Urban agriculture among poorer communities in lower income areas is already an important source of food supply for those communities, contributing to food security and health . However, potential for expanding open air urban food production may be practically constrained by land availability . This is particularly true in some lower-income countries where rapid urbanisation is occurring, which compounds existing food insecurity . Land availability and suitability for gardens can be further constrained by land use history, including past industrial uses that can contaminate soils with pollutants such as lead.
