Climate change is one of the greatest challenges of our time. It reflects a growing imbalance between people and the natural systems that support life on Earth. Building a more sustainable future requires more than understanding present-day environmental problems. It requires a deeper perspective on how ecosystems function, how they have changed over time, and how humans have interacted with them over long periods.

As a third-year bachelor student in biological and Earth sciences, I have become increasingly interested in these long-term interactions between climate, ecosystems, and human land use. I have learned that ecosystems are not stable systems, but dynamic ones that continuously respond to changes in climate, fire, and land use. Palaeoecology provides a way to reconstruct these long-term dynamics and place modern environmental change in a much deeper temporal context.

Although environmental change has always been part of Earth’s history, the current situation is characterised by a particularly rapid combination of climate change and human pressure on land systems. This makes long-term knowledge especially important, as it helps us distinguish natural variability from human-driven change and understand whether current ecosystems are within historical ranges of behaviour or entering new states.

Honours Program Thesis Extension

For the Honours Program alongside my bachelor’s degree, I extended my palaeoecology thesis with an interdisciplinary perspective focused on how long-term environmental knowledge can inform future land management. Rather than treating palaeoecology only as a reconstructive science, I explored its role as a bridge between past ecosystem dynamics and present-day sustainability challenges.

As a case study, I focused on the Dahomey Gap in West Africa, a forest–savanna transition zone that interrupts the continuous Guineo-Congolese rainforest belt. This region is not a fixed ecological boundary, but a shifting mosaic shaped over time by climate variability, fire, and human land use.

Scientific Workshop: Getting to the bottom of the Quaternary

July 8, 2026
WDG

The International Continental Scientific Drilling Program (ICDP) Deep Chew Bahir (DeepCBH) drilling workshop took place in Addis Ababa (Ethiopia) between the 30 June and 3 July 2026. The workshop brought around 50 scientists to Ethiopia, with a further 30, or so, in a satellite meeting in Potsdam (Germany) and online. The workshop was lead by Asfawossen Asrat, Verena Foerster, Daniel Gebregiorgis and Stefanie Kaboth-Bahr, and included scientist from 18 different countries (including 5 African countries).

The purpose of the meeting was to, build upon the previous successful drilling of the Chew Bahir basin which raised sediments spanning the last c. 600,000 years (Foerster et al., 2026), and to discuss the opportunities, logistics and requirements to make the recovery of sediments spanning the whole of the Quaternary (last 2.6 million years) from the Chew Bahir basin possible. Obtaining such a record would provide an unprecedented insight into the environmental and climatic change that was the backdrop for the evolution of our genus, Homo.

The skill sets of those attending was as diverse as the challenges and opportunities that undertaking such an epic coring expedition would require. These included the fundamentals of what equipment would be required to recover a sediment core down to depths of 1.2 kms below the Earths surface and what to do with 1.2 kms of sediment once it was recovered; as well as the scientific motivations for doing so from perspectives of hydrology, human-environment interactions and extreme microbial ecosystems.

Over the three days, discussion of the feasibility, ambition and funding was intense, and many steps forward were made in aligning the practical and scientific considerations. It was great to meet everyone and to have a chance to chat about the potential of this exciting project. The next step is to collate the workshop outputs and submit a full proposal to the ICDP in January 2027.

MSc Earth Sciences: Peru field course 2026

July 6, 2026
WDG

As part of the University of Amsterdam (UvA) MSc Earth Sciences we run the course “Field Course Geoecological Systems”. In 2026 we returned to the village of Miraflores in the Lima province of Peru. Partnering with the Institiuto de Montanya (Mountain Institute) in Lima students spent four weeks engaged in participatory research with the Miraflores community. The integration of students within the community was made possible by the work of Mirella Gallardo and Rafa Schmitt.

In this year’s iteration of the course, we had groups of students working on four different topics: (i) water quality, (ii) soil carbon stocks, (iii) microbes and carbon in agricultural soils, and (iv) cultural heritage. The topics of the project were established in advance in consultation of the Mountain Institute and refined during a Town Hall meeting with the Miraflores residents during the first days of the visit.

Through the four weeks of the field work students learnt how to classify soil types, monitor water quality, and read the landscapes geology and geomorphology. Traversing the rugged Andean landscape from our base at c. 3600 meters above sea level up to peaks above 4000 meters. The students also worked with the Miraflores residents to discover their perception and knowledge of the landscape. Following the visits students conducted further analysis of water and soils back in the laboratories at the UvA. Once this work is complete all results will be compiled into a report, in English and Spanish, that will be distributed to participants.

