Risk and resilience lessons from Venice

In the history of disasters in Venice, there are implications for modern times in terms of complex systems management and emerging threats, in particular from examples of risk management and resilience achieved by the Venetian state during outbreaks of the plague. In fourteenth century Venice, risk assessment the way we practice it today would fail to provide meaningful recommendations to reduce the casualty rate of the plague epidemic because the cause and transmission of the disease was not understood. Instead, a set of systemic actions across the social, economic, and transportation networks of the city taken by officials and doctors eventually slowed and arguably stopped the spread of the disease. These latter actions are an early example of what is now considered resilience management. Resilience management improves a complex system’s ability to prepare, absorb, recover, and adapt to unexpected threats and does so by address the capabilities at a system, rather than component, level. Resilience management can be a guide to addressing current issues of population growth and rising sea level in modern day Venice and across the globe. This paper calls for integration of resilience assessment in comprehensive risk and resilience management framework.     

A value-based approach to infrastructure resilience

This paper includes the findings of MMI Thornton Tomasetti’s investigation into the measurement of resilience within infrastructure using systems thinking and focussed on value delivery. This paper provides a review of current practise across critical infrastructure sectors, based on a series of interviews undertaken with stakeholders from various UK infrastructure organisations. Gaps and opportunities were identified and an outline for a value-based approach to diagnosing, measuring and building resilience suggested. The performance of critical infrastructure sectors was also comparatively assessed using the suggested approach value metrics.     

Social equity in urban resilience planning

ABSTRACT

A growing number of cities are incorporating resilience into their plans and policies to respond to shocks, stresses, and uncertainties. While some scholars advocate for the potential of resilience research and practice, others argue that it promotes an inherently conservative and neoliberal agenda, prevents systemic transformations, and pays insufficient attention to power, politics, and justice. Notably, critics of the urban resilience agenda argue that policies fail to adequately address social equity issues. This study seeks to inform these debates by providing a cross-sectional analysis of how issues of equity are incorporated into urban resilience planning. We develop a tripartite framework of equity that includes distributional, recognitional, and procedural dimensions and use it to analyse the goals, priorities, and strategies of formal resilience plans created by member cities of the Rockefeller Foundation’s 100 Resilient Cities programme. Our analysis reveals considerable variation in the extent to which cities focus on equity, implying that resilience may be more nuanced than some critics suggest. There are, however, clear areas for improvement. Dominant conceptions of equity are generally tied to a distributional orientation, with less focus on the recognitional and procedural dimensions. We hope our conceptual framework and lessons learned from this study can inform more just resilience planning and provide a foundation for future research on the equity implications of resilience.     

Converging disciplinary understandings of social aspects of resilience

Resilience thinking has developed separately in the bodies of literature on social-ecological systems, and that published principally within developmental psychology and mental health on the resilience of individuals. This paper explores what these bodies of literature might learn from the other towards a more integrated and enriched understanding of both social-ecological systems and social resilience. The psychology-based literature recognises a strong set of factors that enhance the strengths of individuals and communities, but lacks a sophisticated integration of the physical environmental context. The social-ecological systems literature offers an excellent foundation in complex adaptive systems, but tends to superimpose ecological concepts of system function onto the human domain, and needs to include an array of core social science concepts that are important to a full understanding of social-ecological systems. An example on north eastern Australia suggests how a converged understanding of social resilience could assist managers to acknowledge, enhance and foster social resilience in linked social-ecological systems.     

A measurement of community disaster resilience in Korea

Building a community that is resilient to disasters has become one of the main goals of disaster management. Communities that are more disaster resilient often experience less impact from the disaster and reduced recovery periods afterwards. This study develops a methodology for constructing a set of indicators measuring Community Disaster Resilience Index (CDRI) in terms of human, social, economic, environmental, and institutional factors. In this study, the degree of community resilience to natural disasters was measured for 229 local municipalities in Korea, followed by an examination of the relationship between the aggregated CDRI and disaster losses, using an ordinary least squares (OLS) regression method and a geographically weighted regression (GWR) method. Identifying the extent of community resilience to natural disasters would provide emergency managers and decision-makers with strategic directions for improving local communities' resilience to natural disasters while reducing the negative impacts of disasters.     

Contributions of green infrastructure to enhancing urban resilience

After briefly reviewing key resilience engineering perspectives and summarising some green infrastructure (GI) tools, we present the contributions that GI can make to enhancing urban resilience and maintaining critical system functionality across complex integrated social–ecological and technical systems. We then examine five key challenges for the effective implementation of GI that include (1) standards; (2) regulation; (3) socio-economic factors; (4) financeability; and (5) innovation. We highlight ways in which these challenges are being dealt with around the world, particularly through the use of approaches that are both context appropriate and socially inclusive. Although progress surmounting these challenges has been made, more needs to be done to ensure that GI approaches are inclusive and appropriate and feature equally alongside more traditional ‘grey’ infrastructure in the future of urban resilience planning. This research was undertaken for the Resilience Shift initiative to shift the approach to resilience in practice for critical infrastructure sectors. The programme aims to help practitioners involved in critical infrastructure to make decisions differently, contributing to a safer and better world.     

