Logging road in East Kalimantan: logged forest on the left, primary forest on the right

Illegal logging has removed much of the original forests of the province. Less than half the original forest remains in places such as the Kayan Mentarang the Kutai national parks.

The projects that supports tropical rainforest conservation includes a WWF project[8] and Samboja Lestari lodge, one of Borneo Orangutan Survival Foundation's reforestation and orangutan rehabilitation projects.[9]


East Kalimantan's economy heavily depends on earth resources such as oilfield exploration, natural gas, coal and gold.[citation needed] Balikpapan has an oil refinery plant that was built by Dutch governance before World War II, destroyed during World War II, and rebuilt after Indonesian independence.[citation needed]

Other developing economic sectors include agriculture and tourism.[citation needed]

Obstacles to economic development include a lack of transportation infrastructure.[citation needed] Transportation depends on traditional boats connecting coastal cities and areas along main river, Mahakam River.[citation needed]

In 2012, Russia's state railway firm Joint Stock Company (JSC) signed a Memorandum of Understanding with the East Kalimantan Governor over railway lines to transport coal and other freight. The first stage will connect an area near Balikpapan port to West Kutai Regency in a 183-kilometer line and is estimated to cost about $1.8 billion. It will commence in 2013 and by 2017 it is hoped that it carry 20 million tons of coal annually. The second phase will connect a line to Murung Raya in Central Kalimantan with a 60 kilometer line, which will cost an estimated $600 million.[10]

Several oil fields have been discovered in the Mahakam River Delta including Attaka, Badak (1971), Semberah, Nilam, Sanga Sanga, Bekapai (1972), Handil (1974), Samboja, Jakin and Sepinggan.[11][12][13] The Handil, Badak and Bekapai fields are anticline structural traps with oil reservoir sandstones between 450 and 2900 m.[11]:399 The delta is in the Kutei basin, bounded by the Mankalihat and Paternoster carbonate arch, containing Eocene shales overlain by Oligocene fluvial deposits during marine regression, culminating in the formation of the delta in the late Miocene.[11]:400

Tourist sites

In addition to Derawan Islands, East Kalimantan has a unique natural site, Labuan Cermin Lake at Biduk-biduk district which features fresh water on top with about 2 meters thickness and sea water underneath it. Both fresh water fish and sea water fish live in the lake inhabiting their respective habitat layer. "Cermin" means mirror in Indonesian language and the lake was named so due to the clarity of the water.[14]

North Kalimantan Province

North Kalimantan was formally inaugurated as the 34th province of Indonesia on April 15, 2013. The new province was previously part of East Kalimantan Province and Irianto Lambrie will be acting as the governor of it until a new governor is chosen by their people in an election.[15]
