Enabling circularity for food safety: the rooftop farming model

Abstract

Population growth, environmental change, urbanization, consumption patterns, waste, the global political climate, conflicts, and infectious diseases all exert a strain on global food security. Access to sufficient and nutritious food is becoming increasingly problematic, particularly for individuals living in less developed and developing countries. More individuals are becoming aware of the significance of developing a "Green Economy" approach to ensure global food security. A multifaceted strategy is required to ensure global food security. This study emphasizes the need for regional self-sufficiency for the transition to a green economy, and as a model proposal, it is suggested that it would be beneficial to encourage and develop farming operations on the roofs of residential, commercial, and public housing in urban regions. Rooftop farming, as one of the urban agriculture practices, can be utilized as a strategic instrument to achieve a variety of key aims, including enhancing the local economy, reducing inequality, internalizing responsible production and consumption by society, improving the quality of urban life, and more. Furthermore, because of the novel production processes seen in urban agriculture, circularity in production and consumption, a key component of the transition to a green economy, can be realized. "Self-sufficiency" is one of the concepts underlined in this study. The study also includes real cases highlighting the potential benefits of rooftop farming.
