What You Should Know About Vertical Farming
By 2050, the world’s population is expected to grow by another 2 billion people, and feeding it will be a huge challenge. Due to industrial development and urbanization, we are losing arable lands every day. Scientists say that the Earth has lost a third of its arable lands over the last 40 years. We don’t know how much more we are going to lose in the next 40 years. Increasing food demand due to a growing population along with ever decreasing arable lands poses one of the greatest challenges facing us.
What Is Vertical Farming?
Vertical farming is the practice of producing food on vertically inclined surfaces. Instead of farming vegetables and other foods on a single level, such as in a field or a greenhouse, this method produces foods in vertically stacked layers commonly integrated into other structures like a skyscraper, shipping container or repurposed warehouse. Using Controlled Environment Agriculture (CEA) technology, this modern idea uses indoor farming techniques. The artificial control of temperature, light, humidity, and gases makes producing foods and medicine indoor possible.
In many ways, vertical farming is similar to greenhouses where metal reflectors and artificial lighting augment natural sunlight. The primary goal of vertical farming is maximizing crops output in a limited space.
How Vertical Farming Works
There are four critical areas in understanding how vertical farming works: 1. Physical layout, 2. Lighting, 3. Growing medium, and 4. Sustainability features. Firstly, the primary goal of vertical farming is producing more foods per square meter. To accomplish this goal, crops are cultivated in stacked layers in a tower life structure. Secondly, a perfect combination of natural and artificial lights is used to maintain the perfect light level in the room. Technologies such as rotating beds are used to improve the lighting efficiency.
