Innovative Urban Planning Solutions in Asian Megacities

Asia’s rapid urbanization, characterized by the emergence of megacities, poses unique challenges and opportunities. Over half of the world’s largest cities are in Asia, a region that is home to 12 megacities as of 2015, with its urban population surpassing the rural one by 2022. This urban growth is a significant factor in the region’s economic landscape, with Asian cities contributing to over 80% of the GDP in many countries. To address these challenges, innovative urban planning solutions are being implemented across these megacities, focusing on sustainable development, efficient infrastructure, and equitable living conditions.

Economic Impact, and the Role of Asian Cities

The landscape of Asian urbanization is characterized by its scale and speed. The region’s urban expansion not only signifies a shift in demographics but also has profound economic implications. Cities in Asia and the Pacific are pivotal to their national economies, generating approximately 60% of the GDP from just 600 cities. This economic significance underscores the need for innovative urban planning strategies to manage growth effectively, balance development, and ensure sustainability.

The future productivity and stability of the region heavily depend on the quality and efficiency of its urban centers. In India, for instance, it is anticipated that by 2030, urban areas will account for 70% of new jobs and a similar percentage of the country’s GDP. The Asian Development Bank (ADB) Urban Operational Plan 2012–2020 even predicts that the economy of Delhi will surpass Malaysia’s current economy. Moreover, the economic significance of second-tier cities is rising. While the world’s 23 megacities contribute 14% to global GDP, this is expected to decrease slightly to just over 10% by 2025. In contrast, around 577 second-tier cities, with 407 in developing countries, are projected to contribute approximately 50% to the global GDP, indicating a shift in economic power.

Asia’s Urban Challenges: Strain Under Growth

The economic dynamism of Asian cities has been a pivotal factor in lifting millions out of poverty. However, this rapid growth brings substantial challenges. These urban centers are expected to accommodate an additional 1.1 billion people within the next two decades, leading to a surge in urban slum populations, projected to reach nearly 700 million by 2015. Cities in Asia are currently grappling with severe issues such as environmental degradation, traffic congestion, inadequate infrastructure, and a scarcity of basic services like water supply, sanitation, and waste management. The primary challenge lies in sustaining economic growth while simultaneously developing sustainable, livable cities for all residents. The transformation required is immense, moving from the current state of chaos, pollution, inequality, and financial constraints to a future where cities are competitive, green, and inclusive.

Innovative Solutions for Sustainable Urban Development (by Asian Development Bank)

Urban Mobility and Energy Efficiency

ADB recognizes urban mobility as a vital catalyst for development, providing essential access to jobs, education, healthcare, and markets. A key initiative in this area is the promotion of low-cost urban mobility solutions, such as Bus Rapid Transit (BRT) systems. These systems enable a broader range of cities to afford quality public transport. A notable example is the ADB-financed BRT system and cycleway in Lanzhou, China, which began operations in January 2013. ADB is also instrumental in financing public transport and pedestrian networks in cities across Asia, including Dhaka, Davao, Ha Noi, Ho Chi Minh City, Jaipur, Kathmandu, Ulaanbaatar, and Vientiane.

In the Philippines, ADB’s efforts are focused on transforming the public transport sector through the promotion of electric vehicles, particularly electric tricycles (e-trikes). With approximately 3.5 million conventional combustion engine tricycles and motorcycles in the Philippines, there is a significant environmental impact. ADB’s project aims to facilitate the adoption of 100,000 e-trikes over the next five years, offering a solution with no noise and zero tailpipe emissions, and the advantage of charging during off-peak electricity hours.

In response to the anticipated surge in energy consumption, where Asia is expected to use over half of the world’s energy supply by 2035, ADB supports transformative renewable energy projects. This initiative is crucial for the region’s transition to low-carbon, sustainable growth. With buildings and industries currently consuming 85% of the region’s electricity, urban transformation through enhanced energy efficiency is vital for future energy security. ADB advises that immediate interventions in public buildings, industries, and municipal lighting can substantially improve energy efficiency. Investments ranging from 1% to 4% of overall energy sector spending could address up to 25% of the projected increase in primary energy consumption.

