The sandbanks of the Venice lagoon are typical tabular lands with their
own characteristic ecosystem. The tides regulate the flow of water that
enters and leaves the lagoon, forming with their natural strength minor
canals, called ghebi, which connect the innermost areas to the main
The ghebi have a significant role in the lagoon ecosystem, regulating
the water supply both during high tides, with drainage functions, and
during low tides, allowing the passage of water even in the innermost
areas. They also help mitigate the erosive effect that the incoming
The sandbanks are characterized by colors that change according to the
seasons, the tides and the reflection of sunlight. Its flowers paint the
ground purple when they open and, flanked by ghebi or salt pans, create
a spectacle of colors and geometries that can be admired in a
particular way through aerial photography.
A territory that has unique lagoon and marsh characteristics is
increasingly turning into a part of the sea. In just over a hundred
years, the extension of the salt marshes has drastically reduced,
reaching a reduction in surface area of up to 70%. This is due to the
deviation of rivers, to soil erosion, but above all due to anthropic
The marshy environment is quickly giving way to the sea, seriously
endangering the stability of an environment and of the structures that
men have built over the centuries.
Le barene della
laguna di Venezia sono tipici terreni di forma tabulare con un loro
caratteristico ecosistema. Le maree regolano l’afflusso d’acqua che
entra ed esce della laguna, formando con la loro forza naturale dei
canali minori, chiamati ghebi, che mettono in comunicazione tra loro le
zone più interne alle vie d’acqua principali. I ghebi hanno un
ruolo notevole nell’ambito dell’ecosistema lagunare, regolano l’apporto
idrico sia durante le alte maree, con funzioni di drenaggio, sia
durante le basse maree, permettendo il passaggio dell’acqua anche nelle
zone più interne. Contribuiscono inoltre a mitigare l’effetto erosivo
che hanno le maree entranti. Le barene sono caratterizzate da colori
che cambiano a seconda delle stagioni, delle maree e del riflesso della
luce solare. I suoi fiori dipingono di viola il terreno quando si
schiudono e, affiancati ai ghebi o alle saline, creano uno spettacolo di
colori e geometrie che possono essere ammirate in modo particolare
tramite la fotografia aerea. Un territorio che ha
caratteristiche uniche di laguna e di palude si sta trasformando sempre
di più in una parte di mare. In poco più di cento anni l’estensione
delle barene si è drasticamente ridotta, toccando una riduzione della
superficie anche del 70%. Ciò a causa della deviazione dei fiumi,
all’erosione del suolo, ma soprattutto dovuta all’intervento antropico. L’ambiente
palustre sta velocemente cedendo il posto al mare, mettendo in serio
pericolo la stabilità di un ambiente e delle strutture che gli uomini
hanno costruito nei secoli.
