Vertical farming is the practice of growing produce in vertically stacked layers. Vertical farms come in different shapes and sizes, from simple two-level or wall-mounted systems to large warehouses several stories tall. Vertical farming typically uses a mix of natural light and artificial light. Artificial lighting is often LED-based and may be driven by a renewable power source such as solar power or wind turbines.

4. Introduction
Vertical farming is the practice of growing produce in vertically stacked layers.
Vertical farms come in different shapes and sizes, from simple two-level or wall-mounte
systems to large warehouses several stories tall.
Vertical farming typically uses a mix of natural light and artificial light. Artificial
lighting is often LED-based and may be driven by a renewable power source such
as solar power or wind turbines.

5. What is Vertical
Farming ?● Changing the way of farming from horizontal to vertical.
● New agricultural technique in order to maximizing the use of the land.
● These farms will be developed in major urban centers as a farm shopping
centre concept.
● Concern about the environmental, recycling waste and farming system.
● Vertical farming could provide year round food production and better crop
production

● Agricultural products are exposed to
pesticides
● Increased and Year-round Crop
Production
● Water containing pesticides and fertilizer
wastes are not controlled
● Protection from Weather-related
Problems
Why Grow Vertically?
● Lack of land space

9. Environmental Impact
Water
70% of our freshwater supply goes to agriculture. 70% of water contamination comes from
agriculture.
Land
25% of the world’s land is now highly degraded, with soil erosion, water degradation and
biodiversity loss.
Carbon Emissions
from drilling for water, pumping from deeper reserves than ever before, operating tractors,
and harvesters, traditional commercial farming is quite energy intensive. vertical reduces h
transportation emissions by 98% on average. 9

10. Types of vertical farms
Hydroponics:
• Hydroponics involves growing plants in
nutrient solutions that are free of soil.
• The plant roots are submerged in the
nutrient solution, which is frequently
monitored and circulated to ensure
that the correct chemical composition is
maintained.

11. Aeroponics:
• The National Aeronautical and Space
Administration (NASA) is responsible
for developing this innovative indoor
growing technique. In the 1990s, NASA was
interested in finding efficient ways to grow
plants in space.
• Growing plants in an air/mist environment with
no soil and very little water.

12. Aquaponic:
• An aquaponic system takes the hydroponic
system one step further, combining plants
and fish in the same ecosystem.
• Fish are grown in indoor ponds, producing
nutrient-rich waste that is used as a feed
source for the plants in the vertical farm.
• The plants, in turn, filter and purify the
wastewater, which is recycled to the fish
ponds.

13. CEA- controlled-environment agriculture
• Temperature (air, nutrient solution, root zone , leaf)
• Humidity : 40-60%
• Co2 level
• Light ( intensity, Duration)
• Nutrient concentration
• Nutrient PH: 6-7.5
• pests

22. The Future…
Vertical Hydroponic Farming
It is estimated that by 2050 the
world’s population will have
boomed to 9.1 billion people.
According to the UN food
production will need to increase
by 70%.
A pioneer in this field of
sustainability, Dickenson
Despommier, a micro-biologist
and ecologist at Columbia
University’s School of Public
Health, sees vertical farming as
the answer to this problem.

23. Conclusion
• Vertical farms in urban areas are a relatively new phenomenon,
but interest in this approach is growing, and the number of
vertical farms in the United States is expanding every year.
There are several variations of vertical farms being tested
throughout the world, and new innovations and technology will
likely increase the energy efficiency and profit margins of these
farms in the future.
In the near term, most vertical farms will focus on high-return
and short-rotation crops such as salad greens, with nearby
restaurants often buying all of the production. 23
