1. A Community Participatory Intervention Model To Reduce The
Health Risks From Biogas Wastewater in Hanam Province, Vietnam
INTRODUCTION
In Vietnam, livestock production has been rapidly developing, i.e. increasing in the
number of animals in general, and in animal size/number of households in
particular. Waste in animal livestock amounted to 85 million tons per year and 37
million tons of wastewater per year (Vietnam rural agriculture, 2014). A large
amount of waste is directly disposed to the environment, causing environmental
pollution and adverse impacts on human health.
To address this situation, biogas system have applied to treat livestock waste in
commonly, in particular at the smallholder farms. However, most of smallholder
farms have not yet used the biogas correctly then biogas wastewater could affect
health and environment. We applied transdisciplinary and community
participatory approach (called Ecohealth approach) in research to improve
knowledge and practice of farmer for better operation of biogas systems and
treatment of waste.
The transdisciplinary approach is likely to be adopted widely in the intervention
program, particilar intervention programs to change the agriculture and rural
issues. Community priorities should be determined by local people. Then
community problem will be solved by knowledge of scientists and practical
experience of local people co-operation. It is core competency of the ecosystem
approach to health.

OBJECTIVES
The intervention program aimed to:
• Develop and implement a set of interventions tools by participatory of
transdisciplinary sectors.
• Improved knowledge and practices of farmer for better operation of biogas
systems and treatment of waste.
RESULTS
Phase 1: Develop intervention tools
Intervention tools package were obtained that including village law (“Huong uoc”) on
environmental protection, a guideline of 6-step program of pig cage cleaning, a health
monitoring books for humans and animals, a information calenda.

METHODS
Intervention studies comparing with the control group before and after was
applied. The research sites were Hoang Tay and Chuyen Ngoai commune in Hanam
province during 2015. In the filed, farmers lived in biogas households that were
invited to the research as target subjects. Total of 399 participated farmers were
devided to control group and intervention group that were accounted 255 and 144,
respectively. The Intervention are implemented in six months for around. Develop

CONCLUSION
• Communication by community participatory is effective
approach that made to improve properly knowledge and
practice of farmer in using biogas.
• Core group farmer is important factor of community
participatory approach.
