Introduction
Security in the contemporary world has expanded beyond traditional military threats to include economic, environmental, and human security concerns. This chapter examines various dimensions of security and approaches to achieve it.
1. Traditional Notions of Security
Features:
- Focuses on military threats to territorial integrity
- State-centric approach
- Emphasis on deterrence and defense
- Balance of power as security mechanism
Elements:
- Deterrence: Preventing war by building capacity to retaliate
- Defense: Limiting damage when attack occurs
- Balance of Power: Preventing any one state from dominating
- Alliance Building: Collective security through partnerships
2. Non-Traditional Security
Concept:
- Includes threats beyond military dimensions
- Focus on human security rather than just state security
- Recognizes interdependence of nations
Major Non-Traditional Security Threats:
| Threat | Explanation | Examples |
|---|---|---|
| Poverty | Widespread economic deprivation that undermines social stability and development | Food insecurity, lack of basic amenities, income inequality |
| Migration | Large-scale population movements causing social tensions and resource pressures | Refugee crises, border disputes, human trafficking |
| Terrorism | Violence against civilians for political/ideological goals creating fear and instability | 9/11 attacks, Mumbai 26/11, ISIS activities |
| Epidemics | Health crises that threaten populations and overwhelm systems | COVID-19 pandemic, Ebola outbreaks, HIV/AIDS |
