Reuters journalist Peter Apps (C) is attended to at the scene of a car accident outside Batticaloa in this September 5, 2006 file photo. In a developed country, proper care, equipment and money can make life relatively long and productive, even for someone with such severe disabilities. Yet in the developing world, even surviving such an injury is practically unheard of. Living with it long-term, with all the expense of permanent care, is all but impossible.

Children await treatment in a hospital in the central Angolan city of Huambo September 12, 2005. The United Nations says half of Angola's children are malnourished and in some areas more than 50 percent have been permently stunted due to lack of food. Food and agricultural production is recovering from the effects of a 27 year civil war but aid workers say lack of good roads or railways means there is little incentive for subsistence farmers to shift into cash crops they will be unable to get to market.

HIV positive Ziphi Mzila collects water outside her home near Msinga in the country's rural Kwa-Zulu Natal province on April 13, 2005. Mzila was diagnosed HIV positive in 2000 after AIDS-related illnesses forced her to quit growing and selling tomatoes, the main way which she fed her three children. AIDS will kill 20 percent of southern Africa's agricultural workers by 2020, researchers said on Thursday, possibly threatening food production in a region already facing frequent shortages.

In the village of Likupa, the vegetables have come up but the more vulnerable maize harvest - the staple for much of the mountain kingdom of Lesotho's 2.2 million people - has failed for lack of rain.
