The following layers provide historical information on vegetation cover change in Singapore and its driving forces, such as deforestation and reforestation, the creation of nature reserves, the expansion of plantation economies, soil types, hydrogeology, and geological formations.

Such vegetation cover change was influenced by rainfall and extreme weather events (on this topic see layer subset B.) and shaped mosquito habitats and malaria transmission (on this topic see layer subset C.)
The following layers provide historical meteorological information on rainfall and extreme weather events in Singapore: the great drought of 1877 (inspired by a severe El Niño event), the drought of 1911 (also inspired by an El Niño event), and rainfall in 1912 (a regular year).

Such rainfall and extreme weather events influenced vegetation cover change (on this topic see layer subset A.) as well as malaria epidemics (on this topic see layer subset C.)
Layers B02-B13 provide rainfall data on 1877 (drought year) and can be combined with B39 and B40. Layers B14-B25 provide rainfall data on 1911 (drought year) and can be combined with layers B40 and B38. Layers B26-37 provide rainfall data on 1912 (regular year) and can be combined with layers B40 and B38.
The following layers provide historical information on mosquito breeding grounds, mosquito works, and malaria cases in Singapore, which influenced the incidence of malaria epidemics and local outbreaks.

Mosquito habitats and malaria transmission were also shaped by vegetation cover change (on this topic see layer subset A.) and rainfall and extreme weather events (on this topic see layer subset B.).
