2-Minute Revision
Disaster Mitigation and Preparedness are the twin pillars of modern, proactive disaster management. Mitigation focuses on long-term strategies to reduce the severity or likelihood of a disaster's impact, encompassing both structural measures like resilient infrastructure (e.
g., earthquake-resistant buildings, flood embankments) and non-structural measures such as land-use planning, stringent building codes, and environmental protection. Its aim is to build inherent resilience.
Preparedness, conversely, involves immediate actions to ensure effective response when a disaster strikes. This includes developing comprehensive emergency plans, establishing robust Early Warning Systems (EWS) with their four critical components (risk knowledge, monitoring, dissemination, response capability), conducting regular mock drills, stockpiling essential supplies, and fostering community awareness.
India's Disaster Management Act, 2005, provides the legal framework, establishing the NDMA, SDMAs, and DDMAs to formulate and implement these strategies. The National Disaster Management Plan aligns with the global Sendai Framework for DRR, emphasizing a holistic approach that integrates climate change adaptation and community participation to build a truly disaster-resilient nation.
5-Minute Revision
Disaster Mitigation and Preparedness are fundamental to a proactive disaster management cycle, moving beyond traditional reactive relief efforts. Mitigation involves long-term, sustained efforts to reduce the potential impact or occurrence of hazards.
This is achieved through structural measures, which are physical interventions like constructing dams, embankments, cyclone shelters, or retrofitting buildings for seismic resistance. Equally vital are non-structural measures, which include policy, legal, and educational initiatives such as land-use zoning, enforcing strict building codes (e.
g., BIS codes), public awareness campaigns, and promoting disaster insurance. The goal is to reduce vulnerability and exposure systematically.
Preparedness focuses on readying communities and institutions for an effective response when a disaster is imminent or strikes. Key elements include developing comprehensive emergency plans at national, state, and district levels, establishing and maintaining robust Early Warning Systems (EWS).
A strong EWS comprises four pillars: understanding the risk, monitoring the hazard, disseminating timely and actionable warnings, and ensuring a community's capacity to respond. Technologies like satellite imagery, Doppler radars, and SMS alerts are crucial here.
Other preparedness activities involve capacity building through training (e.g., NDRF, SDRF, 'Aapda Mitra' volunteers), conducting regular mock drills to test plans, and stockpiling essential relief supplies.
India's legal backbone for this is the Disaster Management Act, 2005, which established a multi-tiered institutional framework: the NDMA (National, chaired by PM), SDMAs (State, chaired by CM), and DDMAs (District, chaired by DM/Collector).
These bodies are responsible for formulating policies, plans, and guidelines. India's National Disaster Management Plan (NDMP) aligns with the global Sendai Framework for Disaster Risk Reduction (2015-2030), which outlines four priority areas: understanding risk, strengthening governance, investing in DRR, and enhancing preparedness for 'Build Back Better'.
Challenges remain in effective implementation, particularly concerning funding, inter-agency coordination, enforcement of building codes, and ensuring 'last-mile' connectivity for warnings. The integration of climate change adaptation and leveraging digital technologies are emerging priorities to enhance India's overall resilience.
