Outside the Catholic mission I walked through rows of women in traditional hide skirts, squatting or sitting with legs astride, palms upturned in supplication. Many suffered from scabies and cradled emaciated babies, and all looked 20 years older than their true age. These are my memories of the Uganda famine in 1980 and these were the survivors. Africa is a different place today and so are the methods used to combat famine. But this was where I learnt about the contradictions of overseas aid. Aid is pernicious, and injudicious aid can destroy all before it. Take food aid. It is wonderful for saving those in extreme peril, but once the extreme event has passed, it destroys farmers and local markets, and inevitably leads to corruption.
