This article reports on trends in organized violence, building on new data by the Uppsala Conflict Data Program (UCDP). The falling trend in fatalities stemming from organized violence in the world, observed between 2014 and 2019, was decisively reversed in 2021 as fatalities increased significantly. UCDP registered more than 119,100 deaths in organized violence in 2021, a 46% increase from the previous year. The increase was largely driven by escalating conflicts in Afghanistan, Ethiopia, and Yemen. Fatalities increased in all three categories of organized violence, despite a decrease in the number of active state-based conflicts, as well as the number of actors carrying out one-sided violence against civilians. UCDP recorded 54 state-based conflicts in 2021, a decrease by two compared to the previous year. Five of the conflicts were active at the intensity of war, the lowest number of wars since 2010. Violence in 2021 was thus concentrated to fewer but bloodier conflicts. Unmanned aerial vehicles (UAVs), commonly known as drones, have become increasingly important features of modern conflicts, and the trend in their usage is discussed in the special feature section. UAV usage has since 2019 dispersed among a significant larger number of actors, even as the downscaling in the involvement of the United States in the war on terror has led to a decrease in drone-related fatalities.

本文以乌普萨拉冲突数据计划 (UCDP) 的新数据为基础，报告有组织暴力的趋势。2014 年至 2019 年期间观察到的世界有组织暴力造成的死亡人数下降趋势在 2021 年得到彻底扭转，因为死亡人数显着增加。2021 年，UCDP 记录有超过 119,100 人死于有组织的暴力事件，比上一年增加了 46%。这一增长主要是由阿富汗、埃塞俄比亚和也门不断升级的冲突推动的。尽管活跃的以国家为基础的冲突数量以及对平民实施片面暴力的行为者数量有所减少，但所有三类有组织暴力的死亡人数均有所增加。UCDP 在 2021 年记录了 54 次基于州的冲突，与上一年相比减少了两次。其中五场冲突在战争激烈的情况下活跃，这是自 2010 年以来战争数量最少的一次。因此，2021 年的暴力集中在数量较少但更加血腥的冲突上。无人驾驶飞行器 (UAV)，俗称无人机，已成为现代冲突日益重要的特征，其使用趋势将在专题部分讨论。自 2019 年以来，无人机的使用分散在大量参与者中，尽管美国参与反恐战争的规模缩小导致与无人机相关的死亡人数减少。以及它们的使用趋势在专题部分讨论。自 2019 年以来，无人机的使用分散在大量参与者中，尽管美国参与反恐战争的规模缩小导致与无人机相关的死亡人数减少。以及它们的使用趋势在专题部分讨论。自 2019 年以来，无人机的使用分散在大量参与者中，尽管美国参与反恐战争的规模缩小导致与无人机相关的死亡人数减少。
