The Cascading Benefits of Closing the Urban Services Divide

Closing the urban services divide avoids economic costs, improves quality of life, and can trigger citywide transformative change with the right enabling conditions. Seven case studies from the global South demonstrate how cascading benefits can occur when cities extend infrastructure and services to the excluded. They provide valuable real-world lessons that other cities can learn from.

4.1 Avoided Economic Costs from Closing the Urban Services Divide

The consequences of unplanned, unequal, unsustainable urban development stretch in so many directions that they are difficult to measure. They permeate every aspect of life. As detailed above, they include sprawl, congestion, wasted resources, pollution, deepening poverty, hobbled productivity, danger, disease, and accelerating, potentially catastrophic climate change. Closing or bridging the urban services divide can avoid these costs. It can also yield large dividends across sectors and institutions and improve life for a broad swath of the urban population.171 Steps taken compound and build upon one another, with the whole process yielding more than the sum of its parts. These dividends can multiply from avoided economic costs, to quality-of-life benefits, and even to the potential for citywide transformative change (see Figure 11).

Many wider social and economic costs of the urban services divide mount over time because private markets and actions do not typically account for them. Private actors cannot recognize (or immediately monetize) the benefits that would flow from public investments to narrow the divide and make cities more equitable and sustainable. This is true even when investments in services and infrastructure can clearly pay for themselves many times over. One example is the economic case for extending sewer service to new neighborhoods. Doing this will create customers who will pay for the service. But it also delivers larger, more diffuse economic benefits by sparing people from being sickened by contaminated water.172 Healthier residents need less medical care and are more productive. These types of payoffs can cascade and multiply in the long term in ways that are hard even to predict or calculate. That makes them risky and hard to justify to shareholders of companies looking for revenues and short-term profits. But research shows that the payoff is huge.173

In Sub-Saharan Africa, for instance, low-income households spend about one-third of their income on treating water-related illnesses. Globally, the lack of safely managed sanitation imposes $223 billion a year in health costs, lost productivity, and wages.174 The scale of this challenge is clear when we consider that slums in cities such as Nairobi may have one toilet for every 500 people.175 Each dollar invested in water and sanitation generates between $4 and $34 in benefits by saving time, improving health, and raising productivity.176 Without water-related illnesses hampering people’s productivity, hurting livelihoods, and slowing economic growth (see Box 8), more households would be able to thrive.177

Waterborne diseases are just one example of the costs of current patterns of urban development. Here are some more:

  • Traffic congestion costs up to 10 percent of GDP for large cities such as Beijing, China, and São Paulo, Brazil.178
  • Road accidents consume 5 percent of GDP across low- and middle-income countries.179
  • Power outages lead to lost sales totaling $82 billion per year and additional coping costs of $65 billion per year for backup generators in developing countries.180
  • Water shortages cause urgent and expensive citywide crises. In Jakarta, Indonesia, residents who lacked piped, potable water resorted to digging and extracting too much water from unregulated wells; as a result, the entire city is now sinking as it battles sea level rise and coastal flooding. The city has calculated that it may need to spend over $40 billion on a sea wall around Jakarta Bay.181
  • A study conducted for India estimates that sprawled, disconnected, and poorly planned urbanization could cost between $330 billion and $1.8 trillion per year by 2050. That is equivalent to between 1.2 and 6.3 percent of the country’s GDP. India’s urban population is projected to nearly double to 800 million by then.182 This means that by midcentury, better, smarter urban development could yield economic benefits worth up to more than 6 percent of India’s entire GDP.183

The fact that so much economic activity takes place without adequate infrastructure, government oversight, or support takes a toll across the cities of the global South as well. Informal workers account for 50 to 80 percent of urban employment and generate from 25 to 50 percent of the (nonagricultural) GDP of the global South.184 Yet home-based workers living in informal settlements, street vendors, transport operators, waste pickers, and other informal workers are largely excluded, not just from public infrastructure and services but also often from public spaces and public procurement contracts. This severely constrains their productivity. Power outages, water shortages, and unreliable infrastructure are bad for business. So is being harassed, fined, physically assaulted, or evicted from public spaces, as often happens. This, in turn, constrains output and earnings and makes the supply of goods and services less accessible, reliable, and affordable for everyone.

