This is a list of projects organised by Wikimedia Belgium:

SELECT ?wikiproject ?wikiprojectLabel WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  ?wikiproject wdt:P31 wd:Q16695773.
  ?wikiproject wdt:P664 wd:Q18398868.
}

See https://w.wiki/$cN

It has been created by starting Wikidata Query, then entering the search items "wikiproject" and "WMBE" in the Filter section.

Missing Labels

With Wikidata it frequently happens that labels are missing for certain languages.

With Wikidata Query and QuickStatements you can create labels in other languages. This increases knowledge sharing amongst languages. It invites other languages to document "foreign" items. Then descriptions can be added for each of the newly created items.

Example: imagine that you want to create missing lables for Belgian persons.

Copy the following text into https://query.wikidata.org

 SELECT ?item ?itemLabel ?itemDescription WHERE {
  ?item wdt:P31 wd:Q5.
  ?item wdt:P27 wd:Q31.
 
  SERVICE wikibase:label { bd:serviceParam wikibase:language "fr,en,de,pt,es,no". }
  FILTER(NOT EXISTS {
    ?item rdfs:label ?lang_label.
    FILTER(LANG(?lang_label) = "nl")
  })
 }
 ORDER BY ?itemLabel

Download the results.
Generate a QuickStatements transaction file, e.g. using Excel
Now you can automatically create labels.

Tip: Use the Lxx command

Missing Descriptions

 SELECT ?item ?itemLabel ?sexLabel ?beroepLabel ?domainLabel ?ambtLabel ?itemDescription WHERE {
   ?item wdt:P31 wd:Q5.
   ?item wdt:P27 wd:Q31.
 optional{ ?item wdt:P21 ?sex.}

   FILTER(NOT EXISTS {
     ?item schema:description ?itemdesc.
     FILTER(LANG(?itemdesc) = "nl")
   })
 }
 order by ?itemLabel