Design for resilience in infrastructure distribution networks

The recognition that resilience is a critical aspect of infrastructure security has caused the national and homeland security communities to ask “How does one ensure infrastructure resilience?” Previous network resilience analysis methods have generally focused on either pre-disruption prevention investments or post-disruption recovery strategies. This paper expands on those methods by introducing a stochastic optimization model for designing network infrastructure resilience that simultaneously considers pre- and post-disruption activities. The model seeks investment–recovery combinations that minimize the overall cost to a distribution network across a set of disruption scenarios. A set of numerical experiments illustrates how changes to disruption scenarios probabilities affect the optimal resilient design investments.     

Determinants of state mining enterprise resilience in Latin America

The performance of many state-owned mining firms in Latin America has been disappointing. There is at least one interesting exception: Chile's Codelco has been more resilient than, say, its counterparts in Bolivia and Peru. The state mining firms of Bolivia and Peru were decapitalized by low autonomy, flawed tax policies and weak macroeconomic policies - even as the importance of such firms in the economy increased. In contrast, Codelco benefited from an orthodox macroeconomic policy which sensibly, if belatedly, adopted a mineral stabilization fund. It also enjoyed a more profit related tax regime and somewhat higher commercial autonomy. Nevertheless, the Chilean experience requires some important qualifications before it can be used as a model for other developing countries.     

Improving communication resilience for effective disaster relief operations

The objective of this paper is to identify strategies to improve the resilience of interagency communication between relief organizations and the community when dealing with an emergency. This research draws from frameworks including information theory, organization design, and how the private sector has learned and evolved from the challenges of information flow to provide guidance to disaster relief agencies. During times of emergency, private organizations as well as public authorities must coordinate in real time to create an effective response. When coordination is absent, failure results, as was seen after Hurricane Katrina and the Haiti Earthquake. Using data that the authors collected immediately after these disasters, two case studies of systemic failure are presented to extract lessons that might be used to improve communication resilience through coordination between parties in humanitarian relief operations. Recent emergency response trends are identified, and the paper argues that the persistence of response failures is not surprising, in part because response organizations normally operate independently, and their operations evolve at different rates. As a result, the organizational interfaces that enable rapid integration during a disaster naturally degrade and may be weak or absent. Integrating the literature on information processing theory and organization design with the data from the two case studies, the paper proposes that increasing the resilience of disaster response systems can be achieved by (1) improving the interoperability and information flow across organizational boundaries; (2) increasing the synergies between organizations on adapting new technology such as social media for the coordination of structured and unstructured data for use in decision-making, and (3) increasing the flexibility of relief organizations to use external resources from areas not affected by disasters on an opportunistic basis. The paper concludes by discussing resilience enhancing solutions including boundary spanning investments and argues that effective emergency response does not result from sporadic or intermittent efforts but rather requires sustained investment, continuous monitoring, and data collection.

On some aspects of ecological resilience and the conservation of species

The importance of the notion of resilience in determining the static and the intertemporal behaviour of jointly determined ecological-economic systems has long been recognized by ecologists. This notwithstanding, there are very few formal studies of such systems which explicitly analyse the ecological and the economic aspects of the problem. Consequently, this paper has two objectives. First, a new stationary probability-based method is proposed to characterize the notion of ecological resilience. Next, this characterization is used to study the problem of optimal species conservation.     

Some lessons for resilience from the 2011 multi-disaster in Japan

With the goal of resilience becoming ever more present in diverse policy discourses, it is important to reflect critically on its meaning and realisation. In this viewpoint, we re-emphasise that understanding the systemic nature of social and ecological interactions and interdependencies is fundamental to developing resilience to shocks and stresses in whatever context they materialise. Through the lens of the 2011 Japanese multi-disaster, we reflect on some of the difficulties in generating knowledge to underpin resilience-building processes and illustrate some dilemmas inherent in seeking to cultivate resilience in practice. Events in Japan underscore the complex vulnerabilities of place in multi-hazard scenarios and highlight, in particular, the choices to be made in determining which systemic interactions are to be imagined, characterised, assessed and forewarned and which are not. These events also emphasise that while resilience ultimately must be located where consequences are felt, strategies for a resilient future have to take on the multi-scale interactions and tensions within which local processes are embedded. There are dangers, we argue, in thinking about resilience in overly simple and non-systemic ways and in responding to these challenges only as a matter of extended techno-managerial competence.     

Developing an integrative urban resilience capacity index for plan making

Urban resilience assessment can help planners understand the status of resilience in an urban system and identify needs for improving resilience capacities. The issues related to urban resilience are complex because of multiple urban system components, threats from different sources, and uncertainty of the future. Urban resilience theories have progressed to consider an urban system as an integrated complex system; however, urban resilience assessments are inconsistent and underdeveloped in assessing an integrated urban system for different threats at various uncertainties. In an effort to address this deficiency, we propose to develop an Integrative Urban Resilience Capacity Index (IURCI) for assessing urban resilience capacity for all threats. To improve the quality of urban resilience assessment, the IURCI considers urban physical form, spatial structure, preparation for future, and performance after plan implementation to measure resilience capacities of absorption, mitigation, and adaptation. It is built in a Scenario-Based Planning Support System (SB-PSS). The SB-PSS is a framework and an open system that integrates IURCI with scenario generation, modeling, and assessment to inform the public, planners, and other stakeholders about the consequences of different planning policies and to assist them make decisions for implementing a preferred scenario.
