The correct answer is: b) Minimizing disaster impact.
Early warning systems are designed to provide timely and accurate information about an impending disaster, so that people can take action to protect themselves and their property. This can include evacuation, sheltering in place, or taking other measures to reduce the risk of injury or death.
Early warning systems can be used to mitigate the impact of a wide range of disasters, including floods, earthquakes, tsunamis, and hurricanes. They can also be used to warn people about other hazards, such as wildfires, landslides, and chemical spills.
Early warning systems are an essential part of disaster risk reduction. They can save lives and property, and they can help to reduce the economic and social impact of disasters.
Here is a brief explanation of each option:
- Option a) Preventing natural hazards is not the main role of early warning systems. Early warning systems can help to reduce the impact of natural hazards, but they cannot prevent them from happening.
- Option b) Minimizing disaster impact is the main role of early warning systems. Early warning systems can help to save lives and property by providing timely and accurate information about an impending disaster.
- Option c) Reforestation is not the main role of early warning systems. Early warning systems can help to reduce the impact of natural hazards, but they cannot reforest an area that has been damaged by a disaster.
- Option d) Climate change mitigation is not the main role of early warning systems. Early warning systems can help to reduce the impact of climate change, but they cannot mitigate climate change itself.
