A municipal government in Karachi is experiencing severe urban heat island effects with temperatures regularly exceeding 45°C. City planners want to apply a nature-based solution recognized in international climate frameworks. Under the Paris Agreement and COP decisions, which approach would qualify as both a mitigation and adaptation co-benefit measure for urban heat?
Q1. A municipal government in Karachi is experiencing severe urban heat island effects with temperatures regularly exceeding 45°C. City planners want to apply a nature-based solution recognized in international climate frameworks. Under the Paris Agreement and COP decisions, which approach would qualify as both a mitigation and adaptation co-benefit measure for urban heat?
Answer: Expanding urban forests and green corridors to simultaneously sequester carbon and reduce ambient temperatures through evapotranspiration
Explanation: Urban forests and green corridors function as nature-based solutions (NbS) recognised under Paris Agreement Article 5 and subsequent COP decisions, simultaneously sequestering carbon (mitigation) and lowering ambient temperatures through shading and evapotranspiration (adaptation). This dual co-benefit makes them uniquely eligible for both mitigation and adaptation climate finance streams.
