To this comprehensive list I would add the need to monitor the health of the water system in the laguna. I expect that the water vegetation distribution has changed because of the periodic blockage and the increase of nitrates in the ground water. The nitrates come from de-compsition of plant matter, manure and particularly agricultural run-off from farming where high nitrogen fertilizers are used. I believe the Melague laguna has become choked with water plants that were not all that abundant years ago. Anoxic events kill the natural processes which would cleanse the laguna in situ.
I come from PEI canada where we have regular anoxic events in our estuarine systems and they do stink. They are also unhealthy for the natural systems dependent on these estuaries
So I would add to the what we need to know is "what to measure and where to measure it"
It might be time to involve some of the local University expertise to start to study the various laguna on this coast and how changes in agriculture practice and population adjacent to them are making changes to the ecosystem
