Abstract:Climate projections agree on a dryer and warmer future for the Mediterranean. Consequently, the region is likely to face serious problems regarding water availability and quality in the future. We investigated potential climate change impacts, alone (for three scenario periods) and in combination with four socio-economic scenarios (for the near future) on water resources in a Mediterranean catchment, whose economy relies on irrigated agriculture and tourism. For that, the Soil and Water Integrated Model (SWIM) was applied to the drainage area of the Mar Menor coastal lagoon, using a set of 15 climate scenarios and different land use maps and management settings. We assessed the long-term average seasonal and annual changes in generated runoff, groundwater recharge and actual evapotranspiration in the catchment, as well as on water inflow and nutrients input to the lagoon. The projected average annual changes in precipitation are small for the first scenario period, and so are the simulated impacts on all investigated components, on average. The negative trend of potential climate change impacts on water resources (i.e., decrease in all analyzed components) becomes pronounced in the second and third scenario periods. The applied socio-economic scenarios intensify, reduce or even reverse the climate-induced impacts, depending on the assumed land use and management changes. OPEN ACCESSWater 2015, 7 1539

Ria de Aveiro is a mesotidal coastal lagoon with one of the largest continuous salt marshes in Europe. The objective of this work was to assess C, N and P stocks of Spartina maritima (low marsh pioneer halophyte) and Juncus maritimus (representative of mid-high marsh halophytes) combined with the contribution of Halimione portulacoides, Sarcocornia perennis, and Bolbochenous maritimus to the lagoon ≈4400 ha marsh area. A multivariate analysis (PCO), taking into account environmental variables and the annual biomass and nutrient dynamics, showed that there are no clear seasonal or spatial differences within low or mid-high marshes, but clearly separates J. maritimus and S. maritima marshes. Calculations of C, N and P stocks in the biomass of the five most representative halophytes plus the respective rhizosediment (25 cm depth), and taking into account their relative coverage, represents 252053 Mg C, 38100 Mg N and 7563 Mg P. Over 90% of the stocks are found within mid-high marshes. This work shows the importance of this lagoon’s salt marshes on climate and nutrients regulation, and defines the current condition concerning the ‘blue carbon’ and nutrient stocks, as a basis for prospective future scenarios of salt marsh degradation or loss, namely under SLR context.

The ecological state of the Sevastopol Bay and the Yuzhnaya Bay is compared by their trophic level using the E-TRIX index. E-TRIX is defined by four state variables, which are strongly correlated with primary production: chlorophyll a, oxygen as absolute % deviation from saturation, dissolved inorganic nitrogen, and total phosphorous. The annual dynamics of biogenic elements is calculated; the one-dimensional water quality model, which has been calibrated for the referred water areas, is used. The annual E-TRIX index variations in the bays are compared; the correlation coefficients between E-TRIX and its parameters are calculated; the contributions of E-TRIX variables are estimated.The annual variation of biogeochemical parameters in the Sevastopol and Yuzhnaya bays has been simulated and E-TRIX index has been estimated. The calculations have showed that on the average the Yuzhnaya Bay has higher trophic level: the average E-TRIX index equals 4.47. In the Sevastopol Bay, the average E-TRIX value equals 4.01. The maximum values of the index have reached 5.53 for the Yuzhnaya Bay and 4.55 for the Sevastopol Bay. However, when the level of phosphates concentration which are the main limiting nutrient elements in the Sevastopol Bay is higher than in the Yuzhnaya Bay (from early July to middle August), the trophic index in the Yuzhnaya Bay is lower than in the Sevastopol Bay.The relative contribution of components in the E-TRIX index has been estimated. It has been revealed that the main factor determining the trophic level in the Sevastopol and Yuzhnaya bays water is the concentration of dissolved inorganic nitrogen. The contributions of the other components in the E-TRIX index are equivalent.
