We have all come across people whose homes have beautiful and always blooming plants and flowers – people with a so-called “green thumb”.
But did you know that cities too can have a “green thumb”? Singapore is certainly one of those cities.
Also known as the "garden city”, Singapore is set to become a "city in a garden”. The abundance of greenery is a striking feature, with parks, green roofs, street side plants, and trees on every corner.
But greenery is not there just to please the eye and create livable public areas — it also helps mitigate the risk of flooding.
Singapore, like many other densely-populated cities, is at risk of flooding. One way to tackle this is by greening public spaces and encouraging private development to follow the principles of the government’s flagship “ABC” program, which looks to make water “Active, Beautiful and Clean”. Carefully planned and implemented, investments in so-called “green infrastructure” are paying off: they make the city more resilient and more sustainable in the long-term, and also create more spaces for people to meet and interact.
Although Singapore’s dedication to greening public spaces is remarkable, it is not the only city that is getting its hands “dirty” to promote natural ecosystems. The Netherlands has been promoting green approaches in urban planning for many years now, with the innovative redesign of sewer systems, or the creation of multi-functional “water squares” which can hold storm water when rain is heavy while otherwise serving as a social space.
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.
Based on the premise that greener cities are the key to a more sustainable future, the World Bank and the Global Environment Facility launched the new Global Platform for Sustainable Cities (GPSC) earlier this month in Singapore. The new platform will help mobilize funding for urban sustainability programs, while also facilitating knowledge exchange between cities.
Thanks to this innovative approach that closely connects finance to knowledge, the GPSC will be uniquely positioned to make cities the driving force of sustainable development.

I like to think of Singapore as the Pelé of urban design. The city regularly appears in the top ranks of globally livable, connected and competitive cities. Pelé once famously said, "Success is no accident. It is hard work, perseverance, learning, studying, sacrifice, and, most of all, love of what you are doing or learning to do”. There is no doubt that Singapore’s accomplishments have been made possible by the hard work, perseverance and far-sightedness of its policy makers.
A 2013 speech by Peter Ho, Chairman of the Urban Redevelopment Authority, outlines the careful thought, planning and attention to detail behind Singapore’s urban policy, particularly the decisions, influence and foresight of Mr. Lee Kuan Yew over the decades of development. One astonishing success has been the provision of affordable housing and the care with which each neighborhood has been designed, taking care of the smallest details, in order to ensure social cohesion and a sense of community. These details include provisions for hawker centers and high quality public green spaces.

To explore this query, we embarked on a cross-country analysis of cities in West, Central and East Africa, seeking to not only better our understanding of urban fragility, crime, and violence, but also identify critical entry points to curb the challenges we would find. In the report Urban Fragility and Violence in Africa: A Cross-country Analysis, we explored one of the most recently relevant but less explored dimensions of fragility and violence in Africa: urbanization.
The world is urbanizing at staggering, unprecedented rates. By 2014, 54% of the world’s population was residing in urban areas. This number is projected to grow to 66% by 2050. Today’s large cities are concentrated in developing countries, with medium-sized African and Asian cities as the fastest growing urban agglomerations. People migrate fervently to urban areas with hopes of higher per capita incomes, increased employment levels, improved living conditions and well-being, and better chances to integrate into the national territorial economy.
Unfortunately, this promise has yet to be fulfilled in many cities. Often, the urbanization process is poorly managed and the mismatch between the growing number of migrants and the institutional and infrastructural capacity of cities is large. Experts argue that “the pace of urbanization, together with its sheer scale, is likely to stress national and urban institutions in many developing countries to their breaking point."
In other words, cities are expected to "do more with less"... This can only happen if local government practitioners have the right tools and knowledge to manage their resources as strategically and efficiently as possible. To help cities get their financial house in order, the World Bank has developed the Municipal Finances Handbook (available in English and Spanish), which provides government officials with extensive guidance on controlling expenditures, strengthening revenues, mobilizing external funds, achieving creditworthiness, and adopting good borrowing practices.
Lead Urban Specialist Catherine Farvacque-Vitkovic tells us more about the handbook and the associated e-learning course: “Municipal Finances - A Learning Program for Local Governments”.
Please note the next edition of our online course will run from March 30 - May 23, 2016. Click here to learn more and sign up (registration ends March 30).
To discuss some of the key infrastructure challenges faced by its client countries, the World Bank recently hosted its first International Conference on "Sustainable Development through Quality Infrastructure” in Tokyo, Japan. But what exactly do we mean by "quality infrastructure", and what role can it play in creating resilient, sustainable cities?
Pritzker Prize winner Alejandro Aravena’s Elemental firm designed the “half a good house”, which includes gaps between the houses for residents to fill according to their own needs.
The problem is that most cities are not prepared to absorb these numbers. The tragic result is chaos, inequality and environmental damage. One clear manifestation of the mismatch between people’s demand for opportunities to prosper and the inability of cities to maximize the benefits of agglomeration while minimizing the costs of congestion is the omnipresence of slums throughout the world. Today, one billion people live in slums; worse still, many of those settlements are in areas highly vulnerable to natural disasters. By 2030, this figure is expected to double.
To absorb this ever-increasing demand for affordable urban housing, would require creating, in effect, a new city capable of housing 1 million people – every week during the next 15 years. Governments are already overwhelmed. The private solution of reducing the size of dwellings and relocating them to the peripheries of cities has produced economic and social segregation, which has become a ticking bomb for unrest.
During the past 12 years, the Chilean architect, Alejandro Aravena, 48, has offered solutions to the global housing crisis that are so creative, speedy, budget-conscious and scalable that he has been awarded the 2016 Pritzker Prize, considered the Nobel for architecture. His work—and the prize—challenge architects to envision innovative buildings not just for businesses and other wealthy clients but for all the people.