This is the third time this field course has visited Miraflores and this year we were proud to present fliers detailing the key finds of previous years investigation to the community. We would like to thank the community of Miraflores for their continued kind welcome and partnership, and the Yauyos-Cochas National Park for their permission and support to work within this area.

Fieldwork in South Africa

From data to reality

Last year, between April and June, I worked on my bachelor project on the fire history of a site in South Africa called Giant’s Castle. From the Netherlands, I analysed sediment cores by counting charcoal fragments and looking at their shape to determine whether they likely came from grass or wood. The results were largely what you would expect in a mountain grassland. Most of the charcoal came from grasses. At the same time, there were clear changes in the composition of the fuel reflected in the charcoal record. I linked the increase in fire activity to the presence of people, and also observed shifts in the types of fuel being burned over time. It felt like slowly unravelling a story from the past. But it also remained abstract. I was working with numbers, figures, and photos of a place I had never actually been to. I had a sense of it, but it did not fully feel real. A year later, I was standing there myself.

From analysis to experience

For my MSc research, I returned to the same system, but this time physically. In the meantime, I had already expanded my earlier work by looking at dung fungal spores, as an indicator for grazing animals, and pollen to reconstruct vegetation dynamics. But to describe vegetation properly, you really have to see it. After a five-day workshop, which I described in a previous blogpost, I spent a weekend at the home of Prof. Trevor Hill and Prof. Jemma Finch. That weekend turned into something like a crash course in South African life. It even included watching their son play a cricket match. What stood out most to me was how much more outdoor-oriented life felt compared to what I am used to in the Netherlands. After that, I was introduced to the University of KwaZulu-Natal in Pietermaritzburg, where I spent three weeks working in the lab. Interesting work, but I had really come for something else. The field.

Shared Pasts and Shared Futures in New Orleans!

April 21, 2026
cmcmicha

I just attended a symposium at Tulane University organized by Kris Lane and Jason Nesbitt of the Center for Latin American Studies. “Andes + Amazon, Shared Pasts and Shared Futures” was an amazing interdisciplinary experience, with talks from scholars in disciplines ranging from law and history to paleoecology and paleogenetics. But we all had a common goal, which is understanding how human-environment interactions have shaped, and will continue to shape, the immense biological and cultural diversity of Andean and Amazonian ecosystems.

I enjoyed seeing colleagues, meeting new colleagues, and speaking with PhD students who are eager to work in tropical ecosystems. One of my highlights was meeting Bill Baleé, whose work I’ve read since I was a PhD student. He is a historical ecologist who studies how Indigenous people modify Amazonian forests. His knowledge is immense, and he is also an incredibly warm and welcoming person. I am really looking forward to our future collaborations. I think there is strong momentum coming from this symposium, and we plan to put out a volume of articles that show the importance of a multidisciplinary lens for understanding the future of Andean and Amazonian ecosystems. Stay tuned!

Dutch Earth & Environmental Science Conference 2026

“Common Ground”

NWO NAC (Dutch Earth & Environmental Sciences Conference)

9-10 April 2026

The annual Dutch Earth & Environmental Science conference took place at the NH Noordwijk Conference Centre Leeuwenhorst in Noordwijkerhout amoung some of the many Dutch flower fields.

Before the conference was a “Strategic evening” which provided an opportunity to meet scientists from other universities and organisations, and to discuss topical issues. This included a presentation of the recently completed “Earth & Environmental Science Vision” document (which can be dowloaded from the AMW Raad [Earth & Environmental Science Council] web page).

On the first day of the conference proper I was involved in chairing two sessions on “Palaeoclimate”. These sessions covered a wide range of topics, proxies and time periods, and included work on the Paleocene-Eocene Thermal Maximum, tipping points, and the Younger Dryas period. Excitingly for chairing these sessions I recieved a pair of NWO NAC socks!

On the second day of the conference – sporting my new NAC socks – I presented our recently published work on landscape openness in the pre-farming European landscape. This was centred upon the recent publication of the palaeoecological record from Well-Aijen (Limburg, the Netherlands) which was the culmination of many years, and many students, research (Gosling et al., 2025). It was great to get positive feedback from the Dutch scientific community on this study. The session also included exciting work on reconstructing past climate from pollen data using the CREST model (Chevalier, 2022) and the extraction of biodiversity data from sedimentary pollen records.

As well as the science talks the meeting had posters, exhibitors, workshops (I attended the one of scientific drilling) and social events (pub quiz, bowling, dancing). The atmosphere was very friendly and it was very easy to meet new people. The area around is very pretty and I even managed to get out for a short run on one of the days. I would recommend this event to anyone working in Earth or environmental sciences in the Netherlands.

