Rapid urbanisation has provided most cities in the world with opportunities to provide more sustainable, vibrant, and prosperous centres 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; Eastern Europe, 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 Takehiko Nakao said.“They can be centres 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.”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: Akinwumi Adesina of the African Development Bank, Suma Chakrabarti of EBRD, and 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 centre 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. President of the African Development Bank, Akinwumi Adesina said, “We are helping to open up rural areas to development as a means of reversing migration trends. To do this, we are investing in skill upgrades, creating jobs, providing access to SME finance for young men and women. Ultimately, we need to create livable and workable cities for the younger generation.”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 centre 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.Adesina called for increased regional development bank cooperation in information sharing, shared learning from existing diagnostic tools, and a joint action plan and collective effort to help create sustainable and livable cities.
