非洲近40%的大米是进口的。这大约是世界市场上交易的所有大米的三分之一。如此高度依赖进口。正如2008年粮食危机期间发生的事件所证明的那样，非洲极易受到国际市场冲击的影响，有时会对其粮食安全和政治稳定造成严重后果。在本文中，有人认为，非洲可以把世界市场的上升趋势变成一个历史性的机会，实现其巨大的潜力，稻米生产。在回顾了非洲国家对2008年全球大米危机的政策反应之后，讨论了加强国内大米供应的机遇和挑战。非洲稻米生产的竞争力进行了分析，为选定的国家和水稻生态。增加水稻产量的潜力是使用一个电子表格模拟说明，考虑替代水稻部门的发展设想。缩小产量差距和扩大低地和灌溉水稻种植面积是大幅增加非洲水稻产量的最大潜力。(C)2010爱思唯尔有限公司保留所有权利。
Nearly 40% of the rice consumed in Africa is imported. That is about one third of all rice traded in world markets. With such high dependence on imports. Africa is highly exposed to international market shocks with sometimes grave consequences for its food security and political stability as attested by events during the 2008 food crisis. In this paper, it is argued that Africa can turn the rising trends in world markets to a historical opportunity to realize its large potential for rice production. After a review of the policy responses of African countries to the 2008 global rice crisis, the opportunities and challenges for enhancing domestic rice supply are discussed. The competitiveness of rice production in Africa is analyzed for selected countries and rice ecologies. The potential for increasing paddy production is illustrated using a spreadsheet simulation that considers alternative rice sector development scenarios. Reducing the yield gap and expanding cultivated rice areas under lowland and irrigated hold the greatest potential for substantially increasing paddy production in Africa. (C) 2010 Elsevier Ltd.
