Climate Resilient Infrastructure

Abstract: Prepared by the Committee on Adaptation to a Changing Climate of ASCE Civil infrastructure systems traditionally have been designed for appropriate functionality, durability, and safety for climate and weather extremes during their full-service lives; however, climate scientists inform us that the extremes of climate and weather have altered from historical values in ways difficult to predict or project. Climate-Resilient Infrastructure: Adaptive Design and Risk Management, MOP 140, provides guidance for and contributes to the developing or enhancing of methods for infrastructure analysis and design in a world in which risk profiles are changing and can be projected with varying degrees of uncertainty requiring a new design philosophy to meet this challenge. The underlying approaches in this manual of practice (MOP) are based on probabilistic methods for quantitative risk analysis, and the design framework provided focuses on identifying and analyzing low-regret, adaptive strategies to make a project more resilient. Beginning with an overview of the driving forces and hazards associated with a changing climate, subsequent chapters in MOP 140 provide observational methods, illustrative examples, and case studies; estimation of extreme events particularly related to precipitation with guidance on monitoring and measuring methods; flood design criteria and the development of project design flood elevations; computational methods of determining flood loads; adaptive design and adaptive risk management in the context of life-cycle engineering and economics; and climate resilience technologies. MOP 140 will be of interest to engineers, researchers, planners, and other stakeholders charged with adaptive design decisions to achieve infrastructure resilience targets while minimizing life-cycle costs in a changing climate

This report discusses ways of enhancing government capacities to prevent, react and rebuild, thereby minimising the impact of natural disasters on infrastructure assets and operations. It identifies data, collaboration and technologies as drivers of resilience, and highlights financial resources, technical skills and regulatory frameworks as key enablers. The report presents seven actionable principles to ensure infrastructure resilience, drawing from global good practices and in-depth analyses of infrastructure projects in Colombia, Ghana, India, Indonesia, Japan, Mozambique and the United States.

Infrastructure—electricity, telecommunications, roads, water, and sanitation—are central to people’s lives. Without it, they cannot make a living, stay healthy, and maintain a good quality of life. Access to basic infrastructure is also a key driver of economic development. This report lays out a framework for understanding infrastructure resilience - the ability of infrastructure systems to function and meet users’ needs during and after a natural hazard. It focuses on four infrastructure systems that are essential to economic activity and people’s well-being: power systems, including the generation, transmission, and distribution of electricity; water and sanitation—especially water utilities; transport systems—multiple modes such as road, rail, waterway, and airports, and multiple scales, including urban transit and rural access; and telecommunications, including telephone and Internet connections.

To best serve current and future generations, infrastructure needs to be resilient to the changing world while using limited resources in a sustainable manner. Research on and funding towards sustainability and resilience are growing rapidly, and significant research is being carried out at a number of institutions and centers worldwide. This handbook brings together current research on sustainable and resilient infrastructure and, in particular, stresses the fundamental nexus between sustainability and resilience. It aims to coalesce work from a large and diverse group of contributors across a wide range of disciplines including engineering, technology and informatics, urban planning, public policy, economics, and finance. Not only does it present a theoretical formulation of sustainability and resilience but it also demonstrates how these ideals can be realized in practice. This work will provide a reference text to students and scholars of a number of disciplines.

This book describes the urgent challenge faced by cities worldwide to become resilient to climate change impacts. This challenge goes further than the ability to resist the impacts of extreme weather conditions. Coping with climate impacts and the ability to recover from them are equally important, as well as the capacity to adapt to the effects of climate change and the ability to transform the entire urban system. The book explores how the resilience journey for coastal cities in particular encompasses using scientific knowledge but also the knowledge of citizens and practitioners. Measures and strategies on different scales are needed, from national scale all the way down to neighbourhood, street level and building level. Representing the holistic nature of climate resilience, this collection contains unique insights from leading scientists and practitioners in areas of expertise such as engineering, social sciences and urban design. It will be a valuable resource for scholars, students, practitioners and policy makers interested in the development of resilient and sustainable urban environments.

