Vertical farming has been deemed a viable and essential solution to the current supply chain disruptions and growing population. Conventional farming methods are facing immense pressure due to limited land availability, water scarcity, and the adverse effects of climate change. Vertical farming is designed to increase space utilisation, optimise resource efficiency, and minimise environmental impact.
In this blog, we will be exploring the concept of vertical farming in detail.
Vertical Farming: A Game-Changing Solution
An innovative approach to agriculture, the concept of vertical farming involved cultivating crops in vertically stacked layers or vertically inclined surfaces. Unlike conventional farming which relies on vast expanses of land, vertical farming utilises multi-storey buildings, skyscrapers, and specially designed structures that are well-equipped with artificial lighting, climate control systems, and hydroponic or aeroponic cultivation methods. Vertical farming facilitates year-round production of a variety of crops in controlled environments, without getting influenced by external factors.
Vertical Farming: Evolution
The concept of vertical farming reportedly can be traced back to the Hanging Gardens of Babylon. But, with technological advancements and the pivotal need for sustainable food production, modern-day vertical farming evolved significantly. The introduction of hydroponics in the 20th century revolutionised indoor cultivation, allowing plants to grow in nutrient-rich water instead of soil. With this, the concept of vertical farming evolved as we know it today.
The remarkable progress in modern-day vertical farming is driven by advancements in lighting systems, automation, and data analytics. Traditional fluorescent lighting got replaced by energy-efficient LED lights, enabling precise control over the light spectrum and intensity to optimise plant growth. Automation technologies like robotic seeding, harvesting, and monitoring systems have enhanced operational efficiency and minimised labour requirements. Additionally, integrating AI and machine learning helps vertical farms to collect and analyse real-time data, facilitating predictive analytics for optimised crop growth.
The Need for Vertical Farming
- Land Scarcity and Urbanisation: The global population is expected to reach 9.7 billion by 2050, and with this land scarcity has become a concerning issue. Vertical farming is a practical solution to produce food in urban areas with a space crunch. It is done by using vertical space in buildings, abandoned warehouses, and underground tunnels. Since it is done in close proximity to urban centres, the need for long-distance transportation is minimised.
- Reduced Efficiency: For traditional agriculture, there’s a requirement for vast amounts of land, water, and energy. Vertical farming addresses these inefficiencies by using a fraction of the land required for traditional farming. By implementing hydroponics or aeroponics, vertical farming can minimise water usage compared to traditional soil-based cultivation. Additionally, the controlled environment in vertical farms allows for precise temperature-control, humidity, and nutrient-delivery, optimising resource utilisation and minimising waste.
- Climate Resilience: One of the major challenges impacting traditional agriculture is climatic changes such as extreme weather events, water scarcity, and increasing temperatures affecting crop yields. Through vertical farming, farmers can get a climate-controlled environment, protecting crops from adverse weather conditions, pests, and diseases. Since all these external factors are eliminated with vertical farming, the farms offer a resilient solution, ensuring consistent production, irrespective of the season or geographical location.
- Fresh and Local Produce: Vertical farms can supply fresh produce throughout the year, even in regions with harsh climatic conditions or limited agricultural potential. Minimising the time and distance between harvest and consumption, vertical farmers ensure the delivery of nutritious and flavoured produce. Additionally, local vertical farmers support the growth of urban agriculture that favours community engagement and minimises the carbon footprint associated with long-distance transportation.
- Environmental Sustainability: Conventional agricultural practices lead to environmental degradation like deforestation, soil erosion, and water pollution. Vertical farming offers a sustainable alternative by minimising the negative impacts of agriculture on the environment. Since vertical farms use a fraction of the land that conventional farming requires, the chances of deforestation get reduced, preserving natural habitats. Also, since vertical farming is all about soil-less cultivation techniques like hydroponics and aeroponics, the scope of soil erosion and nutrient runoff gets eliminated. At the same time, vertical farming integrates sustainable farming practices like water recycling, renewable energy sources, and organic pest management that in turn reduce their ecological footprint.
- Food Security and Self-Reliance: Since vertical farming involves producing food locally throughout the year, the dependency on long-distance transportation and imports gets reduced. This resilience is crucial during a crisis like natural disasters or pandemics when the supply chain gets disrupted. Through vertical farming, communities are empowered to hold better control over their production of food, ensuring a reliable supply of fresh produce.
- Technological Innovation and Economic Opportunities: Vertical farming involves technological innovations that open up new economic opportunities. With the advancement in the industry, research and development efforts are focused on improving automation, energy efficiency, and crop optimisation. This innovation creates a requirement for skilled professionals in agritech, robotics, data analytics, and sustainable engineering. Additionally, vertical farming can lead to economic growth by revitalising urban areas, repurposing unused buildings, and bringing in investments in the agricultural sector.
Vertical farming is a revolutionary approach to agriculture that addresses issues such as land scarcity, resource inefficiency, climate resilience, and environmental sustainability.
