SWAZILAND SYSTEM

major division of rocks and time in southern Africa in Precambrian Time (3.96 billion to 540 million years ago). The system consists of a great thickness of sedimentary and metamorphic (altered) rocks with numerous intrusions of igneous bodies. Two major subdivisions of the Swaziland System are recognized, an Upper and a Lower series. Many of the units that constitute the Swaziland System contain mineral deposits of great value, including gold, copper, and uraniuma circumstance that has spurred intensive study and exploitation. The economy Overall, the economy displays a marked duality of large-scale intensive production and small-scale semi-subsistence activities. This produces a great contrast in incomes and living standards, which tends to be obscured by average per capita statistics. National economic policy is based on the free enterprise or market philosophy, with fiscal measures to redistribute resources to education, health, and community improvement projects. Government revenue is derived principally from receipts from the Southern African Customs Union, sales tax, and corporate and personal taxation. The budget is generally in balance, but foreign aid is a major contributor to the capital or development budget, providing a buffer to help meet any deficit in revenue. Nevertheless, the dual economy persists, and the formal employment sector is unable to absorb the annual increment of new workers generated by the country's high population growth rate. Many workers, mostly men, are forced to seek employment as migrant workers, predominantly in South Africa. Labour relations in the country are at an embryonic stage, with a generally fragmented trade union movement pitted against a longer-established employers' association and with the government endeavouring to act as referee and arbiter. Agriculture and forestry About two-thirds of the population lives in the rural areas, where a mixture of subsistence and commercial farming is practiced. The staple crop is corn, and other crops include sorghum (mainly for the brewing of traditional beer), pumpkins, beans, peas, and other vegetables. Crop yields are generally low, but the more progressive farmers produce on a par with the large-scale commercial sector. Because of the role of cattle as a traditional store of wealth, the livestock population, mostly cattle and goats, greatly exceeds the country's carrying capacity and is a major cause of vegetation loss and soil erosion. Large-scale commercial farming is held mainly in the hands of foreigners, although since independence the Swazi nation has acquired a large stake in this sector, especially in the largest agro-industry, the cultivation of sugarcane and the manufacture of sugar. Also of major commercial importance are the extensive man-made forests of pine and eucalyptus (in the Highveld), which supply timber to a wood-pulp mill and several sawmills. Unbleached wood pulp is the country's second largest export after sugar. The area under timber plantations is about 6 percent of the country's total area. Other important crops are citrus fruits and cotton (Lowveld), pineapples (Middleveld), rice, tobacco, and vegetables. Commercial livestock farming is also important, particularly in the Lowveld, and supports meat processing and dairy plants. The land Relief and soils A long and complex geologic history has created a landscape with a surprising variety of relief, climate, and soils for such a small country. There are four well-defined physiographic regions, extending longitudinally from north to south in roughly parallel belts. From west to east they are the Highveld, the Middleveld, the Lowveld, and the Lubombo (Lebombo) escarpment. Geologically, the oldest formations are in the west, and the youngest are in the east. The Highveld, covering about 30 percent of the country, is a complex of granites and more ancient metamorphosed quartzites, sandstones, and volcanics that has been eroded into a rugged mountain land. The average elevation is between 3,500 and 4,500 feet (1,100 and 1,400 metres); the highest points are the summit massifs of Bulembu (6,108 feet [1,862 metres]) and Ngwenya (5,997 feet [1,828 metres]) in the extreme west. Known to the Swazi as Inkangala (a cold, treeless place), the Highveld was the last part of the country to be settled. Its deeper-weathered red to yellow acid soils have developed on the gentler gradients and in river valleys. The Middleveld occupies about one-fourth of the country and has an average altitude of 2,000 to 2,500 feet. It is a region of rolling uplands and wide, well-watered valleys. It is mainly underlain by ancient granites and gneisses (metamorphosed granites), with dolerites and quartzites, which have weathered deeply to produce friable red and clay loams interspersed with shallower profiles of sands and sandy loams. To the Swazi it is known as Live (The Country) or Inkabave (The Navel) and is the heartland of the Swazi nation. The Lowveld, or Bushveld, covering nearly 40 percent of the country, is a generally undulating lowland with isolated knolls and ridges rising abruptly above the general level of 500 to 1,000 feet. In general, the soils reflect the transition from the acidic granites and sandstones of the western Lowveld to the more basic basalts and dolerites of the eastern parti.e., from sandy loams in the west to red and black clays in the east, the latter being some of the most naturally fertile soils in the country. This region is called Lihlanze by the Swazi, meaning a warm place with treesin its undisturbed state, the typical African savanna. The Lubombo escarpment and plateau covers about 5 percent of the country, consisting of a narrow strip of about 600 square miles. It rises abruptly from the Lowveld to an average altitude of 2,000 feet, with higher peaks (Siteki and Mananga) of about 2,500 feet in the north. It is deeply dissected by the gorges of three of the main rivers that traverse the country from west to east, the Umbuluzi, the Usutu, and the Ingwavuma. The plateau soils vary considerably, from shallow sands to deeper loams, depending on the composition of the volcanic lavas that form the bedrock. The Swazi have no specific name for this part of the country. Drainage Swaziland is one of the best-watered countries in southern Africa. Major perennial rivers, which have their sources in South Africa, flow through the country to the Indian Ocean. They are the Lomati, the Komati, the Umbuluzi, and the Usutu. The Usutu has the largest catchment in the country, with three main tributaries, the Usushwana, the Ngwempisi, and the Mkhondvo. In the south the Ingwavuma rises in western Swaziland and also cuts through the Lubombo. The people The Swazi nation is an amalgamation of more than 70 clans. Their chiefs form the traditional hierarchy under the ngwenyama and ndlovukazi, who are of the largest clan, the Dlamini. The amalgamation brought together clans already living in the area that is now Swaziland, many of whom were of Sotho origin, and clans of Nguni origin who entered the country with the Dlamini in the early 19th century. Traditional administration and culture are regulated by an uncodified Swazi Law and Custom, which is recognized both constitutionally and judicially. The language is siSwati, which is akin to Zulu, though it shares official status with English, which is in fact used generally for official written communication. The Swazis comprise about 97 percent of the population, the remainder being immigrants from Mozambique, South Africa, and the rest of the world. Included among these are a few thousand Europeans and Asians and their families engaged in business activities. The majority of Swazis belong to Christian churches, both Roman Catholic and Protestant, whose missions were responsible before independence for much of the education and health services, particularly in the rural areas. However, many adherents also retain the traditional beliefs and practices of the rest of the population.
