This is the second in a four-part series of articles on a trip by four students from Sear Rogers International School to central Vietnam to visit Oxfam Hong Kong's anti-poverty projects. The study tour was a prize for their participation in Oxfam's campaign to ban landmines. Some areas of central Vietnam are still affected by landmines, a legacy from the war with the Americans which ended more than 20 years ago. The four students - Dharam Mirpuri, Bhagyasheel Sartape, Mathew Ting and Paul Vataga - spent one week in Quang Tri province, central Vietnam. Dharam Mirpuri writes about what he learned: 'Landmines are a major problem in central Vietnam today. They are designed to disable a person and not to kill. 'Another big problem is a chemical by the name of Agent Orange. This was a chemical that was sprayed throughout the region during the Vietnam War. 'It would change the colour of all the grass, trees and plants to yellow overnight, so that the soldiers couldn't camouflage themselves and thus would be easy targets. 'Agent Orange also contaminated the rivers, lakes, streams and a lot of the wildlife. If anyone swallows anything containing the chemical, it could result in death or serious side-effects, like the birth of a deformed and disabled baby. 'We visited Mr Duc and his family who live in a village in central Vietnam. The village is seriously affected by Agent Orange and landmines. 'Mr Duc lost an arm to a landmine in 1968. He has five children. The youngest, two years old, was born deformed. Mrs Duc is believed to have drunk or eaten something contaminated by Agent Orange. 'The family own some land which they farm, but they can't do the farming themselves because Mr Duc is disabled and the children are too young to help. 'They have hired some labourers to work on their land. This family, like all the others in the area, eat whatever they grow, and yet they don't have enough food to eat five months of the year. 'Another great problem is water. The closest source of water used to be a river, which is three kilometres away. 'The father had to fetch water for the family from that river every day, making several trips a day as he has only one arm to carry the water. 'Oxfam has helped the villagers to dig two wells in the heart of the village. 'After coming back to Hong Kong, I realised that a tap with running water and a safe road to walk on are two things I take for granted. 'In the places I visited in Vietnam, however, these are the people's biggest needs. 'I would like to return to central Vietnam in a few years' time to see the progress of Oxfam's projects.' Oxfam HK is a relief agency which works with the poor in their struggle against poverty, distress and suffering.
