Overview – Brunei Darussalam lies in Southeast Asia, on the northwest coast of the island shared with Indonesian Borneo and Sabah and Sarawak states of Malaysia. It is bordered on the landward side by Sarawak. The country is composed of two enclaves separated from each other by the valley of the Limbang River in Sarawak. Brunei Darussalam is divided into four districts having an area of 5 770 km² (Table 1).
The districts of Brunei-Muara, Tutong and Belait, which form the larger western portion, are dominated by hilly lowlands, swampy plains and alluvial valleys. Mountainous terrain abounds in the eastern district of Temburong. The highest elevation is Bukit Pagon, at 1 850 m.
The cultivable area is estimated as 13 000 ha, which is about 2.5 percent of the total land area. In 2009, the cultivated area was an estimated 8 000 ha, about 61.5 percent of the cultivable area. About 5 000 ha were under permanent crops, the remaining 3 000 ha being under annual cultivation. In 1997, the cultivated area was estimated as 6 000 ha, of which 4 000 ha was for permanent and 2 000 ha annual crops.
