Understanding disaster risk: Risk drivers

Risk is influenced by the decisions we make. From climate change to poor urban planning, it is critical to understand and address risk drivers to curb disaster risk.

Climate change
Climate change can increase disaster risk in a variety of ways - by altering the frequency and intensity of hazard events, affecting vulnerability to hazards, and changing exposure patterns.

Environmental degradation
Environmental degradation is both a driver and consequence of disasters, reducing the capacity of the environment to meet social and ecological needs.

Globalized economic development
This has increased vulnerability to disasters in some cases, whilst increasing exposure to hazards in others as more (and often more valuable) assets are developed in hazard-prone areas.

Poverty and inequality
Poverty is both a driver and consequence of disasters, and the processes that further disaster risk related poverty are permeated with inequality.

Poorly planned urban development
Whether or not disaster risk is factored into investment decisions in urban development will have a decisive influence on the future of disaster risk reduction.
