OSM data was download from geofabrik on the 10/10/2017.
Tag list inspired by the "land-use" preset of OSM-Bright
waterway=riverbank; landuse=basin,reservoir,park,forest,residential,retail,commercial,industrial,railway,cemetery,grass,farmyard,farm,farmland,wood,meadow,village_green,recreation_ground,allotments,quarry,orchard,vineyard,greenhouse_horticulture; leisure=park,garden,playground,golf_course,sports_centre,pitch,stadium,common,nature_reserve; natural=wood,land,scrub,wetland,water,heath,grassland; highway=pedestrian,footway; amenity=university,school,college,library,fuel,parking,cinema,theatre,place_of_worship,hospital; place=island; aeroway=aerodrome,helipad,apron
Note that many "land-use" polygons superimpose to each other.
The deprecated `wood=*` tags are not considered here.
See this discussion https://help.openstreetmap.org/questions/17501/when-mapping-polygons-surrounded-by-streets-should-they-share-nodes-or-be-traced-separately on the OSM forum
This allow more features to be mapped in the future (hedges, ditches, ...)
Geographic features are digitalized with keeping their real ground footprint
The "OSM land-use" database is not continuous

Why not? (it depends)
See this discussion on the OSM forum?
Arable land: landuse=farmland + crop=*
Grazed meadows: landuse=meadow + meadow=agricultural + animal=yes
Hay meadows: landuse=meadow + meadow=agricultural + crop=grass
landcover=* tags are not rendered
natural=* tags are often pure land-use (and not natural features, at least in Belgium).
