“…Also, other feedback may represent a matter of concern because the loss of landscape elements might result in the risk of losing ESs related to them (Grizzetti et al, 2019;Rova et al, 2022). For example, the tendency to conserve saltmarshes in the groups H and M can help in maintaining a high supply for regulating ESs (Stocco et al, 2023;Stürck et al, 2015) and provisioning ESs as well. On the contrary, the replacement of saltmarshes with consolidated and built-up land, as shown in group R, may result in the loss of ESs that are significant on a broader scale.…”

“…Even if the valli da pesca are today artificial ecosystems, managed to maximize one or a few Ecosystem Services (ESs), they still provide ESs belonging to different categories along with the maximized one. Recently, they have been shown to contribute substantially to the ESs budget of the whole lagoon and act as decisive conservational areas (Stocco et al, 2023).…”

Coastal lagoons have long been subject to continuous changes caused by mutual interactions with human activities. Monitoring such changes becomes critical, particularly when modifications in landscape and land cover classes can affect their capacity to ensure Ecosystem Services (ESs). In the Venice lagoon, some confined areas called “valli da pesca” supply provisioning ESs, namely aquaculture and hunting, but also other ESs that are important for the entire lagoon, such as regulating and cultural ones. Being heavily modified ecosystems under human control, valli da pesca underwent considerable morphological evolution depending on the maximized ES and the applied management. Using remote sensing data from different sources, we reconstructed changes in land cover and landscape elements in valli da pesca over the last century. By calculating landscape indicators related to land, saltmarshes, and water, we found that landscape features were initially similar for all the valli da pesca. Then, a process began between 1975 and 1987, in which management devoted to maximizing different ESs shaped the land cover in specific patterns. This study confirms the importance of these areas in the context of the entire lagoon and require for monitoring their land cover changes. Remote sensing data represent an important source of historical data to deepen the knowledge about human-Nature interactions, for keeping trace not only of the landscape evolution but also of the dynamics in the ESs supply in response to human interventions.

The Venice lagoon—the largest Mediterranean coastal lagoon—is characterized by the presence at its edges of 31 “valli da pesca”, types of artificial ecosystems that mime the ecological processes of a transitional aquatic ecosystem. Constituted by a series of regulated lakes bounded by artificial embankments, the valli da pesca were established centuries ago to maximize provisioning Ecosystem Services (ESs), such as fishing and hunting. As time passed, the valli da pesca underwent an intentional isolation process leading to private management. Nonetheless, the valli da pesca are still exchanging energy and matter with the “open’ lagoon and today represent an essential element within the context of lagoon conservation. This study aimed to analyze the possible effects of artificial management on both ESs supply and landscape arrangements by assessing 9 ESs (climate regulation, water purification, lifecycle support, aquaculture, waterfowl hunting, wild food, tourism, information for cognitive development, and birdwatching), along with eight landscape indicators. Obtained results suggested that the valli da pesca are today ruled under five different management strategies, according to the maximized ES. Management conditions influence the landscape pattern and achieve a series of “side effects” on the other ESs. The comparison between the managed and abandoned valli da pesca highlights the importance of anthropogenic interventions for conserving these ecosystems, as the abandoned valli da pesca show a loss of ecological gradients, landscape heterogeneity, and provisioning ESs. Nevertheless, the persistence of intrinsic geographical and morphological characteristics still prevails regardless of intentional landscape molding. The result is that the provisioning ESs capacity per unit area is higher in the abandoned valli da pesca than in the open lagoon, emphasizing the importance of these confined areas of the lagoon ecosystem. Considering the spatial distribution of multiple ESs, the provisioning ESs flow that does not occur in the abandoned valli da pesca seems to be replaced by the flow of cultural ESs. Thus, the ESs spatial pattern highlights a balancing effect between different ESs categories. The results are discussed considering the trade-offs generated by private land conservation, anthropogenic interventions, and their relevance for the ecosystem-based management of Venice lagoon.
