The influence of risk preferences, knowledge, land consolidation, and landscape diversification on pesticide use
通过实验、调查和遥感数据，比较了风险偏好、知识、土地整合和景观多样化四类因素对农民农药使用量的相对重要性，发现景观多样化影响最大，而损失和模糊偏好比风险偏好更关键。
Abstract Researchers have spent substantial effort to identify factors influencing pesticide use intensity. However, few studies have compared the relative importance of these factors. This study examines four categories of factors that potentially influence farmers’ pesticide use decisions by evaluating incentivized experiment data, farm survey data, and remote sensing data in China. Our results suggest that land diversification has the largest effect on farmers’ pesticide use. Compared with the most rice‐intensive landscape type, less rice‐intensive systems cause farmers to spray less on middle rice. Heavy pesticide use intensity is associated with land fragmentation as small‐scale farms still dominate crop production. Farmers’ integrated pest management knowledge has significant effects on pesticide use. We also find that loss and ambiguity preferences, rather than risk preferences, are more likely to affect pesticide use intensity.
