Still time to submit an abstract to the ICOS Science conference 2026 in Lund! #ICOS2026SC

And while you're in Lund come visit us! An excursion to #Hyltemossa will be part of the programm.

Some of our BSc students are on field excursion in Rwanda. Here they are working with Rwandan students and teachers with maintenance of a Meter weather stations installed last year (funded by The Swedish Society for Anthropology and Geography).

Networks, integration, and community have been at the center of Kernza development. This figure shows how increasingly diverse stakeholder groups have and may continue to engage with Kernza over time.

Skogsstyrelsens rapport: Lobbyister har makt över skogen I en ny rapport från Skogsstyrelsen har forskare kartlagt vilka som har makten över skogen. En slutsats står ut: Politiker som blir lobbyister – som tidigare va

En ovanlig rapport släpptes från Skogsstyrelsen idag.

Tough day for the field crew today. Sub-zero temperatures, snow and strong winds at our agricultural site Alnarp. Perfect conditions for sampling soil water and ground water... but they still managed to download data groundwater loggers etc.

Contrasting roles of ground, trees, ponds and grazing in carbon dioxide, methane and nitrous oxide fluxes of an African semi-arid savanna Understanding greenhouse gas fluxes in semi-arid ecosystems is critical for improving our understanding of biogeochemical cycles, particularly in unde…

New exciting paper with Lu Fluxes involvement, highlighting how trees, ponds and grazing strongly shape greenhouse gas dynamics in Sahel savannas, showing how complex and dynamic semi‑arid ecosystems really are.

Well Done Alek!

A climate‑friendly perennial grain that could reshape European agriculture has been held up in the EU approval system for over six years. Researchers call the rules outdated.

Hard work forvStig and Nele to drag hundreds of liters of water across the fields te get infiltration rate estimates

Infiltration rate estimates underway in the perennial wheat (Kernza) field

Our hardworking team are measuring infiltration rates and ground water levels to support hydrological modelling and estimates of nutrient leaching in perennial and annual grain crops in Alnarp.
@beccsweden.bsky.social
@thelandinstitute.bsky.social
@lund-university.bsky.social

Stig and Nele have been busy installing tension lysimeters the last few days. This will help us estimate nutrient leaching from perennial wheat #Kernza and the annual reference crop (currently winter wheat).

It's a challenge, to say the least 😀

Our amazing field assistants are hard at work conducting forest inventory in our continuous cover forest at Rumperöd.
Their efforts help us monitor forest structure, growth and dynamics, supporting sustainable management and carbon balance research.

Stig had a great fieldwork Friday with chamber measurements of CO2 and CH4 fluxes at both our perennial wheat field and the annual winter wheat field

Flux tower maintenance: the ultimate Monday reset. Climbing gear on, sensors humming, data flowing. Who needs coffee when you’ve got eddy covariance and a view like this? Awesome work by Peter and Tobias
@beccsweden.bsky.social
@lund-university.bsky.social

Wrapped up a great fieldwork day with our MSc Physical Geography students! Today they dismantled the eddy covariance tower they installed at the start of the course, marking the end of six weeks of successful flux measurements. Great teamwork and solid science in action!
@lund-university.bsky.social

This week Johannes, our dendrometer & -chronology expert, and Martin, who used #dendrometer measurements from @hyltemossa.bsky.social in his BSc thesis, attended the Nordic #DendroNet meeting at @uninmbu.bsky.social organized by @daniellecreek.bsky.social
& visited the @icos-ri.eu station #Hurdal

Tobias, Paul and Peter at our perennial crop site

We had the pleasure of meeting up with Professor Paul Stoy in Lund this week—he joined us as the opponent for a PhD defense and still made time to visit our agricultural EC flux field site. Great science, good vibes, and even better company!

Nice change of scenery during today's excursion to "Tavastland", currently docked in Landskrona. Thanks Madeleine for showing & explaining the ferry box setup. Measurements by #SMHI as part of @icossweden.bsky.social & data from other ships of opportunity contribute to the @icos-ri.eu Ocean Domain.

If you happen to live in or around Lund, maybe we will see you 25 October on the Opening of Climate and Forests – A New Popular Science Exhibition at Naturum Skrylle: www.becc.lu.se/calendar/ope...

Anna-Kristina Voss presenting her work on ecosystem modelling of perennial crops

Veronika Widengren presenting her work on eddy covarience measurements at both perennial and annual cropping systems

Tim Crews sharing his, and The Land Institute's, extensive knowledge and experience on perennial crops

Inspiring presentations today at our annual Perennial workshop! Huge thanks to our PhD students Veronika and Anna for sharing their research, and to Kernza experts Tim and Doug for their deep insights into perennial grain agriculture.
