What remote sensing datasets exist to help me establish global distribution of recent mangrove loss?

I am compiling a series of historical case studies of transformative adaptation to major environmental changes, such as dryland salinity brought about by land clearing and changes in water availability due to high irrigation diversions and so on. I am keen to learn of examples that provide a perspective on social processes and decision making in relation to adaptive responses by people, particularly that relate to changes in societal values relating to the environment, how knowledge was used to scope choices for adaptation and how rules (legislation, policies, behaviours and norms) either enabled or constrained those choices. Any pointers to relevant literature would be gratefully received.

With the ongoing global changes in the climate, several schools are including environment changes effects on health and disease. Are you giving a place in the curriculum to this critical area?

Most researchers pay attention on temperature and CO2 alternation during life evolution, I mean geological periods, like Paleozoic, Mesozoic and Cenozoic. Is there any authentic data expressing other environmental factors like light, water, and chemical atmosphere component druing the geological periods?

Kindly suggest any libraries/Books/platforms/tutorials for the same.

I am currently looking at the dissappearance of wetlands/marshlands in and around Chennai. What would be the best month to get a good look at the vegetation development. December/january after the north east monsoon has hit the area?

Kind regards

I'm thinking of acquiring imagery of water-bodies and riparian vegetation over a 10year span to try and relate land use with deterioration of water quality

What are best suitable techniques in image processing to identify the real time change in the region of farm and what are the best suitable techniques to identify the real time change in the leaf of a plant to identify the plant diseases?
