Hi! As an introduction for new followers, my research investigates transitions to sustainable agriculture. We track soil health, crop profiles, agrobiodiversity, carbon dynamics, but also farmer networks and farmer well-being. #agroecology #agroforestry #foodsystem

New paper out on soil quality along an agroecological transition. Our findings show that transitioning to natural farming, even after just 2 years of removing pesticides and adding bio-inputs, had positive detectable effects on soil health.

“…develop a non-market farmland acquisition program in the peri-urban areas of every province to ensure Class 1 and 2 farmland is available for food production at rental/lease rates aligned with the land’s food production value”

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

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.

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.

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

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.

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…
