Naples Needs 200,000 Trees to Combat Heat Islands, Federico II Study Reveals
Naples, June 19 – A study conducted by Federico II University in Naples has highlighted the critical need for 200,000 new trees to mitigate the effects of urban heat islands and provide relief from scorching summer temperatures. The research, carried out by the Department of Engineering, underscores the urgency of a massive reforestation plan for the city.
Urban heat islands are a significant concern in Naples, where city asphalt absorbs and re-emits solar energy, leading to extreme thermal conditions for pedestrians. Experts involved in the study estimate that temperatures in historic paved areas can reach close to 40 degrees Celsius, posing a serious health risk, particularly to the elderly and children.
Critical Areas Identified by the Study
The study identified three primary critical zones within Naples, based on building density and the vulnerability of their resident populations:
- Quartieri Spagnoli: Characterized by dense construction and narrow streets, trapping heat.
- Pianura: Another area with significant heat island effects.
- Piazza Garibaldi: Large, open, paved spaces contribute to higher temperatures.
Researchers have mapped these territories and are simulating various climate adaptation solutions to understand their potential impact. The findings emphasize that while spring may not always bring warmth, summer’s intense heat puts vulnerable populations at risk.
Limitations of Current Urban Reforestation Plans
Palazzo San Giacomo, the municipal government, has recently invested 5.5 million euros in planting over 9,000 new trees. Additionally, Councillor Vincenzo Santagada announced a project to plant 27,000 trees to de-impermeabilize areas like Soccavo and the Vallone di via Cilea. Santagada stated, “This is the first time that Naples has intervened in such a decisive and widespread manner.”
However, the Federico II study suggests that these efforts, while commendable, are insufficient to produce widespread benefits. The current scale of intervention is deemed too limited to significantly impact the city’s overall temperature.
Optimal Scenario for Citizen Well-being
Computer models developed by Professor Carmela Gargiulo demonstrate the fragility of the current interventions. To achieve widespread cooling across the city, approximately 180 hectares of permeable soil are required. Gargiulo noted, “In contrast, more massive interventions allow for a more widespread reduction in temperatures.” Architect Simona Panaro echoed this sentiment, calling for a radical cultural shift away from excessive concrete use to protect public health.
The study’s findings provide a clear roadmap for Naples to address its urban heat island problem. A substantial increase in tree planting and the creation of more permeable surfaces are crucial steps towards a cooler, healthier city for all its residents.
