Sea defence policy in England has proven contentious in the early twenty-first century, with government willing to defend the coast only where it is considered cost effective and not minded to compensate people for any resulting abandonment of homes. Additional focus is brought to this position by the 2015 United Nations Sustainable Development Goals (SDGs) which reflect a growing emphasis on climate change effects and other environmental hazards, and the wellbeing of the current generation and those to come. This requires policy makers to seek to balance economic, social and environmental dimensions, and to tackle inequalities; with a central commitment of the goals to "leave no one behind". Subsequent to publication of the SDGs, England was promised a revolution in the government's approach to Flood and Coastal Erosion Risk Management (FCERM). This paper seeks to understand the nature of this revolution with particular regard to extant issues around just governance. It finds that policy fails to deal with issues over the local acceptability of proposals for change and the bearing of risk, and instead lies principally in the elevation of the problematic concept of resilience and an accompanying ambivalence towards ideas of sustainability and sustainable development. International agreement that compensation should be paid to those countries suffering the worst effects of climate change, including sea level rise, suggests that adoption of a similar approach to vulnerable homeowners might be the more appropriate revolution and bring policy more into line with the aspirations of the SDGs.

Recent national level guidelines and research efforts increasingly suggest the use of resilience and sustainability concepts for natural hazard mitigation and recovery planning at the regional and community levels. This paper aims to distinguish and compare the two abstract concepts in the context of road networks recovering from a hazard event since resilience and sustainability metrics are often interchangeably adopted and can lead to inaccurate equivalencies between the two concepts. A spectrum of resilience and sustainability metrics are defined herein and a research methodology is described to evaluate them probabilistically. A case study demonstration on the road network in the Memphis Metropolitan Statistical Area (MMSA) for a probabilistic suite of earthquake scenarios shows that the correlation between network resilience and sustainability is dependent on the hazard level as well as the graphical abstraction of the real road network. While some correlations are observed between temporal sustainability metrics, such as missed trips and traffic emissions, and resilience metrics, like total travel distance and time, the correlation weakens as the network resolution becomes more sparse. These results show that while for dense networks, time-evolving travel time and travel distance may be used as proxy measures for hazard sustainability evolution, for sparsely connected networks, hazard resilience and post-hazard sustainability remain relatively distinct.

This paper discusses the contradictions and tensions in the governance of international migration that the pandemic has exposed. It starts by defining the pandemic emergency as a wicked problem. Even though wicked problems usually do not have solutions, we argue that building resilience and sustainability as key features in migration governance can help address this wicked challenge. We look at three types of resilience: situated, structural and systemic and discuss the extent to which they may form the basis of sustainable migration governance. [ABSTRACT FROM AUTHOR]

Cities and neighbourhoods are changing rapidly. While rapid change is accepted, it is less clear how to understand and analyse change and steer it towards a more sustainable trajectory. This paper focuses on the transformation of a particular street in Mamelodi, situated in Pretoria (capital city of South Africa). Utilizing a resilience lens, we unpack the various cycles of adaptation evident in the street. Our analysis shows that the transformation of Tsweu Street broadly followed the phases of the adaptive cycle, namely rapid growth, conservation, release and reorganization and incorporated three dimensions of resilience, namely social or community, spatial and institutional resilience. We argue that resilience thinking offers a mechanism to understand and analyse change at various scales, including the street level and that this provides planners with a tool to work with change through the application of appropriate measures at the relevant time to maximize their impact.

The increase in urbanization and climate change brings new challenges to the cities' sustainability and resilience, mainly related to flood and drought events. Among these challenges, it can be highlighted the physical and health damage to the population, interruption of water, energy and food supply services, damage to basic infrastructure, economic losses and contamination of urban rivers. To contribute to the increase of resilience in urban centers, LID practices have been used as a new approach of mitigation and adaptation within urban drainage systems, aiming at runoff retention, peak flow attenuation, pollutant removal and ecosystem services restoration (e.g., resources recycling, carbon sequestration, thermal comfort and landscape integration). These different mitigation purposes and complementary benefits provided by LID practices can be related to the different Sustainable Development Goals (SDG) presented by the United Nations (UN), to achieve countries' systemic sustainability. The identification of local techniques that contribute to the different SDG helps to achieve their territorialization and application as public policy. Therefore, this paper presents a literature review, categorizing the studies into different generations based on their main application purpose and presents a linkage of the LID benefits to different SDG. Some challenges were identified requiring further investigation, such as the need to identify and quantify the energy demands for LID practices maintenance and their incorporation in the system final energy balance, identification of processes that contribute to carbon sequestration and emission, and risks of emerging pollutants for human health from water reuse and nutrient cycling for sustainable agriculture.

Environmental change holds many social risks, exposing vulnerable communities and influencing community resilience. Social Impact Assessment (SIA) and Disaster Risk Assessment (DRA) both address social risks and impacts following from social changes induced by developments and disasters, aiming to ensure increased and sustainable community resilience. Although similar in purpose, SIA and DRA are rarely intentionally integrated, and while published research is sparse, it does suggest that their integration is an emerging trend. Therefore, as a step to investigate integration, and acknowledging the importance of theoretical underpinnings, this paper investigates the integration of SIA and DRA for increased community resilience. The investigation reveals three distinct areas of potential integration i.e. focus (people centred for sustainable development), approach (pro-active, multi-stakeholder and transdisciplinary), and regulation (mandated under legislative requirements). These findings suggest that both SIA and DRA can benefit significantly from integration, and thereby contribute to increased resilience and improving the social well-being for communities at risk.

Disruptions in the natural gas supply chain result in reduced throughput and associated emissions and losses, causing significant economic, environmental, and social impacts. Therefore, it is crucial to design supply chains that are resilient and sustainable to prevent or reduce the effects of disruptions. This paper proposes a novel Mixed-Integer Linear Programming model, which optimizes the natural gas supply chain in terms of resilience and sustainability, by examining the impact of an additional workflow design (contingency pipeline) located between the shutdown inlet and outlet nodes in the transmission echelon. The model is applied to a "real world" case, using data collected from gas companies operating in Nigeria. Both steady and transient states of the system are examined in this study through a set of scenarios. The best final solution was found to yield 93.6% performance increase when compared to target throughput and 63% performance increase with the introduction of the contingency when compared with the baseline scenario.
