This document discusses the benefits of the horticulture industry and green infrastructure for the environment. It notes that horticulture addresses plant production and landscaping, which can improve air and water quality, reduce carbon footprints, prevent soil erosion, and manage stormwater runoff. Green roofs and urban forests are highlighted as green infrastructure that retains rainfall, filters pollutants, provides wildlife habitat, and regulates urban heat islands. Constructed wetlands are also discussed as a way to treat wastewater and store water in urban areas. The document recommends greater emphasis on protecting and enhancing urban green spaces for environmental and social benefits.

production of plant materials to
enhance populated areas

Horticulture Industry can play a part in changing climate
Climate Change

Wild landscapes are decreasing with growing human population
Inappropriate urban planning policies

6. Green Roof
• A layer of vegetation planted over a waterproofing
system that is installed on top of a flat or
slightly–sloped roof
• Also known as vegetative or eco–roofs
• Green roof growing medium is composed of mineral
aggregates and only a small amount of organic
material
• It should have good consistent drainage and aeration
with a structure that enables it to hold water

8. Benefits of Green Roof
• Reduce annual storm water run-off by 50-60% on
average, including peak runoff
• filter air pollutants, nitrogen oxide (NOX ), sulfur
dioxide (SO2 ), carbon monoxide (CO), and ground-le
vel ozone (O3 )
• a 1,000-square foot green roof can remove about 40
pounds of PM from the air annually while also
producing oxygen and removing carbon dioxide (CO2
• the inclusion of green roofs in a city landscape has
been shown to reduce noise pollution by 2 – 8
decibels.

11. Wet lands
• A constructed wetland is an artificial wetl
and to treat sewage, grey water, storm wa
ter runoff or industrial wastewater.
• They are created for Urban area water
management

14. Urban Landscape
Urban landscape programs establish trees in
public spaces such as parks, along streets
and alleys, or in any available open areas
that local governments manage

17. Benefits of Urban Landscape
• Trees can reduce runoff in urban areas by up to
17%
• A 2006 study estimated that urban trees in the
United States remove 784,000 tons of pollutant (
PM, NO2 , SO2 and CO) per year
• key component in conservation of pollinators un
der pressure of reduced natural habitat

18. Urban Landscape Improves Hydrological Cycle
A grey cemented city merged with urban landscapes and tress can enhances the
hydrological cycle in Landscapes

20. Recommendation
We should all place greater emphasis on
protecting and enhancing gardens
and green space in our cities for the
benefit of the environment and future
generations.
