Go with the flow – adaptive management for urban flood risk

The future is uncertain. It’s hard to know exactly how our climate will change. That means there is also deep uncertainty around its impacts on flooding, the most prevalent disaster worldwide. Floods account for 43% of all recorded disaster events in the past 20 years. Will climate change exacerbate flooding events? How much will sea level rise? How extreme will rainfall be?

What we do know is that the best way to cope with uncertainty is flexibility.

While it may be difficult to predict impacts, we can – and must – take action. Growing uncertainty means preparation is even more urgent. To meet future challenges, we need adaptable urban flood management today.

Better forecast, better preparedness – investing in improved weather services

Sun or rain? Most of us rely on the daily weather forecast to know what to wear or whether to bring an umbrella. However, for millions of people living in flood prone areas, timely and accurate forecasts, as well as early warning, can impact more than just clothing choices –they can help minimize flooding impacts.
 
Floods are the most frequent and damaging among natural hazards. Between 1980 and 2016, floods led to economic damages exceeding US$1.6 trillion, and more than 225,000 people losing their lives. Compounded by rapid urbanization and climate change, these losses will likely increase, especially in fast-growing countries.

The future of transport is here. Are you ready?

Technology is transforming transport with a speed and scale that are hard to comprehend. The transport systems of tomorrow will be connected, data-driven, shared, on-demand, electric, and highly automated. Ideas are moving swiftly from conception, research and design, testbed to early adoption, and, finally, mass acceptance. And according to projections, the pace of innovation is only going to accelerate.

Autonomous cars are expected to comprise about 25% of the global market by 2040. Flying taxis are already tested in Dubai. Cargo drones will become more economical than motorcycle delivery by 2020. Three Hyperloop systems are expected by 2021. Maglev trains are already operating in Japan, South Korea, and China, and being constructed or planned in Europe, Asia, Australia, and the USA. Blockchain technology has already been used to streamline the procedures for shipping exports, reducing the processing and handling times for key documents, increasing efficiency and reliability,

Communicating volcanic risk: lava, eruptions and uncertainty

We live in an age of compounding uncertainty. The unpredictable impacts of climate change and the rapid urbanization of societies is increasing the complexity, difficulty, and necessity of making sound decisions when faced with numerous options. This uncertainty is acute with respect to natural disasters – for example, predicting hurricane intensity or locating the next big earthquake remain challenging tasks despite advances in science and monitoring tools.
 
The challenge of anticipating and communicating the risk of volcanic eruptions to communities requires complex decision-making. Ecuador’s Cotopaxi Volcano and Indonesia’s Mount Agung are recent examples where the warning signs were present (small earthquakes, increasing gas emissions, and more), yet an eruption came much later than expected. Volcanic eruptions are therefore a double-edged sword that often creates a decision-making dilemma. While signs of volcanic activity can provide adequate time for preparation and evacuation, the very same signs can also create conditions of extreme uncertainty, which can be exacerbated by piecemeal communication around eruption events.
 
So, what have we learned from recent experiences on the challenges of communicating volcanic risk? 

Connecting with the people beyond the computers: my experience in flood risk management in Buenos Aires

After spending several years in front of a computer every day, I began to feel removed from those people who were the real reason for my work, which aims to build a safer, healthier and more prosperous environment. But when people I knew were directly affected by the issues I was working on, my work took on more meaning and urgency.

Mind the gap: How bringing together cities and private investors can close the funding gap for urban resilience

By 2050, two-thirds of all people will live in cities. Each year, 72.8 million more people live in urban areas. That’s the equivalent of a new San Diego appearing every week.
 
But fast growth, and a high concentration of people and assets, makes cities vulnerable to climate change and disasters. By 2030, climate change alone could force up to 77 million urban residents into poverty.

As we celebrate Earth Day 2018 and continue the fight against climate change, cities are striving to become more sustainable, investing in ways to reduce their vulnerability to disasters and climate change. Achieving resilience is the goal – and the good news is that cities aren’t alone on the team.

Top 7 disruptive technologies for cities

Imagine you were working in development and poverty reduction in the early 1990s (I was!). Only one website existed in all the world in August 1991 (today there are over 1.5 billion). Mobile phones were expensive, rare, and clunky. Very few would anticipate a situation in which India would have more mobile phones than toilets.

To paraphrase Bill Gates: we tend to overestimate the changes that will happen in the short term and underestimate those in the long term. Technology is quietly but radically disrupting and transforming how cities deliver services to their citizens. It does that in a way that fundamentally alters not just the mode of delivery but its underlying economics and financing.

Here are the top 7 disruptive technologies revolutionizing service delivery in cities (in no particular order):

Roma inclusion: leveraging opportunities for social change

April 8 was International Romani Day. As we celebrate the Roma people and their culture, we must remember the serious issues they face every day: stigmatization, discrimination, exclusion, and poverty. Join Senior Director for the Social, Urban, Rural and Resilience Global Practice Ede Ijjasz-Vasquez and Senior Social Scientist Nina Bhatt as they discuss these issues.
 
 


 

Sustainable Mobility for All: Bringing the vision to life

Making sustainable transport a reality requires a coordinated strategy that reflects the contributions and various interests of stakeholders around the world.
 
The Sustainable Mobility for All partnership has a critical part to play in kickstarting this process. The initiative is working to raise the profile of sustainable mobility in the global development agenda and unite the international community around a vision of transport that is equitable, efficient, safe, and green.
 
The issue of mobility and sustainability resonates well with countries’ concerns. The recent UN Resolution focusing on the role of transport and transit corridors in sustainable development demonstrates the continuing importance attached to the issue of transport and mobility by national governments around the world.

Boosting access to opportunities by connecting cities

Connected cities use urban infrastructure and transportation networks to boost access to economic opportunities and job creation. In Port-Au-Prince, Haiti, a project recently analyzed the flows of people within the city’s network using cell phone data.  The study identified the most critical links in the urban transportation system that can connect people to jobs and businesses to markets. The project won the World Bank Group’s Fiscal Year 2018 Presidents Award for Excellence for using disruptive technology to collect data.
