Blandongdiensten was linked with which colonial need?

Correct answer: Felling and supplying timber for shipbuilding

Blandongdiensten was a Dutch colonial system in Java under which people of forest villages had to provide labour for cutting and transporting timber. The timber was important for colonial requirements, especially shipbuilding. Salt production, indigo cultivation and coffee plantations were colonial activities, but they were not the central purpose of Blandongdiensten. Exam tip: remember Blandongdiensten as a forced timber-labour system for the Dutch.
