is a proposed agricultural technique involving large scale agriculture in urban high-rises or "farm scrapers".
It can be used for:
Saving horizontal land
to accumulate given area for crops
Future high rise society
WHY WE NEED SKY FARMING??? Population Pressures
As Malthus identified, the human population has
a linear relationship with land
Present estimates indicated at least 80% of
potentially arable land is already being used for
About ½ of the mature tropical forest cover of the earth has been destroyed, somewhere between 750-800 million hectares.
Population and Future Predictions By 2025, the world’s population will swell from 6.6 billion to 8 billion people. Is mathematician Thomas Malthus’s 200-year-old prediction, that human growth will one day outpace agriculture, finally coming to pass Predictions and Problems:
he world’s population will live in urban areas
the total population of the world will increase by 3 billion people
to feed 3 billion more people using traditional farming techniques an estimated 10^9 hectares of new farmland must be created
Scientists are concerned that this large amount of required farmland will not be available and that severe damage to the earth will be caused by the added farmland.
Since 1970, 600,000 square kilometers of Amazonian Rainforest
have been destroyed within Brazil for agriculture uses. That is
about the size of Manitoba, or, two and half times the size of the
United Kingdom. This is approximately 40% of its size of1950
The soil of the Amazon is not ideal for crop cultivation, and tends to
only stay fertile for a limited time. Farmers are constantly clearing
more land to meet production needs
Unless significant steps are taken to limit deforestation in this area,
it is projected that by 2030 only 10% of this vital natural resource
Agriculture’s Land Consumption 26% Forrest & Savannah 38% Agriculture
Approximately 38% of the Earth’s land is being used for human agriculture. When considering all forests/wooded areas/savannahs only cover 26%, and urban space a tiny 3.5%, the scale of human agriculture comes into view.

TECHNIQUES AND DEVICES Vertical farming is dependent on various physical methods to produce food. The vertical farm brings these technologies and devices together, most of which are still under research. Some of the most common and popular technologies used are:
Solar greenhouse (technical) / Greenhouse
Aeroponics / Hydroponics
SUSTAINABILITY Methods for sky farming to make it SUSTAINABLE Environmental scientist Dickson Despommier of Columbia University and other scientists propose a radical solution:
Transplant farms into city skyscrapers
towers would use soil-free hydroponic farming to slash demand for energy
they’ll be powered by a process that converts sewage into electricity
producing more food
Free up farmland free tree would help to remove carbon from atmosphere
vertical farms would grow food near which would emission of transport
oil burned to cultivate and ship crops
most solid waste collections are simply compacted and transfer to landfills, or in a few instances, burn to generate energy.
Bring employment to a city that has a 27% unemployment rate, and also offer education for those involved.
Create a new tax base for a city that needs to collect taxes for services, but was losing more of its tax base year after year.
Bring fresh fruit and vegetables to a city where residents often have to travel twice as far to a market than to a liquor store.
Bring fresh produce to restaurants who otherwise have to buy from much farther away.
Offer a model city for other cities that also are facing declining populations and perhaps inspire other cities to bring smaller farms closer, if not within the city limits.
Create a new local economy.
Bring beauty and a natural environment to city dwellers.
Bring alternative energy to the inner city. The plan includes the installation of solar panels to power itself. Hantz Farms will also harvest wind energy and utilize geothermal heat and biomass fuel from recycling compost.
Vertical farming would reduce the need for new farmland due to overpopulation , thus saving many natural resources, currently threatened by deforestation or pollution .
Deforestation, desertification , and other consequences of agricultural encroachment on natural biomes would be avoided.
Because vertical farming lets crops be grown closer to consumers, it would substantially reduce the amount of fossil fuels currently used to transport and refrigerate farm produce.

Skyscraper vegetation is an innovative, urban agriculture technique dedicated to building sustainable, commercial-scale hydroponic farms on urban rooftops. The main goal is to improve the health and nutrition of city populations and provide new jobs and educational opportunities through the development of urban sustainable agricultural communities. Each Sky Vegetables farm will provide nutritious, chemical free and locally grown produce, while reducing environmental damage.
BENEFITS TO COMMUNITIES
Sky Vegetables provides numerous benefits to partner cities including:
