Looking at the past and current state of agriculture, we have come to the conclusion that it is failing to provide nutritious foods, it is insufficient to sustain us in the future and the ecological destruction caused my modern farming methods has taken an incredible toll on our planet.
Dr. Despommier's solution is to utilize skyscrapers to grow food hydroponically in the middle of cities. According to Dr. Despommier, the vertical farm has a number of advantages over traditional agricultural methods used currently worldwide.
1. Year-round crop production. By growing crops inside controlled environments, crop production is not dependent upon the seasons. Instead of one season of tomatoes, staggered planted tomatoes can be harvested year round.
2. No Weather-related Crop Failures. By growing foods in controlled environments; droughts, floods, hurricanes, tornadoes and other natural phenomena are irrelevant.
3. New Employment Opportunities. When farming exists in a skyscraper there are plenty of job opportunities created in the cities. In the Vertical Farm, the crops exist in all of these stages all the time, necessitating the need for labour.
4. No Agricultural Runoff. "According to the USDA, Agricultural nonpoint source pollution is the primary cause of pollution in the U.S." - The Vertical Farm. By growing hydroponically in a controlled environment, these toxic chemicals are essentially unnecessary.
5. Allowance for Ecosystem Restoration. By moving agriculture into city skyscrapers, Dr. Despommier argues traditional agriculture won't be necessary and the land can be turned back over to nature for recovery.
6. Animal Feed from Post-harvest Plant Material. You don't eat all parts of a plant and what is leftover can be used as animal feed.
7. No Use of Pesticides, Herbicides, or Fertilizers. Guess what? There are no weeds to pull in hydroponic/aeroponic/aquaponic systems! So there's no water pollution caused by this method of farming.
8. Use of 70-95 percent less water. According to The Vertical Farm, "Today, traditional agriculture uses around 70 percent of all the available freshwater on earth, and in doing so pollutes it." Of all the benefits on this list, this is the most important of them all.
9. Purification of Grey Water to Drinking Water. Grey water reclamation will become an even hotter topic as the scarcity of clean water becomes more desperate. Plants provide a natural (bio) filtration process that can cleans the water.
10. Greatly reduced food miles. A common argument for alternative farming is that the average distance food travels from farm to table is 1500 miles, on average. The Vertical Farm proposes growing food in the centre of cities, drastically cutting this distance down.
11. More Control of Food Safety and Security. The Vertical Farm is designed using the same equipment hospitals use in intensive care units to prevent pathogens and pests from affecting the crops. Security is proposed to prevent people from sabotaging the environment produced.
