Overcoming Challenges to Build Resilient and Future-Ready Cities
With more than half of the global population now living in urban areas, cities are at the forefront of the fight against climate change. A dense population places enormous pressure on a city’s sustainability, adaptability, and resilience. Additionally, the climate impact of cities is significantly disproportionate—while cities occupy only about 3% of the earth’s surface, they consume around 70% of global energy.
The Urban Challenge
By 2050, it is projected that 70% of the human population will reside in cities. This rapid urbanization presents unique challenges. To remain livable and capable of coping with climate risks such as rising sea levels and extreme weather, growing cities must adopt sustainable and climate-resilient infrastructure. At the planning level, urban infrastructure needs to be weather-proofed in anticipation of more frequent extreme weather events, such as those that lead to flooding.
For instance, in 2020, the Singapore government launched a S$5-billion Coastal and Flood Protection Fund to enhance drainage and flood prevention infrastructure. This initiative includes the construction of seawalls, tidal gates, and revetments to defend against rising sea levels and erosion. Singapore’s iconic Marina Barrage serves as a successful example of such measures, preventing flooding in the low-lying central city area while also forming a new reservoir.
Globally, more than 100 countries have pledged to achieve net-zero gas emissions, with most aiming to reach this target by 2050. To meet this commitment, the world must accelerate the transition to renewable energy sources and low-carbon building materials, such as low-carbon cement and steel. Enhancing building efficiency through energy-efficient lighting, heat pumps, district cooling, and other innovative green solutions is also crucial for scaling impact.
New York City exemplifies a city undergoing a green transformation. In 2012, the city was awarded the Lee Kuan Yew World City Prize for its holistic, systems-based approach to creating a greener and more resilient urban landscape, particularly given its aging infrastructure. The city adopts an interdisciplinary strategy that integrates land use planning, transportation investment, environmental stewardship, and public health.
However, not all cities have the resources to implement such comprehensive measures. Many of the sustainable solutions and technologies needed to achieve net-zero emissions by 2050 are still not ready for large-scale deployment.
