Vertical farming is the practice of growing crops in vertically stacked layers utilizing modular, high-rise or retrofitted buildings. The system integrates indoor farming methods and advanced Controlled Environment Agriculture (CEA) technologies, which allow intelligent monitoring and robust control of the growing environment. Therefore, maintaining favourable climate conditions (humidity, temperature, airquality and composition, airflow, light spectrum and etc.) foroptimal growth and development of cultivated life forms.
In 2021, the global population surpassed 7.8 billion people. The expected human population of 9.7 billion by 2050 will demand a 70% increase in food production. Meeting global food security demands on finite global land would require an exponential increase in land-use efficiency. With 55% of the world's population living in urban areas, there is a need for sustainable urban food production. In fact, within the next 20 years, as many as 80 % of us will live in or very near a city, making urban agriculture even more relevant a practice.
Tomorrow's agriculture could be significantly impacted by fast-paced climate change over the next five decades. It is estimated for every 1 degree of increase in atmospheric temperature, 10 % of the land where we now grow food crops will be lost. Ensuring stable food supplies during an era of rapid population growth and climate change is a challenge that will require multiple solutions.
Vertical farming is one of the robust solutions to global food security challenges. Controlled Environment Agriculture technologies are well-established and guarantee a safer, more reliable food supply that can be produced year-round, located close to urban centers. Vertical farming systems allow production schedules to synchronize to the timing of typical consumer demand patterns rather than to favorable weather patterns, which may also reduce waste through closer alignment of the timing of the demand and supply of perishable produce.
Creating sustainable food-generating systems within urban landscape would be of paramount importance to alleviate major environmental damages caused by anthropogenic activities. Integrating highly technological food production systems into urban landscape may reduce the disturbance of energy flows within natural ecosystems enabling them to renew themselves.
