In post-conflict settings, landmine and unexploded ordnance (UXO) constitute a public health hazard. In Vietnam, forty two years after the conflict has ended, people continue to be injured by the remaining of explosive remnants of war (ERW), as a resulting in long term disability, psychological sequel, and death. Mine risk education (MRE) program has become a fundamental key for effective health education and promotion in the field of mine awareness. MRE included public information dissemination, education and training and community mine action liaison in the battle area after the war. This study was adopted a mixed methods research approach which consisted of non-participant observation, survey, and in-depth interview. The findings from this study indicated both of the organization and individual levels have many positive effects and impacts. On organization level, the findings found that the MRE program was timely and satisfy the community needs in terms of reducing the threats from landmine and UXO. The finding of the study also revealed that the coordination between the MRE organization and Inter-Agency Coordination Group on Mine Action (IACG-MA) greatly supported MRE activities and initiatives within United Nations (UN) system. Meanwhile, the study indicated in terms of the impact of the MRE which based on coverage and scale perspective through how many individuals receiving the MRE training as well as coverage of risk education at contaminated areas. In addition to organization aspects, the MRE program has impacted on individual level. Both of the adults and children have remarkably gained the knowledge and the positive attitude. The questionnaire regarding the knowledge of MRE was surveyed in one of the most UXO contaminated district in Quang Nam province. In research area, 53 adults (28 teachers and 25 non-teachers) and 184 children were surveyed by KAPB; 18 participants included government state officer, village leader, international NGOs staff, landmine survivor, teachers and student who were interviewed by in-depth interview. The result of the survey noted that the major damage of UXO to human being included death and casualty. Key of risk behavior for local people consisted of tampering, fire, moving, and throwing landmine and UXO. However, the finding of KAPB illustrated that 7.2% of both teacher and non-teacher did not know the reason why a UXO exploded and 1.5% agreed that they should take the UXO and throw it away. The result showed that 1.1% of children respondents did not know how to protect themselves from landmine and UXO accident. As a result, the study indicated a need so as to integrate the MRE into the curriculum and encourage stakeholders in order to improve the effects and enhance the quality of MRE programs.
