Although its territory consists of over 3,000 islands, there is a tremendous concentration of people living on the fertile soil of the two major islands, Java and Bali (population density of 650 people per square kilometre). With a population of about 130 million increasing by about 3 million every year, it is imperative for the Government to find ways of curbing population growth and increasing food production by bringing unfer-tilized land into cultivation. The World Food Programme is giving or has given $60 million worth of food aid to Indonesia in the last seven years to help stimulate development and to feed victims of emergencies. A major part of the development effort has been a UN-supported project to prevent flooding and erosion in the Upper Solo River basin and to promote reforestation and watershed protection measures. WFP food aid is helping to pay the workers' wages. WFP's contribution which started in 1969 is just under $12 million worth of food.
