Sustainable City 2021

15th International Conference on Urban Regeneration and Sustainability

Post Conference Report

5–7 October 2021


Sustainable City 2021

With due consideration to our delegates’ well-being, but also believing that the scientific community should not be stopped from accessing and communicating new research, WIT decided that Sustainable City 2021 should take place as an online rather than a live event in Bilbao, Spain, as originally scheduled.

The conference was organised by the Wessex Institute, UK, represented by Dr Stavros Syngellakis.

The conference series, which started in Rio, Brazil in 2000 is well-established and always attracts a wide, international spread of delegates. The challenge of planning sustainable contemporary cities lies in considering the dynamics of urban systems, exchange of energy and matter, and the function and maintenance of ordered structures directly or indirectly supplied and maintained by natural systems. The task of researchers is to improve the capacity to manage human activities, pursuing welfare and prosperity in the urban environment. Any investigation or planning on a city ought to consider the relationships between the parts and their connections with the living world. The dynamics of its networks (flows of energy matter, people, goods, information and other resources) are fundamental for an understanding of the evolving nature of today’s cities.

Opening of the Conference

The conference was opened by Dr Stavros Syngellakis who welcomed the delegates to the event.

Q&A Live Zoom Session

Conference delegates were invited to participate in three Q&A Live Zoom Sessions which took place on 5th, 6th and 7th October 2021. These friendly sessions were a great opportunity for participants to interact with each other and ask authors questions about their papers.

Papers presented at this conference are published in Vol. 253 of the WIT Transactions on Ecology and the Environment (ISSN 1743-3541). Papers presented at the meeting are available Open Access in the eLibrary of the Wessex Institute ( from where they can be freely downloaded by any interested parties.

A few papers were selected for publication in the International Journal of Transport Development and Integration. This Journal covers all transportation modes and the general topic of transport systems, with particular emphasis on their integration and harmonisation.

Closing of the Conference

We are very sorry that we were not able to meet our delegates in person this year.

We would like to thank the delegates for participating in the event and look forward to meeting them at the next conference in the series which is due to be reconvened in 2022.
