One Health and Ecohealth: A framework for agriculture and health research and intervention
1. One Health and Ecohealth:
A framework for agriculture and health
research and intervention
Hung Nguyen, Fred Unger, Jeff Gilbert, Delia Grace
ILRI@40 Livestock and healthy lives workshop
Addis Ababa, 7 November 2014
2. Complex health problems - need of new approaches
• Complex interaction of disease emergence and
environmental factors
• Needs strong capacity to respond to current and
future challenges of emerging infectious diseases and
other health issues.
• One Health and Ecohealth approaches are more
effective ways to tackle the complexity associated
with emerging infectious diseases than employing a
single disciplinary approach.
3. Ecohealth
Sick animals
Zoonoses
Ecohealth framework assumes human, livestock, wildlife, and environmental
health are integrally related
6 principles (IDRC, 2012)
1. Systems Thinking
2. Transdisciplinary Research
3. Participation
4. Sustainability
5. Gender and Social Equity
6. Knowledge to Action
4. http://www.cdc.gov/onehealth
The collaborative efforts of multiple
disciplines working locally, nationally and
globally to attain optimal health for people,
animal and our environment
(FAO, OIE, WHO, WB…)
One Health
“One Health” can be defined as the added value in terms of lives of animals
and humans saved, financial savings and improved ecosystem services from
a closer cooperation of human and animal health as compared to single
sector approaches (Zinsstag et al., 2012)
From theoretical to operational definition:

• $25 billion invested would bring
benefits worth $125 billion.
• Zoonotic diseases interventions: $3.7
for every $1.0 invested.

9. One Health and EcoHealth research at ILRI
Research
– Ecosystem Approaches to the Better Management of Zoonotic Emerging
Infectious Diseases in Southeast Asia (EcoZD): Trans-disciplinary
collaboration between institutions & teams
– Cost-benefit analysis of One Health
– Food safety and One Health
Capacity development
– Ecohealth resource centres: Chiang Mai University (CMU), Thailand and
University of Gadjah Mada (UGM), Indonesia, PHFI in India, CENPHER at
HSPH
– Taskforce for food safety risk assessment
Influencing outcomes and policy
10. Ecosystem Approaches to the Better Management of
Zoonotic Emerging Infectious Diseases in Southeast Asia
(EcoZD)
General objective:
Increase the EcoHealth capacity in SE Asia
targeting the risks and impacts of Zoonotic
Emerging Infectious Diseases (ZEIDs)
and how feasible options can be best
implemented
2008 – 2013
‘Learning by Doing’ of EH approach;
also new for ILRI team
Regional: 6 countries
11. ILRI EcoZD – 6 country teams & case studies

Various institutions, Livestock Services, MoH, Universities, PhD student
Cambodia: Zoonotic Causes of Acute Bloody Diarrhoea in rural Cambodia
4 Institutes (Livestock/AH and Health)
Vietnam: Zoonoses priority ranking at Provinces in Southern Vietnam (Leptospirosis
in pigs and humans), 3 Institutes (PH and livestock)
China (Yunnan): Prevention and Control of Brucellosis & Toxoplasmosis
- 4 Institutions/Universities involved
Indonesia: Study on Rabies Control in Bali (dog ecology and behavior)
4 Institutions/NGO & 1 Universities
Laos: Study of smallholder pig system in lowland and upland
(zoonoses & production diseases), 3 institutions & 1 University

Working group
• Public Health
• Veterinarian
• Policy makers
• Community
Mode of operation
• Training
• Case study
• Policy influence

• Capacity building: One Health workforce
• Incentives: how to share credits, added
values of One Health
• Sustainability
