Last week, @TraseEarth released modelled data on the subnational Ivorian cocoa supply chain and embedded deforestation, from department to importing country, by trader, annually (2019-22). This builds on new open data on cooperatives and their buyers: doi.org/10.14428/DVN/YBWJOR.
How much #deforestation is caused by growing #cocoa to make chocolate? 🇪🇺🇨🇭New @TraseEarth analysis shows the EU and Switzerland, as the world’s largest importers of cocoa from Côte d’Ivoire, are linked to around 800,000 hectares of tropical deforestation. trase.earth/insights/cote-d-…

In this analysis I find that cocoa #traceability differs across departments of origin, trading companies and countries of destination, and reflect on the implications at each level in the context of the forthcoming EU deforestation regulation. bit.ly/4cy8zKN
The transparency of cocoa supplies from Côte d’Ivoire varies widely, creating challenges for companies under the EUDR. Support for smallholder farmers through cooperatives is needed to enable traceability and improve their livelihoods. bit.ly/4cy8zKN

This is a must-to listen discussion in my opinion. I found especially important the debunking of apolitical/data-driven/objective narratives on (economic) sustainability transitions. news.mongabay.com/2024/01/it… and there is much more in @CrisisReports's podcast 'Planet: Critical' !

The companies disclosing their supply chains as part of their efforts to build accountability for sustainable sourcing handle 80% of cocoa exports from Ghana.💪 Yet, the content of these disclosures allow to recover the district of production for only 9% of exports. 🤏

Yes, I defended my PhD thesis! I am so grateful for all the privilege I have had to get here, and to all the persons who gave me so much admin, technical and social support. I'll do my best to use my new status to do more good than harm around me and to society.
Congratulations to @GuyeValentin for his PhD defence and thanks to all the participants to the jury and more particularly to the two referees for their constructive feedbacks @rach_garr @ben_d_groom

👇 "suggests that companies will struggle to comply [with EU regulation on commodity imports] because over 55% of cocoa from Côte d’Ivoire is untraceable"
NEW @TraseEarth data: Chocolate is eating forests in Côte d’Ivoire, the world’s biggest cocoa producer. In 2000-2019, cocoa plantations swallowed an area of forest almost the size of Rwanda - driving up global greenhouse gas emissions. #COP27 ow.ly/w8Eb50LwmoM

A milestone article for anyone interested in deforestation and agriculture! It very much clarifies the current state of the knowledge abt pan-tropical deforestation - thanks to all the contributors science.org/doi/10.1126/scie…
NEW in @ScienceMagazine ‣ Researchers from @chalmersuniv, @UCLouvain_be, @TraseEarth, @frsFNRS, @SEIresearch & others find that 90-99% of tropical deforestation is linked to agriculture.  Find out more: ow.ly/yx4y50KEoow

It's a by & for PhD conference featuring research taking an interesting variety of approaches to geography economics. And there were great keynote talks. So thanks a lot to the organizers and to all the speakers!

Travelling by night train #intercité & eurostar, from presentations in Toulouse @TSEinfo to London @LSEGeography. I left at 10pm and arrived 9am. By accomodating tighter schedules, night trains make Europe more connected and flying less irreplaceable
