Urban Agriculture for Human and Planetary Health

Urban Farm DB summary

A book chapter addresses rising food and nutritional insecurity from rapid urbanization in Sub-Saharan Africa, South Asia and elsewhere, noting that 55% of the world population currently lives in cities, projected to reach 70% by 2050. It states that as much as 10-20% of food consumed could be grown within city limits, but that careful planning is needed to reduce risks from soil contamination, plastic pollution, and reuse of grey/black water and city-waste compost. It identifies rooftop gardens, multistory glass buildings, and soil-less methods such as aquaculture, hydroponics and aeroponics as modern forms of urban agriculture, and discusses barriers including land tenure and research priorities for scaling up.
