That is not some sort of brown desert.
zoom out, It is in fact a green area .
The geological formation could be called, a swamp, a wet lands . Basically the surface soil is very often near or below the water table, and so it reaches an equilibrium point of soil and vegetation versus water , in terms of area.
If there is less water area, it dries out slower, so the water level rises, increasing water area again. If there is more water area, it dries out faster, as water evaporates in air, and so water level falls, thus decreasing the water area.
So the equilibrium point.
The largest such area on earth is "Canada" isn't it ?
