As the twenty-first century has been deemed by the UN as the century of the megacity with predictions that nearly 75% (?) of the population of the world will live in cities by the end of the century, urban areas will increasingly need to be planned and developed to take into consideration the ecological and environmental health of the urban climate to ensure cities can cater for people. This is also a pressing matter in as it is recognized that there is a need to adapt cities to the negative effects of climate change. These issues have been central to the work of...
