Protecting nature in Sri Lanka’s capital for resilience and sustainability
In 2014, the island was listed as one of the least urbanized countries in the World Urbanization Prospects (WUP), with less than 20 percent of the population in urban areas. By 2050, WUP projected that number would rise to only 30 percent.
Does this mean we still have to worry about the country’s urbanization? The short answer is yes.
This is, after all, an island nation with one of the highest population densities, complex and evolving social systems and intricate ecosystems.
Meanwhile, urbanization, even at relatively slower pace, is still changing migration patterns, altering the way urban populations consume resources, and impacting the affordability of land and other assets.
These, in turn, are increasing the demand for resources. Growing inequality can be seen as a result of the displacement of less affluent communities, while the loss of important ecosystems has negatively affected resilience and sustainability.

To be honest, I have never really been a fan of motorsport racing, but Formula E is something different. Regular sports car racing has always felt too loud, too polluting and a bit pointless, but electric car racing is changing my perception rapidly. The most recent Formula E race and associated FIA Smart Cities event in Santiago, Chile last week highlighted the importance of sustainable mobility and the advantages of advancing electric technology as quickly as possible. Extremely fast electric cars, whooshing by cheering audiences with a distinctly electric whizzing sound, made me realize that the future is definitely now.
Like many, we were relieved to hear from the Government of Madagascar and WHO in November last year that the pulmonary plague outbreak in Madagascar had been contained. Plague is a disease caused by bacteria called Yersinia pestis that are typically transmitted by rodents through their fleas but can also be transmitted from human to human. Since the onset of the outbreak in early August 2017, there had been 2,300 human cases of plague reported, leading to 207 deaths (WHO update). WHO called for continued vigilance until the end of the plague season at the end of April, as more cases of bubonic plague should be expected and could lead to a resurgence of pulmonary plague. The President of Madagascar also committed to establishing a permanent “plague unit” at the level of the Prime Minister’s office to work on the eradication of plague―rightly so, as experience tells us that addressing risks at the interface of human, animal and environmental health is challenging.
Planning is a theme in cities as ancient as Rome, Cairo, and Athens to as modern as New York and Singapore. It is used as an instrument to manage collective living. Planning remains key in shaping the urban contract of how and to what end people are willing to inhabit the same space.
Madagascar is witnessing rapid urbanization. From an overall population of 24.8 million (2016), the country has close to 7 million urbanites, compared to 2.8 million in 1993. Cities generate about 3/4 of the national GDP, with the capital city, Antananarivo, contributing more than 50%.
The World Bank Group (WBG) is currently implementing a new approach to development finance that will help better support our poverty reduction and shared prosperity goals. This crucial effort, dubbed Maximizing Finance for Development (MFD), seeks to leverage the private sector and optimize the use of scarce public resources to finance development projects in a way that is fiscally, environmentally, and socially sustainable.
There are several reasons why cities and transport planners should pay close attention to the MFD approach. First, while the need for sustainable urban mobility is greater than ever before, the available financing is nowhere near sufficient—and the financing gap only grows wider when you consider the need for climate change adaptation and mitigation. At the same time, worldwide investment commitments in transport projects with private participation have fallen in the last three years and currently stand near a 10-year low. When private investment does go to transport, it tends to be largely concentrated in higher income countries and specific subsectors like ports, airports, and roads. Finally, there is a lot of private money earning low yields and waiting to be invested in good projects. The aspiration is to try to get some of that money invested in sustainable urban mobility.

As we reflect on 2017, the truly devastating impact of climate change is being felt across the globe. The evidence has never been clearer that the impact of climate change is happening now. The World Bank's “Shockwaves” report estimates that, without major investment, climate change will push as many as an additional 100 million people into poverty by 2030.
Landing in Port-au-Prince awakens your senses. Exiting the airplane, you are re-energized by the explosion of colors, the welcoming smiles, and the warm weather – particularly when coming from a cold January in Washington, D.C. Loud honking, a high density of houses and buildings, and streets bustling with pedestrians and small informal businesses are all evidence of the rapid urbanization process in Haiti.
As soon as you land, the challenges of the city are evident; Port-au-Prince expands to the ocean on flat plains exposed to flooding and quickly rises on steep hills with challenging access and risks of landslides and flash floods. The reconstruction efforts after the earthquake in 2010 are still ongoing, and many of the houses seem to be hanging from the sky, perched on steep slopes. If you look at the houses from afar they appear as a single skyscraper, as distance makes the houses seem as if they are built on top of the one another. These false skyscrapers are highly exposed to landslides, flooding and earthquakes.
Kanwar Jheel is the largest in a series of 18 wetlands spread across the Ganges flood plains in India’s north Bihar. For generations, these wetlands have been the mainstay for this densely populated region, enabling families to farm the fertile soil and fish in nutrient-rich waters.
During the monsoon, when the River Burhi Gandak - a Ganges tributary - overflows its banks, the wetlands absorb the runoff, protecting this extremely flood-prone region. When the rains are over, the water shrinks to one tenth the size, exposing marshes and grasslands that create a mosaic of habitats for a wide variety of flora and fauna.
In winter, over 60 species of duck and waterfowl visit these wetlands on their annual migration routes along the Central Asian Flyway.
Sri Lanka and Maldives share much more than the tag of tourism hot spots, beautiful beaches, and similar cultural traits. Both island nations have a range of unique environments that are rich in biodiversity and serve a myriad of ecosystems functions.
Both countries are home to rich wetlands with a variety of fauna and flora that benefit the ecosystem, including flood protection, water purification, and natural air conditioning and provide food and support to local communities.
Sri Lanka has actively been working to ensure these essential ecosystems are protected. The Maldives has too commenced such great work. This work has produced a wealth of knowledge and innovations on how to manage and conserve wetlands.
Managing wetlands in Sri Lanka and Maldives
The wetland management and land use planning effort undertaken in Colombo under the World Bank-financed Metro Colombo Urban Development (MCUDP) project showcases resilience in urban land use planning and highlights how a city can become more livable by intermingling green spaces to its urban fabric. All this, while protecting wetlands and reaping the benefits of their natural ecosystem functions.
The MCUDP used robust strategies and sustainable economic models, such as wetland parks, to help save urban wetlands from threats such as encroachment and clearing. Through the Climate Change Adaptation Project (CCAP), funded by the European Union and the Government of Australia, Maldives has also taken steps to manage threats to its largest wetlands.
While the approaches to wetland management in both countries have been different there are many key lessons that can be shared.
Cities across Nepal—and in the developing world—produce more waste than ever before, due to a spike in population and a surge in new economic activity and urbanization. Properly disposing and managing solid waste has thus become urgent for city municipalities.
As a result, landscapes and public spaces in Nepal’s urban centers are deteriorating. Less than half of the 700,000 tons of waste generated in Nepal’s cities each year is collected. Most waste is dumped without any regulation or oversight and several municipalities do not have a designated disposal site, leading to haphazard disposal of waste—often next to a river—further aggrevating the problem.
With urbanization rising, the costs of inaction are piling up and compromising people’s health and the environment. In most cases, the poor suffer the most from the resulting negative economic, environmental, and human health impacts.
