摘要

尽管非洲对大米的人均需求增加，但所有大陆的大米消费增长要么放缓，要么呈负增长。未来对大米的额外需求将主要来自非洲和亚洲的人口增长。过去产量增长带动的产量增长有助于满足全球水稻需求。然而，非洲在实现预期产量方面仍然远远落后于其他大陆。需要在各大洲进行更多的研究，以生产具有更高产量潜力和所需粮食质量的品种，并更多地侧重于非洲大陆。到2050年，全球对大米的需求将减少约5.84亿吨。随着水稻研究领域的积极技术发展，到2050年，水稻农业的形态将发生变化。到2050年，亚洲可能损失约500万公顷，非洲可能增加约1000万公顷的水稻地。

The global rice agriculture towards 2050: An inter-continental perspective

The growth in rice consumption has either slowed down or become negative in all the continents although additional per capita demand for rice exists in Africa. The future additional rice demand will mainly come from the population growth in Africa and Asia. The production growth during the past led by growth in yield has helped in meeting rice demand around the globe. However, Africa continues to lag far behind other continents in achieving the desired level of yield. Additional research efforts are needed in all continents for the production of varieties with higher yield potential and desired grain quality with more emphasis on the African continent. The global demand for rice will be about 584 million tons or less towards 2050. With positive technological developments in the rice research arena, the shape of rice agriculture will change towards 2050. Asia may lose about 5 million ha and Africa gain about 10 million ha of rice land by 2050.
