中文摘要：在尼日利亚，Aflasafe是一种注册的生物产品，用于减少从田间到仓库的黄曲霉毒素污染，使农产品消费更安全。但重要的问题是农民是否愿意购买和使用这种产品来减少农作物的黄曲霉毒素污染，如果愿意，又是在什么条件下。本文进行了一项研究来解决这些问题，并评估了尼日利亚卡诺和卡杜纳州玉米和花生种植户对该产品支付意愿的决定因素。研究表明，提高黄曲霉毒素安全农产品价格的市场战略、向潜在用户说明Aflasafe的有效性并提高他们的认识，应该会增加Aflasafe的使用。
外文摘要：In Nigeria, Aflasafe is a registered biological product for reducing aflatoxin infestation of crops from the field to storage, making the crops safer for consumption. The important questions are whether farmers will purchase and apply this product to reduce aflatoxin contamination of crops, and if so under what conditions. A study was carried out to address these questions and assess determinants of willingness to pay (WTP) for the product among maize and groundnut farmers in Kano and Kaduna states in Nigeria. A multistage sampling technique was used to collect primary data from 492 farmers. The majority of farmers who had direct experience with Aflasafe (experienced farmers) in Kano (80.7%) and Kaduna (84.3%) had a WTP bid value equal to or greater than the threshold price ($10) at which Aflasafe was to be sold. The mean WTP estimates for Aflasafe for experienced farmers in Kano and Kaduna were statistically the same. However, values of $3.56 and $7.46 were offered in Kano and Kaduna states, respectively, by farmers who had never applied Aflasafe (inexperienced farmers), and the difference here was significant (P< 0.01). Regression results indicate that contact with extension agents (P< 0.01) and access to credit (P< 0.05) positively and significantly influenced the probability that a farmer would be willing to pay more for Aflasafe than the threshold price. Lack of awareness of the importance of Aflasafe was the major reason cited by inexperienced farmers (64% in Kano state and 21% in Kaduna state) for not using the product. A market strategy promoting a premium price for aflatoxin-safe produce and creating awareness and explaining the availability of Aflasafe to potential users should increase Aflasafe usage.
