Sumbawa

Sumbawa lies in the Wallacea biogeographical region, between the Asian and Australian continental shelves, resulting in a unique mix of flora and fauna. The island is dominated by volcanic mountains, including Mount Tambora, which rises to 2,850 meters and is the site of the largest volcanic eruption in recorded history in 1815. The climate is markedly drier than western Indonesia, with a pronounced dry season from April to November, which shapes the island's savanna-like vegetation and agricultural practices. Rivers are mostly seasonal, and water scarcity is a recurring challenge for both farming and domestic use. The island's coastline features coral reefs and deep-water harbors, supporting fishing and small-scale maritime trade.

Sumbawa's history is marked by the rise of two major sultanates: the Sultanate of Sumbawa (in the west) and the Sultanate of Bima (in the east), which emerged in the 17th century under the influence of Makassar and later Dutch colonial power. These sultanates left a legacy of Islamic culture blended with indigenous animist traditions, visible in ceremonies, textiles, and the use of the Sumbawa and Bima languages. The island was a peripheral but active participant in the spice trade, exporting sandalwood, horses, and rice. The 1815 eruption of Tambora destroyed the local kingdoms and caused a global 'year without a summer,' but the island recovered and later became part of the Dutch East Indies. Today, the majority of Sumbawa's population is Muslim, and traditional villages maintain distinct social hierarchies and customary law (adat).

The economy of Sumbawa is primarily agrarian, with rice, corn, and cassava as staple crops, alongside livestock raising, particularly horses and cattle, which are exported to other islands. Fishing and seaweed farming are significant along the coast, while small-scale gold and copper mining operate in the west, notably at the Batu Hijau mine, one of Indonesia's largest copper-gold mines. Tourism is growing but remains limited compared to Bali or Lombok, with attractions such as the Tambora caldera, traditional villages, and surfing spots. Environmental concerns include deforestation, soil erosion, and the impact of mining on water quality. Conservation efforts focus on protecting the island's endemic species, such as the Sumbawa horse and the critically endangered Sumbawa tiger (now extinct), and on sustainable management of marine resources.

Beyond its well-known features, Sumbawa harbors several obscure but notable facts. The island is home to the Sumbawa horse, a small, hardy breed used for transport and racing, and the Sumbawa deer, a subspecies of the Javan rusa. The 1815 Tambora eruption buried the former kingdom of Tambora, and archaeological excavations have uncovered a Pompeii-like site with artifacts and human remains. The island's traditional song and dance, such as the 'Mpaa Lengo' dance, are rarely performed outside the region. Sumbawa also has a unique script, known as 'Satera Jontal,' used for writing on palm leaves, which is now endangered. In the 20th century, the island was a site of internal conflict during the Indonesian National Revolution, and later became a destination for transmigrants from Java and Bali, altering its demographic and cultural landscape.
