Strategies and actions for reducing, managing, and recovering from impacts of disasters. With reference to infrastructure development, resilience pathways refer to perspectives, strategies and actions that help infrastructure systems to withstand and recover from disasters in a timely and efficient manner with minimal impact on essential basic structures and functions.
1. Climate resilient development pathways (CRDPs) are trajectories that strengthen sustainable development and efforts to eradicate poverty and reduce inequalities while promoting fair and cross-scalar adaptation and resilience to a changing climate. They raise the ethics, equity and feasibility aspects of the deep societal transformation needed to drastically reduce emissions to limit global warming (e.g., to well below 2°C) and to achieve desirable and livable futures and well-being for all.

Resilience of Water Distribution Systems (WDS)
Ensuring a consistent and reliable supply of water is a crucial challenge facing modern societies. The design and implementation of a Water Distribution System (WDS) plays a critical role in this regard, particularly with regard to resilience. One of the aspects of resilience in a WDS argues for the presence of alternative paths for water supply to customers, such as parallel pipes or dense grid network configurations.
Additionally, redundant network connectivity, such as emergency pipe connections between district metering areas (DMAs), can provide access to water stored in neighbouring tanks during emergencies. The physical strength of tanks and pipelines can also play a critical role in preserving water resources during seismic events. Furthermore, the availability of sufficient emergency response staff and teams can enable rapid response to any pipe or pump failures, ensuring continued availability of water even in adverse conditions.
