Penang is a state located in north-western Peninsular Malaysia with an area of 1,049 km2. It comprises two local authorities, Penang Island and the mainland. The former is further divided into five administrative districts which are further divided into mukims (sub-districts). Two urban mukims located on the island – George Town and Bayan Lepas – are the focus of the proposed nature-based solutions (NBS) climate adaptation programme. The programme was launched in 2022 by UN-Habitat in collaboration with the Ministry of Environment and Water (KASA) of Malaysia, Penang Island City Council (Majlis Bandaraya Pulau Pinang - MBPP), Department of Irrigation and Drainage (Jabatan Pengairan Dan Saliran - JPS) and Think City (a wholly-owned subsidiary of Khazanah Nasional Berhad (the sovereign wealth fund of the Government of Malaysia)). (Ref 1) The implementation of the project responds to several challenges posed by climate change including heatwaves and flooding (Ref 4). The main goal of the programme is to enhance urban resilience and reduce human and ecosystem health vulnerability to climate change impacts and extreme weather events by implementing nature-based solutions (NBS) such as tree-lined streets, pocket parks, green parking spaces, green facades and rooftops, urban agriculture and blue-green corridors to reduce surface temperatures and stormwater runoff, as well as to increase social resilience and build institutional capacity (Ref 1, 3).

Focus
Project objectives
Implementation activities
Climate-focused activities
Climate change adaptation:
- Increase or improve urban vegetation cover to help reduce outdoor temperature
- Implement green walls or roofs to lower indoor temperature and provide insulation
- Implement sustainable urban drainage infrastructure (e.g. to make space for water)
- Increase the use of climate-resilient plant species (resistant to drought, fire, and pests)
Climate change mitigation:
- Increase green urban nature for carbon storage (wetlands, tree cover)
- Install vertical or horizontal artificial surfaces that help with carbon storage and cooling
- Improve carbon sequestration through selection of more adaptable species
- Raise public awareness of behaviours, lifestyle and cultural changes with mitigation potential
