You guys are still missing the important point here.  Erosion only happens with the migration of sediment by... Rain!  and since it never rains on Nia then there's no erosion!  Seriously though a nice undo button is a great way to cover your tracks and or a highly powerful offensive tool.

There's no *** wind on Nia either.  Erosion will cause me to stop playing.  I have a *** load of time, nic and planning tied up on my islandS.  Something I don't want to have to redo like pointless *** walls.

technically speaking, if a planet has an atmosphere it has wind.  And since we have fog on Nia, there is an atmosphere, so there must be wind.  And to further this point,  if there is enough water vapor to form fog, then there is enough vapor to form higher altitude clouds which would then generate rain.

Erosion is not limited to just water.  Erosion can happen from ice, glaciers, snow, wind, water, gravity, and tectonic shift.  So no, erosion does not only happen from rain.

Items in bold are caused by water, or have root cause of water. 

Items in Red Do not CAUSE erosion but actually prohibit it.

Erosion is caused by the migration of sediment over time by water and wind(lols).  Things that help prohibit the migration of sediment are different techniques of stabilization, for example: Plants.  Because after 10 minutes of time, plants magically appear on freshly terraformed areas, it is clear that the freshly terraformed areas are immediately stabilized by root masses in the soil.  Further providing the fact that erosion does not exist in Nia and should not exist.  Also it should be noted that there is no Snow, or Glaciers, or WIND.  Since th fog magically appears we can conclude that high flying clouds magically drop instantly to the ground, and the Wind forced used to guide them would be in a downward pattern.  Causing further stabilization to the land masses by creating a reverse effect on the migration patterns of typical soil.  This is further proven when the fog is magically lifted suddenly.  By what would seem by the FM technique.  What is the FM technique you might ask, well it's F*cking Magic, thats what it is.

So if we are "technically" speaking Martha, I don't think you have enough of a technicial background in erosion control and techniques to even discuss that.  Although googling "Things that cause erosion."  Might make you an expert, in real world applications and in "theory" you have no Idea whats going on.

Erosion by water or wind or whatever takes decades, so not too concerned, if done 'right'. Trying to balance a game on real world effects and arguing about it, won't get us anywhere.

Population erosion is more of a concern.

So if im wrong ville what is

Mass wasting?  yes water CAN play a part in it but NOT ALWAYS. 

Not from google,  From a book I had to read for my geo physics class.
if you'd like to read the book I still have the PDF, and will gladly email it to you?  in most cases yes, water plays a huge part in erosion.

but as I stated before WATER IS NOT THE ONLY CAUSE OF EROSION

I don't really care either way if they implement erosion or not.  I'm strictly here for the violence:)
