Rapid urbanization has provided most cities in the world with opportunities to provide more sustainable, vibrant, and prosperous centers for their citizens. But they must first address challenges such as inadequate infrastructure investments, pollution and congestion, and poor urban planning, according to a new report released today. 

The report, Creating Livable Cities: Regional Perspectives, looks at urbanization trends across emerging and developing economies in Africa; Asia and the Pacific; emerging Europe, Central Asia, and the Southern and Eastern Mediterranean; and Latin America and the Caribbean. It is a joint publication by four regional development banks (RDBs) operating in these regions—African Development Bank (AfDB), Asian Development Bank (ADB), European Bank for Reconstruction and Development (EBRD), and Inter-American Development Bank (IDB).

“Cities offer access to key infrastructure, institutions, and services for a good quality of life,” ADB President Mr. Takehiko Nakao said. “They can be centers of innovation for a more livable future for all. But realizing that potential requires forward thinking and flexible planning, adequate capacity at the municipal level, and good governance.”

Mr. Nakao took part in a launch event at the IDB headquarters today in Washington, D.C., with the presidents of the other three development banks: Mr. Akinwumi Adesina of AfDB, Mr. Suma Chakrabarti of EBRD, and Mr. Luis Alberto Moreno of IDB.

The world’s urban population has grown from just 750 million in 1950 (or 31% of the total population) to 4.2 billion in 2018 (55% of the total population)—a number that is estimated to reach 5.2 billion in 2030 (60% of the total population). While the majority of leading economic hubs are still in advanced economies, the center of economic activity is moving toward the developing and emerging markets, the report says. Asia and Africa will account for 90% of urban population growth between 2018 and 2050, with more than a third of this growth to happen in just three countries—the People’s Republic of China (PRC), India, and Nigeria.

Although large and still dominant, megacities of more than 10 million people and national capitals are not the fastest-growing urban areas. Urban areas with fewer than 1 million residents account for 59% of the world’s urban population and are experiencing a faster growth rate across the regions, the report says. 

Cities need large scale investments to develop and maintain infrastructure and services such as urban transport, water supply, sanitation, and solid waste management. In the face of rapid growth, overstretched services, skills shortages, and increased vulnerabilities to disasters are adding to cities’ environmental stress.

The publication examines the types of policy interventions and approaches needed to promote competitive, inclusive, equitable, and environmentally sustainable and climate-resilient cities—four factors that taken together make cities “livable.”

“RDBs play an important role in identifying, distilling, and diffusing knowledge and actions that can accelerate progress toward creating more livable cities,” the report says. Making cities more livable is one of the seven operational priorities of ADB’s Strategy 2030. ADB’s Livable Cities approach puts people and communities at the center of urban development, and promotes strengthening urban institutions through holistic and participatory urban planning and sustainable financing, and use of data and digital technologies to improve urban services to the residents.

As urbanization grows, cities unveil sustainable development solutions on World Day

Newsroom

Over half of the world’s population now live in cities, with numbers expected to double by 2050, but while urbanization poses serious challenges, cities can also be powerhouses for sustainable development; something the UN is spotlighting on World Cities Day, marked 31 October. 

The UN Educational, Scientific and Cultural Organisation (UNESCO) will host a celebration at its Paris Headquarters on Thursday, convening representatives from all corners of the world for discussions on how cities can combat the climate crisis, create more inclusive urban spaces, and contribute to technical innovation. 

Cities provide a wealth of opportunities, jobs included, and generate over 80 per cent of gross national product across the globe, according to UN estimates. Urban areas also account for between 60 and 80 per cent of all energy consumption, despite only occupying three per cent of the planet’s surface and are responsible for three quarters of all greenhouse gas emissions.

In addressing these pros and cons, the Organisation has advocated for a “people-centred” development model, and aims to “re-humanise cities” in the face of trends impacting them, from population growth, demographic shifts, and increasing the risk of disasters induced by climate change. 

This year’s theme: “Changing the world: innovations and better life for future generations” spotlights the role of technology and young people in building sustainable cities. To do so, Thursday’s commemorative event will be organized along four key discussion themes: ‘Cities 4 Sustainable Development Goals (SDGs)’, ‘Cities 4 Climate Action’, ‘Cities 4 Communities’, and ‘Cities 4 the Future’.

In line with its multidisciplinary mandate, UNESCO’s 2004 Creative Cities Network continues to harness the various ways cities spanning the globe are placing creativity and cultural industries at the heart of their development plans. 

