1. Basic Concept of Disaster and Disaster Risk Lesson 1:

2. The Concept of Disaster and Disaster Risk The terminologies listed below are defined by the United Nations Office for Disaster Risk Reduction (UNDRR) , also known as the United Nations International Strategy for Disaster Reduction (UNISDR).

3. What is DISASTER? A disaster is defined as a serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure , vulnerability, and capacity, that may lead to one or more of the following : human , material, economic, and environmental losses and impacts. An event is already a disaster if a hazard has already affected a population making them vulnerable .

4. What is DISASTER RISK? A disaster risk is the potential loss of life, injury or destroyed or damaged assets which could occur to a system , society, or a community in a specific period , determined probabilistically as a function of hazard, exposure, vulnerability, and capacity . The disaster risk formula is shown below:

5. Hazard A hazard is a process, phenomenon, or human activity that may cause loss of life, injury or other health impacts, property damage, social and economic disruption or even environmental degradation.

6. Exposure An exposure is the situation of people, infrastructure, housing, production capacities and other tangible human assets located in hazard-prone areas.

7. Vulnerability Vulnerability is a condition determined by physical, social, economic, and environmental factors or processes which increases the susceptibility of an individual, a community, assets or systems to the impacts of hazards.

8. To determine disaster risk, the capacity of the community must be analyzed. Capacity is the combination of all strengths, attributes, and resources available within an organization, community, or society to manage and reduce disaster risks and strengthen resilience. The capacity of a community may include the knowledge and skills of people, leadership and management of the local government, and the infrastructure and facilities available to the community.

9. Nature of Disaster 1. Natural Hazards and Disasters are the results and outcomes of naturally occurring processes that occurred throughout Earth's history. Examples: Flood, volcanic eruption, insect infestation, tropical cyclone. earthquake, tsunami, landslide, hurricane, tornado, sinkhole, drought, storm surge etc. 2 . Man-made/Human-induced/Anthropogenic Hazards and Disasters occur as a result or an outcome of human actions and interactions with other people and the environment. Examples: Chemical threat, hazardous material, nuclear blast, cyber-attack, terrorism, civil unrest, bioweapon etc.

10. Disaster Risk Drivers Disaster risk drivers are factors that promote or increase the risk of a disaster. The following are some disaster risk drivers .. 1. Climate change this can amplify disaster risk while weakening the resilience of the community . 2. Poverty extreme poverty equates to greater disaster impact 3. Socio-economic inequality can result to limited capacity of households and communities to manage the risk and improve their resilience 4 . Increase population density/growth-the higher the population, the greater vulnerability to disasters .

11. 5. Rapid and unplanned urbanization can result to an increased severity of disasters 6. Environmental degradation . can reduce the environmental capacity to provide social and ecological needs 7. Lack of awareness households, communities, and societies who have lack of awareness on disasters are not disaster prepared thus can aggravate disaster risk 8. Weak governance inefficient, and incompetent protection of human rights, and failure to provide public services can happen due weak governance
