“…In the RdlP estuary (Argentina-Uruguay), environmental variations are likely to modify plankton and fish distributions and abundances. The expected rainfall increase and southeastern winds and sea-level increase for 2050 will have contrasting effects as following: decreased/increased seawater intrusion/salinity and inward/seaward displacement of the EFS [ 38 , 39 ]. Together with the increased water temperature, they would affect the mixing-stratification cycle, primary productivity and oxygen levels in the estuarine front [ 37 , 38 ].…”

“…However, paying more attention to prevention and readiness by improving observation–early-warning–response systems, complemented by suitable government policies, the following measures may also be considered and implemented, as also suggested by [ 39 , 48 , 72 ], among others: Adaptive fisheries management, ecosystem-based approach and fishery co-management to reduce the pressure on fish stocks; Dam management to prevent overflows; In estuaries, participatory scenario planning defines adaptation actions under uncontrollable factors and extreme events (e.g., extratropical cyclones and severe droughts); Adjustments in coastal management plans to cater to the estuaries’ increased fragility (e.g., limiting new construction sites or steering economic activities to minimise their impacts on estuary ecosystems). …”

“…For the RdlP estuary, the historical environmental and hydrological data ranged from 1981 to 1999 (e.g., [ 37 ]), and for hydrology, plankton and fisheries from the 2000s to the present [ 46 , 47 ]. In addition, recent climatic, environmental and hydrological data were included (e.g., [ 38 , 39 , 40 , 48 ]).…”

It is well-known that climate change significantly impacts ecosystems (at the macro-level) and individual species (at the micro-level). Among the former, estuaries are the most vulnerable and affected ecosystems. However, despite the strong relations between climate change and estuaries, there is a gap in the literature regarding international studies across different regions investigating the impacts of climate change and variability on estuaries in different geographical zones. This paper addresses this need and reviews the impacts of climate change, variability and extreme weather on estuaries. It emphasises the following: (i) a set of climate parameters governing estuarine hydrology and processes; and (ii) a sample of countries in Asia (Bangladesh), Europe (Portugal) and South America (Uruguay). We reviewed the influences of the climatic drivers of the estuarine hydrology, ecological processes and specific species in estuarine communities across the selected geographical regions, along with an analysis of their long-term implications. The key results from the three estuaries are as following: (i) Hilsa fish, of which the catches contribute to 10% of the total earnings of the fishery sector (1% of GDP), are affected by climate-forced hydrological and productivity changes in the Meghna; (ii) extreme droughts and short-term severe precipitation have driven the long-term abundance and spatial distribution of both fish larvae and juveniles/adults in the Mondego; and (iii) the river inflow and fluctuations increases since the early 1970s have contributed to variations in the salinity, the stratification, the oxygen, nutrient and trophic levels and the spatial pattern for the life stages of planktonic species, fish biomass and captures in the Rio de la Plata. The results suggested that immediate action is needed to reduce the vulnerability of estuaries to climate stressors, mainly the changing river flows, storms and sea-level rise. As a contribution to addressing current problems, we described a set of adaptation strategies to foster climate resilience and adaptive capacity (e.g., early-warning systems, dam management to prevent overflows and adaptive fisheries management). The implications of this paper are two-fold. Firstly, it showcases a variety of problems that estuaries face from changing climate conditions. Secondly, the paper outlines the need for suitable adaptive management strategies to safeguard the integrity of such vital ecosystems.

“…The promotion of information about climate to coastal inhabitants is therefore important to improve their preparedness against disasters regarding agricultural activities. It was found that early warning systems for climatic hazards in coastal areas save lives and agriculture, as well as improving adaptive capacity [152]. Information about climate change can be sent through several types of social networks in coastal communities, ensuring a greater exchange of climate change information [153].…”

Sustainability of Coastal Agriculture under Climate Change

Climatic and non-climatic stressors, such as temperature increases, rainfall fluctuations, population growth and migration, pollution, land-use changes and inadequate gender-specific strategies, are major challenges to coastal agricultural sustainability. In this paper, we discuss all pertinent issues related to the sustainability of coastal agriculture under climate change. It is evident that some climate-change-related impacts (e.g., temperature and rainfall) on agriculture are similarly applicable to both coastal and non-coastal settings, but there are other factors (e.g., inundation, seawater intrusion, soil salinity and tropical cyclones) that particularly impact coastal agricultural sustainability. Coastal agriculture is characterised by low-lying and saline-prone soils where spatial competition with urban growth is an ever-increasing problem. We highlight how coastal agricultural viability could be sustained through blending farmer perceptions, adaptation options, gender-specific participation and integrated coastal resource management into policy ratification. This paper provides important aspects of the coastal agricultural sustainability, and it can be an inspiration for further research and coastal agrarian planning.
