Barcelona October 2023
For a long time, international gatherings hadn’t taken place in Europe. However, in fall 2023 our Land Economics Weekend was organized in Barcelona for the first time and it was a great success.
We have renamed this the X -LEW as over 150 members from the USA and Canada crossed the Pond to meet their European colleagues and because it lasted one day longer. (eXtended -LEW) . Barcelona is the first Spanish spot for international tourism and the third European LAI chapter, founded after the LAI Madrid and LAI London chapters . Therefore, this setting was a great opportunity for both learning and growing professionally, and enjoying the local culture with our local community members. -

Municipalities working in cooperation. Finding the missing middle. How low housing supply hurts affordability and affects homelessness. Recrafting a master planned community for today’s needs. Reviving an entertainment district. Bringing desert to development, responsibly. And zoning’s unintended consequences. Those were some of the themes that resonated with the nearly 100 attendees at the 2024 Land Economics Phoenix Gathering, held October 16-18 and hosted by the Lambda Alpha International (LAI) Phoenix Chapter. Three days were devoted to LAI executive planning, recognizing outstanding contributions, and exploring and gaining insight into topics relevant to the Arizona Valley of the Sun – the booming West Valley, housing affordability, and responsible water use.

The Montréal Land Economics Gathering (our re-branded LEW) was a great success.
