The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable".2

The story

IUCN was established in 1948. It was initially called the International Union for the Protection of Nature (1948–1956) and has also been formerly known as the World Conservation Union (1990–2008). The history of the International Union for Conservation of Nature is described below.

Establishment

IUCN was established on 5 October 1948, in Fontainebleau, France, when representatives of governments and conservation organizations spurred on by UNESCO signed a formal act constituting the International Union for the Protection of Nature (IUPN). The initiative to set up the new organization came from UNESCO and especially from its first director general, the British biologist Julian Huxley.

At the time of its founding, IUCN was the only international organization focusing on the entire spectrum of nature conservation (an international organization for the protection of birds, now BirdLife International, had been established in 1922).

Early years (1948–1956)

IUCN (International Union for Conservation of Nature) started out with 65 members in Brussels and was closely associated with UNESCO. They jointly organized the 1949 Conference on Protection of Nature in Lake Success, New York, and drafted the first list of gravely endangered species. In the early years of its existence IUCN depended almost entirely on UNESCO funding and was forced to temporarily scale down activities when this ended unexpectedly in 1954. IUCN was successful in engaging prominent scientists and identifying important issues such as the harmful effects of pesticides on wildlife but not many of the ideas it developed were turned into action. This was caused by unwillingness to act on the part of governments, uncertainty about the IUCN mandate and lack of resources. In 1956, IUCN changed its name to International Union for Conservation of Nature and Natural Resources.

Increased profile and recognition (1956–1965)

During this period, the IUCN expanded its relations with UN-agencies and established links with the Council of Europe. IUCN's best known publication, the Red Data Book on the conservation status of species, was first published in 1964. IUCN began to play a part in the development of international treaties and conventions, starting with the African Convention on the Conservation of Nature and Natural Resources. Africa was the focus of many of the early IUCN conservation field projects. IUCN supported the 'Yellowstone model' of protected area management, which severely restricted human presence and activity in order to protect nature.

The IUCN also suffered from restricted financing in its early years. For this reason, Tracy Philipps, secretary-general from 1955 to 1958, did not draw a salary during his period in office. To establish a stable financial basis for its work, IUCN participated in setting up the World Wildlife Fund (1961) (now the World Wide Fund for Nature (WWF)) to work on fundraising to cover part of the operational costs of IUCN. Also in 1961, the IUCN headquarters moved from Belgium to Morges in Switzerland.

Consolidating its position in the international environmental movement (1966–1975)

During the 1960s, IUCN lobbied the UN General Assembly to create a new status for NGOs. Resolution 1296, adopted in 1968, granted 'consultative' status to NGOs. IUCN itself was eventually accredited with six UN organizations. IUCN was one of the few environmental organizations formally involved in the preparations of the United Nations Conference on the Human Environment (Stockholm, 1972). The Stockholm Conference eventually led to three new international conventions, with IUCN involved in their drafting and implementation:

Convention Concerning the Protection of World Cultural and Natural Heritage (1972). IUCN co-drafted the World Heritage Convention with UNESCO and has been involved as the official Advisory Body on nature from the onset.[8]

CITES – the Convention on International Trade in Endangered Species of Wild Fauna and Flora (1974). IUCN is a signatory party and the CITES secretariat was originally lodged with IUCN.

Ramsar Convention – Convention on Wetlands of International Importance (1975). The secretariat is still administered from IUCN's headquarters.

IUCN entered into an agreement with the United Nations Environment Programme UNEP to provide regular reviews of world conservation. The income this generated, combined with growing revenue via WWF, put the organization on relatively sound financial footing for the first time since 1948. This period saw the beginning of a gradual change in IUCN's approach to conservation in which it tried to become more appealing to the developing world.

The World Conservation Strategy (1975–1985)

In 1975 IUCN started work on the World Conservation Strategy (1980). The drafting process, and the discussions with the UN agencies involved, led to an evolution in thinking within IUCN and growing acceptance of the fact that conservation of nature by banning human presence no longer worked. The Strategy was followed in 1982 by the World Charter for Nature, which was adopted by the United Nations General Assembly, after preparation by IUCN.

In 1980, IUCN and WWF moved into shared new offices in Gland, Switzerland. This marked a phase of closer cooperation with WWF, but the close ties between IUCN and WWF were severed in 1985 when WWF decided to take control of its own field projects, which so far had been run by IUCN.

