THE implementation of the Union Square upgrading project has successfully reduced surface temperatures in the area by nearly 24°C.
Penang Infrastructure, Transport and Digital Committee chairman Zairil Khir Johari said the significant temperature drop has not only improved the microclimate comfort level but also created a cooler, more pleasant and inclusive public environment.
“This project stands as one of the key success stories under the Penang Nature-Based Climate Adaptation Programme (PNBCAP), showcasing how user-friendly community spaces can be created within the core zone of the George Town Unesco World Heritage Site.
“Through nature-based design elements such as the replanting of 37 trees, the installation of permeable pavements, and the addition of decorative water features, the surface temperature in this area has lowered by almost 24°C compared to before the upgrading works were carried out.
“This demonstrates that small-scale urban design interventions can have a meaningful positive impact on urban social well-being and climate adaptation,” Zairil (PH–Tanjong Bunga) said in response to an oral question from Wong Yuee Harng (PH–Pengkalan Kota) at the Penang Legislative Assembly today.
Zairil added that an urban farming programme has also been introduced at Lebuhraya Rose, featuring agroponic, hydroponic and sea grape cultivation facilities.
“This programme is carried out in collaboration with Universiti Sains Malaysia (USM) and the Centre for Marine and Coastal Studies (CEMACS).
“Besides functioning as an urban agriculture learning centre, the programme also strengthens community knowledge and skills in urban farming, while supporting local-level food security initiatives.
“Interestingly, retirees are involved as the primary caretakers of the farming site, assisting with daily maintenance while earning supplementary income from the produce,” he said.
Further elaborating, Zairil said an age-friendly park has also been established at Lengkok Nipah, following a public engagement session with local residents in 2024.
“Residents proposed transforming the former parking and container storage site into a green community space that is friendly to senior citizens.
“Through this initiative, 67% of the concrete surface area, spanning 3,365 square metres, has been converted into greenery.
“In addition, 12 new trees from the species Samanea saman and Syzygium gratum were planted as part of efforts to enhance natural shade and strengthen the urban ecological balance.
“This approach has successfully created a greener, safer and more inclusive environment, in line with PNBCAP’s objectives of enhancing urban green connectivity and promoting community well-being across all age groups,” he added.
