Geography and Environment of Indonesia

The Republic of Indonesia encompasses the world’s longest archipelago. From the tiny island of Sabang in the northwest to Papua (formerly Irian Jaya or West Irian) in the east, over 17,000 islands stretch some 3,400 miles along the Equator. The total land area covers about 736,000 square miles. The main islands, in terms of population and importance, are Java, Sumatra, Bali, Kalimantan (Borneo), Sulawesi (Celebes), Papua, and the Maluku. The landscape is highly varied with mountain peaks and volcanoes, some rising to over 15,000 feet. In central Papua, snow covers some peaks all year.