To sustain Africa’s growth, and accelerate the eradication of extreme poverty, investment in infrastructure is fundamental. In 2010, the Africa Infrastructure Country Diagnostic found that to enable Africa to fill its infrastructure gap, some US$ 93 billion per year for the next decade will need to be invested. The Program for Infrastructure Development in Africa (PIDA), endorsed in 2012 by the continent’s Heads of State and Government, lays out an ambitious long-term plan for closing Africa’s infrastructure including trough step increases in hydroelectric power generation and water storage capacity. Much of this investment will support the construction of long-lived infrastructure (e.g. dams, power stations, irrigation canals), which may be vulnerable to changes in climatic patterns, the direction and magnitude of which remain significantly uncertain. Enhancing the Climate Resilience of Africa 's Infrastructure evaluates -using for the first time a single consistent methodology and the state-of-the-arte climate scenarios-, the impacts of climate change on hydro-power and irrigation expansion plans in Africa’s main rivers basins (Niger, Senegal, Volta, Congo, Nile, Zambezi, Orange); and outlines an approach to reduce climate risks through suitable adjustments to the planning and design process. The book finds that failure to integrate climate change in the planning and design of power and water infrastructure could entail, in scenarios of drying climate conditions, losses of hydropower revenues between 5% and 60% (depending on the basin); and increases in consumer expenditure for energy up to 3 times the corresponding baseline values. In in wet climate scenarios, business-as-usual infrastructure development could lead to foregone revenues in the range of 15% to 130% of the baseline, to the extent that the larger volume of precipitation is not used to expand the production of hydropower. Despite the large uncertainty on whether drier or wetter conditions will prevail in the future in Africa, the book finds that by modifying existing investment plans to explicitly handle the risk of large climate swings, can cut in half or more the cost that would accrue by building infrastructure on the basis of the climate of the past.

This book aims to cover most subject areas of green infrastructure such as components, multi-functionality, and integration to build environment, contribution to urban sustainability, sustainable and smart city development, urban climate change nexus, green buildings and rating systems, economic assessment, and quantification of green infrastructure. The impending climate crisis, as well as the ongoing COVID-19 pandemic, has highlighted the importance of green infrastructure in and around cities, prompting a call for more functional and sustainable urban planning and design. A number of recent studies have shown that green infrastructure provides a wide range of ecosystem functions and services critical to human well-being and urban sustainability, which is especially important during climatic and health crises. In this book, the authors emphasize the importance of existing green infrastructure in coping with climate change-induced stresses, such as increasing climate variability and extreme temperature and precipitation events, as well as contributing to urban dwellers' physical and mental health. Green infrastructure, in both cases, plays a significant role in providing urban areas with resilience capacity, which is critical to urban sustainability. The authors also emphasize the importance of expanding and improving green infrastructure, particularly in vulnerable areas, through integrative and participatory processes. Appropriate integration of green-gray infrastructure and development of climate resilient cities is the core theme of this publication. Further, it emphasizes sustainable development which has become an imperative requirement to the world to move fore and climate change-built environment nexus, the most critical global crisis. Though several books were published globally on the green infrastructure and urban resilience individually, books are rarely published combining both disciplines. This book identifies and addresses the gap through comprehensively discussing on both interlinked areas which is essential for the sustainable urban development. Further, it explores on urban climate resilience, urban sprawl, urbanization, resilience drivers, essentials of city resilience, policy implications, challenges, and future perspectives. This book is a useful fundamental guide in practical applications of green infrastructure in built environment in sustainability context. Further, it enlightens on the significance of transforming the conventional building construction trend to sustainable urban planning designs and building development, exploring on the strategic pathway on building urban climate resilience while signifying the importance of healthy built environment through discussing on the nexus between climate change and built environment.

MOP 140 provides guidance for developing or enhancing of methods for infrastructure analysis and design to achieve infrastructure resilience targets while minimizing life-cycle costs in a changing climate.
