In order to be displayed properly, renderers like OsmAnd require that land use areas (e.g. lakes, reservoirs, farmland…) drawn inside a larger land use area (e.g. wood) must be assigned to a shared Relation using inner/outer roles.
Land areas seem to cover both natural=* and landuse=*. Ways/nodes are not affected.
This technique has been used for a long time in my location, but I am surprised to see there has been no global documented consensus on tagging these:
