SCIENTIFIC SEMINAR ON AVIAN INFLUENZA, THE ENVIRONMENT AND 
MIGRATORY BIRDS: 

10-11 APRIL 2006

The Scientific Seminar on Avian Influenza, the Environment and 
Migratory Birds met from 10-11 April 2006 at UN Office in Nairobi, 
Kenya. The Seminar was organized by the United Nations Environment 
Programme (UNEP) Division of Early Warning and Assessment (DEWA) 
in cooperation with the Convention on Migratory Species of Wild 
Animals (CMS) and its Agreement on the Conservation of African-
Eurasian Migratory Waterbirds (AEWA). Around 25 invited experts 
from relevant disciplines attended the Seminar, including 
scientists and representatives from various organizations. Invited 
observers included UNEP Country Permanent Representatives and 
representatives from other UN organizations. A total of 55 
participants were in attendance.

The Seminar aimed to review the latest scientific studies 
concerning the evolution and spread of Highly Pathogenic Avian 
Influenza (HPAI), subtype H5N1, and its impact on wild birds and 
the wider environment, including assessing risks of transmission 
and identifying optimal mitigation measures. 

The Seminar’s output included a press release and a summary 
document with recommendations for decision makers, the media and 
other stakeholders on action to be taken in light of the latest 
scientific findings on HPAI and in the context of conservation and 
the environment. These recommendations address: surveillance, 
early warning and risk assessment; priority short-term needs; 
longer-term needs; collaboration and cooperation; and next steps. 

A BRIEF HISTORY OF AVIAN INFLUENZA IN THE CONTEXT OF MULTILATERAL 
ENVIRONMENTAL AGREEMENTS

HPAI, subtype H5N1, is an influenza A virus very similar to the 
“ordinary” influenza that has always affected human beings. Avian 
influenza viruses are classified according to the composition of 
two surface proteins, hemagglutinin (H) and neuraminidase (N). 
Currently there are 16 known H-subtypes (H1 through H16) and nine 
known N-subtypes (N1 through N9). Avian influenza viruses 
originate in wild birds, particularly waterbirds, and are usually 
not dangerous to their hosts. However, after transfer to a new 
type of host, either avian or mammalian, influenza viruses 
sometimes undergo rapid evolution and may develop into new, highly 
pathogenic strains that pose serious threats to humans, poultry 
and wild bird populations. The infamous Spanish flu pandemic, 
which killed between 40 and 100 million people in 1918, was a 
highly pathogenic H1N1 strain that originated in birds.

The current highly pathogenic avian influenza (HPAI) strain, 
subtype H5N1, is believed to have emerged in 2002. To date, over 
200 million domesticated birds have been killed by the virus or 
culled to stem its spread. This strain has acquired the capability 
to infect humans: the World Health Organization (WHO) reports that 
more than 190 people have been infected, over 100 of whom have 
died, predominantly in South-East Asia. Currently, the virus does 
not spread from human to human, but it is feared that only a minor 
adaptation is needed for it to develop the necessary 
characteristics. Such an adaptation would allow the virus to 
become pandemic. 

HPAI was recently found to affect felid species, including 
domestic cats, as well as ferrets, mice, badgers and otters. It 
also re-infects populations of wild birds, particularly 
waterbirds. As of March 2006, HPAI has caused die-offs of 
waterbirds in 30 countries in Asia, Europe and Africa, and may 
threaten endangered populations as well as contribute to the 
spread of the virus along migratory routes.

Scientific information on HPAI remains scarce. Details, including 
information on its virulence, adaptability, contagiousness, and 
dissemination through wild birds, are lacking. Conservation 
organizations and multilateral environmental agreements such as 
CMS, AEWA and the Ramsar Convention on Wetlands of International 
Importance caution against a biased public perception of the role 
of waterbirds in spreading the virus. Advocating enhanced 
scientific cooperation and awareness campaigns, they encourage the 
international community to focus on the ecological, social and 
economic causes of spreading such as the drastic reduction of 
wildlife habitats and unsustainable farming practices, arguing 
that these have led to an unnatural proximity of migratory birds 
and domesticated animals.

SCIENTIFIC TASK FORCE: CMS, in close cooperation with AEWA, 
initiated a Scientific Task Force on Avian Influenza and Wild 
Birds in August 2005. This Task Force aims to ensure that 
international efforts to contain HPAI do not overlook vital 
information concerning migratory species and other environmental 
considerations. The Task Force is comprised of representatives 
from UNEP, CMS, AEWA, Ramsar, BirdLife International, the 
International Council for Game and Wildlife Conservation (CIC), 
Wetlands International, the Wildlife Conservation Society and the 
Zoological Society of London, with the UN Food and Agriculture 
Organization (FAO), WHO and the World Organization for Animal 
Health (OIE) participating as observers. The Convention on 
Biological Diversity (CBD) joined the Task Force in March 2006. 
The Task Force has produced advice, widely circulated in the form 
of press releases, to raise the awareness of the international 
community on HPAI’s effects on wildlife, and to stress how this 
phenomenon is both a human health concern and a conservation 
issue.

AEWA MOP-3: The third Meeting of the Parties to AEWA met from 
23-27 October 2005 in Dakar, Senegal. Participants adopted 
Resolution 3.18, which calls for, inter alia: urgent responses to 
the spread of HPAI including the development of national 
surveillance schemes and contingency planning, involving immediate 
and long-term measures; increased focus on education and awareness 
programmes and capacity building, particularly in Africa; 
increased cooperation between relevant bodies; and additional 
scientific research. 

MEETING ON AVIAN INFLUENZA AND HUMAN PANDEMIC INFLUENZA: This 
meeting was held from 7-9 November 2005 in Geneva, Switzerland and 
was co-sponsored by WHO, FAO and OIE. Participants identified key 
steps to be taken to contain the spread of HPAI, including source 
control, surveillance, rapid containment, pandemic preparedness, 
integrated country plans, and communications.

RAMSAR COP-9: The ninth Conference of the Parties to the Ramsar 
Convention was held from 8-15 November 2005 in Kampala, Uganda. 
Participants adopted Resolution IX.23, which calls for fully 
integrated approaches, at both national and international levels, 
to address HPAI by bringing ornithological, wildlife, and wetland 
management expertise together with those traditionally responsible 
for public health and zoonoses. It emphasizes that destruction or 
substantive modification of wetland habitats with the objective of 
reducing contact between domesticated and wild birds may 
exacerbate the problem by causing further dispersal of infected 
birds. 

CMS COP-8: The eighth Conference of the Parties to CMS convened 
from 20-25 November 2005 in Nairobi, Kenya. Participants adopted 
Resolution 8.27, which calls for support and capacity building for 
research related to disease processes in migratory bird species, 
long-term monitoring of their movements and populations, and rapid 
development of surveillance programmes for HPAI in populations of 
wild birds. An Annex to the Resolution lists key research needs 
related to the spread of HPAI in relation to migratory birds and 
their habitats.

The AEWA, Ramsar and CMS Resolutions all support the conclusions 
of the WHO, FAO and OIE that attempts to eliminate HPAI in wild 
bird populations through lethal responses such as culling are not 
feasible and may exacerbate the problem by causing further 
dispersal of infected birds.

INTERNATIONAL PLEDGING CONFERENCE ON AVIAN AND HUMAN INFLUENZA: 
This event, held from 17-18 January 2006 in Beijing, China, was 
co-sponsored by the Government of China, the European Commission 
and the World Bank. During this event the international community 
pledged US$ 1.9 billion in financial support and discussed 
coordination mechanisms. Participants adopted the Beijing 
Declaration, in which they commit themselves to effective 
development and implementation of integrated national action 
plans, long-term strategic partnerships, information sharing, 
increased cooperation on global research, and periodic evaluation 
of national pandemic influenza preparedness and action plans.

CBD COP-8: The eighth Conference of the Parties to the Convention 
on Biological Diversity (CBD) was held in Curitiba, Brazil from 
20-31 March 2006. A brainstorming session on HPAI preceded the 
meeting. Participants at this session: highlighted threats to 
migratory species and wetlands, knowledge gaps and the need for 
capacity building; welcomed the participation of the CBD in the 
Scientific Task Force on Avian Influenza; and suggested that CBD’s 
Subsidiary Body on Scientific, Technical and Technological Advice 
(SBSTTA) further assess the interlinkages between ecosystems and 
health on matters including climate change and avian flu. 
Participants adopted a Decision on Avian Flu (UNEP/CBD/COP/8/L.35), 
in which they take note of the brainstorming meeting report and 
encourage similar consultations as and when emerging issues that 
may impact CBD implementation arise.

6TH INTERNATIONAL SYMPOSIUM ON AVIAN INFLUENZA: This event was 
held from 3-6 April 2006 in Cambridge, UK. Participants addressed 
lessons learned from recent outbreaks in Asia, Africa and Europe 
and recent epidemiological and virological information. They 
identified short- and long-term needs, including enhanced 
scientific information, cross-sectoral and international 
cooperation, and improved awareness among decision makers and the 
general public.

REPORT OF THE SEMINAR

The two-day Scientific Seminar on Avian Influenza, the Environment 
and Migratory Birds opened on Monday 10 April 2006 at UN Office in 
Nairobi, Kenya. The Seminar was chaired by Peter Schei, Director 
of the Norwegian Fridtjof Nansen Institute and Chair of BirdLife 
International.

Delegates heard 21 expert presentations on issues relating to 
avian influenza, which were addressed during four sessions: 
epidemiology and human aspects of avian influenza; avian influenza 
and wild birds; early warning systems and development of risk 
assessment models; and outcomes of recent initiatives and national 
and regional case studies. On Monday and Tuesday, discussions were 
held to formulate the Seminar’s conclusions and recommendations. 
These were finalized during a roundtable on Tuesday afternoon. 

Consensus was achieved on a large number of recommendations, 
including on: surveillance, early warning and risk assessment; 
priority short-term needs; longer-term needs; collaboration and 
cooperation; and next steps. Delegates expressed strong commitment 
to work cooperatively towards developing effective mechanisms to 
contain the spread of highly pathogenic avian influenza (HPAI).

FORMAL OPENING AND INTRODUCTION

Seminar Chair Schei opened the meeting on Monday morning.

Robert Hepworth, Executive Secretary of the Convention on 
Migratory Species of Wild Animals (CMS), outlined the work of the 
CMS-led Scientific Task Force on Avian Influenza and Wild Birds, 
which was established in August 2005 to address the emerging issue 
of highly pathogenic avian influenza (HPAI) in relation to wild 
birds. Noting that the Task Force currently unites 13 UN bodies, 
wildlife treaties and specialist non-governmental organizations 
(NGOs), he said its aims are to generate advice on the root causes 
and conservation impacts of HPAI, assess the role of migratory 
birds as vectors of the virus, and develop early warning systems 
and expertise. 

