Can a City Feed Itself?
In Paris and elsewhere, cities are exploring the economic and environmental benefits of building-based agriculture and racing to protect farmland at the urban edge.
Beach cleanup goes high-tech
Plastic-munching robots, floating drones and other “smart” contraptions are starting to ply beaches and waterways, systematically removing dangerous debris left by summertime revelers.
Why Youth Should Be Involved in the Planning of Smart Sustainable Cities
One of the most critical tasks to achieve the Sustainable Development Goals (SDGs) is making cities hospitable, productive, and healthful places to live, as called for by SDG 11.
Why Smart Cities Are the Path to a Sustainable Future
Smart cities are already here, but they’re no longer just a nice-to-have if we want to protect the world.
Two new guides for climate-smart cities
How cities manage water is one of our planet’s greatest challenges. Faced with new water and climate extremes, cities need to radically rethink every aspect of infrastructure, urban planning, and water governance. In two new policy briefs, SIWI experts show how cities can succeed and why this is a shared responsibility.
The Future of Infrastructure: Solar Roadways and Smart Cities
As we look toward the future of infrastructure, two key concepts stand out: solar roadways and smart cities. These innovative ideas are set to revolutionize our urban landscapes, transforming the way we live, work, and interact with our environment.
Smart cities and energy usage: where is most electricity wasted?
In 2050, around 70% of the world’s population will live in urban areas compared with 57% today. Cities are, therefore, our future and the board on which the transition towards net zero energy will be developed. Where do they waste more energy?

Why are micro-mobility companies failing to take off?
The micro-mobility business, a field in transportation that involves a range of light vehicles such as scooters, PMVs in general or shared bicycles, is just not taking off. What are the obstacles? What are the main failures in terms of implementing this form of mobility, which, on the other hand, is necessary?
Could an ultra-white paint cool the cities of the future?
Recently, Xiulin Ruan, a Purdue University professor of mechanical engineering, created the whitest paint on record, capable of reflecting 98.1% of sunlight. His plan: paint entire cities in order to cool them.
