4. FAO:
The rapid growth of cities in the developing world is placing
enormous demands on urban food supply systems.
Agriculture – including horticulture, livestock, fisheries, forestry,
and fodder and milk production – is increasingly spreading to
towns and cities. Urban agriculture provides fresh food, generates
employment, recycles urban wastes, creates greenbelts, and
strengthens citiesʼ resilience to climate change.
