Resilient Infrastructure Investments Could Save Trillions
By Sunny Lewis
WASHINGTON, DC, June 25, 2019 (Maximpact.com News) – Investing in more resilient infrastructure in low- and middle-income countries would yield a net benefit of US$4.2 trillion, with $4 in benefit for each $1 invested, finds a new report from the World Bank and its Global Facility for Disaster Reduction and Recovery (GFDRR).
GFDRR is a grant-funding mechanism, managed by the World Bank, that supports disaster risk management projects worldwide. Working on the ground with over 400 local, national, regional, and international partners, GFDRR provides knowledge, funding, and technical assistance.
The report, “Lifelines: The Resilient Infrastructure Opportunity,” lays out a framework for understanding infrastructure resilience, that is the ability of infrastructure systems to function and meet users’ needs during and after a natural disaster.
It examines four essential infrastructure systems: power, water and sanitation, transport, and telecommunications. Making them more resilient is critical, the report finds, not only to avoid costly repairs but also to minimize the wide-ranging consequences of natural disasters for the livelihoods and well-being of people.
“Resilient infrastructure is not about roads or bridges or power plants alone. It is about the people, the households and the communities for whom this quality infrastructure is a lifeline to better health, better education and better livelihoods,” said World Bank Group President David Malpass, an American economist who took over the position in April. A Republican, Malpass is a former Under Secretary of the Treasury for International Affairs under President Donald Trump.
“Investing in resilient infrastructure is about unlocking economic opportunities for people. This report offers a pathway for countries to follow for a safer, more secure, inclusive and prosperous future for all,” he said on June 19, upon releasing “Lifelines.”
Using a set of micro-data on about 143,000 firms, the report estimates the monetary costs of infrastructure disruption for firms and households in 137 low- and middle-income countries, representing 78 percent of the world population.
“In this time of rapid climate change and intensifying natural disasters, infrastructure systems are under pressure to deliver resilient and reliable services,” the report states, while finding that the lack of resilient infrastructure harms people and companies more than previously understood.
Natural disasters cause direct damages to power generation and transport infrastructure, costing about US$18 billion a year in low- and middle-income countries. But the wider disruptions that they impose on households and firms is a much bigger problem.
Disruptions caused by natural hazards, as well as poor maintenance and mismanagement of infrastructure, costs households and firms at least US$390 billion a year in low- and middle-income countries, the authors calculate.
“It is cheaper and easier to build resilience if we look beyond individual assets, like bridges or electric poles, and understand the vulnerabilities of systems and users,” said Stephane Hallegatte, a lead economist with the GFDRR at the World Bank and lead author of the report. “By doing so, entire systems can be better designed and with greater flexibility so that damages are localized and do not spread through entire networks, crippling economies at large.”
Today Africa and South Asia bear the highest losses from unreliable infrastructure.
In Kampala, Uganda, even moderate floods block enough streets to make it impossible for over a third of Kampalans to reach a hospital during the critical window of time following a medical emergency.
Tanzanian firms are incurring losses of US$668 million a year (or 1.8 percent of GDP) from power and water outages and transport disruptions, regardless of their origin. Almost half of transport disruptions in the country are also due to floods, and flood-related transport disruptions cost more than US$100 million per year.
Reliable access to electricity has more favorable effects on income and social outcomes than access alone in Bangladesh, India, and Pakistan, boosting per capita income, study time for girls and women’s participation in the labor force.
In India, access to electricity increases women’s employment by 12 percent, but access is usually unreliable. Where access is reliable and available 24/7, the increase reaches 31 percent.
East Asia is a hotspot of infrastructure asset vulnerability to natural hazards and climate change. There are four East Asia countries among the top five countries globally in terms of risk to transport assets, and three out of five for the risk to power generation.
In China, 64 million people are dependent on waste water treatment plants that are exposed to earthquake and soil liquefaction risks, and almost 200 million people are dependent on treatment plants that will be exposed to increasing flood risks due to climate change.
In Peru, landslides often interrupt road traffic, causing large losses for users. Increasing the redundancy of the road network can be more efficient than trying to make roads resistant to landslides. This is especially the case around Carretera Central, Peru’s National Rute 22, a strategic export route for agricultural products, that is subject to heavy rains and frequent landslides from December through March.
The additional up-front cost of more resilient infrastructure ranges from negative to a doubling of the construction cost, depending on the asset and the hazard, the report finds. Interventions to make assets more resilient include using alternative materials, digging deeper foundations, elevating assets, building flood protection around the asset, or adding redundant components.
But the report also states that, “Finally, sometimes the best way to make an infrastructure resilient is not to build it.”
Citing the 2019 study “Global investment costs for coastal defense through the 21st century,” by Robert J. Nicholls and his team, the World Bank report warns that coastal protection against storm surges and a rise in sea level would make economic sense only for about 22–32 percent of the world’s coastlines through the 21st century.
“Thus, some communities may have to retreat gradually or use lower-cost or nature-based approaches to coastal defense,” the World Bank states. “These communities are mostly in low-density areas where the costs of protection are too high to be affordable. In those areas, the best approach to resilience may be not to build new infrastructure. This approach, however, has to be complemented by a consistent strategy to manage retreat, while maintaining livelihoods and community ties.”
The report offers five recommendations to ensure that infrastructure systems and users become more resilient:
- Get basics right. Tackling poor management and governance of infrastructure systems is key. For instance, a poorly-maintained infrastructure asset cannot be resilient.
- Build institutions for resilience. Wider political economy challenges also need to be addressed, and critical infrastructure assets and systems need to be identified so that resources can be directed toward them.
- Include resilience in regulations and incentives. Financial incentives can be used to ensure that the full social cost of infrastructure disruptions are accounted for, encouraging service providers to go beyond just meeting mandatory standards.
- Improve decision making. Access to better data, tools, and skills could be a game changer in building resilience: for instance, digital elevation models for urban areas are not expensive and are critical to inform hundreds of billions of dollars in investments per year.
- Provide financing. The right kind of financing at the right time is key. For instance, small amounts of resources can support regulators and be used at the early stages of infrastructure design compared to the billions needed to repair and recover in the aftermath of a disaster.
“For infrastructure investors – whether governments, development banks or the private sector – it is clear that investing in resilient infrastructure is both sound and profitable,” said John Roome, senior director, Climate Change, World Bank. “It is not about spending more, but about spending better.”
The report was made possible with the financial support of the Japan-World Bank Program for Mainstreaming Disaster Risk Management in Developing Countries .