Hepworth called for a balanced, science-based approach that takes 
into account the potential role of human movements and 
unsustainable and unhygienic poultry husbandry practices and 
trade. He drew attention to resolutions recently adopted by the 
Agreement on the Conservation of African-Eurasian Migratory 
Waterbirds (AEWA), the Ramsar Convention on Wetlands of 
International Importance, CMS and the Convention on Biological 
Diversity (CBD), noting that these recommend: higher standards and 
biosecurity measures in poultry; integration of expertise on wild 
birds and conservation into animal and human health considerations; 
national contingency plans and public awareness campaigns; and 
avoidance of ineffective or counter-productive “quick fixes,” such 
as culling wild birds and destroying their habitat, which may 
induce the spreading of infected birds and thus exacerbate the 
problem.

Hepworth identified the Seminar’s objectives to: stimulate debate 
on the role of wild birds in transmitting the virus; provide 
up-to-date status reports and advice for decision-makers; increase 
awareness of the recent multilateral environmental agreement (MEA) 
resolutions among all governments; promote further research on 
virus behavior and transmission; and encourage international 
technical cooperation and risk mitigation.

Bert Lenten, AEWA Executive Secretary, said when H5N1 spread into 
the AEWA region in 2005, HPAI became a top priority for AEWA. 
Noting that AEWA was the first MEA to adopt a resolution on HPAI, 
he said the main challenge is to disseminate more balanced 
information to all relevant stakeholders. He expressed hope that 
the Seminar would strengthen cooperation between the main players, 
gather the latest scientific information and communicate it to the 
outside world through concrete recommendations, including on an 
early warning system. 

Marion Cheatle, UN Environment Programme (UNEP) Division of Early 
Warning (DEWA), observed that her Division’s early warning system 
raises awareness of emerging long-term environmental threats and 
facilitates the development of early warning measures. She stated 
that DEWA bridges the gap between science and policy by providing 
an understanding for decision makers of issues emanating from the 
science domain.

Chair Schei highlighted different dimensions of the HPAI issue, 
including the human health, animal health, agricultural, trade, 
and ecological dimensions. He expressed hope that the Seminar 
would produce up-to-date scientific information and underscored 
the need to identify knowledge gaps. Calling for short-term 
surveillance mechanisms to identify the species that contribute to 
the spread of HPAI and trade impacts, he called for an enhanced 
cooperation system.

EPIDEMIOLOGY AND HUMAN ASPECTS OF AVIAN INFLUENZA

Addressing the epidemiology of avian influenza viruses, Anja 
Globig, German Federal Research Institute for Animal Health, said 
avian influenza viruses are highly adaptable and genetically 
labile. Noting that simultaneous infection with two or more virus 
subtypes can lead to genetic reassortment, and thus to new 
strains, she said wild birds constitute a large pool of virus 
subtypes that are usually low-pathogenic. She noted that wild 
birds infected with low-pathogenic avian influenza (LPAI) 
transport and excrete the virus, and thus may infect poultry. Upon 
infection of new hosts, particularly those housed in high 
densities, the virus may evolve rapidly and mutate into highly 
pathogenic viruses such as H5N1. 

Noting that susceptibility to H5N1 differs among bird species, 
Globig said ducks may excrete HPAI without showing symptoms. She 
said the current outbreak of HPAI, subtype H5N1, differs from that 
of earlier HPAI outbreaks with respect to the first-time 
persistence of HPAI in wild birds, its wide geographic 
distribution, and its tendency to cross the species-to-species 
barrier. Globig concluded that H5N1 might be widely distributed in 
waterbirds, but that prevalence, mortality and contagiousness seem 
to be low. 

Vincent Martin, UN Food and Agriculture Organization (FAO), 
addressed the role of poultry production systems in the spread of 
H5N1 and cultural and trade practices that influence the emergence 
of HPAI. He explained that the emergence of HPAI in Asia resulted 
from the convergence of different risk factors, such as the 
increasing intensity of poultry production systems, low 
biosecurity, and the absence of effective veterinary services.

Martin highlighted the role of free-ranging duck farming systems 
in Vietnam in spreading the virus, noting that ducks foraging in 
paddy fields during the rice harvest regularly come into contact 
with wild birds and thus constitute a biosecurity risk. He also 
addressed the risk posed by backyard poultry systems. Highlighting 
that mixing of domestic species enables virus genetic 
reassortment, and thus the emergence of more virulent viruses, he 
underscored the need to improve biosecurity.

Martin identified legal and illegal international trade in poultry 
and poultry products as important risk factors for spreading the 
virus. Addressing “wet markets,” where live animals are often sold 
in conditions offering low biosecurity in addition to close 
contact between species, and highlighting the high risk of 
infection from slaughtering and consuming blood products, Martin 
called for improved risk strategies. Addressing cultural practices 
that facilitate the spread of the virus, he underscored the need 
for education in the safe handling of poultry and for 
strengthening and empowerment of veterinary services.

Christianne Bruschke, World Organization for Animal Health (OIE), 
discussed measures to eradicate HPAI at its source. She 
highlighted the significant social and economic consequences of 
the current outbreak, including the culling of over 200 million 
domestic birds. As prerequisites for effective early warning she 
identified: early detection through broad awareness and high-
quality veterinary services; rapid and transparent notification 
through an appropriate national chain of command combined with 
compensation for farmers; and rapid response through confirmation 
of suspects, confinement, humane culling, and the use of high-
quality vaccination when available and appropriate.

Highlighting cooperation between OIE, FAO and the World Health 
Organization (WHO), Bruschke called for: support for affected 
countries unable to mobilize the necessary resources; 
restructuring of livestock sectors and veterinary services, 
particularly in developing countries; and capacity building, 
including for policy makers and the private sector. She concluded 
that HPAI control should focus on poultry rather than wildlife. 

