Vertical Farming By Sam Keegan
2
Background Human overpopulation = Over 9 Billion by 2050
Rapid Urbanization 10,000 years ago, move from hunting and gathering to agriculture Green Revolution 1960’s Technological advancements Mass agricultural production
3
Problems with Traditional Agriculture
Solution to increase food production to cater to the growing population: Expansion and Intensification Expansion: Intensification: land degradation destruction of natural habitats deforestation genetically modified crops increasing irrigation increasing fertilization
4
Problems with Putting Traditional Farms in Urban Areas
Obstacles Difficulty acquiring large amounts of land Insecurity of land tenure Difficulty installing proper farming infrastructure such as hoop houses, storage sheds, and irrigation systems Difficulty finding enough sunlight/quality soil in urban areas
5
Vertical Agriculture; The cultivation of crops using hydroponic and aeroponic technologies, organized in vertically stacked layers such as a skyscraper or multiple story building.
6
Hydroponics
7
Aeroponics
8
Environmental Benefits
Irrigation Systems -uses 8% of the water used on conventional farms -water is recycled in vertical farms -potential to use municipal waste water
9
Environmental Benefits
(2) Renewable Energy -Photovoltaic cells on roof and surrounding buildings -Geothermal Energy -Wind Energy -Incinerated Waste (Plant and Human)
10
Environmental Benefits
(3) Reduce Pollution -Fertilizers would remain inside the building -Prevents water pollution of pesticides, herbicides, and silt -Reduces amount of CO2 and Nitrous Oxide in the atmosphere (4) Bioremediation -By moving agriculture from the country and into the city, abandoned farmland could be preserved and left untouched in hopes of restoring biodiversity -Could aid in the effort to slow down climate change
11
Environmental Benefits
(5) Increased Production -Year-round farming allows for maximum production -Controlled environment eliminates factors such as unpredictable weather, pests, weeds, and diseases (6) Food Sovereignty -Vertical Farms tend to the demands of the surrounding population rather than the demand of the market -More sustainable because there is less overproduction of goods, therefore lessoning the disposal of unused produce
12
Why No Large Scale Farms?
Obstacles: -Lack of experienced farmers familiar with this technology -Economic viability of providing enough water and energy to a large scale farm - “Food from Chemicals” -Requires a collective effort of indoor agronomists, businessmen, engineers, architects, politicians, ect.
