In Europe, African swine fever virus (ASFV) is one of the most threatening infectious transboundary diseases of domestic pigs and wild boar. In September 2018, ASF was detected in wild boar in the South of Belgium. France, as a bordering country, is extremely concerned about the ASF situation in Belgium, and an active preparedness is ongoing in the country. One of the questions raised by this situation relates to disturbing activities that may affect wild boar movements and their possible impact on the spread of ASFV. Despite evidence of disturbance related to hunting practices, there is a paucity of information on the impact of forestry and human leisure activities. To assess this impact on wild boar movements, a systematic review was first conducted but very few useful data were obtained. For this reason, an expert elicitation was carried out by the French Agency for Food, Environmental and Occupational Health & Safety in order to deal with this knowledge gap. A total of 30 experts originating from France and adjacent neighbouring countries (Spain, Belgium and Switzerland) were elicited about the relative importance of six factors of spatial disturbance of wild boar (noise, smell, invasion of space, modification of the environment, duration and frequency of the activity). Then, for each factor of disturbance, they were asked about the impact of 16 different commercial forestry and human leisure activities. A global weighted score was estimated in order to capture the variability of a wide range of territorial conditions and the uncertainty of expert elicitation. This estimate permitted ranking all 16 activities and aggregating them in three groups according to their potential for disturbance of wild boar, using a regression tree analysis. The results of this expert elicitation provide a methodological approach that may be useful for French and other European decision makers and stakeholders involved in the crisis management of ASF.

评估林业和休闲活动对野猪空间干扰的影响，并潜在地应用于ASF传播风险。

在欧洲，非洲猪瘟病毒（ASFV）是家猪和野猪最具威胁性的跨界传染病之一。2018年9月，在比利时南部的野猪中发现了ASF。法国作为邻国，对比利时的ASF局势极为关切，该国正在进行积极的准备。这种情况引起的问题之一涉及可能影响野猪运动及其对ASFV传播的可能影响的干扰活动。尽管有证据表明与狩猎活动有关的干扰，但是关于林业和人类休闲活动影响的信息很少。为了评估对野猪运动的影响，首先进行了系统的综述，但获得的有用数据很少。为此原因，法国食品，环境与职业健康与安全局进行了专家鉴定，以解决这一知识空白。来自法国和邻近国家（西班牙，比利时和瑞士）的总共30位专家被引出关于野猪空间干扰的六个因素（噪声，气味，空间入侵，环境变化，持续时间和持续时间）的相对重要性。活动的频率）。然后，针对每个干扰因素，询问他们16种不同的商业林业和人类休闲活动的影响。对全球加权得分进行了估计，以捕获各种领土条件的变化和专家引诱的不确定性。通过使用回归树分析，该估算值可以对所有16种活动进行排名，并根据它们对野猪造成干扰的可能性将其分为三类。这一专家启发的结果提供了一种方法学方法，可能对法国和其他欧洲决策者以及参与ASF危机管理的利益相关者有用。
