Charleroi’s bouwmeester says planting trees is now a political choice against urban heat
Charleroi’s master architect Georgios Maïllis has put tree planting at the centre of the city’s response to hotter summers, saying limiting heatwaves in the city is a question of political choices.
Heatwaves turn street design into a public-health issue. Shade, soil and tree canopy affect how residents move, wait, work and recover during hot days, especially in dense neighbourhoods with little private cooling.
The subject is Charleroi’s urban response to heatwaves, centred on comments by Georgios Maïllis, the city’s bouwmeester or master architect, who argues that planting trees to limit urban heat is a political choice. The natural page is Wallonia because the story concerns municipal planning in Charleroi.
Background
Charleroi created its bouwmeester function in 2013 as part of a wider urban renewal strategy. The current debate places climate adaptation inside that same redevelopment agenda: public space is judged not only by appearance or mobility, but by how it performs during extreme heat.
Impact
Regional — The impact is local to Charleroi and relevant across Wallonia’s older urban centres, where paved public spaces, limited shade and redevelopment pressures shape exposure to heat.
Opposing perspectives
- Urban greening advocates
Supporters of rapid planting argue that trees are public-health infrastructure because shade lowers heat exposure for pedestrians, older residents, children and outdoor workers, especially in neighbourhoods without widespread air conditioning.
- Municipal budget and mobility planners
City officials responsible for roads, parking, utilities and budgets face trade-offs: planting mature canopy requires space, maintenance, watering and construction changes that compete with traffic flow, deliveries and other public works.
