The World Association of Zoos and Aquariums (WAZA) is the "umbrella" organization for the world zoo and aquarium community. Its mission is to provide leadership and support for zoos, aquariums, and partner organizations of the world in animal care and welfare, conservation of biodiversity, environmental education and global sustainability.
After the International Union of Directors of Zoological Gardens (IUDZG), founded in 1935 at Basel, Switzerland, ceased to exist during World War II, it was refounded in Rotterdam in 1946 by a group of zoo directors from allied or neutral countries. In 1950 IUDZG became an international organisation member of International Union for the Protection of Nature.
In 1991 the IUDZG adopted a new name, World Zoo Organization, and revised its membership rules to include regional zoo associations.
In 2000 the organization got its current name, the World Association of Zoos and Aquariums, to reflect a more modern institution working together at a global level. The association wants to build cooperative approaches to common needs, tackle common issues, share information and knowledge. WAZA also represents the zoo community in other international bodies such as the
All members of the WAZA network are obliged to comply with “WAZA's Code of Ethics and Animal Welfare”, adopted by WAZA in 2003.
Members of the association include leading zoos and aquariums, and regional and national Associations of Zoos and Aquariums as well as some affiliate organizations, such as zoo veterinarians or zoo educators, from all around the world. Together they are 'United for Conservation'.
WAZA institutional members includes more than 250 zoos and aquaria.
In addition, about 1300 zoos are linked to WAZA through membership in one of the about 25 regional or national association members.
Outside of the WAZA associations with direct memberships, there are also regional organizations who are members of the WAZA through an affiliated regional organization.

Support for zoos and aquariums of the world
According to the organization, there are two characteristics that all the institutions known as ‘zoos’ have in common:
- Zoos possess and manage collections that primarily consist of wild (nondomesticated) animals, of one or more species, that are housed so that they are easier to see and to study than in nature.
- Zoos display at least a portion of this collection to the public for at least a significant part of the year, if not throughout the year.
The definition of "zoo" is a broad one and it may also incorporate aquariums, game reserves, aviaries, safari parks, rescue centers, sanctuaries or even so called "roadside zoos" where animals are often kept in problematic sub-standard conditions. In the view of the rest of the zoo community, which is committed to the principles of animal welfare and conservation, these roadside zoos do a lot of damage to the image of zoos in general and should be either assisted to reach a level of minimum standard or be closed down (which raises the problem what should be done with the animals they keep). Not all of sanctuaries are managed by experienced zoo professionals and staff, being able to deal with a variety of animals with different needs and requirements. Also the keeping conditions sometimes do not meet highest standards and in a number of instances the enclosures reach rather soon their carrying capacity, because it is usually very difficult if not impossible to release the animals into the wild (and also difficult to find suitable and appropriate places in zoos), making it impossible to further accept more animals. This may give rise to unjustified critique towards zoos in general in particular by some
- the conditions under which animals are kept, often precipitated by some unusual event such as an escape or an accidental death, and commonly expanded into a challenge of the legitimacy of holding any animals captive;
- euthanasia generally, but particularly as relates to the disposal of genetic surplus or highly sentient individuals;
- the feeding of live prey and, in some cases, whole animal carcasses;
- transfers of individuals between zoos, particularly when social relationships that are believed to have attributes in common with those of humans are ruptured as a result;
- the use of animals in entertainment, especially performing animals;
- bringing new animals in from the wild to augment captive holdings or to start new breeding programs;
- the employment of invasive technologies such as embryo manipulation or exogenous hormonal stimulation in breeding efforts;
- all research involving animals, even when it is the health and longevity of animals that could benefit.
The modern type zoo aims to keep healthy, physically sound animals in natural surroundings, allowing them to behave naturally and normally. What is done in the interests of the animals kept is also done in the interest of the zoo visitors, who can thus observe the animals as if they were in nature. The aims for the modern zoo are
Indeed, zoos are at present rapidly evolving to serve in multiple ways as conservation centres. Professional capacities of concern and subjects communicated to the public in earlier phases of zoo development are now vital services to conservation. As conservation centres, zoos must additionally address sustainable relationships of humankind and nature, explain the values of ecosystems and the necessity of conserving biological diversity, practice the conservation ethic throughout zoo operations and cooperate within the world zoo network and with other conservation organizations. In recent years, great emphasis has been placed on creating new and dynamic exhibits at zoos that provide significant enrichment opportunities for the animals on display while also offering visitors a unique viewing and learning experience. Immersion exhibits involve zoo visitors in the environmental circumstances of the animals and such experiences are conductive to favorable reception by visitors of strong conservation messages.
