What can the arid agriculture movement learn from the success of urban agriculture?

摘要

One response to the desertification that climate change has engendered has been the rise of non-traditional agricultural clusters,such as urban agriculture.Urban agriculture has long been a fixture of the global agriculture market,where it is defined by Mougeot in1999 as “an industry located within(intra-urban)or on the fringe(peri-urban)of an urban center… which grows or raises,processes and distributes a diversity of food and non-food products,reusing and supplying [local products and services]”.The Food and Agriculture Organization of the United Nations(FAO)estimates that 10％or more of Sub Saharan Africa's urban population,or around 11 million people,are active in urban agriculture,providing about a fifth of the world's food.