Box 8 | Flooding causes sanitation, health, and financial challenges for Bengaluru’s under-served neighborhoods

Many residents on the outskirts of Bengaluru, India, live in fear of the rainy season floods devastating their homes. Thulsimma, a 65-year-old woman whose family lives in a suburb of northwest Bengaluru, says, “Sometimes we cannot even sleep at night. We have to be very alert. . . . We protect whatever household items we can, but we can’t remove everything when the rains suddenly come.”

Because many low-income communities like Thulsimma’s develop rapidly, often in low-lying, flood-prone areas, cities often fail to move quickly enough to provide adequate basic services such as water, electricity, sewer networks, and solid waste management, as well as the infrastructure needed to protect homes from natural disasters such as floods. Each year, Thulsimma and her family spend one to three months of their combined income repairing household flood damage. When the rains are very heavy, water backflow from nearby sewers inundates the rajakluve—a central drain connecting the neighborhood network of waterbodies and tanks. Pipes often get blocked by garbage and solid waste dumped into the drain, forcing residents to clean the drain themselves two to three times each year.

Bengaluru has invested more in piped water systems for peripheral neighborhoods in recent years, but the piped water supply is available only for four hours every other day and is stored in large drums. If this supply runs out, Thulsimma recruits help from her sons or neighbors to fetch water from the bore well at the top of a flight of stairs. This water is often “blackish, muddy, and has small worms and larvae in it,” she says. As a result, Thulsimma’s family prefers to buy bottled mineral water rather than using Tata Swach water filters, which must be replaced for US$7 to $9 every two months.

4.2 Better Quality of Life for Households with Citywide Benefits

Bridging the urban services divide will improve the quality of life in poor neighborhoods but can also improve prosperity, health, and well-being across whole cities. Inadequate sanitation harms even those who live in areas with better service. It can pollute drinking water, contaminate food, and unleash disease-spreading flies. Better sanitation also lifts productivity and incomes.185

Well-located, affordable housing near employment opportunities mitigates congestion, traffic hazards, and air pollution; benefits business; and helps attract investment and economic development. It also alleviates the pressure to locate housing on high-risk, environmentally fragile land. Makeshift housing precariously situated on hillsides or on or near dump sites regularly leads to landslide tragedies.

Improving transport for under-served populations also improves safety, reduces commute times, improves livelihoods, and protects the environment.186 Low-income commuters can save upwards of 25 percent of their income with shorter commutes or more affordable options, and this does not account for lost wages due to time spent in long commutes.187 Better transit options would save time and resources that are drained as millions of residents of sprawling cities sit in idling cars in ever-growing traffic jams. It could prevent disabilities and lives lost to traffic accidents, and it would reduce emissions from a growing vehicle fleet.

Figure 12 shows the difference across countries in the share of income spent on commuting by public transport from the periphery to the city center. Data are drawn from a sample of 200 cities and illustrate how residents in poor cities such as Dhaka, Bangladesh, spend an average of 29 percent of the median per capita income. In rich cities such as Singapore, commuters spend an average of only 3 percent of the median per capita income.188

Figure 12 | Residents of low-income cities spend high shares of their income on commuting

Notes: Data are from a 200-city global sample with 192 cities reporting values. The data refer to trips from random points at the periphery of a city to the city center (or the central business district, based on the location of the city hall). We assume 60 trips per month on public transport and 7 round trips per week, which is the typical movement of the working poor (Carruthers et al., 2005). Average daily expenditure, expressed as a percentage of the median per capita income, is 10 percent. Beijing is at the average value, Dhaka’s commuting costs are significantly higher, and Singapore has one of the lowest shares of income devoted to commuting. Compared to other developed cities, such as Hong Kong, London, and New York City, the average bus fare (S$0.63) and train fare (S$0.86) in Singapore are much lower on a nominal basis. The findings remain consistent after the average fares are adjusted using the purchasing power parity of the cities.