From gastronomy in Tucson, Arizona, to design in Nagoya, Japan, the network engages more than 246 cities, which integrate creative approaches in their development plans, 66 of which UNESCO announced as newcomers on the World Day. See the complete list of cities, and their creative undertakings here.

For World Cities Day this year, UNESCO is partnering with the UN”s Food and Agriculture Organisation (FAO)UN-Habitat, and refugee agency (UNHCR) to amplify the concerted action of the United Nations for cities alongside their planners and other urban players. 

The UN-proclaimed World Day serves as a call for States, municipalities and city dwellers to work together for transformative change and sustainable strategies for cities, as urbanization continues to swell. 

UN chief calls cities a battleground for climate crisis

Secretary-General António Guterres explained in a statement attributable to his spokesperson,  that “the choices that will be made on urban infrastructure in the coming decades…will have decisive influence on the emissions curve. Indeed, cities are where the climate battle will largely be won or lost.” 

From electric public transport to renewable and energy and better waste management systems, cities are “hubs of innovation and creativity, and young people are taking the lead.” 

In addition, he highlighted that World Cities Day comes as “urban October” concludes, a month dedicated to raising awareness of urban challenges, and successes in sustainability. 

“Let us commit to embracing innovation to ensure a better life for future generations and chart a path towards sustainable, inclusive urban development that benefits all”, he encouraged.

Spotlight on cities

Over half the world’s people live in cities. As more and more people move into cities from rural areas a number of environmental and social challenges arise, including overcrowding in slum areas, poor sanitation and air pollution. However, urbanization can also present great opportunities and is a critical tool for achieving the 2030 Agenda for Sustainable Development if done right.

Cities have always been drivers and incubators of innovation. It is often said that the battle for achieving the Sustainable Development Goals will be won or lost in cities. For this to happen, cities will have to continue to drive innovation to achieve a lasting impact in communities and to ensure that “no one and no place” is left behind.

This year’s World Cities Day, hosted by the City of Ekaterinburg, Russian Federation and co-organized by UN-Habitat, the Shanghai People’s Government and the City of Ekaterinburg, will focus on technology and innovation: digital innovations that can be used for urban services to enhance people’s quality of life and improve the urban environment; technologies for building more inclusive cities; opportunities for generating renewable energy and; technologies that can promote social inclusion in cities.

This year’s theme for World Cities Day on 31 October is “Changing the world: innovations and better life for future generations.”

Technologies such as artificial intelligence, virtual, augmented and mixed reality and the internet of things present efficiency and communications opportunities requiring new governance frameworks. This rapid rate of innovation also puts pressure on urban policymakers and managers to strengthen their capacity when it comes to understanding, procuring and regulating new technologies.

The UN Environment Programme (UNEP) works in partnership with UN-Habitat and others to promote the sustainable development of cities.

Jointly with the World Health Organization, the Climate and Clean Air Coalition and the World Bank, we lead BreatheLife, a global campaign to mobilize cities and individuals to protect our health and our planet from the effects of air pollution.

Together with Cities Alliance, the United Nations Human Settlements Programme (UN-Habitat) and the World Bank, we launched the Knowledge Centre on Cities and Climate Change (K4C), an online repository of information on climate change that advocates informed decision-making in local governance.

Check out UNEP’s work with partners relating to cities, covering green spaces (and the importance of trees in soaking up pollution), sustainable transport, district heating and cooling, sustainable waste management, sanitation and more.

Cities Around the World Want to Be Resilient and Sustainable. But What Does This Mean?

MD Staff

Cities around the world, large and small, face common challenges, especially due to rapid urbanization and climate change. According to United Nations (UN) estimates, four billion people – more than half of the world’s population – live in urban areas today. By 2050, over two-thirds of the global population will be urban, challenging cities to meet accelerating demand for affordable housing, well-connected transport systems and other infrastructure and services, as well as jobs.

In addition, rising global temperatures increase the risks of rising water levels, landslides, droughts, hurricanes, and other disasters. Without urgent action, these climate impacts could push an additional 100 million people into poverty by 2030, according to the World Bank. 

The good news is that, armed with knowledge and creativity, urban centers are finding ways to tackle new and old problems alike, with fewer losses and greater recovery capacity – in other words, creating “resilience”.

The Catalyzing Sustainable Urban Futures global conference held recently in São Paulo, Brazil, which was co-hosted by the São Paulo City Hall, the Sustainable Cities Program, and the World Bank’s Global Platform for Sustainable Cities (GPSC), with the support of the Global Environment Facility (GEF), looked closely at this topic of “resilience”.

