In February 2003, the Governing Council of UNEP adopted a long-term strategy for engaging young people in environmental activities and in the work of UNEP. The strategy was entitled the TUNZA Youth Strategy. The word “TUNZA” means “to treat with care or affection” in Kiswahili (a sub-regional language of Eastern Africa). The overall TUNZA Concept, therefore, is built around this theme. It is an initiative that is meant to develop activities in the areas of capacity building, environmental awareness, and information exchange, with a vision to foster a generation of environmentally conscious citizens, capable of positive action.

Important by-products of this strategy include the annual TUNZA International Youth Conference, Tunza Advisory Council, TUNZA magazine, and the book "A Time for Action" provide up-to-date information and resources that support the environmental empowerment of young people.
