Q. What are the key indicators to assess the sustainability of a Ramsar wetland (Ramsar site) for instance ecological condition, biodiversity status, habitat quality, productivity, environmental settings, ecosystem service, overall status of the wetland etc. What factors should considered to assess to monitor the conservation and sustainability of wetlands over time? Seeking suggestion in light of the RAMSAR convention on wetlands?
Main focus stays on biodiversity, sustainable production, values of ecosystem service, ecological parameters along with community engagement, protection measures for most ecologically valuable natural resources.
I would say cultural/spiritual value should not be forget and tourism issues has to be given priority. Of course Biodiversity value is not to be misssed. Based on my experience from lowland Ramsar Site, socio-cultural issues and prospective economic opportunities should be given focus.
