本文利用农业气候有利地区 Chokwe 灌溉计划的数据，研究了莫桑比克低地水稻绿色革命的潜力和制约因素。我们的数据显示，尽管潜力很大，但灌溉水供应不足、化肥价格过高以及劳动力成本适中阻碍了该计划实现这一潜力。首先，改善灌溉至关重要，因为它不仅直接提高产量，而且通过与化肥的互补关系间接提高产量。我们还发现，改善信贷准入非常重要，因为它可以通过市场获取这些昂贵的投入品，从而增加化肥和劳动力的使用。旺季无法雇佣和交换劳动力是劳动力集约利用的另一个制约因素。引入成熟期较短的水稻品种可以放宽插秧时间，从而分散旺季的劳动力需求。
This paper investigates the potential of and constraints to a lowland rice Green Revolution in Mozambique, using data from an agro-climatically favorable area, the Chokwe irrigation scheme. Our data show that, although the potential is high, the insufficient supply of irrigation water, excessively expensive chemical fertilizer, and moderately costly labor hinder the scheme from achieving that potential. First of all, an improvement in irrigation is crucial as it increases yield not only directly but also indirectly through its complementary relationship to chemical fertilizer. We also find that an improvement in credit access is important as it can increase the application of chemical fertilizer and labor by making the acquisition of these expensive inputs through markets possible. The unavailability of hired and exchange labor during peak seasons is another constraint to the intensive use of labor. The introduction of rice varieties with a shorter maturity duration would relax the timing of transplanting and thus spread out the peak seasons’ labor demand.
