Abstract
Deteriorating quality of urban ecosystems is a major concern of urban planners and managers. Environmental problems such as air and water stress and pollution are more rampant in urban areas which currently account for 78 per cent of global carbon emissions, 60 per cent of water going for domestic use (Shivanand et al. 2010). It is therefore essential to take steps to redesign the urban ecosystems to address these environmental problems and to sustain clean air, water and other ecosystem services needed for healthy urban living. In the urbanization process built up areas replace the vegetation cover and also increase in vehicle movement. These activities are likely to increase the release of pollutants and greenhouse gases resulting in increased atmospheric temperature, decreased air quality and increased levels of stress for trees (Saini, 2017). Trees act as major CO2 sink which captures carbon from the atmosphere and stores the same in the form of biomass in the growth process while releasing oxygen to the air through photosynthesis (Watson et al. 2000). Conservation and restoration of urban green spaces comprising of “urban trees” is therefore an important approach to improve the environmental quality of urban areas.
