We're joined by Héctor Ochoa Ortiz, who is an OpenStreetMap Board Director & Deputy Secretary, and Dr Barend Köbben, cartography specialist, from ITC.

In this extended conversation, Héctor explains how millions of contributors collaborate to build and maintain a living map, navigate disagreements, and balance local knowledge with emerging AI-assisted mapping tools.

From the ethics of mapping sensitive locations to the relationship between volunteers and commercial users, this is a wide-ranging conversation that examines the technical, social, and governance challenges shaping OSM today and in the future.

In this episode, Chen Song explains her PhD research on the long-term impact of the devastating 2021 Ahr Valley floods in Germany.

While headlines focused on dramatic rescues and destroyed infrastructure, this conversation shines a light on the quieter, often overlooked reality of recovery for older adults.

Drawing on  surveys and conversations with older residents, healthcare professionals, caregivers and community organisations, Chen uncovers how disasters continue to shape lives long after the media has moved on. From anxiety, loneliness and disrupted healthcare to remarkable resilience and community solidarity, this episode reveals the human side of disaster recovery.

As climate change drives more frequent extreme weather events and Europe's population continues to age, understanding the needs of older adults has never been more important. Chen's research challenges us to rethink what recovery really means: not just rebuilding homes and roads, but restoring health, connection, dignity and a sense of belonging.

In this episode, host Brad Hillas speaks with Professor Monika Kuffer from the Faculty of Geoinformation Science and Earth Observation at the University of Twente about her work in urban planning, geospatial data, and its connection to the Sustainable Development Goals (SDGs).

Professor Kuffer discusses how her research contributes to making cities more inclusive, livable, and sustainable. She explains how geospatial data can track inequalities, improve urban decision-making, and empower local communities. She also highlights how data can give a voice to vulnerable communities most threatened by climate change and why, despite advances in AI-powered models, human verification remains essential.

Her personal stories from her career provide eye-opening insights into the challenges of urban deprivation and spatial inequalities.

Topics covered:

• How slum mapping helps urban planning
• The impact of evictions and climate policies on vulnerable communities
• AI and citizen-generated data for more accurate urban analytics
• Why global datasets often fail to reflect reality in deprived areas

Listen now to explore how data, technology, and community engagement are shaping the future of cities worldwide!

Professor Roberts is Honorary Professor at the University of KwaZulu-Natal in Durban in South Africa. She was Co-Chair for Working Group II of the Intergovernmental Panel on Climate Change and the former Acting Head of the Sustainable and Resilient City Initiatives Unit at EThekwini Municipality.

In this episode, Debra and Jelle discuss Open Science - the idea of making scientific research, data, software, and educational resources freely accessible to everyone - and how it impacts collaboration between researchers from the EU and the African continent.

This is Part 1 of a two-part conversation. In Part 2, Jelle and Debra tackle one of Professor Roberts’ most controversial topics: Climate Overshoot. Come back to Geoversity soon to check out that episode! 

But now that we're on track to overshoot the Paris Agreement's target of 1.5 °C of global mean temperature rise, what about the social and humanitarian impacts? 

In this week's episode of Geoversity podcast, we highlight research that looks into some of the factors influencing human and social climate overshoot impacts.

What is the call to action for scientists, governments and humanitarians? Listen now to find out.

In the reconstruction effort that followed, notable differences in the safety of rebuilt homes and businesses emerged. 

In this episode of Geoversity podcast, we discuss recent research that looks into the factors influencing these varied safety outcomes.

Why did some build safe houses, while others did not?

That's the question posed by researchers Aditya Pradana Ganda Saputra, Nina Schwarz and Eefje Hendriks in their paper, Identifying factors influencing housing safety in post-earthquake reconstruction by households in Nepal.

Our first guest is Brian Masinde. 

As humanitarian organisations increasingly use GIS, big geodata, and AI to guide aid delivery, concerns are growing about privacy, bias, and accountability.

In this episode, Brian explains his research on protecting demographically identifiable information (DII) within geo-intelligence workflows while upholding humanitarian principles.

He discusses the risks of demographic profiling, group privacy harms, and biased data-driven systems, along with practical solutions such as geodata triage, auditing, and causal methods for bias detection.

His research highlights how humanitarian organisations can move from reacting to data harms toward embedding privacy and accountability into technology design from the start.

Nowhere is this challenge more evident than on the Indonesian island of Java, home to the endangered Javan leopard—a top predator surviving in a patchwork of fragmented forests surrounded by one of the world's highest human population densities.

In this episode, Dr Andhika Ariyanto explains his research that follows the Javan leopard from the scale of individual animals to entire landscapes.

Using camera traps, ecological modelling, and connectivity analyses, his research investigates how prey availability influences where leopards live, and how future changes such as road expansion or reforestation could affect their ability to move between habitats.

Together, these findings highlight the importance of conserving wildlife beyond protected areas and show how science can help design landscapes where both people and large carnivores can thrive.
