Dutch East Indies

, although the island did not come under real
Dutch administration until the 20th century. The Dutch mission started in 1886. One of the missionary was Douwe Wielenga. Jesuits opened a mission in
Laura, West Sumba.
Historically, this island exported
sandalwood and was known as ''Sandalwood Island'', or ''Sandel Island''.
Despite contact with western cultures, Sumba is one of the few places in the world where
megalithic burials are used as a 'living tradition' to inter prominent individuals when they die. Burial in megaliths is a practice that was used in many parts of the world during the
Neolithic and
Bronze Ages. It has survived to this day in Sumba and has raised significant interest from scholars.

August 19, 1977, an earthquake measuring 7.0 on the

Geography, climate and ecology

The largest town on the island is the main port of
Waingapu, with a population of 35,932 in 2021.
The landscape is low, limestone hills, rather than the steep volcanoes of many Indonesian islands. There is a dry season from May to November and a rainy season from December to April. The western side of the island is more fertile and more heavily populated than the east.
Due to its distinctive flora and fauna Sumba has been categorised by the
World Wildlife Fund as the Sumba deciduous forests
ecoregion. Although generally thought to be originally part of the

Fauna

There are a number of mammals, but the island is particularly rich in bird-life with nearly 200 birds, of which seven
endemic species and a number of others are found only here and on some nearby islands. The endemic birds include four vulnerable species — the secretive

The
Sumba hornbill or ''Julang Sumba'' (''Rhyticeros everetti'') is under increasing threat of extinction. Indiscriminate deforestation is threatening their survival. The population is estimated at less than 4,000 with an average density of six individuals per square kilometre. A hornbill can fly to and from over an area of up to 100 square kilometres.
Threats and preservation
Most of the original forest has been cleared for the planting of
maize,
cassava, and other crops so only small isolated patches remain. Furthermore, this clearance is ongoing due to the growing population of the island and this represents a threat to the birds.
In 1998 two national parks were designated on the island for the protection of endangered species: the

Water
Access to water is one of the major challenges in Sumba. During the dry season, many streams dry up and villagers depend on wells for scarce supplies of water. Many villagers have to travel several kilometres several times a day to fetch water. It is mainly the women and children who are sent for water, while the men are at work. The
Sumba Foundation has been active in raising sponsorship to drill wells in villages and attempting to reduce poverty on the island. As of February 2013, the
Sumba Foundation were responsible for 48 wells and 191 water stations, a supplying 15 schools with water and sanitation, and reducing malaria rates by some 85%.
Electricity
Electricity mainly comes from diesel generators. New projects include 3 MW Bayu wind power plant (PLTB) in Kadumbul, East Sumba by PT Hywind. Another is the Bodo Hula Biomass Power Plant (PLTBm), West Sumba. 1 MW capacity. Other existing renewable electricity projects involve solar PV and micro-hydroelectricity.
