Food access in cities is primarily achieved through food purchases, where households convert assets into food at retail locations. When a household falls into food insecurity through trading household assets for resources, it is often trapped by a host of resource deprivations that have occurred over time. In this manner, the process compounds the vulnerability of a household to food insecurity. At the level of the individual household, vulnerability is defined in part by the ability to access essential resources and services.application/pdfenURBANIZATIONLOCAL FOOD SYSTEMSINCLUSIVE GROWTHFOOD SECURITYINFRASTRUCTURECITIESVULNERABILITYMODELLINGACCESS TO RESOURCESURBAN POORPOVERTYKINGSTONMAPUTOMEXICO CITYNAIROBIGLOBAL SOUTHWorking Paper
