DRRR 2 Flashcards
Is actions taken to reduce the risk of disasters and the adverse impacts of natural hazards, through systematic efforts to analyze and manage the causes of disasters, including through avoidance of hazards, reduced social and economic vulnerability to hazards, and improved preparedness for adverse events” - UN International Strategy for Disaster Reduction (ISDR)
The conceptual framework of elements considered with the possibilities to minimize vulnerabilities and disaster risks throughout a society, to avoid (prevention) or to limit (mitigation and preparedness) the adverse impacts of hazards, within the broad context of sustainable development.
- United Nations Office for Disaster Risk Reduction
Disaster Risk Reduction
- Ensure that DRR is a national and local priority with strong institutional basis for implementation.
- Identify, assess, and monitor disaster risks - and enhance early warning. 3. Use knowledge, innovation, and education to build a culture of safety and resilience at all levels.
- Reduce the underlying risk factors.
- Strengthen disaster preparedness for effective at all levels.
- (Hyoga Framework of Action, adopted in UNWCDR, Hyoga, Japan in 2005)
Steps for Implementing DRR Strategy
Components of Disaster Risk Reduction: (4)
- Mitigation
- Measures to be taken before and after an event
- Preparedness
- Measures to be taken before and after an event
- Response
-Measures to be taken during and immediately after an event
- Recovery
- Post disaster measures
is the effort to reduce loss of life and property by lessening the impact of disasters. It is permanent reduction of the risk of a disaster. lessens the likelihood and severity of disaster by implementing sustained actions, such as improved construction practice, to reduce or eliminate long-term risk to people and property. Mitigation of hazard impacts reduces the possibility of disaster and reduces the need for assistance.
includes recognizing that disasters will occur; attempts are made to reduce the harmful effects of a disaster, and to limit their impact on human suffering and economic assets.
Mitigation
Types of Mitigation
- Primary Mitigation:
Primary mitigation refers to increasing the resistance to the hazard and reducing vulnerability.
- Secondary Mitigation:
Secondary mitigation refers to reducing the effects of the hazard (preparedness).
Various Approaches/Strategies of Disaster Mitigation: (7)
1) Risk Identification
The first step in disaster mitigation is to identify areas that are at risk to hazard. Once the priority zones have been identified, comprehensive and integrated risk reduction programs should be initiated.
2) Land-Use Planning
Land-use planning includes the mapping of disaster prone area which should contain
number of livestock per unit area, crop density, population density, road network, location of
shelter etc.
3) Structural and Non-Structural
Mitigation measures may involve construction (e.g. dykes and flood protection walls, and also ecosystem-based approaches to flood and erosion control, such as planting mangrove forests) and non-material measures (e.g. land-use restrictions in flood risk areas).
4) Disaster relief and Rehabilitation
Supply emergency humanitarian aid to victims for survival and relocate the peoples whose residence have been destroyed very badly, inappropriate for living.
5) Disaster Management Training and Education
Trained up group of personnel need to be formed in local, national and regional context to mitigate and reduce disaster risk and damages. 6) Role of Media in Disaster Risk Reduction
Media is the effective means to circulate the news and bulletins about hazard warning and
mitigation processes.
7) Institutional Capacity Building
Several institutional bodies are engaged with disaster mitigation processes such as local community, organization, local and national government, NGOs, international organization etc. Ability and capacity of those institutions should be as high as they are capable to mitigate the disaster.
refers the measures that ensure the organized mobilization of personnel, funds, equipment, and supplies within a safe environment for effective relief. Preparedness lessens the severity of disasters by preparing people for disaster, developing plans to ensure an effective response and recovery and training people to implement plans after a disaster occurs.
Preparedness
Preparedness Includes: (3)
1) Forecasting and Warning for Different Hazards.
2) Emergency Preparedness
- Organized personnel for monitoring, alert and evacuation
- Medical team
- Search and rescue team
- Availability of food reserve
-Emergency monetary fund and seed reserve - Distribution of disaster supplies and equipment
3) Education, Training and Public Awareness
Weather Forecast and Early Warning
is the application of science and technology to predict the state of the atmosphere for a given location. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using scientific understanding of atmospheric processes to project how the atmosphere will change.
Forecast
Weather Forecast and Early Warning
Various types of tools like Barometer, Radiosonde, Satellite (Geostationary and Polar Orbit), Radar, and other equipments.
Tools
Weather Forecast and Early Warning
is a major element of disaster risk reduction. It prevents loss of life and reduces the economic and material impact of disasters. early warning systems can be used to detect a wide range of events, such as vehicular collisions, missile launches, disease outbreaks, and so forth.
To be effective, early warning systems need to actively involve the communities at risk, facilitate
public education and awareness of risks, effectively disseminate alerts, and warnings and ensure there is constant state of preparedness.
Early Warning System
Tasks Related to Early Warning (4)
1) Communication
2) Indigenous Knowledge
3) Media
4) Instruction
Types of Early Weather and Forecasting: Based on Duration : (3)
1) Short Range: 48-72 Hours (e.g. Cyclone, Hurricane, Bombing, Flood etc.)
2) Medium Range: 3 Days to 3 Weeks (e.g. Cold and Heat Wave, Floods etc.)
3) Long Range: Over a Season (El-Nino, La-Nina etc.)
Types of Early Weather and Forecasting: Based on Purposes: (4)
1) Aviation
2) Shipping
3) Local
4) Agricultural Base
Level of Preparedness: (4)
- Family
- Community
-Volunteering activities
-protesting environmental degradation
-awareness building
-Emergency steps - National: Developing principles and laws, executing rules, funding etc.
- International/ Regional: Seminar, Conference, Exchange of Technology and knowledge.
