本研究利用一系列不同的数据集和分析方法，结合农民的定性评估和来自面板数据生产函数分析和化肥支付意愿估计的定量证据，探讨了农业生产力的制约因素和提高马达加斯加主要主食水稻生产力的优先事项。在全国范围内，农民主要寻求提高劳动生产率的干预措施，例如，改善获得农业设备、牲畜和灌溉的机会。据报告，减轻冲击的措施、提高土地生产力的技术和改善土地保有权的重要性要小得多。贫穷农民的稻米产量明显低于富裕农民，土地也明显较少。最贫穷人口在采取减缓气候冲击措施和使用化肥方面的估计生产力收益最大。然而，水稻上使用化肥似乎利润微薄，而且多年来变化很大。旨在降低化肥供应链中的成本和价格波动的研究和干预措施可能至少有助于更容易进入的地区更容易采用化肥。
This study explores the constraints on agricultural productivity and priorities in boosting productivity in rice, the main staple in Madagascar, using a range of different data sets and analytical methods, integrating qualitative assessments by farmers and quantitative evidence from panel data production function analysis and willingness-to-pay estimates for chemical fertilizer. Nationwide, farmers seek primarily labor productivity enhancing interventions, e.g., improved access to agricultural equipment, cattle and irrigation. Shock mitigation measures, land productivity increasing technologies and improved land tenure are reported to be much less important. Poorer farmers have significantly lower rice yields than richer farmers, as well as significantly less land. Estimated productivity gains are greatest for the poorest with respect to adoption of climatic shock mitigation measures and chemical fertilizer. However, fertilizer use on rice appears only marginally profitable and highly variable across years. Research and interventions aimed at reducing costs and price volatility within the fertilizer supply chain might help at least the more accessible regions to more readily adopt chemical fertilizer.
