Kratie, northwest Cambodia. In late March, the land in this western corner of the Kingdom is dry and arid. Access to water is limited, coming from wells provided from charitable organisations. The drought, and ensuing sanitation deficiency, is a problem for all the communities living there, including three ethnic minorities: around 570 Khohn; the Mil, numbering 300; and some 1,000 Krol. They differ from their Khmer neighbours in several respects. All speak their own languages and practice Brahmanism, an early religion of the Indian subcontinent that pre-dates Buddhism.
