With water supply from the Kelalan river, the community have created well-irrigated padi fields in Buduk Bui and Long Langai, and grow the prized, small-grained “Highland Adan Rice” with fine, sweet grains. This is unusual in the mountainous interior of Sarawak, where most communities can only grow upland rice known as "hill padi". Planting takes place each year in August and September, and harvesting starts in January. Delicacies related to rice such as "bee pang" (rice crackers) and "bera kopi" (rice coffee, produced by frying rice with sprinkling of sugar) are also produced by Lun Bawang people.
