(TDLs), where the bulk of high value crops are grown (sugar, forestry, and citrus), are characterised by high levels of investment and irrigation, and high productivity. About 75% of the population is employed in subsistence agriculture upon Swazi Nation Land (SNL). In contrast with the commercial farms, SNL suffers from low productivity and investment. The cultivation of sugarcane, the country's main resource, enslaves part of the population: forced evictions of rural communities to build plantations, child labour, work weeks of up to 60 hours, etc. The International Trade Union Confederation refers to "arduous and unhealthy working conditions, miserable wages and violent repression of any attempt to unionize." Economic growth has lagged behind that of neighbouring countries. Real GDP growth since 2001 has averaged 2.8%, nearly 2 percentage points lower than growth in other Southern African Customs Union (SACU) member countries. Low agricultural productivity in the SNLs, repeated droughts, the devastating effect of HIV/AIDS and an overly large and inefficient government sector are likely contributing factors. Eswatini's public finances deteriorated in the late 1990s following sizeable surpluses a decade earlier. A combination of declining revenues and increased spending led to significant budget deficits. Eswatini's economy is very closely linked to the economy of South Africa, from which it receives over 90% of its imports and to which it sends about 70% of its exports. Eswatini's other key trading partners are the United States (under the African Growth and Opportunity Act) and the EU, from whom the country has received trade preferences for apparel exports to the U.S. and for sugar to the EU. Under these agreements, both apparel and sugar exports did well, with rapid growth and a strong inflow of foreign direct investment. The continued vibrancy of the export sector is threatened by the removal of trade preferences for textiles, the accession to similar preferences for East Asian countries, and the phasing out of preferential prices for sugar to the EU market. Eswatini will thus have to face the challenge of remaining competitive in a changing global environment. The Investment Climate Assessment provides some positive findings, namely that Eswatini firms are among the most productive in Sub-Saharan Africa, although they are less productive than firms in the most productive middle-income countries in other regions. They compare more favourably with firms from lower middle income countries but are hampered by inadequate governance arrangements and infrastructure. Eswatini's currency, the lilangeni, is pegged
