If you are thinking about travelling to Lesotho, Swaziland, Angola or remote parts in South Africa and Mozambique, it may be worth looking at your itinerary and possibly re-routing. The World Food Programme (WFP) recently warned at a Johannesburg conference that 12.8 million people are on the brink of starvation in southern Africa and urgently need food aid.

Crops have failed across the region due to drought, floods and political breakdown. Hundreds have already died in Malawi but Zambia, Zimbabwe, Angola, Mozambique, Swaziland and Lesotho are also badly hit. The whole Southern African region needs 1.2 million tonnes in emergency aid and about 4 million tonnes to make it through the year, according to the WFP and the UN's food agency.