Sustainable development and regionalization (1985 to present day)

In 1982, IUCN set up a Conservation for Development Centre within its secretariat. The Centre undertook projects to ensure that nature conservation was integrated in development aid and in the economic policies of developing countries. Over the years, it supported the development of national conservation strategies in 30 countries. Several European countries began to channel considerable amounts of bilateral aid via IUCN's projects. Management of these projects was primarily done by IUCN staff, often working from the new regional and country offices IUCN set up around the world. This marked a shift within the organization. Previously, the volunteer Commissions had been very influential, now the secretariat and its staff began to play a more dominant role. In 1989, IUCN moved into a separate building in Gland, close to the offices it had shared with WWF. Initially, the focus of power was still with the Headquarters in Gland but the regional offices and regional members' groups gradually got a bigger say in operations.

In 1991, IUCN (together with UNEP and WWF) published Caring for the Earth, a successor to the World Conservation Strategy. Social aspects of conservation were now integrated in IUCN's work; at the General Assembly in 1994 the IUCN mission was redrafted to its current wording to include the equitable and ecologically use of natural resources.

Closer to business (2000 to present day)

Since the creation of IUCN in 1948, IUCN Members have passed more than 300 resolutions that include or focus on business related activities. The increased attention on sustainable development as a means to protect nature brought IUCN closer to the corporate sector. The members decided against this, but IUCN did forge a partnership with the World Business Council for Sustainable Development. IUCN renewed a multi-year MOU (Memorandum of understanding) with WBCSD in December 2015.

In 1996, after decades of seeking to address specific business issues, IUCN's Members asked for a comprehensive approach to engaging the business sector. Resolution 1.81 of the IUCN World Conservation Congress held that year "urged IUCN Members and the Director General, based on the need to influence private sector policies in support of the Mission of IUCN, to expand dialogue and productive relationships with the private sector and find new ways to interact with members of the business community".

The IUCN Global Business and Biodiversity Program (BBP) was established in 2003 to influence and support private partners in addressing environmental and social issues. In 2004, the first IUCN Private Sector Engagement Strategy was developed (in response to Council Decision C/58/41). Most prominent in the Business and Biodiversity Program is the five-year collaboration IUCN started with the energy company Shell International in 2007.

IUCN has been involved in minimum energy consumption and zero-carbon construction since 2005 by integrating energy-saving materials, developed by Jean-Luc Sandoz in the footsteps of Julius Natterer. Today, the Business and Biodiversity Programme continues to set the strategic direction, coordinate IUCN's overall approach and provide institutional quality assurance in all business engagements. The Programme ensures that the Business Engagement Strategy is implemented through IUCN's global thematic and regional programmes as well as helps guide the work of IUCN's six Commissions.

Championing Nature-based Solutions (2009 to present day)

Nature-based solutions (NbS) use ecosystems and the services they provide to address societal challenges such as climate change, food security or natural disasters.

The emergence of the NbS concept in environmental sciences and nature conservation contexts came as international organizations, such as IUCN and the World Bank, searched for solutions to work with ecosystems rather than relying on conventional engineering interventions (such as a seawall), to adapt to and mitigate climate change effects, while improving sustainable livelihoods and protecting natural ecosystems and biodiversity. At the IUCN World Conservation Congress 2016, IUCN Members agreed on a definition of nature-based solutions. Members also called for governments to include nature-based solutions in strategies to combat climate change.

IUCN Programme (2017–2020)

According to its website, IUCN works on the following themes: business, climate change, economics, ecosystems, environmental law, forest conservation, gender, global policy, marine and polar, protected areas, science and knowledge, social policy, species, water, and world heritage.

IUCN works on the basis of four-year programs, determined by the membership. In the IUCN Programme for 2017–2020 conserving nature and biodiversity is linked to sustainable development and poverty reduction. IUCN states that it aims to have a solid factual base for its work and takes into account the knowledge held by indigenous groups and other traditional users of natural resources. The IUCN Programme 2017–2020 identifies three priority areas:

Valuing and conserving nature.

Promoting and supporting effective and equitable governance of natural resources.

Deploying Nature Based Solutions to address societal challenges including climate change, food security, and economic and social development.

IUCN does not itself aim to directly mobilize the general public. Education has been part of IUCN's work program since the early days but the focus is on stakeholder involvement and strategic communication rather than mass-campaigns.
