Main Body
Underlying factors contributing to UHI:
(i) Concretisation of areas — roads, pavements, open areas.
(ii) Reduction in trees and green spaces like parks that absorb heat.
(iii) Tall structures that increase surface area for heat absorption.
(iv) Greater heat retention of the concrete areas.
(v) Increasing temperature due to global warming. UNEP reports over 1.2°C rise already.
(vii) Exhaust emissions from cars — trapping heat in the cities.
(viii) Policy failure to address heat island effect.
(ix) Location of heat dome.
Rising air pushed back down.
Existing mitigation strategies:
Lumens in current strategies:
Further strategies to be adopted:
Urban heat wave mitigation require strategic and sustainable development of cities as ensured in SDG 11.
Conclusion
Urban heat wave mitigation requires strategic and sustainable development of cities as ensured in SDG 11.