Addressing the human health dimension of HPAI, subtype H5N1, 
Honoré Meda, WHO, explained that co-circulation of human and avian 
viruses may result in virus reasssortment, mutation, and 
ultimately a pandemic resulting from humans’ lack of immunity to 
new viruses. He said that of the 160 human H5N1 infections to 
date, 85 had resulted in fatalities, and clarified that human 
infections may occur through: contact with respiratory secretions, 
faeces, contaminated feathers or blood; environmental 
contamination; and consumption of raw poultry.

Meda elaborated on the WHO alert phase approach to the pandemic 
threat, which follows epidemiological triggers, noting that 
human-to-human transmission is an important trigger. He also said 
that subsequent phases are associated with progressively higher 
levels of alertness and that recommended actions vary according to 
the phase. He explained that the current pandemic alert phase is 
characterized by no or very limited human-to-human transmission.

Discussion: During the ensuing discussion, participants addressed 
the risks related to farming methods whereby domestic birds forage 
on agricultural land. They noted difficulties in establishing 
exact statistics on prevalence of the virus in living birds, as 
well as on mortality.

Noting that livestock sector structure and veterinary practices 
differ between countries, one participant enquired whether to 
favor a standard or a case-by-case approach. FAO and OIE both 
supported tailor-made solutions in combination with general 
guidelines.

Addressing a question on preventive measures, Bruschke highlighted 
the importance of preparedness, establishing compensation 
mechanisms and upgrading veterinary services and laboratory 
facilities, and stressed that OIE’s current early warning system 
addresses all important zoonoses, not only HPAI. She said OIE 
standards recommend trade restrictions only in case of domestic 
bird infection, noting that individual countries may impose 
stricter regulations.

On intra-species virus transmission, Chair Schei stressed the need 
for species-specific information and responses. Several 
organizations called for concrete steps to incorporate wildlife 
early warning systems into the Global Livestock Early Warning and 
Response System (GLEWS) operated by WHO, OIE and FAO, noting that 
effective reporting on wild birds is currently lacking in many 
countries. Martin called for an information system, building upon 
GLEWS, that integrates data from different sources, including wild 
bird monitoring institutions. He proposed a signed agreement 
between relevant organizations, including conservation 
organizations, to integrate efforts regarding risk assessment and 
early warning.

On the likelihood of HPAI being transported by wild birds, 
participants named examples of outbreaks that were definitely 
related to bird migration, highlighting geographic and genetic 
evidence. Chair Schei noted that genetic information could play an 
important role in identifying potential roots of and linkages 
between outbreaks. One participant said the recent outbreak in 
Nigeria had been traced back to illegal poultry imports and called 
for technical and material support for developing countries.

On human infection, participants discussed contamination of water 
as one of the mechanisms of transmission and called for guidelines 
to prevent infection. On the virus’ ability to survive in the 
environment, Globig said information is inconsistent, but noted 
that H5N1 is believed to be able to survive in cold water for up 
to a month.

AVIAN INFLUENZA AND WILD BIRDS

Taej Mundkur, Wetlands International, gave an overview of the 
chronology of the H5N1 epidemic in birds since its emergence in 
Hong Kong in 1996. Recalling that 6500 birds died in Qinghai Lake, 
Central China, in May 2005, he highlighted the difficulty in 
gathering information in this remote region. He explained that 
with regard to HPAI outbreaks, three types of wild birds can be 
classified according to their feeding habits: scavenging species, 
such as crows, magpies and raptors, that are likely to forage 
around poultry farms; species such as herons, egrets and gulls, 
that often feed and scavenge solitarily in polluted water bodies 
near towns and farms; and colonially-nesting or flocking 
waterbirds that feed in farmlands or adjacent water bodies.

Noting the lack of information regarding the susceptibility of 
species to H5N1, he called for additional research, including on 
non-waterbirds. Lamenting the lack of information about the 
ability of birds to carry the virus over long distances, Mundkur 
noted that none of the five species found infected in Qinghai Lake 
were found dead outside their breeding grounds and stressed that 
only six out of 13,000 apparently healthy waterbirds that were 
tested in China were found positive for H5N1.

David Stroud, UK Joint Nature Conservation Committee (JNCC), 
presented on the complexity of bird migration systems and 
resulting problems with regard to prediction. He explained that 
public perception of wild bird migration movements has been 
confused by the simplistic representation of flyway maps in the 
media. Stroud elaborated on factors such as “leapfrog migration,” 
moult migration and the fact that species’ migration strategies 
can vary according to age, sex, weather and season, noting that 
these factors hamper prediction. He also highlighted the high 
degree of individual migration variation within bird species, but 
noted that some birds travel along defined paths and can be easily 
tracked using satellite systems. He called for enhanced 
communication with decision makers, accessible information 
resulting from ringing data, particularly regarding high-risk 
species, and efforts to conduct waterbird counts in months other 
than January.

Jan Veen, Wetlands International, presented on his organization’s 
preliminary assessment of ornithological data relevant to the 
spread of HPAI in Europe. Noting that criteria for identifying 
high-risk species include the occurrence of LPAI, contact with 
domestic birds and species occurrence, he said categorization is 
arbitrary and country-specific, but identified the Mallard and 
Black-headed Gull as high-risk species throughout Europe. 
Stressing that data on high-risk species’ migration routes and 
concentration and mixing sites are scarce, Veen said the Baltic, 
Black and Caspian Seas are main gathering sites. He elaborated on 
a wetland-specific rapid assessment planning format, developed in 
cooperation with wetland managers, that describes: wetlands’ 
topography; occurrence of vulnerable species; local and large-
scale waterbird movements; human activities; proximity of poultry 
farms; and measures to be taken in case of an outbreak.

