Today is the second day of the Urban Agriculture Summit 2013 ’Transformative solutions on how we feed people in the urban era’ currently being held in Linköping, Sweden (29-31 January). So why this specific gathering on urban agriculture? A recent UN report estimated that the Earth’s population will increase by 40% and exceed 9 billion people by the year 2050. Simultaneously, 80% of the world’s population will live in cities. This rapid urbanization goes together with a rapid increase in urban poverty and urban food insecurity. With traditional farming practices and increases in consumption, the Earth’s arable land will soon no longer be sufficient to produce enough food for the growing population. Urban agriculture can provide a complementary strategy to reduce urban poverty and food insecurity and enhance urban environmental management.
