Summary
Researchers emphasize the importance of accurate population data for effective decision-making and resource allocation, particularly in the context of healthcare and disaster response. Professor Andy Tatum, a spatial demography expert from the University of Southampton, highlights the challenges faced in collecting reliable population data, especially in countries with outdated census information. He notes that many regions lack current data, which can hinder the equitable distribution of essential services like vaccinations.
Tatum discusses the use of innovative data sources, such as satellite imagery and mobile phone tracking, to update population estimates. He cites examples from the UK, where student populations fluctuate significantly during the academic year, and from the Democratic Republic of the Congo, where discrepancies in population figures complicate resource planning during health crises like Ebola.
The conversation also touches on the anticipated impacts of climate change on population movements, with increasing numbers of people likely to migrate due to uninhabitable conditions in their home regions. Tatum indicates that organizations like UNICEF utilize their data to prepare for these shifts, underlining the global implications of demographic changes and the necessity for collaboration between researchers and government agencies to address these challenges effectively.
Show Notes
Population data is vital as countries allocate resources. But it is costly to collect and data can quickly become out of date. Andy Tatem is using new sources of data from mobile phones and satellites to produce more accurate population data.

Oceans were the focus at the opening of this year’s British Science Festival in Southampton UK. Professor of Maritime Archaeology Helen Farr describes the first example of long-distance voyaging by Australian Aborigines as they sailed to Australia. While the first evidence of human occupation in Australia is dated at 65,000 years at the Madjedbebe cave east of Darwin, the site is inland and so earlier sites are likely awaiting discovery closer to the coast.
Southampton’s population is 260,000. When 5 cruise ships dock, some carrying 10,000 people, the city’s power demands can be almost 15-20% higher. Then there’s the impact on air quality. Nat Easton is measuring fine particles such as vanadium and arsenic and studying their effects on people’s health. She says local governments in the UK need more power and support to deliver cleaner air to local populations.
Chloroplasts in plant cells and mitochondria in animal cells were once free-living organisms. Now they are organelles fully incorporated in animal and plant cells. So how did this merging take place and how was outside DNA accepted and come to play a vital role in the operation of plant and animal cells? Yan Wong and Alexandra Martin-Geary presented some of these fascinating ideas and the big questions in genetics at this year’s British Science Festival in Southampton.
The rise of eugenics troubles Professor of Psychology, Rebecca Sear, at Brunel University in London. Very powerful, influential, wealthy people are on board with eugenics. It is OK to use gene technology to alleviate maladies, she suggests, but trying to implant the ”gene-for-Harvard” or remove spurious “inferiority” from communities, she avers, is simply the re-emergence of racism.
Across south-eastern Australia, bogong moths seem to be everywhere. A few years ago, it was a different picture: scientists witnessed a population crash, and habitat threats put the species on the IUCN Red List. Are we seeing a bogong bounce-back? Jonathan Webb speaks to Dr Kate Umbers about these incredible critters, the many unsolved mysteries of their lives — and what their future could look like.
