A review on urban farming: Potential, challenges and opportunities

Abstract

Urban farming has emerged as a promising solution to address food security in cities. It encompasses several farming models, such as community, indoor, rooftop, and vertical farms, equipped with various farming techniques like aeroponics, hydroponics, and aquaponics. However, sustainability and yield remain major challenges to fully realize its potential. To gain more insights, we have analysed scientific literature and interviewed urban farmers. Key challenges identified include limited land and water resources, incidences of pests and diseases, financial constraints for setup and maintenance, knowledge and skill gaps among participants, and lack of effective collaboration between universities, government, and industries. This review discusses global initiatives in urban farming, different types of farming models, their benefits and challenges, and explores opportunities to address these challenges. The insights gained from this study will serve as a resource for the establishment of urban farms and the development of strategies aimed at enhancing the sustainability of urban farming.