From Writing to Rock Art: A Week at the Mapping Ancient Africa Workshop

March 21, 2026

By Bouwe Groeneveld (MSc Biological Sciences, track Ecology & Evolution, University of Amsterdam)

From 2 to 6 March, I joined the Mapping Ancient Africa Research and Writing Workshop at Fountainhill Estate near Pietermaritzburg, South Africa. The week brought together focused writing, interdisciplinary exchange, and time in the landscape.

We began with a speed dating session that set an open and collaborative tone. Participants introduced their research backgrounds, ranging from botany and ecology to geography. The group was highly international, with participants from Ghana, Ethiopia, Nigeria, Kenya, South Africa, and the Netherlands. This diversity quickly proved valuable, as different perspectives naturally complemented one another throughout discussions.

The second day centred on the challenges of academic writing and publishing. Through group conversations and smaller sessions, we reflected on common difficulties such as structuring arguments and navigating the publication process. Later that afternoon, we walked across the estate to the Holley Shelter archaeological site. During the walk, I noticed how the surrounding landscape offered a sense of calm that contrasted with the intensity of writing. Along the way, we encountered a giraffe standing only a few metres from us, quietly feeding on acacia leaves.

The shelter itself was striking. A clear waterfall flowed down the rock face, catching the sunlight as it filtered into the green valley below. The interplay of water, rock, and light created a remarkably beautiful and tranquil setting, making the site feel both impressive and deeply serene.

Reyan Christ graduating with an MSc in Earth Sciences

On the 18 March 2026 I had the fun challenge of speaking at two MSc graduation ceremonies that were running at the same time. Two ‘long-term’ members of the palaeoecology team at the University of Amsterdam had reached the culmination of their degree program.

Reyan Christ graduating Cum laude in MSc Earth Sciences (track Earth System Science) and Jelle Kraak graduating in MSc Biological Sciences (track Ecology & Evolution).

Reyan was up 2nd in the Earth Sciences program, and Jelle was up 5th in Biological Sciences, giving me approximately 10 mins to get between rooms! Thankfully everything ran to time and I was able to deliver my speeches for them both. It was great to meet their friends and families and celebrate this important moment for their education.

Jelle Kraak graduating with an MSc in Biological Sciences

It was also great to celebrate the submission of a manuscript (the day before) on which they are first and second author. This manuscript is based on a combination of their, and other students, theses work on past environmental change in the Drakensberg Mountains (South Africa), and conducted in collaboration with Jemma Finch and Trevor Hill at the University of KwaZulu-Natal. We now cross our fingers that the journal editors and reviewers are as excited as we are about their findings. Fingers crossed we can be announcing the published version on here later in the year…

Mapping Ancient Africa: Research & writing workshop

March 6, 2026
WDG

The third Mapping Ancient Africa (MAA) workshop took place in South Africa during March 2026. This workshop was supported by the International Union for Quaternary Research as part of the MAA multi-year project. The aim of this work shop was to provide specialist training in developing research projects and writing of scientific articles. During the workshop each participant developed, and progressed, their own personal work plan. These personal programs allowed the training to be tailored to the participants needs. They included a wide range of challenged ranging from the development of project ideas through to dealing with reviewer comments on manuscripts, and inclusivity, equality and diversity issues.

In addition to the academic program, social activities and excursions were designed to help build academic networks and promote informal discussion of past environmental change issues. These included hikes to the Holley Shelter archaeological site (Bader & Conrad, 2023) and Game Pass shelter rock art site (Hoerle, 2005).

WDG

The European Conference of Tropical Ecology is organised on behalf of the Society for Tropical Ecology. To find out more about the society click here.

The 9th European Conferenc of Tropical Ecology took place in Passau (Germay) between the 23 and 27 February 2026. The theme of the meeting was “Species-Ecosystems-People” and it brought together around 250 tropical ecology researchers from around the globe to discuss the latest research in the field. The meeting ran very smoothly – credit to Christine Schmitt and her team at the University of Passau – and I enjoyed the conference very much. I followed sessions focused on topics ranging from climate change impacts and change through time, through human-environment interactions, to traits, and recovery and restoration.

It was great to see a good contingent of tropical palaeoecologists present. With Rob Marchant (York University) providing a key note spanning past environmental change through to socio-ecological systems, entitled: “Embedding the past for balanced future tropical mountain social ecological systems”. Palaeoecological talks and posters came from around the world, including Bolivia, Cuba, Brazil, Seychelles, and Democratic Republic of Congo. All provided new insights and suggested high potential for revealing novel information about past ecosystems and the drivers of change.
