大米在尼日利亚的重要性不再是问题，而是我们如何满足日益增长的需求、减少进口并实现自给自足的问题。人均消费量从2.9公斤(1970/74)跃升至24.1公斤(1995/99)。我们的产量在此期间增加了6倍，达到327万吨，但到1998年，我们的进口量为100万吨，占西非进口总量的三分之一。到1999年，水稻收获面积为220万公顷，其中65%来自旱地。然而，我们的平均产量是1.5吨/公顷。已有55个不同生态类型的高产品种正式发布，另有6个旱地NERICA品种正在酝酿中。管理好的低地优良品种，亩产可达6吨以上。但由于糟糕的治水系统和糟糕的土壤管理，这些潜力在农民的田野上从未实现。这就是为什么需要再次呼吁为更好的水土管理做法作出协调一致的努力，在本文中称为*Sawah系统和更好的政策。
The importance of rice in Nigeria is no longer the question but rather how can we meet the growing demand, reduce import and be self-sufficient. Consumption per capita jumped from 2.9 kg (1970/74) to 24.1 kg (1995/99). Our production figure increased by 6 times within the period to 3.27 million tons but our importation figure by 1998 stood at 1 million tons accounting for one third of the total import for West Africa. By 1999 area harvested from rice stood at 2.2 million hectares of which 65% was from rainfed lowland. However our yield average is 1.5 t/ha. There are 55 high yielding varieties for various ecologies officially released and another 6 NERICA varieties in the pipeline for upland areas. The lowland elite varieties with good management could yield up to 6 tons per ha. But these potentials are never achieved on farmers’ field because of poor water control system and bad soil management. This is why a renewed call for a concerted effort needs to be made for a better water and soil management practices referred to in this paper as *Sawah System and better policies.
