Ever wondered what your food really costs?
Behind every bite lies a web of invisible costs to people & planet.

This #WorldFoodDay2025, join GAIN, True Price Foundation, ATNI & the Netherlands Food Partnership for a deep dive into #TrueCostAccounting.

Paris Pedals to the Top: How the City of Light Became Europe’s Best for Young Cyclists The French capital has officially become Europe’s best city for children to walk, cycle, and move around independently

“In a city once choked with cars and infamous for its traffic snarls, Paris has pulled off a remarkable turnaround…the French capital has officially become Europe’s best city for children to walk, cycle, and move around independently.” Via @momentummag.bsky.social

A victory for FAST leadership.

Land tenure (in) security in the context of urban flood risk in Ghana The increasing incidence of floods driven by urbanization and climate change destabilizes urban social, economic and environmental systems where land …

A new paper out in Land Use Policy - “Land tenure (in)security in the context of urban flood risk in Ghana.”

We show that flood risk management through post-flood land use planning has potential to have dual impacts on community resilience and tenure security.

Paris before and after street transformation

New urban forest planted in front of Paris City Hall

A Paris “School Street” where cars are removed and people space/tree planting are added

According to the City of Paris, in the last 10 years 150K trees have been planted & 45ha of parks created in the already hot city, all intended to not only improve quality-of-life today, but also help the city adapt to & manage summer heatwaves of 50℃ (122F) by 2050.

Just the start.

Common sense.

Currently at the La Baldi artist residency working on integrating science into art. My collective uses an ecological lens to make art that explores climate change, following in the literary genre of cli fi. An honour to have the space and time to do this. #clifi #climatechange #interdisciplinaryart

CULTIVATE is an evolving collection of interdisciplinary artists, writers, and researchers driven by investigations of land, place, and the commons.

I will be joining CULTIVATEs La Baldi Residency as part of a collective next week. Such an honour. More to come…

The Food System’s Fossil Fuel Crisis From fertilizer to packaging, fossil fuels are flooding the food system—this report shows what it will take to stop it.

Industrial food systems are driving fossil fuel use – and vice versa.

@foodtank.bsky.social covers our #FuelToFork report, unpacking how food's fossil fuel addiction drives risks for climate, ecology, health, and food access – and how we can break the cycle.

Agroecology can’t grow on broken ground: farmers leading the degrowth transition Jonai Farms shows how agroecology and degrowth can work hand in hand to build just, resilient food systems rooted in care, community and ecological balance.

Agroecology and degrowth are more than ideas at Jonai Farms – they shape how food is grown, shared and valued.

This story looks at what it takes to build a just food system, starting from the ground up.

Joint environmental and social benefits from diversified agriculture Agricultural simplification continues to expand at the expense of more diverse forms of agriculture. This simplification, for example, in the form of intensively managed monocultures, poses a risk to ...

Honoured to share that our paper on the environmental and social benefits of diversified agriculture won the Frontiers Planet Prize! Proud of the team & thrilled that these important agricultural systems are recognized.

Shame on Metrolinx for not having the foresight to plan for urban trees. My neighbourhood tree is coming down today. This is not NIMBYism, this is just bad planning and lack of any actual serious consultation.

Estimating the urban heat-related mortality burden due to greenness: a global modelling study This modelling study suggests that increased greenness could substantially reduce the heat-related mortality burden. Preserving and expanding greenness might be potential strategies to lower ambient t...

Increasing urban vegetation by 30% could have prevented 30% of all heat-related deaths, potentially saving up to ~1.1 million lives globally from 2000 to 2019, according to a study of over 11,000 urban areas.

Any lessons for the future…

Hi! Yes we will sample for SOM, POM, POX, total C and GHG fluxes. We have in-depth surveys for practices to do life cycle analysis too.

New field site visits today! Launching research trials in urban and peri-urban agriculture with amendment and crop diversity trials in hydro corridors, next to major highways and right in the city, sampling everything from microbial communities, to soil health, to pollinators, to yield.

Looking forward to it too!

Omg- definitely! Let’s make sure industrial agriculture doesn’t get its feelings hurt! That all powerful agroecology is really being such a bully!

I looked through this. Curious- you specifically highlight conservation agriculture in your article. It seems you’re ok with “solutions” that practice soil management and diversification. Why is conservation agriculture free of your broad stroke critique?

Unfortunately, your argument flattens the decades of agroecological farmer movements for social and institutional change for peasants, landless workers, indigenous people, small and medium-size farmers, rural women - if this is, as you say, nature-based solutionism, then sounds good to me!

I appreciate this article as it weaves a thread through multiple ideologies merging in the current chaos of the US. But the article ends where it could have started, effective nature based approaches to agriculture- conservation agriculture (or agroecology- moving past top-down solution narratives)