Improving access to clean energy has far-reaching benefits as well. Fewer power outages mean less disruption of work, leading to higher incomes and output in both formal and especially informal firms. Electricity consumption per capita is positively correlated with a city’s per capita GDP.189 Household air pollution from inefficient cooking practices and use of solid fuels causes nearly 4 million premature deaths worldwide every year.190 Cleaner cooking could dramatically reduce indoor air pollution from fires burning coal, kerosene, wood, and other organic matter. These are a leading cause of lung and heart disease among women and children; close to half of deaths due to pneumonia among young children are caused by household air pollution. In low- and middle-income countries, WHO has found that 98 percent of cities with more than 100,000 inhabitants do not meet WHO’s air quality guidelines.191 

4.3 The Potential for Citywide Transformative Change

Initiatives that help bring core urban services to under-served groups can set processes in motion that can achieve transformative change—change that is durable, affects many sectors and institutions, improves life for a large swath of the population, and improves economic and environmental outcomes citywide (see Figure 13). We define transformative change as follows:

Change that enhances quality of life for a large segment of the population, affects multiple sectors and institutional practices, continues across political administrations, and is sustained for more than 10 years.192

Focusing on unmet needs in marginalized communities can build the momentum, coalitions, and mechanisms that make broad, durable, transformative change possible and put cities on the path to greater prosperity, sustainability, health, and well-being.

This approach has been adopted in cities around the world. In Colombia, for example, the city of Medellín began improving transport options for isolated hillside communities by building a cable car system. This helped create a coalition of political and private sector leaders interested in citywide change, fueling momentum in other sectors. It led to new schools, new public spaces, and changes to housing policy that legalized informal homes.

However, achieving transformative change is difficult. A city typically needs a strong coalition of leaders and advocates who share a vision and a long-term political commitment and also have the resources needed to take on an urgent problem and implement ambitious reforms. Setbacks and course corrections are common, and each city’s path is unique, but we find that cities can learn from one another’s successes and failures to help usher in their own transformations.

4.4 Diving Deeper into How Transformative Change Occurs

This synthesis report draws on case studies and patterns that emerged from the Towards a More Equal City body of work. The authors distilled lessons from the long-term experiences of seven cities that initiated change in one or more sectors to ensure more equitable access (see Figure 14). Below are summaries and key lessons learned from each:

Figure 14 | A snapshot of Towards a More Equal City case studies—documenting how improving access to services for the under-served created pathways for citywide transformative change

