The cost of rebuilding Ukraine, and other urban transformation stories you need to read

Saturday, 24 February marks two years since the Russian invasion of Ukraine began in 2022.

The World Bank, United Nations and European Commission estimate the cost of reconstruction and recovery after two years of war to be around $486 billion, according to a new joint report. This is an increase of $75 billion from last year.

Direct damage from the war has reached almost $152 billion, the third Rapid Damage and Needs Assessment found.

Included in the losses are around two million housing units destroyed or damaged – 10% of Ukraine's housing stock of Ukraine – as well as vital infrastructure, such as 8,400km of motorways and major roads, and almost 300 bridges.

At the World Economic Forum's Annual Meeting in Davos, members of the Davos Baukultur Alliance met to mobilize support and provide expertise to help back reconstruction efforts.

The Alliance is collaborating closely with Anastasia Bondar, Ukraine’s Deputy Minister for Culture and Information Policy to convene key rebuilding experts and supporters.

Speaking to the Forum, Bondar said: "The idea is to build back better. We will be competing for those people who fled to come back ... We need to get those people back and we want them back. We have to provide something that is more attractive compared to what we had before."

Austin-Round Rock and Idaho Falls have topped the list of the US' best-performing cities in 2024.

The rankings, compiled by thinktank The Milken Institute, are split into large and small cities, which are then rated against 13 measures that fall into three categories: labour market performance, high-tech impact and access to economic opportunities.

Austin-Round Rock regained the top spot as the best-performing large city for the first time since 2013, due to rapid growth in jobs, wages and technology.

Idaho Falls, the best-performing small city for the second year in a row, has "experienced balanced growth, with a strong performance across all components of the ranking".

The measures include community resilience and households with affordable housing costs.

To put a spotlight on the challenges around urban affordability, the World Economic Forum's Global Future Council on the Future of Cities has published a collection of articles, Reshaping affordability: interventions for inclusive and liveable cities.
