Great update on urban populations around the world in a user-friendly #GIS. Perfect for #geographyteacher Spoiler alert: It's Jakarta, Dhaka, Tokyo (2025)

I've updated the World City Population interactive map with the new UN World Urbanization Prospects 2025 data. The WUP 2025 has a new methodology resulting in substantial changes to population estimates for the world's largest urban agglomerations- luminocity3d.org/WorldCity/

Very useful, since all cities defined by "contiguous areas of high density urban land (above 1,500 persons per km2)"

It’s been long overdue (~1 month!) but I presented my initial findings in Social Media Geopolitics session at #AAG2025 in Detroit last month—all thanks to @casaucl.bsky.social Doctoral Student Conference Fund. My study revolves on digital participation in Jakarta, using government-app called Qlue.

Important report on the planning system from @msingerhobbs.bsky.social Too many homes are being built that lack good transport links and lock in costly car dependence. We need more and better planning to guide development and ensure homes and infrastructure are built in the right places.

🧱 | NEW REPORT: Instead of stripping back planning regulations to 'get Britain building,' this new report from @msingerhobbs.bsky.social argues we need a stronger, better resourced, planning system.

Today I ventured south to Glen Shee, in search of hilltop sunshine. Turns out my choice of hill, Creag Leacach, was right on the dividing line between fog and sun. This made for spectacular cloudscapes throughout the day, changing every few minutes 🙂

🚀 Job Alert!!! 🚀 The first in a series of long term posts within the SDRUK Geographic Data Service which will launch next year -this one is based in London - https://buff.ly/4fSyChU and builds on the work that we have done over the past ten years as part of the CDRC.

A short thread on the data used in the NEF report on car dependency by me and Emmet Kiberd, released yesterday. The report looks at the exact locations of all new homes in England, and shows that they are being built in increasingly car dependent areas. 1/4

Super useful list of planning and housing accounts to follow on bluesky by @barneystringer.bsky.social -

Glad to see this published! @citygeographics.bsky.social’s working paper inspired our @neweconomics.bsky.social analysis and report on car dependency, also released today 👏🏼

New open access paper - can we develop London's Green Belt sustainably to tackle the housing crisis? Analysis using EPC and travel sustainability data - www.sciencedirect.com/science/arti... @casaucl.bsky.social

Highlights from the @neweconomics.bsky.social report on car dependency. The report shows that new homes in England are increasingly located in car dependent areas with poor transport infrastructure. The triangle in the figure indicates car dependency of median home from each period. 1/6