Leon Bennun, BirdLife International, said HPAI outbreaks have 
largely been scattered and self-limiting. He stressed that the 
direct impact of HPAI on bird populations is much smaller than the 
indirect impact, which mainly results from negative public 
perception. Highlighting flawed risk assessment, panic and 
misperception induced by media and authorities, and confusion 
between HPAI and a human pandemic, he said counter-productive 
responses include culling, wetland destruction, nest destruction, 
and dumping of pets. He said some authorities are encouraging 
hunting to combat HPAI while others ban it for the same reason, 
and noted that the potential effects of banning hunting and wild 
bird trade are unclear. He said NGOs can play an important role 
through their surveillance networks and by providing data and 
expertise, disseminating information on sites and species, 
providing access to a network of expertise, and dealing with 
public misperceptions. 

EARLY WARNING SYSTEMS AND DEVELOPMENT OF RISK ASSESSMENT MODELS

Marion Cheatle, UNEP-DEWA, said the Third International Conference 
on Early Warning, held from 27-29 March 2006 in Bonn, Germany, had 
identified HPAI as an emerging hazard that requires immediate 
attention. Identifying risk awareness, monitoring, information 
dissemination and capacity as essential elements of early 
warnings, she highlighted UNEP’s activities with regard to 
monitoring of, and issuing warning on, emerging threats, and said 
human-induced environmental change is a root cause of increasing 
human vulnerability to hazards. Recalling the UNEP Governing 
Council’s call for improved cooperation between health and 
environment organizations, she underlined UNEP’s role in 
catalyzing early warning processes, filling data gaps, 
coordinating data from global earth observing systems, building 
capacity for surveillance, and raising public awareness. 

William Karesh, Wildlife Conservation Society (WCS), addressed 
early warning systems for animal-transmissible diseases, 
highlighting the Global Avian Influenza Network for Surveillance 
(GAINS), the WCS Field Veterinary Programme, and the WCS 
initiative “Animal Health for Environment and Development” 
(AHEAD). Stressing the need to avoid speculation on cause-and-
effect relationships with regard to HPAI outbreaks, he elaborated 
on the risks of species mixing at markets, cock fighting, and 
global trade in wildlife, which he said is still poorly monitored. 
Commending the concept of “one world, one health,” he encouraged 
MEAs to contribute, and human, wildlife and livestock health 
organizations to work together to link field and laboratory work, 
create accessible databases, and disseminate information. 

Ward Hagemeijer, Wetlands International, presented options for an 
early warning system for HPAI in wild birds. He stated that an 
early warning system should function as a strategic tool to avoid 
dramatic impacts and elaborated on different components of early 
warning, including sampling. He said the cost implications of 
sampling are high in situations where prevalence is low, 
highlighting that only six out of 13,000 birds tested positive for 
the virus in China. He underscored the importance of establishing 
baseline data and the possibility of using sentinel birds – virus-
negative birds that are closely monitored – to ascertain the 
prevalence of the virus. Stressing the need for capacity building 
for sampling, he called for enhanced cooperation between existing 
initiatives. 

Hagemeijer mentioned constraints relating to transporting samples 
and acquiring permits to take samples across borders He called for 
enhanced strategies to facilitate the exchange of samples and 
highlighted the importance of reporting as a component of an early 
warning system to trigger actions and allow effective decisions 
and responses. He described follow-up actions such as rapid 
assessment missions to enable local authorities to coordinate an 
effective response. He elaborated on NEWFLUBIRD, a potential early 
warning system model for western Eurasia and Africa, which could 
also function as a regional component of GAINS.

Addressing risk assessment models for the spread of HPAI, 
Katharina Stärk, Swiss Federal Veterinary Office, gave an overview 
of international standards in risk assessment and the current 
status of risk assessment in relation to H5N1. She explained that 
risk analysis offers a structured approach to synthesizing all 
available information to support objective, science-based decision 
making, and comprises of risk management, risk assessment and risk 
communication. She added that risk management is the driving 
force. Calling for a global framework for HPAI-related risk 
assessment, Stärk noted that knowledge gaps hamper risk assessment 
and called for a focus on relative risk rather than on absolute 
risk. She affirmed risk assessment as an effective approach and 
added that global risk assessment requires information sharing and 
consideration of incentives rather than penalties.

Discussion: In the ensuing discussion, participants addressed 
options for the management of HPAI in wild birds after an 
outbreak. They stressed the need to avoid panic, considering that 
most outbreaks are minor and self limiting. Calling for a long-
term, globally coordinated approach, participants recognized that 
other communicative diseases should be addressed simultaneously. 

Participants expressed concern about government policies that 
promote culling of wild birds, including in Russia and the 
Philippines, and called upon the CMS-led Scientific Task Force to 
send appropriate signals to governments.

Participants called on UNEP to liaise with the Convention on the 
International Trade in Endangered Species (CITES) to address 
transboundary transportation of wildlife samples, as well as 
possible sanctions for killing migratory species or for allowing 
poultry diseases to contaminate the environment.

