Hazards and Disaster Resilient Cities II.
Synopsis
The population of people living in areas exposed to hazard are increasing. Approximately half of the 6 billion people live in cities. It is estimated that by 2025 the world population will be 8 billion and 60% will live in cities. 40% of these cities are located in coastal areas and in areas exposed to meteorological and geological hazards.
From past to present, natural disasters have affected cities the most. The most important reason for this is the population density and construction in cities. This situation, together with the acceleration in population growth in the last century, has greatly increased the vulnerability of cities.
When all these facts are taken into account, increasing the resilience of cities becomes a necessity. Resilience in disasters; It is the ability of a system or society exposed to a hazard to absorb, restore and recover from the effects of the hazard in a timely and effective manner, including the protection and renewal of its basic structures (Varol and Kırıkkaya, 2017). A resilient city is; By definition, it must have the ability to resist all the negativities that a disaster may cause, including post-disaster recovery efforts.
To understand the resilience of complex urban systems, it is necessary to examine the interconnected networks of physical and social components. Physical components form the skeleton of the system, such as buildings and infrastructure; Social components such as community and open space represent the soul of the system. Interactions between these components are critical factors that determine how urban systems respond to natural disasters.
Natural disasters are the result of a natural hazard affecting people and or the environment. People's vulnerabilities and unsuccessful disaster and emergency risk management lead to this outcome. The magnitude of losses is related to resilience and capacity against disasters. If capacity and resilience are high and vulnerabilities are low, dangers do not turn into disasters or are overcome with minimal damage.
In a period when the frequency of natural disasters is increasing worldwide, the resilience of urban systems against such events is becoming increasingly important and comes to the fore. The design and planning of disaster-resilient cities is critical for the safety of both current and future generations.
