Internationale Grüne Woche Berlin

Berlin International Green Week (German: Internationale Grüne Woche Berlin), also called simply Green Week, is an important international trade fair held annually in Berlin, Germany, for processors and marketers in agriculture, horticulture and various food industries. Green Week traditionally takes place at the beginning of the year in the exhibition halls under the Funkturm and is open to the general public. In 2010 it had around 400,000 visitors. That same year, the Paris International Agricultural Show (French: Salon International de l'Agriculture) had 650,000 visitors.

The fair is accompanied every year by protests themed We are fed up!. Since to 2011 between 15,000 and 30,000 people join the demonstrations against and for more sustainable farming.

The first green week (at that time still not "international") was held from 20 to 28 February 1926, when an employee at the Berlin Tourism Office had the idea to combine the traditional winter meeting of the German Agricultural Society with an agricultural exhibition as a secondary showcase for fair participants. Green Week owes its name to the green felt coats (German: Lodenmäntel) worn by German foresters and farmers. In the first year, there were 50,000 visitors and the fair had covered an area of 7,000 m².

Green Week took place every year until 1939, with the exception of 1938 because of an outbreak of European foot-and-mouth disease. After the devastation of World War II, Green Week resumed in 1948. After a break in 1951 due to major postwar construction, the fair was held again in 1951 and every year since. Participation of foreign exhibitors increased continuously: by 1963 they accounted two-thirds of exhibitors. After German reunification in the 1990s, Green Week grew substantially. Special shows on topics such as "German Cheese" and since 2005 a technical program of over 250 lectures, seminars and symposia round off the exhibition.
