An Introduction to Shared Sanitation

How many people can share a toilet? This question might sound like the start of a joke but it’s actually a serious issue for many across the world. That’s because an estimated 20 percent of the global population do not have their own toilets.
 
In urban areas, almost one person in ten uses a shared household toilet, i.e., a toilet shared with at least one neighboring household. But sometimes no one in the neighborhood owns a private toilet, so some of these families instead have no choice but to use community toilets - that are locally available and used by anyone who lives nearby. In such cases, hundreds of people might be using the same block of community toilets. Now let’s think about the other toilets we all use – when we’re out shopping or running errands, when we’re at work or school, or when we’re in transit. These public toilets might be used by hundreds or thousands of different people at different times of day.
 
Many of us go through the day without giving much thought to this. But for hundreds of millions of people worldwide who do not own their own toilet, these are daily realities. Additionally, even for households who have their own toilet, when they are outside of the home, they still need access to improved sanitation facilities. The illustration below depicts a day in the life of the Mijini family (Mijini means urban in Swahili). The Mijini ’s sanitation situation is great in their home, as they have an individual household toilet, but it’s underwhelming and even dangerous once they leave home for their day. Their experience is not unique, particularly in low- and middle-income countries.

Building bridges: cities helping cities achieve more – a Romanian-Japanese partnership

When U.S. Commodore Matthew Perry arrived in Yokohama in 1854, it was a backwater village in Japan with a largely rural, relatively undeveloped economy. But it soon grew to an urban agglomeration with around 3.7 million people. Since then, Yokohama has managed to continuously reinvent itself – from a port city, to a large industrial area, and now to a modern, global service and lifestyle hub.
 
Within a century, Japan would become the world’s second largest economy. Its growth has been fueled by cities such as Tokyo, Yokohama, Osaka, and Kobe. Japanese cities can offer a myriad of lessons to their counterparts in developing countries.
 
Japanese cities are also at the forefront of dealing with some of the world’s most pressing challenges. For example, cities like Osaka and Toyama have developed a number of tools to address the social issues caused by rapid aging. Most developed and developing cities in the world will face similar challenges in the years to come. Providing a platform where these cities can learn from the experience of Japanese cities may lead to significant development impact.
 
Supported by a partnership between the World Bank and Japan, the Tokyo Development Learning Center (TDLC) does just that.

Understanding Niamey’s flood risk through open source mapping, drones, and modeling

For thousands of years, the Niger River has been the lifeblood for not only Niger, but also its neighboring countries in the Niger River Basin. Yet, even as many Nigeriens depend on the mighty waterway for food, water, and livelihoods, the Niger River also poses a severe flood risk to the West African country during the rainy season. In the third quarter of 2017, widespread flooding due to heavy rains claimed the lives of over 50 people and displaced nearly 200,000.

An engineering design manual is an unlikely device to set pulses racing and even less likely to grab headlines. Yet within the pages of such a newly-released manual, there are vital solutions for one of the most important sanitation challenges which most people have never heard of. 

Alongside the Global Water Security & Sanitation Partnership (GWSP) and the Bill & Melinda Gates Foundation, the World Bank’s Citywide Inclusive Sanitation team has worked with globally-renowned expert Kevin Tayler to produce the newly-published book ‘Faecal Sludge and Septage Treatment - A guide for low and middle income countries.’ For those not familiar with the sanitation sector, this subject may not sound particularly exhilarating but, trust us on this, it’s a crucial issue and the book is a game changer. Here’s why.

Why strengthening land rights strengthens development

Today, only 30% of the world’s population has legally registered rights to their land and home, with the poor and politically marginalized especially likely to suffer from insecure land tenure. Unless this changes, the 2015 United Nations Sustainable Development Goals will be impossible to achieve.

For most of the world’s poor and vulnerable people, secure property rights, including land tenure, are a rarely accessible luxury. Unless this changes, the Sustainable Development Goals (SDGs) will be impossible to achieve.

Land tenure determines who can use land, for how long, and under what conditions. Tenure arrangements may be based both on official laws and policies, and on informal customs. If those arrangements are secure, users of land have an incentive not just to implement best practices for their use of it (paying attention to, say, environmental impacts), but also to invest more.

