AIDS Hitting African Farm Sector Hard Once a largely urban problem, AIDS has moved to rural areas in developing countries, devastating thousands of farming communities and leaving impoverished survivors scarcely able to feed themselves. The disease is no longer a health problem alone, but is having a measurable impact on food production, household food security and rural people" s ability to make a living. The latest statistical evidence on sub-Saharan Africa—the worsthit region—confirms the scale of the epidemic" s impact on the countryside. It is estimated that over half of the 28 million people living with HIV/AIDS in sub-Saharan Africa live in rural areas. In order to estimate such figures, epidemiologists start with data taken from tests done on blood samples from pregnant women attending prenatal clinics. They then extrapolate the figures to estimate infection rates in larger areas. Recent findings point to two of the hardest-hit countries— Zimbabwe and Swaziland. "This is a real wake-up call for governments," says an expert on AIDS "Policy-makers are guided by evidence. Solid evidence is now coming in and will make governments understand how rural areas are actually more vulnerable to AIDS than urban areas. Recent reports from other African countries show a similar pattern of rampant rural infection. Poverty underlies the suffering and devastation behind these figures. The HIV/AIDS epidemic cannot be addressed without doing something about rural livelihoods: how people make their living, how they get enough food, what strategies they follow in order to survive.

The Shape of Things to Come When the world was a simpler place, the rich were fat, the poor were thin, and right-thinking people worried about how to feed the hungry. Now, in much of the world, the rich are thin, the poor are fat, and right-thinking people are worrying about obesity. Evolution is mostly to blame. It has designed mankind to cope with deprivation, not plenty. People are perfectly tuned to store energy in good years to see them through lean ones. But when bad times never come, they are stuck with that energy stored around their expanding bellies. Thanks to rising agricultural productivity, lean years are rarer all over the globe. Modern-day Malthusians, who used to draw graphs proving that the world was shortly going to run out of food, have gone rather quiet lately. According to the UN, the number of people short of food fell from 920m in 1980 to 799m 20 years later, even though the world" s population increased by 1. 6 billion over the period. This is mostly a cause for celebration. Mankind has won what was, for most of his time on this planet, his biggest battle: to ensure that he and his offspring had had enough to eat. But every silver lining has a cloud, and the consequence of prosperity is a new plague that brings with it a host of interesting policy dilemmas. As a scourge of the modern world, obesity has an image problem. It is easier to associate with Father Christmas than with the four horses of the apocalypse. But it has a good claim to lumber along beside them, for it is the world" s biggest public-health issue today—the main cause of heart disease and diabetes. Since the World Health Organization labeled obesity an "epidemic" in 2000, reports on its fearful consequences have come thick and fast.
