Poor 2009 crop prospects in the Horn of Africa following below-average rains, combined with conflict and displacement are aggravating an already serious food insecurity situation in the region, according to the United Nations Food and Agriculture Organization (FAO), dpa reported. Nearly 20 million people currently depend on food assistance in the region, and this number may increase as the "hunger season" progresses, particularly among subsistence farmers, pastoralists and low-income urban dwellers, the Rome-based FAO said in a statement Monday. The effects of the oscillaton in ocean temperature known as El Nino, which usually brings heavy rains towards the end of the year, could make matters worse, resulting in floods and mudslides, destroying crops both in the field and in stores, increasing livestock losses and damaging infrastructure and housing, FAO warned. Across Eastern Africa prices of maize, a major staple, have shown a declining trend since the beginning of the year, but remain higher than they were two years ago, FAO noted. In Uganda and Kenya, prices of maize in June 2009 were almost double their level 24 months earlier. In Khartoum, Sudan, June 2009 prices of sorghum, another staple crop, were more than double their levels in June 2007. Similarly, prices in Mogadishu, Somalia, still remain higher than the pre-crisis period, despite declining since mid-2008. For pastoralists, lack of adequate pasture has worsened livestock conditions and reduced market prospects, impacting their incomes and ability to access staple foods. In Uganda, production of 2009 first season crops, completed in early August, is forecast at well below average levels, representing the fourth successive poor harvest. In the country's northern Acholi region, first season cereal and pulse production is estimated about 50 per cent below the average. In Kenya, the poor performance of the 2009 "long rains" maize crop, combined with already depleted national cereal stocks, exports bans in neighbouring countries and persistent high cereal prices, has reduced food access. The maize crop, which accounts for 80 per cent of total annual production, is estimated at 1.84 million tons, about 28 per cent below normal levels. In Ethiopia, production of the secondary "belg" season crop is also estimated at levels well below average. Scarce rains have resulted in crop losses of up to 75 per cent in some of the hardest hit areas. With the partial failure of the "belg" season crop, the number of people in need of emergency assistance is expected to increase by 1.3 million to 6.2 million, FAO said. According to FAO's Food Security and Nutrition Analysis Unit, Somalia is facing the worst humanitarian crisis in 18 years, with approximately half the population - an estimated 3.6 million people - in need of emergency livelihood and life-saving assistance. This includes 1.4 million rural people affected by the severe drought, about 655,000 urban poor facing high food and non-food prices, and 1.3 million internally displaced people, a result of escalating fighting and conflict, FAO said.