Voices: Rebecca Abers on participatory budgeting in Porto Alegre


  • Ahmedabad, India, introduced the Town Planning Scheme (TPS) to secure urban land for public purposes—specifically to provide services. The program succeeded in negotiating noncoercive land transfers from private landholders for public use. The city was able to obtain land for low-income housing, open spaces, streets, and utilities. The TPS enabled the city to avoid the haphazard, under-serviced expansion that characterizes so many other Indian cities. The program led to the construction of thousands of social housing units and the expansion of a well-planned road network that connects to India’s largest bus rapid transit (BRT) system. The TPS is credited with increasing street density, reducing average trip lengths, and easing road congestion. It was also notable in the way that it accommodated informal settlements in the planning process.
  • In Guadalajara, Mexico, the municipal government established Via RecreActiva, a ciclovía (bike path) connecting different parts of the city. In four of the metropolitan area’s nine municipalities, more than 60 kilometers of major streets are closed to motor vehicle traffic every Sunday. Cyclists and pedestrians reclaim roads normally dominated by cars, making them broadly accessible as a public space. The idea came from a coalition of activists and civil society groups. They advocated for Via RecreActiva, and then they expanded their demands to include access to core infrastructure and services with reforms to allow more public participation in decision-making. The Via RecreActiva transformed the way public space is viewed and used in the city and made governance more inclusive. Though it has not reversed systematic inequality, it marked an important move towards prioritizing people over cars in Guadalajara, a trend that cities around the world are embracing.
  • In Johannesburg, South Africa, in 2013, the city launched the Corridors of Freedom (COF), an effort to overcome the historic spatial inequality dating back to the apartheid period. COF sought to extend public transport networks to under-served areas and create transit-oriented development along these corridors, including affordable housing for the lower middle classes. The ultimate aim was to link these neighborhoods to better employment opportunities. The city expanded its BRT network to these areas, and the private sector is slowly starting to respond with new, affordable housing along these corridors. This effort was also notable for its success in aligning policy from the national to the local level.
  • Kampala, Uganda, is a story of institutional reform and heroic efforts to increase sanitation service in a rapidly urbanizing environment, where the financial resources and local capacity to expand sewer service were nonexistent. The Kampala Capital City Authority and the National Water and Sewage Corporation overcame their historical differences and worked together. They reformed the institutional culture to adopt pro-poor policies, encourage innovation, and improve service delivery. These improvements grew partly out of the city’s partnerships with nonprofits, community groups, and small business and partly out of its support for flexible, innovative approaches to delivering sanitation services. Between 2003 and 2015, the national utility expanded its sewer network only modestly but increased the amount of human waste it was treating more than 30-fold.
  • Porto Alegre, Brazil, introduced participatory municipal budgeting and sustained this approach for nearly 30 years. The initiative built on the popularity of the workers’ political party, which first gained political prominence at the municipal level, and later came to national power. Participatory budgeting was remarkable for its use of deliberative democracy principles at the local level to allocate municipal financial resources and for its annual reports on expenditures to strengthen accountability. Under-served communities would identify their urgent needs and propose these priorities for municipal funding. Participatory budgeting mobilized poor communities, improved access to small-scale infrastructure and services, and ultimately redefined what it means to be an urban citizen. This approach to budgeting became a model replicated around the world.
  • The transformation in Pune, India, was built upon two sectors: public transport and solid waste management. It was led by a diverse coalition of civil society actors, supported by “open-minded” municipal officials, who were able to leverage supportive national policies. The sustainable transport efforts included India’s first BRT system and pro-pedestrian street design. Progress in the area of solid waste management centered around creatively integrating informal waste pickers into the city’s solid waste management system. This enabled the city to provide door-to-door garbage collection and to segregate, process, and recycle waste. It also launched India’s first fully self-owned waste pickers cooperative.
  • In Surabaya, Indonesia, urban transformation grew out of a progressive vision and approach towards the kampung, a local term for informal settlers, the urban poor, and self-built housing and communities. The Surabaya approach represents transformative change because it defies the conventional approach that some governments have taken—that is, to make cities “slum free” by destroying informal settlements and forcibly relocating their residents to the peripheral areas. The approach is participatory and incremental, and it has been sustained over decades. It has allowed poor city dwellers to live in affordable, well-situated housing; preserved a traditional Indonesian urban form; and stabilized the livelihoods and social networks that underpin these communities.

We selected cities from different regions of the global South that had begun transformative interventions in different sectors to close the urban services divide, consulting with experts and practitioners to understand how they did it.193 We looked at the opportunities they seized and the constraints they faced in delivering core services more equitably, the roles played by key actors, and the factors that triggered, enabled, and inhibited change over time. We found that transformative change is neither an outcome nor an end state. Instead, it is a dynamic process that requires a constant, sustained, collective effort. It requires the continuous commitment of political leaders working together with coalitions of diverse stakeholders.

