Elephant ranges in Asia overlap with human-use areas, leading to frequent and often negative two-way interactions, a fraction of which result in human fatalities. Minimizing such negative interactions rests on gaining a mechanistic understanding of their patterns and underlying processes. In Chhattisgarh (India), a rewilding population of 250–300 elephants that have recently expanded their range from neighbouring states through dispersal has been causing annual losses of >60 human lives. Using logistic regression models, we examined the influences of eight plausible predictors of the occurrence of elephant-related human fatality incidents. We found that 70% of incidents occurred in areas with high-intensity habitat use by elephants; the other 30% were in areas of intermediate and sporadic elephant habitat use. The probability of human fatalities was high along the roads connecting settlements and in areas with frequent house break-ins by elephants, and this probability was also affected by the spatial geometry of forest patches. Immediate practical options to minimize fatal interactions include community-based early-warning systems and the use of portable barriers around settlements. Judicious landscape-level land-use planning aimed at maintaining the resilience of remnant intact elephant habitats will be critical to preventing the dispersal of elephants into suboptimal habitats, which can create complex conflict situations.

大象被动野化的影响:印度人类死亡人数评估

亚洲的大象活动范围与人类活动区域重叠,导致频繁且往往是负面的双向互动,其中一部分导致人类死亡。最大限度地减少这种负面相互作用取决于对它们的模式和潜在过程的机械理解。在恰蒂斯加尔邦(印度),250-300头大象重新野生化,最近通过扩散从邻国扩大了活动范围,每年造成超过60人死亡。使用逻辑回归模型,我们研究了与大象相关的人类死亡事件发生的八个合理预测因素的影响。我们发现 70% 的事件发生在大象高强度栖息地的地区;其余 30% 位于大象栖息地中度和零星利用的地区。在连接定居点的道路沿线和大象经常闯入房屋的地区,人类死亡的概率很高,而且这种概率也受到森林斑块空间几何形状的影响。最大限度地减少致命相互作用的直接实用选择包括基于社区的预警系统和在定居点周围使用便携式屏障。旨在维持剩余完整大象栖息地恢复能力的明智的景观级土地利用规划对于防止大象分散到次优栖息地至关重要,这可能会造成复杂的冲突局势。最大限度地减少致命相互作用的直接实用选择包括基于社区的预警系统和在定居点周围使用便携式屏障。旨在维持剩余完整大象栖息地恢复能力的明智的景观级土地利用规划对于防止大象分散到次优栖息地至关重要,这可能会造成复杂的冲突局势。最大限度地减少致命相互作用的直接实用选择包括基于社区的预警系统和在定居点周围使用便携式屏障。旨在维持剩余完整大象栖息地恢复能力的明智的景观级土地利用规划对于防止大象分散到次优栖息地至关重要,这可能会造成复杂的冲突局势。
