Primary Sector

Although Sidoarjo territory is relatively small and densely populated, but primary sector is still maintain a role in Sidoarjo economy. Agriculture is mainly produced in western and south-western part of Sidoarjo mainly Tulangan District, Krembung District, and Balongbendo District. During colonial era, Sidoarjo was famous for sugarcane production and it was hosted several sugar mills owned by Colonial government. After Independence, Indonesia government nationalised all of sugar mills in Sidoarjo. Sugarcane production sector peaked in 70s and gradually declining since then, due to inflows of manufacturing investment and rapid urbanization that reduced sugarcane planting area. Today, agricultural crops that still produced in Sidoarjo are Rice, Banana, Papaya, Cassava, and several lowland vegetables.

Fisheries also still maintain a role. In the past, Sidoarjo is known as a fishing town but fishing sector are slowly declining as Sidoarjo became more urbanized. Today, fishing is replaced by aquaculture as a main source of fish in Sidoarjo.

Sidoarjo is also famous for its processed fisheries products, such as prawn cracker, fish cracker, shrimp paste and petis.

Education Services is also predicted to grow, as several private tutoring companies are opening their branch in Sidoarjo and private school are gaining more students, due to increasingly population, income, and lack of capacity in state school.

Lapindo Mud flow[edit]

Since May 2006, more than 10,000 people in the Porong District have been displaced by the hot mud flowing from a natural gas well being drilled by Lapindo Brantas, an oil well company that is part of a conglomerate owned by Coordinating Minister for the People's Welfare Aburizal Bakrie.[7] Gas and hot mud started spewing from the well on May 28, when the drill penetrated a layer of liquid sediment. Attempts to pump concrete down the well did not stop the flow. While some scientists have speculated that the earthquake that struck Yogyakarta on May 27, the day before the well erupted, may have cracked the ground, creating potential pathways for the mud to reach the surface, others have suggested that the drilling procedure was faulty by not using a casing. This is likely to be incorrect as technical papers on the subject showed that there were up to four sets of casing installed and cemented in the well. Some 50,000 cubic metres of hot mud were erupting every day as of August; in September, the amount increased to some 125,000 cubic metres daily.[8] On September 26 barriers built to hold back the mud failed, resulting in the flooding of more villages. Gus Maksum, one of the thousands of Sidoarjo villagers displaced by the mud flow gives a detailed first-hand account of the first year of the disaster in his memoir Titanic Made By Lapindo.[9] As of late September 2006 scientists are saying that the eruption may be a mud volcano forming, and may be impossible to stop.[10][11][12]
