In march 2013 I visited Mumbai. Driving on the Urban train I discovered small gardens along the rail tracks. For me this is the best example of urban farming I ever saw. Our western fashionable roof gardens are nice but more an awareness thing than an actual problem solver. These railway gardens are for me a example of innovation and creativity. Because free soil is very scarce in Mumbai these farmers found the only place in this city to grow food, between and next to the railways. A nice side effect of this location is that its graded by railway police and there is free irrigation of sewer water. The farmers sell there vegetables on the market and earn around 100 euro a month.