When analyzing strategies and conditions that enable transformative change, key patterns emerge. They include effective governance, access to financing, land management, better data, policies inclusive of informality, coordination, and a shared vision (see Table 1, which maps the cases studies to several key issues, a step towards arriving at the transformations presented below).

Governance—in different ways—plays a central role in every single case. This includes changes in laws and administrative procedures, strong leadership that forges a powerful vision and facilitates coalitions, and alignment between and across different levels of government.

Access to finance is another common theme, with enablers ranging from improved (and wiser use of) access to increased finance, well-structured subsidies, and innovative combinations of instruments.

In several cases, land management—with the right data on land records—was crucial to shaping spatial patterns of development to minimize sprawl and incursion into sensitive environmental areas or vital farmlands while ensuring services as the city expands.

Informality emerges as something to be embraced, although not glamorized. Informally provided services should be seen as a vital part of the city; they provide key services to areas under-serviced by formal systems until improved citywide infrastructure systems can reach them. Policies that support informality can sustain livelihoods, encourage innovative approaches, and support much-needed services.

But even when cities do practically everything right, transformative change can be stalled, thrown into reverse, even derailed by forces beyond its control. A major threat to progress is a change in political leadership. New administrations often like to change course or rebrand policies to claim credit for them. In Johannesburg, Porto Alegre, and Pune, subsequent political leaders turned away from the visions and programs that had held out the promise of transformative change. For example, progress on Johannesburg’s transit-oriented development corridors stalled, with investments delayed or canceled, when new political leaders decided to modify and rebrand it. Participatory budgeting (PB) in Porto Alegre suffered a similar fate. It arose when the Workers Party won power and was designed to align with the party’s democratic socialist ideas. It lasted for almost three decades but, over time, national funding for PB waned and political change at both national and local levels led to its suspension in 2018, with less progressive and inclusive fiscal priorities. Coordination can be a challenge, too, especially when a large portion of the funding for major urban infrastructure projects comes from a patchwork of external grants and donor agencies without a longer-term, citywide plan, as seen in Kampala, Uganda, and Pune.194

4.5 From Vicious to Virtuous Cycles

So far, this report has explained the urgent problems gripping fast-growing cities in low- and middle-income countries around the world, why these trends are accelerating, and why they must be tackled now. It has demonstrated how deepening poverty and inequality, stunted economic development, environmental degradation, and a worsening quality of life directly link to gaping inequities in access to core urban services, such as good-quality housing, water, sanitation, transport, and energy. These burdens weigh most heavily on the poor and excluded, but they harm everyone. Although closing this services gap is difficult, it can generate a multitude of benefits and broader outcomes that help cities meet the SDGs and goals of the Paris Agreement.

Part I of this synthesis report highlighted the daunting challenges in today’s growing cities of the global South, and Part II proposed a new approach for transformative change—an approach centered on closing the urban services divide and harnessing the cascading benefits from doing so. Change is possible, and many cities around the world are already innovating, as the next part of this report will demonstrate. Our unique focus on the services gap in cities offers both an explanation for many of their troubles and a way to escape them. The seven case studies our research analyzed demonstrate how cities can make progress in extending infrastructure and services to populations that have been excluded. They show how, under the right conditions, this can snowball. The knowledge, hope, coalitions, mechanisms, and political momentum marshalled to tackle inequality in one sector can unleash positive change on other fronts. With nations around the world focusing on economic recovery after the pandemic, the next part of this report focuses on an action agenda that can be embraced to emerge from this crisis stronger and build resilience to future crises.

Part III of this synthesis report delves more deeply into how cities can create the conditions necessary to bend their trajectories. These “transformations” build on the key patterns that emerged from our case studies. Evidence shows that prioritizing these transformations can arrest vicious cycles and begin virtuous ones, begin to solve what have been intractable problems, and open up a path to a more humane, just, prosperous, and sustainable future.
