Subsistence agriculture still accounts for half of the GDP and provides 80% of employment. Only 4.01% of the country is arable land, and a mere 0.34% used as permanent crop land, the lowest percentage in the Greater Mekong Subregion. Rice dominates agriculture, with about 80% of the arable land area used for growing rice. Approximately 77% of Lao farm households are self-sufficient in rice.
