ATPNE was founded in 1971 and joined FoEI in 1995. With 20 local groups, ATPNE is an important environmental defender in Tunisia. It also maintains a high profile outside the country for its work as the representative of Northern African NGOs in the International Union for the Conservation of Nature (IUCN).
ATPNE's campaigns focus on agriculture, biodiversity, forests, animal protection and pollution, and they recently launched an awareness campaign. The organization works by carrying out field projects with local people (especially rural women), performing studies, giving advice, and participating in seminars and other events. ATPNE also lobbies the government for improved environmental legislation.
