Part 1 – Linkages Between Development and Spread of Extremism

Development and internal security are closely interconnected. Regions experiencing persistent poverty, unemployment, poor governance, inadequate infrastructure and social exclusion are more vulnerable to extremist ideologies. Although lack of development alone does not cause extremism, it can create conditions that extremist organizations exploit for recruitment and expansion. Therefore, sustainable development and good governance are essential components of India's internal security strategy.

The Government of India follows a comprehensive approach by combining security operations with socio-economic development, infrastructure creation, education, healthcare, skill development and employment generation to address the root causes of extremism.
