The amount of pesticides used in crop production in Pakistan has increased rapidly in the last decades, whereas farmers in many areas of the country show little knowledge of safe and efficient use of pesticides. The level of willingness to pay (WTP) for avoiding health risks by pesticides was studied among 318 randomly selected cotton farmers from two districts of the area of Punjab (i.e., Vehari and Lodhran) in Pakistan, using the contingent valuation method. Most farmers felt that pesticide use is a prerequisite for successful cotton production, whereas at the same time they were well aware of pesticide health risks, which they considered minor. The majority of the farmers (77%) showed varying levels of WTP some fee up to 20% of the current pesticide expenditures for avoiding pesticide health risks, but few were willing to pay a fee over 20%. The mean WTP per farmer was low, reaching 5.8 $US on an annual basis. By contrast, a considerable proportion of the farmers (23%) were not willing to pay any fee for avoiding pesticide health risks. These individuals were mostly poor small-scale farmers with limited or no education. High levels of risk perception about pesticides, past experience of pesticide intoxication, high levels of education, and high income were associated with high farmers' WTP for less health risks by pesticides. Farmers who perceived major health risks by pesticides appeared to be highly willing to pay a premium for safe pesticides. Elderly farmers appeared more likely to pay some premium for safe pesticides as a result of higher farming experience and higher income than young farmers. Well-educated farmers were more likely to pay a high premium for safe pesticides. Large farm size was a significant predictor of positive WTP, which was interpreted as an indicator of farmers' wealth.
在过去几十年里,巴基斯坦农作物生产中使用的农药数量迅速增加,而该国许多地区的农民对安全、有效地使用农药几乎一无所知。本研究采用条件价值评估法,在巴基斯坦旁遮普省的两个地区(Vehari 和 Lodhran)随机选择了 318 名棉花种植户,调查了他们对避免农药健康风险的支付意愿。大多数农民认为使用农药是成功种植棉花的前提条件,而与此同时,他们也清楚地意识到农药的健康风险,他们认为这些风险是次要的。大多数农民(77%)表现出不同程度的支付意愿,愿意支付最多 20%的当前农药支出,以避免农药健康风险,但很少有农民愿意支付超过 20%的费用。每个农民的平均支付意愿较低,每年仅为 5.8 美元。相比之下,相当一部分农民(23%)不愿意为避免农药健康风险支付任何费用。这些人大多是贫困的小规模农户,受教育程度有限或没有受过教育。对农药风险的高度认知、农药中毒的过往经历、高教育程度和高收入与农民对减少农药健康风险的高支付意愿有关。那些认为农药存在重大健康风险的农民似乎非常愿意为安全农药支付溢价。由于农业经验丰富和收入较高,老年农民比年轻农民更有可能为安全农药支付一定的溢价。受教育程度高的农民更有可能为安全农药支付高溢价。农场规模大是积极支付意愿的一个重要预测指标,这被解释为农民财富的一个指标。
