As part of #Ukrainability project together with @htenkanen.bsky.social, @ollejarv.bsky.social, and Tiina Rinne we study how people use cultural ecosystem services in Ukraine and how they perceive the quality of these experiences during the full-scale Russian invasion.

A study in Nature Communications shows that widely used global population data heavily underestimate rural populations. If not carefully considered, these errors could cause inequitable access to resources and services for rural communities around the globe. https://go.nature.com/4iDkyKr 🧪
This is figure 8, which shows the bias percentages for each of the five population grids in the 35 countries with evaluated rural areas.

🌍 Global population maps fail rural areas

Gridded population datasets systematically underestimate rural populations - by up to 84%.

This could impact policies on resources, healthcare, and disaster planning. Better rural census data is urgently needed.

Is the world population bigger than we thought? New research shows global population datasets massively underestimate rural populations—by 53% to 84%! This could mean too few resources for healthcare, infrastructure & disaster response in rural areas. Read more: www.aalto.fi/en/news/sign...
“Significant proportion” of world’s rural population missing from global estimates, says study | Aalto University
Global population datasets, crucial for decision-making by governments and institutions, may underestimate rural populations by as much as 53% to 84%, reveals an Aalto University study.

📢 Our latest article led by @josiaslr.bsky.social was just published in Nature communications! Our study reveals that the global gridded population datasets contain systematic negative bias in rural population. Read more from the thread below and the full paper here: www.nature.com/articles/s41...

@htenkanen.bsky.social our @digigeolab.bsky.social alumni, currently at @aalto.fi is presenting his research on #LowCarbon #Mobility.

Take-aways:

#decarbonisation and changing #human behavior is extra challenging.

Still, most everyday car trips are 5 km or shorter, and change is possible.

The article uses various open source tools and also delves into the planner’s perspective on interactive online visualization tools. We developed an online tool to visualize our data and assessed its usefulness for planning purposes.💡 The online tool is openly available here: equity.gistlab.science

New paper out at CEUS! We investigate spatial #accessibility and #transport #equity at national level in Finland! 😊 The work was lead by the brilliant Matti Pönkänen and in great collaboration with Miloš Mladenović! 👏 Openly available at doi.org/10.1016/j.co... #GIScience
