Between the 1970s and 1990s, Cambodia was ravaged by civil war. Since its return to peace there has been a boom in tourism with over two million visitors every year.
Keen to help this war-torn country, increasing numbers of tourists are now also working as volunteers. Most come with the very best of intentions - to work in schools and orphanages, filling a gap left by a lack of development funding.
But, inadvertently, well-intentioned volunteers have helped to create a surge in the number of residential care homes as impoverished parents are tempted into giving up their children in response to promises of a Western-style upbringing and education. Despite a period of prosperity in the country, the number of children in orphanages has more than doubled in the past decade, and over 70 per cent of the estimated 10,000 'orphans' have at least one living parent.