Three ways governments can create the conditions for successful PPPs

A healthy Public-Private Partnership (PPP) has several defining features: strong competition, bankability with low financial costs, lower risk of renegotiations, secure value for money, and efficiency gains.

What does it take for countries to develop PPPs that can fit this description? Why is it that some countries such as India, Colombia, Turkey, and Egypt have been able to develop strong and successful PPP programs while others have not been able to award any projects under special-purpose PPP legislations? 

Our experience with infrastructure PPPs across the globe suggests that three institutional pillars are needed to increase the probability of PPP success.

Toward Great Dhaka: Seize the golden opportunity

Originally Appeared on the Daily Star

Had you looked across Shanghai's Huangpu River from west to east in the 1980s, you would mostly have seen farmland dotted with a few scattered buildings. At the time, it was unimaginable that East Shanghai, or Pudong, would one day become a global financial centre; that its futuristic skyline, sleek expressways, and rapid trains would one day be showcased in blockbusters like James Bond and Mission Impossible movies! It was also unimaginable that the Shanghainese would consider living in Pudong.

How wrong that would have been! Pudong is now hosting some of the world's most productive companies, and boosting some of the city's most desirable neighbourhoods. And Shanghai has become China's most important global city, lifting the entire hinterland with it.

The same potential for urban transformation exists in Bangladesh, across the Pragati Sarani Airport Road that divides Dhaka into its west and east. West Dhaka is urban, hosting vibrant centres. East Dhaka remains largely rural, with a vast expanse of farmland. This sharp contrast presents a golden urban development opportunity for Dhaka, one that is not available to other major Asian cities.

Realizing the Promise of a Great Dhaka


Dhaka's population has grown from three million in 1980 to 18 million today and it continues to increase rapidly, which is a clear sign of success. However, Dhaka's development has been mostly spontaneous, with its urban infrastructure not keeping pace with its population growth.

Why cultural heritage matters for urban resilience

Barbara Minguez Garcia's picture

Across the disaster risk management community, there is growing recognition that protecting cultural heritage is fundamental to urban resilience. Traditional knowledge embedded in cultural heritage, such as historical evacuation routes or shelters, can help societies cope with natural hazards. Moreover, when these hazards disrupt cultural heritage sites, such as museums, monuments and places of worship, they often cause irreparable damage to people’s cultures, identities and livelihoods.

A case in point is last year’s devastating earthquake in central Mexico, which damaged over 1,500 historic buildings, including the 250-year-old Church of Santa Prisca, one of the country’s grandest and most beloved churches. Mexico is one of a number of countries that have undertaken major efforts to protect cultural heritage sites, including through its Plan Verde, which works to reduce seismic and other disaster risks in Mexico City’s historic center.

On the sidelines of the 2018 Understanding Risk Forum, which was aptly held in Mexico City, Giovanni Boccardi, Chief of the Emergency Preparedness and Response Unit for the Culture Sector of UNESCO, made the case that much more needs to be done to put cultural heritage front and center in the disaster risk management agenda.

30 years of working together to solve Shanghai’s most pressing water problems

Editor's Note: 
The global water crisis is a crisis of too much, too polluted and too little. At the World Bank, our job is to find and implement solutions to tackle this crisis. In the “Water Solutions” blog series, you’ll read about World Bank-supported projects in different countries which demonstrated solutions to the world’s most pressing water issues, to fulfill our vision for a water-secure world.

Cities are growing at a staggering rate, changing our world beyond recognition. For the first time in history, over half the population -- 55 percent -- lives in urban areas.  By 2050, that number will rise to 68 percent.  This rapid urban growth has given rise to sprawling megacities, many of which are in Asia and Africa.

Perhaps no place epitomizes this trend better than Shanghai. In 1990, the city was still primarily an industrial hub with a population of 13 million. By 2016, the figure had ballooned to 24 million, making Shanghai one of the largest metropolitan areas in the world and the financial and economic hub of China.

Highway BR-163 cuts a rough path through Brazil’s conflicting ambitions: to transform itself into an economic powerhouse and to preserve the Amazon as a bulwark against climate change. This beautifully presented story takes you along the 2,000-kilometer BR-163 corridor in Brazil’s Amazon region to look at the competing needs of those living along this important national artery. It’s not just about a road, but about development itself, and why balancing the economic and social needs of a nation and its people is no simple task.