On Tuesday morning, participants were invited to comment on the 
Seminar’s draft outcome document and propose amendments. One 
participant highlighted the need to address national-level 
reporting in the context of a global-level early warning system. 
Discussing the issue of compensation, participants highlighted 
developing country constraints, expressed the urgent need to 
encourage farmers to report outbreaks in a timely manner, and 
called on donors to compensate farmers directly. Compensation was 
also proposed for national parks that lose revenue due to HPAI 
control measures, with one participant noting that protected areas 
in Asia have already been affected. Martin clarified that FAO is 
currently examining the compensation issue.

OUTCOMES OF RECENT INITIATIVES AND NATIONAL AND REGIONAL CASE 
STUDIES

On Tuesday, David Rapport, EcoHealth Consulting, addressed 
linkages between the threat of an HPAI pandemic and the 
environment. He noted increasing evidence that many human health 
crises, including the HPAI pandemic threat, are related to human-
induced ecosystem degradation. Describing human health as a 
function of ecosystem health, he said the “ecohealth perspective” 
is gaining wide acceptance, noting that it recognizes that: 
indicators of ecosystem health include functionality, vitality and 
resilience; deterioration of ecosystem health results from chronic 
exposure to anthropogenic stresses; highly degraded ecosystems may 
not recover, even if stress loads are lessened; loss of ecosystem 
health places humans at risk; and addressing these issues is a 
matter of politics rather than science.

To reduce cumulative stresses, Rapport advocated an upstream 
approach through: adopting a mixed strategy that addresses both 
human health and ecosystem functioning; phasing out existing, 
high-risk farming practices; reducing close contact between 
humans, poultry and wildlife; maintaining and restoring wetlands; 
and protecting flyways from conflicting land uses. 

Reinhard Lentner, Directorate-General (DG) Environment, European 
Commission (EC), described his DG’s actions regarding HPAI. 
Describing the collaboration between different EU bodies involved 
with HPAI, he advocated multidisciplinary problem-solving and 
strong involvement of ornithological experts. He said the EC works 
closely with the European Member States to develop an EU-wide 
response and biosecurity strategies. On implications for wild bird 
conservation, Lentner highlighted the EU Birds Directive, which 
provides for protection of wild birds and regulation of hunting. 
He underscored the EC’s position on culling, which is that it is 
neither advisable nor justifiable, has little scientific support, 
and may facilitate the spread of the virus. He said hunting is now 
prohibited in areas of outbreaks and live decoys are banned in 
high-risk areas.

Lentner said his DG and conservation authorities cooperate closely 
to generate advice and ensure sufficient monitoring and 
surveillance of wild birds, and identified future needs, including 
increased understanding of virus behavior in wild birds and 
improved wild bird surveillance and information and awareness 
strategies.

Addressing FAO’s activities on wild bird surveillance in Africa, 
Vincent Martin, FAO, said that FAO, with support from other 
partners, initiated five regional technical cooperation programmes 
(TCPs) in November 2005 as a proactive response to HPAI. He noted 
that these programmes aim to enhance local knowledge and capacity 
with regard to epidemiology, wildlife surveillance and laboratory 
diagnostics. 

Martin discussed the West African TCP, which focuses on the 
Senegal, Niger and Chad River basins for active surveillance using 
a quick risk assessment process. He noted that as these river 
basins are significant wetlands with large congregations of wild 
birds in proximity to poultry, they are potential sites for the 
introduction of the H5N1 virus into West Africa.

Observing that H5N1 was not detected in 3500 samples taken in 
Chad, Mali, Ethiopia and Morocco, Martin highlighted the 
constraints of wild bird surveillance noting that it is resource 
intensive. He called for training in capture and sampling 
techniques in addition to collaboration within different 
government departments.

Martin emphasized the need to analyze surveillance results, review 
surveillance protocols and enhance understanding of migratory 
patterns within Africa, including through ringing and examining 
wetlands dynamics as environmental triggers for migration.

Ahmed Djoghlaf, CBD Executive Secretary, presented the outcomes of 
the CBD brainstorming meeting on HPAI held prior to the eighth 
Conference of the Parties (COP-8) to CBD in March 2006, and the 
resulting COP-8 Decision on Avian Flu (UNEP/CBD/COP/8/L.35). He 
addressed the impact of HPAI on wildlife and lamented the lack of 
knowledge on the issues, particularly in Africa. With regard to 
the impact of HPAI on livelihoods and development, he highlighted 
the implications of HPAI for attaining the Millennium Development 
Goals. Stressing that it is fundamental to examine HPAI in 
relation to both wildlife and livelihoods, he underscored the 
close relationship between ecosystem health and human health. He 
called for capacity building in Africa, enhanced public awareness 
and education, and inter-agency cooperation, including through the 
potential establishment of a broader task force.

David Stroud, JNCC, presented outcomes of the 6th International 
Symposium on Avian Influenza, held from 3-6 April 2006 in 
Cambridge, UK. Highlighting Asian experiences, he reported that 
vaccination in parallel with other control measures has proven to 
be effective. Addressing the current situation in Nigeria, Stroud 
noted the conclusions that: the poultry sector is Nigeria’s second 
largest industry after oil; genetic evidence reveals separate H5N1 
introductions; and laboratory work has shown that the 
vulnerability of ducks to H5N1 is age- and strain-dependent. 
Addressing experimental infections of different wild bird species, 
Stroud noted varying vulnerabilities and added that the level of 
an initial viral challenge is critical to whether or not a bird 
develops symptoms. He highlighted a European response task force 
that was established in response to previous outbreaks of H7 
subtypes in Europe. 

