A Community Participatory Intervention Model To Reduce The Health Risks From Biogas Wastewater in Hanam Province, Vietnam
INTRODUCTIONIn Vietnam, livestock production has been rapidly developing, i.e. increasing in thenumber of animals in general, and in animal size/number of households inparticular. Waste in animal livestock amounted to 85 million tons per year and 37million tons of wastewater per year (Vietnam rural agriculture, 2014). A largeamount of waste is directly disposed to the environment, causing environmentalpollution and adverse impacts on human health.
To address this situation, biogas system have applied to treat livestock waste incommonly, in particular at the smallholder farms. However, most of smallholderfarms have not yet used the biogas correctly then biogas wastewater could affecthealth and environment. We applied transdisciplinary and communityparticipatory approach (called Ecohealth approach) in research to improveknowledge and practice of farmer for better operation of biogas systems andtreatment of waste.
The transdisciplinary approach is likely to be adopted widely in the interventionprogram, particilar intervention programs to change the agriculture and ruralissues. Community priorities should be determined by local people. Thencommunity problem will be solved by knowledge of scientists and practicalexperience of local people co-operation. It is core competency of the ecosystemapproach to health.

OBJECTIVESThe 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.
RESULTSPhase 1: Develop intervention toolsIntervention 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.

METHODSIntervention studies comparing with the control group before and after wasapplied. The research sites were Hoang Tay and Chuyen Ngoai commune in Hanamprovince during 2015. In the filed, farmers lived in biogas households that wereinvited to the research as target subjects. Total of 399 participated farmers weredevided to control group and intervention group that were accounted 255 and 144,respectively. The Intervention are implemented in six months for around. Develop
interventiontools, pilot andtraining, applyingthat were maincomponents ofintervention.Core farmergroup is the keypartner thatmadesustainability ofintervention.

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