La Ferme de la Trèflerie (temporary urban farm, Dames Blanches, Brussels)
Woluwe-Saint-Pierre, Brussels, Belgium · Operator: La Ferme d'Anjou ＋ Le Début des Haricots asbl（citydev.brussels が SLRB・ウォリュウェ＝サン＝ピエール市と調整）
Overview
A Brussels example of "meanwhile" use: 2.5 hectares awaiting housing development are opened for a few years as a site for urban agriculture, biodiversity and community activity. Meadows, orchards, wetland, woodland and aromatic gardens on the site are used as they are, layering farming, nature observation and education on one plot.
Citizen participation
The farm is run as a "mosaic of activities" — vegetable plots alongside beekeeping, cut flowers, a seasonal nursery, sensory gardens, sheep grazing and educational workshops. Light infrastructure such as shelters and dry toilets keeps the site open to the public.
Operating model
The land belongs to SLRB (the Brussels regional housing company) and is earmarked for a future eco-quartier. Until that development starts, citydev.brussels — working with SLRB and the municipality of Woluwe-Saint-Pierre — has opened the site as a temporary occupation. It was inaugurated in September 2025 with a minimum duration of four years. It is run by the agroecological farm La Ferme d'Anjou together with Le Début des Haricots asbl, a Brussels non-profit that has worked on food and environmental awareness since 2005.
Impact
The point of the case is that the gap before development is not left idle but turned into a farm open to the neighbourhood, giving residents a period of engagement with the land ahead of the permanent real-estate project. It opened only in September 2025, so participation figures are not yet available.
Land tenure
Temporary occupation of SLRB-owned land, inaugurated September 2025 for a minimum of four years, until the planned eco-quartier development begins.
