More than 100 activists gathered at Vegkop Polyculture Farm in Philippi on Thursday, 3 September 2026, for a Cape Town Climate Week event focused on defending the Philippi Horticultural Area (PHA) and the Cape Flats Aquifer from mining and development pressure. According to GroundUp, which reported from the scene, the event centred on food and water security in one of Cape Town’s most ecologically significant areas.
The PHA serves as a natural recharge area for the Cape Flats Aquifer, according to a Water Research Commission case study, making it strategically important for both water security and food production across the city. Residents and farmers have long resisted proposals to mine parts of the PHA and build housing developments on land that filters water back into the aquifer system beneath the Cape Flats.
GroundUp reported that Nazeer Sonday, a long-standing PHA campaigner, addressed the gathering about the community’s fight against development encroachment. His remarks and the attendee count of over 100 participants are confirmed only in the GroundUp report and remain unverified by a second independent source.
Cape Town Climate Week, now in its fifth year, is described by the African Climate Alliance as a city-wide celebration of grassroots solutions to climate change, spatial injustice, food and water insecurity, energy, migration, and gender injustice. The week-long programme directs attention to community-led initiatives rather than top-down policy announcements.
The urgency around aquifer protection is rooted in recent experience. Cape Town’s drought from 2014 to 2018 drove dam levels to dangerously low levels and triggered the Day Zero crisis, when the city came within weeks of shutting off municipal water taps. Research published in the journal Frontiers in Water documents how that crisis exposed the city’s vulnerability and sharpened political attention on alternative water sources, including groundwater.
The PHA’s role as both productive farmland and aquifer recharge zone places it at the centre of tensions between urban development pressures and long-term water resilience. Activists argue that paving over or mining the area would compromise the city’s ability to recharge groundwater supplies during future droughts.
“The battle to preserve the Philippi Horticultural Area wetland and the crucial Cape Flats Aquifer from mining and development was at the centre of a Cape Town Climate Week event on Thursday,” GroundUp reported from the gathering.
What remains unclear is whether any concrete policy commitments or legal challenges emerged from the event, and whether the City of Cape Town plans to formalise additional protections for the PHA. Cape Flats News will follow up with the African Climate Alliance and the City’s environmental management department for further comment.
