Agriculture is one of the key sectors within the Indonesian economy. In the last 50 years, the sector's share in national gross domestic product has decreased considerably, due to the rise of industrialisation and service sector. Nevertheless, for the majority of Indonesian households, farming and plantation remains as a vital income generator. In 2013, the agricultural sector contributed 14.43% to national GDP, a slight decline from 2003's contribution which was 15.19%. In 2012, the agricultural sector provides jobs to approximately 49 million Indonesians, representing 41% of the country's total labor force.
