Mozambique has 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 serious setbacks in 2000 and 2001 when Mozambique was hit by floods that affected about a quarter of the population and destroyed much of national infrastructure. Furthermore, in 2002, a severe drought hit many central and southern parts of the country, including previously flood-stricken areas. Poverty remains widespread, with more than 50% of Mozambicans living on less than $1 a day (BBC). Maternal and child health remain major concerns for the country.
