Last week I defended my 'Habilitation à diriger des Recherches' Thanks to those who attended! Thanks to the fantastic jury: L.Alletto A.METAY L.Hossard L.Bell R.Zougmore G.Martin G. Corre-Hellou The slide deck: lnkd.in/g-eJik8P The HDR manuscript: lnkd.in/gF4XcmnU

On May 15th at 9:00 (CET), I will be presenting my HDR dissertation 'Sustainable intensification of smallholder farming systems for improved food security and adaptation to climate change in Africa' Use this link to join online: teams.microsoft.com/l/meetup-joi...

Another update of how total CO2 emissions are tracking with past scenarios. Sort of tracking very much in the middle, which is probably very much expected... Based on our 2012 paper, which is still relevant: rdcu.be/brDGx

Low yielding and low data in smallholder farming systems is not a question of fate. I was able to talk on the topic at the last #AgMIP10 conference youtu.be/gAAFJtg2Qb0?...

Achieving similar (or greater?) crop yield with less mineral fertiliser and pesticides? this new paper proposes a useful framework – with examples - to quantify the contribution of ecosystem services.

Accurate simulation of the provision of nitrogen by soil organic matter is critical in low-input smallholder systems. recrutement.cirad.fr/job/job-cher... Join us at Cirad - Postdoc position to help with crop model intercomparison @agmip.bsky.social

Could drought and poor soil undermine the performance of intercropping ? Our study in semi-arid Zimbabwe found that the benefits of intercropping are maintained even with water and N stress. doi.org/10.1016/j.fc... Congrats Illiana Kwenda - A nice combination of field experiments and modelling

#Agmip10 Understanding of nutrient soil supply is key to design relevant srategies for fertility management in smallholder system We are kick-starting a new Agmip intercomparison to asses how well models deal with soil organic matter mineralisation

#AgMIP10 officially launched this morning, but we hosted seven pre-workshop Side Meetings yesterday, including the GGCMI, Wheat, Ozone, Global Econ, Low-Input, and Calibration #AgMIPTeams.

Exploring the impact of integrated soil fertility management across a rainfall gradient in Zimbabwe

Third growing season at our experiment about rainfall extremes (drought vs heavy rains) at the University of Zimbabwe! Maize🌽 and cowpea are looking nice this year compared to the El Nino year in 2024! #intercropping #mulch #fertilizers #climatechange @intercropvalues.bsky.social @cirad.bsky.social

Visit of Niakhar 🇸🇳 Faidherbia-Flux site. Amazing Faidherbia albida parkland equipped with flux towers, sap flow sensors, automatic greenhouse gas chambers, wells to study deep roots, etc #agroforestry #climatechange #water #carbon #nutrients #livestock @cirad.bsky.social @umr-ecosols.bsky.social

Adoption of improved crop varieties limited biodiversity losses, terrestrial carbon emissions, and cropland expansion in the tropics The value of the #cgiar breeding programs beyond higher yields www.pnas.org/doi/10.1073/...

🚨 #JustPublished "Farm resilience to climatic risk. A review" with @cirad.bsky.social and @w-u-r.bsky.social More comprehensive assessments are needed to measure farm #resilience, especially for #smallholders. For this, we are proposing 6 guidelines #OpenAccess 👉 t.co/djDpVPtbsC

Sharing here a previous X thread... 🧵1/10 Check out our recent perspective paper @natclimchange.bsky.social on #agroforestry 🌳🌽🐄as a #naturalclimatesolution (NCS) and brilliantly led by @nature.org #naturebasedsolutions #climatechangemitigation @cirad.bsky.social www.nature.com/articles/s41...

The #EU Deforestation & Forest Degradation Regulation is due to come into force in 2026. It will ban products made using raw materials from deforested areas on the EU market. To this end, research needs to come up with indicators to differentiate between preserved & degraded forests. 👉 lc.cx/iEG_5p

New study report that conserving and restoring #peatlands and #mangroves in Southeast Asia can offer annual #climate mitigation potentials of 770±97 TgCO2e. These carbon-dense #wetlands are thus key nature-based climate solutions for ASEAN countries. www.nature.com/articles/s41...