Only zoos, aquariums and botanic gardens can operate across the whole spectrum of conservation activities, from ex situ breeding of threatened species, research, public education, training and influencing and advocacy, through to in situ support of species, populations and their habitats. They uniquely have a massive ‘captive audience’ of visitors whose knowledge, understanding, attitude, behaviour and involvement can all be positively influenced and harnessed. They have a huge resource of technical skills and dedicated people. As habitats shrink and collection-managed populations grow, the definition of what is a zoo, what is a botanic garden, what is a reserve, and who is a collection-based conservationist, who is a field-based conservationist, will inevitably blur. Indeed, zoos, aquariums and botanic gardens have an opportunity to establish themselves as models of ‘integrated conservation’. In the German speaking part of Europe e.g. 45 zoos have united themselves in the “Foundation species conservation” with the purpose to advertise conservation projects on a large scale.
Today many animal species are threatened with extinction to a great extent because of increasing threats to their natural habitat. Zoos do not only keep such species in their custody with a view to maintaining ex situ reserve populations, but they increasingly link their
With the human population worldwide constantly increasing together with an ever increase in demand for resources, and destruction of natural habitats, the role of zoos as conservation centres and arks will become even more important in the coming years, combined with accumulating experience and knowledge on ex-situ and in-situ conservation by the worldwide zoo community, which is increasingly committed to integrated conservation.
WAZA-branding of in situ projects

Since these efforts are largely invisible to the general public, in 2003 WAZA started allowing organisations to request and use the WAZA brand on projects executed or supported by the WAZA constituency. Currently more than 150 projects around the world are WAZA branded.
The World Zoo and Aquarium Conservation Strategy
In 1993, The World Zoo Organisation (IUDZG) and the Captive Breeding Specialist Group of The World Conservation Union (IUCN) published The World Zoo Conservation Strategy. That strategy defined, for the first time in a single document, the responsibilities and opportunities that the international zoo and aquarium community needed, in order to be fully involved in nature conservation. The pressures and threats to wildlife remain and have indeed increased. The need for help in conservation has intensified. It is therefore an opportune time for all zoos and aquariums to re-examine the ways and means by which they can consolidate and increase their support and involvement in conservation. In 2005 a revised, second strategy, “Building a Future for Wildlife: the World Zoo and Aquarium Conservation Strategy”, was published by the World Zoo and Aquarium Association (WAZA). This document reinforces and expands the overall themes of the first document and presents a vision of the roles that all zoos and aquariums can and must play in the conservation of wildlife and of their ecosystems. The 72-page document, which is the result of assistance and advice from over 350 people, is truly international in its scope and in its production. The Strategy is aimed at all zoos and aquariums, however large or small, however rich or poor, and not just those that are members of WAZA. The Strategy provides a common philosophy for zoos and aquariums across the globe and defines the standards and policies that are necessary to achieve their goals in conservation. The 2005 Strategy will be of use and interest not to only zoo and aquarium people but to anyone concerned with biodiversity conservation and sustainable development. The document begins with a supportive foreword from the Director General of The World Conservation Union (IUCN), and a preface by the President of WAZA and by the Chair of the WAZA Conservation Committee, that set out the genesis and production of the Strategy. The document comprises nine chapters, with each chapter having a summary, a vision statement, a main text, conclusions, and a series of recommendations. This Strategy will be used by individual zoos and aquariums, by national and regional associations, and by WAZA itself, as the basis for the development of action plans for the implementation of the recommendations.
The document is available today in English, German and Russian. Bahasa, French, Japanese and Polish versions, as well as Urdu, Hindi, Bengali or Bangla, Dari and Singala summaries are currently under preparation.
In 2009, the World Zoo and Aquarium Conservation Strategy (WZACS) was especially implemented for the international aquarium community in the document entitled Turning the Tide: A Global Aquarium Strategy for Conservation and Sustainability.

Until today only few of the rare, endangered or extinct-in-the-wild species could be saved from complete extinction by keeping and breeding them in human care. But it may be well too early to really evaluate the contribution of zoos breeding programmes to the preservation of biodiversity.
Relationship with IUCN
- WAZA provides financial support to IUCN Species Survival Commissionand to its Specialist Groups, such as the South American Camelid Specialist Group.
- WAZA promotes the use of the newly developed IUCN Red List of Threatened Species branding and many zoos and aquariums have already in 2010 made use of it.
- WAZA has published on December 1, 2009, a book on ‘The Future of Wildlife’ to mark the 2010 International Year of Biodiversity, with contributions from partners including IUCN.
