Development of Methodologies and Technology
for Supporting Clearance of Landmines and
Unexploded Ordnance in Viet Nam (January 2003)

Post-conflict areas of the world suffer from the ravages of war materiel that may remain a menace to human life long after the guns are silenced. Ecosystems necessary to support the economic framework of human settlements, are often severely damaged or obliterated by war. Communities in post-conflict areas continue to suffer the consequences of environmental degradation, and those wrought by the hidden dangers of landmines, unexploded ordnance (UXO) and chemicals.

In many areas of southern Viet Nam, landmine and UXO clearance activities may be occurring in chemically contaminated soils; of particular concern are soils contaminated by dioxins as a result of historical applications of Agent Orange herbicide. Aside from chronic exposure problems for local inhabitants, the existence of chemical contaminants can result in acute exposure risks to UXO/landmine clearance crews and support workers.

The goal of this project was to develop new methods and technologies to support mine action programs. Our approach included an integration of historical war records, satellite remote sensing data and geographical information systems (GIS) to compile and display key elements, including:
