Agriculture Agriculture in Sungai Liang has seen significant development over the years, with various initiatives contributing to the sector's growth. The 1971 Sungai Liang Agricultural Station report highlighted the positive effects of lime on soil, which led to improved crop yields, including sweet peppers, beans, and brinjals. However, challenges like groundnut rust (
Puccinia arachidis) and waterlogged fields were also noted, though the trials indicated that proper soil conditions could yield better results. According to a 1987 study, of land were being created for fruit tree gardens and homegrown vegetable growing, Sungai Liang possesses potential for agricultural development. Along the beach road, this region is made up of two small land strips. The grey-white
podzolic,
podzol, and
regosol soils have a sandy texture, yet they are enough for agriculture even though they are marginally better than those in certain other areas. The Sungai Liang region also engages in chicken farming in addition to crop agriculture. More recently, AgroZid established a 2.5 hectare chilli farm in Sungai Liang, contributing to the region's agricultural landscape. Marsya Farm, founded in 2000, has been a model of agricultural innovation in the area. Spanning 2.808 hectares in the Agricultural Development Area, the farm grows a variety of crops such as sweet corn, cassava, cherry tomatoes, Taiwanese cucumbers, and leafy vegetables like spinach and mustard greens. Marsya Farm has reached impressive production milestones, including of vegetables in 2020. The farm's produce is sold at the weekly Pasar Kitani and supplied to major supermarkets such as SupaSave and Soon Lee Megamart in Sungai Liang.
Handicrafts The people of Kampung Sungai Liang are also skilled in producing their own goods, such as traditional foods (including confectionery) and handicrafts made from weaving. Notable items include
takiding (woven baskets used for storing ornamental objects) and bamboo squirrels, which have garnered positive attention both locally and internationally. These handwoven products are showcased not only in Brunei Darussalam but also at international expos. Despite being crafted from simple natural materials, the items have received enthusiastic feedback and even orders from local handicraft enthusiasts, highlighting the community's creativity and craftsmanship. The Sungai Liang Authority oversees SPARK, which promotes the growth of an internationally competitive industrial and petrochemical hub. The
Brunei Methanol Company (BMC), SPARK's first major tenant, marking the largest investment outside Brunei's oil, gas, and LNG industries. The plant, capable of producing up to of methanol annually, aligns with
Wawasan Brunei 2035's goals of diversifying the economy and reducing dependence on oil and gas. In addition to the methanol facility, SPARK hosted the
Brunei Fertilizer Industries (BFI), developed by a consortium comprising Westside Limited,
Mitsubishi Corporation, and Australia's
Incitec Pivot. The industrial park also included plans for a demonstration hydrogenation plant, under development by the Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD), a Japanese consortium. Expected to be completed by 2019, the plant aimed to produce 210 tonnes of liquefied hydrogen sourced from the nearby
Brunei LNG plant. The hydrogen was intended for export to Japan, with the first batch planned as fuel for 3,000 cars during the
Tokyo Summer Olympic Games in
2020. With a new factory scheduled for completion in 2027, Polygel Organometallic plans to extend its operations at SPARK. Chemical intermediates including acetic acid and aniline, which are essential for use in rubber, synthetic fibres, plastics, and pharmaceuticals, will be produced at this facility. The 30-acre facility would use feedstock from Brunei's major downstream oil and gas enterprises, Hengyi Industries, BFI, and BMC. It will employ more than seven times as many people as Polygel's current
Salambigar operation. == References ==
