinely when undertaking risk assessments. We adjusted a standard ecosystem-based risk management (EBRM) protocol to include paleoenvironmental data, and tested the modified approach on two coastal lagoons in South America. Paleolimnological reconstructions in both lagoons indicate that salinity and nutrients (in Laguna de Rocha), and salinity (in Ciénaga Grande de Santa Marta), as controlled by hydrologic connectivity with the ocean and freshwater tributaries, have been the key variables behind ecosystem’s function. This understanding, applied to inform various components and steps in the EBRM protocol, suggests that the maintenance of hydrological connections should be a management priority to minimize risk to ES. This work illustrates the utility of including paleoenvironmental data in an EBRM context and highlights the need for a more holistic approach to risk management by incorporating the long-term history of ecosystem function.

“…The analysis of both proposals has been integrated with own data and complemented with results of recent local studies in five estuarine and oceanic sectors of the Uruguayan coast for the National Environmental Agency. It additionally includes a specific multidisciplinary study on the coast from the Rocha lagoon (Conde et al 2015). The selection of the type of model (monotonic vs. oscillatory) is relevant, as the first case implies the existence of a trend of prograding coasts and in the second case, coasts oscillate over time between prograding and erosive (regressive).…”

A study of the position of the coastline was performed from the recent past (50 years) to Holocene ages (about 5000 years ago) in La Pedrera-Cabo Polonio coastal sector, in the southeast of Uruguay. Some persistent geoforms, such as marshes, located at very low elevations present lowest displacement of the recent coastline. Other recent landscapes, such as coastal gullies, developed on Late Pleistocene sediments are associated with a progradational coast in the short term. The geomorphological cartography was a useful tool for coastal management in the scenario of 10 cm sea-level rise per century and a coastal retreat of about 1 m per year. The analysis of coastline evolution provides information to assess the best measures to prevent coastal erosion and identify vulnerable areas. The presence of an escarpment (paleo coastline) located around + 10 to + 5 m above the current sea level appears to be the most appropriate criterion of minimum setback distances from current coastlines for constructions.

“…Lakes, estuaries, and lagoons around the world are degrading because of increasing human pressure, particularly due to water and sediments pollution and climate-change-related effects [1][2][3]. Among the coastal tidal systems, lagoons are probably the most threatened [4,5]. Lagoons occur along about 13 percent of the world's shorelines [6] and play a fundamental role as morphological and biodiversity hotspots, providing valuable ecosystem services as for example refuge and nesting for a wide variety of wildlife, including mammals, marine birds, and migratory waterfowl.…”

Remote Sensing for Optimal Estimation of Water Temperature Dynamics in Shallow Tidal Environments

et al. 2019

Given the increasing anthropogenic pressures on lagoons, estuaries, and lakes and considering the highly dynamic behavior of these systems, methods for the continuous and spatially distributed retrieval of water quality are becoming vital for their correct monitoring and management. Water temperature is certainly one of the most important drivers that influence the overall state of coastal systems. Traditionally, lake, estuarine, and lagoon temperatures are observed through point measurements carried out during field campaigns or through a network of sensors. However, sporadic measuring campaigns or probe networks rarely attain a density sufficient for process understanding, model development/validation, or integrated assessment. Here, we develop and apply an integrated approach for water temperature monitoring in a shallow lagoon which incorporates satellite and in-situ data into a mathematical model. Specifically, we use remote sensing information to constrain large-scale patterns of water temperature and high-frequency in situ observations to provide proper time constraints. A coupled hydrodynamic circulation-heat transport model is then used to propagate the state of the system forward in time between subsequent remote sensing observations. Exploiting the satellite data high spatial resolution and the in situ measurements high temporal resolution, the model may act a physical interpolator filling the gap intrinsically characterizing the two monitoring techniques.
