On 4 April 2010 Sabancı Foundation's "Turkey's Changemakers" program hosts Gülcan Nitsch; an idealist biologist, who has been working for raising environmental awareness among the Turkish community in Berlin-Germany.

Gülcan Nitsch, who is the first participant of Turkey's Changemakers from Europe, started to promote environmental issues in the Turkish community in Berlin when she was working with women and children at BUND, Friends of the Earth Germany.

BUND is a non-governmental ecology group located in Berlin and German branch of an international network of environmental organizations. Nitsch established an environmental group within BUND, called the Green Belt, and has organized the Turkish Environment Day for 3 years through which she encourages the Turkish community to actively participate. In addition to this, Green Belt organizes information meetings, discussion groups for women, and trekking activities, and distributes brochures.

Today, Green Belt has become an influential environmental group with more than 20 active members, and 100 supporters. Thanks to the activities of Green Belt, hundreds of people, especially Turkish people, who have problems with understanding German, have been informed about environmental issues. Green Belt received an award in 2009 from the Representatives of Berlin Senate for Integration and Migration for supporting the integration of migrants in Germany. With the prize money, Gülcan Nitsch started publishing a journal on environmental issues in Turkish.
