Facing Climate Change: Urban Gardening and Sustainable …

Every plant from grasses absorbs CO 2 from the air. Grass have a seasonal cycle
of fast growth periods beside flowering. But when grasses frequently mowed no
flowering can achieved. Throughout this cycle, lawn grasses continuously cover root
system and depositing carbon in the soil. After mowing grass, clippings left on the
lawn to decompose, these clippings are extra source of carbon that can be kept in the
soil below. Contrasting to gardens, which are often ploughed and ploughed, lawns
are naturally left undisturbed, allowing the soil to store carbon for long periods of
time [130]. Rates of carbon storage vary depending on the climate, soil type, and
how the grasses are managed [131].
Zirkle et al. [132, 133] calculated efficiency of lawns relating to Soil organic
carbon (SOC) sequestration for U.S. lawns. SOC was 46.0 to 1216.1 g C/m
2 /year.
They added that additional C sequestration can result from biomass gains attributable
to fertilizer and irrigation management. However, nitrous oxide emissions from lawns
have been related to the addition of nitrogen fertilizer and large watering [27].
10.4 The Role of Plants, Especially Trees, Solve Climate
Change Problems
Climate favorable landscaping is an innovative method of cultivation ornamental
plants in urban gardens in ways which reduce emissions of different types of greenhouse gases and encourage the absorption of carbon dioxide and methane by plants
in order to aid the reduction of global warming. To be a Climate favorable landscaper means considering both what happens in a garden and the materials brought into
it and the impact they have on and climate. It can also include garden features or
activities in the garden that help to reduce greenhouse gas emissions elsewhere.
Plants in forests play an important role in climate change. Afforestation or planning a forest garden can help mitigate against climate change by removing CO 2
from the atmosphere. It is stored in this “biomass” until being returned back into the
atmosphere, whether through natural processes or human interference [134].
Permaculture is most frequently applied in gardening. Urban gardening provides
habitat for wildlife, carbon sequestering, biodiversity and others. Simple urban gardening must be contained (containing or contained) three layers: trees, shrubs, and
ground plants. But for those who like to take advantage of every planting opportunity,
a deluxe urban garden can contain at least six tiers of vegetation.
As the illustration below shows, a seven-layered urban garden contains (Fig. 5):
1. Big or tall trees
2. Small or low trees
3. Hedges and shrubs
4. Bedding plants, perennial or herbs
5. Lawns or ground covers or annuals
