Dominica

Relief, drainage, and soils

The island is of volcanic formation. Dominica has a number of active volcanoes, although eruptions are rare. Other signs of geothermal activity include fumaroles (volcanic vents) and hot springs. In the south, Boiling Lake lies 2,300 feet (700 metres) above sea level; its waters are often forced 3 feet (1 metre) above normal by the pressure of escaping gases. The island has rich alluvial and volcanic soils. There are numerous rivers, all of them unnavigable. A range of high forest-clad mountains runs north to south, broken in the centre by a plain drained by the Layou River, which flows to the west; the highest points are Mount Diablotins (4,747 feet [1,447 metres]) and Mount Trois Pitons (4,670 feet [1,424 metres]).

Climate

Dominica has a pleasant climate, particularly during the cooler months from December to March. Summer temperatures reach an average high of 90 °F (32 °C). Winter temperatures are not much lower, the average high being anywhere from 84 to 86 °F (29 to 30 °C). The dry season is from February to May, and the rainy season is from June to October, the most likely period for hurricanes (tropical cyclones). Rainfall varies, being especially heavy in the mountainous interior. Average annual coastal rainfall varies from about 60 inches (1,500 mm) to 145 inches (3,700 mm), but in the mountains average rainfall can reach 250 inches (6,350 mm).

Plant and animal life

Dominica is the most heavily forested island of the Lesser Antilles. The forest is the habitat of a considerable variety of birds and animals. Two parrots—the imperial parrot, or sisserou (Amazona imperialis), and the smaller red-necked parrot (Amazona arausiaca)—are found only in Dominica. There are many hummingbirds, of which the blue-headed (Cyanophaia bicolor) is native only to Dominica and the neighbouring island of Martinique. The large frog known as crapaud or mountain chicken (Leptodactylus fallax), one of four amphibian species on the island, was long an emblematic part of Dominica’s fauna (and a national dish), but it has become highly endangered because of a fungal disease.

Agriculture, forestry, and fishing

Agriculture remains the most important sector of the economy, in terms of both employment and contribution to the gross national product. The main crops are bananas, citrus fruits, and coconuts. Bananas accounted for nearly half of Dominica’s export earnings in the 1980s, but in the late 20th and early 21st centuries the banana crops were devastated repeatedly by hurricanes. Production also fell in the 1990s in part as a result of a World Trade Organization ruling that the European Union had breached free-trade rules by offering Dominica and other former European colonies—notably, other eastern Caribbean banana-producing islands—preferential access to the European market. Cocoa, coffee, and vegetables are also produced. Dominica is self-sufficient in fruit and vegetables and exports foodstuffs to Guadeloupe. The forests have potential for marketable timber. The fishing industry was devastated by Hurricane David in 1979, when nearly all of the island’s fishing boats were destroyed, but, beginning in the 1990s, a new fishing port and market were built at Roseau (and subsequently repaired and renovated) with Japanese financial support.

Resources

Pumice, a volcanic rock used chiefly for building purposes, is the most important commercial mineral. There are also deposits of clay and limestone. Extensive copper deposits in the northeast have been investigated for possible exploitation.

Manufacturing, trade, and services

Most of the main products and exports are derived from the agricultural sector; they include copra, coconut oil, soap, bay oil, and fruit juices. Soap, derived from coconut oil, is an important export. There is a small garment-assembly sector. Wood products, including furniture, are produced from local timber. Portsmouth is the main boatbuilding centre. Imports include food, mineral fuels, and manufactured goods.

Tourism developed dramatically in the late 20th century despite the island’s poor transportation infrastructure and the relative lack of hotel facilities and good beaches. Approximately 80,000 “stay-over” tourists visit the island each year, while the ports of Prince Rupert Bay and Roseau serve more than 300,000 cruise-ship passengers on day visits annually. The island has sought to develop reserves of its unique flora and fauna to attract tourists and markets itself as the “nature island” of the Caribbean.
