Just ahead of this year’s anniversary of the Indian Ocean tsunami of 2004, I visited the Tsunami Honganji Vihara site in Sri Lanka where upwards of 2,000 people died when their train was destroyed by the force of the waves. Shortly after my visit, Sri Lanka was faced with an unusually large tropical cyclone that pummeled the capital of Colombo, and caused extensive flooding, power failures and infrastructure damage. And, a few thousand miles away, Bali’s highest volcano, Mount Agung, was threatening to erupt, causing considerable anxiety in Colombo that it could trigger another tsunami event of the same magnitude of the 2004 disaster.
Upon my return to the United States I learned of the raging wildfires in California causing massive damages.
This year’s seemingly never-ending adverse weather events, exacerbated by climate change, along with adverse natural events such as earthquakes, are negatively impacting critical infrastructure globally. Some might describe 2017 as a global “annus horribilis” for adverse “force majeure” events.

The Ganges Basin in South Asia is home to some of the world’s poorest and most vulnerable communities. Annual floods during monsoon season cause widespread human suffering and economic losses. This year, torrential rains and catastrophic floods affected more than 45 million people, including 16 million children. By 2030, with ongoing climate change and socioeconomic development, floods may cost the region as much as $215 billion annually.
Metro Manila -- my current home -- is a metropolis of extraordinary contrast. Referred to as the National Capital Region, it is the workhorse of the country, housing about 12.8% of the total population and producing about 38% of national GDP. Metro Manila is a key contributor to the country’s dynamic and vibrant economy, which has been among the fastest growing in East Asia in recent years. With glittering high rise buildings, a Starbucks on seemingly every corner, and bustling commerce wherever you look, one could be lulled into thinking that the citizens of Metro Manila all have a comfortable life.
As Vietnamese, we look very fondly to Singapore as a model for development in the region, especially fostered by a close relationship between Vietnamese leaders and the former Minister Mentor Lee Kuan Yew—Singapore's founder and mastermind behind all its modern-day achievements. Singapore represents modernity and civilization, notably with limited natural resources. The city-state has proved an applicable model of development for cities in Vietnam to achieve not only competitiveness but also sustainability and inclusiveness.
I just returned to Vietnam after attending the World Bank’s first-ever , a series of events that brought together city leaders from across Asia and beyond to explore innovative approaches to urban planning and management.
A topic that cut across all these areas is flood risk management, which was featured extensively during the launch event of the Global Platform for Sustainable Cities. I had the opportunity to learn more about the role of green mitigation infrastructure in integrated urban flood risk management, with lessons from Japan, Korea, Sri Lanka, Senegal, and the Netherlands. In these countries, green structures such as retarding basins, permeable pavement, and rainwater storage or infiltration trench have complemented conventional structural measures to reduce flood risk in a cost-effective manner.
Singapore: the beautiful city state, famed for its lush gardens, splendid food, culturally diverse communities, and the cocktail Singapore Sling. I was there last week for the World Bank’s 2016 Urban Week. The event brought together leading city officials from all over the world and staff from international organizations. It was an excellent exchange on how to tackle urban planning in a sustainable and integrated way. One lesson that emerged from the gathering is that cities that are resilient to natural disasters are also more economically competitive. Singapore is itself a prime example of a city that has understood the importance of connecting disaster risk management, urban planning, and quality living.
How can water resource agencies make smart investments to ensure long-term water reliability when the future is fraught with deep climate and economic uncertainty? Water resource agencies around the world are grappling with this question at a time of unprecedented water stress, growing demands, uncertain climate change, and limited budgets. We helped SEDAPAL, the water utility serving Lima, Peru, answer this question by drawing on state of the art methods for decision making under deep uncertainty.
Recognizing the urgency of Lima’s water situation, SEDAPAL has developed an aggressive multi-billion dollar Master Plan to implement 14 large and diverse infrastructural investments projects between now and 2040 at a total cost of US$2.7 billion. Together, the investments are designed to meet the 30 percent increase in water demand that SEDAPAL projects for the coming decades.
