“…In the two sub-basins of Marzenego and Dese-Zero, 23 NBS of these types were created. As an example, Figure 2 shows the satellite views of two wetlands (Salzano and Rusteghin) and two buffer strips (Scandolara and Nicolas-selected because of their longterm monitoring activity [52][53][54][55] realized within the basin, which are described more in details in Supplementary Online Materials.…”

When nature-based solutions (NBS) are developed with a primary scope, they also provide simultaneous additional economic, social, and environmental benefits, i.e., Ecosystem Services. A monetary assessment that accounts for these additional benefits is provided by this work, with a focus on Europe. Specifically, this is intended to evaluate nine identified benefits of those wetlands and buffer strips designed to primarily address agricultural diffuse pollution, which must surely be listed among the negative externalities of economic activities that NBS can help resolve. The aim of developing a simplified value transfer methodology for a rapid evaluation of NBS benefits with the adjusted unit Value Transfer method is to create an accessible solution when time, funding, or other constraints prevent the use of highly technical primary monetization approaches. The developed exercise allows us to gather insights from several primary valuation studies and to appropriately transfer the monetary valuation outcomes to new policy sites. In order to reduce the distance from the expected and required concrete achievements of the economic valuations, the study has been integrated with an case study located in the Venice lagoon catchment in Northwestern Italy. The results obtained are to be considered sound, with existing evidence showing that the most valuable benefits of the considered NBS are both water quality and recreation and tourism, to which is added, in the case of wetlands, water supply.

“…These preferential flows allow pumping in the system volumes of irrigation water higher than what would be expected based only on the saturated hydraulic conductivity (Ks). As a consequence, water moves through the soil creating subsurface flows with different velocity (Mastrocicco et al, 2014).…”

“…To better describe the hydraulic behaviour of the system, tracer experiments were performed in 2008 (see Mastrocicco et al, 2014). These results indicate that deep seepage from the shallow aquifer into the underlying alluvial was negligible and as a consequence the input of deep groundwater to the shallow flow system was excluded.…”

“…La conducibilità idraulica misurata tramite slug test differisce sensibilmente (anche di un ordine di grandezza) rispetto a quella teorica attesa per i diversi tipi di suoli. Ciò è imputabile generalmente alla presenza di macro-fessurazioni nei suoli derivanti dalle operazioni di aratura o in alternativa all'effetto degli apparati radicali come descritto in altri studi (Mastrocicco et al, 2013).…”

Sette Fasce Tampone, realizzate secondo le indicazioni tecniche contenute nello Standard di condizionalità 5.2, in diversi ambiti e contesti climatici, sono state monitorate per un periodo biennale, al fine di quantificare la loro efficienza nella rimozione di azoto inorganico disciolto. Tale azoto è costituito per lo più da molecole di azoto nitrico che vengono veicolate principalmente tramite deflussi sub-superficiali da zone soggette a diverse pratiche colturali verso i corpi idrici superficiali adiacenti. Ad eccezione di due casi: i siti di Lodi e Metaponto, in tutti i sistemi monitorati è stata confermata la presenza di deflussi trasversali ai sistemi tampone, permanenti o temporanei, in grado di veicolare inquinanti e con portate variabili fra 919 e 8.590 m3/anno per 100 m lineari di FT. Le differenze di portata sono imputabili principalmente alla diversa superficie dei bacini agricoli afferenti ai sistemi tampone, che nei casi analizzati occupano superfici variabili fra il 3,6 ed il 33,3% del bacino agricolo. Sulla base dei bilanci di massa è emerso che dai campi coltivati giungono ai sistemi tampone percentuali variabili fra l’1,6 ed il 29,4% dell’azoto inorganico applicato. Ad eccezione dei sistemi in cui i maggiori deflussi non hanno alcuna interazione con la rizosfera (deflussi profondi) oppure non attraversano la Fascia Tampone, in tutti gli altri siti si registra un effetto di riduzione dell’azoto fra entrata ed uscita, con percentuali variabili fra il 33 ed il 62 %. Percentuali di abbattimento non elevate sono giustificate dallo scarso grado di maturazione dei siti monitorati, in molti casi recentemente convertiti a Fascia Tampone. Ancora una volta si conferma l’estrema eterogeneità delle risposte di questi sistemi ed il ruolo prioritario delle forzanti idrologiche nel determinarne l’efficacia.Seven buffer strips (BS) adjacent to fresh water bodies, realized according to the technical data contained in the Standard 5.2 of Cross-compliance, located in different areas and climate contexts, were monitored for a period of two years. It was done in order to quantify their effectiveness in removing dissolved inorganic nitrogen conveyed through sub- surface flow from field crops with different cultural practices. Except for two case studies (sites: Lodi and Metaponto) in all monitored systems has been confirmed an outflow, permanent or temporary, through the buffer systems, with flow rates ranging from 919 to 8590 m3y-1 every 100 meters of buffer stip. The differences in flow rate were mainly due to different sizes of agricultural basins related to buffer systems, which in the case studies ranging from 3.6 to 33.3%. Based on the mass balance, was found percentages of applied inorganic nitrogen, flowing from cultivated fields to the buffer systems, varied between 1.6 and 29.4%. In most of the sites was estimated nitrogen reduction between inlet and outlet of BS, with percentages ranging from 33 to 61.9%. The exceptions were the systems with groundwater that: or have no interaction with the rhizosphere (deep flow) or not crossing the buffer zone. Low percentages of removal shall be justified by the young stage of the monitored sites, being in many cases recently converted to buffer strip. This study confirms the extreme variability of these systems efficiency and the key role of hydrology drives its effectiveness.
