What Are Disasters?
Disasters are severe disturbances in a community's functioning that exceed its capacity to adapt using its own resources. Disasters can occur due to natural hazards, technological hazards, or those caused by humans, as well as various factors that affect a community's vulnerability and exposure to risk, which can have devastating effects on people and communities.
It is likely that the frequency, complexity, and severity of these risks will increase in the future due to factors such as climate change, displacement, conflict, rapid and unplanned urbanization, technological risks, and public health emergencies. Therefore, we can and should prevent disasters by helping communities prepare for them, reduce their risks, and increase their resilience.
About 90% of disasters worldwide are due to weather, climate, or water-related hazards. While natural hazards cannot be avoided, early warnings can reduce the scale of a disaster. For example, if people know in advance that a hurricane or cyclone is forming nearby, they can seek shelter.
The global monitoring system of the World Meteorological Organization (WMO) helps reduce disaster risks by providing information for early warnings and emergency response. This has contributed to reducing deaths from natural hazards in recent decades.
Causes of Natural Disasters
The causes of natural disasters vary from one type to another, but they can be broadly categorized into two main groups:
- Natural Causes: These are reasons that occur due to natural phenomena, such as tectonic plate movements, volcanic eruptions, or climate changes.
- Human Causes: Human-related causes of natural disasters include:
- Deforestation: Removing forests eliminates the natural protective layer of the earth, making it more susceptible to natural disasters like floods and landslides.
- Overhunting: Overhunting leads to the removal of animals from their natural habitats, disrupting the ecological balance and increasing the risk of natural disasters.
- Climate Change: Human-induced climate change, resulting from emissions from factories, leads to rising temperatures and changes in precipitation patterns, increasing the risk of natural disasters such as droughts and floods.
Natural Disaster Risks
Firstly: Loss of Lives
Loss of lives is one of the most dangerous risks associated with natural disasters. Natural disasters can cause the death of hundreds or even thousands of people due to several factors, such as:
- Direct Injuries: Natural disasters like earthquakes and hurricanes can cause direct injuries to people, such as falls, wounds, or bruises.
- Indirect Injuries: Natural disasters like floods and droughts can cause indirect injuries to people, such as contracting diseases, hunger, or displacement.
Secondly: Property Losses
Natural disasters can destroy homes, businesses, and other infrastructure, leading to significant financial losses. Disasters like earthquakes, hurricanes, and floods can completely or partially destroy properties.
Thirdly: Environmental Damage
Natural disasters can destroy forests and wildlife, disrupting the ecological balance. Disasters like wildfires and landslides can significantly destroy forests and wildlife.
Prevention of Natural Disasters
Natural disasters cannot be completely prevented, as they occur due to natural phenomena. However, steps can be taken to mitigate their effects. This can be achieved by:
- Building Disaster-Resistant Infrastructure: Infrastructure such as buildings and dams can be constructed in a way that makes them resistant to natural disasters. For example, buildings can be built using materials that are resistant to earthquakes or floods.
- Developing Emergency Plans for Disasters: Emergency plans can be developed for natural disasters to help people stay safe in the event of a disaster. These plans can include information on how to evacuate during a hurricane or how to get assistance during a flood.
- Raising Public Awareness about Natural Disasters: Public awareness about natural disasters can be promoted to help people prepare for them. Awareness campaigns can include information about the types of natural disasters that occur in the area and how to stay safe during them.
Sendai Framework for Disaster Risk Reduction
The Sendai Framework for Disaster Risk Reduction is a voluntary agreement among member states, spanning the years from 2015 to 2030. Its primary goal is to reduce disaster risks and the associated losses of lives, livelihoods, homes, wealth, and health. The United Nations Office for Disaster Risk Reduction coordinates the implementation of the Sendai Framework.
Key Objectives of the Sendai Framework
- Substantially Reduce Global Disaster Mortality: By 2030, aim to reduce the average global mortality rate per 100,000 people in the decade 2020-2030 compared to the period 2005-2015.
- Substantially Reduce the Number of Affected People Globally: By 2030, aim to reduce the average global number of affected people per 100,000 in the decade 2020-2030 compared to the period 2005-2015.
- Reduce Direct Economic Losses in Relation to Global GDP: By 2030, reduce direct economic losses from disasters relative to global GDP.
- Substantially Reduce Disaster Damage to Critical Infrastructure and Disruption of Basic Services: By 2030, reduce damage to critical infrastructure and disruption of basic services, including health and educational facilities, by enhancing their resilience.
- Substantially Increase the Number of Countries with National and Local Disaster Risk Reduction Strategies: By 2020, significantly increase the number of countries with national and local disaster risk reduction strategies.
- Substantially Enhance International Cooperation to Developing Countries: By 2030, significantly enhance international cooperation to provide adequate and sustainable support for developing countries to complete their national actions to implement the current framework.
- Substantially Increase the Availability of and Access to Multi-Hazard Early Warning Systems and Disaster Risk Information and Assessments: By 2030, significantly increase the availability and accessibility of multi-hazard early warning systems and disaster risk information and assessments for people.
Organizations Working in Disaster Risk Reduction
- FAO (Food and Agriculture Organization): The Food and Agriculture Organization of the United Nations leads international efforts to eradicate hunger. FAO serves both developed and developing countries as a neutral forum where all nations meet on an equal footing to negotiate agreements and discuss policies.
- International Organization for Migration (IOM): Established in 1951, the International Organization for Migration is a leading intergovernmental organization in the field of migration. It works closely with governmental and non-governmental partners to ensure the organized and humane management of migration, promote international cooperation on migration issues, and provide practical solutions to migration problems. IOM also offers humanitarian assistance to migrants in need, including refugees and internally displaced persons.
- UN-Habitat (United Nations Human Settlements Programme): UN-Habitat is the United Nations agency for human settlements. Mandated by the UN General Assembly to promote socially and environmentally sustainable towns and cities, it aims to provide adequate shelter for all.
- UN-Water: The United Nations Water Committee coordinates the efforts of UN agencies and international organizations working on water and sanitation issues.