In the Philippines, ADB supports a project focused on improving demand-side energy efficiency. This project includes financing lighting retrofits in government buildings and the installation of 9 million compact fluorescent lamps (CFL) in private homes. These improvements have not only reduced energy production costs and decreased oil imports but have also significantly mitigated emissions of harmful pollutants such as sulphur dioxide, nitrogen oxides, particulate matter, and carbon dioxide.

Environmental Initiatives

In Bhopal, India, the Asian Development Bank (ADB) has launched an innovative water project that significantly improves the city’s water supply and enhances the environmental quality of one of its top tourist attractions. This Urban Water Supply and Environment Improvement Project has been a boon for 5.3 million people by improving their access to water. Additionally, 500,000 people have benefited from enhanced sewerage and sanitation, and 4.7 million people now experience improved solid-waste management.

A key aspect of this project is the rehabilitation of six pumping stations at Bhopal’s Upper Lake. This lake is renowned for its scenic beauty, diverse bird life, and boating facilities. As a result of the project, the lake now supplies six million gallons of clean water daily, significantly reducing pollution and enhancing the overall quality of life in the city.

In addressing the challenge of urban flooding, ADB emphasizes the importance of assessing demographic and geographic vulnerabilities. There is an urgent need to enhance capacities for disaster risk reduction, particularly in Asia, a region prone to natural disasters. ADB supports the use of advanced meteorological observation systems for more accurate predictions of threats like flooding. Satellite-gathered precipitation data is instrumental in providing early warnings to populations in high-risk areas. Moreover, high-resolution images of inundated areas are crucial for effective rescue and recovery operations post-flood.

Incorporating water-related disaster risk reduction and management strategies, especially community-based approaches and climate change adaptation measures, is essential in urban planning. By screening infrastructure investments for climate risks, cities can not only mitigate disasters but also adapt more efficiently to the anticipated impacts of climate change.

In Vietnam, an ADB-funded project has collaborated with women’s organizations in urban areas to address sanitation and wastewater challenges. The Central Region Urban Environmental Improvement Project has improved living conditions in six medium-sized coastal towns. This was partly achieved through a community awareness program overseen by local chapters of the Vietnam Women’s Union.

The project provided start-up capital for a household sanitation credit scheme, operating as a revolving fund. This initiative led to the installation of new latrines and septic tanks in approximately 2,230 houses, significantly improving sanitation and human dignity.

To further advance sanitation access in the Asia-Pacific region, ADB and the Bill and Melinda Gates Foundation have established the Sanitation Financing Partnership Trust Fund under the ADB-administered Water Financing Partnership Facility. This trust fund focuses on supporting innovative sanitation solutions, including policies, business models, and technologies, to enhance non-sewer sanitation and septage management in Asia.

Waste Management and Urban Resilience

In the People’s Republic of China, ADB supports innovative solutions to municipal solid waste challenges. In 2009, ADB entered into a private sector agreement, lending up to US$200 million to China Everbright International Limited Company. This funding is for developing waste-to-energy (WTE) plants in over 20 secondary cities across the country. These plants have significantly increased the annual municipal waste processing capacity to more than 8 million tonnes. In 2012, these WTE plants generated over 1,300 million kWh of green electricity, substantially reducing carbon emissions.

ADB’s approach to integrated urban planning is evident in its project in Bharatpur, Nepal. This initiative aims to improve the city’s environment while making it more climate-resilient, thereby attracting residents and reducing congestion in the capital city of Kathmandu. This spreads economic development more evenly across the country.

The ADB project in Bharatpur has enhanced municipal planning and upgraded infrastructure for water supply, drainage, and sanitation. It also supported the municipal government in transforming the city’s riverside into a green space. This includes a cement embankment that protects residential land from erosion and provides accessible steps to the river, safeguarding against landslides while making the city more livable.
