Farmer Tom Chino works in the field of his family's farm as spring onions grow under cloudy skies in Rancho Santa Fe, California March 7, 2013. The gravitational pull of Chino Farm is legendary. Since they don't ship, everyone - whether a top chef or a traveling foodie or a local resident - comes to the farm stand, simply called "Vegetable Shop," on a dusty corner of this affluent San Diego County town, hemmed in by sprawling housing estates. Long before farmers' markets and heirloom vegetables popped up across the country, Tom Chino's parents bought the 45-acre (18.2-hectare) farm after World War Two and forged their independence from wholesalers and supermarkets, setting their prices and cultivating a diverse offering of crops.

Scallions are displayed at a local food market in Nigeria's central city of Jos February 15, 2011. More than 200 people have been killed in sectarian violence in and around Jos since a series of bombs shattered Christmas Eve celebrations almost two months ago. The economy of Plateau state, of which Jos is the capital, had relied on the fruit and vegetable it supplies to cities across Africa's most populous nation, and on tourism, after mining and manufacturing firms scaled down or moved away. Rivalry for scant economic opportunities combined with local government policies that have actively discriminated against non-indigenes have fuelled divisions. Picture taken February 15, 2011.

Max Kipp, a student at the Rijn IJssel school for chefs, stir-fries mealworms with spring onions to be used in a quiche in Wageningen January 12, 2011. All you need to do to save the rainforest, improve your diet, better your health, cut global carbon emissions and slash your food budget is eat bugs. Mealworm quiche, grasshopper springrolls and cuisine made from other creepy crawlies is the answer to the global food crisis, shrinking land and water resources and climate-changing carbon emissions, Dutch scientist Arnold van Huis says. To attract more insect-eaters, Van Huis and his team of scientists at Wageningen have worked with a local cooking school to produce a cookbook and suitable recipes. Picture taken January 12.

Mealworms and spring onions are stir-fried to be used in a quiche at the Rijn IJssel school for Chefs in Wageningen January 12, 2011. To try and get wider support for their attempts to introduce insects on the menu of the top restaurants, scientists at the Wageningen University teamed up with the local cook academy.
Quiche with mealworms, springrolls with roasted grasshoppers and chocolate pralines with buffalo worms do not make ideal menu for housewarming parties, but in a few decades could be on dinner tables in many European countries as scientists seek ways to replace expensive meat.

Vendors package spring onions as they wait for customers at an outdoor fruit and vegetable market located on the outskirts of Beijing December 17, 2010. China's inflation soared past forecasts to a 28-month high in November and showed signs of spreading beyond food prices, putting pressure on the government to tighten monetary policy. China is striding into an era where higher inflation will become a more permanent feature of its economic landscape, a shift that the government, long assumed to have zero tolerance for rising prices, is showing signs of accepting.
