Introduction

Urbanization is the process by which large numbers of people become permanently concentrated in relatively small areas, forming cities. Urbanization in India has witnessed a significant rise. According to the World Bank, India’s urban population increased from 17.9% in 1950 to 34% in 2020, and it is projected to reach 50% by 2050.

Urban farming is the practice of growing crops, raising livestock, or cultivating fish within urban areas like cities and towns. Example- Backyard gardens in urban homes.

Vertical farming involves the cultivation of crops in vertically stacked layers or vertically inclined structures, maximizing the use of vertical space. Vertical farming has been given many different definitions depending on the size, density, amount of control, layout, building type, location, and purpose of use. Example-Sky Greens, Singapore.

Urban and vertical farming methods have demonstrated effectiveness in addressing the challenges posed by a growing population as follows:

• Efficient Land Utilization: Urban and vertical farming maximize the use of limited land resources in densely populated areas. By utilizing rooftops, balconies, indoor spaces, and vertical structures, these methods enable food production in urban environments without the need for extensive land expansion. Example- In Japan, where land is scarce, vertical farming has been explored as a solution ie Mirai farming.
• Increased Food Production: Urban and vertical farming methods allow for higher crop yields per square meter compared to traditional farming practices. By utilizing advanced technologies like hydroponics or aeroponics. Example- Ikea’s “Lokal” Collection, Taiwanwhich includes hydroponic cultivation kits designed for urban homes.
• Localized Food Supply: Urban and vertical farming facilitate localized food production, bringing agricultural activities closer to urban consumers. This reduces the reliance on long-distance transportation and the associated carbon emissions. Moreover, it enables the availability of fresh and nutritious produce in urban areas, contributing to improved food access and security. Example- Green Sense Farms, USA.
• Reduced Environmental Impact: These methods prioritize sustainability by minimizing the use of pesticides, fertilizers, and water resources compared to conventional farming. Urban and vertical farming also reduce land degradation and the conversion of natural habitats, preserving ecosystems and biodiversity.
• Job Creation and Economic Opportunities: Urban and vertical farming initiatives can generate employment opportunities, especially in urban areas. From farm management to technology development and maintenance, these methods require a skilled workforce. Additionally, the growth of urban farming can stimulate local economies through the establishment of agri- businesses and value-added food processing industries. Example- Infarm, Germany, it designs modular indoor farms that can be placed in grocery stores, restaurants, and other urban locations.
• Community Engagement and Education: Urban and vertical farming initiatives promote community engagement and education on sustainable food production practices.
• Reduced occupational risk : Vertical farming is people-friendly. Some hazards that can be avoided in vertical farming are accidents while operating heavy farming equipment and exposure to harmful chemicals

Challenges:

• Land Scarcity and Cost: Land availability and affordability can be significant barriers in densely populated urban areas.
• Access to Capital: Securing funding and investment for these projects can be challenging, especially for small-scale farmers or entrepreneurs.
• Technical Expertise: Implementing high-tech farming methods requires specialized knowledge and skills.
• Market Acceptance: Convincing consumers to adopt locally grown produce and accept potential price differences can be a hurdle.
• High Initial Investment: The setup costs for urban and vertical farming can be high, including technology, infrastructure, and skilled labor.
• Energy Consumption: Vertical farming often relies on artificial lighting and climate control, leading to increased energy consumption and costs.
• Limited Awareness and Education: Many people may not be familiar with urban and vertical farming techniques, necessitating awareness campaigns and training.

Way Forward:

• Government Support: The government can provide incentives, subsidies, and grants to promote urban and vertical farming. Policies that facilitate land allocation and ease regulations can encourage investment.
• Research and Development: Investing in research can lead to the development of more affordable and energy-efficient technologies suitable for Indian conditions.
• Skill Development: Training programs and workshops can help farmers acquire the technical skills needed for successful implementation.
• Community Engagement: Engaging local communities and educating them about the benefits of urban and vertical farming can generate support and demand.
• Public-Private Partnerships: Collaborations between the government, private sector, and research institutions can pool resources and expertise to drive innovation and reduce costs.

Conclusion

In this context, the Ministry of Housing and Urban Affairs in its “Operational Guidelines for the Implementation of Atal Mission for Rejuvenation and Urban Transformation (AMRUT)” report, aims to promote urban agriculture and rooftop farming as part of sustainable urban development initiatives. The report highlights that urban agriculture, both vertical farming or farming on vacant open spaces, can be a favourable way for ensuring food security and nutrition in India and around the world in the future.
