Population
Growth
By the year 2050, 80% of the world population will be living
in city and urban communities.In 1990, less than 40% of the world’s population lived in a
city.

Solutions?Use Urban Farming
Technologies to Supplement Traditional Farming –
Agricultural Revolution• Hydroponics• Vertical Farming• Aquaponics
Hydroponics
Hydro = water Ponos = labor “Working Water”
Hydroponics at Home
Modern Hydroponics
Hyundai’s Nano Garden• Light, water, and nutrient supply controllable so users decide growth speed.• Functions as an air purifier, eliminating unpleasant smells
Kitchen CultivatorHydroponics built into kitchen island on wheels
Rotary Hydroponics
The Green Wheel developed by NASA
Manage the amount of light, control the temperature, and check the water level with a smart phone!
Rotary Volksgarden
• designed to hold 3" root medium
• accommodates space for up to 80 plants.
• chain driven and rotates a constant 24 hours a day
• watering and light timers
• cost is $2595
Hydroponics Technology
Hydroponic Accessories:• Testers for pH, PPM, EC,• Meters for temperature and
humidity• Meter calibrators• Lighting system• Nutrients - Grow formula, Bloom
formula, Supplements, Ph• Pumps, air stones
Rooftop HydroponicsGotham Greens Rooftop Farm located in
Brooklyn, New York
• 15k square feet• 100 tons of produce in the first year• $2 million dollar start-up• Yields 20% more than traditional
farming
Rooftop Hydroponics
Vertical Farming
• The practice of growing in a vertical direction
• Usually without soil (hydroponically)
• Usually in urban areas, and sometimes as high as skyscrapers
• May include livestock
Vertical Gardens
Vertical FarmsVertical HarvestJackson Hole, Wyoming
Opening early 2016
• Three-story, 13,500 square-foot hydroponic green house (150’ x 30’)
• Should produce over 37,000 pounds of greens, 4,400 pounds of herbs, and 44,000 pounds of tomatoes
• 95% of future crops already sold to local restaurants, grocery stores, and a hospital
• Employs citizens with disabilities

Vertical FarmsSky Greens Vertical
FarmSingapore
• World’s first low carbon, hydraulic driven vertical farm
• Uses minimal land, water and energy resources
• 10x more productive than conventional farming
• Only $360/month ($3/tower) on electricity
• 3 stories tall, 120 aluminum towers
• Able to produce 1 ton of fresh veggies every other day
The Future of Vertical Farms
Floating Farms F.R.A.
(Floating Response Architecture)
Proposal for SingaporeBy JAPA Design Firm
• Loop shape enables the vertical structure to receive more sunlight without having significant shadows
• System will aim for zero food waste by using a data management system to track of how much food people are buying, so the farm can automatically adjust production
The Future of Vertical Farms
• 132 Stories of urban farming with room for cattle, poultry, and 28 different types of crops
• Utopian superstructure of offices, research labs, housing, and communal areas, orchards, farms, and production rooms
• Dragonfly has steel and glass set of wings so as to maintain proper soil nutrient levels and reuse of bio-waste

Aquaponics• System of aquaculture
in which the waste produced by farmed fish supplies nutrients for plants grown hydroponically, which in turn purify the water.
• Aztec Indians grew vegetables on floating rafts around 1000 A.D.
• Gaining more use, research, and development in the past 35 years
Aquaponics
Generally, a well-managed system with a 300 gallon fish tank will produce:• 10 pounds of vegetables per every square foot of
grow space• 50 to 80 pounds of fish per year
Aquaponics at Home

Larger Aquaponics Systems
Shipping crate that has been modified to be an aquaponics garden; the crate houses the fish, the fish provide nutrients that feed the plants above.

technology
Commercial Aquaponics
FarmedHere – Chicago, Illinois• 90,000 square feet of a formerly abandoned suburban Chicago
warehouse, actually equals 140,000 square feet of growing space. • Energy-efficient compact-fluorescent lights; even though the lights run
continuously, they only account for 18% of the facility's overall costs.• Aquaponic growing technologies save up to 97% of fresh water. • Produces organic food an average of two- to three-times faster than
traditional farming methods.
Commercial Aquaponics
The Plant – Chicago, Illinois• 93,000 square foot building • Dedicated to developing circular economies of food production,
energy conservation and material re-use• Vertical urban farm that combines aquaponics with kombucha
tea production, beer brewing, biogas energy, and a kitchen that serves up the end result with net-zero waste
• Diverts 10,000 tons of waste per year
Drawback to these types of Urban
Farming?Not all Crops are Sustainable in Hydroponics
Sensitive Ecosystem, Knowledge/Education Required for Crop Success
Expensive Start-up
Cost of Energy (Getting better with technological advances)
There are too many benefits from a rural farm, such as mass production of wheat, corn, soybeans, cotton, and feed
crops.
These farming methods are not meant to entirely replace traditional
farming.
Urban Farming can help solve the Earth’s
food crisis!Vertical Farming

ponics
Aqua-ponics
• Preserve the Environment
• Reduce the Carbon Footprint
• Year-round Higher Yield Crops
• No Weeding and Waist-High Harvesting
• No GMOs, pesticides, or herbicides
• Reduce Food Waste
• Use 95% Less Water
• Grow in any Environment
• No Agricultural Runoff/Toxic Fertilizers
“The questions arises, can we supply enough food for everybody on the planet, including a growing urban
population? and I think we can. And I think we can do it by empowering people in the cities to grow food
right there,” – Dickson Despommier, Columbia University.
“Modern agriculture is the largest consumer of land on the planet, it’s the largest consumer of fresh water on
the planet, about 60% of the world’s fresh water withdrawal goes toward conventional agriculture; it’s the source of the world’s most water pollution, it is responsible for about 15%of the global greenhouse
emissions.” Viraj Puri