Representatives from four continents examined three global issues, with sustainability and resilience as an ever-present backdrop. The first was climate change, a concern that mayors can no longer afford to sidestep. According to the World Bank, cities consume about 2/3 of the world’s energy and account for over 70% of global greenhouse gas emissions.

The second issue was the need for more green spaces – think about public parks with trees, birds, bees, and other species. Today, around one million animal and plant species are threatened with extinction, eroding the foundation of our shared livelihood, society’s ability for adaptation, and nature’s capacity to store carbon. Green spaces do not only help cities mitigate and adapt to climate change, but also serve as important places for human-wildlife coexistence – and a home for conserving urban biodiversity.

Third, there was a constant discussion about solid waste management. Without it, rivers will overflow and the air will be polluted by harmful substances, among other problems. With it, millions of people, including those in the recycling industry, will be presented with new opportunities.

Mitigating and adapting to climate change

Today, 90% of urban expansion takes place in developing countries, and much of it occurs near natural hazards, rivers, and coastal regions, in the form of informal and unplanned settlements. A lack of infrastructure and proper land use plans exacerbates the risks facing residents, especially in view of climate change. Thus, several cities are now devising their own mitigation and adaptation plans. São Paulo, for example, is set to launch its plan in June 2020.

Another Brazilian city, Recife, already has a plan in place, in preparation for the city’s 500th anniversary celebration in 2037. One-third of the local population lives in hill areas susceptible to disasters; another third of the population resides at sea level, which means that flooding is a threat.

“With the participation of civil society and the general population, we have compiled a strategic plan based on a set of urban and environmental plans containing a series of initiatives to mitigate [disaster risks], increase resilience, and adapt to the consequences of the climate crisis,” stated Mayor Geraldo Júlio at the conference.

Plans in developed countries are even more ambitious. Paris, France, has pledged to become a carbon-neutral city by 2050, enacting 500 measures in various industries, such as construction, transport, energy, and food. These measures include goals such as using only green energy (biomass, wind, and solar), banning diesel cars by 2024, and eliminating all cars running on petrol fuels by 2030.

Less asphalt, more forests and parks

“With fewer cars on the street, we will not need as many parking lots or as much asphalt,” said the Deputy Mayor of Paris, Pénélope Komitès. “We can, for example, use garage buildings to plant urban forests that help regulate the temperature.”

Just like Paris, the expansion of green spaces is becoming a trend, from China to Paraguay. These spaces capture carbon and improve air quality, among other benefits. Such changes are most welcome in Chinese cities like Ningbo, which has over 40 square kilometers of protected areas despite its population of 8 million people.

In Latin America, the city of Asunción, Paraguay, is planning to build a green urban corridor – at least 35,000 hectares in size – to take better care of its biodiversity, especially birds. The project is in the preliminary phase.

Parks also help reduce heat, a much-needed improvement in a city like Caruaru in the Brazilian state of Pernambuco, where a linear park (i.e., longer than it is wide) will be built with a bike path connecting 14 neighborhoods, with the potential to benefit 140,000 people.

Together, these measures create opportunities for cities to deliver growth that is green, low carbon and competitive – and to build societies that are resilient, inclusive, and livable.

Waste remains rather unsustainable

According to the World Bank report What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050, in 30 years the global rate of waste production will be double the growth rate of the population. “Cities and countries are developing rapidly, but without suitable systems to cope with changes in the waste disposed of by citizens,” the study highlights.

Against this trend, São Paulo is gradually enacting initiatives and setting goals to alleviate the problem. For example, this year the local government joined the New Plastics Economy Global Commitment to ensure that 100 percent of plastic packaging can be recycled or reused by 2025.

In addition, there is an initiative in place in São Paulo to increase composting yards. Currently, there are five composting yards that receive waste from public markets with a capacity of up to 10 tons / day. By the end of 2020, the local government has promised a total of 17 composting yards to treat 100 percent of the waste from the more than 800 open markets held each week in the state capital.

Composting yards, waste disposal eco-points (available in São Paulo and Caruaru), or simply improved urban sanitation systems (as in the more precarious neighborhoods of Abidjan, Côte d’Ivoire) are among the various solutions that can be adopted by cities around the world to boost sustainability and resilience. Granted, these ideas are not always easy to implement and can be rather expensive. However, according to the What a Waste 2.0 report, the cost of inertia tends to be much higher for both the environment and the poor.
