Universal resilience patterns in complex networks

"Resilience, a system's ability to adjust its activity to retain its basic functionality when errors, failures and environmental changes occur, is a defining property of many complex systems. Despite widespread consequences for human health, the economy and the environment, events leading to loss of resilience—from cascading failures in technological systems to mass extinctions in ecological networks—are rarely predictable and are often irreversible. These limitations are rooted in a theoretical gap: the current analytical framework of resilience is designed to treat low-dimensional models with a few interacting components, and is unsuitable for multi-dimensional systems consisting of a large number of components that interact through a complex network. Here we bridge this theoretical gap by developing a set of analytical tools with which to identify the natural control and state parameters of a multi-dimensional complex system, helping us derive effective one-dimensional dynamics that accurately predict the system's resilience. The proposed analytical framework allows us systematically to separate the roles of the system's dynamics and topology, collapsing the behaviour of different networks onto a single universal resilience function. The analytical results unveil the network characteristics that can enhance or diminish resilience, offering ways to prevent the collapse of ecological, biological or economic systems, and guiding the design of technological systems resilient to both internal failures and environmental changes."

Transition Towns in Aotearoa New Zealand

"Transition Towns initiatives are part of a vibrant, international grassroots movement that brings people together to explore how we–as communities – can respond to the environmental, economic and social challenges arising from climate change, resource depletion and an economy based on growth. We don't look for anyone to blame or anyone to save us, but believe our communities have within themselves the innovation and ingenuity to create positive solutions to the converging crises of our time. We believe in igniting and supporting local responses at any level and from anyone–and aim to weave them together into a coordinated action plan for change towards a lower energy lifestyle. By building local resilience, we will be able to collectively respond to whatever the future may bring in a calm, positive and creative way. And by remembering how to live within our local means, we can rediscover the spirit of community and a feeling of power, belonging and sharing in a world that is vibrant, just and truly sustainable."
