As a general principle in OSM we map positively what verifiably exists,
not the lack of something. What you call "bareland" is at odds with
that because it is essentially negatively defined (as land lacking
vegetation). So in terms of choosing tags i would recommend you focus
on positively characterizing what you observe.
In areas of deforestation large areas of bare ground is typically a
transient state that will overgrow again rather quickly (within months
or a few years) with some form of vegetation, ob become regularly
maintained by humans in some form (like farmland).
We also do not have any established tagging for what you
call "artificial surface" because artificial surfaces are created
usually for specific purposes and we typically map them depending on
Whatever tagging concept you choose you should document your plans and
discuss them with the local community beforehand to make sure your
plans are compatible with the mapping and tagging habits of the local
