court in the following years. Sarawak's mega-dam policies, such as the Bakun Dam and Murum Dam projects, have submerged thousands of hectares of forest and displaced thousands of indigenous people. Since 2013, the proposed Baram Dam project has been delayed due to ongoing protests from local indigenous tribes. Since 2014, the Sarawak government under chief minister Adenan Satem started to take action against illegal logging in the state and to diversify the economy of the state. Through the course of 2016 over 2 million acres of forest, much of it in orangutan habitats, were declared protected areas. Sources vary as to Sarawak's remaining forest cover: former chief minister Abdul Taib Mahmud declared that it fell from 70% to 48% between 2011 and 2012, the Sarawak Forest Department and the Ministry of Resource Planning and Environment both held that it remained at 80% in 2012, and Wetlands International reported that it fell by 10% between 2005 and 2010, 3.5 times faster than the rest of Asia combined. Economy Historically, Sarawak's economy was stagnant during the rule of previous three white Rajahs. After the formation of Malaysia, Sarawak GDP growth rate has risen due to increase in petroleum output and the rise in global petroleum prices. However, the state economy is less diversified and still heavily dependent upon the export of primary commodities when compared to Malaysia overall. The per capita GDP in Sarawak was lower than the national average from 1970 to 1990. As of 2021, GDP per capita for Sarawak stands at RM 65,971 (US$ 15,173), which is the third highest in Malaysia. However, the urban-rural income gap remained a major problem in Sarawak. Sarawak is abundant in natural resources, and primary industries such as mining, agriculture, and forestry accounted for 32.8% of its economy in 2013. It also specialises in the manufacture of food and beverages, wood-based and rattan products, basic metal products, and petrochemicals, as well as cargo and air services and tourism. The state's gross domestic product (GDP) grew by 40.5% per year on average from 2010 to 2021, but became very more volatile later on, ranging from −3.0% in 2009 to 35.0% in 2021. Sarawak contributed 19.5% of Malaysia's GDP in the nine years leading up to 2020, making it the third largest contributor after Selangor and Kuala Lumpur. From 2015 to 2021, the oil and gas industry accounted for 55.2% of the Sarawak government's revenue.
