Resilience in urban areas

The increasing urban population puts added pressure on housing, transport, water supply and other systems and services. Urban resilience is when the systems and services of the town or city survive shocks and stresses, the people and organisations are able to accommodate these stresses into their day-to-day decisions, and the city’s institutional structures continue to function (Asian Development Bank, 2014). There is no single action that will make a city resilient to climate change. Resilience is developed through many actions, which build upon each other and where the focus is on preparation for disaster rather than response to it. This means that plans for resilience should be included as part of any urban development plan. The Asian Development Bank (2014) identifies the following guiding principles for urban resilience:

1. Combine ‘hard’ and ‘soft’ measures in the plan: this highlights that the actions and behaviours (soft measures) of individuals, communities and institutions are as critical to city resilience as protecting physical structures such as buildings and transport networks (hard measures). Resilience needs regulations, information systems and social networks.
2. Engage multiple stakeholders: cities are diverse and complex, so engaging businesses, civil society and government is necessary to build resilience and to form city-wide plans of preparedness.
3. Enlist different geographic and governance scales: cities have links with rural areas, internationally, and with each other. These links can be vital for building resilience, providing relief and sharing information about best practice.
4. Look to the future: planning processes have to address current issues but should also consider possible future situations, even though they may be uncertain.
5. Use local expertise: people with local knowledge can exchange information with external experts to build long-term adaptive capacity.
6. Build leadership: effective resilience needs strong leadership and accountability.
7. Focus on vulnerable communities: meaningful urban resilience must meet the needs of poor and vulnerable households who lack the resources available to others.

Building communication networks and sharing best practice is an important aspect of these principles. A

Early warning systems

An important element of resilience is having contingency plans that can be put into action if disaster strikes. These are plans that provide answers to such questions as ‘what if the town floods?’ or ‘what if there’s an earthquake?’ To be effective these plans need an early warning system to alert people of impending danger to trigger avoidance actions and reduce risk. Early warning systems refer to a set of capacities needed to generate and disseminate timely and meaningful warning information to enable individuals, communities and organisations threatened by a hazard to prepare and to act appropriately and in sufficient time to reduce the possibility of harm or loss (UNISDR, 2009). Or, to put it more simply, early warning systems are designed to let people know when something bad is going to happen so they can prepare themselves and try to avoid harm. An early warning system can bring safety, security and peace of mind.

Early warning systems make contingency planning and evacuation procedures more precise and help put people and their property and livelihoods out of harm’s way. In low-income countries, there is a high degree of vulnerability to natural and climate hazards, particularly among the poorest households and those located in remote areas. Communication to these and other people through an early warning system can help reduce disaster risk by improving preparedness and giving greater protection to people and their livelihoods. Figure 12.4 demonstrates the essential elements of an early warning system.

An early warning system works best as part of an integrated and unified risk management framework. Most low-income countries are moving forward with plans to build adaptive capacity and improve resilience to climate change. We conclude this study session with a comment on the ultimate goal for resilience strategies. Whereas early notions of resilience spoke of systems returning to a stable and pre-existing state, there is now an acceptance that this is rarely possible, and perhaps not even desirable. Instead, more recent ideas have emphasised the system’s capacity to reorganise, change and adapt to threats. This is because episodes of stress can be recurrent events, and returning to the situation that existed before the disturbance may simply be a return to vulnerability. Change, however, can build greater resilience in order to be less reactive and more proactive.
