Abstract

ABSTRACT Smallholder farmers’ decisions to adopt improved varieties are expected to be critically governed by their preferences and willingness to pay for different traits of these varieties. This study examined farmers’ preferences for sorghum (Sorghum bicolor (L.) Moench) variety attributes and estimated their willingness to pay (WTP) for these attributes using choice experiment data from >1,300 sorghum farmers in Tanzania. Empirical findings showed that farmers had strong preferences for sorghum varieties that were tolerant to environmental stresses, high yielding, early maturing, fetching higher grain prices, and white in color. Significant heterogeneity was observed in farmers’ preferences across various traits. The WTP estimates revealed that farmers were willing to pay the highest premium for tolerance to environmental stresses, amounting, on average, to three times higher than the WTP for other traits. Our results have important implications for demand-driven variety development that could contribute to improving crop productivity and household welfare.

农民对高粱品种特性的偏好和支付意愿：为坦桑尼亚的产品开发和育种计划提供信息

摘要：小农户采用改良品种的决定预计将严格取决于他们对这些品种不同特性的偏好和支付意愿。本研究调查了农民对高粱品种属性的偏好，并使用坦桑尼亚1300多名高粱农民的选择实验数据估计了他们为这些属性支付的意愿。实证结果表明，农民对耐环境胁迫、高产、早熟、粮价高、色泽白的高粱品种有强烈的偏好。农民对各种性状的偏好存在显著的异质性。WTP估计显示，农民愿意为承受环境压力支付最高的溢价，平均而言，这比其他性状的WTP高出三倍。我们的研究结果对需求驱动的品种开发具有重要意义，有助于提高作物生产力和家庭福利。
