Malawi is one of the world's least developed countries and is ranked 170 out of 187 countries according to the 2010 Human Development Index. It has about 16 million people, 53% of whom live under the national poverty line, and 90% of whom live on less than $2 per day. The United Nations Children's Fund (UNICEF) estimated that there are 46,000 severely malnourished children. Today, many programs are put in place in Malawi to address climate instability, poverty and diversification in term of both the economy and agriculture.
