Madagascar has received just $1 million from its $242 million appeal to help cope with natural disasters this year, the United Nations has said.
Madagascar made the appeal last month, saying cyclone damage and rising flood waters have covered houses, cut off main roads and destroyed an estimated 200,000 tonnes of rice on the world's fourth-largest island.
In the south, drought has affected 582,000 people, including 7,000 children under the age of five with acute malnutrition, the UN children's agency Unicef said.
"After over forty days of extensive relief operations in locations around the country, the nation's response services are overstretched at best," Unicef said.
Floods this cyclone season have killed seven people and displaced more than 32,000, most in the capital Antananarivo.
Experts estimate that flooding might cause the loss of 10 per cent of this year's agricultural production.
