History


Oral traditions

According to Sumbanese historians, Sumba Island was once connected to the neighbouring islands to the north, namely

. Flores and Sumba were connected by the ''Kataka Lindiwatu'' (in Sumba languages), an ancient stone bridge built by the native of Sumba and Flores. Due to the high level of socialization around the ''Kataka Lindiwatu'' which connected both islands, civilization was thought to arise from around those regions (which nowadays correspond to northern Sumba and to part of East Sumba regency territory). This story belongs to the Sumba oral traditions as was written down by Umbu Pura Woha (2007) in his book ().


Ancient civilization ruins

The ruins of the historical civilization of the Sumba people dates back to the BC era; megalithic burials were found on the central regions of the island (Central Sumba) which go back to thousands of years ago. These stone-based burial traditions are still kept alive by the Sumba people and have become a 'living ancient tradition' that still can be observed by scholars in modern days. The megalithic remains found on Sumba Island include dolmen tombs, upright stones, megalithic statues, stone enclosures, and levelled terraces. The Sumba megalithic tradition itself was characterized by the old megaliths built and carved with high quality standards. Some ancient tools are also found on the island. Notable findings are quadrangular

European colonizations

In 1522, the native Sumba came into contact with the Europeans (Portuguese) who arrived on the island by ships to exploit the natural resources of the island. Later, it also attracted the Dutch VOC to come in the region in circa 1600s era. Historically,

Culture

The west part of Sumba is inhabited by segmentary societies made of clans and of politically autonomous villages, while Sumba North and East are occupied by stratified societies (based on
caste A caste is a Essentialism, fixed social group into which an individual is born within a particular system of social stratification: a caste system. Within such a system, individuals are expected to marry exclusively within the same caste (en ...
s) made of clan confederations and led by a dominant clan from which a “king” (''raja'') is chosen, who yields a real political power. Thus West Sumba is more ethnically and linguistically diverse. Both systems exist simultaneously with a 3-tier class system (aristocracy, common people and slaves) assimilated in such a way that - paradoxically - it does not impair the egalitarian functioning of the Western segmentary societies.
Villages almost always include members of several clans, because at each generation many of the youngest ones settle in villages other than the one they originated from - which may belong to an allied clan and not their own original clan and lineage. As of 2021, Sumba is the last place on Earth where societies have remained close to the traditions of South-East Asian hill tribes and still build megalithic monuments such as dolmens for collective burials: more 100 megalithic tombs are still built each year on the island. But this too reflects the East / West difference: the Western segmentary societies built many more dolmens than the Eastern stratified societies; and dolmens in the east are larger, more richly ornated and are reserved to the royal clan. Waingapu, a Kodi village in the west of Sumba, has some 1,400 dolmens - one of the highest concentrations on the island. The Sumbanese have a mixture of Austronesian and

is high.


Water

Access to water is one of the major challenges in Sumba. During the dry season, many streams dry out and villagers depend on wells for scarce supplies of water. 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 was responsible for 48 wells and 191 water stations, 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.
