This is a topic of lively debate between researchers and environmental scientists, with industry perspectives and case studies to provide a comprehensive understanding of its implications and potential. 

Industry Perspectives on Vertical Farming

In Forbes’ article “Supermarkets and Shoppers Must Embrace Vertical Farming, Our Future Depends On It,” Vonnie Estes and Phil Lempert offer industry perspectives on the challenges and opportunities of vertical farming. 

Estes, the Vice President of the International Fresh Produce Association, wrote in the article about the need for collaboration between vertical farms and traditional agriculture. Estes highlights the importance of bridging the gap between different farming methods, articulating that, “the vertical farming industry does have a lot of promise and opportunity because grocery retailers want this product, want a surety of supply, want consistency of quality”, which underscores the growing demand for vertical farming products within the industry. Vonnie Estes emphasizes the importance of collaboration between vertical farms and traditional agriculture to address common goals and challenges. One example of successful collaboration is the partnership between AeroFarms, a leading vertical farming company, and the New Jersey Agricultural Experiment Station (NJAES). AeroFarms collaborated with NJAES to research and develop new varieties of leafy greens optimized for vertical farming environments. This collaboration not only improved crop yields and quality but also helped both the vertical farming experts and traditional agricultural researchers to understand each field and their respective pros and cons. 

On the other hand, Lempert, one of America’s leading food and consumer trend-watchers and analysts, analyzes the role of vertical farming in overcoming the impacts of climate change on food security. He explains vertical farming as a revolutionary solution tailored to the needs of an increasingly urbanized world such as ours. Lempert states that “Vertical farming has become a revolutionary solution to the growing challenges of traditional agriculture in a world where climate change is raging havoc over growing our foods”, highlighting the urgency of embracing solutions like vertical farming to adapt to changing environmental conditions and ensure food security for future generations. Integration of vertical farming into urban resilience strategies is one example where vertical farming has demonstrated its potential. For instance, in cities prone to extreme weather events like hurricanes or droughts, vertical farms are resilient food production systems less susceptible to climate-related issues. Initiating vertical farming in regions experiencing water scarcity due to climate change is another example where vertical farming has demonstrated its potential. Vertical farming systems, such as hydroponics or aeroponics, use significantly less water compared to traditional soil-based agriculture. Regions like the Middle East have established vertical farms powered by desalinated seawater to produce fresh produce sustainably despite limited freshwater resources.

Recognizing the importance of teamwork and fresh ideas, professionals in the industry like Estes and Lempert are clearing the path for more people to embrace vertical farming. As this method gains popularity in the fight against global food shortages, it’s crucial to listen to the advice of those who know the industry best.

With long-term agricultural practices, compounded by pollution, contributing significantly to the depletion of natural resources, the need for advanced technologies in agriculture increases more day by day. The case study about the future of technology and food systems underscores the pressing challenges posed by resource scarcity, particularly in urban environments like Singapore. Traditional agricultural methods have historically strained land and water resources while intensifying issues such as land degradation and water scarcity. In response, Singapore has utilized hydroponics and aeroponics to mitigate these challenges. By reducing reliance on conventional farming practices that deplete soil fertility and consume excessive water, vertical farming offers a sustainable alternative to the traditional agriculture many nations continue to practice today. With the technology of vertical farming in our grasp, we can collectively “overcome the limitations imposed by conventional agriculture, thereby enhancing food security and environmental sustainability in resource-scarce urban settings”, according to the case study in Singapore. Additionally, the adoption of vertical farming technologies minimizes pollution risks associated with chemical fertilizers and pesticides, preserving water quality and supporting ecosystem health. 

Scholarly Perspectives on Vertical Farming

Vertical farming offers innovative solutions to address pressing global challenges such as food insecurity, environmental degradation, and urbanization. Besthorn is currently a professor at the school of social work  at Wichita State University and has various publications in the realm of social work and sustainable social action. Besthorn contextualizes vertical farming within broader discussions of environmental sustainability and social justice while underscoring the importance of collaboration in addressing societal challenges. He emphasizes the evolving nature of social work, stating, “Social work has never been singularly involved simply in the assessment, intervention, and treatment of individual psychological conditions.” This highlights the role of social work in initiatives like vertical farming therefore addressing systemic issues such as food insecurity and environmental degradation.

Similarly, Sanjuan-Delmás, a researcher and project manager with a masters in Environmental Studies with a specialization in Industrial Ecology, and his team of researchers’ study on the environmental assessment of integrated rooftop greenhouses (i-RTGs) underscores the innovative nature of vertical farming systems.
