Southern Africa is having one of the worst droughts in years with more than 40 million people expected to face food insecurity because of livestock and crop losses. Botswana, Lesotho, Namibia and Zimbabwe have declared this year's drought an emergency. As Mqondisi Dube reports from Botswana's village of Gamodubu, drought is so frequent that the government plans to stop calling it an emergency and instead make drought a part of the national budget.