- WAZA supports international endeavours for amphibian conservation and is partnering with IUCN and its Conservation Breeding Specialist Group in the ‘Amphibian Ark’.
WAZA works in partnership with international organisations with a view to contribute to the conservation of biodiversity. Two examples of WAZA supported projects on the occasion of the International Year of the Gorilla 2009 are:

Zoos and aquariums appeal to a very broad audience and have huge visitor numbers throughout the world. They enable people to develop appreciation, wonder, respect, understanding, care and concern about nature. They therefore have the potential to be a very important source of environmental awareness, training and action for a sustainable future on a local, national, regional or international scale. In fact they are excellent centres in which to inform people about the natural world and the need for its conservation. Awareness can be converted into action with positive benefits for wildlife, people and conservation.
Living animals have an enormous power of attraction. Seeing, hearing and smelling them has huge educational significance in itself. The primary goal of living exhibits is education and educators increasingly are involved in the design of the exhibits. Animals are displayed in more natural settings, mixed exhibits and/or exhibits provide contextual story-led or message-driven experiences, using a variety of interpretation techniques. With an increasingly urbanized population, this contact with nature is of vital importance and zoos build on it to promote and support conservation. Visitors will then more easily understand the concepts of biodiversity and the interdependence of species, habitats and ecosystems, and recognize the links with human actions.
Zoos and aquariums have recognized that the visitors’ experience is also affected by the welfare of the animals and their enclosures. Zoos therefore ensure that positive educational messages are not compromised or confused by poor conditions or poor
Furthermore, enclosures clearly and correctly identify the animals in them. Signs highlight threatened species and species in regional, national and international coordinated breeding programmes.
A number of activities allow informal education, such as keeper talks, close encounters, hands-on experiences, exhibits that allow visitor access, exhibits with a clear biological theme. Whenever animal demonstrations form part of the programme, they contain an education or conservation message.
Resource material and education information is displayed and made available to the general public and zoo audience. This includes leaflets, guidebooks, teachers’ notes, resource packs and worksheets.
WAZA provides interactive, structured educational
WAZA encourages all of its staff to participate in local, national, regional and international networks such as the International Zoo Educators Association (IZEA) and its regional groups.
Today, through their living collections, zoos and aquariums can make a unique contribution to conservation-directed research. No other network of institutions can provide, as a resource for study, representative populations of so diverse an array of the world's wildlife. In addition, zoos and aquariums offer a rare venue for researchers and the public to meet and communicate, providing a platform for interpreting the outcome of research and explaining the implications for conservation action.
There are two main divisions of research in zoos and aquariums: (1) research that is aimed at new knowledge to help the institution achieve its goals, and (2) research that is undertaken in a zoo by others to achieve their own goals, without being inconsistent with those of the organization. Under the first division would fall research on husbandry, visitor preferences, educational and interpretation methods, conservation approaches etc., to a greater or lesser extent depending on a zoo's particular mission. The latter division would include assisting researchers from universities and research organizations by providing access to and or material from non-domesticated species for comparative analyses. It is impossible to describe all of the research undertaken by and at zoos and aquariums. Though there are areas of overlap, research can be divided into the following categories:
- research in pure and applied biological science (including
- in situ conservationresearch (e.g. field-based ecological and habitat research);
- research aimed at identifying and improving zoo and aquarium operations (for example research on visitor learning, the effectiveness of exhibits and programmes, marketing and messaging, membership, and development and fund-raising).
Zoos personnel know that this experience is possible only if visitors have the impression that the animals are healthy and well kept in naturalistic habitat-like enclosures. Therefore, when planning new exhibits today this is taken into consideration.
Care of animals
Within the twentieth century great strides had been made in the development of management methods and of principles and techniques relating to the maintenance of captive populations that increasingly satisfied the physical and psychological needs of the animals. Together with the increasing practical experiences in modern animal husbandry, various developments in the science of veterinary medicine (in particular prevention and control of parasites and causes of disease), enormous technical advances and the accumulation of knowledge of all kinds, it became possible to venture exhibits which before had not seemed possible. Zoos today provide exhibits of such size, volume, structure and objects as to allow the animals to express their natural behaviours. Also the animals are provided areas to which they may retreat. In addition separate facilities are available to allow separation of animals where necessary, e.g. cubbing dens. Efforts are made to protected animals at all times from conditions detrimental to their well-being.
