Major Findings of the Interconnected Disaster Risks Report 2023
About the Report
- The UN Interconnected Disaster Risks Report is an annual publication by the United Nations University- Institute for Environment and Human Security (UNU-EHS).
- First published in 2021, it examines the interconnections between various disasters and human actions.
Risk Tipping Points
- The report introduces the concept of “risk tipping points,” where socio-ecological systems can no longer buffer risks, leading to catastrophic impacts.
Environmental Tipping Points
- The world is nearing six environmental tipping points, including:
- Depletion of aquifers, which provide water for over 2 billion people, with 70% used for agriculture.
- Over-extraction in areas like Saudi Arabia, depleting over 80% of its aquifer and impacting food security.
- Groundwater depletion in the Indo-Gangetic basin in India, with the northwestern region facing limited availability by 2025.
- Accelerated species extinction due to human activities, leading to ecosystem collapses.
- Glacial melting at double the rate due to global warming, with a projected loss of 50% of glaciers by 2100.
- Risk to 90,000+ glaciers in the Himalayas, Karakoram, and Hindu Kush mountains, affecting 870 million people.
Space Debris Problem
- The growing number of satellites in space has led to a space debris problem.
- Only 25% of objects in orbit are active satellites, with about 130 million smaller, untrackable debris pieces.
- These debris pieces pose a collision risk to operational satellites, creating a hazardous orbital environment.
Deadly Heat Waves
- Climate change is causing more deadly heat waves, with high temperatures and humidity making it difficult for the body to cool down.
- Wet-bulb temperatures exceeding 35°C for over six hours can lead to organ failure and brain damage.
- Expected to affect over 70% of the global population by 2100.
Severe Weather and Economic Impact
- Frequent severe weather events have caused a sevenfold increase in damages since the 1970s, resulting in USD 313 billion in losses in 2022.
- Insurance costs are rising due to climate change, making coverage unaffordable for many.
- Some insurers are leaving high-risk areas, rendering regions “uninsurable,” as seen in Australia with increased flood risk.
Common Driver: Climate Change
- Climate change, driven by increased greenhouse gas emissions, acts as a common driver of tipping points, impacting glacier melting, extreme weather events, and changes in the insurance risk landscape.
- These interconnected environmental issues can trigger feedback loops, like rising sea levels from glacier melt, intensifying coastal flooding, and increasing the demand for disaster insurance.
- Ultimately, these tipping points have significant socioeconomic consequences.
Major Drivers of Increasing Disaster Risks
- Occurs without adequate planning and infrastructure development.
- As cities expand, more people and property are exposed to hazards like floods and earthquakes, increasing vulnerability to disasters.
- Deforestation, soil erosion, and pollution weaken natural ecosystems.
- Reduced ability of ecosystems to act as buffers against disasters amplifies the impacts of hazards.
- Inadequately built or maintained infrastructure, such as bridges, buildings, and roads, can crumble during disasters, resulting in significant economic and social losses.
Inadequate Land Use Planning
- Poor land use planning can lead to communities settling in high-risk areas, such as floodplains or wildfire-prone regions.
- This contributes to increased exposure to disasters.
Mismanagement of Water Resources
- Mismanagement can lead to droughts, water scarcity, and flooding.
- These issues have far-reaching consequences for food security, economies, and communities.
- As the world becomes more interconnected, disruptions in one area can have cascading effects globally.
- This interconnectedness can propagate the economic and social impact of disasters.
Solutions to Mitigate Disaster Risk
The UN Interconnected Disaster Risks Report 2023 provides a four-category framework for classifying and prioritizing solutions to address disaster risks:
- These actions aim to prevent disasters by slowing them down using current methods.
- Example: Implementing strict building codes and land-use regulations to prevent major damage from disasters.
- These actions focus on preventing disasters by making significant changes in how things are done.
- Example: Transitioning from fossil fuel-based energy production to renewable energy sources (like solar and wind) to avoid the risks associated with climate change.
- These actions prepare us to handle disasters by buying more time to respond effectively.
- Example: Developing advanced early warning systems for tsunamis to buy time for people to evacuate and prepare for the disaster.
- These actions involve making significant changes to how we do things to adapt to disasters.
- Example: Implementing coastal zoning policies and restoring natural barrier ecosystems (like mangroves) to adapt to rising sea levels and transform coastal protection strategies.
