Mozambique emerged as one of the world's fastest-growing economies with foreign investors showing interest in the country’s untapped oil and gas reserves in spite of its very low level of human development. Most of the population works the land and infrastructure nationwide still suffers from the effects of colonial neglect, war, and underinvestment. The economy suffered severe setbacks in 2000 and 2001 when Mozambique was hit by floods that affected about a quarter of the population and destroyed much of the nation's infrastructure. Furthermore, in 2002, a severe drought hit many central and southern parts of the country, including previously flood-stricken areas. Deprivation remains common, with 50% of Mozambicans living in poverty (2008). Maternal and child health remain major concerns for the country. National economic expansion, while notable, has not been as effective at reducing poverty when compared to other countries in the region.
