Jharkhand, known for its rich natural resources and tribal culture, is also vulnerable to a range of natural hazards due to its geographical and climatic conditions. Effective disaster management is critical for mitigating the impacts of these hazards and ensuring the safety and well-being of its residents. This article explores the natural hazards prevalent in Jharkhand and the measures taken for disaster management.
Natural Hazards in Jharkhand
Droughts
Causes:
Uneven and erratic rainfall.
Dependency on monsoon for agriculture.
Impacts:
Crop failure leading to food insecurity.
Migration of rural populations to urban areas.
Affected Areas:
Palamu, Garhwa, Chatra, and Latehar districts are highly prone to droughts.
Floods
Causes:
Heavy monsoon rains.
Poor drainage systems in urban areas.
Overflowing of rivers like the Subarnarekha, Damodar, and Koel.
Impacts:
Loss of life and property.
Spread of waterborne diseases.
Affected Areas:
Areas near the Damodar Valley are particularly flood-prone.
Heatwaves
Causes:
Rising global temperatures and local deforestation.
Prolonged dry spells during summer.
Impacts:
Increased cases of heatstroke and dehydration.
Reduced productivity, particularly in labor-intensive sectors.
Affected Areas:
Ranchi, Jamshedpur, and other urban centers.
Earthquakes
Causes:
Jharkhand lies in Seismic Zone II and III, which are low to moderate-risk zones.
Impacts:
Damage to poorly constructed buildings.
Risk to mining areas due to structural instability.
Affected Areas:
Areas around mining zones like Dhanbad and Bokaro.
Forest Fires
Causes:
Hot and dry summers.
Human activities like slash-and-burn agriculture.
Impacts:
Loss of biodiversity.
Increased carbon emissions.
Affected Areas:
Saranda and Palamu forests are highly susceptible.
Landslides
Causes:
Mining activities disrupting soil stability.
Heavy rainfall in hilly areas.
Impacts:
Damage to infrastructure and transportation.
Displacement of local communities.
Affected Areas:
Eastern plateau regions and mining zones.
Disaster Management in Jharkhand
Institutional Framework
State Disaster Management Authority (SDMA)
Formulates disaster management policies and strategies.
Coordinates with the central government and other stakeholders.
District Disaster Management Authorities (DDMAs)
Implements disaster management plans at the district level.
Oversees relief and rehabilitation activities.
Jharkhand State Disaster Management Plan
A comprehensive document detailing hazard mapping, risk assessment, and mitigation strategies.
Mitigation Measures
Drought Mitigation
Promotion of water conservation techniques such as rainwater harvesting.
Construction of check dams and ponds.
Encouragement of drought-resistant crops.
Flood Control
Development of embankments and flood control reservoirs.
Strengthening of drainage systems in urban areas.
Real-time monitoring of river water levels.
Heatwave Management
Creation of public awareness campaigns about preventive measures.
Establishment of cooling shelters in urban areas.
Distribution of drinking water in heatwave-prone regions.
Earthquake Preparedness
Enforcement of building codes to ensure earthquake-resistant structures.
Regular mock drills in schools and public institutions.
Installation of seismographs for monitoring seismic activity.
Forest Fire Prevention
Deployment of firewatch teams during the dry season.
Awareness campaigns for local communities on fire hazards.
Use of satellite technology to detect forest fires early.
Landslide Risk Reduction
Regulation of mining activities to prevent soil erosion.
Afforestation in vulnerable areas to stabilize soil.
Construction of retaining walls in hilly regions.
Emergency Response Mechanisms
Early Warning Systems
Use of meteorological data to predict weather-related hazards.
SMS-based alerts for local communities.
Relief and Rescue Operations
Deployment of National Disaster Response Force (NDRF) teams.
Coordination with NGOs and civil society for relief distribution.
Post-Disaster Rehabilitation
Compensation for loss of life and property.
Reconstruction of damaged infrastructure.
Livelihood support for affected populations.
Community Involvement
Capacity Building
Training programs for local communities in disaster preparedness.
Formation of village-level disaster management committees.
Awareness Campaigns
Use of media to educate people about disaster risks and safety measures.
School-based programs to inculcate a culture of safety.
Volunteering
Encouragement of youth participation in disaster response activities.
Creation of local volunteer networks.
Challenges in Disaster Management
Lack of Resources
Inadequate funding for disaster management projects.
Shortage of trained personnel and modern equipment.
Coordination Gaps
Poor communication between state, district, and local authorities.
Lack of integration between government agencies and NGOs.
Technological Limitations
Insufficient use of advanced technologies like GIS for hazard mapping.
Limited real-time monitoring capabilities.
Environmental Degradation
Deforestation and mining exacerbate natural hazards.
Unsustainable agricultural practices increase vulnerability.
Way Forward
Strengthening Governance
Establishment of a dedicated disaster management fund.
Regular audits of disaster preparedness at all levels.
Leveraging Technology
Use of drones for damage assessment and rescue operations.
Development of mobile apps for real-time hazard information.
Public-Private Partnerships
Collaboration with private entities for funding and expertise.
Corporate Social Responsibility (CSR) initiatives for disaster mitigation.
Sustainable Development
Adoption of eco-friendly mining and industrial practices.
Promotion of renewable energy to mitigate climate change impacts.
