BERLIN, Jan. 15 (Xinhua) -- The 75th International Green Week in Berlin, the world's largest agricultural and food fair opened doors to the public Friday.

    Some 1,600 exhibitors from 56 countries will show visitors their best agriculture products, livestock, farm machines, garden tools and newly-developed technologies.

    Organizers of the fair were expected to receive 400,000 people over the next 10 days, with Hungary as this year's guest of honor. Various sample foods and drinks, traditional and modern, were waiting for visitors to have a taste.

    "The Green Week is an evergreen," said Christian Goeke, the main organizer of the fair. "As it marks this significant anniversary, this event remains immune to crisis and continues to maintain its stability at a high level."

    With the theme "agriculture and climate change," the Global Forum for Food and Agriculture 2010 is the major importance of the event, which is taking place from Jan. 14 to Jan. 16, attended by more than 50 agriculture ministers.

    "When it comes to climate change, the agriculture sector is a victim and perpetrator at the same time," said Ilse Aigner, Germany's agriculture minister Thursday. "If agriculture wants to produce more to feed all people on our planet, it has to be more productive and do it in a way that saves the climate."

    Aigner hoped that her counterparts could better ideas on how to restructure the 21st-century agriculture under changing climate conditions, when they left her country after the panels.

    "We should be realistic: making agriculture climate-neutral and still have sufficient food production for all will be very difficult," she said.
