Facing Climate Change: Urban Gardening and Sustainable …

The use of Hedera helix climbers and Bougainvillea shrubs which find scattered
and abundant in this type of street ornamental agriculture, since they are evergreen
and are up to 6 m long, they are suitable as a climber or a shrub.
They are very sparse, and their leaves are evergreen, simple, reciprocating, oval,
full-edged, dark green. Also, Hedera helix has a good role in formaldehyde pollutant abatement. The flowers of Bougainvillea are multicolored including white, red,
purple, orange and sometimes double colors. Bougainvillea includes more than 20
varieties, and we find some varieties of hybrid that come in different sizes, and be
attractive with flowers that radiate joy and beauty. It increases its coordination value
and favors warm, humid climates, but it can withstand high temperatures and grow
under direct sunlight and withstand moisture while resisting drought.
13.1 Dodonaea viscosa
Except for Bougainvillea bush, the D. viscosa shrub can be cultivated for its low water
requirements and high transpiration rate (plants used about 2% for metabolism and
transpiration and evaporate the rest [157], beauty and their role for reducing CO 2 .
It can be cultivated in the form of shrubs and hedges that appear in their natural,
drooping and arched shape.
13.2 Schinus terebinthifolius
Brazilian pepper-tree is a shrub or small tree that reaches over 30 feet in height,
typically with a short trunk hidden in a thicket of branches. Some trees can live over
30 years. Brazilian pepper is widely grown as an ornamental plant for its foliage and
fruit.
Brazilian pepper is hard to control because it produces basal shoots if the trunk is
cut. Trees also produce abundant seeds that are dispersed by birds and ants. This same
hardiness makes the tree highly useful for reforestation in its native environment, but
enables it to become invasive outside of its natural range.
Transpiration of high amounts of water through plants contributes to the reduction
of ambient air temperatures. Its efficiency is relatively high in the absorption of CO 2 ,
making it suitable for reducing climate change.
13.3 Lantana camara
A comparative response of lantana camara and Bauhinia variegata to elevated CO 2.
Raizada et al. [158] showed that these plants are likely to emerge more competitive
in the global change scenario [159].
