Malta’s ambitious initiative to introduce green walls across urban landscapes has encountered significant challenges, raising questions about the efficacy and sustainability of such projects. The decision to dismantle three prominent green walls—located at Marsa, Corradino and the Mosta Technopark—underscores the complexities involved in urban greening efforts.

Inaugurated with considerable fanfare between 2020 and 2021, these vertical gardens were envisioned as transformative elements to enhance urban aesthetics and environmental quality. The Marsa installation, for instance, was Malta’s longest green wall, stretching 350 meters and comprising over 27,000 plants. Similarly, the Corradino site featured a substantial green wall aimed at urban embellishment.

However, less than three years post-implementation, these projects have been deemed unsustainable. INDIS, the government’s industrial land management company, cited excessive water consumption that outweighed environmental benefits as the primary reason for discontinuation. This revelation is particularly concerning given Malta’s limited water resources and highlights a critical oversight in the project’s planning phase.

Further complicating the matter is Infrastructure Malta’s recent attempt to salvage the derelict Marsa-Ħamrun Bypass green wall after prolonged neglect, drawing public ire. This eleventh-hour intervention has been widely criticized as a reactive measure rather than a proactive approach to maintaining green infrastructure. The public frustration highlights a broader issue—our tendency to launch flashy environmental projects without long-term commitment to their upkeep.

Financially, the implications of failed green wall projects are significant. The Marsa green wall alone cost approximately €600,000, with the Corradino and Mosta installations costing €163,000 and €128,000, respectively. These figures, which included five-year maintenance plans, now represent sunk costs with little to show in terms of lasting environmental or aesthetic benefits.

These repeated setbacks have drawn sharp criticism from various quarters. The funds could have been more effectively utilized for alternative environmental initiatives, such as extensive tree planting, which might offer more sustainable benefits.

Meanwhile, historic green spaces like Buskett remain neglected. Instead of continuously pursuing new green initiatives that often end up abandoned, authorities should first prioritize the care and rehabilitation of existing natural sites. Buskett, with its centuries-old citrus groves, could benefit immensely from organized restoration projects. Initiatives such as rehabilitating the old citrus trees and engaging school children in fruit-picking activities would not only contribute to conservation but also foster a deeper appreciation for Malta’s natural heritage among younger generations.

Rather than focusing on short-lived, costly projects, Malta must reassess its approach to urban greening. The priority should be preserving and restoring the green spaces we already have, such as Buskett and other neglected areas.

Ultimately, the pursuit of a greener Malta hinges not on grandiose projects but on pragmatic, well-considered strategies that align with the nation’s ecological realities and infrastructural capacities. If we genuinely care about the environment, we must start by safeguarding and nurturing the natural treasures we already possess.