Stroud drew attention to reports that H5N1 survival in the 
environment depends on salinity and temperature and is lower than 
that of other H5 and H7 subtypes. He concluded that the Symposium 
acknowledged: the enormous social and economic impact of poultry 
outbreaks and the importance of prevention; the frightening 
pathology of H5N1, including rapid neurological effects; the 
dangers of asymptomatic virus carriage by ducks; and the need for 
better information on the virus’ environmental persistence.

Evgeny Kuznetsov, all-Russia Research Institute for Nature 
Protection, addressed the recent spread of H5N1 in Russia. He said 
initial patterns suggested a relationship with bird migration from 
China, while recent developments revealed a significant 
contribution by human traffic along roads and railroads. Noting 
that his Government’s official report on the initial outbreak in 
July 2005 lacks sound data, he said authorities are promoting 
culling of wild birds as a viable option to contain the outbreak. 
He described how special forces kill wild birds around villages 
and poultry farms, which he said is leading to increased bird 
dispersal and an added risk of local infections. Kuznetsov said 
regular hunting has now been banned, which stimulates poaching and 
results in food scarcity among subsistence hunters, and 
highlighted attempts to poison birds, including non-waterbirds. 
Proposing ways to improve monitoring, he recommended increased 
ringing activities and following individual birds along flyways to 
study patterns in virus prevalence, virulence and survival. 

Richard Kock, Zoological Society of London, addressed the notable 
absence of HPAI in the East-African Great Rift Valley. He stated 
that the occurrence of outbreaks is related to epidemiology and 
geography rather than to human control efforts, noting that the 
deserts of Northern Africa and the Middle East seem to constitute 
effective barriers to virus dispersal. He said the risk of 
spreading of HPAI into the Great Rift Valley is extremely low, 
given the small percentage of waterbirds that migrate to this 
region and the limited chance of infected birds being able to 
cross the desert barrier. Stressing the importance of establishing 
baselines and conducting longitudinal studies, Kock recommended 
establishing monitoring stations in the main flyway corridors and 
linking such efforts with current ringing activities and long-term 
ornithological studies.

Discussion: During the ensuing discussion, one participant 
suggested extending TCP activity to South-East Asia, considering 
the urgent need to improve surveillance of wild birds in this 
region. 

Participants discussed ecological sanitation of wetlands and 
methodologies for designing surveillance schemes and the 
parameters required. Underlining the role of protected areas in 
public awareness and education, one participant called for 
government action to avoid socio-economic consequences of HPAI 
control measures in protected areas.

Discussion also focused on follow-up strategies regarding the 
Seminar’s outputs, with the CMS-led Scientific Task Force being 
suggested as the most suitable mechanism for coordinating 
activities. Some participants urged further examining the 
relationship between trade and HPAI, suggesting the expansion of 
the Task Force with a commodity specialist to study the relevant 
market implications.

ROUNDTABLE DISCUSSION

A roundtable session was held on Tuesday afternoon, bringing 
together Seminar participants, UNEP Country Permanent 
Representatives and the media. David Stroud, JNCC, presented an 
introduction to the issue and a preliminary overview of the 
Seminar’s outcomes and recommendations, addressing: surveillance, 
early warning and risk assessments; priority short-term needs; 
longer-term needs; collaboration and cooperation; and next steps.

One participant stressed the need for a holistic perspective 
taking into account issues relating to improving livelihoods and 
eradicating poverty. He stressed the need for capacity building in 
all sectors, particularly in Africa. Another participant called 
for political will to integrate ecosystem and human health 
concerns, lamenting the prevailing focus on economic growth as a 
prerequisite for human well-being. 

Several participants described national experiences with HPAI 
contingency plans, noting the importance of effective coordination 
between different government departments and between governments 
and NGOs. There was a general call for improved coordination 
between neighboring countries to enable transboundary contingency 
planning.

Participants addressed the need to assign national lead agencies 
for coordinating contingency planning, concluding that each 
country should decide individually which lead agency to appoint. 
They stressed the need for long-term surveillance schemes. 

Vincent Martin, FAO, observed that Niger had taken limited control 
measures to contain HPAI and had only just begun to cull poultry, 
but clarified that the virus is not spreading as quickly in Africa 
as it has in Asia. He attributed this restrained progression to 
the dry and hot Sahel climate, but cautioned that this situation 
could change during the raining season. He also highlighted the 
Pan African Programme for the Control of Epizootics (PACE), an 
early warning and control system which also addresses HPAI, noting 
that FAO works in close collaboration with this Programme and 
provides assistance. He added that rapid assessment teams would be 
established to help countries strengthen their surveillance 
capacities.

Christianne Bruschke, OIE, reaffirmed that HPAI is only a 
“notifiable disease” in poultry, not in wildlife. Noting factors 
that prevent some countries from fulfilling their notification 
requirements, she elaborated on a joint mechanism with FAO to pool 
all reported information and input from rapid assessment teams to 
inform other countries about the risk of contracting HPAI.

With regard to UNEP’s role in the Scientific Task Force, Norberto 
Fernandez, UNEP-DEWA, and Robert Hepworth, CMS Executive 
Secretary, highlighted UNEP’s experience in assessing the state of 
the environment as well as its extensive network and expertise. 
They also highlighted UNEP’s role in facilitating meetings, 
providing scientific information, and disseminating advice 
relating to culling and wetland destruction.

Participants also addressed the feasibility of using regional 
economic organizations such as the Economic Community Organization 
of West African States (ECOWAS) to facilitate workshops and 
seminars for public awareness raising. Vincent Martin, FAO, 
highlighted three awareness-raising workshops held in Africa.

