Savu or Sabu Island
 
Savu (also known as Sawu, Sabu, Sawoe, Havu, Hawu, Hawoe) is an island which is situated midway between Sumba and Rote, west of Timor, in Indonesia's eastern province, East Nusa Tenggara. Ferries connect the islands to Waingapu, on Sumba, and Kupang, in West Timor. It is also possible to fly to Savu from Kupang.

Geography
The Savu Islands (Kepulauan Savu) include Rai Hawu, Rai Jua and Rai Dana. The three islands are fringed by coral reef and sandy beaches. Rai Dana is a small, uninhabited island, situated thirty kilometres south-west of Rai Jua. From April to October, deep ocean swells pound the south facing coastlines.

The land is covered for the most part by grassland and palms. The climate is dry for large parts of the year, due to hot winds blowing from the Australian continent. Most rain falls during the months from November to March. Between 82% & 94% of all rain falls during the west monsoon, with little or no rain falling for the months of August to October. The mean annual rainfall for Savu Island is 1019 mm. During the dry season, the islands' streams dry up, so the islanders depend on wells for their water supply.

Vulcanism
The Savu Islands are situated in a tectonic subduction zone, where the Indo-Australian Plate is moving northward, sliding under the Eurasian Plate. The islands lie on a ridge that was created by volcanic eruptions caused by the plate movement. Sediments carried into the Earth's crust heat up and rise in plumes of magma, which cool and solidify to form igneous rock. The Sumba Ridge is no longer volcanically active, however there are active volcanoes on the island of Flores, to the north.

The compression of the two tectonic plates is causing the Savu Islands to rise at a rate of about 1 mm per year. Occasionally, however, the tectonic plate suddenly slips a much greater distance, resulting in an earthquake. In 1977, a major earthquake, registering 7.9 on the Richter Scale, struck 280 km W/SW of Rai Jua. This triggered an enormous tsunami, which swept across the coastal plain at Seba, reaching as high as the airport. No one was reported missing on Savu or Rai Jua. However, on the neighbouring islands of Sumba and Sumbawa, the death toll reached 180.

Society

The population is about 30 000. Savu has strong historical ties with Hinduism in Java and the people consider themselves of Hindu origin. The society still performs traditional animistic beliefs, known as Djingi Tiu. Dutch missionaries introduced Protestantism which remains on the islands today.

Agriculture
Savunese culture is ecologically fitting for such an arid environment. The traditional clan agreements on land control and water distribution ensure that the land is carefully managed and not over exploited. Their gardens form a well structured ecology, emulating a tropical forest with diverse species of trees and shade plants.

Agricultural production on Savu includes corn, rice, roots, beans, livestock (meat/milk) and seaweed, which was introduced by Japanese interests, in the early 1990s. Pigs, goats and chickens are commonplace in the villages. Those farmers who depend on mixed crop gardens or on mung bean fields are generally better able to manage during times of poor rain but are seemingly less successful when the rains are good.

Corn, as a single crop, remains the predominant staple on Savu, though most farmers try to plant several different fields to increase their chances of at least one successful harvest. Cotton is the main crop on Rai Jua, where the standard of living is below that of Savu. It is used to make traditional textiles.

Corn is planted in late November, December or early January and harvested from February through to March; rice and also mung beans are planted later, usually in January, after soils are well saturated with rain. In El Ni�o years, farmers are frequently misled by initial rains, which offer promise but then cease. Most farmers keep some seed reserves if they are forced to plant a second time during the wet season.

Rarely do farmers have sufficient seed reserves for a third attempt at planting and by the time such a third planting seems necessary, there is little likelihood of success. By mid-March the rains begin to diminish and it is no longer possible to plant corn with any expectation of a good harvest.

Prior to the corn harvest, the poorer segments of the population survive on reserve foods, primarily cassava, some sweet potato, forest yams and sugar supplies from tapping lontar palms. This period is known as the time of "ordinary hunger". However, during periods of drought, when the planting and subsequent harvest of the corn crop is delayed, the period of ordinary hunger is extended and "ordinary hunger" becomes "extraordinary hunger". Most families manage on one meager meal a day.

Livestock, suffering from the same conditions as the human population, are consumed or sold to buy emergency foods. People turn to green papaya, eaten as a vegetable, and tamarind seeds. In the dry season, drinking water becomes difficult to obtain and is often polluted by animals seeking water. Women and younger girls spend more time than ever carrying water for their families. A strong indicator of the "extraordinary hunger" period is a sharp increase in gastro-intestinal diseases. Children are particularly vulnerable.

Contact with European

Initial contact was with the Dutch Vereenigde Oost-Indische Companie in 1648. References to Savu from the period invariably concern Savunese soldiers, mercenaries or slaves. In 1674, the crew of a Dutch sloop were massacred in East Savu, after their vessel ran aground.

The Dutch responded by forming an alliance with the raja of Seba, so troops could be sent in to retaliate. However, they failed to enter the fortress of Hurati, in B'olou Village of Eastern Savu, as it was ringed by three defensive walls. To save face, the Dutch force accepted payment in the form of slaves, gold and beads.

In 1770, Captain James Cook visited Savu, staying three days before continuing on to Batavia. It was the first European voyage to have scientists on board. During the three year expedition, botanists Joseph Banks and Daniel Solander collected over three thousand five hundred plant species along with specimens of animals, minerals and ethnographic materials that on their return fascinated Europeans.

Cook's visit to Savu was brief and, though he and Joseph Banks produced detailed records of the island and its people, their accounts were based for the most part on information provided by Mr Lange, the German representative of the Dutch East India Company, who was stationed on Savu at the time.
