14 Better Human and Animal Waste Management in Hanam Province, Vietnam using Ecohealth / One Health Approach What did we think? Agricultural intensification had closed relationship with ecosystem and human health. Livestock: advantages and disadvantages Livestock waste management, reuse. Any innovative changes are needed to develop the agricultural & livestock systems to increase production, at the same time preserving and enhancing natural resources. Using ecohealth approach to manage animal and human wastes

15 What we did so far: (NCCR North-South program) 1. Community engagement (Local authorities) 2. Research ( PhD, MSc) But more focus on Diseases : Health Status, Diseases.. Focal Issue Sanitation & Health Kim Bang district, Hanam, Vietnam What do we need? Understand the real situation of Agriculture intensification Design Implement Intervention Dissemination Communicate with Stakeholders engagement Stakeholderw orkshop Issues identified Issues Researchers stay with community (none-scientists) Human, animal health & wellbeing Environment Social- economics Community engagement

16 Some research activities were carried out PRA: to identify emerging problems of local communities and issues related to agricultural and human waste managements. Baseline survey: 461 households to explore the relationship between waste management practices and rural household health status in the study sites to identify the current animal waste treatment methods Health risk assessment related to biogas-wastewater Exposure assessment: 451 pig farms; Samples: 150 Quantify the microbial and chemical indicators: E. coli, Salmonella, Giardia, Cryptosporidium, BOD & COD, ph, temperature Estimate the risk of infections and diarrhea by the specific pathogens Community-based intervention Village regulation; good practice pig farm; behavior change communication. 2/1/

17 Risks of diarrhoea related to biogas wastewater Increasing livestock production (MARD, 2013) Environmental pollution caused by livestock waste becomes more severe (Đ.T.T.Sơn, 2011) Biogas is commonly used for treatment of livestock waste (H.K.Giao, 2010) Biogas if not properly used -> the efficiently destroyed pathogens is low (V.T.Y.Phi, 2009; Jirina, 2012) Most pig farms discharge biogas wastewater direct to public drainage (79%), irrigation (43%) (L.Q.Hương, 2014) 2/1/2016

18 Dose-response models (Sources: Haas et al., 1999, Howard et al., 2006) Estimated single risks of infection Where are: Quantitative Microbial Risk Assessment (QMRA) (Hazard identification Dose-response analysis Exposure assessment Risk characterization) Exponential model (Giardia & Cryptosporidium) P inf(d) = 1 exp(-rd) β-poisson model (E. coli) P inf(d) = 1 [1+ (d/id 50 )(2 1/α 1)] -α - P inf(d) : risk of infection in an individual exposed to a single pathogen dose (d) - α: infectivity constants (E. coli: ) - ID 50 : pathogen dose at which 50% of a population will be infected (E. coli: 8.6 x 10 7 ) - r: infectivity constants (Giardia: 0.02 and Cryptosporidium: ) - d (dose ingested) = μ x m μ: concentration of organism/100ml February 1, m: 2016 amount of water accidental ingested Monday seminar 18

19 Estimated average single risk of diarrhea Irrigating vegetable Probability of diarrhea risk by E. coli (12%), Crypto (25%), Giardia (5%) Irrigating fruit tree Irrigating corn crop Cleaning drainage Maintaining biogas Estimated single risk of diarrhoea Estimated single risk of diarrhoea Estimated single risk of diarrhoea

20 Community-based Intervention Good Practice Pig-Farm (GPPF) in Vietnam Properly treatment of animal wastes by biogas system understand the biogas operation and maintenance process aware the health risks related to biogaswastewater (human & animals) Good enforcement the village regulation on environmental sanitation Effective behavior change communication Increase skills for monitoring & prevention of animal diseases Village core group members (local authority, head of village, village health workers & para-vet.; pig holders) & Researchers Decreasing the frequency exposure to biogas-wastewater Reduction of pathogens in the biogas-wastewater (E. coli, Sal) Safe use of wastewaterirrigated products (vegetables, fish) Reduce the health risks related to biogaswastewater (human, animals) 2/1/

21 Community-Based Intervention 2/1/ Good Practice Pig-farm Saving time, water, electricity, money More gas for cooking Less smell, flies Improving personal hygiene practice More friendly Increasing productivity

22 Reducing disease risks & improving food safety in smallholder pig value chains in Vietnam (PigRisk) Risk profiling 1 Project framework 2 Risk assessment Microbial Risk Assessment Chemical Risk Assessment 3 Animal Health Risk Assessment Interventions Economics (eg health, CBA) Rapid assessment Action research 1 Action research 2 Action research 3 Value chain Economic assessment. Incentive-based interventions Randomized Control Trials (RCT) 4 Engaging stakeholders and co-generating evidence, Advocacy, Communication, OM

24 Taskforce: Food Safety Risk Assessment Established a Taskforce of risk assessment for food safety: MOH, MARD, Institutes, Universities, Private Sectors... Analyses of food safety policy in Vietnam and how research evidence informs policy. Stakeholder workshops were conducted to identify the scope of activities and priority issues in food safety. Training courses and follow-up along with case studies of risk assessment for food safety were held. Developed the guidelines for risk assessment on food safety (both microbial and chemical hazards). Dissemination workshops to development of policy on food safety.

25 Capacity building Training courses for public health & veterinary professionals MOH, MARD. Developed textbooks and guidelines on food safety risk assessment. Publication of a special edition of risk assessment in a Vietnamese journal; Policy briefs developed

26 real situation of policy change Identified issues Research Results Policy Policy? makers changed accepted

27 From Evidences to Decisions Establish a working group / policy alliance group (PAG) Meetings, study site visits, dialogue, forum, etc. Mass media, communication event, linking websites Provide clear/concrete evidences, goals, targets (policy briefs) The message must be designed specifically for the policy makers to better reflect their needs The credibility of the messenger can be as important as the message itself Will & determination to move and wait for opportunities Stakeholders analysis win without fighting

28 Example: Topics to be discussed The government is developing a strategy for developing livestock production; How recommendations issued by Ecohealth/One Health project can better be in line with current discussions on the policy? How the Working Group can assist CENPHER to design the research results in a message targeting decision makers? Who can be the best messenger to present Ecohealth project and results to decision makers?

29 Moving towards a One Health approach in Vietnam MARD-MOH joint inter-ministerial circular (16) on coordinated prevention and control of zoonotic diseases (May 2013) Establishment of new DAH division on veterinary public health as well as the Emergency Operations Center located in GDPM office OH is in the national strategies Emerging Pandemic Threats activities, VAHIP, SEA-EU-NET and associated donor commitment Recognition of the need to include wildlife in animal health efforts and zoonotic risks One Health Communication Network for journalists

30 Challenges Institutional challenges: acceptance, policy engagement Capacity building: One Health Workforce Incentives: how to share credits, added values of One Health Deeper coordination between sectors on human and animal (and wildlife) health and the environmental agencies Improving the translation of evidence and research into policy

31 Summary and conclusion One Health in Vietnam - Great attention and support from different level - Training in good way, but limited research - Inter-sectoral collaboration and policies: good enabling environment Challenges and ways forward - Capacity building: One Health Workforce - More research & case studies - Deeper coordination of sectors: further (re)-organization - Resources
