“…These studies are the most recent on coastal lagoons, and in our study area have dealt especially with Venice [68], but are of concern in general in all coastal lagoons, especially those with urban settlements on their shores [69]. The results show that the level of the lagoons will also rise, as well as there being an increase in temperatures and salinity (especially in those that are less open to the sea) and, therefore, there will be a change in species [70] and a disappearance of lagoons that lose the coastline. The changes that lagoons undergo due to extreme events, such as floods [71,72] or pollution episodes, are also important [73], and in many cases lead to the implementation of restoration measures [74] in order to preserve, in the best possible condition, these places of ephemeral life in geological time.…”

Coastal lagoons are an established priority habitat in the European environment because of the biological communities that inhabit them. Their origin is related to the transport of sediments from a nearby river or the movement of sands by the marine currents that produce the closure of a gulf. Therefore, they are recent geological formations, which also disappear quickly if environmental conditions change. The 37 coastal lagoons with a surface area greater than 10 km2 located in the Mediterranean basin have been identified. Fishing has been the traditional use of these lagoons, in addition to their use as a navigation harbor when they are open to the sea. Pollution, quality problems and their consequences are the most studied topics in recent publications. Sentinel-2 images taken in the summer of 2020 have been used to study water transparency, suspended matter and chlorophyll a concentration. The result was that only six of them are in good ecological condition, but most of them are eutrophic due to the impacts on their environment and the inflow of poor quality water. The cultural values of these lagoons must also be protected and preserved.

“…Egypt could run out of freshwater resources by the year 2025 as recently reported by the United Nations (WMO, 2017;Yassen et al, 2020). Global climate change can affect the surface temperature of the atmosphere and rainfall patterns causing drought or flash flooding worldwide (Shalby et al, 2021). This can cause disturbances in groundwater hydraulics and increase seawater seepage in the coastal agricultural land and groundwater aquifers particularly in Egypt (Ketabchi et al, 2016;Omar et al, 2021).…”

Impact of Water Seepage of New Suez Canal on Soil Properties of El-Amal Area, Ismailia East, Egypt

Seawater seepage poses a major problem for agriculture in Egypt's coastal areas. In 2020, a 285 Faddan area in El-Amal, Ismailia East was selected as a representative soil model for Egypt's New Suez Canal region to investigate the impact of seawater seepage on soil properties and identify the responsible factors for land degradation, with an emphasis on suitable adaptations to land limitations and climate stressors. Seawater changes the behavior of soil and creates geotechnical problems that enhance soil alkalinity and salinity value. Five soil mapping units (SMUs) were identified with moderately to shallow soils dominating, in a detailed soil survey that was conducted in the field to conduct pedomorphological and physicochemical investigations. The water table had raised by 50-100 cm within the soil pedons. Approximately 45.4 Faddans were recognized as sabkhas due to the inundation of lowlands with seawater. Most study lands (217.2 Faddan) were unsuitable for cultivation due to the higher limitations of salinity, alkalinity, soil structure, and poor drainage under saturation conditions. The salinity of saturated soil reached 29.60 dS/m, posing a major challenge to agriculture. The results indicated that the pedomorphological and physicochemical properties of most study soils had degraded and become unsuitable for cultivation, which was linked to the seawater seepage. It is predicted that the rest lands (SMU1 and SMU2) and other adjacent lands to the study area are expected to change into desertified lands in the future due to continuous seawater seepage. The New Suez Canal's seawater seepage caused the cultivated fruit trees and other vegetation in the study area to dry up and die. Climate change-induced seawater seepage and drought were the direct causes of soil salinization in the study lands. To achieve long-term sustainability and avoid maladaptive outcomes, an urgent need to adopt an integrated approach for large-scale investments in Egypt's farming sector is urgently needed for effective policymaking toward achieving food security, with it being recognized that climate change has adverse effects and challenges to the soil resources in Egypt, and therefore, the sustainable planning of natural resources in coastal areas should be further studied and thoroughly managed. Adopting local adaptation actions and strategies for incremental, systemic, and transformational changes at the farm and on large scales in the agricultural sector is critical. The transformational adaptation actions are the suitable practices, followed by incremental and systemic adaptations to combat the agricultural limitations and climate change stressors in the current study lands.

“…Siniscalchi, Kopprio, et al (2018); Siniscalchi et al (2019); and Siniscalchi, García Prieto, et al (2018) developed a hydrological model within a dynamic optimization framework for flood management of a salt lake in a semiarid region in Argentina. Shalby et al (2020) proposed models for climate change effects on a coastal lake in Egypt, yet they did not address the lake management problem within an optimization approach.…”

Sustainable long‐term mitigation of floods and droughts in semiarid regions: Integrated optimal management strategies for a salt lake basin

2022

We present a management project for the mitigation of extreme climatic events in the frame of cyclic wet and dry periods in the semiarid Pampean region of Argentina. The developed methodological approach allows quantitative planning of strategies to tackle the effect of recurrent floods and droughts in a salt lake basin through the formulation of an optimal control problem, which constitutes a novel approach to ecohydrological systems management. The control variables correspond to (i) diversion flows from a lake tributary to an artificial freshwater reservoir to damp lake flooding, (ii) freshwater flows from the reservoir to the salt lake to keep its salinity at desired values and (iii) freshwater flows to irrigate crops during drought periods. Further, we address the economic valuation of ecosystem services in the basin. Quantitative results provide useful insights on optimal management strategies and the effects of their implementation, as well as their impact on the valuated services in the watershed under study.