Participants then discussed the draft conclusions and 
recommendations of the Seminar. Discussions focused on the need 
to: develop, in collaboration with FAO, mechanisms to restructure 
agricultural production systems with the goal of reducing stresses 
on ecosystems and risks to human health; strengthen the Scientific 
Task Force through additional financial resources and the 
appointment of a full-time Scientific Task Force Coordinator; and 
review the terms of reference and membership of the Scientific 
Task Force, consider its future priorities, and examine potential 
cooperation with and support from other bodies.

FINAL CONCLUSIONS AND RECOMMENDATIONS

On Tuesday afternoon, participants reached consensus on and 
finalized the Seminar’s conclusions and recommendations. The 
following is a brief summary of this outcome document.

In an introductory section, participants recall the establishment 
of the CMS-led Scientific Task Force on Avian Influenza and Wild 
Birds. They also recall the recent conclusions of the Contracting 
Parties to AEWA, Ramsar and CMS, which state that HPAI, subtype 
H5N1, is considered to have spread between countries by many 
different vectors, including through the movement of avian 
livestock and migrating waterbirds, and that evidence of causal 
links is often lacking. Participants stress that the establishment 
and maintenance of high standards of poultry biosecurity remains 
central to the reduction of infection risk, and that national 
veterinary services should be upgraded to OIE standards.

In a section on surveillance, early warning and risk assessments, 
participants state that early detection is essential for the 
control or eradication of HPAI, subtype H5N1. They note the 
considerable efforts of FAO, WHO and OIE to develop an integrated 
early warning system and underline the need to build upon existing 
initiatives. They stress the importance of ensuring adequate 
surveillance and rapid reporting and data-sharing systems, and 
specify that surveillance programmes should: be web-based; 
facilitate integrated responses and risk management; report 
associated meta-data that allow full analysis of the results; and 
facilitate timely and effective risk management. Participants call 
for standardization of national-level reporting. On risk 
assessments, they state that all countries should undertake 
transparent, structured and science-based risk assessments and 
make use of all available knowledge. They recognize the general 
need for strengthening HPAI field surveillance, especially in 
developing countries, and for developing the capacity of 
veterinary services worldwide. On data and information needs, 
participants call for improved, contemporary and international 
analysis of existing waterbird ringing and count data at the 
species level and also in months other than January. They also 
identify the need for better consolidated information on national 
trade in poultry and poultry products. 

In a section on priority short-term needs, participants recognize 
the importance of: rapid reporting and control measures; data 
collection on trade issues, the development of compensation 
policies for agricultural losses and impacts on protected areas; 
and effective communication with the media, the public and policy 
makers using scientific facts. They call for additional research 
on: the prevalence of H5N1 in wild bird populations; existing 
ringing data to assess migratory systems; the ecology of the virus 
in the environment; natural mortality levels in wild bird 
populations; wild bird susceptibility to H5N1; and effective 
measures to reduce transmission of H5N1 between wild birds and 
poultry. 

In a section on longer-term needs, participants recognize the need 
to build programmes of sustainable financial measures and other 
support to ensure the sustainability of short-term measures. They 
recognize that ecosystem degradation has played a role in the 
evolution and spread of H5N1, and urge the development, in 
collaboration with FAO, of mechanisms to restructure agricultural 
production systems with the goal of reducing stresses on 
ecosystems and risks to human health. Participants call for better 
information on cultural practices that have the potential to 
either help or hinder the control of H5N1.

In a section on collaboration and cooperation, participants stress 
the need to develop and maintain collaborative approaches and 
partnerships that integrate wetland and wildlife management 
expertise with expertise on human health and zoonoses. They 
reaffirm the important role of the Scientific Task Force on Avian 
Influenza and Wild Birds. On data and information needs, they call 
for better integration of existing data on trade in poultry and 
other birds and the establishment of a web-based clearing-house 
mechanism on the spread of H5N1.

In a section on next steps, participants ask the Scientific Task 
Force, as a matter of urgency, to promote the implementation of 
the Seminar’s conclusions and recommendations both within 
participating organizations and among others. They suggest that a 
review of the work of the Task Force, including the Seminar’s 
conclusions and recommendations, be communicated to the UN Special 
Coordinator for Avian Influenza. They state that to maintain the 
Task Force’s professional approach, additional financial resources 
are urgently needed, and suggest the appointment of a full-time 
Scientific Task Force Coordinator. Participants ask CMS to review 
the terms of reference and membership of the Scientific Task 
Force, consider its future priorities, and examine potential 
cooperation with and support from other bodies.

CLOSING OF THE SEMINAR

Shafqat Kakakhel, Acting Executive Director of UNEP, expressed his 
appreciation to the Seminar’s co-sponsors, including the UK 
Department of Environment, Food and Rural Affairs (DEFRA), FAO and 
the Netherlands’ BirdLife partner, Vogelbescherming Nederland. He 
stressed that environmental change in combination with the 
emergence of infectious diseases is one of the greatest challenges 
of our time, noting the significant negative impacts of a degraded 
environment. He reaffirmed the need to effectively follow up on 
the Seminar’s conclusions and recommendations through tangible and 
measurable actions and called for enhanced inter-agency 
cooperation. He also reaffirmed UNEP’s commitment to disseminating 
the Seminar’s findings and managing the risks associated with HPAI.

Seminar Chair Schei commended participants for their constructive 
engagement and expressed satisfaction with the Seminar’s outcomes. 
He said proceedings of the Seminar, including summaries of all 
expert presentations, will be circulated among participants and 
become available through the CMS website. He closed the meeting at 
6:30 pm.
