Hi all,
I haven't had a look at the area so I can be wrong, but having lived for
years in Sahelian cities *I would *NOT* use leisure=garden*, as this is
all but for leisure.
In western African cities these garden serve the essential use of
feeding people.
All the fresh fruits and vegetables you find on markets in these cities
are locally produced.
Fridges, transportation and all the logistics we are used to in Europe
or the USA to bring fresh stuff into our cities from all corners of the
world (with an obvious environmental impact...) are simply not reliable
when transposed to Africa.
Hence the need for local production.
And again they are not into "leisure gardening" this is a serious and
for many a full-time activity, their jobs.
This said, many thanks to you all for your contribution. The map has
greatly improved in this region of the world recently, and weren't be
me, my comment would have been brought forward or things amended by some
members of the young but dynamic OSM local chapters. They too are doing
tremendous work mapping in difficult conditions (logistics, again, and
for some political unrest, other threats like uncontrolled armed groups
or Ebola...).
Their contribution is of great value as you will agree there is nothing
like on-site expertise.

Hi Blake and HOT
Thank you for your insight.
I will try to follow your advice on "make that a proper multi polygon".
I realize 'small gardens' is a bit of a stretch.
These few parcels are less than 100 m x 100 m with crop patches
typically of 10 to 20 m so I thought they might be some kind of
collective urban gardens.
But I don't know how to tag this.

OK I have been lazy! ;) That fits quite well:
Community gardens
These are patches of land usually covering one or two city blocks
where community members can grow their own produce on an individual
plot.garden:type
<http://wiki.openstreetmap.org/w/index.php?title=Key:garden:type&action=edit&redlink=1>=* is
relatively well-used (see taginfo
<http://taginfo.openstreetmap.org/keys/garden%3Atype>) and we include
it here to make the garden explicitly a community garden, not simply a
garden that is in a city and might be publicly accessed.
* leisure <http://wiki.openstreetmap.org/wiki/Key:leisure>=garden
<http://wiki.openstreetmap.org/wiki/Tag:leisure%3Dgarden>
* garden:type
<http://wiki.openstreetmap.org/w/index.php?title=Key:garden:type&action=edit&redlink=1>=community
<http://wiki.openstreetmap.org/w/index.php?title=Tag:garden:type%3Dcommunity&action=edit&redlink=1>
* access <http://wiki.openstreetmap.org/wiki/Key:access>=*
So I can leave it as landuse=farmland knowing the small surface speaks
for itself.
Second option is leisure=garden + garden:type=community.
What do you reckon?

You are right that 'farm' is deprecated. And also from the wiki:
landuse <http://wiki.openstreetmap.org/wiki/Key:landuse>=farmland
<http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dfarmland>: for farm
land (i.e. areas used for tillage and pasture; animals, vegetables,
flowers, fruit growing).
landuse <http://wiki.openstreetmap.org/wiki/Key:landuse>=farmyard
<http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dfarmyard>: for area
with farm buildings (like farmhouses, dwellings, farmsteads, sheds,
stables, barns, equipment sheds, feed bunkers, etc.)
Knowing that,
I would then use landuse=farmyard for the yard of the bigger farms;
this would be surrounded by big landuse=farmland.
A smaller farm on the contrary would be a building, maybe no real yard
and a landuse=farmland.
