Vertical Farming: An Assessment of Singapore City

Urban planners, government leaders, and the farming community have noted the important role cities play in producing their own food to manage higher levels of domestic demand, food insecurity, environmental concerns and affordability. To better understand these issues our research examines urban farming; in particular, the use of vertical farming methods. Such approaches can be used to overcome not only food safety and land resource issues, but also better manage the threats posed by rapid urbanisation. With technological developments in hydroponics, aeroponics and aquaponics, vertical farming has become a much more efficient and affordable means of farming in urban spaces. Overall, these high-tech systems signify a shift in the ways farming and food production can be operationalised. The results from our analysis show that Singapore, a tropical city in Asia, is making significant strides in vertical farming with substantial public and private investment in R&D through high-tech, high-yielding, land-limited farms in high-rise buildings. Despite these initiatives, Singapore faces a highly constrained urban environment where land scarcity is exacerbated by a complex regulatory land use framework.
