泰国试验美国开发的大象节育疫苗, 以遏制人类和象的冲突。 Thailand trials U.S.-developed elephant birth control vaccine to curb human-elephant conflicts.

泰国已开始使用美国研制的对特拉特省野生大象的节育疫苗来减少由于扩大农田对森林的侵吞而造成的人类-巨象冲突。 Thailand has begun using a U.S.-developed birth control vaccine on wild elephants in Trat province to reduce human-elephant conflicts caused by expanding farmland encroaching on forests. 该疫苗对家养大象进行成功测试,防止施肥,并提供长达七年的避孕措施。 The vaccine, tested on domesticated elephants with success, prevents fertilization and provides up to seven years of contraception. 2026年1月底,三头野生大象在2026年1月底服用了剂量,剩下的剂量为15剂。 Three wild elephants received doses in late January 2026, with 15 doses remaining. 2025年,30人死亡、29人受伤和2 000多起作物破坏事件成为主要驱动因素。 Officials cite 30 human deaths, 29 injuries, and over 2,000 crop damage incidents in 2025 as key drivers. 该方案针对的是高冲突地区,那里的大象人口年增长率为8.2%,是全国平均水平的两倍以上。 The program targets high-conflict zones where elephant populations grow at 8.2% annually, more than double the national average. 当局正在监测大象接种疫苗的情况,并将这项工作与围栏、生境浓缩和护林员主导的指导结合起来。 Authorities are monitoring vaccinated elephants and combining the effort with fencing, habitat enrichment, and ranger-led guidance.
