Walking into the Felix Thomas REWE(德国大型连锁超市) supermarket in Lankwitz, Berlin, customers are immediately presented with a choice of greens(绿叶蔬菜): romaine(罗马生菜), rocket(芝麻菜), iceberg. But last month, a new option joined the selection: Lankwitz loose-leaf lettuce(散叶生菜). A combination of head lettuce, romaine lettuce, Lollo Rosso, and dark green easy leaf lettuce, its yellow packaging makes it stand out(显眼、突出) in a row of green. But it’s not just the flashy(花哨的) packaging that makes it distinct. Unlike its neighbouring lettuces, which come from regional farms or all the way from Italy, these greens were grown just a few metres away – or rather, a few metres up.(与旁边那些来自地区农场甚至远从意大利运来的生菜不同，这些绿叶菜就长在几米之外——更准确地说，是几米之上。) “Frisch Vom REWE Dach” or “Fresh from the REWE roof”, the bags read.
走进柏林兰克维茨的Felix Thomas REWE超市，顾客迎面就会看到各种绿叶菜可供选择：罗马生菜、芝麻菜、卷心生菜。但上个月，选择中又多了一个新成员：兰克维茨散叶生菜。它由结球生菜、罗马生菜、红菊苣和深绿色易叶生菜混合而成，黄色包装让它在满架绿色中格外显眼。但让它与众不同的不只是花哨的包装。与旁边那些来自地区农场甚至远从意大利运来的生菜不同，这些绿叶菜就长在几米之外——更准确地说，是几米之上。袋子上写着“Frisch Vom REWE Dach”，即“新鲜来自REWE屋顶”。
Rooftop farms are nothing new(并不新鲜): in cities such as Paris, Hong Kong, Copenhagen and New York, similar farms supply food to adjacent(邻近的) food retailers or even restaurants. This model has the potential to reduce greenhouse gas emissions from transportation (and its associated costs), minimise the urban heat effect, make use of dead space and perhaps even improve the relationship between buyers and their food.(这种模式有望减少交通运输产生的温室气体排放（以及相关成本），缓解城市热岛效应，利用闲置空间，甚至可能改善消费者与食物之间的关系。)
屋顶农场并非新鲜事物：在巴黎、香港、哥本哈根和纽约等城市，类似的农场为邻近的食品零售商甚至餐厅供应食材。这种模式有望减少交通运输产生的温室气体排放（以及相关成本），缓解城市热岛效应，利用闲置空间，甚至可能改善消费者与食物之间的关系。
Germany is also no stranger to(对……并不陌生) rooftop farms. In 2021, REWE and ECF – a Berlin-based agricultural technology company – opened their first green farming market on top of a store in Wiesbaden-Erbenheim(德国城市威斯巴登的一个区), selling basil(罗勒) below. But at 2,760 sq metres(平方米), the Lankwitz REWE is now Germany’s largest rooftop farm.
德国对屋顶农场也并不陌生。2021年，REWE与总部位于柏林的农业科技公司ECF在威斯巴登-埃尔本海姆一家门店的屋顶开设了首个绿色农场超市，在楼下售卖罗勒。但兰克维茨REWE农场占地2760平方米，如今已是德国最大的屋顶农场。
