Counterterrorism Yearbook 2021

By Leanne Close and Daria Impiombato

ASPI is delighted to release its 5th edition of the Counterterrorism (CT) yearbook, edited by Leanne Close, APM and Daria Impiombato. The 2021 yearbook provides a comprehensive picture of the current global terrorism landscape. The yearbook's 29 authors found Covid-19—a key theme in most chapters—to have had an impact on global terrorism. However, pervasive online social media platforms have played a more significant role, increasing terrorists’ ability to radicalise and incite individuals to commit terrorist acts, as well as encouraging financial support to terrorist groups.

The yearbook begins with an overview of current trends and the terrorism landscape in 2020 identified in the 8th Global Terrorism Index (GTI) produced by Australia’s Institute for Economics and Peace.

As well as analysis of the impacts of Covid-19 on terrorist threats globally, several key themes emerge from the yearbook’s chapters, consistent with the trends identified in the GTI. These include the impact of social media and technology on terrorist events and radicalisation, and a nexus between terrorism and organised crime. One concerning example highlights the impact of natural disasters on violent extremism, with a study of 167 countries over 30 years from 1970, which found that an increase in deaths from natural disasters resulted in an increase in terrorism-related deaths and attacks in the following two years.

Strong examples of prevention and strategies to counter violent extremism are outlined in the yearbook, providing governments and CT practitioners with contemporary analysis of current and emerging challenges and offering key policy recommendations to combat radicalisation, violent extremism and terrorism in all its forms.
