The U.N. agency is holding its 28th Regional Conference on Africa this week in Tunis. The FAO gave the bleak description of Africa despite some strong economic growth in recent yearsan average 4.8 percent increase in Gross Domestic Product, or GDP, between 2000 and 2010. It says the problem stems from low agricultural productivity, low incomes in rural areas and high rates of malnutrition. There have been improvements, though. The FAO cites greater production of staple crops, the growing of better varieties of bananas in eastern and central Africa and the planting of higher yielding maize. Theres also greater production of cotton, teas and flowers. But the agency says its not enough to ensure food security for a growing population amid climate change. FAO Assistant Director-General Bukar Tijani said the conference is focusing on greater investment in smallholder farmers. Women play the major role in such farms, but Tijani says there will now be an emphasis on attracting youth. |
