The Future of Food: Vertical Farming in Urban Spaces

By Simone de Vlaming

 

As the global population continues to rise, current food production methods will no longer be enough to meet the growing demand. Today, agriculture takes up 38% of the Earth’s land surface and is responsible for nearly 90% of global deforestation.

Unfortunately, deforestation is not the only problem with conventional food production methods. Agriculture is also linked to biodiversity loss, water pollution, excessive water use, global warming, and many other environmental issues. 

At the same time, climate change is creating unpredictable weather patterns, making it increasingly difficult for farmers to adapt and maintain consistent crop production.

Vertical farming, on the other hand, has emerged as a highly effective and environmentally friendly method for growing crops in cities. In this article, you’ll discover what vertical farming is and how it can revolutionize food production in urban areas.

What is Vertical Farming?

As the name suggests, vertical farming involves growing crops vertically. Unlike traditional horizontal agriculture, this sustainable method uses vertically stacked layers to cultivate crops one above the other. 

Another key aspect of vertical farming is that crops are grown in a fully controlled environment, where light, temperature, water, and humidity are carefully monitored. As a result, vertical farming effectively optimizes growing conditions, enabling farmers to produce more food in a significantly smaller area.

Types of Vertical Farming Systems

  • Hydroponic Vertical Farming

Hydroponic is a soilless vertical farming technique. This means that instead of being planted in soil, as traditionally done, plant roots are immersed in a nutrient solution. With this technique, farmers use a nutrient-rich water solution that provides all the essential macro and micronutrients plants need to grow healthy and strong.

  • Aeroponic Vertical Farming

Aeroponics is another vertical farming technique for growing plants without soil. But in this case, roots are suspended in the air and irrigated several times a day with a nutrient-rich mist. The main advantage of this vertical farming system is its minimal water usage.

  • Aquaponic Vertical Farming

Aquaponics is a sustainable farming method that combines aquaculture and hydroponics, cultivating both plants and aquatic animals. In this vertical system, the water where the aquatic animals live serves as a nutrient source for the plants. With this technique, farmers turn fish waste into food for plants. 

The Benefits of Vertical Farming in Urban Areas 

Space Efficiency

Vertical farming uses significantly less space than traditional agriculture to generate the same amount of food. Additionally, vertical farming can be built almost anywhere, so it does not require any arable land. Thanks to this difference, vertical farming is an effective alternative to reduce deforestation rates and prevent biodiversity loss.

Water Conservation

Globally, agriculture uses around 70% of the world’s fresh water. While conventional agriculture uses inefficient watering methods, vertical farming uses a closed system where water is always recycled and reused. This innovative system prevents water loss, ensuring plants absorb 100% of the water provided. As a result, vertical farming typically uses 98% less water than traditional agriculture. 

Lower Carbon Footprint

Traditional agriculture usually takes place far away from metropolitan areas. But since vertical farms can be constructed in urban areas, it significantly reduces the distance between the production site and the final consumer. Similarly, vertical farming gives consumers access to year-round foods without depending on out-of-season produce shipped from across the globe.

Fresh, Local Food Production

Today, more than half of the global population lives in urban areas. This number is expected to grow within the next few years, creating a higher demand for food in areas with limited space for traditional agriculture. But thanks to its space efficiency, vertical farming stands as a reliable solution to provide citizens with fresh local produce all year. 

Real-World Examples of Urban Vertical Farming Projects

Underground Growing in a Former WW2 Bunker

In south-west London, thirty-three meters below the streets of Clapham, lies the first underground vertical farm. Using hydroponic technology and green-powered LED lighting, this subterranean farm produces six times the yield of a traditional outdoor farm while using 70% less water and no pesticides.

Urban Community Farm in a Shipping Container

The University of York partnered with an indoor farming technology provider to create ‘Grow It York,’ an indoor urban community farm. This urban farm uses aeroponic vertical systems to grow fresh, pesticide-free produce in a shipping container. Community members not only benefit from the farm’s offerings but also see firsthand how their food is grown.

Seven-meter Farms in the Center of São Paulo

In São Paulo, an indoor farming company built a seven-meter-high vertical farm in response to the city’s inefficient food system. This vertical farm, developed by Pink Farms, grows a variety of vegetables, and its produce is already available in over 75 locations across the central, western, and southern zones of São Paulo.

The Future of Vertical Farming in Urban Areas

Vertical farming has the potential to replace traditional agriculture, making food production more sustainable and productive. With advancements in technology and automation, like AI-driven monitoring systems, vertical farming will be even more efficient and cost-effective in the next couple of years. 

The biggest advantage of vertical farming is that it can turn unused urban spaces —such as rooftops, containers, or vacant buildings— into food-producing areas. As the global population grows, vertical farming will become the most effective and sustainable solution for bringing foods closer to consumers and meeting increasing food demand in urban areas. 

Moreover, this sustainable farming method can create new job opportunities, reduce deforestation rates, prevent biodiversity loss, conserve water, prevent water pollution, and promote sustainable living practices.
