Of these, 1,3 million have been displaced since the beginning of the year.
Floods have worsened the displacement crisis after leaving 137 000 people without homes.
Following the disaster, the number of internally displaced people has doubled since the beginning of the year. Instability has also worsened malnutrition.
Humanitarian partners are now seeking around $330 million (R4,8 billion) to assist about 3 million of the most vulnerable people this year.
This is an increase of $67 million (R985 million) compared to the appeal launched at the beginning of the year.
The upward review of the budget aims to mobilise substantial resources to meet urgent and growing needs.
The United Nations Office for the Coordination of Humanitarian Affairs said the increase was justified by the rise in the number of vulnerable people and the urgent need of interventions in the sectors of food security, nutrition, protection and shelter and non-food items.
Mali, the West African country of 18 million people, is also contending with an uprising by rebel Islamist groups.
