Human invention from Nature’s creation - the Vertical Garden

     November 2016, location Delhi, after heavy smog condition which prevailed for 5-6 days in the city, it was considered to be an alert alarming bell. Problems caused by ignorance, unresponsiveness by the people and administration resulted in polluted air and polluted environment of the city. It’s high time that people should step up along the way towards reducing pollution level. According to World Health Organisation WHO’s last year report half of the world’s 20 most populated cities are in India. People should turn to become more responsible, more nature lover, more Eco-friendly. Nature can destroy and its nature only which can save from destruction. The only solution to problem of pollution, climate change and global warming is, to plant more and more trees. Planting trees and saving trees has become a big task especially in metro cities. Big trees and plants can’t be grown on city paths, streets, flyovers etc. As a result we can only see concrete jungle everywhere.
     Nature lovers still come out with an idea of having vertical garden. Due to reduction in land spaces in the city, vertical garden can be a very intelligent step. We all have studied different types of plants in our junior classes, we know about climbing plants such as money plant. Also we have seen plants growing on mountain rocks, between pebbles. So we can say that these vertical garden is no new concept, it’s already a nature’s gift just we have to do justice with it. Apart from climbing plants like money plant, grapevines, cucumber etc there are several other plants which come in the category of vertical garden. These may or may not be climbers.
    Mr. Patrick Blanc, a botanist by profession is believed to be inventor of the vertical garden, while some say it was professor Stanley Hart who invented this concept. Blanc’s first working project was in 1988 at the museum of science and industry in Paris.
     Vertical garden system allows growing flowers, vegetables, herbs and plants on vertical elevation. It is very useful when ground space or horizontal space is limited. These vertical systems comes in various forms, it can be 2 or 3 tier metallic stands, hung on railings or mounted on walls.

     In these gardens different modular panels are fitted which comprises of irrigation system, a medium for growing and plants. Such system is very useful especially in cities, which has less landscape area for planting. Some of the benefits of vertical gardening are:
  1. Covers up dirty walls and gives a beautiful view.
  2. These plant arrangement and soil have a sound absorption feature, which helps in decreasing voice level.
  3. During rainy season outdoor vertical gardens absorbs water thus help in conserving rain water.
  4. Reduces CO2 level and increases O2 level (normal characteristic of plant), thus help in reducing global warming.
  5. It helps in keeping the room temperature moderate according to the season, thus act as insulation for the building.
  6. Plants purify air thus improves air quality of the building.
  7. Gives healthy habitat to butterflies, birds and insects.
  8. Gives a strong message to society, of being a green building, going eco-friendly.
     Plants which are grown in vertical gardens are: one of the most popular climbers which is known as money plant. Apart from money plant there are several other plants which can be used in indoor and outdoor gardens which includes wedding vine, peace lilies, wax flower, fern etc. Vegetables and spices like tomato, cloves, tulsi, aloevera, cardamom etc. which grow in less space can also be planted.

     Some of the projects of vertical garden are:
Buildings and houses in Delhi are having vertical garden system. Our Environment Ministry building (when seen from inside) have climbers spread all over the building. Some of the streets in Delhi have these vertical metallic panels erected by the side of the road having plants in it. Bengaluru also gets its first vertical garden erected under a flyover.  This step has been taken to curb the pollution level in Bengaluru. This garden has 3500 saplings of 10 different species been planted, having an automated drip irrigation system.  Asia’s very first vertical forest is being built in China’s concrete forest. Nanjing towers will plant 3000 plants comprising trees and shrubs.  This garden will produce nearly 60kg oxygen every day.

     Nature has given it’s best to us, human being should act responsibly, we should preserve, conserve and grow more and more trees thus helping in controlling some percentage of pollution in cities.
