It really doesn't need a source. If Venice takes too much water from an aquifer then subsidence is unavoidable. The city is sitting on top of a sponge, after all. This is true for any city that's not built on bedrock (which I believe includes half of Manhattan and Miami. NYC of course draws from the Hudson)
Anyway, as the paper states the subsidence exasperates rising sea levels.
