As the former royal capital of Laos, Luang Prabang has long been a leading Buddhist centre, home to numerous temples and monasteries. Tourism has increased massively, in part due to the city's inclusion on Unesco's World Heritage List in 1995, and now this way of life is under threat.

Every day before sunrise, monks leave the temples in silent procession to ask for donations from Buddhist devotees.

The tourists outnumber the faithful. Photograph: Truls BrekkeIn side streets, the mood is more pious. Local residents wait outside their houses with donations of rice or vegetables, ready to distribute them peacefully among the passing monks.
