Economics of African Animal Trypanosomosis (AAT) management strategies under risk and time preferences

非洲牛的动物锥虫病和对杀锥虫药物的广泛耐药性的威胁一直是疾病控制和预防的主要投入，对西非棉花带小农作物畜牧生产系统中资源贫乏的养牛户来说是重要的生产风险。该区域最近的研究突出表明，迫切需要提高对抗药性发展的认识，并找到可持续遏制和预防抗药性的方法。本研究的总体目标是分析尽管存在AAT和耐药性，但仍能实现畜牧业生产可持续性的选择。在这种情况下，农民的决策行为与两个因素，即时间偏好和对风险的态度起着重要的作用。这是影响农民疾病预防控制投入选择的两个主要变量。基于这些参数的同时启发，通过在马里和布基纳法索的农民的代表性样本之间的经济田间试验，这些信息适用于生物经济模型，适合比较疾病控制策略。

African animal trypanosomosis (AAT) in cattle and the threat of widespread resistance to trypanocidal drugs, that has been the major input of disease control and prevention, are important production risks to resource-poor cattle farmers in smallholder crop livestock production systems in the cotton belt of West Africa. Recent studies in that region underline the urgency to improve the understanding of drug resistance development and to find ways of its sustainable containment and prevention. The overall goal of this research is to analyze options that can lead to the sustainability of livestock production in spite of AAT and drug resistance. In this context the decision making behaviour of farmers with regard to two factors, namely time preference and attitude towards risk plays an important role. These are two major variables affecting farmers’ input choice of disease control and prevention. Based on the simultaneous elicitation of these parameters by means of economic field experiments among a representative sample of farmers in Mali and Burkina Faso these information are applied to a bio-economic model suitable to compare disease control strategies.
