Friends of Nature (international abbreviation: NFI, for German: Naturfreunde International) is a non-profit organisation with a background in the social democratic movement, which aims to make the enjoyment of nature accessible to the wider community by providing appropriate recreational and travel facilities. It encourages sustainable tourism and international friendship. It is also known as Naturfreunde (German), Les Amis de la Nature (French), Amici della Natura (Italian), La Naturamikoj (Esperanto), and Natuurvrienden or NIVON (Dutch). Background The International Friends of Nature (IFN), based in Vienna, is the umbrella organisation of the national Friends of Nature federations. Publications of the various sections include a handbook detailing all the houses and magazines published by various sections (such as Naturefriends - Great Britain - Bulletin, Les Amis de La Nature, La Migranto – in Esperanto by "Esperantistoj Naturamikoj" etc.). Tradition The Friends of Nature organisation was founded in Vienna in 1895.The group was founded by three activists, Karl Renner, a law student and future President of Austria, Georg Schmiedl, a schoolteacher, and Alois Rohrauer, a blacksmith. In the age of incipient tourism, the organisation succeeded in making nature accessible to broader population strata by providing requisite recreational and travel facilities. The organisation was banned by the Nazis in 1933, but revived in 1945. Commitment to sustainable development International environmental campaigns, such as "100,000 Trees for Europe" or "Blue Rivers for Europe" are intended to enhance environmental awareness in Europe and to offer members opportunities to take action in the interest of the environment. In 1995, the Friends of Nature set up the "Institute for Integrative Tourism". The "Manifesto for a New Europe" (1993) and the "Manifesto for a Social, Ecological and Peaceful Future" (1996) proposals submitted to the Inter-governmental Conference of the European Union, and the "Green Paper - The Alps" are examples of international lobbying by the Friends of Nature. Friends of Nature worldwide With 350,000 members organised in approximately 45 member organisations, the Friends of Nature are among the biggest non-profit and non-governmental organisations worldwide. They provide environmentally sound travel programmes for their members and run over 700 Nature Friends Houses mainly in Europe. The houses vary in size and facilities.
