Modern urban areas have typically darker surfaces and less vegetation than their surroundings.
These differences affect climate, energy use, and habitability of cities. We estimated the effect of
temperature, intensity of solar radiation, relative humidity and wind speed to change local microclimate of
IARI campus. We used GIS-based method for locating potential tree-planting and sites modification based
on land cover data. One of the key tasks of planners is how to optimize the benefits of urban green spaces. In
Arc-GIS environment, digital maps of different features/objects such as roads, buildings, green spaces and
trees were prepared and classified. Geo-coordinates (latitude & longitude) of the trees were measured with a
GPS receiver. The GPS points were added to an existing Arc-GIS map of campus. Tree species in the
campus were catalogued with different attributes. A comprehensive study of 50 tree species were made out
of the large number of genera and various species (approximately 3700) across the I.A.R.I. Campus. Urban
greening had been proposed as one approach to mitigate the human health consequences of increased
temperatures resulting from climate change. Systematic review methodology to evaluate available evidence
on whether greening interventions, such as tree planting in a campus affect the air temperature of an urban
area. Most studies conducted abroad revealed that the air temperature reduced beneath the trees and were
broadly supportive that green sites could be cooler than non-green sites. It was felt that the temperature of
IARI campus with dense tree plantation was cooler than of outside. A systematic microclimatic study was
done with five selective tree species namely, Ficus religiosa, Azadirecta indica, Alstonia scholaris, Ficus
infectoria and Morus alba during peak summer (May-June-July, 2010) and peak winter (December-January,
2010-11) seasons at IARI Campus, New Delhi, India. Solar radiation intensity, temperature, relative
humidity and wind speed beneath the selected species and in the open space were recorded. Tree species
were examined for their efficiency to provide improved micro-environment for living and working in the
IARI campus with the help of above mentioned parameters. It was found that Ficus infectoria in summer
and Morus alba in winter were most efficient to modify micro-environment for betterment. Ficus infectoria
reduced the average summer noon temperature beneath the canopy by 3o
C and by 5.6o
C on an extremely
hot summer noon. Morus alba increased the winter morning temperature by 0.8o
C. Over all, Morus alba
was found to be the best species for both summer and winter. In the light of present study, some
modification in tree plantation and substitution has been suggested through GIS map which would be able to
provide better micro-environment in the IARI campus. This type of GIS based and micrometeorological
study will be helpful to establish a new institutional campus. Further research, in this aspect, is necessary for
all other Ornamental tree species in order to efficiently guide the design and planning of urban green space,
and specifically to investigate the importance of the abundance, distribution and type of greening. Any urban
greening programme implemented would need to be appropriately designed and monitored to continue to
evaluate benefit to human health.