Proper feeding management of wild animals in zoos and aquariums incorporates both husbandry skills and applied nutritional sciences. As a basic foundation of animal management, nutrition is integral to longevity, disease prevention, growth and reproduction. Additionally food collecting and/or gathering contributes to behavioral enrichment and provides occupation. Quite elaborate systems of food presentation (dead rats) have been developed (e.g. in Switzerland for wild cats), where computer programmed various mechanic devices allow the animals in the enclosure to search for prey as in their natural environment. However, in some cases animals in zoos need to be fed with other live animals, because they would not eat non-living food items. Whenever this has to be done however, the prey should have, as in natural conditions, a possibility to hide and it must be assured that the prey animal is killed as quickly as possible without pain and suffering. Whenever the animals accept dead prey or food items, they are not to be given live animals as food.
Indeed, most contemporary zoos led by professionals are aware of environmental enrichment, also called
Also the use of behavioral training, as another method of behavioral enrichment, has often contributed to the animals well-being as well as allowed zoos to improve dramatically their ability to care for animals, while reducing animal stress and increasing safety for both keeper and animal during care procedures. It is self-evident that such training must be done by expert keepers in a way that is appropriate to the animals, based on biological and scientifically sound learning principles.
Management of animals
At the beginning of the twentieth century, zoos acquired many animals that were caught in the wild. Today however zoos acquire animals much more frequently through their ex-situ breeding programs, trade or exchange (or loans and gifts) among zoos (often following the advice of the appropriate Species Co-ordinators). Zoos make sure that institutions receiving their animals have appropriate facilities to hold them and skilled staff that are capable of maintaining the same high standard of husbandry and welfare as they themselves. However it is recognized that, from time to time, there is a legitimate need for conservation breeding programs, education programs or basic biological studies, to obtain animals from the wild. The collection, trade, and transport of wild animals is strictly regulated today by national and international legislation (in particular
The situation is somewhat different for aquaria, where – although an increasing number of fish and invertebrates can be bred in human care – still newly acquired animals are predominantly wild-caught. One of the reasons is that reproduction in aquaria just has not been possible yet or is – still – too expensive.
In fact the World Zoo Conservation Strategy published in 1993 states "that the commercial wild animal trade as a source of zoo animals should cease as soon as possible. Such animals as must be collected from the wild must be collected for specific educational and conservation purposes. They should not be chosen from dealers’ lists of animals randomly collected for commercial purposes." These goals, while more pertinent in 1993, are still valid and show up again in the World Zoo and Aquarium Conservation Strategy published in 2005. Since then, this has meant that zoos disapprove of selling their “surplus” animals to animal dealers, auctions and game farms, unaccredited zoos and individuals without the necessary knowledge and expertise, respectively without the keeping-license required by national legislation.
All animals being transferred are usually accompanied today by appropriate records with details of health, diet, reproductive and genetic status and behavioural characteristics having been disclosed at the commencement of negotiations. These records will allow the receiving institution to make appropriate decisions regarding the future management of the animal. All animal transfers must conform to the international standards and laws applying to the particular species. Where appropriate or required by legislation, animals are accompanied by qualified staff.
In keeping with the requirements of animal welfare standards, the adaptive capacity of wild animals in zoos must not be compromised, nor their functional capabilities allowed to atrophy. Furthermore, animals in zoos must be kept in a manner that accommodates their natural behaviour. Reproductive behaviour is central to this consideration. Reproduction in all its aspects (
- Relocate surplus to other suitable and appropriate facilities.
- Release to sanctuaries.
- Release into the wild within the framework of coordinated species recovery projects, respecting the IUCNguidelines and all legal requirements.
- Temporarily impede reproduction in a humane and ethical manner (group management, sterilization, artificial inseminationetc.).
When contraception is considered, the possible side effects of both surgical and chemical contraception, as well as the negative impact on behavior and social structure of the group should be considered before the final decision to implement contraception is made.
When all options have been investigated and none of these measures are feasible without causing stress or impacting upon group behaviour and the decision is taken that it is necessary to euthanize an animal, care will be taken to ensure it is carried out in a fear free environment and a manner that ensures a quick death without suffering. Euthanasia may be controlled by local customs and laws but should always be used in preference to keeping an animal alive under conditions which do not allow it to experience an appropriate quality of life. Whenever possible a post-mortem examination should be performed and biological material preserved for research and gene conservation. If ethics and legislation allows it, there is nothing wrong with “recycling” remains of such animals into the zoo's own food chain.
Zoos usually avoid talking about death. In particular, they do not convey that sometimes it may be unavoidable to kill animals with a view of keeping a breeding programme alive and viable. The largest problem for long-term conservation breeding at zoos will be the lack of understanding by the public that nature is based on surplus, i.e. that always more animals are born than are necessary for maintaining their own species, and that these surplus animals will end up in the food chain, thus ensuring the survival of other species.
