In recent years, the floods in canal cities have become more frequent and severe because of sea-level rise, sinking ground, saltwater intrusion, and strong tides from the sea. The floods usually last only a short time (2-4 hours), but they can still damage buildings, disrupt daily life, and make it harder for people and tourists to move around the city. Climate adaptation means policies or physical changes designed to allow people and cities to "live with floods" rather than trying to prevent seawater intrusion at all costs. Methods include, but are not limited to, raising the ground level of public squares, waterproofing and elevating architectural structures, replanning urban spaces, and even establishing localized, decentralized drainage systems. Traditional flood defences are hard-engineering measures that try to keep water out, such as barriers, gates, dikes, and seawalls. The best-known example, in Venice, is the MOSE (Modulo Sperimentale Elettromeccanico) system, a mobile barrier at the lagoon inlets, which has quickly protected the city in several high-tide events but is also criticized for cost, maintenance, and ecological impacts

Urban-to-rural migration is the process of moving out of a big city to a less developed or modernized region in the country.

The host of the Olympics is elected by the members of the International Olympic Commission (IOC) through a secret ballot from the countries that submit their bids. Different countries bid for different Olympics. For example, Paris was elected as the host city for the 2024 Summer Olympics last 2017 while Milan and Cortina d'Ampezzo, Italy was selected to host the 2026 Winter Olympics last 2019.

Hanoi plans to ban motorbikes in core districts after 2025, five years earlier than an earlier plan, in order to reduce traffic congestion and emissions. The capital has around 5.6 million motorbikes and 600,000 automobiles. Currently, in Hanoi, the public bus system plies 140 routes, meeting an estimated 31 percent of total demand. The recently opened Cat Linh-Ha Dong metro service, along with the proposed Nhon-Hanoi Railway Station route, would each be able to meet 5-7 percent of travel demand in the city, according to an expert.
