Urban foraging, resilience and food provisioning services provided by edible plants in interstitial urban spaces in Mexico City

Urban Farm DB summary

Two surveys mapped the distribution of edible plant species growing in publicly accessible interstitial spaces — such as central reservations and pavements — in subtropical central Mexico City (CDMX), walking roughly 20 km of streets and identifying 36 species of edible plants including fruits, herbs and vegetables. Of five feasibility conditions for using these spaces for foraging, three — suitable growing conditions, provisioning capability, and the existence of multiple plant dispersal pathways — could be satisfactorily assessed, while two — usage and a favourable planning environment — could not be judged from the field data. Rather than improving everyday food supplies, maintaining these spaces for emergency foraging was framed as a way to increase urban resilience against extreme food supply shocks. CDMX promotes planting fruit trees along avenues, but the survey found local socio-ecological systems sustain a greater variety of edible plants across a wider range of interstitial spaces.
