In Sarawak, the main problems are the excessive exploitation of the forests , and the building of or projects for huge dams . In Kalimantan, forestry is adding to the problems raised by Transmigration , the government policy aiming at settling these areas. The concomitants of this policy are active resettlement and regroupment in villages. There are also swamp forests.
Population density is highest along the coast and decreases as one goes inland.
There are a few exceptions, but generally speaking, the indigenous populations of Borneo live along the main navigable rivers. The main towns and commercial centres are on the coast.
