🚨 New Article Alert! 🚨Excited that I published my first paper, emphasizing that informal settlements and sprawl are not the same for #secondarycities in Africa @SustainableCit8. Together with @Michiel_Daams and @MonikaKuffer 😊 ➡️🧵

📢 Reminder: Noch 1 Woche bis zur Deadline! Reicht eure Beiträge für meine Session bei der DGD-Tagung 2025 in Wiesbaden ein: "Geodaten: Nutzen und Potenzial für amtliche Statistik & Survey-Methodik" Deadline: 20.12. Call for Papers hier tinyurl.com/dgdgeo #spatialdata
Over COP29, the World Bank published more results from our Urban Climate Finance analysis for 2019-2022.
Avg. annual climate finance to urban areas and cities has gone up 30% since our last analysis.

This ESA post provides a nice overview of how our research challenges some common assumptions about informal settlements in rapidly growing cities, especially in Sub-Saharan Africa. With @Michiel_Daams and

What’s the trade-off between housing people and preserving green space?
Melanie Krause presents interesting findings at #ERSA2024.
Eg., in high-income countries more residents don’t mean less green space ➡️ are cities able to densify and preserve by building up? #urbangrowth

The UN Statistical Commission has adopted a new definition of urban areas, developed by @DijkstraLewis in collaboration with a raft of IOs.
This new definition improves the measurement & comparison of urban and rural phenomena, facilitating analysis and policy-making.

3/4 We found that the impact varies widely across different cities. Informal settlements show 12.8% lower network connectivity in pooled results, indicating sprawl in some cities. 🏘️➡️🛣️❓Yet, in important secondary cities including Arusha and Dodoma, this effect does not show.
4/4 Informality isn't always linked to sprawl. And of course, formal development plays a large role in sprawl globally. This complexity suggests more tailored interventions are needed for sustainable urban development. 🏗️🌿 #UrbanGrowth #sprawl #remotesensing
This.
Love the planet…?
…allow more people to live in walkable, transit rich neighborhoods.

The kin' of Family #Demography 👑 Congrats to @PolizzAn for winning the best @PopAssocAmerica poster prize #PAA2024 👏🏆

Yes, suburban areas have gained population, but depending on what’s “#urban”, urban areas have considerably gained more in Germany! Fortunate to present current work, comparing building-based to other urban-rural classifications at #PAA2024 in Columbus ➡️ tinyurl.com/suburbangrid

Over the last 6 decades, Sub-Saharan #Africa has been among the world’s fastest urbanizing regions. By 2050, the population residing in SSA's #urban centers is projected to exceed 1.26 billion, surpassing today's figures by more than 2.5 times. This accelerated urban growth poses significant implications for the development of a region where over 1/3 of the population lives in extreme #poverty.
To fill the gaps on accurate information regarding urban settlements in Africa and overcome differences in official definitions of urban areas, this #research uses digitized maps of buildings footprints from high-resolution satellite imagery. The results reveal that #urbanization is usually higher than official data suggest, and that a doubling of an urban area’s population is associated with a more than doubling of its built-up area.

Excited to finally see our tool online! You can now explore 30 years of #Migration history between world regions, countries, and within #Germany on our @bib_bund website. 🌏
Shout out to @nikolasander, @tamilwhy, and @vis_kom for the great team work. 💪
1/2 Today, on #MigrantsDay, we are excited to launch the 'Global Flow of People 2.0'. The interactive & easy-to-use #tool allows you to explore patterns & trends in (global) migration over time. Try it out & browse through 30 yrs of #migration history.

Thanks (!) to @gesis_org, @StefanJuenger for organizing a super rich workshop on „Earth Observation Data in the Social Sciences“. How to use remote sensing data to learn about population growth in urban and suburban areas? I presented upcoming work, showcasing this in Germany.
