The food crisis goes far deeper than the latest crop of droughts and floods and rising prices.
Wheat crops are in real danger of being wiped out.
New outbreak of a deadly “Rust” that depletes and destroys wheat crops known as Ug99, so named because it first emerged in Uganda in 1999. At first it was thought to have been controlled within a limited area but it seems to be spreading inexorably. First it hit crops in Kenya, then Ethiopia. Then it jumped across the Red Sea to Yemen and has now been found in Iran. This year it was found in South Africa.
